城市轨道交通工程中的专用通信传输系统设计研究

Design and Research of Special Communication Transmission System in Urban Rail Transit Engineering

本文结合某城市轻轨2号线工程,对专用通信系统中的传输系统进行分析,对比了MSTP、OTN、PTN、增强型MSTP四种传输技术,在此基础上对通信传输系统方案的带宽、结构、环路保护方式和系统同步方案进行详细设计,相关设计结论满足具体工程项目实际需求。

This paper analyzed the transmission system of the special communication system and compared MSTP, OTN, PTN and MSTP+ transmission technologies in 2 project of city light rail line. This paper put forward the details scheme about bandwidth, structure, loop protection mode and system synchronization based on the comparison results. The relevant design conclusions meet the actual needs of specific engineering projects.
