Design And Implementation Of Embedded Web Server Base On DeviceNet

Nowdays, the boom of the embedded internet technology brings the ethernet in the control layer in the field of automation, even in the device layer. If you layout the embedded web server between the Devicenet and the Ethernet, you can get the remote data, and you will break out from the isolated island of the information, enlarge the space of the transmission. Therefore there is the significant practical value in the study of the embedded web server.Firstly, the paper analyses the practicality and the need in the use of the embedded web server of the Devicenet. Secondly, it brings forward the whole frame of the system, and it emphasizes the architecture of web server and the CAN interface, the realization of the driver program of Ethernet interface, with it realizes the bus communication of DeviceNet. Next, it cuts the suite of the TCP/IP protocol on the basis of the complete anatomy in the software field, and it realizes the dynamic front page with the CGI, and it carries out the web server with the help of the HTTP protocol. Lastly, the used technology on testing and providing the reference is summarized for the full-scale design in the future.
