Analysis of EMU's Network Control System and Technology

The working of EMU network control system corresponds to that of the human brain and nerves. Itplays a critical role in ensuring the EMU''ssafety, reliability, and comfort. In order to provide reference for the design of the related network control system, by analyzing CRRC''s main EMU products and extracting their common features, the key elements of the EMU''s network system have been described, such asits structure, the system function, the topological function and its main parameters.Meanwhile, the promotion of passenger demand and the continuous upgrading of rail transportation equipment technology, areputting forward higher requirements tothe EMU''s speed, comfort and intelligence.In order to clarify the development directionof EMU''s network control system, through querying the patents and literatures, the new technology research on EMU network control systemis also considered, which is focused on the multi-network convergence, the optimization designof train redundancy, train automatic driving, wireless communication and so on. This can provide reference for the design of the train''s network systemtechnical research.
