Embodiment Construction

[0032] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0033] figure 1 It is the flowchart of the reclaiming method provided according to the present invention, as figure 1 As shown, the reclaiming method provided by the present invention may include: at step 10, obtaining a three-dimensional model of the stockpile; at step 11, identifying the three-dimensional model to determine the reclaiming starting point and reclaiming end point; and at step 12, Control the reclaimer to reclaim from the starting point of reclaiming to the end point of reclaiming. In this way, the control process of the reclaimer can be reasonably controlled, the stability and reclaiming efficiency of the reclaiming operation are improved, and...

Abstract

The invention relates to the field of control engineering and discloses a material pile modeling method and device. The material pile modeling method comprises steps of: acquiring the discharged point of materials according to the angle of pitch of a stacker cantilever and the speed of a cantilever belt; acquiring an angle of repose according to a material characteristic; acquiring the volume of the discharged materials; and establishing a material pile model according to the angle of repose and the volume. The method and device may accurately establish the material pile model, increase efficiency for subsequent material-acquiring engineering, and enhance operating stability.

Description

technical field [0001] The invention relates to the field of control engineering, in particular to a stockpile modeling method and a stockpile modeling device. Background technique [0002] The reclaimer is an important equipment in the bulk material transportation machinery. Its main function is to take the materials in the yard (generally referring to coal or ore, and coal is used as an example below) to the belt conveyor, and then transport it to the loading area through the belt conveyor. Shipping on board the ship. Generally speaking, the reclaimers in China are manually reclaimed. Every time the reclaimer operates, the driver observes the shape of the coal pile with his eyes. First, the coal pile is layered (generally divided into three layers) to determine the The bucket wheel of the reclaimer reclaims the first layer of the coal pile and roughly determines the specific entry point; then manually controls the walking, turning, pitching and other actions of the reclai...
