The invention provides a main and standby redundancy method and system for vehicle-mounted ATC equipment. The method comprises the steps that S1, state information is collected and processed; the state information comprises the state information of the vehicle-mounted ATC and the state information of activating the hot standby train line; s2, if the system is powered on for the first time, a redundant state is initialized, and otherwise, a state machine is switched; and S3, driving and activating the hot standby train line according to the state of the state machine. According to the method, the problems of deciding the activation end under the normal condition and seamlessly switching the activation end under the fault condition are solved, and the method is simple to implement and has relatively high reliability; the vehicle-mounted ATC is realized by adopting a software algorithm based on a vehicle network and an activated hot standby train line, so that the dependence on a vehicle-mounted circuit is reduced, and the default activated vehicle-mounted ATC is selected based on odd-even days or activation of a cab under a default condition; on the basis, remote or local manual forced master control can be supported, and high flexibility is achieved.
本发明提供了一种车载ATC设备的主备冗余方法及系统,包括步骤S1:采集并处理状态信息;所述状态信息包括车载ATC的状态信息和激活热备列车线状态信息;步骤S2:若系统第一次上电,则初始化冗余状态,否则转换状态机;步骤S3:根据状态机的状态驱动激活热备列车线。本发明解决了正常情况下决策激活端和故障情况下无缝切换激活端的问题,且实现简单,具有较高的可靠性;车载ATC基于车辆网络和激活热备列车线,采用软件算法实现,降低了对车载电路的依赖性,在默认情况下支持基于奇偶日或者激活司机室来选择默认激活的车载ATC;在此基础上,可以支持远程或本地人工强制主控,具有较高的灵活性。
