摘要
针对国产陆地集群无线电(TETRA)数字集群系统在北京轨道交通中的应用,围绕TETRA数字集群系统已有功能,提出了3种适合于城市轨道交通使用需求的特殊功能:专用无线通信系统的全网录音功能、惯导组合GPS接收模块利用TETRA短数据业务实现车辆定位的功能和乘客紧急对讲功能。通过对这3种功能的深入分析,描述了实现这3种功能所需要解决的核心问题,并给出相应的解决方案。通过在示范线路的实际应用测试,验证了功能的可靠性和适用性。
In view of the application of domestic TETRA digital trunked system in Beijing rail transit,this paper puts forward three special functions suitable for urban rail transit based on existing functions of TETRA digital trunked system, such as whole recording function of private wireless communication system,vehicle positioning function implemented by INS and GPS receiving model based on TETRA short data service and emergency intercom function of passengers.Based on the in-depth analysis on these three functions,this paper describes the core problems to be resolved for these three functions, and presents the appropriate solution.The actual application test on the model lines verifies the reliability and applicability of these three functions.
