站间联系电路的问题分析与改进

Problem Analysis and Improvement of Liaison Circuit Between Stations

相邻的两个铁路车站,在其间不能装设预告信号机时,可采用站间联系电路作为闭塞设备使用。主要研究计算机联锁设备与站间联系电路相结合时,采用的采集驱动电路在发生接车站计算机联锁系统重启、排列发车进路后瞬间取消该进路时,存在区间方向自动翻转与“双接近”的典型问题,对其产生的原因进行分析,并提出改进思路和具体的解决方案,为类似工程问题提供参考。

When it is not possible to install a distant signal between two adjacent railway stations,a liaison circuit between the stations can be used as a block device.This paper mainly studies the typical problems that involve the acquisition drive circuit which occur when Computer Based Interlocking(CBI)is combined with the liaison circuit between the stations,including the problem of automatic reversal of section direction when the CBI system of the receiving station restarts,and the problem of“double approaching”when a departure route is set and then immediately canceled.This paper analyzes the causes,and puts forward improvement ideas and specifi c solutions in order to provide reference for similar engineering problems.
