Method for maintaining train display system and related equipment

The invention provides a maintenance method and related equipment for a train display system, and the method comprises the steps: detecting whether a preset maintenance condition is satisfied or not in a guiding stage before a Linux system is started; and if yes, updating the first firmware target code of the train display by using a second firmware target code in an external memory. According to the technical scheme, the problem that a rail transit train display system is inconvenient to update is solved, the problem that the system cannot operate normally after the system breaks down is avoided, and the reliability, maintainability and convenience of the train display system are greatly improved. 本公开提供一种列车显示器系统的维护方法及相关设备，所述方法包括：在Linux系统启动前的引导阶段，检测是否满足预设维护条件；若是，利用外接存储器中的第二固件目标码对所述列车显示器的第一固件目标码进行更新。本公开的技术方案解决了轨道交通列车显示器系统更新不方便的问题，避免了系统故障后系统不能正常的运行的问题，极大地提升了列车显示器系统的可靠性、可维护性以及便捷性。
