Simply put, digital twinning is to complete the mapping of physical objects, systems and data in virtual space, thus reflecting the whole life cycle process of the corresponding entities, mining historical laws, monitoring real-time status and predicting future trends. The application of digital twin technology in physical factories will greatly promote the reform of product design, production, management and maintenance.

Digital twinning is the description, diagnosis, prediction and decision-making of physical space by using information technologies such as perception, calculation and modeling, so as to realize the interactive mapping between physical space and virtual space.

Intelligent manufacturing: Based on the deep integration of the new generation of information and communication technology and advanced manufacturing technology, it runs through all aspects of manufacturing activities such as design, production, management and service, and has the functions of self-perception, self-learning, self-decision-making, self-execution and self-adaptation. The architecture of intelligent manufacturing system describes the activities, equipment and characteristics involved in intelligent manufacturing from three dimensions: life cycle, system level and intelligent characteristics.
