摘　　要：目前国内轨道交通行业正处于蓬勃发展时期,但运维新模式的技术应用、设备配置与规模增长不相匹配,运维的压力日益增大,这对正线故障事件的应对处理能力和运营网络自救能力提出了更高的要求。结合城市轨道交通车辆智能化发展需求,亟需开展车载无线传输系统的研究与设计。首先分析了城市轨道交通车载无线传输系统的典型工作场景、功能要求,其次针对无线传输系统的车载数据流向、车地数据传输方式以及车地传输安全防护的现状和问题进行了重点分析,最后提出上述典型问题在实现层面的设计思路。At present,the domestic rail transit industry is developing vigorously,but the technical application and equipment configuration of the new operation and reform mode do not match the scale growth,and the pressure of operation and maintenance is increasing day by day,which puts forward higher requirements for the ability to deal with the main line fault events and the self rescue ability of the operation network.Combined with the intelligent development needs of urban rail transit vehicles,it is urgent to carry out the research and design of on-board wireless transmission system.Firstly,this paper analyzes the typical working scenarios and functional requirements of the on-board wireless transmission system of urban rail transit.Secondly,it focuses on the current situation and problems of the on-board data flow direction,vehicle-ground data transmission mode and vehicle-ground transmission safety protection of the wireless transmission system.Finally,it puts forward the design ideas in view of the above typical problems at the implementation level.
