基于5G的城市轨道交通列车接入单元实现方案

Implementation Scheme of Urban Rail Transit Train Access Unit Based on 5G

近年来,有轨电车行业凭借各种优势得到了迅速发展,但是考虑到专网建设的成本较高,有轨电车业务传输方案一般基于普通运营商网络。针对5G通信技术在交通垂直行业的产业化应用,以及无线通信系统低延时、高可靠的需求,迫切需要研制5G列车接入单元(Train Access Unit,TAU)设备,来满足轨道交通通信业务在5G运营商网络下的传输要求。设计了一款5GTAU,详细介绍了软硬件实现方案,实现了5G运营商网络下有轨电车业务的传输,阐述并论证了该设备在轨道交通通信领域的可行性。

In recent years,the tram industry has developed rapidly with various advantages.However,considering the high cost of private network construction,tram data transmission solutions are generally based on the ordinary operator network.Aiming at the industrial application of 5G communication technology in the vertical transportation industry,as well as the demand for low latency and high reliability of wireless communication system,it is an urgent to develop 5G Train Access Unit(TAU)equipment to meet the transmission requirements of rail transit communication service under the 5G operator network.A 5G TAU is designed and the software and hardware implementation scheme is introduced in detail,achieving the transmission of tram service under the 5G operator network.The feasibility of the equipment in the field of rail transit communication is elaborated and demonstrated.
