新型重载列车移动闭塞系统设计及关键技术研究

Design of New Moving Block System and Key Technologies for Heavy Haul Freight Railways

通过借鉴已有的CTCS-3级准移动闭塞系统架构和控制逻辑,结合北斗卫星导航系统在重载铁路的测试使用情况,提出一种新型重载列车信号自动控制系统方案。系统采用移动闭塞制式,并增加了ATO功能,根据列车实际运行情况和线路条件,对列车进行合理的牵引和制动、列车精确定位、远程控制重联机车等。系统实现辅助司机驾驶,能减轻司机劳动强度。当运行计划改变时或者失效时,承载ATO功能的TSRS还能及时提醒司机,将列车的实时运行状态信息反馈至地面CTC中心。目前系统已顺利通过测试,为我国重载铁路设计、产品研发提供技术参考与借鉴。

This paper drew on the existing system structure and logical structure of the CTCS-3 level quasimoving block system and proposed a new signal automatic control system for heavy haul freight railways,combined with the test application of Beidou satellite navigation system in heavy haul freight railways.The system is designed as a moving block method and added with ATO functions,which can reasonably control train traction and braking based on the actual operating conditions and line conditions of the train,accurately position the train,and remotely control the coupled locomotives.This system can assist the driver in controlling the train and reduce the labor intensity of the driver.When the operating plan changes or fails,the TSRS with ATO function can remind the driver and send real-time operating status information of the train to the ground CTC center.At present,the system has passed the test successfully,which provides a technical reference for the design and product development of heavy haul freight railways in China.
