AI Technical Summary

Technical Problem

In existing coal mine drill arm operations, coal dust and rock cuttings intrude into the joints, causing rotational obstruction, increased wear, and even jamming, affecting drilling efficiency and equipment lifespan. Existing control systems have failed to effectively cope with dynamic particle splashing interference.

Method used

A particle detection device is set up to acquire particle parameters, identify the particle posture interference range of the joint nodes, construct the reverse posture adjustment range, and optimize the angle adjustment of the joint nodes through distributed collaborative control to avoid particle intrusion.

Benefits of technology

By using particle detection and distributed control, particle intrusion into joints is prevented, reducing wear and jamming risks, and improving drilling efficiency and equipment reliability.

Abstract

The invention relates to the technical field of drill boom control, and provides a coal mine drill boom angle adjusting method and system based on distributed control. The method comprises the following steps: arranging a particle detection device, and obtaining particle detection parameters; acquiring a joint node, and identifying a particle attitude interference interval of the joint node based on the particle detection parameter; constructing a corresponding reverse attitude adjustment interval; and a drilling task path is determined, a reverse attitude adjustment interval is taken as a constraint, distributed cooperative control optimization is carried out on joint nodes according to the task path, angle adjustment parameters are obtained and used for angle adjustment, and therefore the problems that when an existing coal mine drill arm works, coal dust and rock debris particles intrude into the joint parts, rotation retardation is caused, abrasion is aggravated and even jamming is caused, and the working efficiency is poor are solved. The technical problems of influence on drilling efficiency and equipment service life due to particle detection and distributed cooperative control in the prior art are solved, and the technical effects of preventing particles from invading joints, reducing joint abrasion and jamming risks and improving drilling efficiency and equipment operation reliability are achieved through particle detection and distributed cooperative control, construction of reverse attitude adjustment constraints, prevention of particles from invading the joints, reduction of joint abrasion and jamming risks and improvement of drilling efficiency and equipment operation reliability.
