Abstract

The invention discloses a machine vision-based method and device for online detecting multi-rope multi-layer wound rope guiding states. The method comprises the following steps of: setting an industrial camera at each rope guiding area; carrying out inter-frame template image matching on an acquired image sequence; obtaining a final target tracking frame; automatically tracking the rope guiding state by utilizing judgement carried out on position information of the target tracking frame; and when transition among a plurality of ropes is out of sync or a single rope guiding area has a rope disorder fault, carrying out real-time detection and giving alarm information. According to the method and device, the condition that a single rope is highly stressed as the transition is out of sync or abrasion of steel wire ropes is increased due to rope disorder is avoided, and benefit is brought to ensure the safe operation of ultra-deep well enhancing equipment and decrease the economic loss.

Description

technical field [0001] The invention belongs to the field of visual detection, and in particular relates to an online detection method and device for multi-rope multi-layer winding and arranging state based on machine vision. Background technique [0002] At present, the mining of mineral resources in our country is still in the shallow layer due to technical limitations. With the depletion of shallow mineral resources, the country has proposed the goal of mining mineral resources to the deep layer. The multi-rope multi-layer winding hoist is proposed by experts in the field of mine hoisting. A kind of hoisting equipment that satisfies the ultra-deep and high-speed working conditions. In order to ensure the safe operation of the equipment and avoid the mutual extrusion of the steel wire ropes when the ropes are in disorder, the wire ropes are worn out. Real-time monitoring of the synchronicity of the transition between the layers of the steel wire rope. When a fault occurs, ...
