Train-ground wireless communication system of ultra-high-speed maglev train

Abstract

A train-ground wireless communication system of an ultra-high-speed maglev train comprises three communication modules: the first communication module is used for information interaction inside the train and comprises a vehicle-mounted relay station, a wireless access point, a vehicle-mounted antenna and a user terminal which form a first local area network, the vehicle-mounted relay station serves as a gateway of the local area network, collecting user information on a vehicle-mounted relay station; the second communication module is used for information interaction between the ultra-high-speed maglev train and a ground control center and comprises a vehicle-mounted relay station, a central control station, a macro station and an antenna unit which form a second local area network, and the macro station is a gateway; the third communication module is used for information interaction between the ground control center and the public switched telecommunication network and comprises a macro station and the public switched telecommunication network; the macro station performs data exchange on the information of each managed central control station and the public exchange telecommunication network; the data exchange process includes sending data of the second local area network to the wide area network and receiving data from the wide area network.

Description

technical field [0001] The invention relates to the communication field of maglev vehicles, in particular to the vehicle-ground wireless communication of ultra-high-speed maglev trains. Background technique [0002] The ultra-high-speed maglev train adopts "magnetic levitation + low vacuum pipeline", uses low vacuum environment and supersonic shape to reduce air resistance, reduces frictional resistance through magnetic levitation, and realizes supersonic "near-earth flight". The maximum theoretical operating speed can reach 4000km / h. The ultra-high-speed maglev train in the present invention refers to a train with a speed of more than 1000 km / h. [0003] In the past, the coverage of high-speed rail tunnel communication was mainly based on laying leaky cables or waveguides, but leaky cables or waveguides still have limitations. Since the ultra-high-speed maglev train runs in a low-vacuum pipeline, the pipeline and the ultra-high-speed maglev train adopt a fully enclosed c...
