高速铁路ATO线路站间时间分配优化方法

Optimization Method of Time Allocation between Stations on the ATO High-Speed Railway

为了优化站间时间分配,提高高速铁路ATO线路多个车站"通过"的场景下列车运行的准点率,在阐述ATO准点运行功能的基础上,分析计划运行时间执行存在的问题,从"发车"到"停车"的整个运行区间作为整体进行考虑,将中间各"通过"车站的时刻范围作为约束条件,建立包含列车动态模型、线路数据库、ATO控制模型3部分的站间时间分配优化模型,将运行计划和线路数据等信息带入模型进行计算,获得中间各车站的优化后的"通过"计划时刻,经实验测试验证,可以使高速铁路自动驾驶列车运行更加平稳、节能、准点,为高速铁路ATO的高效运行提供保障。

In order to optimize the time distribution between stations and improve the punctuality rate of train running under the scenario of skipping multiple stations on high-speed ATO line, this article analyzes the problems existing in the implementation of planned operation time based on elaborating ATO punctual operation function, considers train originating station and parking station as a whole section and the time requirement of each skipping station as a restriction, and then sets up the optimization model of time allocation between stations, which combines with the train dynamic model, the line data and ATO control model. The information of train operation diagram and line data are brought into the model for calculation, the optimized skipping time for each station can be obtained, which makes the high-speed ATO more comfortable, energy-saving and punctual, and guarantees efficient operation for high-speed ATO.
