ActiveCN106908847AGreat signal strengthControl flight altitudeDetection using electron/nuclear magnetic resonanceEngineeringTransmitter
The invention provides a ground-and-air nuclear magnetic resonance underground water detecting system and a ground-and-air nuclear magnetic resonance underground water detecting method. The system comprises two grounding electrodes which are connected with a transmitter through transmitting lead. The transmitter is controlled through a ground master control system. The transmitter transmits excitation current with frequency of local Larmor frequency to ground through changing emission current of the grounding electrodes. A receiving coil which is loaded on an aerial vehicle acquires a nuclear magnetic resonance signal which is generated by magnetic moment precession. The ground master control system performs remote controlling on transmission and stoppage of the excitation current through a communication module. The ground master control system makes a receiver which is connected with the receiving coil acquire the nuclear magnetic resonance signal in a gap when the excitation current is stopped through the communication module. The acquired nuclear magnetic resonance signal is transmitted to an upper computer through the communication module. The ground-and-air nuclear magnetic resonance underground water detecting system and the ground-and-air nuclear magnetic resonance underground water detecting method has advantages of large ground transmitting and detecting depth, high resolution, wide air receiving and detecting range, high detecting speed and effective underground water resource detecting range.
