Description

Technical Field

[0001] This invention relates to the field of fiber optic gyroscope manufacturing technology, and in particular to a method for quadrupole symmetrical winding of a dual-channel fiber optic ring. Background Technology

[0002] Currently, fiber optic gyroscopes are instruments capable of accurately determining the orientation of moving objects. They are widely used inertial navigation instruments in modern aviation, navigation, aerospace, and defense industries. The fiber optic loop is the core component of a fiber optic gyroscope, and its winding requires neat fiber arrangement, uniform tension, and high symmetry.

[0003] Currently, the domestic method for winding fiber optic rings is a single-channel four-pole symmetrical winding method. This method produces products with only one channel and cannot meet the special technical requirements of customers for dual-interface fiber optic gyroscopes. Summary of the Invention

[0004] This invention provides a method for quadrupole symmetrical winding of a dual-channel fiber optic ring to solve the problem that existing winding methods can only produce a single channel and cannot wind dual interfaces, thus failing to meet customers' requirements for dual-interface fiber optic gyroscopes.

[0005] To achieve the above objectives, the present invention provides a method for quadrupole symmetrical winding of a dual-channel optical fiber ring, characterized by comprising the following steps:

[0006] S10: First, identify the optical fibers to be wound and label them as fiber A1, fiber B1, fiber A2 and fiber B2 respectively.

[0007] S20: Connect optical fibers A1, B1, A2, and B2 to the quadrupole winding machine;

[0008] S30: The first layer is wound with fiber A1 by arranging the fibers from left to right;

[0009] S40: The second layer is wound with fiber A2 by arranging the fibers from left to right;

[0010] S50: The fiber B1 is wound by arranging the fibers from left to right in the third layer.

[0011] S60: The fiber B2 is wound by arranging the fibers from left to right in the fourth layer.

[0012] S70: The fiber B1 is wound by arranging the fibers from right to left in the 5th layer.

[0013] S80: The fiber B2 is wound by arranging the fibers from right to left in the 6th layer.

[0014] S90: The fiber A1 is wound by arranging the fibers from right to left in the 7th layer;

[0015] S100: The fiber A2 is wound by arranging the fibers from right to left on the 8th layer.

[0016] S110: The above 8 layers of winding is a cycle (i.e., steps S30-S100), and the winding is repeated until the required number of layers is reached, thus completing the winding of the entire product.

[0017] The beneficial effects of this invention are:

[0018] First, this invention can wind a dual-channel fiber optic ring product. This product is made of two sets of optical fibers that can work independently. Therefore, this product has two interfaces and can meet the multi-channel needs of customers.

[0019] Secondly, this invention achieves four-pole symmetrical winding of two sets of optical fibers, resulting in good symmetry and consistency. Due to the consistent and symmetrical parameters, gaps are mutually compensated during winding, forming a layered safety isolation, making the distribution uniform, compact, and reasonable. The two sets of optical fibers have completely identical performance. Because it is a dual-channel layout, when one set of optical fibers is damaged, it will not affect the operation of the other set of optical fibers, while giving it good working performance and stability.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example: A method for quadrupole symmetrical winding of a dual-channel fiber optic ring, comprising the following steps:

[0023] S10: First, identify the optical fibers to be wound and label them as fiber A1, fiber B1, fiber A2 and fiber B2 respectively.

[0024] S20: Connect optical fibers A1, B1, A2, and B2 to the quadrupole winding machine;

[0025] S30: The first layer is wound with fiber A1 by arranging the fibers from left to right;

[0026] S40: The second layer is wound with fiber A2 by arranging the fibers from left to right;

[0027] S50: The fiber B1 is wound by arranging the fibers from left to right in the third layer.

[0028] S60: The fiber B2 is wound by arranging the fibers from left to right in the fourth layer.

[0029] S70: The fiber B1 is wound by arranging the fibers from right to left in the 5th layer.

[0030] S80: The fiber B2 is wound by arranging the fibers from right to left in the 6th layer.

[0031] S90: The fiber A1 is wound by arranging the fibers from right to left in the 7th layer;

[0032] S100: The fiber A2 is wound by arranging the fibers from right to left on the 8th layer.

[0033] S110: The above 8 layers of winding is a cycle (steps S30-S100), and the winding is repeated (i.e., steps S30-S100; S30-S100...S30-S100; S30-S100) until the required number of layers is reached, and the winding of the entire product is completed.

[0034] Specifically, the aforementioned four-pole winding machine can be directly purchased from Wuhan Optics Valley Changyingtong Measurement Co., Ltd., and since it is existing technology, it will not be described in detail.

[0035] Among them, fiber A1 and fiber B1 are the first channel; while fiber A2 and fiber B2 are the second channel.

[0036] During the winding process, the first eight layers are wound in a cyclical sequence: A1-A2-B1-B2-B1-B2-A1-A2. The winding sequence for the first channel is A1-B1-B1-A1, and for the second channel it is A2-B2-B2-A2. Therefore, both satisfy the ABBA four-pole symmetrical winding process. This invention has the following characteristics, which are analyzed below:

[0037] First, this invention can wind a dual-channel fiber optic ring product. This product is made of two sets of optical fibers that can work independently. Therefore, this product has two interfaces and can meet the multi-channel needs of customers.

[0038] Secondly, this invention achieves four-pole symmetrical winding of two sets of optical fibers, resulting in good symmetry and consistency. Due to the consistent and symmetrical parameters, gaps are mutually compensated during winding, forming a layered safety isolation, making the distribution uniform, compact, and reasonable. The two sets of optical fibers have completely identical performance. Because it is a dual-channel layout, when one set of optical fibers is damaged, it will not affect the operation of the other set of optical fibers, while giving it good working performance and stability.

It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
