COIN BASED MOBILE CHARGER COIN BASED MOBILE.docx (Size: 433.91 KB / Downloads: 22) ABSTRACT Theobjectiveof this project is inserting the coin using charge for your mobile phonein public places. This project is very useful to people who are all using mobile phone withoutcharging condition in pubic places. In this project, who are all using mobile phones in outside of home are office without charging condition. The coin based mobile phone charger is very useful tothat person for using coin to charge for that mobile. The IR (infrared) transmitter is used to transmitIR signal in the transmitter side. The IR receiver is used to receive the IR signal in the receiver side.Between the IR transmitter and receiver, insert a coin to change the polarity of pulse in SCU input.The SCU is used to converting low pulse to high pulse and that pulse is inverted in inverter. The555 IC is act as a timer to produces high pulse for particular time period. Again the SCU is used toconverting low pulse to high pulse and this output is give to input of driver circuit. Driver circuit isused for provide the sufficient input voltage of relay. Introduction: The objective of this project is inserting the coin using chargefor your mobile phone in public places. Scope: This project is very useful to people who are all using mobilephone without charging condition in pubic places. Explanation: In this project, who are all using mobile phones in outside of home are office without charging condition. The coin based mobilephone charger is very useful to that person for using coin to charge forthat mobile. The IR (infrared) transmitter is used to transmit IR signal inthe transmitter side. The IR receiver is used to receive the IR signal inthe receiver side. Between the IR transmitter and receiver, insert a cointo change the polarity of pulse in SCU input.The SCU is used to converting low pulse to high pulse and thatpulse is inverted in inverter. The 555 IC is act as a timer to produceshigh pulse for particular time period. Again the SCU is used to converting low pulse to high pulse and this output is give to input of driver circuit. Driver circuit is used for provide the sufficient inputvoltage of relay. The relay will on to activate the 230v charger, we willuse charger to charge for our mobile phone. BLOCK DIAGRAM DESCRIPTION1.IR SENSOR AInfraRed sensor(IR sensor)is an electronic device that measuresinfrared (IR) light radiating from objects in its field of view.Apparentmotion is detected when an infrared source with one temperature, suchas a human, passes in front of an infrared source with another temperature, such as a wall.All objects emit what is known as black body radiation. It is usuallyinfrared radiation that is invisible to the human eye but can be detected by electronic devices designed for such a purpose.³Infra´ meaning below our ability to detect it visually, and ³Red´ because this color represents the lowest energy level that our eyes cansense before it becomes invisible. Thus, infrared means below theenergy level of the color red, and applies to many sources of invisibleenergy. Signal conditioning unit The signal conditioning unit accepts input signals from the analogsensors and gives a conditioned output of 0-5V DC corresponding to theentire range of each parameter. This unit also accepts the digitalsensor inputs and gives outputs in 10 bit binary with a positive logiclevel of +5V. The calibration voltages* (0, 2.5 and 5V) and the healthbits are also generated in this unit.Microcontrollers are widely used for control in power electronics. Theyprovide real time control by processing analog signals obtained fromthe system. A suitable isolation interface needs to be designed forinteraction between the control circuit and high voltage hardware. Asignal conditioning unit which provides necessary interface between ahigh power grid inverter and a low voltage controller unit. POWER SUPPLY Block diagram The ac voltage, typically 220V rms, is connected to a transformer,which steps that ac voltage down to the level of the desired dc output.A diode rectifier then provides a full-wave rectified voltage that isinitially filtered by a simple capacitor filter to produce a dc voltage. Thisresulting dc voltage usually has some ripple or ac voltage variation. A regulator circuit removes the ripples and also remains the samedc value even if the input dc voltage varies, or the load connected tothe output dc voltage changes. This voltage regulation is usuallyobtained using one of the popular voltage regulator IC units. |
