Abstract: Due to the problems of long research and design cycle of stacker,and low rate of information collection and working efficiency,a visual design method of stacker model based on digital twin was proposed. Combined with the technology of digital twin,a virtual debugging platform of stacker model was built by OPC unified architecture technology based on the five-dimensional model of digital twin,which realizes real-time communication and data interaction between the physical model and the digital model of stacker.The visual monitoring and optimization of the working state of the stacker were realized through the data collection of the working state of the stacker physical model,which verifies the feasibility of the visual design method of stacker model based on digital twin.This study can provide a reference for the design and transparency operation of stacker.

Key words: digital twin, stacker, intelligent control, visualization
