Title:
TRAIN GROUP CONTROL METHOD AND SYSTEM BASED ON AD-HOC NETWORK
Document Type and Number:
WIPO Patent Application WO/2022/077966
Kind Code:
A1
Abstract:
A train group control method based on an ad-hoc network, the method comprising: a train ad-hoc network device searching for communication devices of other trains within a pre-set distance; determining whether a train is on the same rail as the other trains; if so, determining whether a networking condition is met; if so, determining whether there is an ad-hoc network; if there is no ad-hoc network, the other trains meeting the networking condition establish an ad-hoc network with an original train; if there is an ad-hoc network, the other trains meeting the networking condition join the ad-hoc network; and a train group in the ad-hoc network controlling the operation of the trains in the ad-hoc network by means of the ad-hoc network. Further disclosed is a train group control system based on an ad-hoc network. By means of the control method and the control system, train group control is realized on the basis of train-to-train communication technology in an ad-hoc network. Trains perform automatic networking when conditions are met, and inter-train data is transmitted between the trains without relying on a ground base station. No central control device needs to be arranged on the ground, and wireless network coverage is not needed in a ground section. A train interval is dynamically adjusted according to line conditions, a temporary speed limit and the state of each train in a group.
