Title:
WIDE MAGNETIC FIELD RANGE MEASURING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/090636
Kind Code:
A1
Abstract:
The invention discloses a wide magnetic field range measuring method and a device, which relate to the technology field of magnetic field measurement, and more particularly, to a measurement method for the magnetic field intensity of a medium-and-large range and an extremely large range. The method comprises: the measurement step for a medium-and-large magnetic field and the measurement step for an extremely large magnetic field. In addition to that, the method further comprises steps of: Step 1: placing four orthogonally-configured magnetic resistance resistors into an external magnetic field and obtaining the resistance value of each magnetic resistance resistor; Step 2: substituting the resistance values of two mutually orthogonal magnetic resistance resistors into the measurement step for a medium-and-large magnetic field for calculation; if calculation process converges, then, determining that the external magnetic field as a medium-and-large magnetic field with the calculation result representing the magnetic field intensity and the direction of the medium-and-large magnetic field; and if the calculation process does not converge, then substituting the resistance values of the four magnetic resistance resistors in the measurement step for an extremely large magnetic field for calculation and determining that the external magnetic field is an extremely large magnetic field with the calculation result representing the magnetic field intensity and direction of the extremely large magnetic field.
