Title:
NETWORKING COMMUNICATION METHOD AND APPARATUS BETWEEN TRAINS, AND TRAIN CONSIST
Document Type and Number:
WIPO Patent Application WO/2024/077539
Kind Code:
A1
Abstract:
A networking communication method and apparatus between trains, and a train consist, which relate to the field of wireless backbone network communications for rail transit. The method is applied to a train consist, and comprises: sending a first topology discovery message of a present train by using preset directional antennas, and receiving first topology discovery messages of other trains that are sent by other train consists; determining a networking situation according to networking topology information in the first topology discovery messages of the other trains; and if the networking situation indicates a convergence-completed state, according to networking topology information of the present train, performing data transmission with a target node in a network by using the preset directional antennas. In the present invention, each train consist can send and receive topology discovery messages by using back-to-back directional antennas, so as to determine the positions of the other train consists relative to the present train by using the topology discovery messages received by means of the back-to-back directional antennas, thereby realizing the wireless networking of the train consists; and data transmitted between nodes is forwarded by using train nodes in a network, such that the reliability of the wireless communication between trains is improved.
