The invention discloses an industrial Internet system based on cloud-side cooperation. The system comprises industrial terminal equipment, an edge gateway and industrial edge cloud, which are sequentially connected through an intranet or private network environment, and the industrial edge cloud is in resource connection with an extranet. The industrial edge cloud is used for carrying out storage,processing and modeling analysis on data processed by the edge gateway, production lines, pipelines, PLCs, robots, numerical control machine tools and other equipment on an industrial site can be connected to form an organic whole so as to meet the requirements of low time delay, high reliability and diversification of on-site application, and intelligent data processing is carried out in cooperation with the industrial edge cloud. The edge gateway carries out unified acquisition on production data of enterprises, supports data preprocessing on an edge side, and pushes the data to the industrial edge cloud for storage, processing and further modeling analysis, and cloud-side cooperation of resources, data, intelligence and services is realized through an edge cloud network topology relationship.
