Title:
ACCURATE POSITIONING METHOD AND SYSTEM BASED ON MULTI-SOURCE INFORMATION FUSION AND FOR MONORAIL CRANE IN UNDERGROUND COAL MINE
Document Type and Number:
WIPO Patent Application WO/2023/173729
Kind Code:
A1
Abstract:
An accurate positioning method based on multi-source information fusion and for a monorail crane in an underground coal mine. The method comprises the following steps: calculating a dynamic location of a moving vehicle according to a vehicle-mounted label of a UWB system and a base station (S100); performing matrix transformation according to an attitude matrix contrast force which is output by a strapdown inertial navigation system, so as to calculate a traveling distance of the vehicle (S200); determining location information of a feature point according to a full-scene map constructed by a map construction system (S300); and constructing, according to a monorail crane traveling displacement model and accurate location information of the feature point, a Kalman filtering model for accurate positioning, and correcting a monorail crane real-time location model, so as to obtain accurate location information (S700). Further provided is an accurate positioning system based on multi-source information fusion and for a monorail crane in an underground coal mine. By means of performing information fusion on three positioning modes, the accuracy is guaranteed while a relatively high stability and anti-interference performance can also be achieved, and the system is applicable to the positioning of a monorail crane in an underground environment.
