摘要
主要研究了一种数字磁通门传感器。这种传感器采用单片机的A/D对磁通门输出信号进行采样。采样后的数据通过串口送给计算机进行运算,并得到最终的输出量。该传感器对地球磁场进行了测量。结果显示:它的误差较小,改善了传统磁通门传感器的温度性能,提高了输出信号的稳定性。
A digital fluxgate sensor is described. The output of the sensor is sampled by A/D of single chip processing. Then the signal is transmitted to single chip computer by serial ports ,and output value is obtained. The sensor measured earth magnetic filed strength. The results show the error is small and it can improved temperature property of fluxgate sensor and output stability.
