摘要
农用植保无人机凭借其作业效率高、运行成本低、作业时间灵活、喷洒效果好等特点,逐渐取代了传统的人工喷药装置,在绿色农用植保领域得到了广泛的应用。精准施药定位系统是农用植保无人机飞行控制的"大脑"。目前,市场上绝大部分的农用植保无人机安装的是GPS定位系统。然而该系统遇到复杂环境时容易产生定位偏差,且受地形障碍物影响较大,从而导致飞行作业的精确度差、危险系数高,严重地制约了植保无人机的发展。利用双GPS与GPRS网络定位服务相结合的方式研发设计的一种在复杂环境下也能为无人机提供高精度定位服务的混合定位系统,确保了农用植保无人机施药的高效性和精准性。
Agricultural plant protection UAVs have gradually replaced traditional manual spraying devices due to their high operating efficiency,low operating cost,flexible operating time,and good spraying effect.They have been widely used in the field of green agricultural plant protection.The precision pesticide application positioning system is the"brain"of flight control for agricultural plant protection UAVs.Currently the most of agricultural plant protection UAVs on the market are installed with GPS positioning systems.However,the GPS positioning system is prone to positioning deviations when encountered with complex environments and greatly affected by terrain obstacles,which leads to poor accuracy and high risk during flight operations and seriously restricts the development of plant protection UAVs.A hybrid positioning system that can provide high-precision positioning services for UAVs in complex environments,developed and designed through the combination of dual GPS and GPRS network positioning services,ensures high-efficiency and accuracy of agricultural plant protection UAVs.
