Application Of Ring Network In Computer Interlocking Control System

According to the development trend of industry control network and the communications characteristic in computer interlocking system and the characteristic of kinds of communication methods,I put forward the concept , principle and design method about ring network. And it makes computer interlocking system interchange data. According to the principle of ring network I constitute communication protocol .I designed the communication circuit, debugged it and simulated it in the light of communication principle and communication protocol of ring network on Xilinx's FPGA chip. I proved the reliability of data communication in ring network in theory, and validated real time communication according to simulation wave in ring network.
