Device and method for detecting resonance frequency of meridians

The invention discloses a device and a method for detecting the resonance frequency of meridians, and belongs to the technical field of information collection. The device comprises: a lock-in amplifier for outputting a sinusoidal alternating-current signal and receiving a test signal with a preset frequency; a constant-current source used for converting the sinusoidal alternating-current signal into an excitation signal of a constant alternating-frequency current and transmitting the excitation signal to an electrode connector; the electrode connector used for receiving the excitation signal transmitted by the constant current source, connecting a target meridian, scanning the target meridian by using the excitation signal with a preset frequency, and acquiring a test signal with the preset frequency received by the lock-in amplifier; and a main controller used for acquiring test data of the electrode connector, determining the minimum impedance frequency point of the current transmitted by the target meridia
