ZPW-2000R无绝缘轨道电路红灯转移电路优化改进方案

Optimization and Improvement Scheme of Red Light Transfer Circuit of ZPW-2000R Uninsulated Track Circuit

红灯转移电路是为防止区间通过信号机红灯灭灯时,后续列车司机在未及时看到信号机显示的情况下,进入有车占用或存在危险因素的区段,从而将红灯显示转移到运行后方通过信号机上所采取的安全措施。主要以实际工程建设过程中所发现的问题为导向,通过对ZPW-2000R小轨处理方式及红灯转移电路原理的分析,说明ZPW-2000R轨道电路将红灯转移检查条件设计在发送通道上所存在的问题及电路优化方案的介绍。

The red light transfer circuit is a safety measure taken to prevent the subsequent train driver from entering the section occupied by the train or with dangerous factors when the red light of the section passing through the signal is off,so as to transfer the red light display to the rear passing signal.This paper is mainly based on the problems found in the process of actual engineering construction.Through the analysis of ZPW-2000R small rail processing mode and the principle of red light transfer circuit,it explains the problems existing in ZPW-2000R track circuit's design of red light transfer inspection conditions in the sending channel and the introduction of circuit optimization scheme.
