Aiming at the demand of low frequency alternating magnetic field signal extraction function in the background of marine environment, a set of low frequency alternating magnetic field signal processing and storage module is designed based on embedded MCU. The module uses a FatFs file system and a micro SD card with spectrum analysis and line spectrum extraction. Finally, the function of the module was verified by data simulation and Helmholtz coil test.
