The effects of Behaviour Management on Teaching and Learning in Essay

The effects of Behaviour Management on Teaching and Learning in Secondary Education - Essay Example It has been fundamentally inspired by this virtue of behaviour management that it has today emerged as one of the major elements adopted by teachers in the pedagogy education system with the intention of improving the behaviour of learners (Rogers, 2007, p. 1-27). Notably, as pedagogy deal with young minds which are again attributed with high instability and curiosity, making the learners focused on a particular subject becomes a noteworthy challenge. Hence, teachers can be benefitted by obtaining better control on the behavioural traits of the learners which can assist in motivating the students to enhance their behavioural skills and consequently, build their future career prospects. However, the application of behaviour management initiatives is subjected to various factors among which the learning environment is often argued as one of the most crucial elements (Fields, 2004, p. 4-8). As argued by Rogers (2007, p. 1-27), an effective learning environment needs to be developed with the aim of conveying the rights as well as the responsibilities that are necessary for generating better disciplined school and classroom atmosphere and therefore implementing effective behavioural management strategies. It is in this regard that teachers, when applying the theories of modern pedagogy, attempt to introduce as well as execute certain developing and disciplinary programs for the purpose of motivating the learners to develop behavioural traits, appropriate for their promising future (Rogers, 2007, p. 1-27). As can be observed, the major objective of behaviour management is to ensure that the learners are able to acquire appropriate qualities and knowledge in accordance with which they will be able to determine the differences between pessimistic and optimistic influencing factors. Along with developing the behavioural skills of learners, it is also essential that the teachers are equipped with effective behavioural factors in order to ensure that they are able to impa rt appropriate educational knowledge and develop their skills successfully to the desired level. Additionally, it has also been often argued that with the help of behavioural management, teachers can develop the perceptions as well as influence the conscience of the learners which can further contribute towards minimising the involvement of those learners in conducting any sort of anti-social activities (Rogers, 2007, p. 1-27). In other words, with the help of behavioural management, learners’ behavioural traits can be developed in a more responsible as well as conscious way. With this concern, this paper intends to discuss the importance of behaviour management. Moreover, the effects of behaviour management on teaching as well as learning will be taken into concern. In this regard, the effects of behaviour management will be analysed by considering certain important reports like Steer and Taylor Reports among others. Focus of Behaviour Management In the context of education system, behaviour management is often viewed to be an important practice and discipline for the development of positive attitudes, skills and behaviours of students or learners. This particular aspect is recognised to be dependent on various values as well as aims according to which the learning programs and policies are formulated

Relation Between Language Power And Dehumanization English Literature Essay

Relation Between Language Power And Dehumanization English Literature Essay There are implications of limited health care, as Winstons varicose ulcer on his right ankle remains treated throughout. Meanwhile Winston talks of the cheap quality of the vicory cigarettes, the only cigarettes available. The fact that the only attainable alcohol,is gin, and the inclusion of food rationing, also resembles an air of restriction, through a dehumanizing lack of variety. Language plays a vital part in this process of repression, as it is language, through propaganda that enforces it. For example, the telescreen uses manipulative language, to subliminally brainwash people during the two minutes hate. Though the false representation of Goldstein and his rapid polysyllabic speech, as he delivers his usual venemous attack upon the doctrines of the Party an attack so exaggerated and perverse that a child should have been able to see through it, and yet just plausible enough to fill one with an alarmed feeling. (ch1) The party uses hateful language to manipulate them into a frenzy, to a point where they advocate against Goldsteins promotion of feedom of speech, freedom of the Press, freedom of assembly, freedom of thought. To enforce this manipulative repression, further restriction shows that it is illegal for the telescreen to be switched off, even inner party members are only allowed to switch it off for half an hour at a time. Therefore manipulative l anguage empowers Big Brother, so that he can dehumanize the non-proles of Oceana. The telescreen is also used as a tool for repression through recording peoples spoken language and monitoring their lingual thoughts. Winston notes, It was terribly dangerous to let your thoughts wander when you were in any public place or within range of a telescreen through the fear of commiting face crime, if an unfavourable expression appeared on a persons face, whilst in front of the telescreen. This is an example of how language itself is repressed, for the benefit of the party. With no freedom of expression, and a sense of paranoia surrounding the use of language, Big Brother is not under threat. The giant big brother is watching you, posters, plastered throughout Oceana, enforce this empowerment through paranoia, that the government holds over Oceana. The monitoring of language, propaganda posters, and telescreens prevents revolution, and therefore language becomes repressed as a result. Along with the fear of commiting crimes through spoken language, there is fear surrounding freedom of language in thought. The thought police, remain a terrifying organization for the residents of Oceana, with the danger of torture and imprisonment if their language, through their thoughts, consist of an anti-party stance. The fact that they watched everybody all the time, installs a sense of paranoia, that makes people mentally restrict their freedom of language, and vocabulary, in order to avoid being targeted by the thought police. To help society keep repressed, and to discourage against the free use of language, there is the invention of Newspeak. As the official language of Oceana, it concentrates upon a narrowing vocabulary, eliminating words concerning freedom and rebellion. As Syme muses Dont you see that the whole aim of Newspeak is to narrow the range of thought?, this directly relates to power. The minimising of language vocabulary, maximises power, with the hope that if one cannot describe freedom, and rebelling against the party, then they prevent themselves from wanting it, or thinking about it. As part of Newspeak, we are introduced to the notion of Doublethink, a process of holding two contradictory beliefs in ones mind simultaneously, and accepting both of them. (ch3) This method is a manipulative way of confusing a persons perception of concepts such as freedom. The party uses this to their advantage as part of their slogan, freedom is slavery. This subliminal brainwashing through contradictive similes confuses the inhabitants into thinking that the opposites are true. The method of doublethink, is used not only in the partys slogans but is used as a tool to boost ignorance, and as a result weakens the chance of big brother getting overthrown. For example, through reporting false events such as how Oceana had always been war with Eastasia, boosts patriotism, whilst forcing inhabitants into ignorance. Through the restriction of truth in language, and spreading of false information, Oceanas inhabitants are dehumanized. This solidifies the parties power as noone challenges these false reports, as they believe that ignorance is truth. Although Winston is part of the party himself, he is still repressed by them. The ironic ministry of truth where he works, is representative of a tolertarian power gone mad. Again, language through lies is used to test and push the ignorance of the people. Winston notes how he has to destroy parts of the past, to the point that history is changed in a continuous process of alteration(ch4). Meanwhile the simple fiddling of statistics, such as the covering up of chocolate ration decreasing from 30 grams to 20 grams, shows how powerful the manipulative newspeak and doublethink is. Winston notes there were demonstrations to thank Big Brother for raising the chocolate ration to twenty grams a week. only yesterday, he reflected, it had been announced that the ration was to be reduced to twenty grams a week. Was it possible that they could swallow that, after only twenty-four hours? Yes, they swallowed it. The ministry of plenty, alas, controlled shortages. Even though people are getting less food and supplies than ever, Winston becomes part of the lingual manipulation process which makes them thank big brother for what they have. As general perceptions are warped by the party through language, so is the act of love. Initial paranoia, which evolves into anger and an urge to seek out anyone who is against the party, is inflicted upon the children of Oceana from an early age. Through this they are dehumanized, as they become incapable of loving their parents and are more than willing, to turn against them, as junior spies. An example of this is when we see Parsons turned in to the party by his children. Through the language, of the sternly named anti sex league, the party uses its power to enforce sexual repression and channel it into anger against the parties enemies. Through anti-sex language propaganda, the party gains power, yet dehumanizes humans, preventing them from a natural activity. This repression of sex even warps the resistant mind of Winston, as he says to Julia, the more men she has been with, the more that he loves her. Here, even though rebellion against the party, his idea of love is ruined. Literature itself is restricted, in fear that its language will promote revolutionary thoughts. One man leaves the word God, in a translation of a Rudyard Kipling poem, and is put in prison as a result, which shows the tension of how restriction of language is essential to power. Along with food, sex, alcohol and cigarettes, literature is seen as a threat. The fact that Winston wakes up from a dream with Shakeapeare on his lips, emphasises this restriction, as he expresses his yearning for culture and literature. The restriction of books is noted in 1984, as we see that no one is reading. Syme note that by 2050, Chaucer, Shakespeare, Milton, Byron theyll exist only in Newspeak versions, not merely changed into something different, but actually changed into something contradictory of what they used to be, establishing the parties aim to destroy and manipulate language in literature for their own needs. The fact that Winston feels extremely guilty, when he writes in a diary (writing is not permitted), and even worse, writing words against the party, which makes him contemplate suicide, shows the power the party has over him. This shows how the restriction of language, through taking away the freedom to write, is dehumanizing, as it prevents the expression of feeling. Conc The only people free from the party are the proles. They are the only residents who have free expression of words, however, they are also dehumanized themselves, through their lack of civilisation and power. Part 2 Whilst language is changed due to a totalitarian element concerning dehumanization in 1984, the language in Naipuls one out of many, represents the struggle between power and dehumanization, under the context of class and social hierarchy. I am going to explore these links through observing the dialogue and attitude of the characters in the text, alongside the tone of the narrator. There is a notable link that language has with power, when it comes to social hierarchy. Someone could become dehumanized, the further they move down the social ladder. The language exchanged between the narrator, Santosh, and the characters in the extract is indicative of this. Santosh speaks of how he relied on the importance of his employer, Sahib, for his own respect and security, and their relationship begins at a seemingly equal level. Sahib warns Santosh that Washington is not Bombay, and that he should be aware of the exchange rate between rupee and dollar. However as soon as they arrive in Washington, the social gap between both the characters widens. Sahib first speaks down to Santosh, saying he is only a domestic, and in front of the officials, he pretends to be horrified at Santoshs natural behaviour on the plane, I cannot understand why your behaviour has already gone so much out of character. Through talking down to Santosh, Sahib commands social power and begins to deh umanize him in front of other people, in order to command respect. When it comes to money, Sahib manipulates Santosh through choosing his words carefully in offering him a raise. The ignorant Sahib, thinks that the raise, and fortnights pay in advance, is more than generous, and like the inhabitants of Oceana over the chocolate ration, is manipulated into being thankful for this. When santosh realises the money isnt enough to live off, he wants to leave. However Sahib uses strong language to threaten him if I send you back now, you will have to work for six or seven years without salary to pay me back. In this way Sahib gains power. Santosh observes that his freedom has been taken away, I understood. I was a prisoner, as he realises the context of the verbal threat dehumanizes him, and makes him almost a slave to Sahib. Of course, Sahib feels himself, dehumanized in the extract, by the Americans. When Santosh has to sleep in a cupboard, he feels that he shouldnt be treated that way and takes it personally, assuming that the government had assigned Santosh this room, just because they are Indian. A paranoid Sahib claims some enemy in the government has done this to me, they think that we all live in cupboards in Bombay. Sahib also feels dehumanized when one of his guests comments how he brought back an ancient stone head from India, tipping the tour guide to keep quiet. Offensively, the guest says, if I had a bottle of whisky he would have pulled down the whole temple for me. Santosh finds comfort in language through talking as says he told stories and smoked, with his friends in Bombay. The tailor warns Santosh that Americans wont wont sit and talk with you in the evenings, which is true, as he becomes a recluse when he moves to Washington, staying in the apartment and watching t.v. This removal of social interaction through language dehumanizes Santosh as racial and foreign language barriers encourage this. To further this isolation, Santosh is talked down to by a number of people, from the flight attendant who spoke roughly to him, to the woman in the cafà © cant you read? We dont serve hippies or bare feet here. The Hubshi girl teaches Santosh English me black and beautiful then calls policeman a pig, using Santoshs naivity to make an impression on him through power of language. Powering him to have prejudices against the police and dehumanize them. Interestingly we see that the power of language and manipulates Santosh into becoming vain. At the beginning, despite being look own upon by the air hostess, he didnt care what the girl said or did, after a series of incidents where people use language to make him inferior, he begins to dress better and became choked with shame at his old ways. The snobbish language made him now wear shoes. The television, in a vaguely similar fashion to the telescreens in 1984, has used language and imagery to manipulate him into how to behave in society. He notes I became obsessed with my appearance and began comparing himself with actors on t.v. Interestingly, during Santoshs predicament, concerning how to get his green card, he commits the most dehumnizing act in the whole extract. Through the green card he gains power, however to gain this power he has to use language to falsely tell the Hubshi girl that he likes her and wants to marry her. This is not only dehumanizing for him, having to marry and live with a woman he doesnt like, but dehumanizing for her, as he does not love her. But then talks down I dont see how you will manage in Washington foreign exchange santosh! Foreign exchange! Boss again speaks down to him when he says in front of the officials Threat- you dont only represent your country, you represent me Officials-does he always travel with his condiments- not talking to him directly- conveys an air of dehumanization. Santosh looks down on the hubshi at first- language is snobby, and dehumaizes them in our country we frankly do not care for the hubshi but then uses language to feel emphathy for them even in the mornings the men were drunk Santosh they can just look at me and see I am dirt Sahibs guests are offensive if I had a bottle of whisky he would have pulled down the whole temple for me- dehumanizing Indians. they are malicious people. Power of hubshi- burning city down Priyas attitude if you cant beat them, join them. I joined them. They are still beating me When moves in with priya I felt I was earning my freedom Power of green card- immigrants they were always about to get green cards, or they had been cheated out of green cards Priya and santhosh equal the American way, man to man I was good looking; I had lost my looks. I was a free man; I had lost my freedom Power of haggling- language- I couldnt stay on for less than a hundred and twenty five- santosh now has power. I have made some corrections in the second bit, but gave up because there are so many little ones, such as grammar and spelling. Also overuse of the name Santosh, the word dehumanizing and a tendency to repeat. However it really just needs tidying up a bit and making a bit more coherent as in the first half. If you wrote the first half, completely, yourself, I would say it was one of the best pieces you have written. I asked if you had written it, because I was shocked that there were hardly any mistakes in it and it appeared balanced and coherent.

Love Sex and Relationships Essay

Sex, and Lasting Relationships by Ingram â€Å"Love is the state in which man sees things most widely different from what they are. † -Nietzsch Many times we just forgo some of the warnings of love and we fall into infatuation. Our love is biased, meaning we don’t let time indicate the growth of our love, we often forget that love is centered in the partner, that we need to grow everyday in order to have a better relationship with God and each other. Sometimes we fall in love with two people, when true love focuses on one, we often follow our flesh. Many times we feel insecure about our partner, when in true love we don’t even have to think about deceive. We very often try to skip the obstacles instead of fighting together, we let distance become an obstacle, is it real love? In general we are a generation of the present, when getting into a relationship; we forget that an important thing is to think about the future together, driven by our media and our sex centered society it is really easy to get overwhelmed by a miss leaded definition of love. ove has three main components: those of the spirit, mind, and body. Ingram calls these agape, phileo, and eros: selfless love, a beautiful friendship, and physical love. Interestingly, and according to what I see in our society and in what is portrayed in the media†¦ love is eros, more and more erotic scenes, more and more body involved, less talk more action, what is that? Our societies conception of love, seemingly, has fallen into a selfish flesh satisfying â€Å"Loveâ € . I mean it is well understood that love comes first through our eyes, and that this physical attraction is a very important part of a relationship, but love cannot stand on it itself, if we are driven only by eros, we are more averse to fall into sinning by cheating on our partners, our view of Though to help eros, there is â€Å"phileo†, or companionship. This love is the kind of love needed to get to know each other well, sometimes we are just rushed by our emotions and we step into a relationship we did not mean to get into. Firstly we need to spend time with each other, but spending time itself is nothing, unless we share our lives openly, and freely. We need to have this companionship were we play games, we share our happiness and our sadness, what pastors often call quality time. By listening to my friends, those who are in a relationship, I have noticed that all the talks they have with their partners (be them couples or just friends), are very superficial, arrogant and self-centered, meaning there is also a third component for love to be fulfilled. The third component of love is the so called â€Å"Agape†, the selfless love, the not infatuated. And I really like how the author puts it â€Å"giving others the most when they deserve the less†. And better defined in 1 Corinthians 13. Are we in love or infatuated? â€Å"Indeed, steamy starts do not promote our best thinking. Intense emotions often block us from taking a careful and objective look at ourselves, the person we are dating, and the relationship we are forming.

Water Level Warning by Gsm

CHAPTER 1 INTRODUCTION Our entire project is based upon Embedded Systems. In this project we are using Microcontroller which controls all the operations in regarding the level of water in the dam. For this process we require the components such as microcontroller, GSM modem, control circuitry, power supply and three sensors. These three sensors are placed in three different threshold levels and are connected to the controller.If for suppose the level of water is being increasing in the dam, then immediately when the water level crossed the sensor at level-1, the information is passed to the controller and then the controller checks for the precaution instruction which is given a by the developer and forwards it to the GSM modem. The modem immediately sends that particular SMS to the mobiles for which it is assigned saying that â€Å"the Water level has crossed the threshold level-1†. The controlling part of the water level is also done by the controller through the instruction s given by the developer.This includes the operations such as the number of gates to be opened, the number of threshold levels that are crossed. In this process the controller checks the number of threshold levels that are crossed and according to that the gates are being controlled. 1. 1 Embedded System Embedded systems are electronic devices that incorporate microprocessors with in their implementations. Embedded systems designers usually have a significant grasp of hardware technologies. They use specific programming languages and software to develop embedded systems and manipulate the equipment.Embedded systems often use a (relatively) slow processor and small memory size to minimize costs. An embedded system is a special-purpose system in which the computer is completely encapsulated by or dedicated to the device or system it controls. Unlike a general-purpose computer, such as a personal computer, an embedded system performs one or a few pre-defined tasks, usually with very sp ecific requirements. Since the system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product. Embedded systems are often mass-produced, benefiting from economies of scale. . 2 GSM Technology Global System for Mobile Communication (GSM) is a set of ETSI standards specifying the infrastructure for a digital cellular service. GSM (Global System for Mobile communication) is a digital mobile telephone system that is widely used in many parts of the world. GSM uses a variation of Time Division Multiple Access (TDMA) and is the most widely used of the three digital wireless telephone technologies (TDMA, GSM, and CDMA). GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot.GSM operates in the 900MHz, 1800MHz, or 1900 MHz frequency bands. GSM (Global System for Mobile communications) is the technology that underpins most of the world's mobile phone networks. The GSM p latform is a hugely successful wireless technology and an unprecedented story of global achievement and cooperation. GSM has become the world's fastest growing communications technology of all time and the leading global mobile standard, spanning 218 countries. GSM is an open, digital cellular technology used for transmitting mobile voice and data services. GSM operates in the 900MHz and 1. GHz bands GSM supports data transfer speeds of up to 9. 6 kbps, allowing the transmission of basic data services such as SMS. Everyday, millions of people are making phone calls by pressing a few buttons. Little is known about how one person's voice reaches the other person's phone that is thousands of miles away. Even less is known about the security measures and protection behind the system. The complexity of the cell phone is increasing as people begin sending text messages and digital pictures to their friends and family. The cell phone is slowly turning into a handheld computer.All the featu res and advancements in cell phone technology require a backbone to support it. When a mobile subscriber roams into a new location area (new VLR), the VLR automatically determines that it must update the HLR with the new location information, which it does using an SS7 Location Update Request Message. The Location Update Message is routed to the HLR through the SS7 network, based on the global title translation of the IMSI that is stored within the SCCP Called Party Address portion of the message. The HLR responds with a message that informs the VLR whether the subscriber should be provided service in the new location. . 3 Micro controller Microcontrollers as the name suggests are small controllers. They are like single chip computers that are often embedded into other systems to function as processing/controlling unit. Microcontroller – A single chip used to control other devices. Any microcomputer system requires memory to store a sequence of instructions making up a progra m, parallel port or serial port for communicating with an external system, timer / counter for control purposes like generating time delays, Baud rate for the serial port, apart from the controlling unit called the Central Processing Unit.CHAPTER 2 DESCRIPTION OF PROJECT 2. 1 Block diagram and description [pic] Fig 2. 1 Block Diagram of dam level warning using GSM SMS In this block diagram we are using microcontroller, GSM modem, LCD, power supply, MAX-232, control circuitry, liquid level indicator. These all are mentioned below. Description The main aim is to send SMS when ever the water level crosses the threshold level. And necessary precautions are taken when ever the water exceeds the last level. To send an SMS to the concerned person we have certain steps to follow.In-order to work with any components basic requirement is power supply. Now the aim is to design the power supply section which converts 230V AC in to 5V DC. Since 230V AC is too high to reduce it to directly 5V DC, therefore we need a step-down transformer that reduces the line voltage to certain voltage that will help us to convert it in to a 5V DC. There are many types of power supply. Most are designed to convert high voltage AC mains electricity to a suitable low voltage supply for electronics circuits and other devices.A power supply can by broken down into a series of blocks, each of which performs a particular function. This power supply is connected to the micro controller. In a very simplistic form, a micro-controller system can be viewed as a system that reads from (monitors) inputs, performs processing and writes to (controls) outputs. Micro controllers are useful to the extent that they communicate with other devices, such as sensors, motors, switches, keypads, displays, memory and even other micro-controllers. Next input should be given to the microcontroller it is done by the level indicator.Level indicator has certain levels when the water touches the different levels of level indicator the micro controller takes the input as the level indicator is connected to the ports. This information is displayed on the LCD. When the LCD is ON the GSM (Global System for Mobile communication) gets activated by sending some commands to the microcontroller. For communication with the micro controller MAX 232 is used. This is used to convert the voltage level that is required for GSM, then the SMS is passed to the person or concerned authority using the GSM.For controlling the system we are using motors. Motors act as relays, which is an ON OFF switch. Through this relay action the motors work and controlling of the gates can be done. Hardware components 1. Power supply 2. micro controller 3. level indicator 4. MAX 232 5. GSM(Global system for Mobile communication) Modem 6. LCD(liquid crystal display) 7. control system 2. 2 Power supply The power supplies are designed to convert high voltage AC mains electricity to a suitable low voltage supply for electronics circuits a nd other devices.A power supply can by broken down into a series of blocks, each of which performs a particular function. A d. c power supply which maintains the output voltage constant irrespective of a. c mains fluctuations or load variations is known as â€Å"Regulated D. C Power Supply†. For example a 5V regulated power supply system as shown below: [pic] Fig 2. 2 5V regulated power supply system The regulated DC output is very smooth with no ripple. It is suitable for all electronic circuits. 2. 2. 1 Transformer Transformers convert AC electricity from one voltage to another with little loss of power.Transformers work only with AC and this is one of the reasons why mains electricity is AC. Step-up transformers increase voltage, step-down transformers reduce voltage. Most power supplies use a step-down transformer to reduce the dangerously high mains voltage (230V in UK) to a safer low voltage. Transformers waste very little power so the power out is (almost) equal to the power in. Note that as voltage is stepped down current is stepped up. 2. 2. 2 Rectifier A circuit which is used to convert a. c to dc is known as â€Å"rectifier†. The process of conversion a. c to d. is called â€Å"rectification† Types of rectifier: †¢ Half wave Rectifier †¢ Full wave rectifier 1. Centre tap full wave rectifier. 2. Bridge type full bridge rectifier. Bridge Rectifier: A bridge rectifier makes use of four diodes in a bridge arrangement to achieve full-wave rectification. This is a widely used configuration, both with individual diodes wired as shown and with single component bridges where the diode bridge is wired internally. A bridge rectifier makes use of four diodes in a bridge arrangement as shown in fig below to achieve full-wave rectification.This is a widely used configuration, both with individual diodes wired as shown and with single component bridges where the diode bridge is wired internally. [pic] Fig 2. 2. 2 Bridge Rectifier arr angement 2. 2. 3 Filter A Filter is a device which removes the a. c component of rectifier output but allows the d. c component to reach the load. We have seen that the ripple content in the rectified output of half wave rectifier is 121% or that of full-wave or bridge rectifier or bridge rectifier is 48% such high percentages of ripples is not acceptable for most of the applications.Ripples can be removed by one of the following methods of filtering. †¢ A capacitor, in parallel to the load, provides an easier by –pass for the ripples voltage though it due to low impedance. At ripple frequency and leave the d. c. to appears the load. †¢ An inductor, in series with the load, prevents the passage of the ripple current (due to high impedance at ripple frequency) while allowing the d. c (due to low resistance to d. c) 2. 2. 4 Regulator Voltage regulator ICs is available with fixed (typically 5, 12 and 15V) or variable output voltages. The maximum current they can pass a lso rates them.Negative voltage regulators are available, mainly for use in dual supplies. Most regulators include some automatic protection from excessive current (‘overload protection') and overheating (‘thermal protection'). Many of the fixed voltage regulator ICs has 3 leads and look like power transistors, such as the 7805 +5V 1A regulator shown on the right. The LM7805 is simple to use. You simply connect the positive lead of your unregulated DC power supply (anything from 9VDC to 24VDC) to the Input pin, connect the negative lead to the Common pin and then when you turn on the power, you get a 5 volt supply from the output pin.Regulator eliminates ripple by setting DC output to a fixed voltage. [pic] Fig 2. 2. 4 Regulator 2. 3 Micro controller (AT89C51) In this project work we are using AT89C51 micro-controller. This micro-controller plays a major role. Micro-controllers were originally used as components in complicated process-control systems. However, because of their small size and low price, Micro-controllers are now also being used in regulators for individual control loops. In several areas Micro-controllers are now outperforming their analog counterparts and are cheaper as well.A Micro controller consists of a powerful CPU tightly coupled with memory RAM, ROM or EPROM), various I / O features such as Serial ports, Parallel Ports, Timer/Counters, Interrupt Controller, Data Acquisition interfaces-Analog to Digital Converter (ADC), Digital to Analog Converter (ADC), everything integrated onto a single Silicon Chip. It does not mean that any micro controller should have all the above said features on chip, Depending on the need and area of application for which it is designed, The ON-CHIP features present in it may or may not include all the individual section said above.Any microcomputer system requires memory to store a sequence of instructions making up a program, parallel port or serial port for communicating with an external system, timer / counter for control purposes like generating time delays, Baud rate for the serial port, apart from the controlling unit called the Central Processing Unit 2. 3. 1 Features 1. 8 Bit CPU optimized for control applications 2.

One Serial communication port 2. 3. 2 Block diagram of 89C51 Fig 2. 3. 2 Block diagram of microcontroller 89C51 SERIES: 89C51 Family, TECHNOLOGY: CMOS This microcontroller had 128 bytes of RAM,4K bytes of on-chip ROM, two timers, one serial port and 4 ports(each 8-bits wide)all on single chip. At that time it was also referred to as a â€Å"system on a chip†. Th e 8051 is an 8-bit processor, meaning that the CPU can work on only 8-bits of data at time. Data larger than 8-bits has to be broken into 8-bit pieces to be processed by the CPU. The 8051 can have a maximum of 64K bytes of ROM, many manufacturers have put only 4Kbytes on chip. The P89C51 provides the following standard features: 4K bytes of Flash, 128 bytes of RAM, 32 I/O lines, two 16-bit timer/counters, five vector two-level interrupt architecture, a full duplex serial port, and on-chip oscillator and clock circuitry. In addition, the P89C51 is designed with static logic for operation down to zero frequenc and supports two software selectable power saving modes.The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt system to continue functioning. The Power-down Mode saves the RAM contents but freezes the oscillator disabling all other chip functions until the next hardware reset. 2. 3. 3 Memory organization Program Memory Figure below shows a map of the lower part of the program memory. After reset, the CPU begins execution from location 0000H. As shown in fig. , each interrupt is assigned a fixed location in program memory. The interrupt causes the CPU to jump to that location, where it executes the service routine.External Interrupt 0, for example, is assigned to location 0003H. If External Interrupt 0 is used, its service routine must begin at location 0003H. If the interrupt is not used, its service location is available as general purpose. Program memory addresses are always 16 bits wide, even though the actual amount o program memory used may be less than 64Kbytes. External program execution sacrifices two of the 8-bit ports, P0 and P2, to the function of addressing the program memory. [pic] Fig 2. 3. 3 Program Memory 2. 3. 4 Pin diagram of 89C51 [pic] Fig 2. 3. 4 Pin Diagram of AT89C51 2. . 5 Pin description Vcc Pin 40 provides supply voltage to the chip. The voltage source is +5v. Gnd Pin 20 is the ground. Ports 0, 1, 2 and 3 As shown in pin diagram the four ports P0, P1, P2, and P3 each use of 8 pins making the 8-bit ports. All the ports upon Reset are configured as input, since P0-P3 have FFH on them. Port 0 Port 0 occupies a total of 8 pins (pins 32-33). It can be used for input or output. Port0 is also designated as AD0-AD7, allowing it to be used for both address and data. When connecting an 8051/31 to an external memory, port 0 provides both address and data.The 8051 multiplexes address and data through port 0 to save pins. ALE=0, it provides data D0-D7, but when ALE=1, it has address A0-A7. Therefore, ALE is used for demultiplexing address address and data with the help of a 74LS373 latch. In the 8051-based systems where there is no external memory connection, the pins of P0 must be connected externally to a 10k –ohm pull-up resistor. This is due to the fact that P0 is an Open drain, Unlike P1, P2, P3. Open drain is a term used for Mos chips in the same way that open collecto r is used for TTL chips.In many systems using the 8751, 89C51, or DS89C4x0 chips, we normally connect P0 to pull-up resistors. With external pull-up resistors connected to P0, it can be used as a simple I/O port, just like P1 and P2. In contrast to Port 0, ports p1, p2, and p3 do not need any pull-up resistors since they already have pull-up resistors internally. Upon reset, ports p1, p2, ad p3 are configured as input ports. Port 1 Port 1 occupies a total of 8-pins (pins1-8). It can be used as input or output. In contrast to port 0, this port does not need any pull-up resistors since it already has pull-up resistors internally.Upon reset, port1 is configured as an input port. Port 2 Port 2 occupies a total 8 pins (pins 21-28). It can be used as input or output. However, in 8031-based systems, port2 is also designatedas A8-A15, indicating its dual function. Since an 8051/31 is capable of accessing 64K bytes of external memory, it needs a path for the 16 bits of the address. While P0 provides the lower 8 bits via A0-A7, it is the job of p2 is used for the upper 8 bits of the 16-bit address, and it cannot be used for I/O. Just like P1, port 2 does not need any pull-up resistors since it already has pull-up resistors internally.Upon reset, port2 is configured as an input port. Port 3 Port 3 occupies a total of 8 pins (pins 10-17). It can be used as input or output. P3 does not need any pull-up resistors, just as P1 and P2 did not. Although Port 3 is configured as an input port upon reset, this is not the way it is most commonly used. Port 3 has the additional function of providing some extremely important signals such as interrupts. The below table provides these alternate functions of P3. This is information applies to both 8051 and 8031 chips. Port 3 also receives some control signals for Flash programming and verification. RSTReset input. A high on this pin for two machine cycles while the oscillator is running resets the device. ALE/PROG Prior to each reading from external memory, the microcontroller will set the lower address byte (A0-A7) on P0 and immediately after that activates the output ALE. Upon receiving signal from the ALE pin, the external register (74HCT373 or 74HCT375 circuit is usually embedded) memorizes the state of P0 and uses it as an address for memory chip. In the second part of the microcontroller’s machine cycle, a signal on this pin stops being emitted and P0 is used now for data transmission (Data Bus). In his way, by means of only one additional (and cheap) integrated circuit, data multiplexing from the port is performed. This port at the same time used for data and address transmission. PSEN Program Store Enable is the read strobe to external program memory. When the AT89C51 is executing code from external program memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped during each access to external data memory. EA/VPP External Access Enable (EA). EA must be strappe d to GND in order to enable the device to fetch code from external program memory locations starting at 0000H up to FFFFH.Note, however, that if lock bit 1 is programmed, EA will be internally latched on reset. EA should be strapped to VCC for internal program executions. This pin also receives the 12-volt programming enable voltage (VPP) during Flash programming, for parts that require 12-volt VPP. XTAL1 and XTAL2 The 8051 has an on-chip oscillator but requires an external clock to run it. Most often a quartz crystal oscillator is connected to inputs XTAL1 (pin19) and XTAL2 (pin18). The quartz crystal oscillator connected to XTAL1 and XTAL2 also needs two capacitors of 30pf value. One side of each capacitor is connected to the ground.It must be noted that there are various speeds of the 8051 family. Speed refers to the maximum oscillator frequency connected to XTAL. For example, a 12-MHz chip must be connected to a crystal with 12 MHz frequency of no more than 20 MHz. When the 8051 is connected to a crystal oscillator and is powered up, we can observe the frequency on the XTAL2 pin using the oscilloscope. 2. 3. 6 Timers On-chip timing/counting facility has proved the capabilities of the microcontroller for implementing the real time application. These includes pulse counting, frequency measurement, pulse width measurement, baud rate eneration, etc,. Having sufficient number of timer/counters may be a need in a certain design application. The 8051 has two timers/counters. They can be used either as timers to generate a time delay or as counters to count events happening outside the microcontroller. Let discuss how these timers are used to generate time delays and we will also discuss how they are been used as event counters. 2. 3. 7 Polling In polling the microcontroller continuously monitors the status of a given device; when the status condition is met, it performs the service .After that, it moves on to monitor the next device until each one is serviced. Al though polling can monitor the status of several devices and serve each of them as certain condition are met. 2. 3. 8 Interrupts In the interrupts method, whenever any device needs its service, the device notifies the microcontroller by sending it an interrupts signal. Upon receiving an interrupt signal, the microcontroller interrupts whatever it is doing and serves the device. The program associated with the interrupts is called the interrupt service routine (ISR). or interrupt handler.Six Interrupts in the 8051: 1. In reality, only five interrupts are available to the user in the 8051, but many manufacturers’ data sheets state that there are six interrupts since they include reset . the six interrupts in the 8051 are allocated as above. 2. Reset. When the reset pin is activated, the 8051 jumps to address location 0000. this is the power-up reset. 3. Two interrupts are set aside for the timers: one for Timer 0 and one for Timer 1. Memory location 000BH and 001BH in the inter rupt vector table belong to Timer 0 and Timer 1, respectively. 4.Two interrupts are set aside for hardware external harder interrupts. Pin number 5. 12(P3. 2) and 13(P3. 3) in port 3 are for the external hardware interrupts INT0 and INT1,respectively. These external interrupts are also referred to as EX1 and EX2. Memory location 0003H and 0013H in the interrupt vector table are assigned to INT0 and INT1, respectively. 6. Serial communication has a single interrupt that belongs to both receive and transmit. The interrupt vector table location 0023H belongs to this interrupt. 2. 3. 9 Registers In the CPU, registers are used to store information temporarily.That information could be a byte of data to be processed, or an address pointing to the data to be fetched. The vast majority of 8051 registers are 8–bit registers. In the 8051 there is only one data type: 8bits. The 8bits of a register are should in the diagram from the MSB (most significant bit) D7 to the LSB (least signifi cant bit) D0. With an 8-bit data type, any data larger than 8bits must be broken into 8-bit chunks before it is processed. Since there are a large number of registers in the 8051, we will concentrate on some of the widely used general-purpose registers. D7 |D6 |D5 |D4 |D3 |D2 |D1 |D0 | The most widely used registers of the 8051 are A(accumulator), B, R0, R1, R2, R3, R4, R5, R6, R7, DPTR(data pointer), and PC(program counter). All of the above registers are 8-bits, except DPTR and the program counter. The accumulator, register A, is used for all arithmetic and logic instructions. 2. 3. 10 Serial communication Computers can transfer data in two ways: parallel and serial.In parallel data transfers, often 8 or more lines (wire conductors) are used to transfer data to a device that is only a few feet away. Examples of parallel transfers are printers and hard disks; each uses cables with many wire strips. Although in such cases a lot of data can be transferred in a short amount of time by using many wires in parallel, the distance cannot be great. To transfer to a device located many meters away, the serial method is used. In serial communication, the data is sent one bit at a time, in contrast to parallel communication, in which the data is sent a byte or more at a time.Serial communication of the 8051 is the topic of this chapter. The 8051 has serial communication capability built into it, there by making possible fast data transfer using only a few wires. Serial data communication uses two methods, asynchronous and synchronous. The synchronous method transfers a block of data at a time, while the asynchronous method transfers a single byte at a time. The 8051 transfers and receives data serially at many different baud rates. The baud rate in the 8051 is programmable. This is done with the help of Timer1. The 8051 divides the crystal frequency by 12 to get the machine cycle frequency.The 8051’s serial communication UART circuitry divides the machine cycle f requency of 921. 6 kHz divided by 32 once more before it is used by Timer 1 to set the Baud rate. SBUF register SBUF is an 8-bit register used solely for serial communication in the 8051. For a byte of data to be transferred via the TXD line, it must be placed in the SBUF register. Similarly, SBUF holds the byte of data when it is received by the 8051’s RXD line. SBUF can be accessed like any other register in the 8051. The moment a byte is written into SBUF, it is framed with the start and stop bits and transferred serially via the TXD pin.Similarly, when the bits are received serially via RXD, the 8051 defames it by eliminating the stop and start bits, making a byte out of the data received, and then placing it in the SBUF. SCON (serial control) register The SCON register is an 8-bit register used to program the start bit, stop bit, and data bits of data framing, among other things. Transmit In mode0 the data transmission in form of pulse train automatically starts on the p in RXD at the moment the data has been written to the SBUF register. In fact, this process starts after any instruction being performed on this register.Upon all 8 bits have been sent, the bit TI in the SCON register is automatically set. In mode1 a sequence for data transmission via serial communication is automatically started upon the data has been written to the SBUF register. End of 1 byte transmission is indicated by setting the TI bit in the SCON register. In mode2 TI (transmit interrupt) is bit D1 of the SCON register. This is an extremely important flag bit in the SCON register. When the 8051 finishes the transfer of the 8-bit character, it raises the TI flag to indicate that it is ready to transfer another byte.The TI bit is raised at the beginning of the stop bit. Receive In mode0 data receiving starts through the pin RXD once two necessary conditions are met: bit REN=1 and RI=0 (both bits reside in the SCON register). Upon 8 bits have been received, the bit RI (register SCON) is automatically set, which indicates that one byte is received. In mode1 data receiving starts as soon as the START bit (logic zero (0)) appears on the pin RXD. The condition is that bit REN=1and bit RI=0. Both of them are stored in the SCON register. The RI bit is automatically set upon receiving has been completed.In mode2 RI (receive interrupt) is the D0 of the SCON register. This is another extremely important flag bit in the SCON register. When the 8051 receives data serially via RXD, it gets rid of the start and stop bits and places the byte in the SBUF register. Then it raises the RI flag bit to indicate that a byte has been received and should be picked up before it is lost. RI is raised halfway through the stop bit. 2. 4 Level Indicator Level indicator is used to indicate the different water levels in the dams. Liquid level indicator is used to indicate the water present at what level.Here we are considering three level Low level . Medium level and High level, as the liquid level increases a message is sent to the concern person regard level of water. The main purpose of this level indicator is it checks the water level and gives the input information to micro controller. 2. 5 MAX 232 The MAX232 from Maxim was the first IC which in one package contains the necessary drivers (two) and receivers (also two), to adapt the RS-232 signal voltage levels to TTL logic. It became popular, because it just needs one voltage (+5V) and generates the necessary RS-232 voltage levels (approx. 10V and +10V) internally. This greatly simplified the design of circuitry. Circuitry designers no longer need to design and build a power supply with three voltages (e. g. -12V, +5V, and +12V), but could just provide one +5V power supply, e. g. with the help of a simple 78Ãâ€"05 voltage converter. The MAX232 has a successor, the MAX232A. The ICs are almost identical, however, the MAX232A is much more often used (and easier to get) than the original MAX232, and the MAX232A only needs external capacitors 1/10th the capacity of what the original MAX232 needs.It should be noted that the MAX 232(A) is just a driver/receiver. It does not generate the necessary RS-232 sequence of marks and spaces with the right timing, it does not decode the RS-232 signal, and it does not provide a serial/parallel conversion. â€Å"All it does is to convert signal voltage levels†. The MAX 232(A) has two receivers (converts from RS-232 to TTL voltage levels) and two drivers (converts from TTL logic to RS-232 voltage levels). This means only two of the RS-232 signals can be converted in each direction. The old MC1488/1498 combo provided four drivers and receivers.The MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply EIA-232 voltage levels from a single 5-V supply. Each receiver converts EIA-232 inputs to 5-V TTL/CMOS levels. These receivers have a typical threshold of 1. 3 V and a typical hysteresis of 0. 5 V, and can accept  ±3 0-V inputs. Each driver converts TTL/CMOS input levels into EIA-232 levels. The RS232 standard is not TTL compatible; therefore, it requires a line driver such as the MAX232 chip to convert RS232 voltage levels to TTL levels, and vice versa.The interfacing of 8051 with RS232 connectors via the MAX232 chip is the main topic. The 8051 has two pins that are used specifically for transferring and receiving data serially. These two pins are called TXD and RXD and a part of the port 3 group (P3. 0 and P3. 1). Pin 11 of the 8051 is assigned to TXD and pin 10 is designated as RXD. These pins are TTL compatible; therefore, they require a line driver to make them RS232 compatible. One such line driver is the MAX232 chip. [pic] Fig 2. 5 8051 connection to RS232 MAX232 converts from RS232 voltage levels to TTL voltage levels, and vice versa.One advantage of the MAX232 chip is that it uses a +5V power source which, is the same as the source voltage for the 8051. In the other words, with a single +5V power supply we can power both the 8051 and MAX232, with no need for the power supplies that are common in many older systems. The MAX232 has two sets of line drivers for transferring and receiving data. The line drivers used for TXD are called T1 and T2, while the line drivers for RXD are designated as R1 and R2. In many applications only one of each is used. 2. 6 GSM (Global system for mobile communication) ModemA modem (modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. A GSM modem is a specialized type of modem which accepts a SIM card, and operates over a subscription to a mobile operator, just like a mobile phone. From the mobile operator perspective, a GSM modem looks just like a mobile phone. A GSM modem can be an external modem device, such as the Wavecom FASTRACK Modem.Insert a GSM SIM card into this modem, and connect the modem to an available serial port on your computer. A GSM modem can be a PC Card installed in a notebook computer, such as the Nokia Card Phone. A GSM modem could also be a standard GSM mobile phone with the appropriate cable and software driver to connect to a serial port on your computer. Phones such as the Nokia 7110 with a DLR-3 cable, or various Ericsson phones, are often used for this purpose. A dedicated GSM modem (external or PC Card) is usually preferable to a GSM mobile phone.This is because of some compatibility issues that can exist with mobile phones. For example, if you wish to be able to receive inbound MMS messages with your gateway, and you are using a mobile phone as your modem, you must utilize a mobile phone that does not support WAP push or MMS. This is because the mobile phone automatically processes these messages, without forwarding them via the modem inte rface. Similarly some mobile phones will not allow you to correctly receive SMS text messages longer than 160 bytes (known as â€Å"concatenated SMS† or â€Å"long SMS†).This is because these long messages are actually sent as separate SMS messages, and the phone attempts to reassemble the message before forwarding via the modem interface. (We’ve observed this latter problem utilizing the Ericsson R380, while it does not appear to be a problem with many other Ericsson models. ) When you install your GSM modem, or connect your GSM mobile phone to the computer, be sure to install the appropriate Windows modem driver from the device manufacturer. To simplify configuration, the Now SMS/MMS Gateway will communicate with the device via this driver.An additional benefit of utilizing this driver is that you can use Windows diagnostics to ensure that the modem is communicating properly with the computer. The Now SMS/MMS gateway can simultaneously support multiple modems, provided that your computer hardware has the available communications port resources. 2. 6. 1 Architecture of GSM network A GSM network is composed of several functional entities, whose functions and interfaces are specified. Figure 1 shows the layout of a generic GSM network. The GSM network can be divided into three broad parts. The Mobile Station is carried by the subscriber.The Base Station Subsystem controls the radio link with the Mobile Station. The Network Subsystem, the main part of which is the Mobile services Switching Center (MSC), performs the switching of calls between the mobile users, and between mobile and fixed network users. The MSC also handles the mobility management operations. Not shown are the Operations A GSM network is composed of several functional entities, whose functions and interfaces are specified. Figure shows the layout of a generic GSM network. The GSM network can be divided into three broad parts.Subscriber carries the Mobile Station. The Base St ation Subsystem controls the radio link with the Mobile Station. The Network Subsystem, the main part of which is the Mobile services Switching Center (MSC), performs the switching of calls between the mobile users, and between mobile and fixed network users. The MSC also handles the mobility management operations. Not shown is the Operations intendance Center, which oversees the proper operation and setup of the network. The Mobile Station and the Base Station Subsystem communicate across the Um interface, also known as the air interface or radio link.The Base Station Subsystem communicates with the Mobile services Switching Center across the A interface. [pic] Fig 2. 6. 1 General architecture of a GSM network Mobile Station: The mobile station (MS) consists of the mobile equipment (the terminal) and a smart card called the Subscriber Identity Module (SIM). The SIM provides personal mobility, so that the user can have access to subscribed services irrespective of a specific termina l. By inserting the SIM card into another GSM terminal, the user is able to receive calls at that terminal, make calls from that terminal, and receive other subscribed services.The mobile equipment is uniquely identified by the International Mobile Equipment Identity (IMEI). The SIM card contains the International Mobile Subscriber Identity (IMSI) used to identify the subscriber to the system, a secret key for authentication, and other information. The IMEI and the IMSI are independent, thereby allowing personal mobility. The SIM card may be protected against unauthorized use by a password or personal identity number. Base Station Subsystem: The Base Station Subsystem is composed of two parts, the Base Transceiver Station (BTS) and the Base Station Controller (BSC).These communicate across the standardized Abis interface, allowing (as in the rest of the system) operation between components made by different suppliers. The Base Transceiver Station houses the radio transceivers that d efine a cell and handles the radio-link protocols with the Mobile Station. In a large urban area, there will potentially be a large number of BTSs deployed, thus the requirements for a BTS are ruggedness, reliability, portability, and minimum cost. The Base Station Controller manages the radio resources for one or more BTSs. It handles radio-channel setup, frequency hopping, and handovers, as described below.The BSC is the connection between the mobile station and the Mobile service Switching Center (MSC). Network Subsystem The central component of the Network Subsystem is the Mobile services Switching Center (MSC). It acts like a normal switching node of the PSTN or ISDN, and additionally provides all the functionality needed to handle a mobile subscriber, such as registration, authentication, location updating, handovers, and call routing to a roaming subscriber. These services are provided in conjunction with several functional entities, which together form the Network Subsystem. The MSC provides the connection to the fixed networks (such as the PSTN or ISDN). Signalling between functional entities in the Network Subsystem uses Signalling System Number 7 (SS7), used for trunk signalling in ISDN and widely used in current public networks. The Home Location Register (HLR) and Visitor Location Register (VLR), together with the MSC, provide the call-routing and roaming capabilities of GSM. The HLR contains all the administrative information of each subscriber registered in the corresponding GSM network, along with the current location of the mobile.The location of the mobile is typically in the form of the signaling address of the VLR associated with the mobile as a distributed database station. The actual routing procedure will be described later. There is logically one HLR per GSM network, although it may be implemented The Visitor Location Register (VLR) contains selected administrative information from the HLR, necessary for call control and provision of the subscribed services, for each mobile currently located in the geographical area controlled by the VLR.Although each functional entity can be implemented as an independent unit, all manufacturers of switching equipment to date implement the VLR together with the MSC, so that the geographical area controlled by the MSC corresponds to that controlled by the VLR, thus simplifying the signalling required. Note that the MSC contains no information about particular mobile stations — this information is stored in the location registers. The other two registers are used for authentication and security purposes.The Equipment Identity Register (EIR) is a database that contains a list of all valid mobile equipment on the network, where each mobile station is identified by its International Mobile Equipment Identity (IMEI). An IMEI is marked as invalid if it has been reported stolen or is not type approved. The Authentication Center (AuC) is a protected database that stores a copy of the secret key stored in each subscriber's SIM card, which is used for authentication and encryption over the radio channel. 2. 6. 2 Smart modem(GSM/GPRS)Analogic’s GSM Smart Modem is a multi-functional, ready to use, rugged and versatile modem that can be embedded or plugged into any application. The Smart Modem can be customized to various applications by using the standard AT commands. The modem is fully type-approved and can directly be integrated into your projects with any or all the features of Voice, Data, Fax, SMS, and Internet etc. Smart Modem kit contains the following items: 1. Analogic’s GSM/GPRS Smart Modem 2. SMPS based power supply adapter. 3. 3 dBi antenna with cable (optional: other types) 4. Data cable (RS232) 5. User ManualTemperature Range: Operating temperature: from -200C to +550C Storage temperature: from -250C to +700C Installing the modem: To install the modem, plug the device on to the supplied SMPS Adapter. For Automotive applications fix the m odem permanently using the mounting slots (optional as per your requirement dimensions). Inserting/ Removing the SIM Card: To insert or Remove the SIM Card, it is necessary to press the SIM holder ejector button with Sharp edged object like a pen or a needle. With this, the SIM holder comes out a little, then pulls it out and insert or remove the SIM Card [pic]Fig 2. 6. 2 Inserting/Removing the sim card into the modem Make sure that the ejector is pushed out completely before accessing the SIM Card holder do not remove the SIM card holder by force or tamper it (it may permanently damage). Place the SIM Card Properly as per the direction of the installation. It is very important that the SIM is placed in the right direction for its proper working condition. Connecting External Antenna Connect GSM Smart Modem to the external antenna with cable end with SMA male. The Frequency of the antenna may be GSM 900/1800 MHz.The antenna may be (0 dbi, 3 dbi or short length L-type antenna) as per the field conditions and signal conditions. DC Supply Connection The Modem will automatically turn ON when connection is given to it. The following is the Power Supply Requirement: Connecting Modem to external devices: RS232 can be used to connect to the external device through the D-SUB/ USB (for USB model only) device that is provided in the modem. 2. 7 LCD (Liquid crystal display) Liquid crystal displays (LCDs) have materials, which combine the properties of both liquids and crystals.Rather than having a melting point, they have a temperature range within which the molecules are almost as mobile as they would be in a liquid, but are grouped together in an ordered form similar to a crystal. An LCD consists of two glass panels, with the liquid crystal material sand witched in between them. The inner surface of the glass plates are coated with transparent electrodes which define the character, symbols or patterns to be displayed polymeric layers are present in between the electrode s and the liquid crystal, which makes the liquid crystal molecules to maintain a defined orientation angle.When the LCD is in the off state, light rays are rotated by the two polarisers and the liquid crystal, such that the light rays come out of the LCD without any orientation, and hence the LCD appears transparent. When sufficient voltage is applied to the electrodes, the liquid crystal molecules would be aligned in a specific direction. The light rays passing through the LCD would be rotated by the polarisers, which would result in activating/ highlighting the desired characters. The LCD does don’t generate light and so light is needed to read the display. By using backlighting, reading is possible in the dark.The LCD’s have long life and a wide operating temperature range. 2. 7. 1 Pin description of LCD: [pic] VCC, VSS and VEE: While VCC and VSS provide +5V and ground respectively, VEE is used for controlling LCD contrast. The three control lines are referred to as EN, RS, and RW. EN: The EN line is called â€Å"Enable†. This control line is used to tell the LCD that you are sending it data. To send data to the LCD, your program should first set this line high (1) and then set the other two control lines and/or put data on the data bus. RS: The RS line is the â€Å"Register Select† line.When RS is low (0), the data is to be treated as a command or special instruction. When RS is high (1), the data that is sent is a text data which should be displayed on the screen. RW: The RW line is the â€Å"Read/Write† control line. When RW is low (0), the information on the data bus is being written to the LCD. When RW is high (1), the program is effectively querying (or reading) the LCD. Only one instruction (â€Å"Get LCD status†) is a read command. All others are write commands, so RW will almost be low. 2. 7. 2 LCD Interfacing Sending commands and data to LCDs with a time delay: [pic] Fig 2. 6. Interfacing of LCD to a micro controller To send any command from command list to the LCD, make pin RS=0. For data, make RS=1. Then sends a high –to-low pulse to the E pin to enable the internal latch of the LCD. 2. 8 Control System The controlling is done through the motors. Here relays acts as motors. A  relay  is an  electrically  operated  switch. Many relays use an electromagnet to operate a switching mechanism, but other operating principles are also used. Relays find applications where it is necessary to control a circuit by a low-power signal, or where several circuits must be controlled by one signal.The first relays were used in long distance telegraph circuits, repeating the signal coming in from one circuit and re-transmitting it to another. Since relays are  switches, the terminology applied to switches is also applied to relays. A relay will switch one or more  poles, each of whose contacts can be  thrown by energizing the coil in one of three ways: 1. Normally-open (NO) con tacts connect the circuit when the relay is activated; the circuit is disconnected when the relay is inactive. It is also called a  Form A contact or â€Å"make† contact. 2.Normally-closed (NC) contacts disconnect the circuit when the relay is activated; the circuit is connected when the relay is inactive. It is also called a  Form B contact or â€Å"break† contact. 3. Change-over (CO), or double-throw (DT), contacts control two circuits: one normally-open contact and one normally-closed contact with a common terminal. It is also called a  Form C  contact or â€Å"transfer† contact (â€Å"break before make†). If this type of contact utilizes â€Å"make before break† functionality, then it is called a  Form D  contact. The following designations are commonly encountered:SPST  Ã¢â‚¬â€œ Single Pole Single Throw. These have two terminals which can be connected or disconnected. Including two for the coil, such a relay has four terminals in total. It is ambiguous whether the pole is normally open or normally closed. The terminology â€Å"SPNO† and â€Å"SPNC† is sometimes used to resolve the ambiguity. SPDT  Ã¢â‚¬â€œ Single Pole Double Throw. A common terminal connects to either of two others. Including two for the coil, such a relay has five terminals in total. DPST  Ã¢â‚¬â€œ Double Pole Single Throw. These have two pairs of terminals. Equivalent to two SPST switches or relays actuated by a single coil.Including two for the coil, such a relay has six terminals in total. The poles may be Form A or Form B (or one of each). DPDT  Ã¢â‚¬â€œ Double Pole Double Throw. These have two rows of change-over terminals. Equivalent to two SPDT switches or relays actuated by a single coil. Such a relay has eight terminals, including the coil. Here in this project we are using single pole single throw. The relay has 3 pins, 1st pin is connected to the input, 2nd pin to the output and 3rd pin is connected to the gr ound. When input is given magnetic flux is generated and the motor starts rotating and the gate will be opened according to the development.A  motor receives power through two or more relays connected to a power source. A switch-operated logic circuit is powered by a relay power source and connects to the relays. To start the motor, the switch is pressed, causing the logic circuit to close the relays sequentially. When all the relays are closed, the motor will start. If the motor starts before the logic circuit closes all of the relays, the motor is stopped and an indication is provided that the relays that have not yet been closed have failed. Otherwise, the motor runs until the switch is pressed again, causing the logic circuit to open the relays and stop the motor.A power relay is a switch that uses an  electromagnet  to open or close a circuit. The basic design of a relay utilizes an electromagnet coil, an armature, a spring and one or more contacts. If the power relay is designed to normally be open, the circuit is not completed when in the off state. As power is applied to the power relay, generally from a battery source, the electromagnet attracts the armature, a movable arm often made of iron. The armature, which was held in place by the spring, is pulled in the direction of the coil until it reaches a contact, thus closing the circuit.If the relay is normally closed, then the coil pulls the armature away from the contact, opening the circuit. A power relay can be operated using a low amount of voltage but can also conduct a higher amount of voltage. In our project we are using a sub image able motor that is nothing but a motor. When a motor starts, the phase controller applies power to the windings so that they become magnetized with the polarity that attracts the permenant magnets on the rotor; this causes the rotor to begin rotating.As the permanent magnets on the rotor rotate past the electro-magnetic windings the phase controller reverses th e polarity on the winding so that the winding repels the permanent magnets on the rotor. As the motor runs, the phase controller keeps switching windings on so that they are always attracting the permanent magnets on the rotor then repelling the permanent magnets on the rotor; this keeps it rotating. CHAPTER 3 SCHEMATIC DIAGRAM Fig 3 Schematic Diagram 3. 1 Circuit description This section gives an overview of the whole circuitry and hardware involved in the project. The required operating voltage for Microcontroller 89C51 is 5V.Hence the 5V D. C. power supply is needed by the same. This regulated 5V is generated by stepping down the voltage from 230V to 12V using step down transformer. Now the step downed a. c voltage is being rectified by the Bridge Rectifier using 1N4007 diodes. The rectified a. c voltage is now filtered using a ‘RC’ filter. Now the rectified, filtered D. C. voltage is fed to the Voltage Regulator. This voltage regulator provides/allows us to have a R egulated constant Voltage which is of +5V. The rectified; filtered and regulated voltage is again filtered for ripples using an electrolytic capacitor 100?F. Now the output from this section is fed to 40th pin of 89c51 microcontroller to supply operating voltage. The microcontroller 89C51 with Pull up resistors at Port0 and crystal oscillator of 11. 0592 MHz crystal in conjunction with couple of 30-33pf capacitors is placed at 18th & 19th pins of 89c51 to make it work (execute) properly. Operating voltage for the GSM modem will depends on its type and an adaptor is provided with the GSM modem set itself. Here in this project various levels in dams are monitored and if they exceed the threshold values a SMS is sent through the concerned person.To perform all these activities first of all different levels should be monitor using liquid level indicators. These level indicators are placed in dam at different levels like level1, level2, level3 etc†¦ whenever if any level overflows a utomatically information is sent to the control section using GSM modem. The controlling part of the water level is also done by the controller through the instructions given by the developer. In this process the controller checks the number of threshold levels that are crossed and according to that the gates are being controlled.When modem receives the message controller will communicate with the modem through serial communication. As we can not directly give the data to the controller due to the voltage level difference between the GSM modem and the controller because GSM modem works on RS 232 logic levels whereas micro controller works on TTL logic levels and also we are using PC in this project which is also a RS 232 logic based. So to have compatibility we are using MAX 232. MAX232 converts from RS232 voltage levels to TTL voltage levels, and vice versa.One advantage of the MAX232 chip is that it uses a +5V power source which, is the same as the source voltage for the 8051. In the other words, with a single +5V power supply we can power both the 8051 and MAX232, with no need for the power supplies. The MAX232 has two sets of line drivers for transferring and receiving data. The line drivers used for TXD are called T1 and T2, while the line drivers for RXD are designated as R1 and R2. By using this to TX and RX pins we are going to communicate with the controller. CHAPTER 4 FLOW CHART TX Loop: [pic] RX Loop: [pic] CHAPTER 5 SCOPE AND FUTURE ENHANCEMENTIt can be further enhanced by adding dtmf decoder to control the gate s of the dam and we send one msg to GSM amd that will be send the water level of the dam. If any unauthorized person tries to control the gate the GSM modem activate and that will pass this information to the authorized person. CHAPTER 6 CONCLUSION The project â€Å"DAM LEVEL WARNING USING GSM-SMS† has been successfully designed and tested. It has been developed by integrating features of all the hardware components used. Presence of every module has been reasoned out and placed carefully thus contributing to the best working of the unit.Secondly, using highly advanced IC’s and with the help of growing technology the project has been successfully implemented. Finally we conclude that â€Å"DAM LEVEL WARNING USING GSM-SMS† is an emerging field and there is a huge scope for research and development. CHAPTER 7 BIBILOGRAPHY 1. WWW. MITEL. DATABOOK. COM 2. WWW.

Lee CHAP TER 8 APPENDIX Source code Software used: Keil software for c programming About keil software: It is possible to create the source files in a text editor such as Notepad, run the Compiler on each C source file, specifying a list of controls, run the Assembler on each Assembler source file, specifying nother list of controls, run either the Library Manager or Linker (again specifying a list of controls) and finally running the Object-HEX Converter to convert the Linker output file to an Intel Hex File. Once that has been completed the Hex File can be downloaded to the target hardware and debugged. Alternatively KEIL can be used to create source files; automatically compile, link and covert using options set with an easy to use user interface and finally simulate or perform debugging on the hardware with access to C variables and memory. Unless you have to use the tolls on the command line, the choice is clear.KEIL Greatly simplifies the process of creating and testing an embedded app lication The user of KEIL centers on â€Å"projects†. A project is a list of all the source files required to build a single application, all the tool options which specify exactly how to build the application, and – if required – how the application should be simulated. A project contains enough information to take a set of source files and generate exactly the binary code required for the application. Because of the high degree of flexibility required from the tools, there are many options that can be set to configure the tools to operate in a specific manner.It would be tedious to have to set these options up every time the application is being built; therefore they are stored in a project file. Loading the project file into KEIL informs KEIL which source files are required, where they are, and how to configure the tools in the correct way. KEIL can then execute each tool with the correct options. It is also possible to create new projects in KEIL. Source fil es are added to the project and the tool options are set as required. The project is reloaded and the simulator or debugger started, all the desired windows are opened. KEIL project files have the extension Simulator/Debugger Coding include #include #include sbit M1 = P2^0; sbit M2 = P2^1; sbit M3 = P2^2; sbit L1 = P3^5; sbit L2 = P3^6; sbit L3 = P3^7; sbit Buz = P3^4; void TxMsg(unsigned char *msg,unsigned char *mno) { Send(â€Å"AT+CMGS=†); Send(mno); Delay_high(2); Send(msg); } void main() { bit L1_flag=0,L2_flag=0,L3_flag=0; LCD_Init(); Disp_Str(† Water Level â€Å"); LCD_Cmd(0xC0); Disp_Str(â€Å"Warning System â€Å"); M1=M2=M3=0; Buz = 1; Delay (200); SConfig(); While (1) { If (L1==0 && L2==1 && L3==1 && L1_flag==0) { L1_flag=1; L2_flag=0; L3_flag=0; Buz = 1; M1 = 1; M2 = 0; M3 = 0; LCD_Cmd (0x80); Disp_Str (â€Å"Water Level â€Å"); LCD_Cmd (0xC0);Disp_Str (â€Å"** MEDIUM **†); TxMsg (â€Å"Water Level – MEDIUM†,†9951024603†³); TxMsg (â€Å"Water Level – MEDIUM†,†9848997946†³); TxMsg (â€Å"Water Level – MEDIUM†,†9966644775†³); TxMsg (â€Å"Water Level – MEDIUM†,†9299804677†³); TxMsg (â€Å"Water Level – MEDIUM†,†9849974776†³); Delay (200); } else If (L1==0 && L2==0 && L3==1 && L2_flag==0) { L2_flag=1; L3_flag=0; L1_flag=0; Buz = 1; M1 = 1; M2 = 1; M3 = 0; LCD_Cmd (0x80); Disp_Str (â€Å"Water Level â€Å"); LCD_Cmd (0xC0); Disp_Str (â€Å"** HIGH **†); TxMsg (â€Å"Water Level – HIGH†,†9951024603†³); TxMsg (â€Å"Water Level – HIGH†,†9848997946†); TxMsg (â€Å"Water Level – HIGH†,†9966644775†³);TxMsg (â€Å"Water Level – HIGH†,†9299804677†³); TxMsg (â€Å"Water Level – HIGH†,†9849974776†³); Delay (200); } else if (L1==0 && L2==0 && L3==0 && L3_flag==0) // Level – 3 { L3_flag=1; L2_flag = 0; L1_flag=0; Buz = 0; M1 = 1; M2 = 1; M3 = 1; LCD_Cmd (0x80); Disp_Str (â€Å"Water Level â€Å"); LCD_Cmd (0xC0); Disp_Str (â€Å"** VERY HIGH **†); TxMsg (â€Å"Water Level – VERY HIGH†,†951024603†³); TxMsg (â€Å"Water Level – VERY HIGH†,†9848997946†³); TxMsg (â€Å"Water Level – VERY HIGH†,†9966644775†³); TxMsg (â€Å"Water Level – VERY HIGH†,†9299804677†³); TxMsg (â€Å"Water Level – VERY HIGH†,†9849974776†³); Delay (200); }else if(L1==1 && L2==1 && L3==1) Buz = 1; L1_flag=0; L2_flag=0; L3_flag=0; M1 = 0; M2 = 0; M3 = 0; LCD_Cmd (0x80); Disp_Str (â€Å"Water Level â€Å"); LCD_Cmd (0xC0); Disp_Str (â€Å"** NORMAL**†); } } } KIT PHOTOS OF DAM LEVEL WARNING USING GSM SMS [pic] Kit photo of dam level warning using GSM SMS ———————– GSM MODEM MAX-232 POWER SUP PLY CONTROL SYSTEM LCD LIQUID LEVEL INDICATOR Level-3 – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – — – – – – – – Level-2- – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – Level-1 – – – – – – – – – – — – – – – – – – – – – – – – – – – –  œ – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – — ———RESERVIOUR— MICRO CONTRO-LLER Tx Rx P0 P1 P2 P3 COUNTER INPUTS EXTERNAL INTERRUPTS CPU SERIAL PORT 4 I/O PORTS BUS CONTROL OSC TIMER 0 TIMER 1 ON CHIP RAM ON-CHIP RAM ON-CHIP FLASH INTERRUPT CONTROL RESET INTERRUPT LOCATIONS 8 bytes (0033)H 002BH 0023H 001BH 0013H 000BH 0003H 0000H

Reflection Activity essayEssay Writing Service

Reflection Activity essayEssay Writing Service Reflection Activity essay Reflection Activity essayIncrease in the rate of social and economic life, the growth of information, and the rise in the quality requirements of higher education objectively necessitated the high activity of the student in his daily training activities. Thus, the problem of time management is very important for me.After reading three online articles, I found that all articles are very useful for their readers because they include many time management tips, discussing almost the same things but in different words. But choosing one article, I think that the article â€Å"Time Management 101 for Online Student† is the most helpful to me. This article gave me an understanding that it is impossible to manage time, but it is possible to consider time management as â€Å"managing yourself†. This idea changed my attitude to time management and allowed me to choose more effective strategies to improve my productivity.Dwelling on the tip, taking from the articles, I would like t o create a special checklist of all things that I need to accomplish. It will help me not to hold all things to do in mind and to check them off in the period of their completion.   It seems to me that a person needs to have an independent mind for the purpose of adopting the attitude of critical thinking because only a free thinker is able not to be dependent on the opinion of other people. The next two characteristics of a great importance are open-mindedness and a natural curiosity because they will help a person to investigate various viewpoints which are different from the own and to produce the decision on the base of own attitude to the issue.Recently I have encountered some critical thinking hindrances which were based on basic human limitations. These limitations demonstrated that there are no perfect people, and human understanding of all the information, including some facts and memories, is based on existing experience. So, it is necessary to be more adequate in reacti ng on the issue at hand.To conclude, I have discussed several issues connected with time management and critical thinking, and realized that the use of some tips may improve my life and help me not only control my time, but also make some changes in reactions on ordinary things.

How to Replace a Lost Medicare Card

How to Replace a Lost Medicare Card While you might not really need to replace a lost Social Security card, as a Medicare beneficiary  your red, white, and blue Medicare card is one of the most important pieces of identification you own. Your Medicare card is proof that you are enrolled in Original Medicare and is often needed in order to receive medical services or medications covered by Medicare. Should your Medicare card be lost, stolen, damaged, or destroyed, it is important that you replace it as soon as possible. While Medicare benefits, payments, and covered services are administered by the Centers for Medicare and Medicaid Services (CMS), Medicare cards are issued and replaced by the Social Security Administration (SSA). How to Replace Your Card You can replace your Medicare card in any of the following ways: Log on to your MyMedicare.gov account and select â€Å"Replacement Medicare card.† If you have not created your MyMedicare account, its easy, secure, and a really good idea.  Request a replacement card online from the Social Security Administration. Your confidential information is completely secure, thanks to the websites state-of-the-art encryption.Call the Social Security Administration (SSA) at 1-800-772-1213 (TTY: 1-800-325-0778).Visit your area Social Security office. According to Medicare Interactive,  if  you receive  Medicare  health or drug benefits from a Medicare Advantage Plan,  such as an HMO, PPO, or PDP, you need to contact  your plan to get your plan card replaced. If you receive  Medicare through the  Railroad Retirement Board, call 877-772-5772 for a replacement  Medicare card. No matter how you order your replacement, you will need to provide some basic personal information, including your full name, Social Security number, date of birth, and phone number. Replacement Medicare cards are sent to the last mailing address you have on file with the Social Security Administration, so always notify the SSA when you move. According to the SSA, your replacement Medicare card will arrive in the mail about 30 days after you request it. If You Need Proof of Coverage Sooner If you need proof that you have Medicare sooner than 30 days, you also can request a letter which you will receive in about 10 days. If you ever need immediate proof of Medicare coverage to see a doctor or  get a prescription, you should call or visit your local Social Security office. Taking Care of Your Medicare Card: The ID Theft Threat You have probably noticed that the beneficiary identification number on your Medicare card is simply your Social Security number, plus one or two capital letters. Probably not the best idea, but that’s just the way it is. Since your Medicare card has your Social Security number on it, losing it or having it stolen could expose you to identity theft. As with your Social Security card and Social Security number, never give your Medicare ID number or Medicare card to anyone except your doctor, health care provider, or Medicare representative. If you are married, you and your spouse should have separate Medicare cards and ID numbers.   In order to have Medicare pay for your services, some doctors, pharmacies, and other health care providers may require you to bring your Medicare card with you each time you go to them. But at all other times, leave your card at home in a safe place. If you think someone is using your Medicare ID number or Social Security number you should: Create an Identity Theft Report online using the Federal Trade Commission’s (FTC) Identity Theft reporting tool. An Identity Theft Report gives you some important rights that can help you recover from the theft.Call the Federal Trade Commissions ID Theft Hotline for additional information at 1-877-438-4338 (TTY users 1-877-486-2048).
