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.
