摘要
当灾害监测系统发出预警、报警信息时,如何精准、快速、有效地执行临时限速并采取应急处置措施从而保证限速情况下列车安全、平稳、高效运行是亟待解决的关键难题。本文研究了临时限速场景下的铁路调度问题,基于轨道区段锁闭时间计算理论和铁路防灾安全监测系统的预警信息,以路网中列车的总延误时间最短为目标构建了运行图优化调整模型。通过精细化计算列车占用各个闭塞分区的时间并在调度模型基础上引入限速约束,该模型保证列车在限速场景下的安全平稳运行,从而辅助行车调度员的行车调整工作,提升应急处置能力。最后以铁岭西至扶余北段为背景设计算例并验证,表明了该调度模型的准确性。
When the disaster monitoring system issues early warning and alarm information,how to implement the temporary speed restriction(TSR)and take emergency measures accurately,quickly and effectively to ensure the safe,stable and efficient operation under TSR is a key problem to be solved urgently.In this paper,we study the railway rescheduling problem under the TSR scenario.Based on the calculation theory of the blocking time and the early warning information of the disaster monitoring system,we construct rescheduling optimization model with object of the shortest total delay time of the trains in the network.This model ensures the safe and stable operation of the train under the TSR scenario by calculating the time of the train occupying each block section refinedly and introducing the speed limit constraint on the basis of the rescheduling model,thereby assisting the dispatcher’s rescheduling work and improving the emergency response capability.Finally,a numerical example of Tieling West to the Fuyu North is designed and verified accuracy of the rescheduling model.
