Design of Embedded Industrial Fieldbus Protocol Conversion and Monitor System

To solve the communication between different fieldbuses,by means of analyzing communication bus of industrial control system,the principle of the fieldbus protocol conversion is discussed.According to the basic construction of network,a scheme of fieldbus conversion is designed to accomplish the communication between different interfaces and integrate with the Internet.The embedded monitor system based on industrial control fieldbus is suitable for existing fieldbus network.The Boa Web server is configured and transplanted by using operating system of μCLinux.The corresponding dynamic CGI program of Web page is compiled and remote terminal equipments can be accessed and controlled.
