摘要
研究目的:我国普速铁路装备CTCS-0级列控系统,它通过列车运行监控装置(LKJ)结合通用机车信号实现列车超速防护,对于保证行车安全和提高运输效率发挥了重要作用。但是,CTCS-0级列控系统是基于当时的线路状况设计的,已逐渐不能满足我国铁路发展的需要。本文通过分析CTCS-0级列控系统面临的问题及相关的改进方案,结合列控技术的最新进展,提出一种普速铁路CTCS-0级列控系统的优化方案。研究结论:(1)方案维持LKJ存储线路数据的方式,可以减少地面设备改造的工程量;(2)LKJ通过无线通信与地面服务器校核数据版本,保证线路数据的正确性;(3)方案结合应答器和北斗卫星导航系统实现列车定位,避免司机可能的错误操作;(4)本研究成果可为普速铁路列控系统的改造提供一定借鉴。
Research purposes:CTCS-0 train control system is adopted in Chinese general speed railway,which uses train monitoring device(LKJ)combined with general cab signal to realize train operation protection,which plays an important role in ensuring safety and improving efficiency.However,CTCS-0 train control system was designed based on the condition of railway at the time,which cannot meet the needs of railway development in China.By analyzing the challenges faced by CTCS-0 train control system and related improvement schemes,this paper aims to propose one optimization scheme for CTCS-0 train control system of general speed railway.Research conclusions:(1)The scheme maintains the way of LKJ storing line data,which can reduce the engineering amount of trackside equipment.(2)LKJ verifies the data version by radio communication with trackside server,which can ensure the correctness of line data.(3)The scheme combines balise and BeiDou Navigation Satellite System(BDS)to realize train positioning,which can avoid drivers possible wrong operation.(4)The research results can provide some references for upgrading train control system of general speed railway.
