基于磁通门与加速度传感器的三分量磁力仪研究

摘要

Magnetometer is widely used in national production. The three-component magnetometer based on fluxgate and ac-celerometer is proposed by comparing the traditional three-component magnetometer. The hardware circuit structure of the magne-tometer is simply introduced. The types of magnetometer measurement error are emphatically analyzed to choos the appropriate optimization algorithm for error calibration. The Nelder-Mead simplex algorithm is used to calibrate the non-coaxial error. The re-sults of measurement and calibration are given and analyzed.%磁力仪在国民生产中有着广泛的用途，在比较了传统的三分量磁力仪之后，提出一种基于磁通门与加速度传感器的三分量磁力仪。首先，简单地介绍了该磁力仪的硬件电路组成结构，之后，为了选用适当的优化算法对测量误差进行校正而重点讨论了该磁力仪的测量误差种类，后采用Nelder-Mead单纯形算法对于该磁力仪的不共轴误差进行校正。最后，做了测量及校正实验，并进行了实验结果分析。
