阐述LKJ2000型列车运行监控记录装置(以下简称监控装置)的基本工作原理。针对监控装置存在的问题,提出在轨道电路上加装点式信息装置(即地面应答器)的设计思路及具体方法。可实现车载数据校核、列车绝对定位、距离误差校正、确定列车运行方向、自动对标开车、自动进行列车侧线进路选择及支线口的列车进路选择、运行区间线路临时限速等功能。
Describes the basic working principle of LKJ2000 train operation monitoring and recording device (hereinafter referred to as monitoring device). In view of the existing problems of the monitoring device, the design idea and the concrete method of installing the point information device (ie the ground transponder) on the track circuit are proposed. It can realize the functions of on-board data checking, train absolute positioning, distance error correction, determining the running direction of the train, driving on the target automatically, selecting the route selection of the train side and the route selection of the train at the branch line, and the temporary speed limit of the operation interval line.
