Abstract: The present application discloses an edge cloud system, a server, and a cloud control platform. The edge cloud system includes: an edge cloud access gateway module configured to access data of the road side terminal, the vehicle terminal, the third party platform and the regional cloud; a standardized hierarchical sharing interface module connected to the edge cloud access gateway module, wherein the standardized hierarchical sharing interface module is configured to standardize and classify the data of the road side terminal, the vehicle terminal, the third party platform and the regional cloud accessed by the edge cloud access gateway module to form multiple levels of standardized data; wherein standardized data at each level of the multiple levels of standardized data is available to be called only by a module with corresponding level of that of the standardized data.
