高速铁路列车运行冲突判定及其实现

为了提高高速铁路行车调度水平,保障行车安全,研究了车站间隔时间冲突、区间冲突、到发线运用冲突、行车作业与维修作业冲突、列车运行与旅客换乘时间冲突、动车组接续时间冲突和跨线列车跨线时间冲突7类冲突的判定方法.根据高速铁路列车运行冲突的判定依据,运用时间拓扑矩阵理论,建立了事件时间片时态关系的计算准则,实现了列车事件的时间逻辑判断.将高速铁路列车运行冲突判定分为到发线运用冲突判定和其他类型冲突判定,提出了冲突判定的思路和步骤.应用实例表明:利用上述列车运行冲突判定规则和时间拓扑矩阵模型的组合,能够实现各类列车运行冲突的实时判断,满足高速铁路行车指挥的需要. 

Judgment of Train Operation Conflict and Its Implementation for High-Speed Railway

In order to improve railway traffic control level and ensure railway operation safety,the judgment methods for 7 types of train operation conflicts were studied,including time interval conflicts between two adjacent trains at stations,conflicts of section occupation,utilization conflict of arrival and departure track,conflicts between train running and maintenance work,conflicts between train running and passenger transfer time,connecting time conflicts of electric multiple units(EMUs),and time conflicts of cross-line trains.According to the judging rules of high-speed train operation conflicts,the calculation criteria for temporal relation of event time slice was established using the theory of time topology matrix,and the time logic checking of train events was realized.The job of train operation conflict judging is divided into two parts,i.e.,the utilization conflict of arrival and departure tracks and the other types of conflicts,for high-speed rail system.In addition,the judgment methodology and processes were described.A application instance shows that the method that combines the conflict judging rules with the time topology matrix can successfully judge the various types of real-time train operation conflicts and meet the demands of high-speed railway traffic control.
