Resource management method based on train position and cargo handling capacity maximization

Abstract

The invention provides a resource management method based on a train position and cargo handling capacity maximization. When vehicle-vehicle communication reuses uplink or downlink path frequency spectrum resources of vehicle-ground communication trains, the existing interference situation is analyzed; the suitable vehicle-ground communication trains are selected, and the vehicle-vehicle communication is made to reuse the uplink or downlink path frequency spectrum resources of the vehicle-ground communication trains; whether the vehicle-ground communication trains in the selectable range meet the reuse conditions or not is judged in sequence according to a signal-to-interference and noise ratio threshold value of a vehicle-ground communication uplink or downlink path receiving signal and a signal-to-interference and noise ratio threshold value of a vehicle-vehicle communication link path receiving signal, and a train whose vehicle-ground communication frequency spectrum resources are reused is determined; on the basis that the vehicle-vehicle communication reuses vehicle-ground communication uplink or downlink path frequency spectrum resources, the total cargo handling capacity of a system is controlled to be maximized through power. The method reduces or eliminates the interference between the vehicle-vehicle communication and vehicle-ground communication and maximizes the number or success rate built by communication connection, and therefore the total cargo handling capacity of the system is maximum.

Description

technical field [0001] The invention relates to a wireless spectrum resource management method based on maximizing train position and throughput, and belongs to the technical field of spectrum resource management for urban rail transit train control information transmission. Background technique [0002] There are two ways to allocate spectrum resources for vehicle-to-vehicle communication. One is to allocate part of the spectrum resources for vehicle-to-ground communication dedicated to vehicle-to-vehicle communication, and the other is to allow vehicle-to-vehicle communication to multiplex vehicle-to- - Spectrum resources of ground communication trains to realize direct communication. In urban rail transit, in order to improve the spectrum efficiency and allow more resources to be used to transmit train control integrated services, such as CCTV, PIS, etc., it is hoped that the realization of vehicle-to-vehicle communication will improve the performance of the train control...
