Abstract: This paper studies the technique of the Web server in the Embedded system for its application. Based on the AT91M40800 micro-controller, it presents the structures of the hardware and the software of the Embedded Web Server(EWS). It describes the design and the implementation of the EWS in detail, and also gives an example of the EWS application in the power monitoring and controlling system. Moreover, the security methods in the EWS application are discussed. The engineering practice shows that the application system with the EWS breaks through the restriction of traditional communication technique, and raises the efficiency of information usage.

Key words: embedded system, embedded Web server, micro-controller, network application
