AI Technical Summary

Technical Problem

Existing coal mine tunnel cleaning methods are inefficient, labor-intensive, and have poor cleaning effects. In addition, cleaning equipment lacks the ability to perceive dust thickness and evaluate effects in real time, leading to safety hazards and low production efficiency.

Method used

Line laser scanning is used to monitor the dust thickness in the tunnel, and a function is established to determine the relationship between the cleaning effect and the speed and distance of the carrier platform. The posture and movement of the cleaning robot arm are adjusted through adaptive control to achieve automated cleaning.

Benefits of technology

It improves cleaning efficiency and accuracy, reduces labor intensity, reduces safety hazards, ensures safe production in mines, reduces costs and extends equipment life.

Abstract

The present invention relates to an adaptive cleaning control method for dust accumulation in a roadway, and belongs to the field of coal mine roadway cleaning. The method includes three steps: dust thickness monitoring, cleaning effect evaluation, and adaptive cleaning control. Line laser scanning and other means are used to monitor the dust accumulation thickness in the roadway in real time, and the distribution law and sedimentation law of the dust accumulation are obtained. A relationship function is established between the tidal / wet cleaning effect and factors such as the walking speed of the carrier platform, the distance from the left side, and the distance from the right side, and the like. According to the dust accumulation thickness and the cleaning effect evaluation results, the walking speed of the carrier platform and the distance from the two sides, as well as the posture and movement of the cleaning robot arm are automatically adjusted. According to the cleaning effect evaluation results, the walking speed of the carrier platform and the distance from the two sides, as well as the posture and movement of the cleaning robot arm are adjusted to achieve adaptive cleaning. The present invention automatically adjusts the operating parameters of the cleaning equipment according to the dust accumulation thickness and the cleaning effect in the roadway, achieves efficient and accurate roadway cleaning, and reduces roadway dust accumulation.
