摘要
针对目前CTCS-2/3级列控系统地面设备多、系统成本高,在一些边远地区会给运营和维护带来较大困难这一难题,研发了一种基于动态间隔的列控系统。该系统的车载设备采用多源融合测速定位、线路资源申请与释放、车车无线通信、完整性检查与监控,以及全IP多模通信等多项关键技术,实现列车自主定位、移动授权计算、完整性检查等功能;有效增加车载设备的自主性,降低对地面设备的依赖;同时可缩短行车间隔,提高运营效率,为列控系统后续发展提供一定的借鉴和参考。
In response to the current problems of numerous ground equipment and high system cost in CTCS-2/3 level train control system,which may bring great difficulties to operation and maintenance in some remote areas,a train control system based on dynamic interval is studied.The on-board equipment of this system adopts multiple key technologies such as multi-source fusion speed measurement and positioning,line resource application and release,train-train wireless communication,integrity inspection and monitoring,and all-IP multimode communication to realize the functions of train autonomous positioning,mobile authorization calculation,integrity inspection etc.,effectively increasing the autonomy of on-board equipment and reducing the dependence on ground equipment.At the same time,it can shorten the running interval,improve the operation efficiency,and provide certain reference for the subsequent development of the train control system.
