摘要
针对金属探测仪传感器设计时缺少理论分析的现状,文章基于开放式矩形平衡线圈模型,推导了金属杂质通过平衡线圈时产生的附加感应电动势,并进行仿真,得到了金属探测仪传感器平衡线圈的最佳尺寸比例以及金属杂质通过平衡线圈的最佳空间探测位置。通过实验验证了该计算方法的正确性,为进一步提高金属探测仪的检测灵敏度和稳定性提供了理论依据。
Based on the open rectangular balanced coil model to deal with the lack of theory analysis for the design of metal detector sensor,the additional induced electromotive force when metal impurities go through the balanced coil is inferred.The best size ratio of the sensor coil and the best spatial detection position when metallic materials go through the balanced coil are obtained by the simulation analysis.The correctness of the proposed method is confirmed by experiments,thus providing a theoretical basis for improving the detection precision and stability of metal detector.
