Positioning device and method of coal mining machine in full-mechanized mining face

Abstract

The invention provides a positioning device and method of a coal mining machine in a full-mechanized mining face, and belongs to an autonomous positioning device and method of the coal mining machine. The positioning device of the coal mining machine is installed in a machine body, and comprises a rubber vibration damping base, a triaxial laser gyroscope, a triaxial optical fiber accelerometer, a positioning device microprocessing unit, and a positioning device anti-explosion shell , wherein the positioning device anti-explosion shell is connected above the rubber vibration damping base, and the triaxial laser gyroscope, the triaxial optical fiber accelerometer and the positioning device microprocessing unit are installed in a shell consisting of the rubber vibration damping base and the positioning device anti-explosion shell. Real-time acceleration values in three directions are measured by using the triaxial optical fiber accelerometer, and real-time angular velocities in the three directions are measured by using the triaxial laser gyroscope; thus, data of a sensor is sampled to a DSP (Digital Signal Processor) to determine the initial velocity and position, and the displacement and angular deflection of the coal mining machine along the three directions are obtained through an integral operation. The positioning device has the advantages of compact structure, simple method, safety, reliability and simplicity and convenience for installation and operation.

Description

technical field [0001] The invention relates to an autonomous positioning device and a positioning method for a coal mining machine, in particular to a positioning device and a positioning method for a coal mining machine in a fully mechanized mining face. Background technique [0002] The coal shearer is the main equipment for coal dropping and coal loading in the fully mechanized mining face. In the process of comprehensive mechanized coal mining, in order to realize the automation of the hydraulic support and the machine, it is necessary to realize the high-speed and precise positioning and navigation of the shearer. When the real-time position and attitude of the shearer can be confirmed, the support control unit can issue corresponding control commands in time according to the obtained position information of the shearer, and control the timely support and pushing procedures of the support, so as to realize the coordinated automation of the three machines. Therefore, sh...
