采用计轴系统叠加轨道电路解决分路不良的探索与应用

Solution of Dealing with Loss of Shunting by Using Axle Counter System and Overlap Track Circuit

主要针对站内轨道电路分路不良问题进行实际分析,利用计轴技术的优点,采用计轴系统叠加轨道电路作为解决轨道电路分路不良的方案。计轴系统通过对轨道区段两端计轴检测点统计的轴数进行比较,确认区段是否空闲,并控制相应的轨道继电器、实现自动检查区段状况;同时,合理地与既有电气集中设备有机结合,彻底解决分路不良问题,最大限度地保证行车安全。

The paper analyzes mainly the problem of loss of station track circuit shunting, and presents the solution of dealing with the problem by using axle counter system and overlap track circuit. The axle counter system can detect whether the section is occupied or not by comparing the number of axles acquired at two ends of track section axle counting points, and control the relevant track relays to fulfill automatic detection of the section state. At the same time, the system can reasonably combine with the existing electric interlocking equipment to deal with the problem of loss of the shunting, so as to ensure operationsafety greatly.
