摘 要:车载中心化的列控系统是面向我国西部地区低密度线路的新型列控系统。为满足该列控系统由车载设备自主实现进路控制的需求,基于车载设备控制轨旁对象控制器实现进路资源占用和释放的思想,提出一种车载中心化的列车进路控制方法。首先按照列车进路控制流程,利用有色Petri网建立进路资源征用模型,通过模型仿真分析发现多车进路过程中存在潜在的“赛跑问题”。然后根据列车进路作业原则,提出进路冲突资源分配目标函数,并基于分布式死锁预防方法和可用性检查技术,针对集中式轨旁控制器提出一种进路资源分配算法。最后利用进路资源分配算法修正进路资源征用模型。通过对修正前后模型仿真结果的分析,验证了该算法可以有效避免多车进路控制过程中的“赛跑问题”,并能提升列车进路资源征用效率。The onboard-centered train control system is a new train control system for low-density lines in remote areas of western China.In order to meet the needs of the onboard-centered train control system for the independent route control by the onboard equipment,an onboard based train route control method was proposed by using the onboard equipment to control the trackside object controller to realize the requisition and release of the route resources.According to the train route control process,the route resources requisition model was established by using the Colored Petri Nets,and the potential resource competition problem in the multi-train route control process was found out through model simulation.According to the principle of train route operation,the objective function for allocation of resources with route conflict was proposed.Based on Order-based Deadlock Prevention Protocol with Parallel and Availability Check Technique,a route resource allocation algorithm for the trackside object controller was put forward,which was used to modify the route resource requisition model.The analysis of the simulation results before and after the modification of the model has verified that the algorithm can effectively avoid the resource competition problem in the multi-train route control process and improve the efficiency of train route resources requisition.
