Abstract


The prevalence of domestic manufacturing enterprises of digital devices to the coexistence of a variety of CNC systems , online programming, integrated control and other issues can not be achieved , can not be achieved with direct connectivity of enterprise management information system , resulting in a waste of site information . The development of manufacturing enterprises urgently needed as an essential source of information and basic production site data . Therefore, how to shop digital device, integrated control , integrated play and take advantage of them , many faced by the manufacturing of key technical problems and the actual production of the much-needed . The use of industrial Ethernet connected the live digital device , \This paper analyzes the advantages of industrial Ethernet applications in the field device layer , workshop digital device, communication interface and its technical characteristics of network control . EPA protocol is selected as the control system network platform , centralized control system based on Industrial Ethernet workshop digital device structure on the basis of some common industrial Ethernet protocols , the shop digital device control features for small and medium-sized enterprises , and the function of the system . To solve the serial interface of the digital devices with Industrial Ethernet communication problems , in particular digital device object to analyze the communication protocol , designed with industrial Ethernet protocol communication interface . Completed in the the PHILIP chip based on ARM core LPC2200 transplantation of embedded real-time operating system OS- II and TCP / IP protocol , on this basis, developed a protocol conversion procedures and communications test program . Analysis of the impact of co - embedded system performance factors and workshop equipment periodic and aperiodic probability distribution of the information , according to the design of embedded communication interface , the formation of experimental platform to verify the basic functions of the communication interface .
