New Generation Urban Rail Transit Automation Systems Fusion Platform Based on Cloud-edge Cooperation

Cloud computing has been extensively used in the integration and fusion of urban rail transit automation systems. The existing centralized cloud platform construction is associated with some issues, such as high network load, long userperceived latency, and large data-center scale. This paper optimizes and constructs the four-layer architecture of a new generation fusion platform with an edge, foundation, platform, and application layers. Through the cooperation of edge-cloud computing, real-time performance is improved and the scale of IDC (internet data centers) is controlled. The process is conducive to the development of intelligent applications. This paper introduces typical application examples in a step-by-step manner.
