Discussion on Processing Coding Faults Occurring in ZPW-2000A Automatic Block Section

ZPW-2000A型18信息移频自动闭塞轨道电路设备已广泛使用于我国铁路主要干线,作为指挥区间行车的重要依据,通过轨道电路传输的低频信息与机车LKJ(ATP)配套使用用于控制列车区间运行速度,提高列车运行效率,当发生区间轨道电路电码化故障时,严重干扰列车正常运行。文章就区间轨道电路发生瞬间低频信息突变造成机车信号突变故障,如何通过微机监测调看、结合电路逻辑关系分析、测试、判断,进行快速有效的故障处置提出解决办法,最大限度减少对列车运行干扰。

ZPW -2000A 18 information frequency-shift automatic block track circuit device, which has been widely used in the trunk line, is the basis of controlling train operation within the section. Low frequency information transmitted by track circuit has been interfaced with the cab LKJ （ATP） to control the section running speed of the train and therefore improve the operation efficiency. When coding faults of track circuit occurring in the section, it will seriously affect the train operation. This paper proposes fast processing solutions to sudden cab signal faults caused by transient changes of low frequency information transmitted by section track circuit, explores how to make use of microcomputer monitoring system and combine with the circuit logical relationship to analysis, test and judge so as to minimize interference to the train running.
