Intelligent control system and method for scraper reclaimer

Abstract

The invention provides an intelligent control method for a scraper reclaimer. The method specifically includes the steps of establishing a three-dimensional model of a material pile, wherein outer contour data of a material pile is obtained through a 3D laser scanner, the three-dimensional model of the material pile is established through a triangle reconstruction algorithm, the curve of the highest point and the curve of the bottom edge of the material pile in the three-dimensional model are extracted, and the slope angle of the material pile and the volume parameter of the material pile arecalculated; intelligently controlling the material leveling process, wherein the scraper tilt angle, the material leveling start point and the material leveling end point of the scraper reclaimer formaterial leveling are set according to the curve of the highest point and the curve of the bottom edge; and intelligently controlling the reclaiming process, wherein the reclaiming flow, the reclaimerpitch angle, the start point and the end point of the scraper reclaimer for reclaiming are set according to the slope angle of the material pile and the volume of the material pile. The intelligent and automatic control over the material leveling and material reclaiming process of the scraper reclaimer is realized, the technical problem that the scraper reclaimer cannot automatically perform material leveling is solved, the average time of one time of material leveling is greatly shortened, the material flow in the reclaiming process is continuous and stable, and the reclaiming efficiency iseffectively improved.

Description

technical field [0001] The invention relates to an intelligent control system and method for a scraper reclaimer, and the specific design relates to an intelligent control system and method for a scraper reclaimer based on a pile model.

Problems solved by technology

[0004] With the development of instrument detection and automatic control technology, the automatic control level of the scraper reclaimer has achieved a certain development, and the partial automatic production of the reclaiming process has been realized. However, during the reclaiming process with a fixed stroke, the reclaimer has idling phenomenon. The material flow is unstable, and there is a phenomenon of material reclaiming interruption. In order to ensure the stability of the production of down
