Embodiment Construction

[0033] The technical solutions in the present invention are clearly and completely described below in combination with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] The allowable zero-bias variation △B of the optical fiber gyroscope is determined according to the customer's requirements for the zero-bias stability or zero-bias change index of the fiber optic gyroscope. More than 0.02° / h is taken as an example to illustrate the determination method of the start-up time of the fiber optic gyroscope.

[0035] A method for determining the starting time of a fiber optic gyroscope provided in this embodiment includes the following steps...

Abstract

The invention discloses a method and a system for judging the starting time of a fiber-optic gyroscope. The method and the system are used for judging the starting time or the starting process of thefiber-optic gyroscope by tracking and judging a zero offset change amplitude range in the working process of the fiber-optic gyroscope, and have the advantages of clear test steps, high operability and accurate and reliable judgment result in the whole judgment process.

Description

technical field [0001] The invention belongs to the technical field of optical fiber sensing, and in particular relates to a method and system for judging the starting time of an optical fiber gyroscope. Background technique [0002] The fiber optic gyroscope is an optical angular rate sensor based on the Sagnac effect. With the increasing requirements of modern weapons and inertial navigation on the fast response of the sensor, the fast start of the fiber optic gyroscope is particularly important. The startup time of the fiber optic gyroscope has become an item of the fiber optic gyroscope. important test parameters. [0003] In the current fiber optic gyroscope evaluation technology system, the definition and evaluation criteria of the fiber optic gyroscope startup time are no longer applicable to the accurate evaluation of the existing fiber optic gyroscope startup time. In the "Fiber Optic Gyroscope Test Method (GJB2426A-2015)", the start-up time is defined as the time ...
