Coal mining machine explosion-prevention positioning apparatus based on strapdown inertial navigation, and calibration method thereof

Abstract

The present invention discloses a coal mining machine explosion-prevention positioning apparatus based on strapdown inertial navigation. The apparatus comprises an explosion-prevention box, a guide support device, a power supply module, a strapdown inertial navigation unit, a movable rubber vibration reducing mechanism device and a navigation data processing module, wherein the movable rubber vibration reducing mechanism device is fixedly arranged on the right side of the explosion-prevention box through fixation installation holes symmetrically arranged on the bottom portion of the explosion-prevention box, the strapdown inertial navigation unit is fixed on the movable rubber vibration reducing mechanism device, the power supply module is fixed on the guide support device, and the navigation data processing module is fixedly arranged on the left side of the explosion-prevention box through modules symmetrically arranged on the bottom portion of the explosion-prevention box. The invention further provides a calibration method. With the apparatus and the method, the defects of poor impact resistance, insufficient stability, insufficient reliability and the like can be effectively solved, and characteristics of high safety, strong environmental adaptability, good real-time property, good stability, simple operation, easy installation, and the like are provided.

Description

technical field [0001] The invention relates to an autonomous positioning device for a shearer, in particular to an explosion-proof positioning device for a shearer based on strapdown inertial navigation and a calibration method thereof, belonging to the technical field of absolute autonomous positioning of a shearer. Background technique [0002] Coal is an important basic energy and raw material in my country. The energy structure dominated by coal will not change for a long time. With the development of the national economy, the demand for coal is increasing, and the accompanying coal mine safety accidents are also constantly The technology of safe and efficient development and utilization of coal resources has become a hot research field for scholars at home and abroad. [0003] The fully mechanized mining face is the core area of ​​coal mine production, and as the core equipment of the "three machines" of the fully mechanized mining face, the shearer is responsible for t...
