Abstract
This paper designs a new dual-duplex safety-critical computer system used in the rail transport system including I/O module, CPU module and switch module. In the I/O module, the dynamic circuit design can make it achieve safe input and output data, hi the CPU module, this paper presents a synchronization vote program based on Ethernet communication. In the switch module, it implements seamless switch by loop control. It is shown through functional and safety test that the dual-duplex safety-critical computer system can meet the needs of computer platform with high reliability and security.
