The Study And Application Of Embedded Internet Technique Based On TCP/IP

The embedded equipments centered on single-chip computer have already been used largely in industrial automation, official automation and building automation etc. To realize the long distance data acquisition, control and so on,the network has already become an important trend of the development of new generation embedded system. So it has a critical realistic significance and economic value- to study the connection of embedded system and the Internet.Towards the requirement of connecting the embedded system to Internet, the paper has introduced the design scheme and special implementation of embedded Internet based on 16-bit microcontroller. After the introduction of the main solution of several kinds of the embedded Internet technology domestic and international currently, through the detailed analysis to standard TCP/IP, and combining the characteristic of the microcontroller, a method which realizes the connection of network interface card RTL8019AS of ISA and Internet based on SPCE061A is given in this paper.The paper describes the design principle of the whole system , analyzing the design of the network interface from the aspects of the software and hardware. Then it has studied the embedded TCP/IP implemented on 16-bit microcontroller. Finally, in order to prove the feasibility of the scheme, a remote data acqusition system is studied .The result has verified the design is accesible and meets the requirement.
