A metal target detection system based on improved balance coil is proposed to identify the moving state of metal targets.The technology of electromagnetic induction metal detection is analyzed,the characteristics and working principle of the balance coil structure are compared,and the motion state information of the metal object is judged by the change of the differential signal output by the balance coil.The experimental test shows that the balanced electromagnetic induction metal detection has the characteristics of good noise suppression and high sensitivity.It can detect metal objects reliably in a certain environment,and effectively monitor the movement state and speed of metal objects through the upper function.
