Abstract
Description
Technical Field
[0001] This utility model relates to the field of inertial measurement technology, specifically to a fiber optic gyroscope inertial measurement device. Background Technology
[0002] A fiber optic gyroscope is a completely solid-state inertial instrument with advantages not found in traditional electromechanical instruments. It is a closed-loop system composed solely of optical and electronic components, determining its angular velocity by detecting the phase difference between two beams of light. Therefore, structurally, it is a completely solid-state gyroscope with no moving parts. The advantages of its principle and structure give fiber optic gyroscopes significant advantages in many applications, especially in spacecraft where high reliability and lifespan are critical.
[0003] According to the patent application published on the Internet (authorization announcement number: CN 207379509U), "This utility model relates to a low-cost, miniaturized fiber optic gyroscope inertial measurement device, belonging to the field of inertial measurement technology. The three fiber optic gyroscopes of this utility model share a single light source, and the three fiber optic gyroscopes share a single signal processing and interface circuit, reducing the product's weight and power consumption; the targeted use of low-grade components reduces costs; as a fiber optic gyroscope inertial measurement device for aerospace applications, it is the first to use flexible wires instead of ordinary wires, improving product reliability and production efficiency; the use of a secondary integrated scheme for the light source-driven temperature control circuit reduces the size by more than 50% compared to traditional circuits."
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] In use, this utility model replaces the traditional analog circuit board with an integrated light source-driven temperature control module. It is small in size, fully electromagnetically shielded, and can be directly connected to the main body for heat conduction. The flexible wire connection helps reduce mutual interference between internal signal lines and enhances environmental adaptability. At the same time, it improves the efficiency and reliability of the assembly process. In actual use, because the three-axis integrated fiber optic gyroscope of this device has a fixed installation position, interference and incompatibility may easily occur during the fixed installation process when facing different installation environments. Therefore, it is necessary to improve the fiber optic gyroscope inertial measurement device to solve the above problems. Utility Model Content
