The invention relates to a double-coil structure for nuclear magnetic resonance gyroscope high-precision magnetic field control. According to the structure, a framework is used for fixing a close-wound solenoid coil and a Helmholtz coil. The static magnetic field is generated by the close-wound solenoid coil and Helmholtz coil together. The complete structure is arranged in a multilayer magnetic shielding cylinder, and the multilayer magnetic shielding cylinder can shield part of the magnetic field. The close-wound solenoid coil is used for generating a stable intense magnetic field, which has higher magnetic field uniformity and is suitable for roughly regulating the static magnetic field. The Helmholtz coil is used for compensating the remanent field in the magnetic shielding cylinder, and the generated magnetic field has lower intensity, poor uniformity and higher regulation precision. The two coils are matched, thereby reducing the device volume, and solving the problem of insufficient control precision in the numerical control electronic system. By adopting the double-coil structure, the control precision can be enhanced by 75 times.
