城市轨道交通信号系统车地无线冗余 方案探索.

- Abstract
The paper focuses on improving the stable and reliable transmission of vehicle-ground information by wireless systems, and puts forward a scheme to optimize the redundant architecture of a vehicle-ground wireless system with additional vehicle-ground transmission links. Wireless link health status monitoring and non-disturbance link switching are used to ensure that the information is always transmitted on the optimal link. The proposed scheme reduces the probability of interruptions in vehicle-ground wireless communication caused by wireless errors affecting the stable operation of trains. The stability and reliability of the signal systems of rail transit can be improved by promoting the redundancy of such wireless systems.
