Problems solved by technology

[0007] The above methods all realize the charging function of the nuclear magnetic resonance instrument launch system, but they all use the power supply to charge a single energy storage capacitor, and the next launch can only be carried out after the charge of the energy storage capacitor is completed. In the actual detection process, the launch The overall system takes a long time and the work efficiency is limited

Abstract

The invention relates to a fast charging and discharging power source device of a nuclear magnetic resonance water detector. The fast charging and discharging power source device is characterized in that a PC is connected with an MCU control module through a serial port, the MCU control module is connected with a DC-DC high-power module through a D / A converter, the DC-DC high-power module is connected with a 24V storage battery, generates high voltage and is connected with a switching circuit module through an anti-backlash protection circuit, the two output ends of the switching circuit module are connected with a first energy-storage capacitor and a second energy-storage capacitor respectively, a voltage collecting module collects the voltage value of the first energy-storage capacitor and the voltage value of the second energy-storage capacitor, and the output end of the voltage collecting module is connected with the MCU control module through an A / D converter. Compared with a prior method with a single capacitor included, the superposition time of every time is shortened, the working time of each pulse moment is shortened, the charging and discharging time is effectively shortened, and working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of geophysical exploration equipment for detecting water-containing bodies by using nuclear magnetic resonance, and in particular relates to a fast charging and discharging power supply device for a nuclear magnetic resonance water finding instrument. Background technique [0002] Compared with the drilling method, the MRS method has the advantages of low cost, non-destructive and high efficiency. Compared with other geophysical methods, MRS is a geophysical prospecting method for directly exploring groundwater. However, the measurement time for each test point generally takes more than one and a half hours. The impact of the test site on the environment, in areas with severe noise interference, electromagnetic noise interference is strong, and the number of superimpositions will increase accordingly, and the measurement time may be longer. This will reduce the efficiency of the MRS method and affect the promotion of ...
