摘要
为解决高速铁路线路故障导致列车大面积晚点或者停运的问题,并进一步完善和优化现有LKJ控车模式,通过分析我国铁路信号系统现状,提出通过400MHz无线广播方式发送基于应答器的线路数据给车载设备的普速铁路信号系统控车优化方案。基于优化方案的主要应用场景、工作机制和结构组成,提出对车载设备和地面设备的改造方法,结合我国普速铁路线路实际情况,提出工程设计改造方案,并分析方案的优势、应用前景以及经济性。普速铁路信号系统控车优化方案,实现了高速铁路动车组跨普速铁路的安全运营,以及高速铁路线路运输组织模式多样化,实现了对现有LKJ控车模式的优化升级。
To address large-scale delay or outage of trains caused by failures in high speed railway lines and further optimize the LKJ train control mode, this paper analyzed the current situation of railway signal systems in China and proposed an optimization scheme of train control for the signal system in conventional railway. The scheme is achieved by sending Balise-based line data to onboard equipment through 400 MHz wireless broadcasting. On the basis of the main application scenarios, working mechanism, and structural composition of the optimization scheme,this paper proposed methods to transform onboard equipment and ground equipment. Given the actual situation of China conventional railway, the engineering design and transformation plan was proposed, and the advantages, application prospects and economy of the program were analyzed. The optimization scheme can facilitate the safe operation of high speed railway Electrical Multiple Unit(EMU) across the conventional railway, as well as the diversification of transportation organization modes for the high speed railway line to upgrade the existing LKJ control mode.
