Digital twins are widely used in smart manufacturing,aerospace,smart healthcare,and other fields.Among them,building visual models is one of the key technologies of digital twins.Taking the material sorting device as the object,the construction of the virtual device is completed through SolidWorks software.The Unity platform is used to establish ren-dering and behavioral logic models.Based on the S7 communication protocol,the data interaction between Siemens PLC and the Unity platform is realized,and the visual model is built.Finally,with the material sorting device as the control ob-ject,the control system combining virtual and real is successfully constructed through PLC control and combined with the visualization model.Experiments show that the visualization model has the same physical properties and functions as the physical entity,and the model construction method is versatile,which can provide virtual model construction solutions.
