Problems solved by technology

However, the current research and testing equipment are mainly aimed at single-rotor plant protection drones, and there is no test equipment suitable for multi-rotor plant protection drones, and the existing equipment structure for testing the rotor wind field of single-rotor plant protection drones Complicated and cumbersome to operate, for example, the Chinese invention patent with the application number "200910213355.8", which provides a mobile UAV agricultural spraying operation wind field testing equipment and testing method, it is necessary to fix the unmanned helicopter on the hydraulic pressure The telescopic rod at the front end of the telescopic cylinder is fixed on the platform, so that the UAV is in a fixed air position, and the test is completed with the help of testing instruments
The test equipment provided by this invention patent is not suitable for multi-rotor plant protection drones, because the nozzles of multi-rotor plant protection drones are usually installed on the arm below the propeller, and spray downward under the wind field formed by the propeller, while This equipment needs to place the plant protection drone on a fixed platform, which will inevitably affect the collection of the sprayed pesticides by the test equipment below, and then affect the test data; in addition, the test equipment has a complex structure, cumbersome operation, and cannot set parameters such as power and testing , it is difficult to monitor the test status and process, and the test data cannot be traced

Embodiment 1

[0047] Whether it is a multi-rotor or single-rotor plant protection drone, in the process of near-ground plant protection operations, the spiral downward swirling wind field generated by the rotor has a great impact on the spraying effect of plant protection operations. It is generated when the blades in the power system of the aircraft rotate, and the wind field formed has a great relationship with the parameters of the motor and the size of the blades. Therefore, this embodiment provides a planting protection drone spraying operation wind field test system, which can test the spraying effect under the formed wind field by simulating the attitude change during the drone operation and changing the motor speed in the power system.

[0048] This embodiment provides a planting protection drone spraying operation wind field test system, see figure 1 , Including a power supply system, a ground station, a test platform, and a power system, spray system, and flight control system on the ...

Abstract

The invention belongs to the technical field of unmanned aerial vehicles and in particular relates to a spraying operation wind field testing system and method for a plant protection unmanned aerial vehicle. The spraying operation wind field testing system for the plant protection unmanned aerial vehicle comprises a power supply system, a ground station, a testing platform, a power system, a spraying system and a flight control system, wherein the power system, the spraying system and the flight control system are arranged on the testing platform; the power supply system provides electric energy to the testing platform, the power system, the spraying system and the flight control system; the flight control system is connected with the power system and is in wireless communication with theground station; and the power system drives the testing platform to rotate and generates a corresponding wind field for the spraying system to finish spraying effect testing under the wind field. According to the spraying operation wind field testing system and method for the plant protection unmanned aerial vehicle, the structure and operation process are simple; information such as the attitudeof the testing platform and the rotation speed of the power system is monitored in real time and fed back to the ground station; and the ground station which is in wireless communication with the flight control system can monitor related parameter information in real time and save testing data for follow-up reference.

Description

Technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a wind field test system and method for spraying operations of an unmanned aerial vehicle for planting protection. Background technique [0002] The existing plant protection drones include single-rotor and multi-rotor. The forward, retreat, ascent and descent of single-rotor plant protection drones are mainly achieved by adjusting the angle of the main rotor, and steering is achieved by adjusting the tail rotor. The probability of mutual interference between the wind fields of the main rotor and the tail rotor is extremely low. The characteristic is that the wind field is unified, the downward pressure wind field is large, and the downwashing air generated by the blades can make the liquid to reach the back of the bottom of the crop, which can meet the needs of various crops such as: field crops, tall crops, fruit trees and denser crops. Job requirements. Multi-rot...
