The invention discloses a main-standby switching method and device of a train control system, equipment and a medium, and relates to the technical field of rail transit. The method comprises the following steps: determining whether the external communication quality of a main system is lower than that of a standby system or not according to the number of first data packets sent by external equipment and received by the main and standby systems at preset time intervals; and when it is determined that the external communication quality of the main system is lower than that of the standby system, whether the communication comprehensive quality of the main system in the preset time period is lower than that of the standby system is determined according to a second data packet synchronized from the main system to the standby system, and main-standby switching is performed based on the communication comprehensive quality of the main system in the preset time period. By means of the process, the main-standby switching does not need to be carried out when the main system breaks down, when the main system does not break down, the main-standby switching can be carried out according to the advantages and disadvantages of the respective communication comprehensive performance of the main system and the standby system, and then the system performance is improved.

    本申请公开了一种列车控制系统的主备切换方法、装置、设备及介质,涉及轨道交通技术领域。该方法包括:每隔预设时段根据主备系统各自接收由外部设备发送的第一数据包数量确定主系统的外部通信质量是否低于备系统。并在确定主系统的外部通信质量低于备系统时,根据主系统向备系统同步的第二数据包确定主系统在该预设时段内的通信综合质量是否低于备系统,并基于主系统在预设时段内的通信综合质量进行主备切换。通过上述流程无需在主系统故障时才进行主备切换,当主系统无故障时可根据主备系统各自通信综合性能的优劣来进行主备切换,继而提高系统性能。
