一起因轨道电路板引发列控中心驱采不一致报警的分析

Analysis of Train Control Center Alarm of Inconsistent State Acquisition Information and Driving Control Information Caused by Track Circuit Board

结合一次ZPW-2000轨道电路连接中断,造成列控中心对信号机驱采不一致引发的报警进行分析。主要对列控中心的设计原理、技术要求进行分析,结合维护终端数据,逐步推导,还原出故障经过,确定故障原因,并提出解决方案。

An alarm is raised by the train control center because of the inconsistency between state acquisition information and driving control information of signals caused by the interruption of communication with ZPW-2000 track circuits.This paper analyzes this alarm by examining the design principles and technical requirements of the train control center,makes inferences and restores the failure process step by step based on the data on the maintenance terminal,determines the cause of the failure,and proposes a solution.
