Construction and application of fiber optic gyro digital prototype based on digital twin technology

As a new generation of optical inertial navigation products, fiber optic gyroscopes (FOGs) have become a new trend in modern international inertial autonomous navigation equipment due to their technical advantages of high precision, full solid-state, and high reliability. In recent years, with the rapid development of China's fiber optic gyro industry, the application fields of FOGs have begun to actively expand from traditional areas to emerging fields such as smart oceans, smart cities, and intelligent navigation. In this process, traditional design and manufacturing methods cannot meet the new demands of emerging fields for FOG industries, which include high precision, miniaturization, flexible design, batch manufacturing, intelligent networking, diversified interfaces, full lifecycle services, and low-cost commercialization. This paper attempts to explore a new system for the design, manufacturing, and full lifecycle management of fiber optic gyros based on digital twin technology. It aims to closely integrate digital twin technology with key links, scenarios, and objects in the fiber optic gyro to enhance the level of intelligence and the efficiency and reliability of design, production, and verification. It is hoped that this work can provide a reference for the further development and application of digital twins in high-tech product industries, taking fiber optic gyros as an example.
