Magnetic navigation method and its magnetic navigator

Abstract

The invention discloses a magnetic navigation method and a magnetic navigator used therein. The method comprises steps as follows: S1, a target magnet generates a space magnetic field, and a preset motion track is set in a space magnetic field range; S2, a plurality of fixed points are arranged on the preset motion track; S3, data of the magnetic navigator are initialized, and the magnetic navigator and the target magnet perform relative motion along the preset movement track; S4, the magnetic navigator collects incident magnetic flux at each fixed point in the movement track and outputs the incident magnetic flux at each fixed point in a form of voltage signals; S5, after the magnetic navigator completes movement along the movement track, the voltage signals are processed and converted into corresponding magnetic field intensity values, and the mode of the magnetic field intensity values of all fixed points is calculated; S6, the offset direction between the magnetic navigator and thetarget magnet is calculated according to symmetry of the data, and a result is output; S7, the position of the magnetic navigator is adjusted, and the steps S3 to S6 are repeated until the magnetic navigator is accurately positioned.

Description

technical field [0001] The invention relates to the technical field of magnetic navigation, in particular to a magnetic navigation method. Background technique [0002] The current so-called magnetic navigation or magnetic field navigation technology relies on the invariance of field lines or magnetic flux emitted by magnets in space and time. The Hall effect is one of the most widely used means. When the magnetic field line cuts through the electric field generated by the constant current power supply, a corresponding potential difference is induced in its positive direction. This potential difference is vectorial and directly related to the magnetic flux incident on the Hall sensor. [0003] A variety of applications can be derived from the aforementioned unique characteristics. It includes a magnetic switch. When the relative position of the magnet and the Hall sensor reaches a certain geometric condition, the Hall sensor judges according to the absolute value of the m...
