Embodiment 1

[0013] Example 1, such as figure 1 As shown, this is a one-dimensional electromagnetic induction gyroscope. The gyroscope is composed of a coil 1, a magnetic guide shaft 2, and a magnetic detection panel 3. The coil 1 is wound around the outer circumference of the magnetic guide shaft 2, and the two ends of the magnetic guide shaft 2 are connected with magnetic The detection panel 3 and the induced electromotive force signal generated by the coil 1 are drawn out by the wire 4 .

Embodiment 2

[0014] Example 2, such as figure 2 As shown, this is a two-dimensional electromagnetic induction gyroscope. The gyroscope is composed of two sets of coils 1, the magnetic guide shaft 2, and the magnetic detection panel 3. The coil 1 is wound around the outer circumference of the magnetic guide shaft 2, and the two ends of the magnetic guide shaft 2 are connected. There are magnetic detection panels 3, and the adjacent magnetic detection panels 3 cannot be connected magnetically.

Abstract

The invention relates to an electromagnetic induction gyroscope, comprising a coil, a magnetic guide shaft, a magnetic detection panel; wherein, the coil winds on the magnetic guide shaft; the magnetic guide shaft is connected with the magnetic detection panel; when the gyroscope moves in a geomagnetic field or other external magnetic fields, magnetic flux of the coil changes, so that induced electromotive force is generated at the two ends of the coil. The induced electromotive force and the coil axial directon in the gyroscope are related to the included angle and the rotation speed of the field direction. The gyroscope based on electromagnetic induction is a passive whirly monitoring sensor, the gyroscope has the characteristics of simple and stable structure, small volume, good impact resistance capacity, stable temperature property and convenient application, thus being widely applied to the angular velocity measurement and magnetic density measurement of whirling objects.

Description

technical field [0001] The invention relates to a gyroscope based on electromagnetic induction. The present invention has special applications in the angular velocity monitoring of space vehicles and rotating objects, such as the navigation of aircraft and missiles, but can also be widely used in the angular velocity measurement of other rotating objects, such as the movement and rotation control of manipulators, and the measurement of magnetic field strength. Background technique [0002] Gyroscope is a kind of rotation monitoring sensor, which has a wide range of applications in engineering technology and scientific research, such as aircraft navigation, manipulator movement and rotation control, etc. At present, the commonly used gyroscopes include mechanical gyroscopes, piezoelectric crystal gyroscopes, laser gyroscopes and fiber optic gyroscopes. Mechanical gyroscopes have high precision and good stability, but poor impact resistance and large volume and weight. Piezo...
