Abstract

The invention provides a hydraulic support control device, which comprises a central processing unit, a video processing unit, a first signal processing unit and a first communication interface, wherein the video processing unit is used for acquiring an image of equipment running state of a mine fully-mechanized working face and a coal-bed excavating image in real time; the central processing unit is used for receiving image information acquired by the video processing unit and transmitting the image information to the first signal processing unit; and the first signal processing unit is used for carrying out encoding and compressing processing on the image information and transmitting the processed image information to a central monitoring system through a first communication interface. The hydraulic support control device provided by the invention integrates hydraulic support control and video monitoring functions, cannot influence pedestrian space and line layout of the working face and is convenient for realizing unmanned automation of the fully-mechanized working face, in particular to unmanned automatic mining of a thin coal seam.

Description

technical field [0001] The invention relates to the field of fully mechanized mining in coal mines, in particular to a hydraulic support control device. Background technique [0002] With the increasing improvement of computer technology and automation technology, the automatic control technology of coal mines has been continuously promoted and applied, which has greatly improved the production efficiency and automation degree of coal mines. Unmanned automatic mining of coal mine fully mechanized mining faces has become another development direction of coal mine automation. At present, the hydraulic support controller already has the functions of manual control, group control, automatic pushing, automatic spraying, sound and light alarm, automatic moving of hydraulic supports, fault diagnosis and other functions. It not only improves the support status of the roof of the working face, ensures the safety of mine production, reduces the labor intensity of workers and improves ...
