基于5G城市轨道交通站内外一体化导航系统设计及研究

Research on integrated navigation design of urban rail transit station based on 5G

在城市轨道交通智慧化、网络化发展的同时,提高乘客服务水平也至关重要。为解决城市轨道交通中乘客面对站内换乘复杂、服务设施难找、车站出口多而指引信息少的问题,文章基于5G移动通信大带宽、低时延、高精度的特点,提出一种基于5G定位的城市轨道交通站内外一体化导航技术应用架构,通过站内外地图数据采集、加工及制作业务流程,建立三维地图数据,运用端到端语音导航技术、站内地图发布技术、结合实景路口放大图技术,设计一套精细化、移动化、自主化、智能化的站内外一体化导航系统。从而形成基于“移动互联网+乘客”,满足乘客个性化、移动化和多样化出行场景需求的便捷引导服务体系,为乘客提供多角度全方位的出行方式。

With the intelligent and networked development of urban rail transit stations,it is very important to improve passenger service.In order to solve the problems of complex transfers inside the transfer stations,difficult-to-find service facilities,many exits with few guidance information in urban rail transit systems,based on the low latency and high precision characteristics of large bandwidth 5G mobile communication,this paper proposes an application architecture of integrated navigation technology in and out of urban rail transit station based on 5G positioning.Through the business process of data acquisition,processing and production of internal and external station maps,3D map data was established,and a refined,mobile,independent and intelligent integrated navigation system of the station and internal and external map is designed by using end-to-end voice navigation technology,station inland map publishing technology and real road enlargement technology.Thus,a convenient guidance service system based on"mobile internet+passengers"can be formed to meet passengers’needs for personalized,mobile and diversified travel scenarios,and provide them with multi-angle and all-round travel modes.
