Abstract

The invention provides an operating method of spraying a pesticide by an unmanned aerial vehicle, which comprises the following steps: calculating parameters W and K of a spraying system and a spraying dosage P in a unit area, and transmitting W, K and P to a flight control system of the unmanned aerial vehicle through a ground station; obtaining a flight speed V of the unmanned aerial vehicle by a GPS (global positioning system) module; calculating a control voltage U of a liquid pump by the flight control system according to the parameters W and K of the spraying system, the spraying dosage P in the unit area and the flight speed V; and driving the liquid pump to work by the control voltage U of the liquid pump and spraying the pesticide through a nozzle. By adoption of the operating method, the control voltage U of the liquid pump can be calculated precisely according to the characteristics of different farm crops, pesticide types, a dilution ratio of pesticide, the spraying dosage P in the unit area and the flight speed V of the unmanned aerial vehicle, accurate control on the spraying flow is implemented, thereby making the pesticide spraying dosage in the unit area be uniform, improving the adaptation of spraying pesticides by the unmanned aerial vehicle and effectively reducing the waste of pesticides and the environment pollutions.

Description

technical field [0001] The invention relates to an operation method for spraying pesticides, in particular to an operation method for spraying pesticides by an unmanned aerial vehicle based on a GPS module, and belongs to the field of agricultural technology. Background technique [0002] As we all know, compared with the traditional manual spraying of pesticides in the field, drone spraying pesticides has significant advantages. Its operation efficiency is high, the harm of pesticides to operators is small, and the labor intensity of operators is greatly reduced. In addition, UAV spraying pesticides has high adaptability to the environment, especially unmanned helicopters have good adaptability to complex terrain. [0003] In the prior art, the moving speed of the UAV is much faster than that of the locomotive on the ground, and a slight delay in the timing of pesticide application will cause a large area of ​​pesticide leakage or excessive spraying. Therefore, it is very...
