Research on Ethernet Controlled Reconnec-tion Mode of China Standard EMU

The train communication network of China standard EMU is a key facility for information exchange on the train.Compared with traditional communication methods,the Ethernet bus technology is a relatively new train communication network,featuring greater bandwidth,flexible components and low cost.Taking the China standard EMU Ethernet control as the research object,the reconnection method and position mapping of the Ethernet control,and the determination of reconnection signal are described,the train structure topology and information sharing are realized through Topology protocol,that will make the train Ethernet control technology faster,safer,more accurate and reliable.
