Implementation of Cloud-based Urban Rail Big Data Platform

Abstract

Facing the wave of digital transformation of urban rail, it has proposed a cloud-based big data platform construction plan following the innovative urban rail development in the paper. The cloud platform provides virtualized resources and services such as computing, storage, networking, security, and Platform-as-a-Service components for the big data platform. The big data platform works as the Data-as-a-Service layer of the cloud, which integrates multiple business application data, conducts data governance, forms data assets, and provides secure, universal, and flexible data sharing services to various advanced intelligent applications. The low-code historical data interface and real-time data service is an innovative function to meet new demands for intelligent operation. Data modeling and optimization in the face of the characteristics of the Hadoop platform are also mentioned. The solution provides data support for the application of intelligent urban rail and realizes the integration of cloud and big data platforms. Meanwhile, the data is passed from producers to consumers through data reorganization of big data platforms, which could isolate the influence of data errors and model changes.
