The invention discloses a train monitoring display control system and method with an automatic redundancy switching function, relates to the technical field of automatic redundancy control, and solves the problem that when a monitoring display breaks down during train operation, automatic redundancy switching of a main monitoring display system and a standby monitoring display system is difficult to realize. The technical problem that the detection safety can be improved due to the fact that a dynamic detection period is neglected during heartbeat signal detection is solved; according to the invention, hot standby redundancy is carried out on the minimum system, which is most likely to break down, of the display equipment, and when the FPGA monitors that the main control system is abnormal through the dynamic sending period of the heartbeat signal, the standby system is switched to immediately and automatically; when the main control system breaks down, the standby system is activated to take over immediately, continuous work of the monitoring displayer during train operation is ensured, and information loss or operation interruption caused by displayer faults is avoided.
本发明公开了一种自动冗余切换的列车监视显示器控制系统及方法,涉及自动冗余控制技术领域,解决了在列车运行期间监视显示器发生故障时,难以实现主备监视显示器系统的自动冗余切换,以及进行心跳信号检测时忽视了动态检测周期带来能够提高检测安全性的技术问题;本发明通过对显示器设备最容易出现故障的最小系统进行热备冗余,当FPGA通过心跳信号的动态发送周期监控到主控系统异常后,立即自动切换到备用系统;本发明能够在主控系统出现故障时,激活备用系统立即接管,确保列车运行期间监视显示器的连续工作,避免因显示器故障导致的信息丢失或操作中断。
