城市轨道交通云建设探讨

大规模的城市轨道交通(以下简称"城轨交通")建设、运营及管理需要信息化手段支撑,但传统的企业信息化建设模式周期长、投资大、涉及系统多、集成和实施难度高。云计算技术的出现以及逐渐成熟的应用模式,使得建设符合城轨交通行业管理需要的云服务成为可能;同时可解决由于城轨交通企业各自建设信息系统导致的资源分散、难以共享,形成信息孤岛和资源浪费等问题;可快速提升行业信息化普及水平,降低整体建设成本。通过分析城轨交通信息化的现状,探讨城轨交通云建设的必要性,提出在行业内采取合作与合资2种建设模式,搭建Iaa S(基础设施即服务)、Paa S(平台即服务)、Saa S(软件即服务)3个层次的城轨交通云服务,以及分阶段实现的云建设思路,为城轨行业在云计算时代加速信息化发展提供借鉴和参考。

Research on Cloud Construction of Urban Rail Transit

in recent years, the domestic urban rail transit (hereinafter referred to as the "urban rail transit") into the rapid development period. Mass urban rail transit construction, operation and management needs information technology support, but the traditional enterprise information construction mode of long, large investment, involving system, integration and implementation is difficult. The emergence of cloud computing technology and gradually mature application mode, making the construction of urban rail transportation industry management needs of cloud services become possible, and can solve the urban rail transportation enterprise information system, resource scattered, difficult to share, forming information island and resource waste and other issues, rapid promotion of industry information technology to reduce the overall construction cost. This paper analyzes the current situation of urban rail transit information, and discusses the necessity of building urban rail transit and the construction of the ideas and modes.
