A New Safety System Architecture and Design for High-Speed Trains

In order to address the large amount of data interaction during high-speed train operation and the high reliability of data security, this paper designs a new type of security system based on FPGA+DSP as the main framework. The system adopts XINIF parallel interface in DSP to achieve interconnection with FPGA, which accelerates the data transmission speed. At the same time, on the base of the original double 2-vote-2, two-way redundancy system is added to improve the safety and reliability of the computer interlocking system. Analysed by simulation experiments, the new safety system has a certain degree of improvement in reliability and safety compared with the traditional double 2-vote-2 system.
