Abstract

The invention discloses a traveling rail side wireless tracking transmission method, device and system to overcome at least one of the defects of the prior art that frequency spectrum using efficiency is low, propagation power loss is high, and network fault positioning capacity is not available. The method comprises the steps of determining an antenna unit for communication corresponding to the current position and / or tending position of an N vehicle-mounted radio frequency unit in a first radio frequency receiving / transmitting array, and a radio frequency receiving / transmitting unit RF_N or RF node corresponding to the antenna unit for communication; sending radio frequency signals by means of the antenna unit for communication and the radio frequency receiving / transmitting unit RF_N to the N vehicle-mounted radio frequency unit on a first track in an adjacent region time-frequency overlapping mode, and / or receiving radio frequency signals from the N vehicle-mounted radio frequency unit on the first track. The device and system are high in frequency spectrum efficiency and low in power consumption, can be used for passenger communication as well as train running control, and can remarkably improve the traveling safety and traffic density of high-speed trains / subways.

Description

technical field [0001] The invention relates to the field of traffic, in particular to a method, device and system for wireless tracking and transmission on the side of a running track. Background technique [0002] Currently, high-speed railways and subways / city rails use existing cellular mobile communication networks to provide communication services to passengers. High-speed railways are characterized by fast movement speed and high user density. The resulting problems are: high-speed movement reduces the transmission efficiency from vehicle-mounted terminals to ground base stations or leads to dropped calls; high user density makes it difficult for cellular mobile communication capacity to meet passenger needs Actual demand. For the subway / urban rail, since the moving speed is lower than that of the high-speed rail, the reduction in the transmission efficiency from the vehicle-mounted terminal to the ground base station is smaller than that of the high-speed rail. Howe...
