The invention relates to the technical field of unmanned aerial vehicles, and particularly discloses a plant protection unmanned aerial vehicle anti-interference excess material detection device and method.The plant protection unmanned aerial vehicle anti-interference excess material detection device comprises a machine body and a storage box, a discharging pipe is arranged at the bottom of the storage box, an upper cavity and a lower cavity are formed in the storage box, a discharging groove is formed between the lower cavity and the upper cavity, and a storage tank is installed in the upper cavity; a detection assembly is arranged in the storage box. Fertilizer is weighed through a spiral detection piece on the lower portion, when it is judged that the fertilizer exceeds a preset value range, it is indicated that materials are insufficient, at the moment, a telescopic rod is controlled through an industrial personal computer, a pressure sensor on a detection shifting rod on the upper portion is switched, and when remaining fertilizer is sufficient, a high-range pressure sensor is used; when the residual fertilizer is less, the pressure sensor with the low measuring range is switched, so that the service lives of the pressure sensor with the low measuring range and the pressure sensor with the high measuring range are ensured, and the accuracy of a detection result when the residual fertilizer is less can be ensured by using the pressure sensor with the low measuring range.

    本发明涉及无人机技术领域,具体公开了一种植保无人机抗干扰余料检测装置及方法,包括机体和储存箱,储存箱的底部设置有排料管,储存箱的内部具有上腔体和下腔体,下腔体和上腔体之间开设有下料槽,上腔体内安装有存储罐,储存箱内具有检测组件。通过下部的螺旋检测片对肥料进行称重,当判断出肥料超出低于预设值范围内时,说明物料不足,此时通过工控机对伸缩杆进行控制,对上部的检测拨杆上的压力传感器进行切换,肥料余料充足时,使用高量程压力传感器,当肥料余料较少时切换为低量程的压力传感器,保证低量程压力传感器和高量程的压力传感器的使用寿命,使用低量程压力传感器还能够保证在肥料余料较少时检测结果的准确性。
