摘要
调度通信是GSM-R机车综合无线通信设备(以下简称CIR)的一个主要功能,实际使用时需要经常对CIR的GPS数据库进行维护。首先介绍了CIR的主要功能和工作原理,接着介绍了GPS单元和GPS数据库在CIR实现调度通信功能中的作用,介绍了CIR的数据传输通道和工作模式,最后提出一种利用CIR的数据传输通道,在GPRS接口服务器配合下进行GPS数据库动态升级的方法。
The dispatching communication is one major function of GSM-R Cab Integrated Radio communication equipment, for short, CIR. The maintenance of GPS database of CIR needs to be done in actual application. The main functions and working principle of CIR are introduced, the role of the GPS unit and GPS database in CIR dispatching communication are described, and the CIR data transmission channel and working mode are introduced. Finally, it is proposed that GPS database could be upgraded dynamically using CIR transmission channel in cooperation with GPRS interface server.
