CTCS-3级列控系统采用静态曲线与动态曲线相结合的方式监控列车的运行速度,是目前铁道部大力推广使用的列控系统。为此介绍该系统的结构组成及其速度监控的基本原理,说明静态速度监控曲线、动态速度监控曲线的分类及其关系,并结合实例提出了CTCS-3级列控系统中最低限制速度曲线,以及由最低限制速度曲线计算出各种动态曲线的方法,为CTCS-3级列控系统速度曲线的计算提供了方便。
CTCS-3 train control system uses a combination of static curve and dynamic curve to monitor the running speed of the train. It is a train control system that is widely promoted by the Ministry of Railways. This paper introduces the structure of the system and its basic principle of speed monitoring. The classification and relationship of static speed monitoring curve and dynamic speed monitoring curve are described. The minimum speed limit curve of CTCS-3 train control system is presented with examples. And the method of calculating various dynamic curves from the minimum speed curve provides convenience for calculating the speed curve of the CTCS-3 train control system.
