城轨车辆大数据平台设计与应用

Design and Application of Big Data Platform for Urban Rail Vehicles

列车网络设备实时数据具有高频次、变量多、小批量、解析复杂的特点,需要能够实时接入、实时解析以及动态扩展的软件系统架构。本文针对城轨车辆实时数据特点和处理需要,设计了城轨车辆大数据平台。该大数据平台设计时考虑了安全性、实时性和高效性,并从数据接入、计算、存储、交换、管理等各方面进行了设计,能够解决海量异构数据的标准不统一、接入解析难、存储难等问题,可以实现秒级数据处理以支撑快速响应的应用需要,并已经在实际项目中进行了应用。该平台运行稳定,在架构上可横向扩展,完全满足客户需求。

The real time data of train network equipment featuring high frequency,many variables,small batches and complex analysis requires the software system architecture that can connect,analyze in real time and dynamically extend.This paper designs the big data platform of urban rail vehicles according to the feature and processing requirement of real time big data.The design of the big data platform is designed from data connection,computing,storing,exchanging and management in terms of safety,real timing and high efficiency and can solve the difficult issues of non-uniform standard of massive amounts of heterogeneous data,difficulties in access analysis and storage,etc.,can realize the second-level data processing to support the application needs of rapid response,and has been applied in actual projects.This platform has been in stable operation and can be extended in architecture,completely satisfying the demand of the users.
