400 MHz数字列调系统固定电台空口转接控制单元的设计与实现
Design and Implementation of Air Interface Transfer Control Unit for Fixed Station of 400 MHz DRTD System
摘要
Abstract
Currently,the 450 MHz analog radio communication system for train dispatching used in the normal-speed railways and branch lines has many problems,such as poor voice quality,low reliability,and forthcoming unavailability of the current frequency band,resulting in an urgent need for renewal and upgrade.In order to solve these problems,the 400 MHz Digital Radio communication system for Train Dispatching(DRTD)based on digital format is introduced.As the key equipment at the wayside,the fixed station performs the function of transferring the call services and data services between the wired channel and the wireless channel in the DRTD system.This paper designs the software structure divided by functional modules and the multithreaded programming mode for the air interface transfer control unit of the fixed station,to achieve the signaling interaction and service establishment between the mobile terminal and the wayside equipment of the DRTD system.关键词
