摘要: 文章描述了列车自主运行系统中行车资源管理方法,包括行车资源的交互方法、交叠检查方法和回收方法。针对列车自主进路和自主防护时因通信延时和丢包产生的安全问题,提出了行车资源的交互方法,具有使列车直接申请并独立持有进路和进路防护区段范围上的行车资源的功能,达到了交互快、安全性高的目的。针对在行车资源交互时,因行车资源丢失而阻碍列车正常运营的问题,提出了资源回收方法,具有检查资源丢失原因并分别回收的功能,实现在丢失的资源后恢复列车正常运营的目的。针对因为同一区域行车资源同时被多列列车持有而造成列车运行安全风险的问题,提出了资源交叠检查方法,具有发现行车资源交叠以便进一步处理的功能,实现了保障列车运行安全的目的。试用结果表明,行车资源的交互方法和交叠检查方法能够保障列车运行安全;行车资源回收方法降低了行车资源在交互时丢失的风险,能够保障列车正常运营。Abstract: This paper described the interaction method, the recycling method and the overlapping inspection method of train operation resources in the Train Autonomous Circumambulation System. In view of the safety problems caused by communication delay and packet loss during train independent route and independent protection, the paper proposed an interactive method of train operation resources, which had the function of enabling the train to directly apply for and independently hold the train operation resources in the range of route and route protection section, and achieved the effect of fast interaction and high safety. Aiming at the problem of hindering the normal operation of the train due to the loss of running resources during the interaction of running resources, the paper put forward a resource recovery method, which had the function of checking the causes of resource loss and recovering them respectively, so as to achieve the purpose of restoring the normal operation of the train after the lost resources. Aiming at the problem of train operation safety risk caused by the same section of running resources being held by multiple trains at the same time, the paper proposed a resource overlapping inspection method, which had the function of finding the overlapping of running resources for further processing, and achieved the effect of ensuring train operation safety. The trial results show that the interaction method and overlapping inspection method of driving resources can ensure the train operation safety. The train operation resource recycling method can reduce the risk of loss of train resources in the interaction process and ensure the normal operation of the train.
