上海轨道交通专用无线宽带集群系统应用研究

Application Research on Dedicated Wireless Broadband Trunking System of Shanghai Rail Transit

上海轨道交通从14、15、18号线开始,逐步引入基于LTE的宽带集群系统,以满足形式多样化、信息多源化的运营调度需求。网络侧系统设计、终端侧功能设计和分配是宽带集群系统部署过程中的关键环节。针对上海轨道交通运营调度机制、岗位设置和职责等,设计了系统架构、与TETRA互联互通方案、外部接口、定制终端标准功能和终端分配原则等工程应用关键内容,以促进宽带集群系统在轨交行业的全面推广和应用。

Beginning with line 14,15 and 18,broadband trunking communication system based on LTE has been gradually deployed to meet the increasing requirements of operation and dispatching for more diversified forms and multi-source information in Shanghai rail transit.Whereas the system design of network side,function design and allocation of terminal side are the key links in the deployment process of broadband trunking communication system.Therefore,in the light of the operation and dispatching mechanism,post setting and responsibilities of Shanghai rail transit etc.,the key contents of engineering application,system architecture,interconnection scheme with TETRA,external interfaces,standard functions of customized terminal andprinciples of terminal allocation were designed and put forward with a motivation to advance the comprehensive promotion and application of broadband trunking communication system in the rail transit industry.
