Summary:The invention, which belongs to the technical field of electrical or magnetic prospecting and detection technologies, provides a time-sharing multi-frequency metal detection machine with the advantages of comprehensive detection, high detection sensitivity, and good stability. The time-sharing multi-frequency metal detection machine is composed of a control unit, a signal generation unit, a power amplification unit, a transmitting coil, a balancing receiving coil, a reception unit, a signal conditioning unit, a zero point control unit, a demodulation unit, a vector signal processing unit, and a data sampling unit. The structural key point of the detection machine is characterized in that the control unit, the signal generation unit, the power amplification unit, and the transmitting coil are successively connected; the balancing receiving coil, the reception unit, the signal conditioning unit, the zero point control unit, the demodulation unit, the vector signal processing unit, the data sampling unit, and th
