A wireless communication system and method for a train

Abstract

The invention discloses a wireless communication system and a wireless communication method of a train. The system comprises a motion monitoring module, a dynamic reconnection module, a data management module and a track radio frequency module, wherein the motion monitoring module is used for monitoring and calculating a real-time position of the train; the dynamic reconnection module is used for dynamically linking with a ground wireless communication device, and judging and controlling node communication of the train with a certain node of the ground wireless communication device according to the real-time position fed back by the motion monitoring module as well as preset conditions and an algorithm model; the data management module is respectively coupled to the dynamic reconnection module and the motion monitoring module, and is used for taking charge of the management and coordination work for the dynamic reconnection module, the motion monitoring module and the track radio frequency module and sending a data communication command to the track radio frequency module according to the returned data; and the track radio frequency module is coupled to the data management module, and finishes data communication between the ground wireless communication device and the train according to the data communication command. The system and the method disclosed by the invention are beneficial to improving the wireless communication quality of the train.

Description

technical field [0001] The present invention relates to a communication technology, in particular to a wireless communication system and method. Background technique [0002] In the current high-speed rail vehicle-ground communication system, due to the high-speed train speed, the train-ground communication switching is too frequent, and the vehicle-ground switching delay is relatively large, which seriously affects the vehicle-ground communication effect and cannot meet the quality requirements of the future rail transit mobile Internet network. Also can't satisfy passenger's current mobile Internet application demand. [0003] It should be noted that the above introduction to the technical background is only for the convenience of a clear and complete description of the technical solution of the present application, and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are known to those skilled in...
