| description | The invention relates to the field of magnetic variable measurement, in particular to a fluxgate anti-interference method and device based on waveform feature classification, and the method comprises the steps: outputting an excitation signal excitation probe of a required frequency; acquiring an induction signal of the probe by referring to the phase of the excitation signal, and performing digital signal processing on the induction signal in the sampling window to obtain the current magnetic induction intensity; an induction signal is received, the signal form is identified, an abnormal phase is marked, and then an abnormal signal is cut off; carrying out magnetic field data calculation on the induction signal without the abnormal signal to obtain a current magnetic induction intensity measurement value; and processing the current magnetic induction intensity measurement value and then outputting the data. According to the invention, based on the analysis of the physical characteristics of the fluxgate prob |
