Problems solved by technology

[0012] The positioning accuracy of the existing fiber optic gyro north finder mainly depends on the accuracy of the angle sensor, and the high-precision angle sensor is expensive, which is not conducive to reducing costs
The locking of the existing fiber optic gyro north finder mainly adopts the pin-hole cooperation method. In the vibration environment, it is prone to lock-up and the reliability is not high.

Abstract

The invention discloses a locking and locating mechanism for a fiber-optic gyroscope north seeker. The locking and locating mechanism for the fiber-optic gyroscope north seeker is mainly formed by a locating plate and a locking component. The functions of locking, unlocking, locating and the like of rotating components of the fiber-optic gyroscope north seeker are realized through the control of a direct-current motor and the detection of a photoelectric sensor signal by matching with the locating plate, and thus the north seeking function of the fiber-optic gyroscope north seeker is realized. According to locking and locating mechanism for the fiber-optic gyroscope north seeker, disclosed by the invention, the size is small, the reliability is high, the accurate location requirement needed by the fiber-optic gyroscope north seeker is met, and the stability and the reliability of the rotating components of the fiber-optic gyroscope north seeker are increased.

Description

technical field [0001] The invention belongs to the technical field of inertia, and in particular relates to a locking and positioning mechanism for an optical fiber gyro north finder. Background technique [0002] The geographic north at a point on the earth is the north tangent direction of the meridian at that point, that is, the tangent direction on the horizontal plane pointing to the North Pole at that point on the earth. The north angle of a certain direction at a certain point on the earth's surface or in the earth or above the earth refers to the angle between the projection of the direction on the horizontal plane at that point and the geographic north. The process of determining the north angle by some method is called north finding. [0003] The north finder is generally designed with the principles of magnetic north finding (electronic compass), gyro north finding, accelerometer north finding, radio north finding, etc. The fiber optic gyroscope is a new generat...
