The invention relates to a redundant equipment period number synchronization method, equipment and a medium, and the method comprises the following steps: S1, enabling equipment at two ends to be redundant to each other, and initializing and maintaining the own period number from power-on according to a safety clock of a home terminal and the position of a train head where the equipment is located; s2, the period numbers used by the devices at the two ends are distributed according to the distribution principle that the ranges of the devices at the two ends are different and do not intersect, whether the messages are effective or not is distinguished according to the period numbers in the messages, and whether the messages are from or sent to the redundant end devices is judged; s3, the devices at the two ends judge the master-slave relation according to the train state information, and if the devices are confirmed to be master devices, the step S4 is executed; otherwise, executing the step S5; s4, executing a main equipment end process; and S5, executing a slave device end flow. Compared with the prior art, the method has the advantages that the overall reliability, safety and maintainability of the system are improved, and the like.

    本发明涉及一种冗余设备周期号同步方法、设备及介质,该方法包括以下步骤:步骤S1,两端设备互为冗余,从上电开始,根据本端的安全时钟和所在的列车车头位置,初始化并维护自身的周期号;步骤S2,对两端设备使用的周期号进行分配,其分配原则为两者范围不同且没有交集,并根据消息中的周期号分辨出消息是否有效以及判断消息来自或发往冗余端设备;步骤S3,两端设备依据列车状态信息来进行判断主从关系,如果设备被确认为主设备,则执行步骤S4;反之,则执行步骤S5;步骤S4,执行主设备端流程;步骤S5,执行从设备端流程。与现有技术相比,本发明具有提升了系统的整体可靠性、安全性以及可维护性等优点。
