基于无线传感网络的农业无人机航线控制系统
|
摘要
无人机是一个由飞行器、控制站、通讯设备和其它部件形成的系统,在农业领域主要应用于农药喷洒、信息监测和农业保险勘察。农业无人机在飞行过程中的实际航线与规划航路之间会存在偏差,不仅降低了作业质量,还会影响作业效率。无线传感网络是一种与无人机紧密结合的技术,可以用于对无人机的航线进行控制。为此,基于无线传感网络,设计了无人机的航线控制系统。该系统由无人机平台、传感节点、汇聚节点和控制中心4部分组成,对航线的控制通过二维坐标系跟随算法完成。试验结果表明:无线传感网络对直线和曲线航线的跟踪更加稳定,具有较高的航线控制精确度。
UAV is a system formed by aircraft,control station,communication equipment and other components. It is mainly used in agricultural field for pesticide spraying,information monitoring and agricultural insurance survey. There will be a deviation between the actual route and the planned route of the agricultural unmanned aerial vehicle during the flight,which will not only reduce the quality of the work,but also affect the operational efficiency. People have designed a variety of UAV route planning optimization algorithm for the precise control of the route laid the foundation. The wireless sensor network is a technology that is closely integrated with UAVs and can be used to control unmanned aerial vehicles. Based on the wireless sensor network,this paper designs the unmanned aerial vehicle route control system. The system consists of UAV platform,sensor node,sink node and control center composed of four parts,the control of the route through the two-dimensional coordinate system to follow the algorithm to complete. The test results show that the wireless sensor network is more stable to the straight line and the curve route,and has high route control precision.
