Study on Application of Regional Computer Interlocking in High-Speed Railway

China is one of the leading countries in the world in the field of high-speed railway. The performance of computer interlocking system is very important for driving safety and efficiency. In recent years, in recent years, because of the speed-up of China's high-speed railway, it puts forward higher requirements for the safety and reliability of computer interlocking. This paper proposes a new regional computer interlocking system, and describe the overall structure and function design of the system, including man-machine interaction layer, interlocking operation layer and program execution layer. For redundancy design of computer interlocking software, we adopt two-times-two-take-two scheme to design input and output control software, to ensure the system security.
