Problems solved by technology

[0003] The Chinese invention patents with patent numbers 201210366865.0, 201110209300.7, and 200910224776.0 respectively proposed the method of measuring the height of the hydraulic support top beam of the fully mechanized mining face by using liquid level pressure, angle sensor and cable distance sensor, but they all have their own The disadvantages are as follows: the liquid level pressure method is difficult to arrange in a complex downhole environment, which leads to its low degree of realization; although the angle sensor method is simple in layout, it can only measure angles within 30°. When the angle of the beam exceeds

Abstract

The invention discloses a system for measuring a top beam support height and attitude of a hydraulic support and a method thereof. The system is composed of a machine vision module and an attitude compensation module in a cooperative positioning with the machine vision module. The machine vision module measures the angle and height of a hydraulic support top beam relative to a hydraulic support base plate; and an MEMS tilt angle sensor in a height and tilt angle compensation module measures an angle value of the hydraulic support base plate relative to a horizontal plane and then the top beam support height and angle values measured previously are compensated, thereby obtaining final angle and height values of the hydraulic support top beam. With the machine vision module, installation becomes convenient and the structure is simple; measurement can be carried out without arranging any complex mechanism at a hydraulic support; the a hydraulic support motion is not affected; and the normal work of the hydraulic support is guaranteed.

Description

technical field [0001] The invention relates to a measuring system and a method of a hydraulic support, in particular to a measuring system and a method for measuring the height and posture of a top beam of a hydraulic support. Background technique [0002] With the continuous progress and development of mechanized coal mining technology, coal mines at home and abroad are beginning to transform towards "unmanned" or "fewer people" coal mining face. With the further development of "fewer people" and "unmanned" fully mechanized mining face, the acquisition of hydraulic support information of fully mechanized mining face becomes more and more important. Usually, the support height of the hydraulic support is the same as the roof height of the fully mechanized mining face, so the support height of the hydraulic support can indirectly reflect the roof height of the fully mechanized mining face. At the same time, the hydraulic support is an important part of the three-machine mat...
