RBC边界轨道电路改方后信号异常关闭问题分析

Analysis of Abnormal Signal Closing After Changing Direction of Track Circuit at RBC Boundary

针对一起由于RBC边界轨道区段存在延时接收器,导致轨道电路改方后延时接收到邻区段的调谐区状态,区间出现短时间红光带,造成已开放的出站信号异常关闭的故障案例,深入分析原因,提出4种解决方案;通过对比4种方案的优缺点,为特殊问题的解决提供参考。

To deal with a fault case in which transient appearance of red light strip in section and abnormal closing of the already open starting signal resulted from the delay in receiving the state of the tuning region of the adjacent track segment after changing the direction of the track circuit due to the existence of the delay receiver at RBC boundary,the causes are investigated and analyzed thoroughly and four solutions are proposed.In the end,the advantages and disadvantages of the four solutions are compared,providing reference for the disposal of special problems.
