Embodiment Construction

[0039] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

[0040] Some of the words mentioned in the embodiments of the present disclosure are illustrated below.

[0041] See attached figure 1 , The invention relates to a fully mechanized mining system in a coal mine working face. The fully mechanized mining system mainly includes a hydraulic support, a scraper conveyor and a coal shearer. Among them, the coal mining machine moves on the coal mining machine track of the scraper conveyor to complete ...

Abstract

The invention provides a vision-based method for detecting the straightness of a fully mechanized mining face. The method includes: installing a vision system on a rapid inspection platform of the working face. The camera of the vision system is arranged at the end of the inspection platform, and the nose of the camera is parallel to the walking track, and should be slightly inclined downward as much as possible. Shoot videos during the rapid movement of the inspection platform, and try to be as stable as possible to ensure that the track of the inspection platform's walking mechanism always appears in the shooting screen. When the walking mechanism of the inspection platform circulates along the working face at a relatively fast speed, its walking trajectory is photographed, and then the movement trajectory of the walking mechanism of the inspection platform is calculated based on the visual algorithm, so as to detect the straightness of the fully mechanized mining face and realize the comprehensive Automatic straightening of mining face.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to a method and system for detecting the straightness of a fully mechanized mining face in an underground coal mine. Background technique [0002] The fully mechanized mining face is composed of shearer, scraper conveyor, hydraulic support and other equipment. The scraper conveyor is composed of a section of a chute connected. The connecting hole of the scraper conveyor and the hydraulic support push rod connection head are fixed and connected by pins, and the telescopic action of the jack is pushed through the hydraulic support on the working surface. Realistic scraper conveyor of the mobile. Multiple hydraulic supports are arranged in sequence on the working surface, and their respective positions are constrained by the scraper conveyor on the working surface, but their mutual positions are not constrained, which is a semi-floating system. During work, in order to realize the normal o...
