GSM and GPRS based Designs have developed another innovative and Public utilityproduct for mass communication . The purpose of this project is to remote monitoring and control of the Domestic Energy meter. This system enables the Electricity Department to read the meter readings regularly without the person visiting each house. This can be achieved by the use of micro controller unit that continuously monitors and records the Energy Meter readings in its permanent (non-volatile) memory location. This system also makes use of a GSM modem for remote monitoring and control of Energy Meter.
The Microcontroller based system continuously records the readings and the live meter reading can be sent to the Electricity department on request. This system also can be used to disconnect the power supply to the house in case of non-payment of electricity bills. A dedicated GSM modem with SIM card is required for each energy meter.
The main aim of the project will be to design a SMS electronic ENERGY METER toolkit which can replace the traditional ENERGY METER. The toolkit send SMS to Electricity Department number, The system is made efficient by SIMs so that the SMS can be received by number of devices boards in a locality using techniques of time division multiple access.
The main components of the toolkit include microcontroller, GSM modem. These components are integrated with the device board and thus incorporate the wireless features. The GSM modem receives the SMS. The AT commands are serially transferred to the modem. In return the modem transmits the stored message through the wireless link. The microcontroller used in this case is ATMEL AT89S52. SIMCOM 300 is used as the GSM modem. In this prototype model, LCD display is used for simulation purpose. The results presented in the thesis support the proper functionalities and working of the system. The timing diagram suggests the response of the modem to various AT (attention) commands.
