摘　　要：结合丽江有轨电车1号线,对LTE专网通信与5G公网通信冗余融合的通信方案进行详细研究分析。丽江1号线使用LTE专网作为信号系统车-地无线通信数据传输的主用通道,5G公网作为备用通道,负责信号系统中列车与地面信号设备之间数据报文的发送和接收,实现信号系统地面控制中心、车站、车辆基地、轨旁和车载信号设备之间的数据信息传输,保证信号系统通信业务数据正常。详细论述LTE专网与5G公网融合通信方案,对城市轨道交通行业数据通信技术未来的发展提供了重要的参考。This paper conducts detailed research and analysis on the communication scheme based on the redundant fusion of LTE private network and 5G public network communication,considering the circumstances of Lijiang Rail Transit Line 1.For Lijiang Line 1,the LTE private network functions as the main channel for train-wayside transmission of wireless communication data for the signaling system,while the 5G public network serves as the standby channel for sending and receiving data messages between the onboard and wayside signaling equipment in the signaling system,enabling data transmission among wayside control centers,stations and vehicle bases,and between wayside and onboard signaling equipment.The proposed scheme ensures the normal operation of data communication services in the signaling system.This paper elaborately discusses the integration communication solution of LTE private network and 5G public network,providing an important reference for the future development of data communication technology in the urban rail transit industry.
