AI Technical Summary

Technical Problem

Existing magnetic field testing methods are difficult to adapt to complex and ever-changing testing environments, resulting in insufficient accuracy and stability of magnetic field test results. Especially in underwater systems, when factors such as changes in the geomagnetic field, equipment leakage magnetic field, and induced magnetic field disturbances are superimposed, traditional methods are prone to problems of insufficient or excessive compensation.

Method used

An automatic magnetic interference compensation system for underwater system magnetic field testing environment is adopted, including an underwater multi-parameter measurement module, a spatiotemporal decoupling and separation module, and a hierarchical adaptive compensation module. Through multi-dimensional physical parameter measurement, spatiotemporal decoupling and separation, and hierarchical adaptive compensation, it identifies and separates geomagnetic disturbances, equipment leakage magnetic field and induced magnetic field disturbances, dynamically adjusts the compensation intensity, and outputs high-precision magnetic field measurement results.

Benefits of technology

It effectively reduces the superimposed effects of multiple magnetic interferences in complex testing environments, improves the accuracy and robustness of magnetic field testing, ensures the accuracy and stability of target magnetic field measurement, and significantly enhances the adaptability of magnetic field testing.
