Coal mining machine video analyzing and controlling system

Abstract

The invention relates to a video analyzing system, in particular a coal mining machine video analyzing and controlling system. The coal mining machine video analyzing and controlling system comprisesa scraper conveyer, a coal mining machine, and a spill-plate. The system is characterized in that a track trolley is installed on the spill-plate; a coal recognition device is installed on the track trolley, and the track trolley is connected to the coal mining machine through a connection rod. The images collected by a camera are processed by image analyzing software to determine the boundary between a coal bed and rocks, the vertical movement of the coal mining roller of the coal mining machine is controlled to avoid the rocks in the digging working surface automatically; the coal mining machine can carry out digging automatically without human supervision; the safety of coal mines is improved, and the labor strength is reduced.

Description

technical field [0001] The invention relates to a video analysis system, in particular to a video analysis control system for a coal mining machine. Background technique [0002] The coal shearer is one of the main equipments of the comprehensive mechanized coal mining face. At present, the coal shearer rides on the flexible scraper conveyor to move back and forth for mining work. In order to prevent the mined coal from falling on the outside of the scraper conveyor, a A coal shield is installed on the outside of the scraper conveyor. [0003] The working condition of the shearer drum on the mining face is observed by the on-site personnel with naked eyes. When the pick in the shearer drum cuts into the roof or floor rock, the wear and damage of the pick will reduce the life of the machine. The cutting of the teeth into the rock will cause a sharp increase in the friction between the pick and the rock, resulting in local high temperature, which may detonate the gas and brin...

[0003] The working condition of the shearer drum on the mining face is observed by the on-site personnel with naked eyes. When the pick in the shearer drum cuts into the roof or floor rock, the wear and damage of the pick will reduce the life of the machine. The cutting of the teeth into the rock will cause a sharp increase in the friction between the pick and the rock, resulting in local high temperature, which may detonate the gas and bring great hidden dangers to the safety of the mining site. The hydraulic system adjusts the height of the shearer drum so that the picks in the drum leave the rock, which leads to low working efficiency of the shearer, high labor intensity for operators, and poor working environment.
