Abstract

The invention discloses a coal cutter autonomous navigation system and method. The system comprises a total station, a UWB fixed base station group, a UWB mobile base station group, a UWB positioningnode, a north seeker and a tilt angle sensor, wherein the total station is adopted as the system standard to be installed at the conveying uphill and zone haulage way intersection point. The UWB fixedbase station group is installed at a reversed loader at the fully mechanized coal mining face and the haulage way intersection point and adopted as the coordinate reference of the coal face. The UWBmobile base station group is installed below a roof of a hydraulic support, and is autonomously calibrated along with the hydraulic support. The UWB node, the north seeker and the tilt angle sensor are installed on a coal cutter body. When the coal cutter works, the UWB mobile base station positions the UWB node and transmits the UWB node to the UWB fixed base station group. The UWB fixed base station group is calibrated by the total station. The coal cutter is positioned at a reference coordinate system through a coordinate transformation matrix, the north seeker and the tilt angle sensor areused for performing absolute measurement on the posture of the coal cutter body, and therefore full-autonomous navigation of the coal cutter in complete coal seam coal mining can be completed.

Description

technical field [0001] The invention relates to a coal mining machine in a fully mechanized mining face, in particular to an autonomous navigation system and method for the coal mining machine. Background technique [0002] Shearer is one of the main equipment of fully mechanized mining equipment. In the traditional coal seam mining process. The travel route of the coal shearer is drawn by the measurement department, and the coal mining staff control the state of the hydraulic support group and the scraper conveyor, and then control the collection route of the coal shearer. At present, the navigation method of the shearer is mainly manual direct-view remote control. Due to the harsh environment of mine roadways, this navigation method is not only inefficient, but also has limited accuracy. In addition, the coal mining face is a mine accident-prone area, which greatly increases the work intensity and risk of coal mining workers. [0003] With the progress of society, the ...
