High-efficiency winding method for inhibiting temperature error of fiber gyro coil

Abstract

The invention relates to a high-efficiency winding method for inhibiting temperature error of fiber gyro coil. According to the invention, fiber is divided into a segment A and a segment B from a central point, the segment A and the segment B are respectively wound on two fiber supplying wheels, the middle point of the fiber is fixed on a connection part of the wheel shaft used for winding a frame and a wheel rim, the fiber A is vertically wound on a first layer of a fiber ring along the wheel shaft, the fiber B is vertically wound on a second layer of the fiber ring along the wheel shaft, then the fiber B is rewound to form a third layer, then the fiber A is rewound to form a fourth layer, according to an outer to inner mode, four layers alternatively wind the all fibers, and a quadrupolar symmetrical winding structure is completed. Based on symmetrical winding, a concept of the outer to inner symmetrical winding mode is introduced, the concept and a traditional symmetrical winding method are combined, and the outer to inner symmetrical winding mode is formed, the method can be used for any traditional symmetrical winding mode, the temperature characteristic of the fiber coil is greatly increased, such as the outer to inner quadrupolar winding mode, the outer to inner octupole-winding mode and the outer to inner hexadecapole winding mode.

AI Technical Summary

Problems solved by technology

The Shupe error is indistinguishable from the Sagnac effect of the fiber optic gyroscope's perception of the earth's speed, which will seriously reduce the actual detection accuracy of the fiber optic gyroscope

Especially when there is a large temperature impact in the application environment, even if the most optimized 16-pole symmetrical winding scheme is adopted, the residual temperature error in the fiber optic ring is still large, which seriously deteriorates the temperature performance of the high-precision fiber optic gyro
