DRTD系统固定电台控制设备管控模块设计与实现

Design and Implementation of Management and Control Module of Fixed Station Control Equipment in DRTD System

铁路无线列调通信技术和列车通信设备应用需求的发展,现有铁路通信技术将升级为DRTD、GSM-R或5G-R等数字制式无线通信。主要介绍列车数字无线调度通信系统(DRTD)中固定电台控制设备管控模块的设计,实现与调度操作台、固定电台以及数字列调接口服务器进行数据交互,对若干车站的固定电台以及所属终端进行管理,并将数字列调接口服务器的调度命令、车次号无线校核信息或进路预告发送到对应固定电台,保障铁路列调系统通信的可靠性。

With the development of railway wireless train dispatching communication technology and the application requirements of train communication equipment,China is promoting digital intercom technology in an all-round way.Because the 450MHz analog wireless communication in the railway wireless train dispatching system cannot carry out voice and data communication at the same time,and cannot carry out individual call,group call and has poor anti-interference ability,it will be upgraded to digital standard wireless communication such as DRTD,GSM-R or 5G-R.This paper mainly introduces the design of the control module of the fixed station control equipment in the Digital Radio Communication System for Train Dispatching(DRTD).It realizes data interaction with the dispatching console,the fixed station and the digital train dispatching interface server,manages fixedstations and their terminals in some stations,and sends dispatching commands,the wireless check information of the train number or the route notices from digital train dispatching interface server to the corresponding fixed stations to ensure the reliability of the railway train dispatching system communication.
