Abstract
In the traditional project of industry control, the field operator is the only man who watches production condition at the production spot. Enterprise administers cannot obtain real-time production status and make real-time decision if they don’t reach the production spot. Because of the development of Embedded Web Server such status is being changed. The remote monitor and control mode based on Embedded Web Server provides complete exact real-time information for managers, and makes it possible to make a decision in real time. In the paper, the design and implements of Embedded Web Server are presented and the key realization technology of it is described in detail. EWS (Embedded Web Server) will effectively lower system operating cost and improve maintaining efficiency, which has wide application prospect and popularization value in industrial control systems.

Summary
With the rapid development of the computer and network technology, it has caused the technical revolution with the industrial control systems. The industrial control systems can be equipped with Web servers for providing Web-based network communication. This type of Web server is called an Embedded Web Server (EWS). In the conditions of EWS-equipped devices, the users can use web browser to manage devices and to receive and send data to browsers anywhere in the world in order to configure, monitor and control them. By the Web browsers, users can manage individual devices remotely This scheme provides a user with a simple but powerful user interface. Most embedded devices based on 8-bit microcontrollers, contain a small amount of memory, so in the design and implementation of EWS, some optimization techniques must be applied. The result of experiment proves that it is feasible to realize the target at very low costs [2]
