摘要：
Digital twin could faithful map the physical world. The digital twin of production process in the workshop can make the production process more transparent, and the production can be optimized with the twin data. With the theoretical background of digital twin, the framework of the digital twin system for production process in the workshop was constructed. The key technologies which included the method of digital twin modeling for key factors in the workshop, physical entity data collection based on OLE for Process Control Unified Artichitecture(OPC-UA) and real-time mapping of workshop operation were elaborated. Meanwhile, the digital twin system for a production line was realized, which verified the correctness and effectiveness of the proposed method. The proposed method provideed the technical solution to the realization of digital twin for production process in the workshop. © 2019, Editorial Department of CIMS. All right reserved.
