Intelligent speed regulation system and method for complete set of coal mine transportation equipment based on machine vision

Abstract

The invention discloses an intelligent speed regulation system and an intelligent speed regulation method for coal mine complete transportation equipment based on machine vision. The intelligent speedregulation system comprises an explosion-proof camera group, wherein the explosion-proof camera group is composed of a horizontal explosion-proof camera and a vertical explosion-proof camera, the horizontal explosion-proof camera is arranged at one side of a transfer machine, the vertical explosion-proof camera is arranged just above the transfer machine, the horizontal explosion-proof camera andthe vertical explosion-proof camera are positioned in the same plane perpendicular to the transfer machine, a number of LED beacons is four, and the four LED beacons are symmetrically arranged on both sides of a machine body of the transfer machine; and the horizontal explosion-proof camera and the vertical explosion-proof camera are connected with a remote computer control center, and the remotecomputer control center is connected with a transportation system controller. The intelligent speed regulation system and the intelligent speed regulation method adjust operation speeds of a scraperconveyor and the transfer machine according to an instantaneously conveyed coal amount measured through image shooting, so that the instantaneously conveyed coal amount of a belt type conveyer is always in a standard range of instantaneously conveyed coal amounts of the system, and prevent the belt type conveyer from encountering idle running, coal piling, material scattering, off tracking and thelike.

Description

technical field [0001] The invention relates to an intelligent speed regulation system and method, in particular to an intelligent speed regulation system and method for coal mine complete transportation equipment based on machine vision. Background technique [0002] On the fully mechanized mining face of the coal mine, the transportation of coal materials is mainly completed by the cooperative work of the scraper conveyor, the reloader and the belt conveyor. The coal produced by the shearer is cut and transported to the loader by the scraper conveyor, then transported to the belt conveyor after being transported by the loader, and finally transported to the ground. [0003] On the current fully mechanized coal mining face, since the speed of the scraper conveyor, reloader and belt conveyor remains constant during operation, when the amount of coal cut by the shearer changes, the As a result, the amount of coal transported by the scraper conveyor changes, and then the amou...

AI Technical Summary

Problems solved by technology

When the instantaneous amount of coal delivered by the reloader is greater than the maximum value of the system's instantaneous coal delivery standard range, the belt conveyor is prone to a series of problems such as coal piles, material spreading, deviation, etc., which greatly reduces the working performance of the belt conveyor and service life

In addition, if the instantaneous coal delivery volume of the reloader is less than the minimum value of the system's instantaneous coal delivery standard range, the belt conveyor's loading conditions will be wasted, thereby reducing the overall coal transportation volume of the coal mine.
