The invention discloses a head-tail redundancy system of vehicle-mounted signal equipment and an execution method thereof, the head-tail redundancy system is formed by connecting head-end vehicle-mounted ATP equipment and tail-end vehicle-mounted ATP equipment, the vehicle-mounted ATP equipment comprises an OBCU, a data processing unit and external equipment, the OBCU and the data processing unit are both directly connected with a communication bus, and the external equipment is connected with the data processing unit; the execution method comprises the steps that external equipment sends data to the data processing unit, the data processing unit processes the data to form a data frame and sends the data frame to the OBCU, and the OBCU receives the data frame for calculation and sends a command to the data processing unit according to a calculation result; the data processing unit converts the received command into a train signal and outputs the train signal to a train; if a certain control assembly goes wrong, the corresponding assembly is replaced, only one communication bus is adopted in the scheme, a large number of IO cables and communication cables between the two ends of the train are omitted, the cost is saved, overhauling and maintenance are more convenient, and the implementation performance is higher.

    本发明公开了一种车载信号设备的首尾冗余系统及其执行方法,首尾冗余系统由首端车载ATP设备和尾端车载ATP设备连接组成,车载ATP设备包括OBCU、数据处理单元和外部设备,OBCU和数据处理单元均直接与通信总线连接,外部设备与数据处理单元连接;执行方法为外部设备将数据发送给数据处理单元,数据处理单元处理后形成数据帧发送给OBCU,OBCU接收数据帧进行计算,根据计算结果发出命令至数据处理单元;数据处理单元将接收的命令转化为列车信号输出给列车;如有某个控制组件出现问题对应组件进行替换,本方案只采用一种通信总线,省去了列车两端之间大量的IO电缆和通信电缆,节约了成本也更便于检修和维护,实施性更强。
