Abstract: In order to solve the problems of the safety and reliability of the redundant design of the high-speed EMU network system, this research takes the factors that need to be considered in the redundant design of the “Fuxing” EMU network control system as a blueprint, and proposes the high-speed EMU network redundancy design principles, measures and methods of the control system in hardware and software. The batch application of EMUs verifies that the redundant design of the network control system is effectivein ensuring the safety, reliability and availability of the EMUs.

Key words: electric multiple unit (EMU), train control and monitor system, redundancy design
