Modeling of cross-scale human activity for digital twin workshop
Digital Twin Workshop(DTW), as an important approach to digitalization and intelligentization of workshop, has gained significant attention in manufacturing industry. Currently, digital twin models for manufacturing resources have progressed from theoretical research to practical implementation. However, as a crucial component of workshop, modeling of human activity in workshop still faces challenges due to the autonomy and uncertainty of human beings. Therefore, we propose a comprehensive approach to the modeling cross-scale human activity in digital twin workshop, which comprises macro activity and micro activity. Macro activity contains human’s occupation and spatial positions in workshop, while micro activity refers to real-time posture and production actions at work. In this paper, we build and integrate macro activity digital twin model and micro activity digital twin model. With the combination of closed-loop interaction between virtual models and physical entities, we achieve semantic mapping and control of production activities, thereby facilitating practical management of human activity in workshop. Finally, we take certain factory’s manufacturing workshop as an example to introduce the application of the proposed approach.
