Abstract:The modernization of the industrial chain of intelligent manufacturing reflects the improvement of the industrial base capacity, the optimization of the operation mode and the enhancement of the control power of the industrial chain. The operation of intelligent manufacturing industry chain modernization is based on the perception layer, network layer, implementation layer, application layer, and on this basis extends to key products, technology chain, operators, it generally goes through four stages of manufacturing automation, manufacturing information, manufacturing interconnection, and manufacturing intelligence. And each stage corresponds to the continuous maturity of a core link in the intelligent manufacturing industry chain system. In view of the difficulties faced by the modernization of China"s intelligent manufacturing industry chain, it should be promoted from making up the key short board links, promoting the development of enterprises, promoting the upstream and downstream coordinated development, developing industrial data, improving the development mechanism of the supply chain, and constantly improving the basic capabilities, control capabilities, linkage capabilities, factor allocation capabilities and risk prevention capabilities of the modernization of the intelligent manufacturing industry chain.
