城市轨道交通无线宽带通信系统融合方案分析

目前城市轨道交通无线通信传输系统主要采用独立建设的模式,不利于实现资源共享和降低建设成本。在分析城市轨道交通无线通信建设现状和宽带无线通信技术的基础上,研究乘客信息系统、信号系统、无线调度系统等车地无线通信的业务功能需求。通过对无线宽带集群技术的分析,结合城市轨道交通行业的应用实例,探讨基于分时长期演进(TD-LTE)平台实现"多网合一"无线传输的可行性,提出基于TD-LTE技术的无线通信系统融合解决方案,该方案主要包含控制中心、车站/车辆段、车载等3个子系统。

Analysis on Integration Program in Urban Rail Transit Wireless Communication System

At present, the various urban rail transit wireless communication systems were mainly constructed independently, it is not conducive to the sharing of resources and reduce the cost of construction. Analysis on construction present situation of urban rail transit wireless communication systems and wireless communication technology, the demands of train ground communication function of passenger information system, signal system and wireless dispatch system were studied. Combined with wireless broadband technology and the examples of train ground communication system in urban rail transit , then, the feasibility of Multi-network integration wireless transmission platform based on TD-LTE is analyzed, and the integration scheme were proposed. There are three subsystems in this scheme, they are the control center, the station / depot and vehicle subsystems.
