Abstract: Intelligent measurement equipments are basic and key of control network. Application of high performance embedded technology to develop intelligent measurement equipment is one of the most important trends. The author brings forward the overall design of industrial Ethernet network. It illustrates how to implement the hardware and software of the embedded equipment. Mechanism and design theory of each part is deeply analyzed. The realization of 32-bit embeds processor system, Ethernet interface model, uCLinux OS, driver under uCLinux, socket, HTTP protocol, embedded Web Server are given in detail.
