A device and method for automatic height adjustment of a shearer drum based on image recognition

Abstract

The invention discloses a coal mining machine roller automatic height regulating device based on image recognition. The device comprises an image pickup module, an image recognition processing module, a coal mining machine rocker arm height regulating module, an image pickup monitoring module and a roller track tracking sensor module, wherein the image pickup module is used for shooting a coal mining working face coal rock image and putting the image into the image recognition processing module and the image pickup monitoring module; the image recognition processing module is used for recognizing the coal mining working face coal rock image boundary, and inputting the recognizing result into the coal mining machine rocker arm height regulating module; the coal mining machine rocker arm height regulating module is used for controlling the automatic height regulation of a coal mining machine roller; the image pickup monitoring module is used for monitoring whether the coal mining machine roller generates contact with rock stratums or not during the whole coal working face cutting; the roller track tracking sensor module is used for performing path detection calculation on a coal mining machine rocker arm, and comparing the fitting degree of the coal rock interface in the collected image. The device has the advantages that the coal mining efficiency is high and the reliability is high.

Description

technical field [0001] The invention relates to a device and method for automatically adjusting the height of a shearer drum, specifically identifying the coal-rock interface through an image recognition method and outputting an identification signal to control the automatic height adjustment of the shearer drum, belonging to the technical field of automatic mining equipment. Background technique [0002] my country is a big country in mining and consumption of coal mines, and the drum shearer, as the main mining equipment, plays a vital role in coal mining. However, due to the harsh working conditions and the low level of reliability and automation of coal mining machines, coal production is still a high-risk industry. Therefore, it is urgent to improve the automation level of the fully mechanized mining face, realize "mechanization replacement, automation reduction", improve the working conditions of coal mining workers, and reduce labor intensity. For the automation of f...

AI Technical Summary

Problems solved by technology

In the complex environment of the underground, many methods have certain limitations, or the recognition accuracy cannot meet the requirements, cannot provide conditions for the automatic control of the coal shearer, or are easily disturbed by the external environment, and the versatility is not strong, so they cannot It is very suitable for unmanned fully mechanized mining face and accelerates the development of automatic mining equipment
