The Principle Of Embedded Networked Instrument

It's a mature technology to realize Internet instrument in PC. However, with the development of technology and practical demand, it's necessary to realize Internet in embedded system, for example in instrument and electrical appliance, to realize remote measure, control and share information. But it's difficult to embed the complicated protocol of TCP/IP into system because of the limited resource (ROM, RAM and speed), especially in 8bit MCU. We analysis the technology of embedded internet and provide a successful application model .The whole system consists of two parts-client and server ,the server is composed of SX52> imagine model and interface circuit in hardware ,the special software realize TCP > UDP> IP, ARP protocol, and analog the bottom imagine interface. The client ,based on PC , is responsible to sending commander -. transferring data , recovering imagine etc .The system can realize internet control and imagine acquisition >. transfers and recovery .
