Abstract: As a key link in production,the intelligent level of workshop scheduling management plays an important role in the construction of digital workshop.In the existing workshop scheduling management,the information release medium is mainly two-dimensional physical kanban in public space,which limits the intelligent development of workshops.To meet the requirements of workshop scheduling management,Mixed Reality (MR) technology and digital twin technology were introduced to propose a six-dimensional model of MR digital twin workshop scheduling intelligent management system.On this base,a framework of MR-based digital twin workshop scheduling intelligent management system was established;the visualization technology of scheduling information for MR-based digital twin workshop was studied,and a full-element information model for workshop scheduling process was constructed,which provides a unified data foundation for workshop scheduling visualization management and intuitively expresses of workshop information;the multi-modal interactive information acquisition technology for MR-based digital twin workshop was explored,and a multi-modal interactive information intelligent acquisition strategy in MR application was proposed to achieve efficient information acquisition;finally,through human-computer interaction experiments,three typical scenarios of production scheduling were taken as examples to verify the performance of the system proposed.The results show that the proposed system can significantly improve the efficiency of workshop scheduling and enhance user experience.
