The Research And Implementation Of The Thin Server Based On The Embedded Internet Technology

Internet as well as the embedded system is common now. The application of these two techniques in modern measurement&control field makes the techniques of measurement control system and the network fused well. It can not only break the attempt of monopoly from abroad manufactories, but also decrease the cost of research new products and the construction of the system. From the paper, it can be concluded that it is necessary to make many intellectual electronic equipments access the Internet in the new era with the development of the computer, communication and the network technique. With the thread of the data structure and the communication of the information, this paper designs the hardware and software of the system and implements the functions of the thin server by using the SOC SCM extended network interface chips. Moreover, the paper gives an application example of the thin server.This paper gives the conception of the network server and the thin server first Based on the comparison of several current embedded Internet technologies, this paper gives the new schemes to control the large-scale printer by using the SCM system as the thin server. In the following part of this paper illustrates the thought and method of thin server with hardware and software. It illustrates the construction &function of hardware, the driving method of Ethernet interface chip, and analyzes the construction of embedded TCP/IP protocol, the content of each protocol, and each function module and programming details with flow chartsAt the same time, a kind of graphical programming language Lab VIEW is introduced It makes network virtual devices and remote control possible.The purpose of the research work is to upbuild modern industry measurement& control network whose structure is single client and many servers The thin server is researched and designed in this work, which has better performance and wide apply foreground.
