Abstract: Aiming at that the existing research lack of the overall development of smart factories, and in order to grasp the latest development of future factory model, the concept, connotation, frame structure and key technologies of smart factory were reviewed. The definition of smart factory was summarized based on the research status of smart factory and current instance construction. Combining the meaning of smart factory and based on the digital factory, the main characteristics of smart factory was summarized. From the point of technology, three key technologies of smart factory, the big data technology in data acquisition technology, transmission technology and analysis technology, virtual simulation in MBD technology, the simulation system architecture and simulation model of technology and artificial intelligence in machine learning, natural language processing and image processing were discoussed. The results indicate that big data technology, virtual simulation technology and artificial intelligence are the key technologies of smart factory. At the same time, there is still a long way in that the key technologies are used on a large scale in the construction of the factory and the real factory intelligence is achieved.

Key words: smart factory; big data technology; virtual simulation technology; artificial intelligence
