Abstract

The present invention provides a train control method and system based on virtual marshalling. The method includes: the following vehicle obtains the real-time state information of the preceding vehicle in real time, and the real-time state information includes the emergency braking distance; Determine the dynamic safety tracking interval with the vehicle in front with its own running state; the rear vehicle runs according to the dynamic safety tracking interval. In the train control method and system based on virtual marshalling proposed by the present invention, the following train calculates and adjusts the tracking distance of the front and rear trains according to the real-time state information of the front train, and the driving permission of the rear train surpasses the front train, which greatly shortens the tracking interval of the front and rear trains.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a train control method and system based on virtual marshalling. Background technique [0002] In the current tracking operation scenario of the front and rear vehicles of the railway block technology, it is assumed 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 an emergency braking distance and a protection distance. However, as the speed of the train becomes higher and higher, the emergency braking distance becomes longer and the tracking interval becomes larger, which affects the further improvement of the transportation efficiency. Contents of the invention [0003] For the problems referred to above, the present invention provides a kind of train control method based on virtual marshalling, comprising: ...
