A Research On The Key Technology Of Embedded System Network

Along with the development of the electronics technology and the information technology, embedded system has been adopted and widely used in many fields. Internet has become one of the most important and necessary communication establishments. But embedded system is generally independent of the Internet. With the development of technology and the increase of practical demands, many kinds of embedded systems need connect to Internet to realize remote measureing, controling and information shareing. So how to connect the embedded system to Internet has become a more and more important problem.Applying Ethernet and TCP/IP technology to embedded system is called "embedded Internet technology". This thesis discusses and explores the realization and application of embedded Internet technology.This thesis analyzes the requirement of testing and controlling network in rule range. After dissecting the TCP/IP protocol based on the Ethernet developing terrace, a simplified TCP/IP protocol stack fitting for embedded system is porposed,a web server is realized on 8 bit MCU,and a feasible network scheme is porposed for testing and controlling .Data acquisition and testing controlling are realized with design the embedded web server.And successfully complete the testing of remote data acquisitiong and control with Internet.
