基于Hadoop平台的地铁NCC数据中心方案研究

Research of Hadoop Platform for Metro Data Center Construction

摘要:

线网指挥中心是地铁管理控制中的承上启下的重要环节,接入线网各线路的控制中心,实时的监测线网整体的运营状况；并通过与上级政府交通管理部门系统的对接,将相关数据提交至交通管理系统,配合交通管理部门的工作；数据中心是线网指挥中心的核心环节,存储线网所有线路的生产数据和业务数据；目前线网指挥中心的数据中心都是基于传统的数据仓库的架构来创建的,而随着线路的不断增多,数据的种类和数量都在不断增加,传统数仓暴露出成本高,扩容难,维护困难的缺点；该方案提出的基于Hadoop大数据平台的数据中心建设方案,极大地降低了使用和维护成本,Hadoop生态圈包含了各类的组件模块,能够解决建设和使用中遇到的各类问题,提高了数据中心的性能。

Abstract:

The network control center, which access to the line operation control center, plays an important role in the metro management and control by the way of real time monitoring the overall operation status of the metro network. And also submit the relevant data to the traffic management system so as to coordinate with the work of the government traffic management department. The data center, which stores the overall network production data and business data, is the core of the network control center. At present, the data center of the network control center constructed based on the traditional data warehouse architecture. With the number of the line and data increasing, the traditional warehouse exposed high cost, difficult expansion and maintenance and other shortcomings. This paper proposes the data center construction scheme based on the Hadoop big data platform, which greatly reduces the use and maintenance costs. The Hadoop ecosystem contains various modules, can solve all kinds of problems encountered in the construction and use of the data center, as the result, improves the performance of data center.
