The invention provides a dynamic redundancy backup method and system suitable for a train control system platform, and the method comprises the steps: executing a power-on synchronization management flow under the condition that a power-on initialization detection result is qualified, so as to determine main control equipment and a standby host of the train control system platform; on the basis ofthe system configuration information and the configuration information of each board card, respectively determining a mainboard corresponding to the main control equipment and a standby board corresponding to the standby host; loading a host application related to the main control equipment to the mainboard, and loading a standby application related to the host application to the standby board; and controlling the host application and the standby application to operate to enable the train control system platform to enter a dual-computer hot standby operation mode. The invention provides a setof redundant backup processing logic, and the spare board card is dynamically utilized to deploy the backup application, so that the stable and continuous operation of the host and the spare machinecan be ensured, hardware resources are integrated and utilized to the greatest extent, the design requirements on main and spare redundancy are met, and higher safety and reliability are achieved.

    本发明提供的适用于列车控制系统平台的动态冗余备份方法及系统,包括:在上电初始化检测结果合格的情况下,执行上电同步管理流程,以确定列车控制系统平台的主控设备和备用主机;基于系统配置信息以及每块板卡的配置信息,分别确定主控设备所对应的主机板,以及备用主机对应的备机板;将主控设备相关的主机应用加载至主机板,并将主机应用相关的备机应用加载至备机板;控制主机应用和备机应用运行,以使得列车控制系统平台进入至双机热备运行模式。本发明提供了一套冗余备份处理逻辑,同时动态地利用空余板卡部署备份应用,能确保主机和备机的稳定连续运行,并最大程度整合利用硬件资源,满足对于主备冗余的设计要求,具备更高的安全性和可靠性。
