AUTOMATIC ELECTRICAL BILLING SYSTEM TO WEBSERVER USING GPRS COMMUNICATION

AUTOMATIC ELECTRICAL BILLING SYSTEM TO WEBSERVER USING 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 updations of domestic electrical power consumption. Conventionally all homes will have sub meters to calculate power consumption. Calculations are in prices and units relation. Here microcontroller is connected to GSM/GPRS modemand 4X4 keypad.Microcontroller can calculate pricing according to units entered on4X4 keypad. User can see units and pricing on 16X2 LCD display, before sending to server.Also microcontroller prints data on thermal paper using thermal printer. User can get hard copy through paper and same data will update to web server.

This project avoids the manipulations like duplicate bills, fake bills……..etc.because at the time of billing user should submit hard copy also. It reduces manual effort and work.

            Here we use 8051 as a microcontroller with 5v DC Power supply. It’s 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. Thermal printer is based on ESC/POS commands.16X2 LCD is connected to microcontroller through Digital I/O lines.
