In order to solve the problem of energy consumption optimization during the operation of belt convey-or,an intelligent belt speed optimization model of belt conveyor is established based on digital twin.Firstly,a vir-tual model and data model of the belt conveyor based on digital twins are established.It is divided into three sta-ges to establish a high-fidelity virtual model of the belt conveyor from the perspectives of geometry,physics,and behavior.The data model is established based on the actual operation of the conveyor,which is developed to real-ize real-time mapping of the belt conveyor operation process.Secondly,by analyzing the influencing factors of belt conveyor operation energy consumption,a belt conveyor energy consumption calculation model is established.Based on the energy consumption calculation model,a belt conveyor energy consumption prediction model is es-tablished by using PSO-RBF,and the accurate prediction of energy consumption of belt conveyor is realized.Fi-nally,a belt conveyor belt speed control model is established in three stages to achieve belt conveyor energy con-sumption optimization based on digital twins.
