In order to construct a smart factory operation system with the characteristics of " comprehensive sensing, interconnected device, digital integration and intelligent prediction", aiming at the lack of intelligent decision making in traditional factory/workshop control system, a smart factory architecture and information system integration model were proposed based on digital twins. The problem of virtual integration of factory control system with physical factory based on digital twins, such as high degree of automation ,system based on digital twins and physical factory were promoted. Furthermore, the application of micro-service architecture ,virtual simulation system, industrial internet of things and other technologies were highlighted in the system based on digital twins. To probe into the information integration between architecture and interface of the system based on digital twins, the solution of problems were carried out. Finally, to illustrate the advantages of visualization, real-time, maneuverability and collaboration in virtual production system based on digital twins, an application case of digital twins in the assembly workshop of personalized car models was presented.
