Abstract: ZPW-2000A track circuit is adopted for conventional speed railway section with small track integrated into the interlocking. When the section is not equipped with a slow release box, this paper analyzes the phenomenon of flashing red strip for the second departure section, second approach section and the boundary section of the station after the completion of the running direction change, proposes a solution to this phenomenon by the interval integrated monitoring system, and introduces specific implementation methods.

Key words: ZPW-2000A track circuit, change the running direction, red strip, QJK

摘要： 普速铁路区间采用小轨道纳入联锁的ZPW-2000A型轨道电路，当区间未设置缓放盒时，针对改变运行方向完成后的区间二离去区段、二接近区段以及本站边界区段出现的闪红光带现象进行分析，提出区间综合监控系统对于该现象的解决方式，介绍具体实现方法。
