摘　　要：针对城市轨道交通列车无线调度通信系统维护工作量大、故障诊断困难、各制式检测系统不兼容等问题,设计了一种基于LTE-M(Long Term Evolution for Metro)和陆地集群无线电(TETRA,Terrestrial Trunked Radio)多制式融合的专用无线通信检测系统。文章阐述了该系统的构成和架构,以及列车无线调度通信系统的路测数据分析、历史数据回溯、故障诊断定位等功能。采用多线程处理等技术,实现了对TETRA与LTE-M多制式列车无线调度通信系统信号场强的自动采集。试验结果表明,该系统运行稳定,为城市轨道交通列车无线调度通信系统正常运营提供了更好保障。This paper proposed a dedicated wireless communication detection system based on LTE-M(Long Term Evolution for Metro)and TETRA(Terrestrial Trunked Radio)multi-standard integration,which addressed the issues of heavy maintenance workload,difficult fault diagnosis,and incompatible detection systems for urban rail transit train wireless dispatching communication system.The paper elaborated on the composition and architecture of the system,as well as the functions of road test data analysis,historical data tracing,fault diagnosis and localization in train wireless dispatching communication systems,adopted techniques such as multi-threaded processing to implement automatic collection signal field strength information for TETRA and LTE-M multi-standard train wireless dispatching communication systems.The experimental results show that the dedicated wireless communication detection system operates stably and provides better guarantee for the normal operation of the urban rail transit train wireless dispatching communication system.
