摘要: 通过对影响列车运行状态的事件进行分析,指出各类事件对列车状态的影响本质上是改变列车的加速度。采用MLD建模理论建立了列车运行调度模 型,该模型将连续行为和离散行为统一在一个框架中并考虑了停站时间、安全距离等约束。以6站5区间的调度区段为例,对模型进行了仿真研究。针对施 加干扰后列车发生的晚点的情况,采用压缩列车停站时间和区间运行时间的方法对晚点的列车进行调整,最终列车恢复了正点运行。仿真结果证明了模型 的有效性和正确性。

Abstract: Through analyzing the events affecting train operation status,it was pointed out that the essence of the effect imposed on trains by various events was to change train’s acceleration.Using the mixed logic dynamic system theory,the train traffic control model was established,which put the continuous and discrete behaviors into a unified framework and considered the constraints,such as the minimal dwell time and safe distance.A dispatch section including 6 stations and 5 sections was used to carry out the simulation study of the proposed model.For train’s delays resulting from the imposed disturbances in simulation,the method of compressing the dwell time and the interval running time in sections was used to adjust the delayed train,which eventually restored the train’s punctual operation.The validity and correctness of the proposed model is verified by simulation results.

Key words: traffic and transportation engineering, train control, mixed logic dynamic system, simulation, adjustment
