联锁区灰显问题的处理

Problem Processing of Interlock Zone'Gray Indication

灰显问题是指控制中心大屏不能显示运营中列车的实际位置,列车出现冲标、越站的现象,严重时造成晚点,影响乘客出行。究其原因是因中心FEP与联锁区FEP通信通道不稳定。以一个典型的故障为例,详细阐述了解决这个故障的方法和处理经过。

Grey indication means that the display panel in a traffic control center can not indicate the actual positions of trains in operation with trains overrunning the fouling post and traveling beyond destination station as well as causing delays that would affect the traveling of the passengers. The reasons of grey indication is due to the instability of the communication channels between the central FEP and the regional interlocking FEP. In this paper, a typical fault is used to elaborate the solution and treatment of such failures.
