Scene Intelligence Unit Network Interface Design And Implement The System

With the development of the technique of computer, micro—electronics ,sensor, communication and network etc.Technique of measurement and instrumentation have got great chance and infinite develop space . There are many excellent networked instruments which combine with new technology.It is networked instruments that have become the new technical trend.There are many typical applications such as remote data acquisition and controll,transferring instruments resource ,diagnosing fault and so on. In this paper ,The system of data gathering based on Ethernet will be analyzed.The first chapter summarize the network , networked measurement and networked instruments . There are some typical applications and describe some study areas and development in this chapter.In the second chapter , there will be a picture of the system about the design and realization of locale intellectualized network interface unit. And then the function ,construction and principle will be explained in detail .In the third chapter , the program of network interface , five-protocol's function and how to embed them will be introduced. At he same time , the designing and debug methods of embedding ARP, ICMP, UDP protocols will be displayed.In the forth chapter , SCOKET network programming will be simply introduced, the result of Client and Server terminal ,work flow chat about the system of the design and realization of locale intellectualized network interface unit will be gived.This chapter amply explains the program design of seven function modules ,gives all result,and writes out some problems founded and how to resolve.The fifth chapter discusses the VxCOM technology ,and introduces how to design the program of Ethernet interface VxCOM.In the last chapter , some achievements in this design will be sumed up ,and some advice about how to do this well will be gived.
