High-efficiency and high-precision adjustment method for ground antenna reflector of high-speed maglev train

Abstract

The invention discloses a high-efficiency and high-precision adjustment method for the ground antenna reflector of a high-speed maglev train. Time slot signal; S4, adjust the azimuth and pitch of the ground receiving antenna reflector, and record the ground base station receiving level; S5, adjust the reflector of S4 to the azimuth and pitch corresponding to the maximum receiving level; S6, adjust the ground The azimuth and pitch direction of the transmitting antenna reflector; S7, adjust the reflector of S6 to the azimuth and pitch corresponding to the maximum train receiving level; S8, the ground base station transmits the test completion signal to the vehicle base station; k=k+1, Return to S3; S9, analyze the receiving level table, adjust the reflector to the optimal azimuth and optimal pitch; S10, n=n+1, return to S2. The invention reduces the manual workload, greatly improves the adjustment efficiency and adjustment accuracy of the antenna reflector, and ensures that the adjustment of the antenna reflector reaches the optimal state.

Description

technical field [0001] The invention belongs to the technical field of vehicle-ground wireless communication, and in particular relates to a high-efficiency and high-precision adjustment method for an antenna reflector of a high-speed maglev train. Background technique [0002] In the train-to-ground wireless communication system of high-speed maglev trains, millimeter waves are widely used in train-to-ground wireless communication because of their wide frequency band, good anti-interference performance, and strong confidentiality. However, millimeter waves require high beam pointing accuracy, and slight changes in beam pointing will shift the beam coverage and affect the quality of vehicle-to-ground communication. In the high-speed maglev train vehicle-to-ground wireless communication system, the antenna reflector of the base station can change the polarization mode of the wireless signal, and the beam coverage can be adjusted by adjusting the azimuth and elevation of the a...
