AbstractBecause the multi-rotor plant can vertical takeoff and landing ,and it is simple,good flexibility, the protection aircraft has been applied in many fields, including field survey, aerial photography, meteorological monitoring, pesticide spraying and so on. Through the analysis and design of the structure and key technology of the multi-rotor agricultural plant protection aircraft, through the research of the key parameters calculation of the fuselage, flight attitude design and practice, and electrical control structure design, the author designed a six-rotor agricultural plant protection aircraft with carbon fiber fuselage based on the flight control of DJ as control unit, cost-effective and easily production.

一些欧美发达国家已经将植保机广泛应用到农业领域中。远程遥控农业喷洒植保机具有结构相对简单、体型小、功能强大、低空喷洒作业面积大等特点,且同时能够负重8~10 kg的农药,每分钟可完成0.67 hm2的作业范围,作业效率是传统人工的40倍[1]。操控人员通过地面遥控单元及GPS定位系统对其飞行范围进行控制,其旋翼产生的向下气流有助于增加雾流对作物的穿透性,作业效果好,同时远距离操控施药,在大大提高了农药喷洒的安全性的同时,能够避免人与农药等有害物质的直接接触,减少人身伤害。此外,还能通过无人机搭载摄影监控云台,对农业病虫害、自然灾害等进行实时监控[2]。我国有1.218亿hm2的基本农田,农业植保任务非常巨大[3]。在我国,农业无人机的应用范围还没有普及,主要是因为目前植保无人机价格昂贵、维修成本高,这些因素制约着无人植保机技术的推广应用。……
