三点检查技术对区间占用情况的分析研究

随着列车运行速度的大幅提高，当轨道电路发生故障时，若列控中心不能及时做出判断并处理，可能会使低频码序和信号机显示错误升级，从而危害行车安全。本文将联锁中“三点检查”的方法运用到区间分路状态的分析与判断中，在区间自动闭塞中引入“行车区间”的概念，从而尽可能的判断轨道电路区段分路故障。并结合相关措施进行防护，避免事故发生，保障行车安全。

Three section inspection technique to section occupancy

With the increase of train speed, and the CTCS Center couldn’t judge and treat it in time, it might cause the mistake of low frequency code sequence and signal display upgrade, thereby damaged the traffic safety. This paper took the interlock method of “The Three Section Inspection” into the analysis and judgment of section shunt state, led the concept of running interval in automatic blocking, judged the track circuit section failure as much as possible, combined with the relevant measures for the protection to avoid accident and ensure traffic safety.
