Abstract

Embodiments of the present application provide a low-frequency magnetic field measurement method, device, electronic device, and storage medium. The method includes: applying a preset digital weighting processing method, and performing weighting processing on a time-domain signal of a target low-frequency magnetic field based on a target standard limit value , to obtain the corresponding digital time-domain waveform signal, in which the digital weighting processing method corresponds to the standard limits of multiple standards, and the target standard limit is one of the standard limits of multiple standards; for digital time-domain waveform signals Perform digital detection processing to obtain the corresponding digital detection voltage; calibrate the sampling result of the digital detection voltage to obtain the magnetic field amplitude of the target low-frequency magnetic field and / or the percentage of the magnetic field amplitude relative to the target standard limit. The present application can be applied to the weighted measurement of the standard limits of various standard versions, thereby effectively improving the applicability of the low-frequency magnetic field measurement, and ensuring the accuracy and reliability of the low-frequency magnetic field measurement.

Description

technical field [0001] The present application relates to the technical field of magnetic field measurement, and in particular to a low-frequency magnetic field measurement method, device, electronic device, and storage medium. Background technique [0002] The low frequency magnetic field refers to the magnetic field in the frequency range of 1Hz-100kHz. The low-frequency magnetic field measurement usually uses a magnetic field coil antenna as a sensor. The magnetic field coil antenna receives the space magnetic field and converts it into a voltage signal. For subsequent measurements, according to the measurement requirements, there are time domain measurement methods and frequency domain measurement methods. The time domain measurement method obtains the magnitude of the magnetic field or the percentage of the magnetic field amplitude relative to standard limits, while the frequency domain measurement method obtains the spectrum of the measured signal. For time domain mea...
