Abstract

The invention discloses an inertial navigation-laser scanning integrated coal mining machine positioning device and method, and belongs to coal mining machine positioning devices and methods. The positioning device adopts the structure that a positioning device explosion-proof housing and a laser signal receiving module are fixed on the main body of a coal mining machine; an inertial navigation positioning device and a laser scanning microprocessor are mounted in an explosion-proof device; when the coal mining machine works, the inertial navigation positioning device acquires the real-time angular rate and the real-time through a sensor, and transmitting the data to the laser scanning microprocessor; in a laser scanning device, a laser scanning base station is arranged in the working area of the coal mining machine, a laser signal of the laser scanning base station is received by the laser signal receiving module, and meanwhile the data are transmitted to the laser scanning microprocessor; the laser scanning microprocessor is connected with an upper computer through a serial port. Respectively acquired positioning data are transmitted to a coal mining machine positioning control system for data processing, and the position of the coal mining machine is confirmed according to an algorithm integrating the least square method and the neural network algorithm, so as to realize precise positioning; the positioning device and method have the advantages of being precise in positioning, safe and reliable.

Description

technical field [0001] The invention relates to a positioning device and method for a coal shearer, in particular to a positioning device and method for a coal shearer integrated with inertial navigation and laser scanning. Background technique [0002] Positioning technology refers to the technology of measuring the target by some means, and then obtaining the target position information. With the continuous advancement of modern technology, the position of positioning is getting higher and higher in production and life. In many positioning fields, the positioning of various equipment in mines is slowly entering people's field of vision. Due to the frequent occurrence of underground safety accidents and serious disasters in recent years, the positioning of underground equipment is particularly important, which is also a prerequisite for automatic and safe production. In the mining process of coal resources, the shearer is one of the important equipment for underground ope...
