一种基于铁路调车防护系统的列车运行监控装置自动开车对标的方法

A Method of LKJ Automatic Initial Positioning Based on Locomotive Shutting Protection System

在CTCS-0区段始发站发车时,司机通过列车运行监控装置(简称"LKJ")设定参数后,若提前或滞后操作开车对标,会导致LKJ显示距离与实际距离存在误差,使列车存在信号冒进、运行超速等风险,严重影响列车运行的安全。为此,文章提出一种基于铁路调车防护系统的自动连锁对标方法,其利用预先存储的站场图数据并结合站场实时联锁状态和机车位置信息来实现LKJ自动开车对标。仿真和现场试验结果表明,采用该方法后,对标误差控制在±2‰以内,不仅可有效消除手动对标带来的安全风险,同时还降低了司机的劳动强度。

At the departure station of CTCS-0 section,after a driver sets parameters through train operation monitoring device(referred to as"LKJ"),if initial positioning is operated ahead of time or behind time,it will lead to an error between LKJ displayed distance and actual distance.The train has the risk of signal overruning and running overspeed,which seriously affects the safety of train operation.Therefore,this paper proposes an automatic interlocking initial positioning method based on the locomotive shutting protection system,which uses prestored station map data,combined with real-time interlocking status and locomotive position information to realize LKJ automatic initial positioning.Simulation and field test results show that by the proposed method,initial positioning error is controlled within±2‰,which not only can effectively eliminate the safety risk brought by manual initial positioning,but also can reduce the labor intensity of driver.
