Embodiment Construction

[0015] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.

[0016] In order to better understand the technical solution of the present invention, the existing common winding methods are firstly explained:

[0017] When the optical fiber ring is wound, an optical fiber is divided into two equal sections A and B from the midpoint, and they are wound on two fiber supply wheels in advance (such as figure 1 shown), fix the midpoint of the optical fiber at the intersection of the axle and the rim of the bobbin. Such as figure 2 As shown, for the traditional quadrupole symmetrical winding method, fiber A winds the first layer of the fiber ring longitudinally along the wheel shaft, fiber B winds the second layer of the fiber ring longitudinally along the wheel shaft, and then ...

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.

Description

technical field [0001] The invention relates to the technical field of fiber optic gyroscopes, in particular to a winding method that can greatly improve the temperature characteristics of the fiber optic gyroscope, including the temperature shock resistance performance, and efficiently suppress the temperature error of the fiber optic gyroscope ring. Background technique [0002] As a new type of optical gyro instrument, the fiber optic gyroscope has an all-solid-state structure, high reliability, long life, wide accuracy coverage, fast start-up speed, short response time, large measurement range, wide dynamic range, shock and vibration resistance, small size, and weight Lightweight, low cost, all optoelectronic devices, suitable for mass production, etc., have been widely used in military and civilian fields. The fiber optic ring is the sensing core of the fiber optic gyroscope, and its winding quality directly determines the temperature characteristics of the fiber optic ...
