Automatic balancing system for unmanned aerial vehicle

Abstract

The invention provides an automatic balancing system for an unmanned aerial vehicle. The automatic balancing system comprises a sensor, balancing liquid, liquid conveying pumps and containers for storing the balancing liquid, wherein the sensor is used for acquiring gravity center change data of the unmanned aerial vehicle, and the liquid conveying pumps are used for adjusting the weight of the balancing liquid in the containers according to the gravity center change data so as to keep the center of gravity of the unmanned aerial vehicle in a safe range. According to the automatic balancing system for the unmanned aerial vehicle, provided by the invention, for a load of fixed weight, the center of gravity of the unmanned aerial vehicle can be kept in the safe range through liquid conveying pump adjustment without using counterweights, so that the maneuverability and stability of the unmanned aerial vehicle are guaranteed; for a load of variable weight, the center of gravity of the unmanned aerial vehicle can be dynamically kept in the safe range through continuous adjusting by the liquid conveying pumps so as to guarantee the maneuverability and stability of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an automatic trim system for unmanned aerial vehicles. Background technique [0002] UAV (unmanned aerial vehicle or drone) is an unmanned aerial vehicle operated by radio remote control equipment or its own program control device. It first appeared in the 1920s, when it was used as a target drone for training. [0003] UAVs have a wide range of uses, low cost, good cost-effectiveness ratio; no risk of casualties; strong survivability, good maneuverability, and easy to use. They play an extremely important role in modern warfare and have broad prospects in the civilian field. [0004] During the use of drones, it is usually necessary to mount different loads, such as border patrol, nuclear radiation detection, aerial photography, aerial prospecting, disaster monitoring, traffic patrol, public security monitoring, etc., and monitoring equipment, such as pesticide spraying,...

AI Technical Summary

Problems solved by technology

[0007] If a container for storing liquid medicine is mounted on one load platform, the weight of the container for storing liquid medicine will change as the liquid sprays, and monitoring equipment is mounted on another load platform. At this time, it is difficult to ensure that no one will The center of gravity of the drone is within a safe range, which affects the maneuverability and stability of the drone
