Design of 3 d intelligent system based on digital technology of twin,enhance the level of intelligent 3 d.The physical entity and monitoring object of digital twin mapping are managed through the field layer to provide basic data needed for the 3D intelli-gent system.The sensing layer uses temperature sensors and color sensors to perceive the data related to physical entities managed by the field layer.The data storage layer uses distributed files and relational databases to store perceptual data.The function layer uses the missing value of data preprocessing module to process the stored data.Hierarchical modeling module,according to the data pro-cessed after missing values,build the geometric model and attribute model of physical entity,integrate the geometric model and attrib-ute model,get the twin model;The twin model driving unit uses the 3D model driving method to drive the twin model,realize the syn-chronous mapping between physical entity and twin,and obtain the twin data.The simulation and prediction module visually monitors and analyzes the working state of physical entity based on twin data.The action simulation and real-time monitoring results of physical entities are presented to users in real time through the application layer.Experiments show that the system can effectively perceive the relevant data of physical entities and establish the twin model.The system can effectively realize the visual monitoring of physical enti-ties and improve the level of three-dimensional intelligence.
