哈大客专引入哈尔滨枢纽通信传输系统研究

Research on communication transmission system of leading harbin-dalian passenger dedicated line into harbin terminal

根据哈大客专引入哈尔滨铁路枢纽运输组织要求,相关规划铁路线路接入需求,结合通信传输技术的发展,进行详细业务需求分析,通过综合技术方案比选,确定采用MSTP技术构建通信传输系统。结合枢纽现状及安全策略,确定传输设备节点设置。根据节点位置及拓扑结构,进行详细光中继段距离及通道利用率计算。通过构建哈大客专,引入哈尔滨铁路枢纽通信传输网,有效地保证铁路通信畅通。设备投入运营以来,运行稳定可靠,为后续的项目提供很高的借鉴。

Based on the requirement of leading Harbin-Dalian Passenger Dedicated Line into Harbin terminal traffic transport organization,and the requirement of relate planned railway lines,combined with the development of the communication transmission technology,the detailed business needs are analyzed.Comparing integrated technology programs,MSTP technology is adopred to establish the transmission network.In combination with the terminal status and the security policy,the node setting of the transmission network are finalized.Combined with node location and topology,the optical relay segment distance and the channel utilization are detailedly calculated.Through the communication transmission network of leading Harbin-Dalian Passenger Dedicated Line into Harbin terminal,it assures the railway smooth communication.The equipment runs stably and reliably after operation.Moreover,it may be a design reference for the follow-up project.
