摘要
机车综合无线通信设备(CIR)用于实现机车和调度台之间的通信,兼容当前铁路调度系统中使用的450MHz和GSM-R二种通信方式。为实现以上二种通信方式的自动切换,以及450MHz通信区段内通信频点的选择,研究设计了一种基于GPS的卫星定位单元。介绍了卫星定位单元的总体设计、硬件结构和算法软件。现场实验结果表明,设计的卫星定位单元能够在使用中准确地实现通信方式和通信频点的自动切换,满足CIR的通信要求。
Cab integrated radio communication equipment,i.e.CIR,can realize the communication between the train and the dispatching station.CIR contains the two communication modes： 450MHz and GSM-R,which are used in current railway dispatching system.For automatic switching between the two modes and selection of communication frequencies used within the 450MHz zone,a kind of satellite positioning module based on GPS is designed.System design of the satellite positioning module,as well as hardware structure and algorithms software,is introduced.The application trials on train have showed that the satellite positioning module can meet the communication requirements of the CIR.
