[Abstract]
Cloud computing have been widely used in the integration and fusion of urban rail transit automation system. The existing centralized cloud platform construction has some issues, such as high network load, longer user-perceived latency, and large scale of data center. This paper optimizes and builds a four-layer overall architecture of a new generation fusion platform with edge layer, foundation layer, platform layer and application layer. Through the cooperation of edge-cloud computing, the real-time performance is improved, the scale of DC is controlled, and conducive to the development of intelligent applications. This paper put forward a step-by-step manner and typical application examples.
