More Information
Summary:The invention relates to a metal detector. The metal detector comprises a coil oscillating circuit, a pulse conversion circuit, a main control circuit, a display circuit, a power supply circuit and analarm circuit, wherein the coil oscillating circuit, the pulse conversion circuit and the main control circuit are connected in sequence; and the main control circuit is also connected with the display circuit, the power supply circuit and the alarm circuit. According to the metal detector, the coil oscillating circuit is used for generating a reference oscillating signal and a real-time oscillating signal, so that the main control circuit generates a reference signal and a real-time signal; by comparing the waveforms of the reference signal and the real-time signal, whether metal approachesor not can be judged, so that the aim of metal detection is fulfilled; and moreover, the metal detection is judged by judging whether the metal approaches or not according to the change of the waveforms instead of directly usi
