The Application of Rail Transit Communication and Transmission System in Rail Transit
轨道交通通信传输系统在轨道交通中的运用

摘要

在中国城市轨道交通的网络体系中，传输网络是占据一个主导地位的主要网络。它不但为公务、无线、视频控制、专用、电话以及与乘客控制和通讯有关的其他子系统来提供数据、图象和声音的传播通道，同时还为车辆的自动控制、电气控制、自助售检票以及系统的环境控制等子系统来提供传播信道。该文还重点分析了轨道交通传输技术目前的应用状况以及四种新技术，并为未来的通讯传送制式以及选择建设新线提供了意见。

Abstract

In the network system of urban rail transit in China, the transmission network is a dominant network. It not only provides data, image and sound transmission channels for official, wireless, video control, dedicated, telephone, and other subsystems related to passenger control and communication, but also provides transmission channels for the automatic vehicle control, electrical control, self-service ticket sales, and environmental control subsystems of the system. The paper also focuses on the current application status of rail transit transmission technology and the four new technologies, and provides suggestions for the future communication transmission system and the selection and construction of new lines.
