植保无人飞机施药技术研究进展

Research progress on pesticide application technology of plant protection UAV

植保无人飞机是田间病虫害防治的有效方法。随着我国农业生产趋向机械化、智能化,植保无人飞机施药技术开始崛起。剖析国内外植保无人飞机在飞控技术、航路规划、旋翼下洗气流的研究、田间植保技术和安全施药技术规范方面的应用优势,梳理了植保无人飞机施药技术的研究进展。分析发展中面临的主要问题:拥有飞控研发能力的企业不多、航路规划的要求越来越高、旋翼下洗气流对雾滴运动规律研究不足、静电施药系统中核心技术理论研究不足等。同时归纳总结出植保无人飞机的复合控制方法、实时航路规划、在空间和时间维度下下洗气流的分布特征、多机合作等是未来几大发展趋势,为植保无人飞机的推广应用提供参考。

Plant protection drones are an effective method for pest control in the field.With China's agricultural production tending to mechanization,intelligence,plant protection unmanned aircraft application technology began to rise.This paper analyzes the application advantages of domestic and foreign plant protection unmanned aircraft in flight control technology,air route planning,research on air washing flow under rotors,field plant protection technology and safety application technical specifications,the research progress of plant protection drone application technology is combing.Analysis of the main problems facing development:There are not many enterprises with flight control research and development capabilities,the requirements of route planning are getting higher and higher,the air washing flow under the rotor is not enough to study the motion law of fog droplets,the core technical theory in electrostatic application system is not studied enough.et al.At the same time,the composite control method of plant protection unmanned aircraft is summarized,real-time route planning,distribution characteristics of air wash air flow under spatial and two time dimensions,multi-machine cooperation is the next few major development trends.It provides reference for the promotion and application of plant protection unmanned aircraft.
