Abstract :
We can transfer data from client to Web server through GPRS communication using HTTP and TCP/IP protocols.
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 client will be our project which process basic inputs according to customer.These basic inputs are digital or analog or both. Whenever input pins are triggered then microcontroller detects these inputs and develop TCP stack with particular standard data format. Microcontroller is interfaced with 16X2 LCD which displays I/Os Information. Other end of microcontroller GSM/GPRS modem is connected serially. Through GSM/GPRS modem microcontroller sends data to server with specified IP address(Should be Static) and Port number.These IP address and Port number are related to Web server. Finally we can see data in web server from anywhere in the world.
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.
