Unmanned aerial vehicle gravity center measurement and calibration device

Abstract

The invention provides an unmanned aerial vehicle gravity center measurement and calibration device, and belongs to the field of research of unmanned aerial vehicle accessory equipment. According to the design, automatic balance and automatic calibration are adopted, and the gravity center of the unmanned aerial vehicle can be rapidly measured and calibrated, so determination of an installation position of subsequent electronic equipment is facilitated; a polar coordinate scheme is adopted, double balance beams and an electromagnetic magnet are balanced, a process is rapid and agile, and the balance fluctuation is small; for a balanced vehicle body, a laser head or a calibration pen are adopted to calibrate the gravity center, and an observation effect is simple and clear; the device is convenient to use and can measure the gravity center of the unmanned aerial vehicle of any size.

Description

technical field [0001] The invention provides a center-of-gravity measurement and calibration device of an unmanned aerial vehicle, which belongs to the field of object gravity center measurement and calibration, in particular to the field of the center-of-gravity measurement and calibration device installation of an unmanned aerial vehicle. Background technique [0002] In the field of drone research, the measurement of the center of gravity has always been a difficult problem in the industry. Because of the installation of accessories such as subsequent electronic equipment, the center of gravity of the drone is often difficult to determine. During the installation process, constant debugging is required to ensure that the center of gravity appears where it needs to be, so as to meet the stability during flight. [0003] According to the traditional method of measuring the center of gravity of irregular objects, most of them use the vertical line method to measure the pos...

Problems solved by technology

[0003] According to the traditional method of measuring the center of gravity of irregular objects, most of them use the vertical line method to measure the position of the center of gravity of the drone. Although this method is effective, it is difficult to implement because of the irregular surface of the fuselage. To calibrate the position of the center of gravity, two measurements are required

The most important thing is the hysteresis, that is, it can be measured after the equipment is installed, and it cannot be measured in real time, and then feedback to adjust the installation position of the electronic equipment, which is very inconvenient to use
