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 customer get quantity or number of tickets issued to vehicles in web server. Also server will have the database with day wise reports also. This project is interfaced with a 16X2 LCD and a 4×4 matrix key pad. Whenever vehicle enters the toll gate, the service person enters vehicle details like license number, vehicle type, and driver name, cost/price. After completing this process microcontroller develop TCP/IP stack and sends to web server through IP address and port number.GSM/GPRS modem will do this job. From the server the owner of the vehicle will get message.

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.
