The Research And Application Of Emedded Web Server Based On ARM9 And Its Communication Implement

Because of the strong needs of the supervisory control of information in the field of industry controls and the information household appliances, the embedded technology of remote supervisory control will have a broader application foreground. As the development of the embedded internet, it's convenient and cheap to transmit the information of the embedded terminals to everywhere in the world. With the technology advancement of microprocessor and computer network, there is broad attention on the network supervisory control based on embedded Web. The embedded Web Server is used in the internet, which supply the clients the share resource integration of hardware and software through visiting the Web.The basic function of network is to make webpages display in the browser by users programming and browsing. The super interlinkage in the file can guide the user to other files. As to an embedded equipment, it's more important that the super inerlinkage can connect to a CGI script, which can generate dynamic HTML webpages, so we can get the data from the sensors and transmit the data information to the remote client, such as the browser, through this mechanism, we can supervise and control them.This system is developed based on the ARM-Linux structure, the embedded Web Server uses embedded OS, establish boa web server inside. The data collection terminal transmits the sensed information to the web server. Through the network integrated structure of C/S and B/S, the users on the supervisory control sides can see the information on the the embedded Web Server directly by the browser or the special software of the supervisory control side, the authorized users can control the embedded terminals by sending instruction.
