The invention belongs to the technical field of manufacturing of an optical fiber ring of an optical fiber gyro, and in particular relates to an optical fiber ring precision winding method. The methodcomprises the following steps: determining the length of optical fiber and the structure of the optical fiber ring; processing winding tooling; selecting suitable polarization maintaining optical fiber; winding single mode optical fiber; and winding the polarization maintaining optical fiber. The method needs to solve the problems that when a large-length optical fiber ring is wound, the existingoptical fiber winding method cannot guarantee the geometric symmetry of the optical fiber ring, the zero-drift amount of the optical fiber ring under the variable temperature condition is too large,and the precision of an inertial gyroscope is influenced. By customizing of the special-sized single-mode optical fiber and winding tooling, the gap between the optical fiber can be controlled when the polarization-maintaining optical fiber is wound, and the number of turns of the optical fiber in each layer is fixed. Based on a four-pole symmetrical winding method, the geometric symmetry of the optical fiber is finally ensured, the zero-drift amount of the optical fiber ring under the variable temperature condition is reduced, and the precision of the inertial gyroscope is improved.

The method is capable of accelerating positioning of single-phase ground fault points effectively and accurate in positioning.
