The invention discloses a rail transit vehicle-ground communication link switching test method, which comprises the following steps: step 1, oppositely arranging a vehicle-mounted simulation unit and a ground simulation unit on two sides in a test darkroom, wherein the vehicle-mounted simulation unit comprises a vehicle-mounted communication module, and the ground simulation unit comprises a plurality of base station communication modules arranged at intervals; step 2, debugging base station communication modules of the ground simulation unit, wherein communication ranges of adjacent base station communication modules have an overlapping area; step 3, controlling the vehicle-mounted simulation unit to rotate within the horizontal 180-degree range of the direction face facing the ground simulation unit, meanwhile, the vehicle-mounted communication module being in wireless communication with the ground simulation unit, and the working states of all base station communication modules in the ground simulation unit being switched according to a set link switching method; and step 4, processing and analyzing the communication data of the vehicle-mounted communication module and the communication data of the base station communication module. According to the invention, the vehicle-ground communication dynamic switching test can be conveniently carried out, the cost is low, and the simulation degree is high.
Description
technical field [0001] The invention relates to the communication field of rail transit vehicles, in particular to a communication link switching test method and system for rail transit vehicles. Background technique [0002] With the continuous growth of high-speed train control and high-reliability data service transmission and the continuous growth of passenger demand for high-speed communication services during the ride, how to provide high-speed, high-reliability communication services in the high-mobility environment of high-speed railways is of great significance . In order to achieve high-speed transmission of train-ground data, the existing train vehicle communication terminals and trackside base stations usually use directional narrow-wave communication equipment, which has a long communication distance and a narrow communication angle range, but the communication intensity is high within the communication angle range. [0003] The high-speed operation of the trai...
