The present invention provides a working face end socket calibration device and method based on a UWB (Ultra-wideband) coal mining machine, belonging to the technical field of downhole coal mining machine end socket calibration. The body of the coal mining machine is provided with a location device explosion-proof enclosure, an inertial navigation location device and a UWB location terminal sensorare installed in the location device explosion-proof enclosure, an UWB base station is fixed on a support, the support is installed on a screw rod, the screw rod is arranged on a guide rail, the screw rod is connected with a motor through a coupler, and a shaft encoder is connected on the motor; a support body is arranged at the lower portion of the guide rail; the inertial navigation location device, the UWB location terminal sensor and the shaft encoder are connected with a computer through a data microprocessor unit; after the UWB location system completes calibration of the coal mining machine at the end socket, the UWB base station moves along a crossheading tunnel to prepare for next calibration to form an 'one-tool-one-calibration' end socket calibration system for the coal miningmachine so as to reduce the location errors of the coal mining machine and improve the location precision of the coal mining machine, and therefore, the operation is convenient, and the practicabilityis high.
Description
technical field [0001] The invention relates to the technical field of calibration of an end of an underground coal mining machine, in particular to a device and method for calibrating an end of a working face of a coal mining machine based on UWB. Background technique [0002] The automation and intelligence of the fully mechanized mining face in coal mines is a key step to realize unmanned, safe and efficient mining in the mine, and it is also an important part of developing digital mines and improving the informatization and automation level of mine electromechanical equipment. In order to realize the less manned and unmanned fully mechanized mining face, the intelligentization of the "three machines" of the fully mechanized mining face, namely the shearer, scraper conveyor and hydraulic support, is one of the key technologies. The three-dimensional positioning of space is the core technology to realize the intelligent fully mechanized mining face. For the positioning of...
