INTRODUCTION:
The paper aims at instantaneous transmission of the quantity of power consumed as measured by the energy meter and also sensing any misusage by the consumer. The implementation of these automated systems (communication and security alert) is realized using EMBEDDED SYSTEMS.
In EB meters there are two types, analog meters and digital meters. The analog meters are mostly used in olden days. These meter readings are calculated under the basis of the number of rotation made by the rotating disc. The digital meter is the mostly used EB meters now a day. This meter works on the basis of the flash made by the LED and according to that the reading are calculated.
In our idea we are using micro controllers namely 89C51 in both receiving and transmitting part and also in detecting faults and controlling security systems. The power measured by the energy meter is sensed using infrared sensor and given to the microcontroller for manipulation and storage purpose. The Wireless transmission is carried out using RF and FM module and thus a half Duplex means of communication.
As soon as the microcontroller in the receiver part (EB meter) gives the signal nothing but a pulse signal to the microcontroller in the USER part the microcontroller initiates the transmission of data. The data from the microcontroller is encoded by means of a Dual Tone Multiple Frequency (DTMF) encoder, and then RF modulated and then transmitted by means of a RF transmitter using the RF module. The data is received means of RF module and data is given to microcontroller. The data in the microcontroller is given to the personal computer by means of serial interface (RS232) and the data is stored in the database where the data is processed. Moreover security can be accomplished by usage of UV radiation sensors or dual camera setup. The old system tinged with the advantage of wireless communication such as excellent secured service capability without any human entanglement.
