Abstract: With the requirements of real-time visual monitoring,health management and fault diagnosis of the intelligent workshop,the framework and route of digital twin workshop based on real-time date driven were proposed.A modular and generalized digital twin workshop system was constructed by setting up a virtual simulation environment for high-fidelity mapping of real physical behavior and adopting the data management method for event response.Furthermore,the key technologies such as heterogeneous multi-source data acquisition and management,virtual simulation environment of real physical behavior,and real-time data-driven method for event response were elaborated in detail.The prototype system was designed,and its feasibility was successfully verified by the vehicle radar workshop,which provided a key support for the application of digital twinning technology in the field of intelligent manufacturing.

Key words: digital twin, data driven, high-fidelity mapping, event response, intelligent workshop
