Problems solved by technology

In the traditional technology, an inductive switch is usually used to detect the external metal to realize the position extension and retraction detection of the side guard. This method has a short detection distance and low reliability
Alternatively, the state of the side guard can also be detected by using a combination of stroke sensors, inclination sensors, pressure sensors and other sensors. This method cannot be applied to complex working conditions in underground mines during cable maintenance and sensor protection.

Abstract

The invention provides a coal cutter hydraulic support side guard state monitoring method and device, and the method comprises the steps: carrying out the defogging of a continuous monitoring image of a coal cutter hydraulic support side guard, and carrying out the edge detail information recovery of the defogged monitoring image, and obtaining a fusion image; identifying a face guard plate area in the fused image through a preset target detection model to obtain a target image; the face guard in the target image is recognized to obtain the angle of the face guard, and the state of the face guard is determined according to the angle, the state of the face guard near the coal mining machine can be monitored in real time by preprocessing the monitoring image and recognizing the image, and the monitoring effect and reliability are improved.

Description

technical field [0001] The invention relates to the technical field of monitoring the state of a side guard of a hydraulic support of a coal mining machine, in particular to a method and a device for monitoring the state of a side guard of a hydraulic support of a coal shearer. Background technique [0002] At present, in order to improve the automation and mechanization of underground mining in coal mines, coal mining machines are usually used to complete underground coal mining operations. In the mining process of the fully mechanized mining face with large mining height, the support side is often opened in time after the shearer cuts coal, and the roof is supported in time to prevent the occurrence of the side or roof fall. During the coal mining process, it is necessary to retract the side guard to avoid interference between the shearer and the side guard of the hydraulic support. With the development of automatic and unmanned coal mining technology in coal mining face,...
