This invention relates to a high-precision data acquisition, processing, and magnetic field drive system, mainly comprising a data acquisition module, a processing module, a magnetic field drive module, a power supply module, and a host computer. The data acquisition module converts external analog signals into digital signals and transmits them to the processing module. The processing module includes a processing unit, a high-stability temperature-controlled crystal oscillator, an external clock signal interface, a DDR chip, Flash memory, a high-speed connector, and a digital power supply module. This module performs digital processing such as filtering and phase-locked loop (PLL) on the signals. The host computer can communicate with the FPGA core processing module via both Ethernet and serial ports to control the bias, amplitude, and frequency of the signals generated by the magnetic field drive module, display the read-back online data, and generate real-time curves. This invention realizes a low-cost, high-precision NMR gyroscope magnetic field control system, achieving high-precision closed-loop control of the NMR gyroscope's magnetic field.
