区间ZPW-2000A轨道电路“分路不良”报警功能的设计

Design of Alarm Function of Section ZPW-2000A Track Circuit “Loss of Shunting”

基于ZPW-2000A轨道电路监测子系统平台,设计一种区间轨道电路区段"分路不良"报警功能。该报警逻辑基于实时采集的区段占用或空闲状态,能够判断出大部分区间区段"分路不良"情况。进行报警逻辑的实现及报警界面设计,在模拟测试环境下,进行多种情况下的报警测试,测试结果与预期一致。

Based on the platform of ZPW-2000A track circuit monitoring subsystem, an alarm function of section track circuit ＂loss of shunting＂ is designed. This alarm logic is able to recognize most situations of ＂loss of shunting＂ based on acquisition of the occupied/unoccupied status of sections in real time. The paper introduces the implementation of the alarm logic and the design of the alarm interface. In the simulation testing environment, the alarm function is tested in various situations and the results are consistent with the expectations.
