摘　　要：农业生产过程面临病虫草害的严重威胁,喷洒农药是较为常用的防治方法。随着农业飞行器的推广,以无人机作为载具的航空喷施发展迅速,成为当前最为理想的农药喷洒方式。无人机喷药的雾滴沉积特性对防治效果有很大影响,是当前研究的重点。为此,设计了一种无人机喷药的雾滴沉积效果检测系统,利用无线传感网络进行航线控制,进行采样点定位以及飞行速度、高度和下方风场的数据采集。结果表明:飞行速度和高度对雾滴沉积量有相似的影响,飞行速度对雾滴沉积量的影响大于飞行高度,而雾滴沉积均匀性主要受到无人机飞行速度的影响。该检测方法具有较高的准确性,可为拓宽无线传感网络的应用范围提供依据。The agricultural production process faces the serious threat of pests and weeds. Spraying pesticides is a more common control method. With the promotion of agricultural vehicles, the rapid development of aviation spraying using unmanned aerial vehicles as the carrier has become the most ideal pesticide spraying method at present. The drop deposition characteristics of UAV spraying have a great influence on the control effect, which is the focus of current research. In this paper, we design a method to detect the droplet deposition effect of UAV spraying. The wireless sensor networks are used to control the flight path, locate the sampling points, and collect the data of the flight velocity, altitude and wind field below. The results show that the flight velocity and height have a similar effect on the amount of droplet deposition. The effect of flight velocity on the amount of droplet deposition is greater than the flight height. The droplet deposition uniformity is mainly affected by the flight velocity of the UAV. The detection method has higher accuracy and can provide the basis for widening the application range of wireless sensor networks.
