Abstract: Based on a comprehensive literature review of the smart factory,its nature composed of internet of things,intelligent manufacturing execution system and manufacturing collaboration was discussed,and its big data characteristics were also analyzed.The technical framework contained the physical interconnection layer,the object sensing layer,the data analysis layer,the business application layer and the cloud service layer was proposed.The content of critical big-data-based manufacturing optimization technology for three middle layers was elaborated,which involved the big data integration method,the big data storage method,the correlation analysis method and the correlation description method.The big-data-based technical system would provide important referential value for manufacturing industry to realize the smart factory.

Key words: smart factory, big data, technical framework
