Train tracking method and control system based on virtual marshalling

Abstract

According to the train tracking method and control system based on the virtual marshalling, train-to-train communication is established between a front train and a rear train, and the rear train calculates and adjusts the tracking distance between the front train and the rear train according to real-time state information such as the position and the speed of the front train; when the rear vehicle enters the semi-stable tracking state, the rear vehicle follows the front vehicle to run; and when the rear vehicle enters the stable tracking state, the rear vehicle follows the first vehicle of the virtual marshalling to run, and meanwhile, the tracking state with the front vehicle is monitored. According to the train tracking method and control system based on the virtual marshalling, the running permission of the rear train crosses the front train, the tracking interval between the front train and the rear train is greatly shortened, and the railway transportation efficiency is greatly improved on the premise that the running safety is guaranteed; the dynamic safety tracking interval is calculated according to real-time information such as positions and speeds of front and rear vehicles, and driving safety is guaranteed.

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 formation. Background technique [0002] In the existing railway blocking technology, the front and rear vehicles track and run, assuming that the front vehicle is stationary, and the driving permission of the rear vehicle extends to the rear of the front vehicle at most, and the front and rear vehicle tracking intervals include 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. Contents of the invention [0003] In view of the problems referred to above, the present invention proposes a kind of train tracking method based on virtual marshalling, and described method comprises: [0004] In th...
