Problems solved by technology

[0002] When the train is running at high speed on a flat and open area, the beamforming of the nearby communication base station can be used to achieve communication coverage. However, due to the geographical location, the base station cannot provide communication support when driving through the pipeline, resulting in the end-users of the train appearing in the pipeline. Easy to lose signal or weak signal

Abstract

The invention provides a communication method for a train passing through a pipeline and related equipment. The method is based on laser communication, and when a train is outside a pipeline, a terminal user communicates with a base station outside the pipeline; when the train drives into the pipeline, if the power intensity of the first communication signal of the base station outside the pipeline is smaller than a preset first threshold value, switching the communication object to an optical base station with the strongest power intensity of the communication signal in the pipeline; when the power intensity of a second communication signal between the terminal user and the optical base station is smaller than a preset second threshold value due to the fact that the train travels away from the optical base station, the base station is switched to the optical base station with the higher power intensity of the communication signal, and therefore the optical base stations can be continuously switched in the traveling process in a train pipeline; communication support can be provided for the terminal user of the train all the time.

Description

technical field [0001] The present application relates to the field of wireless communication technologies, and in particular, to a communication method and related equipment for a train passing through a pipeline. Background technique [0002] When the train travels at high speed on a flat and open area, it can achieve communication coverage by beamforming through the nearby communication base station, but when it travels through the pipeline, due to the geographical location, the base station cannot provide communication support, resulting in the end user of the train. It is easy to lose the signal or the signal is weak. [0003] Based on this, a communication method is needed to meet the communication requirements of end users when the train is traveling in the pipeline. SUMMARY OF THE INVENTION [0004] In view of this, the purpose of this application is to provide a communication method and related equipment for a train passing through a pipeline. [0005] Based on ...
