Program-controlled impact device for automatically measuring output delay time of fiber-optic gyroscope

Abstract

The invention discloses a program-controlled impact device for automatically measuring the output delay time of a fiber-optic gyroscope. A motor is installed on the lower side of a base of the program-controlled impact device; a push rod, a torsional spring and an oscillating arm striker are installed on a motor shaft from the lower part to the upper part in sequence, so that the push rod can rotate with the motor shaft, and the oscillating arm striker can rotate around the motor shaft; an angle sensor is installed at the other end of the motor shaft; a limiting spring leaf is installed on the base through the torsional spring, so that the limiting spring leaf is closely attached to the tail end of the oscillating arm striker under the effect of the torsional spring; and a control unit is connected with the angle sensor and the motor respectively and controls the motor to rotate and to drive the push rod to rotate by monitoring a rotate angle in real time, and the striker is pushed further to be reset and to trigger the limiting spring leaf to release the striker. The program-controlled impact device adopts a feedback control technology, is accurate in control and stable to operate, does not need high current starting, and is free of electromagnetic interference. By adopting the device, the fully automatic measurement of the output delay time of the fiber-optic gyroscope can be realized.

Description

technical field [0001] The invention relates to a program-controlled impact device, in particular to an automatic impact device for measuring output delay time of an optical fiber gyroscope based on instantaneous impact. Background technique [0002] The output delay time of the fiber optic gyroscope is the part of the delay time of the fiber optic gyroscope signal output relative to the signal input that has nothing to do with the input frequency, and is an index that reflects the dynamic performance of the fiber optic gyroscope. The output delay time of the FOG reflects the tracking accuracy of the FOG to the angular velocity input. The shorter the output delay time, the faster the fiber optic gyroscope responds to the angular velocity input. [0003] Fiber optic gyroscopes are widely used in the field of national defense and military affairs. Modern aviation weapons have high flight speeds and rapid changes in flight trajectories. Under high dynamic environmental conditi...
