Embodiment Construction

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0053] The present invention provides a control method based on a three-dimensional real-time model of stockpile layering, and its specific process is as follows figure 1 shown, including:

[0054] S100: During the process of stockpiling or retrieving, use the laser radar to collect the 3D point cloud data of each layer of the stockpile in real time.

[0055] Install lidar at appropriate locations on the bucket wheel stacker-reclaimer. When the stacker-reclaimer is stacking or reclaiming the material pile, the working surface is raised or lowered layer by layer. Therefore, the laser radar can be used to perform three-dimensional scanning on each layer of the material pile to realize the material pile Real-time collection of point cloud space coordinate data of each layer of working face.

[0056] S200: Based on the point cloud spatial coordinate data of th...

Abstract

The invention discloses a control method and system based on a material pile layering three-dimensional real-time model. The invention can establish a material pile layering three-dimensional real-time model, reflect morphological feature types of layers of a working surface of a material pile based on the model, and achieve furthermore a more matched and finer stacker-reclaimer equipment control mode based on the morphological feature types of the material pile.

Description

technical field [0001] The invention belongs to the technical field of intelligent equipment for a coal stockyard, and in particular relates to a control method and system based on a three-dimensional real-time model of stockpile layering. Background technique [0002] The coal yard is a large space for stacking coal, and it is an essential part of thermal power plants and other units. Coal stockyards generally need to be equipped with large-scale facilities such as bucket wheel stackers and reclaimers to realize the stacking and reclaiming of coal materials. [0003] In recent years, with the in-depth application of digital and intelligent technologies in traditional industries, an important research and development direction in this field is to take the bucket wheel stacker and reclaimer as the implementation object, using positioning technology, control technology, laser scanning technology, three-dimensional graphics processing And information communication and other te...
