Embodiment Construction

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] In the embodiment of the present invention, multiple trains no longer use equipment such as couplers to realize physical connection, but use wireless communication methods such as vehicle-to-vehicle communication to realize virtual coupling among multiple trains. In the virtual coupling system, since the trains do not use couplers and other equipment t...

Abstract

The invention relates to a virtual coupling multi-train cooperative controlling method and system. The virtual coupling multi-train cooperative controlling method includes the steps that the acceleration of an adjacent train of a controlled train, the speed difference value between the controlled train and the adjacent train of the controlled train and the redundancy distance between the controlled train and the adjacent train of the controlled train are obtained; the acceleration of the controlled train is determined according to the acceleration of the adjacent train of the controlled train,the speed difference value between the adjacent train of the controlled train and the controlled train, and the redundancy distance between the controlled train and the adjacent train of the controlled train; the speed of the controlled train is adjusted according to the determined acceleration of the controlled train. According to the virtual coupling multi-train cooperative controlling method and system, each train is driven close to the closest front train, and the stable and coordinated operation of a train group is realized, so that the purpose of safety and high efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a multi-train cooperative control method and system using virtual coupling. Background technique [0002] In rail transit, tracking control is usually performed by blocking, that is, using signals or vouchers to ensure that the train runs according to the technical method of keeping a certain distance (spatial separation system) between the preceding train and the tracking train. In this way, the front control train is tracked according to the block partition, the tracking interval is relatively large, and the control efficiency is low due to the influence of many control levels; in addition, the two trains are managed as independent individuals, occupying a train number and a planned line respectively. The transportation capacity of a single vehicle cannot be flexibly adjusted. Although the existing line adopts the method of reconnecting trains, due to the physical connect...
