The invention discloses an ATO curve optimization method after train operation disturbance. The ATO curve optimization method comprises the steps of calculating the planned operation time TP of a train between stations based on a train timetable; when the train runs to a certain point Xk between stations according to the set optimal running curve and decelerates due to disturbance, counting the duration ts of train deceleration and the running time tr of the train before disturbance; calculating the shortest running time Trmin when the train runs to the station according to the maximum transport capacity at the current position Xk; judging whether Trmin is larger than or equal to TPtrts or not, and if yes, enabling the vehicle to run to the station with the maximum transport capacity at the current position; otherwise, carrying out recursive optimization at the current position with the remaining time Tr as the constraint condition, and obtaining the disturbed optimal operation curve.According to the method, a new running curve can be automatically optimized after the train is disturbed, so that the problem of delay of the train under various conditions can be well solved.
一种列车运行受扰后的ATO曲线优化方法,包括:基于列车时刻表计算列车在站间的计划运行时间TP;当列车按照既定最优运行曲线运行至站间某一点Xk处因受扰而产生减速时,统计列车减速的持续时间ts以及列车在受扰前已运行的时间tr;计算列车在当前位置Xk处按最大运力运行到站的最短运行时间Trmin;判断Trmin是否大于等于TP‑tr‑ts,如果是,在当前位置以最大运力运行到站;否则,在当前位置以剩余时间Tr为约束条件进行递推寻优,得到受扰后的最优运行曲线。本发明能在列车受扰后自动优化新的运行曲线,从而可以很好的解决列车在各种情况下的延误问题。
