The invention relates to the field of intelligent production and manufacturing management technology, particularly to an intelligent factory system based on the internet of things technology and industrial big data. The intelligent factory system comprises a lower SCADA process control system, an intermediate MES manufacturing execution system, and an upper ERP business planning system. Therefore, problems of difficult real-time analysis and calculation, difficult accident tracing and restoration, high non-planned parking frequency, low work production efficiency, difficult non-transparent decision-making and difficult cooperation among the regional personnel are solved so as to improve the product output, reduce energy consumption and reduce the cost; the a humanized intelligent factory with equipment intelligence, modern management, and information computerization is established truly; and the core competitiveness of enterprise is enhanced.
