The invention discloses an operation method for spraying a pesticide by an unmanned aerial vehicle, which comprises the following steps of: acquiring a micro-meteorological change state of each site in a farmland in a flight environment of the unmanned aerial vehicle by using a meteorological detection device, and presetting a flight track and parameters of the unmanned aerial vehicle through a flight data detection device before the unmanned aerial vehicle sprays the pesticide; calculating the pesticide spraying amount of a pesticide spraying system of the unmanned aerial vehicle according to the to-be-sprayed crop type, the pesticide type, the pesticide dilution ratio and the crop growth stage; starting the unmanned aerial vehicle to take off, setting a liquid pump according to the flight parameters, controlling the voltage of the unmanned aerial vehicle to drive the liquid pump arranged in the unmanned aerial vehicle to work, and sequentially spraying the preset pesticide per unit area of each site in the farmland through each group of nozzles. According to the invention, meteorological change data in each place of the farmland can be collected and analyzed to obtain different changes of various different micrometeorology in each place of the farmland, so that flight parameters of the unmanned aerial vehicle can be preset better, and omnibearing control of the unmanned aerial vehicle on the spraying flow is realized.
本发明公开了一种无人机喷洒农药的作业方法,利用气象检测装置获取无人机飞行环境的农田内各地点的微气象变化状态,通过飞行数据检测装置对检测无人机的飞行轨道、参数进行预设在无人机喷洒农药前,根据待喷洒的农作物种类、农药种类、农药稀释比例及农作物生长阶段,计算出无人机的药物喷洒系统喷洒药物量;启动无人机起飞,根据飞行参数设定液泵控制无人机电压驱动其内部设置的液泵工作,通过各组喷头将预设的农田内各地点单位面积的喷洒农药依次喷洒出去即可。本发明可对农田各地方的内的气象变化数据进行采集与分析,得出在农田各地方的各种不同的微气象的不同变化,从而可以更好的预设无人机的飞行参数,实现其对喷洒流量的全方位控制。
