Problems solved by technology

[0006] (1) The train needs to establish a wireless communication connection with the next zone before the switching of the operation control zone, which increases the complexity of the zone handover process, and unstable wireless communication will increase the failure rate of zone switching
Trains need to frequently implement traction cut-off and emergency braking, which will affect the punctuality rate of the line, train op

Abstract

The invention provides a train-ground wireless communication system of a medium-high speed maglev train. The system comprises a vehicle-mounted radio system, and a partition radio control unit, a radio base station and a central radio control unit which are arranged in partitions along a track. The vehicle-mounted radio system is connected and communicated with the radio base station through 38G radio; the radio base station transmits received train signals to the partition radio control unit through an optical fiber network, the partition radio control unit transmits the received train signals to the partition safety computer, the traction control system and the central radio control unit, and train-ground information transmission is achieved. According to the system disclosed by the invention, the communication partitions and the operation control partitions are arranged in a staggered manner; the cross-partition handover of the train-ground communication and the cross-partition handover of the operation control system are executed separately, so that the operation control partition handover failure rate caused by communication connection failure is reduced, the times of tractioncut-off and emergency braking are reduced, and the line punctuality rate and the passenger comfort are improved.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a vehicle-to-ground wireless communication system for medium- and high-speed maglev trains. Background technique [0002] The maglev operation control system is connected with equipment or systems such as vehicles, traction, lines and turnouts in the maglev transportation system to complete tasks such as control of train operation, safety protection, automatic operation, management and scheduling. The maglev operation control system is composed of CCS (Center Control System, central operation control system), DCS (Distributed Control System, partition operation control system), VCS (Vehicle Control System, vehicle operation control system) and communication subsystem. The safety-related functions in the operation control system are mainly realized through the partition operation control system and the vehicle operation control system, and the data transmission between the two i...
