Magnetic Sensor Positioning Method under Low Speed Movement Condition

为了提高磁传感器定位技术的实用性,将时分复用技术应用于磁传感器的定位中,有效解决了运动磁传感器的定位问题,提出了基于磁场模值的标量定位方法,解决了背景磁异常对磁传感器定位精度的影响,并理论分析和实验验证了所提方法的可行性,实验结果表明,定位距离在3 m内时误差在厘米级别,并有望随实验条件的改善而提高,且该方法定位的灵敏度非常高。

In order to improve the practicability of magnetic sensor, the time division multiplexing technology is applied in the localization of the magnetic sensor, which effectively solves the problem of the positioning of the moving magnetic sensor. A positioning method based on the magnetic field mode value is proposed, which solves the problem of the influence of the background magnetic anomaly on the positioning accuracy of the magnetic sensor. The .feasibility of the proposed method is verified by theoretical analysis and experiment. The experimental results show that the positioning error is in the centimeter level at 3 meters, and is expected to improve with the better experimental conditions. The method is very sensitive.
