摘要
为解决广佛线地铁列车经常出现多个车门显示同时出现红点故障的问题,从车门显示控制原理、列车控制和车门通信协议等方面深入调查分析,查找故障原因。最终确认是由于软件通信协议存在缺陷,导致列车控制系统无法接收所有车门的实际状态信息,并通过修改列车控制及车门软件,实现列车MVB(多功能车辆总线)+RS485双总线冗余功能,使故障得以消除,效果显著。
The multiple door red dot faults often appear on Guangzhou-Foshan Metro Line, to solve this problem, the door control principle, train control and door communication protocols and so on are investigated in depth, to find the causes of the malfunction. Finally, flaws in the software communication protocol arc confirmed, which led to the train control system failure in receiving all the information about the actual status of doors. By modifying the train control and the door system software, the train MVB ＋ RS485 dual bus redundancy is achieved, and the fault is fundamentally solved with remarkable effect.
