A precise positioning device and positioning method based on Hall positioning system

Abstract

The invention discloses a hall-positioning-system-based precise positioning apparatus and positioning method. The precise positioning apparatus is composed of a positioning system and a walking mechanism. A telescopic hall probe is selected to cooperate with the walking mechanism, so that precise millimeter-level positioning is realized; and a defect that the traditional geomagnetic positioning system only realizes geomagnetic reference point positioning can be overcome and precise positioning between adjacent geomagnetic reference points can be realized. The positioning system formed by the hall probe, a telescopic rod and a stepping motor is added and a positioning algorithm is realized based on an Arduino unit, so that precise positioning of any position between two geomagnetic reference points is realized without the need of improvement of the geomagnetic reference point density. Moreover, a precise turning effect with a 90-degree angle or an angle of a multiple of the 90 degrees is realized. The system structure is simple and positioning can be realized rapidly and precisely.
