Embodiment

[0053] Let's take a quadrotor UAV with a flight control module and a central processor as an example. The specific working steps are as follows:

[0054] 1) Function relationship fitting: such as Figure 2(a) , 2(b) As shown, it is a schematic diagram of the three-dimensional space coordinates of the drone of the present invention, and the hovering simulation of the drone is carried out in an indoor windless environment, and the rotor speed required for the hovering of the drone is measured. Change the weight of the aircraft, measure multiple sets of data, and fit the curve to obtain the mathematical relationship between the rotor speed and the lift it provides. Among them, the rotor speed has a linear relationship with the motor speed, and the motor speed and the on-board CPU control signal have a one-to-one mapping relationship. What is actually obtained is the mathematical relationship between the on-board CPU control signal and the rotor lift.

[0055] 2) Flight attitude...

Abstract

The invention belongs to the field of meteorological detection and the field of aircrafts, and discloses a wind speed and wind direction detector based on a multi-rotor unmanned aerial vehicle and a detection method thereof, and the detector comprises a data collection unit, a function relation fitting unit, a flight control unit, and a real-time wind speed and wind direction output unit. The data acquisition unit comprises a flight data acquisition module and a control signal acquisition module; the flight control unit comprises a flight attitude control module and a flight position control unit. And the real-time wind speed and direction output unit inputs airborne central processing unit control signal data and unmanned aerial vehicle wind traveling data acquired by the data acquisition unit in real time into the trained model to obtain real-time wind speed and direction. The wind speed and direction detector does not need an additional sensor, the dead weight of the unmanned aerial vehicle during working can be reduced, and the endurance is enhanced. The wind speed and direction detection method is based on the data of the unmanned aerial vehicle and is not easily interfered by the environment.

Description

technical field [0001] The invention relates to the fields of meteorological detection and aircraft, in particular to a wind speed and direction detector based on a multi-rotor unmanned aerial vehicle and a detection method thereof. Background technique [0002] Due to its low cost, easy deployment, and high maneuverability, multi-rotor UAVs can make up for the shortcomings of traditional weather detection methods in small time ranges and small spatial scales, provide data sources for detailed weather detection, and play an important role in the field of meteorological detection. played an important role. However, the traditional multi-rotor UAV-based meteorological detection method is to carry meteorological loads on the multi-rotor UAV, such as wind speed sensors and wind direction sensors. Due to the problems of poor endurance, small load, small load installation space, and poor resistance to wind and harsh environments, the multi-rotor UAV itself has problems. Traditio...
