Dedicated flight control system for multi-rotor unmanned aerial vehicle

Abstract

The invention relates to a dedicated flight control system for a multi-rotor unmanned aerial vehicle. The system comprises a multi-rotor unmanned aerial on which a liquid spraying device is carried; and ground liquid supply equipment connected with the multi-rotor unmanned aerial vehicle through a transfusion hose and used for supplying liquid, required by the liquid spraying device in work, for the multi-rotor unmanned aerial vehicle in the work process of the multi-rotor unmanned aerial vehicle; the system further comprises ground power supply equipment connected with the multi-rotor unmanned aerial vehicle through a power supply line and used for supplying electric energy for the multi-rotor unmanned aerial vehicle in the work process of the multi-rotor unmanned aerial vehicle; the multi-rotor unmanned aerial vehicle comprises an unmanned aerial vehicle comprehensive management module, a height control submodule, an airway navigation control submodule, and a spraying control submodule. The flight control for driving the multi-rotor unmanned aerial vehicle is realized, the plant protection work can be performed along a preset flight airway, the system can deal with various complex terrains, relieve the labor intensity of a remote operator, and avoid missing spraying or re-spraying of the pesticide.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a special flight control system for multi-rotor unmanned aerial vehicles. Background technique [0002] With the development trend of agricultural intensification and scale, drones have been promoted in agricultural applications due to the higher efficiency of using drones to spray pesticides than manual spraying of pesticides. In the prior art, there are mainly three types of UAVs used in agriculture: fixed-wing, single-rotor and multi-rotor UAVs. Specifically: fixed-wing UAVs are the largest in size, require a runway for take-off, and require the approval of the air traffic control department for flight routes. It is not suitable for small-scale agricultural applications; single-rotor drones have the largest paddle plane, but because the flight direction and lift are all completed by one rotor, the control is complicated, which is not conducive to ordinary peop...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing drones are operated by manual remote control, without automatic navigation system, the accuracy of spraying liquid medicine is poor, and the phenomenon of spraying leakage occurs from time to time

The UAV flight control system based on GPS navigation controls the UAV to carry out plant protection operations along the preset flight route, but the route error or unstable operation height is prone to occur during the plant protection process, which greatly affects the effect of plant protection operations. It is easy to cause pesticide leakage, heavy spraying or mist drifting seriously
