上海城市轨道交通线路传输系统大修改造规划研究

Research on Remodeling Plan of Line Transmission System for Shanghai Urban Rail Transit

上海城市轨道交通线路传输系统目前面临着业务增长、架构变化等问题。通过研究传输系统的制式选型、组网架构,对其业务需求和节点部署进行总结,得出采用混合制式设备搭建多中心共环组网架构的模式更适合上海城市轨道交通既有线路传输系统大修改造的环境和要求的结论。在此基础上,制订了上海城市轨道交通线路传输系统的大修改造规划方案,在未来10年内将传输系统打造成满足业务过渡需求、统一容量规格、集中化智能管理的可靠系统。

Shanghai urban rail transit line transmission system is faced with issues such as business growth and structure change.Through the study of equipment selection and network architecture,the business requirements of line transmission system and node deployment are summarized,and it is concluded that the multi-center co-ring network architecture of hybrid system equipment is more suitable for the environment and requirement of Shanghai urban rail transit existing line transmission system remodeling.On this basis,the remodeling plan is formulated,aiming at building the transmission system into a reliable system that meets the business transition needs,unifies the capacity specifications and centralizes the intelligent management within ten years.
