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应用于城市轨道交通系统(PIS)中,可改善目前基于无线局域网构建PIS通信信号易干扰和故障多等弊端。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智化转型。
5G mobile communication network adopts the new generation cellular mobile technology, and its data transmission rate is ten times higher than that of the fourth generation mobile communication network. The application of the fifth generation mobile communication network in the PIS wireless system of urban rail transit can improve the disadvantages of easy interference and many faults of communication signals in the PIS based on wireless LAN. Starting from the key technologies of 5G mobile communication such as LTE-A technology, MIMO enhancement technology and MEC technology, this paper constructs a new intelligent rail transit system from the core layer, access layer and application layer of urban rail transit system, boost the digital intelligence transformation of rail transit industry.
