Urban Rail Cloud Architecture Based on Cloud Platform

The problems and challenges in line operation transformation are described herein from the perspective of the current development trend of urban rail transit informatization. ?According to the Smart city rail transit information technology architecture and network security specifications, the design and development of the industry informatization involves several vital aspects: evaluation of urban rail cloud architecture as a basic platform in promoting the development of urban rail transit informatization; research on the functions and requirements of the cloud platform, network security, data sharing, and intelligent operation and maintenance O&M modules; and emphasis on the cloud platform as the key technology of the urban rail cloud architecture, its functional requirements, and technology choices. In real-world projects, the security, reliability, stability, and scalability of the cloud platform should be prioritized, and the building of an open information platform is suggested for all services of the urban rail network and the multiple modes of the urban rail.
