CTCS制式下短编组列车自动折返快速停车方案研究

Quick Stop Scheme of Short Marshalling Train Automatic Turn-back under CTCS System

目前我国的动车组有4节编组、8节编组、16节编组等多种编组形式。在短编组列车进入折返线进行站后自动折返作业时,为缩短列车折返时间,应使短编组列车尽快停车,且车尾应尽量靠近折返信号机。基于CTCS(中国列车运行控制系统)制式,从轨旁信号设备的布置、信号系统的配套修改等方面,对原设计方案提出了6个优化方案,并进行了仿真。通过对仿真结果的对比分析,推荐采用在折返线中间加分隔信号机的方案。

At present,EMU(electric multiple unit)trains have 4-car formation,8-car formation,16-car and other marshalling forms.When a short marshalling train enters the turn-back line for after station automatic turn-back operation,the train must stop as quickly as possible,and the train tail should be as close to the turn-back signal as possible in order to shorten the turn-back time.Based on CTCS(China train control system),six optimization schemes are proposed and simulated for the original design scheme from the trackside signal equipment layout and the signal system modification.Through a comparative analysis of the simulation results,the scheme to add separation signals in the middle of the turn-back line is recommended.
