The Research And Application Of Embedded Web Server GoAhead

With the development and application of computers and network technologies, the researchon embedded systems becomes popular globally. The embedded Web server, as part of theembedded system, plays an increasingly important role and it has become a research hotspot inthe field of embedded technologies. Most of the current network communication equipment,monitoring systems, intelligent home furnishing equipment, industrial control systems have beeninstalled with the embedded Web server. Therefore, users can directly use Web browsers tocontrol and manage the equipment.GoAhead is a Web server customized for embedded real-time operating systems. It haspowerful functions, which can meet various requirements of Web servers. In addition, it featuressmall size and high performance. It supports ASP, embedded Javascript, CGI, and SSL and alsosupports multiple operating systems and development platforms, such as the embedded Linux,QNX, Lynx, VxWorks, Windows CE. Owning to these features, many embedded devices, suchas wireless routers, use GoAhead as their Web server.Embedded Linux devices are rapidly growing in popularity, and short message service(SMS) is also widely used owning to its ease of use and reliability. To achieve better manmachine interaction, a method is proposed to add the short message function in dynamic web ofthe Linux devices that can use modems. This method allows the embedded Linux devices toreceive and transmit short messages using C-language-based CGI programming in PDU mode.Testing results confirmed the correctness, practicality, and scalability of this method.
