Embedded Web server has very good security and stability. The embedded web server in this paper is mainly applied in control system. It is based on the feature of control system, through to the small single task Boa server on improvement to realize. Its rich hardware interfaces can be used to adaptive data acquisition device and control equipment. This paper expounds the embedded web server hardware platform and software system development, and technical support and so on. All sorts of problems are encountered, complete the solutions to design and realize the embedded web server's basic functions.
