REAL TIME AUTOMATIC METER READING THROUGH GPRS COMMUNICATION

REAL TIME AUTOMATIC METER READING THROUGH GPRS COMMUNICATION

ABSTRACT

Now a day’s Many real time applications connected to web(internet).This is very useful and helpful for customers to see application(requirements) from anywhere in the world. These web connected applications belong to server client model. TCP, UDP and HTTP protocols are used in this concept. Data transfer to web server is done through GPRS (General packet radio services) communication. We can transfer large amounts of data through this GPRS. Many Embedded Networking applications fall under this model only.

In this project we can get updating of domestic electrical power consumption. Conventionally all homes will havesub meters to calculate power consumption.Calculations are in prices and units relation. Here we connect energy meter to microcontroller. Microcontroller gets pulses from meter according to power consumption.For every ten units microcontroller generates one TCP stack with standard data format.Other end of microcontroller GSM/GPRS modem is connected.This modem updates TCP stack information to web server and same data updates can also be sent to any mobile. This is very useful to monitor power consumption remotely from anywhere in the world.Same data can be displayed on 16X2 LCD.

Here we use 8051 as a microcontroller with 5v DC Power supply. Its having some Basic inputs and outputs. Serial(UART) protocol is primary concern here. The main heart of this project is GSM/GPRS modem and it work on GPRS AT commands. 16X2 LCD is connected to microcontroller through Digital I/O lines.
