Abstract

The present invention disclosed a multi -sensor coordinated measurement method and storage medium. Based on a integrated fusion magnetic sensor, including three magnetic induction units: Overhauser scales, magnetic field measurement units, magnetic flux measurement units, and TMRMeasurement unit; this method can solve the problem of compatibility between different types of magnetic sensors in the small space and work with the same phase.By using the same frequency feedback mechanism and wireless coil magnetic core structure, effectively improving the spatial electromagnetic information coupling caused by the stimulation process and induction process of the vector sensor and the scalar sensor, so that the magnetic sensors of different structures can work with each otherCooperate with the integration of work.This method can realize the miniaturization of the existing multi -type magnetic sensor measurement system and improve the comprehensive application accuracy of the system to meet the needs of weak magnetic detection methods and instruments in the fields of deep space and deep sea.

Description

technical field [0001] The invention relates to the field of sensor cooperative measurement, in particular to a mutual interference suppression method and storage medium for multi-sensor cooperative measurement. Background technique [0002] As one of the basic physical fields of the earth, the magnetic field can reflect the distribution of material components and geological structure information in the earth. Generally, the geomagnetic field is used as the limit, and the magnetic field below this range is a weak magnetic field. The development of weak magnetic measuring instruments not only has important research value in traditional fields such as geophysics and space magnetic surveying. According to the relatively mature magnetic measurement methods and working principles, various magnetic sensors have come out one after another. Among them, fluxgate measurement units, inductive magnetic sensors, and superconducting quantum interferometer sensors are widely used in the fi...
