Cgi Dynamic Embedded Web Server-based Design

With the rapid development of the embedded technology and network technology, how to apply Internet related technologies to the various embedded devices to replace the traditional CAN bus, RS-232 and other networking mode, so that people can use Internet technology easily to query and publish various types of information, to achieve the management and control to the embedded devices, this have become the focus attention in embedded system application field.The paper analyzed embedded Web server's software and hardware platform design detailed, analyzed Web server's network protocol and Web server's principle, used the Boa to realize embedded Web server and transplanted the Boa into the system successfully. Proposed using CGI technology to realize dynamic embedded Web server,analyzed the form called, environment variables, MIME protocol and HTML programming in CGI technology detailed, and finally designed the CGI program with C language,realized the interactive features of the dynamic Web server.The paper proposed using CGI to realize the dynamic embedded Web server, and realized it in the system platform,designed Web multiplier and the LED remote control system based on Web, the experiments' results achieved the desired design goals.Realized the user using Web browser through the Internet for real-time access control to the embedded devices and achieved dynamic Web server function's requirements.The design for dynamic embedded Web server is in line with the embedded devices and network technology's development needs and have a good theory value and broad market prospect.
