Test method of automatic memory cutting coal self-positioning device for unmanned working face coal mining machine

Abstract

The invention discloses a test method for an automatic memorization and coal cutting self-positioning device of a manless working face coal mining machine and belongs to a method for testing a coal mining machine positioning device. By using the test method, a test experiment on the self-positioning device for automatic memorization and coal cutting of the manless working face coal mining machine is designed according to the self-positioning feature of the automatic memorization and coal cutting of the manless working face coal mining machine; the method comprises the following steps: firstly mounting an IMU (inertia measurement unit) inertia measurement component in the middle of a coal mining machine model, wherein the IMU inertia measurement component comprises three gyroscopes and three accelerometers of which the measurement directions are perpendicular, and a speedometer is arranged on a scraper conveyer in a simulation manner; then supplying research contents and steps of the test experiment, and designing two test lines of linear running and feeding running according to the change of a coal cutting line of the coal mining machine in site; finally analyzing the applicability, the reliability and the precision of the self-positioning device according to an acquired test data result. The test method disclosed by the invention has an important significance on improvement on the design of automatic control on the coal mining machine, improvement on the usability and the working reliability of equipment and prolonging of the service life.

Description

technical field [0001] The invention relates to a method for testing a positioning device of a coal mining machine, in particular to a method for testing a coal mining machine's self-memorizing coal-cutting self-positioning device in an unmanned working face of a coal mine. Background technique [0002] At present, there are many technologies and equipment that can be used for positioning and navigation, and the technologies are becoming more and more mature. Such as radio navigation, satellite positioning, astronomical navigation, geographic information-assisted navigation, inertial technology, dead reckoning (DR), geophysical parameter-assisted navigation, and a combination of two or more navigation systems, such as GPS / DR, GPS / MM, GPS / DR / MM and other combination methods. At this time, Kalman filter has become a standard algorithm for combined positioning information fusion, and a large number of improved algorithms have been derived to improve fusion accuracy, fault tole...
