Abstract

The invention relates to the technical field of inertial navigation, and in particular relates to a small-size fiber-optic gyroscope signal processing circuit based on integrated packaging. The circuit comprises a signal acquisition unit, an output driving unit and an RS-422/485 communication interface unit; all the units use bare chips, all the units work independently and do not interfere with one another, the signal acquisition unit, the output driving unit and the RS-422/485 communication interface unit are packaged in the same cavity, and integrated packaging is achieved. According to theinvention, a plurality of components are integrated by adopting integrated packaging and single-cavity multi-layer wiring, and all functional units are packaged and integrated in the same cavity; compared with the existing discrete device structure, the circuit has the advantages that the integration level of a fiber-optic gyroscope system is improved, and the circuit packaging size is greatly reduced while multiple functions required by a fiber-optic gyroscope system are integrated; and the military quality grade requirement of the H-grade standard in GJB2438A-2002 General Specification forHybrid Integrated Circuits can be met.

Description

technical field [0001] The invention relates to the technical field of inertial navigation, in particular to a small-sized fiber optic gyroscope signal processing circuit based on integrated packaging. Background technique [0002] Fiber optic gyroscope is an important part of inertial navigation system, mainly composed of two parts: optical circuit and signal processing circuit. In the traditional design, the purpose of the signal processing circuit is to convert the voltage signal of the fiber optic gyroscope into a frequency signal. Signal processing circuits are usually designed with separate plastic or pottery components. This design is often low in efficiency, high in cost, and takes up a lot of space. It is easy to cause signal crosstalk and loss, which hinders the miniaturization of fiber optic gyroscopes, thus limiting the optical fiber. The field of application of the gyroscope. Contents of the invention [0003] In order to solve the above-mentioned problems o...
