本发明提供一种无人机植保作业监控方法及系统,包括:在航空喷施作业过程中,获取待喷洒药剂的实际流速,并获取在实际流速下,施药管路的施药压力;根据实际流速和所述施药压力,生成流速压力曲线;基于流速压力曲线,确定无人机在航空喷施作业过程中的喷洒状态;在喷洒状态为正常的情况下,根据实际流速确定施药量。本发明运用压力传感器和流量传感器复合的方式,通过检测管路中施药流速状态,避免单一流量传感器堵塞后无法获得施药管路通断和流速信息的问题通过监控喷施作业过程中药剂的流速与管路压力,拟合生成流速压力曲线,能有效地避免因药剂堵塞流量计导致作业状态信息的误报和遗漏,提高了无人机植保作业监控的精度。
The invention provides an unmanned aerial vehicle plant protection operation monitoring method and system, and the method comprises the steps: obtaining the actual flow speed of a to-be-sprayed pesticide in an aviation spraying operation process, and obtaining the pesticide application pressure of a pesticide application pipeline at the actual flow speed; generating a flow velocity pressure curve according to the actual flow velocity and the pesticide application pressure; based on the flow velocity pressure curve, determining the spraying state of the unmanned aerial vehicle in the aviation spraying operation process; under the condition that the spraying state is normal, determining the pesticide application amount according to the actual flow speed. According to the invention, the pressure sensor and the flow sensor are combined, and the flow velocity state of pesticide application in the pipeline is detected, so that the problem that the on-off and flow velocity information of the pesticide application pipeline cannot be obtained after a single flow sensor is blocked is avoided, and a flow velocity pressure curve is fitted and generated by monitoring the flow velocity of the pesticide and the pipeline pressure in the spraying operation process; misinformation and omission of operation state information caused by blockage of the flow meter by chemicals can be effectively avoided, and the monitoring precision of plant protection operation of the unmanned aerial vehicle is improved.
