摘要
研究目的:近年来,随着我国铁路运输网络的不断发展,350 km/h动车组需要跨普速铁路运行。350 km/h动车组只装备了CTCS-3级列控车载设备,未安装列车运行监控装置(LKJ),而普速铁路作为CTCS-0级线路,不配置CTCS-2/3级列控地面设备,导致350 km/h动车组无法在普速铁路以正常模式运行。本文从车载设备的角度出发,在分析现有技术的基础上,提出一种CTCS-3级列控车载设备融合CTCS-0控车功能的方案。研究结论:(1)方案在CTCS-3级列控车载设备的基础上,增加LKJ监控记录模块,实现CTCS-0控车功能;(2)方案不安装LKJ外围设备,由ATP主控单元为LKJ提供输入信息,不需对车辆进行改造;(3)ATP主控单元对LKJ监控记录模块的计算结果进行比较,并由ATP主控单元输出至外围设备,提高LKJ控车安全性;(4)本文研究提出了一种ATP/LKJ一体化的实现思路,可为350 km/h动车组迂回普速线路和机车装备ATP提供一定借鉴。
Research purposes: In recent years, with the continuous development of China’s railway transport network, 350 km/h EMUs need to run on general speed railways. At present, 350 km/h EMUs are only equipped with CTCS-3 on-board equipment, without train monitoring device(LKJ). However, as CTCS-0 level configuration, general speed railways are not equipped with trackside equipment of CTCS-2/3 train control system. As a result, 350 km/h EMUs cannot operate in normal mode on the existing lines. From the perspective of on-board equipment and based on the analysis of existing technologies, this paper proposes one scheme of CTCS-3 on-board equipment integrating train control function of CTCS-0 level.Research conclusions:(1)On the basis of CTCS-3 on-board equipment, LKJ monitoring and recording module is added to realize train control function of CTCS-0 level.(2)ATP master control unit provides input information for LKJ module, so LKJ peripheral equipments are not installed in the scheme, and train interface does not need to be modified.(3)ATP master control unit compares the calculated results of LKJ module, and outputs them to related peripheral equipments, so as to improve safety.(4)The research results put forward one realization idea of ATP/LKJ integration, which can provide some references for 350 km/h EMU running on general speed railway and the installation of ATP on locomotives.
