Abstract: In this paper，with the development trend of large-scale，automatic and low energy consumption of CDQ process，an intelligent system based on industrial Internet for CDQ production is proposed. Through collection，storage and analysis of industrial data，the processed data is synchronized to the industrial Internet platform，and the linkage control model between the upper and lower levels in the system is used to achieve CDQ intelligent production in manner of efficiency， accuracy，stability and safety.
