高速铁路CTCS-3级列控系统等级转换工程应用研究

Research on the Engineering Application of the Level Transition of CTCS-3 Train Control System in High-speed Railways

高速铁路CTCS-3列车运行控制系统等级转换是工程设计及系统集成的重要内容之一。列控系统等级转换在地面系统中设置等级转换点,由车载设备完成等级转换。等级转换位置受线路长度、转换点处速度、临时限速、分相区设置等多种因素限制,在工程应用中,地面系统需结合车载设备的控制逻辑进行综合分析。如果等级转换预告点或执行点设置不当,可能会导致列车降速运行,或者导致列车越过等级转换点时触发制动而停车。系统分析CTCS-3级列控系统等级转换的原理,尤其对车载设备在CTCS-2级、CTCS-3级控车曲线存在速度差的情况进行分析。对CTCS-3级列控系统等级转换在正线区间、大号码道岔以及并列车场等工程中的应用方案进行总结,对设置等级转换应答器的距离要求进行归纳及量化,涵盖了常见的工程应用场景。

The level transition of CTCS-3 train control system for high-speed railway is one of the significant contents of engineering design and system integration.The level transition is set in the ground system and completed by on-board equipment.The position of the level transition is restricted by some factors,including the length of the railway,the speed at the level transition border,temporary speed restriction,neutral zone and etc.In the application of engineering project,the control logic of on-board equipment should be considered and analyzed synthetically with trackside system.If the distant position or level transition border is not set properly,the running speed of the train may be reduced,and the train may be triggered to break and stop when it crosses the level transition border.This paper systematically analyzes the principle of level transition of CTCS-3 train control system.In particular,the speed differences of train control curve of CTCS-2 and CTCS-3 are studied.The application schemes of CTCS-3 train control system level transition in main line sections,large-number turnouts and transversal type yards are summarized,and the setting distance of level transition balise is concluded and quantified,covering most engineering application scenarios.
