Device and method for hydraulic support gesture detection

Abstract

The invention discloses a device and a method for hydraulic support gesture detection. The device comprises a data acquisition device, a signal transmission module, a signal processing module and a display module. The water column pressure is measured through a pressure sensor, the perpendicular height of a hose pipe is further determined, a vertical height difference of four corners of a rectangular top plate of a hydraulic support and a vertical height difference of four corners of a rectangular bottom plate are obtained, then a long side inclined gesture angle and a wide side inclined gesture angle of the rectangular bottom plate and a long side inclined gesture angle and a wide side inclined gesture angle of the rectangular top plate are obtained by utilizing a trigonometric function through the vertical height differences and known long side lengths and wide side lengths of the rectangular bottom plate and the rectangular top plate, and finally, by adopting the two angles as difference values, the long side inclined gesture angle and the wide side inclined gesture angle, relative to the rectangular bottom plate, of the rectangular top plate are obtained; finally the real-timegesture detection of the hydraulic support top plate and the bottom plate is realized. According to the device and the method provided by the invention, the real-time gesture angle of the hydraulic support can be accurately detected, so that the stable operation of the hydraulic support is ensured.

Description

technical field [0001] The invention relates to a device and method for attitude detection of a hydraulic support, belonging to the technical field of hydraulic support detection. Background technique [0002] With the rapid development of energy technology, my country's energy structure is gradually diversifying and rationalizing. Although the proportion of coal in my country's energy has declined, it still does not affect the status of coal as the main energy source in China. In coal production, the hydraulic support is an important equipment for fully mechanized coal mining. The hydraulic support uses high-pressure hydraulic oil as the supporting power, and plays the role of support and protection in the coal mine. In today's coal mining, it is widely used. [0003] Coal mine fully mechanized mining automation is developing in the direction of unmanned and less humanized. In order to achieve safe development, it is necessary to monitor the attitude of the hydraulic suppo...

Problems solved by technology

If an inclination sensor is used to detect the attitude angle of the top and bottom hydraulic supports, the inclination error will accumulate and increase, and the attitude detection of the hydraulic support by the inclination sensor will distort the sudden change of the angle, and the accuracy is generally not high
