摘要

为了提高磁通门的动态测量范围、测量精度及其工作稳定性,提出了一种以DSP数字信号处理器为主的磁通门信号处理方法。根据双铁芯磁通门的基本原理,对磁通门感应信号进行模数转换、数字波形“门”处理和数字带通滤波等数字信号处理。仿真结果表明,此种磁通门数字信号处理方法可有效减少磁通门噪声,提高磁通门灵敏度和测量精度,为数字磁通门磁强计的应用研究提供了参考。

Abstract

In order to expand the dynamic measuring range of flux gate and improve the measurement accuracy and the work stability of flux gate, a flux gate signal processing method based on DSP digital signal processor was proposed. According to the basic principle of double iron core flux door, the analog to digital conversion of flux gate induction signal, digital waveform "gate" processing and digital bandpass filtering and other digital signal processing were carried out. The simulation results show that the flux gate signal processing method can effectively reduce the flux gate noise, improve the flux gate sensitivity and measurement accuracy, and also provide a reference for the application of digital flux gate magnetometer.

Key words： flux gate; digital signal processing; digital signal waveform "gate" processing; digital bandpass filtering
