The invention relates to a train dynamic redundancy switching system which is communicated with a train central control unit and comprises a communication module which is configured to communicate with the train central control unit and receive train data; the processor comprises a processing core, and the processing core is configured to generate verification information according to the train data; the security manager is configured to receive the verification information, judge whether the verification information is correct or not according to the verification information, and obtain judgment times and error times; calculating the quotient of the error frequency and the judgment frequency to obtain a real-time error rate; switching a redundancy mode and generating redundancy mode information according to the real-time error rate and the judgment threshold value; and the gating device is configured to control the communication module to open or close a path for transmitting the train data to the processing core according to the redundancy mode information. According to the method and the device, the problems of resource waste and working efficiency reduction of a traditional redundancy strategy in a high-speed rail control system are solved, the flexibility and the working efficiency of redundancy switching are improved, and resource waste is reduced.

    本申请涉及一种列车动态冗余切换系统,切换系统连通列车中央控制单元,包括:通讯模块,被配置为与列车中央控制单元通信,接收列车数据;处理器,包括处理核心,处理核心被配置为根据列车数据生成校验信息;安全管理器,被配置为接收校验信息,根据校验信息判断校验信息是否正确,并获取判断次数和错误次数;计算错误次数和判断次数之商,得到实时错误率;根据实时错误率和判断阈值,切换冗余模式并生成冗余模式信息;选通器,被配置为根据冗余模式信息,控制通讯模块向处理核心传输列车数据的通路开启或关闭。通过本申请,解决了在高铁控制系统中,传统冗余策略资源浪费和工作效率下降的问题,提高了冗余切换的灵活度和工作效率,减少资源浪费。
