Abstract

The invention discloses a mutual interference suppression method for multi-sensor cooperative measurement and a storage medium, which are realized based on an integrated fusion type magnetic sensor, and comprises three magnetic induction units: an Overhauser scalar magnetic field measurement unit, a fluxgate measurement unit and a TMR measurement unit. According to the method, the problem of mutual compatibility of synchronous and in-phase work of different types of magnetic sensors in a small space range can be solved. By using a same-frequency feedback mechanism and a coil-free magnetic core structure, space electromagnetic information coupling caused by an excitation process and an induction process of a vector sensor and a scalar sensor is effectively improved, so that magnetic sensors of different structures can be compatible to work, and the integration degree of mutual cooperative work of multiple types of magnetic sensors is effectively improved. According to the method, miniaturization of existing multi-class magnetic sensor measuring systems can be achieved, the comprehensive application precision of the system is improved, and the requirements of fields such as deep space and deep sea for weak magnetic detection methods and instruments are met.

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 inside the earth. Generally, the magnetic field is bounded by the geomagnetic field, and the magnetic field is weak if it is lower than this range. 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 more mature magnetic measurement methods and working principles, a variety of magnetic sensors have come out one after another. Among them, the most widely used in the field of weak magnetic measurement include fluxgate measurement units, inductive magnetic se...
