摘要
针对调度集中(CTC,Centralized Traffic Control)系统现有晚点判定模式下,无法精细掌握列车晚点状态并合理预警的问题,结合行车调度业务需求及CTC系统显示信息,设计具有可实施性的列车运行晚点状态预警机制,研究以静态线路数据元素为基本单元的晚点阈值判定技术和动态更新策略,包括针对列车类型和晚点事件发生位置的晚点时长定制计算方法,以及基于晚点事件敏感度分析的预警信息推送策略。经试验验证,该策略在晚点判定精细化和预警信息推送合理化方面具有显著优势,为晚点态势推演提供数据支撑,助力高速铁路调度业务智能化发展。
In response to the problem that the existing delay determination mode of the Centralized Traffic Control(CTC)system cannot accurately grasp the delay status of trains and issue reasonable warnings,this paper combined the train scheduling business requirements and CTC system data to design an implementable train operation delay status warning mechanism,studied the delay threshold determination technology and dynamic update strategy based on static line data elements,included customizing calculation methods for delay duration according to train type and delay event location,as well as warning information push strategies based on delay event sensitivity analysis.Through experimental verification,this strategy has significant advantages in refining delay determination and rationalizing early warning information push,provides data support for delay situation deduction and helps the intelligent development of highspeed railway dispatching business.
