Airborne variable pesticide application system and method for agricultural unmanned aerial vehicle

The invention relates to the technical field of agricultural pesticide application, in particular to an airborne variable pesticide application system and method for an agricultural unmanned aerial vehicle. The airborne variable pesticide application system comprises the unmanned aerial vehicle, a prescription map aerial pesticide application system, a monitoring center, a GPS positioning mechanism and a meteorological station. The prescription map aerial pesticide application system is installed on the unmanned aerial vehicle and used for decision making of pesticide application prescriptions of the unmanned aerial vehicle. Decision making signals are sent to a lower computer through an upper computer, and the lower computer is used for carrying out online dynamic adjustment on the pesticide application mechanism of the unmanned aerial vehicle. The monitoring center is used for monitoring the work speed and the drifting condition of the unmanned aerial vehicle. The GPS positioning mechanism is used for positioning the geographic position of the GPS positioning mechanism. According to variable pesticide application, the system combines the advantages of equipment and decision making software to carry out prescription map generation and research on guiding variable work of pesticide application equipment, and use and popularization are facilitated.
