Abstract: Aiming at the problem of insufficient monitoring of the production process in tobacco logistics automation workshop,which led to low productivity and difficult control,a production process-oriented visualization and monitoring method was researched,which built a digital twin workshop functional model with multi-level mapping rules from various aspects such as physical equipment and workshop operation process.On this basis,a twin data mapping logic model was established,a unified architecture of real-time data collection and transmission based on S7 protocol was built,the twin model was driven to run synchronously,and a digital workshop monitoring system was designed and developed.Finally,the system is validated by carrying out examples,and the results show that the system can effectively integrate and fuse the workshop production data,and realize the effective monitoring of the whole process of workshop operation.

Key words: tobacco logistics center, digital twin workshop, data driven, S7 protocol, visual monitoring
