Method, device and system for identifying support movement state of hydraulic supports

Abstract

The embodiment of the invention discloses a method, device and system for identifying the support movement state of hydraulic supports and relates to the field of coal mine operation safety guarantee.The method comprises the steps of obtaining real-time video images, and conducting preliminary screening, so that pre-detection images are obtained; determining the advancing direction and a predetermined detection area of a coal mining machine; judging whether the number of the hydraulic supports in the predetermined detection area is greater than or equal to a preset value T or not, and conducting analysis on the support movement state of the hydraulic supports; when it is determined that the T hydraulic support in the predetermined detection area is not moved, generating warning information; and when it is determined that the T hydraulic support in the predetermined detection area is moved, double checking whether all the hydraulic supports are moved or not with the T hydraulic support in the predetermined detection area being the start point, and if any hydraulic support is not moved, generating warming information. By means of the method, device and system for identifying the support movement state of the hydraulic supports, the problems that at present, detection of the support movement state of hydraulic supports is only dependent on manual work, and the supportmovement state of the hydraulic supports cannot be known in time and precisely are solved.

Description

technical field [0001] The embodiments of the present invention relate to the field of coal mine operation safety assurance, and in particular to a method, device and system for identifying the moving state of a hydraulic support. Background technique [0002] During the coal mining process, the coal on the coal wall is broken by the shearer and then falls into the scraper conveyor on the working face, and the coal is transported to the surface through the scraper conveyor, reloader, belt and other coal transportation equipment. The first production site of underground coal is fully mechanized mining face, and hydraulic support is the support equipment of fully mechanized mining face, which supports the roof of fully mechanized mining face. After the coal shearer cuts coal, the operator operates the hydraulic support to move the hydraulic support forward in time to support the roof exposed after the coal cutting, which is called the timely movement of the hydraulic support. ...
