Modeling of automatic control of routes on the train dispatcher plot

Abstract

This scientific article considers the methods of automatic preparation of routes at the train dispatcher's station. Currently, on the sections where trains are moving, using the high qualification of the train dispatcher and his experience in solving this problem, train routes are prepared at the stations by calculating the train schedule, that is, determining the crossing and overtaking stations. This process is modeled using a Petri net.
The process of creating routes is modeled by checking the conditions for stopping trains at the stations where they are moving. When preparing the route, the state of signaling, centralization and blocking devices, and the preparation times of train routes are taken into account. Based on the results of the calculation, the train is allowed or prohibited to leave the station. In order to send a train from the station, there should be no obstacles on the arrival of the train at the receiving station.
