基于无线传感网的无人机精准喷药系统研究

Research of Precision Control System of Pesticide Spraying Based on Wireless Sensor Networks

喷药无人机由飞行平台、飞行控制系统和喷药系统组成,主要用于农药的喷洒。无线传感网络是一种结合了计算、通信和传感器3种技术的产物,可实现对无人机的控制。为此,基于无线传感网络设计了喷药无人机以较低的能量遍历农作物区域的航线控制系统,通过GDOP算法对无人机的航线进行规划和控制,从而达到无人机精准喷药的目的。试验结果表明:基于无线传感网络的无人机航线规划能够使无人机以较低的能量消耗遍历农作物区域,从而达到精准喷药的目的。

UAV is a system formed by aircraft,control station,spraying station and other components.But the UAV can’t traverse the crop area efficiently,and it can lead to the waste of energy and pesticide,and environment pollution.WSN is a technology combined with calculation,communication and sensor,it can meet the control of UAV.So,based on WSN,this paper design the wireless sensor network,it can make the UAV traverse the crop area efficiently.To reach goal of precision spraying,it project and control the airline by GDOP arithmetic.The test result show that the wireless sensor network based on WSN is more efficient to traverse crop area,and meet the goal of precision spraying.
