Automatic resonance matching device for nuclear magnetic resonance water detector

The invention relates to an automatic resonance matching device for a nuclear magnetic resonance water detector. A 24V storage battery (1) is connected with an inductive load through an embedded micro LCR measuring instrument, a relay and a driving circuit of the relay, a PC is respectively connected with the embedded micro LCR measuring instrument, the relay and the driving circuit of the relay through an MCU control circuit, and the MCU control circuit is connected with a resonance matching capacitor set through a high-voltage relay and a driving circuit of the high-voltage relay and a driving circuit thereof. The micro LCR measuring instrument is embedded into the nuclear magnetic resonance water detector, it is unnecessary to carry a commercialized LCR measuring instrument, cost is reduced, and the measuring process is simplified. As the embedded micro LCR measuring instrument and the nuclear magnetic resonance water detector share one storage battery, when the nuclear magnetic resonance water detector is used in the open, it is unnecessary to arrange a special inverter to supply power to the LCR measuring instrument. The whole resonance matching process is automatically completed, personnel participating is not needed, use is convenient, the use difficulty of the nuclear magnetic resonance water detector is reduced, and particularly, non-specialized personnel only need to master a few operation methods to use the automatic resonance matching device.
