Abstract:
The continuous stripping process in open-pit mining has the characteristics of large scale, high production efficiency, and low transportation costs, and has played a key role in the open-pit mining process. Scientific control and management of mechanical equipment based on the actual geological conditions of open-pit mining sites can effectively improve the efficiency of stripping processes and other operations. In order to further improve the production efficiency of bucket wheel excavator and improve the automation degree of on-site production, the fully automatic control technology of bucket wheel excavator in open pit mine is developed based on 5G industrial Internet, satellite positioning and LiDAR technology. Construct a three-dimensional coordinate system for the stripping working face based on satellite positioning system, and complete the forward and inverse kinematics analysis of the wheel bucket excavator according to the D-H parameters (Denavit-Hartenberg parameters) of the multi-link series robot. By using a control strategy calculation program, the point cloud data collected by the LiDAR device on the stripping working face is fitted in 3D to complete the 3D modeling of the stripping working face. Based on the stripping process of the mining belt, an automatic mining control strategy is generated and sent to the PLC controller in the form of an instruction set to guide the wheel bucket continuous system to complete automatic operations, ultimately achieving the goal of fully automatic control of the wheel bucket excavator.
