A train tracking method and control system based on virtual marshalling

Abstract

The invention proposes a train tracking method and control system based on virtual marshalling. Vehicle-to-vehicle communication is established between the front and rear vehicles, and the rear vehicle calculates and adjusts the tracking distance of the front and rear vehicles according to real-time state information such as the position and speed of the front vehicle; In the semi-stable tracking state, it follows the vehicle in front; when the rear vehicle enters the stable tracking state, it follows the first vehicle in the virtual group, while monitoring the tracking state of the vehicle in front. With the train tracking method and control system based on virtual marshalling proposed by the present invention, the driving permit of the rear train passes over the preceding train, which greatly shortens the tracking interval of the front and rear trains, and greatly improves the railway transportation efficiency under the premise of ensuring the driving safety; The method of calculating the dynamic safety tracking interval based on real-time information such as the position and speed of the front and rear vehicles to ensure driving safety.

Description

technical field [0001] The invention belongs to the field of train control, in particular to a train tracking method and control system based on virtual marshalling. Background technique [0002] In the existing railway blocking technology, the front and rear vehicles track and run, assuming that the front vehicle is stationary, the driving permit of the rear vehicle extends to the rear of the front vehicle at most, and the tracking interval between the front and rear vehicles includes at least a braking distance and a protection distance. However, the train speed is getting higher and higher, the braking distance is getting longer and longer, and the tracking interval is getting bigger and bigger, which affects the further improvement of transportation efficiency. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention proposes a train tracking method based on virtual marshalling, the method comprising: [0004] In the train group for virtu...
