Problems solved by technology

Since the rope is flexible, the posture of the load will also change in various ways under the action of wind force during the transportation process. The force of the load causes the force of the drone to change at any time. Reliable, it needs to monitor the load in real time. The traditional technology is to install a camera on the lower side of the UAV. By transmitting the image captured by the camera back to the UAV, the power of the UAV is controlled by the flight control system of the UAV. However, if the load swings greatly and the range exceeds the monitoring range of the camera, the camera will not be able to monitor the load, which will cause the power to be unable to be adjusted

Abstract

The invention discloses an intelligent power control system based on unmanned aerial vehicle load change, which comprises an unmanned aerial vehicle body and a load sensing system, and is characterized in that the load sensing system comprises a connecting unit, a load sensing unit, an attitude auxiliary adjusting unit, a control unit and a communication unit; the connecting unit comprises an upper connecting device used for being connected with an unmanned aerial vehicle body and a lower connecting device used for being connected with a load, the control unit comprises a controller and a Beidou positioning chip connected with the controller and is used for sensing the change of the load, and the posture auxiliary adjusting unit is connected with the controller and is used for adjusting the posture of the connecting unit. The controller is connected with the unmanned aerial vehicle body through the communication unit. By arranging the load sensing unit independently arranged outside the unmanned aerial vehicle body and directly connecting the load sensing unit with the load, the sensing range of the unmanned aerial vehicle is expanded, more devices do not need to be added on the unmanned aerial vehicle, the assembly difficulty is reduced, and the adaptability is wider.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an intelligent power control system based on changes in the load of unmanned aerial vehicles. Background technique [0002] When the drone is hoisting the load, it is connected to the carried load, such as cargo, through ropes. Since the rope is flexible, the attitude of the load will also change in various ways under the action of the wind during the transportation process. The force of the load causes the force of the UAV to change at any time. It is reliable and needs to monitor the load in real time. The traditional technology is to install a camera on the underside of the drone. By transmitting the image captured by the camera back to the drone, the flight control system of the drone can control the power of the drone. However, if the load swings greatly and the range exceeds the monitoring range of the camera, the camera will not be able to monitor the loa...
