Abstract: This paper studies the application architecture of cloud platform and the types and division of the services provided by the platform, and puts forward feasible plans for establishing rail transit cloud platform. Combined with cloud construction of the cloud platform of line/network control center, the paper proposes that centralized management and unified coordination need to be performed at the network level to manage services of each line, each professional system and each construction and resource operation project, and that analysis and application of the services need to be coordinated at the network level. This solution replaces the traditional interface relationship between each system, providing better support for networking. At the same time, the cloud architecture of the line/network traffic control system is analyzed based on the application of the cloud platform, and it is proposed to use a virtualization platform to support service systems. The application server and history server are both deployed on the cloud platform, and the dispatching workstation adopts the cloud desktop architecture, which provides a good example of service application at the line/network level.
