Embodiment Construction
[0037] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0038] see Figure 1A , the aircraft M, an inertial measurement unit (not shown) is set on the aircraft M, the inertial measurement unit includes an accelerometer and a gyroscope, the accelerometer detects the acceleration signal of the object in the independent three-axis of the carrier coordinate system, and the gyroscope detects that the carrier is relative to the navigation The angular velocity signal of the coordinate system measures the angular velocity and acceleration of the object in three-dimensional space, and calculates the attitude of the object based on this solution. ...

The invention provides an aircraft calibration device which is used for assisting in calibrating an aircraft. The device comprises a base assembly, a rotating assembly and a clamping assembly, whereinthe base assembly is used for providing support for the aircraft so that the aircraft can be away from a supporting face, the clamping assembly comprises a supporting disc assembly and a clamping piece, the supporting disc assembly is connected with the rotating assembly, the clamping piece is arranged on one side, away from the rotating assembly, of the supporting disc assembly and used for clamping the aircraft, the supporting disc assembly comprises a fixed disc, a rotary disc and a rotary shaft, the fixed disc is fixed on a rotary connecting rod, the rotary shaft is connected with the rotary disc and the fixed disc so that the rotary disc can rotate relative to the fixed disc, the rotary disc is provided with a through hole and a positioning pin, and the positioning pin can move relative to the through hole under the action of external force so as to apply the force to the fixed disc or be away from the fixed disc, so the rotary disc and the fixed disc are switched between a relatively fixed state and a relatively rotatable state.
Description
【Technical field】 [0001] The invention relates to the technical field of calibration equipment, in particular to an aircraft calibration equipment. 【Background technique】 [0002] In order to accurately control the flight attitude of drones and other aircraft, it is necessary to adjust the relevant parameters of the aircraft inertial measurement unit, that is, to perform geomagnetic calibration and obtain geomagnetic curves. During the calibration process, the aircraft needs to be rotated, and there should be no large angle difference during the rotation process, so as to fit the data curve to obtain the calibration geomagnetic curve and other parameters. [0003] In the prior art, the geomagnetic calibration is usually done by manually rotating the aircraft, which has poor calibration accuracy and is not suitable for mass production operations. 【Content of invention】 [0004] In order to overcome the shortcomings of the prior art, the invention provides an aircraft calib...
