摘要
5G移动通信网络采用新一代蜂窝移动技术,其数据传输速率远高于4G网络.将5G技术应用于城市轨道交通PIS系统中,可改善目前基于无线局域网构建PIS通信信号易受干扰和故障频发等弊端.本文以LTE-A技术、MIMO增强技术和MEC技术等5G移动通信关键技术为切入点,从城市轨道交通系统的核心层、接入层和应用层出发,构建了全新的智慧轨道交通系统,助推轨道交通行业数字化转型.
Abstract
5G mobile communication networks adopt the new generation of cellular mobile technology,and their data transmission rates are much higher than those of 4G networks.Applying 5G technology to urban rail transit PIS systems can improve the current drawbacks of constructing PIS communication signals based on wireless local area networks,such as susceptibility to interference and frequent faults.This article takes key 5G mobile communication technologies such as LTE-A technology,MIMO enhancement technology,and MEC technology as the entry point.Starting from the core layer,access layer,and application layer of urban rail transit systems,a new smart rail transit system is constructed to promote the digital transformation of the rail transit industry.
