铁路“两网”融合车间班组数据通信接入工程研究

Research on Engineering Technology Solution of Workshop Team Data Communication Access in Railway "RDCN and ICN" Integration

铁路数据通信网和综合计算机网(简称“两网”)是铁路各项运输业务正常、安全运行的承载平台,“两网”融合改造是铁路信息化及铁路发展的重要内容与保障.其中车间、班组数据通信接入是铁路信息化网络接入的“最后一公里”.以广铁集团湖南地区京广线、广东地区、海南地区的车站、班组网络为例,分析调查了这些基层接入网络的既有状况和存在的问题,论述了车间、班组数据通信接入网改造的必要性,分析了改造的需求,提出了改造目标,重点进行了技术方案比选,提出了工程解决方案.可供其他类似工程参考和借鉴.

The railway data communication network and integrated computer network(RDCN and ICN)are the carrying platforms for the normal and safe operation of various railway transportation services.The integration of“RDCN and ICN”is an important technique to facilitate the progress of railway informatization.The data communication access of workshops and teams is called the“last mile”of railway information network access.Taking the stations and team networks of Beijing-Guangzhou Railway in Hunan section,and Guangdong and Hainan area of Guangzhou Railway Group as an example,the author analyzed and investigated the existing status and existing problems of these base-level access networks,discussed the necessity of network transformation in data communication access of workshops and teams.Moreover,the needs of the transformation were discussed,,the transformation objectives were proposed.Finally,the author focused on the comparison of technical solutions,and.proposed engineering solutions,which could be served as a reference for other similar projects.
