Abstract:
    The invention is a supporting part used for coin identifiers, specially a multivector analysis coil-identifying module, comprising the four parts of signal generating circuit, signal conditioning circuit, signal measuring circuit and coin identifying circuit, where the signal generating circuit generates a sine-wave signal whose vibrating frequency, amplitude and output impendence change with the deposited coins; the signal conditioning circuit reshapes the sine-wave signal into square-wave gate control signal and transmits it to the signal measuring circuit; the signal measuring circuit measures the square-wave gate control signal, including signal frequency, amplitude and gate control signal time, and inputs the measured data into the coil identifying circuit; the coin identifying circuit identifies the input data and then outputs coin kind and true/false information. And the invention can fast and accurately identify coins, retrieving economic losses for nation and enterprises.
