Problems solved by technology

[0006] The purpose of the present invention is to provide a coal mining machine absolute positioning device and method that integrates geological environment information to solve the problem of large positioning errors in the existing coal mining machine positioning method, which is difficult to adapt to the complex and harsh underground coal mining environment and mining environment. The continuous change of coal route and coal rock properties will cause disturbance to the movement of the shearer, resulting in inaccurate positioning

Abstract

The invention provides a geological environment information-fused absolute positioning device and method for a coal cutter, which belongs to absolute positioning devices and methods for coal cutters. An explosion-proof enclosure is fixed on the body of a coal cutter. A coal cutter positioning device is arranged in and connected with the explosion-proof enclosure and comprises an aspect sensor, an inertial measurement unit, a vibration sensor, an ultra wide band (UWB) wireless positioning system sensor and a positioning data microprocessing unit, wherein the output ends of the aspect sensor, the inertial measurement unit, the vibration sensor, the UWB wireless positioning system sensor and a shaft encoder are connected with the input end of the positioning data microprocessing unit, the output end of the positioning data microprocessing unit is connected with the input end of an industrial control computer through a data output interface, and positioning labels are arranged on the coal wall of a roadway and a hydraulic support at an equal interval. The invention has the following advantages: geological environment information and the coal cutter are integrated in a same space-time system, the operation route of the coal cutter is planned, footage and mining height of the coal cutter are adjusted, situations possibly incurring danger are avoided in advance, and the other advantages of practicality, safety, reliability and convenient installation and operation are obtained.

Description

Technical field [0001] The present invention involves an absolute positioning device and method of a coal mining machine, especially a absolute positioning device and method of combining the coal mining machine that integrates geological environment information. Background technique [0002] The coal mining machine is one of the core equipment of the comprehensive mining work surface and undertakes the task of coal drop and coal installation.At present, the three machines of comprehensive mining work surfaces: coal mining machines, scraper conveyors and hydraulic brackets need artificial intervention.In the process of integrated mechanization and coal mining, it is necessary to realize coal mining and uninhabited coal mining, and must be coordinated by three coal mining machines, scrape conveyors, and hydraulic brackets.To realize the coordinated automation of the three machines, the problem of hydraulic brackets and machine automation during the coal cutting process of the coal ...
