金属探测器中自学习方法的研究

The research of self-study method in metal detector

金属探测器广泛应用于工、矿企业和生活。在做在线检测时,由被测物体而产生的"产品效应"影响金属探测器的检测效果。可根据检测中的采样信号的波形来对金属探测器的初始相位做调整,使系统达到更佳的检测效果。本文详细叙述了这种自学习方法的理论依据、实现方法和实验结果,证明了自学习方法的对检测效果有一定的改善。

Metal detector is used widely in industy and life. The ＂product impact＂ caused by detecting-object affect the purpose of detecting when the metal detector works. We can adjust the original phase of the metal detector depending on the waves of sampling signals so that the system achieve a better detecting effect. The theory bases and implementation of self-study method have been expatiated in this paper.
