Device and method for detection of absolute positions and attitudes of hydraulic supports of fully mechanized mining face

Abstract

The present invention discloses a device and a method for detection of absolute positions and attitudes of hydraulic supports of a fully mechanized mining face. The device comprises a sensor group, adata processor and a target. The sensor group comprises a first reference photoelectric tracer, a second reference photoelectric tracer, a local photoelectric tracer and a dual-axis level. The detection method comprises the following steps of: 1, arrangement of reference points and installation of reference photoelectric tracers; 2, arrangement of transition points and installation of the local photoelectric tracer; 3, establishment of an east-north-up (ENU) geographic coordinate system and obtaining coordinates of the reference points; 4, obtaining of coordinates of each transition point according to a reference point A; 5, correction of coordinates of each transition point; and 6, obtaining of absolute positions and attitudes of the hydraulic supports. The device and the method for detection of absolute positions and attitudes of hydraulic supports of the fully mechanized mining face can detect absolute positions and attitudes of the hydraulic supports in real time, lay the foundation of construction of an accurate fully mechanized mining face geographic information system, and lay the groundwork for alignment of the fully mechanized mining face, rectification of the hydraulic supports and intelligent control of the fully mechanized mining face.

Description

technical field [0001] The invention belongs to the technical field of absolute position and attitude detection of a fully mechanized mining face hydraulic support, and in particular relates to a fully mechanized mining face hydraulic support absolute position and attitude detection device and method. Background technique [0002] Intelligent and unmanned fully mechanized mining face is an effective way for coal mines to reduce the accident rate, improve efficiency and enhance competitiveness. The hydraulic support is one of the important equipment in the fully mechanized mining face. It mainly consists of the top beam, the column base, the push jack and the control valve. Workspace. However, there are a large number of hydraulic supports in the fully mechanized mining face. During the mining process, the working face is continuously advanced, and the position of the hydraulic supports changes dynamically. fundamentals of humanization. [0003] The absolute position of th...
