根据农作物状态监测任务需要,本文提出了运用无人飞行平台搭载光谱成像设备进行农作物状态监测的方案.通过对多种类型无人飞行器技术参数比较分析,提出了一种基于四旋翼无人飞行平台的成像光谱回传监测方案.分析了四旋翼飞行器飞行控制及稳定方法,根据任务载荷需求、结构强度要求,研究了无人飞行平台起飞重量分析及分配方法,给出了动力系统、能源系统需求估算方法.在一定安全系数和余度要求下,给出了四旋翼飞行器组件选型方法,提出了一种装机方案,并进行了起飞重量、飞行时间等指标的验证.该平台能够实现光谱图像的实时记录并回传,可满足农作物大面积动态监测要求.

According to the needs of crops conditions monitoring,the crops monitoring program using unmanned flight platform with a spectral imaging device was proposed.Utilizing a comparative analysis on multiple types aerial vehicle,an imaging spectrum return monitoring scheme,based on four-rotor unmanned aerial vehicle,was put forward.The control and stability methods of four-rotor unmanned aerial vehicle were analyzed.According to the demand of task loading and structural strength,the analyzing and distributing approaches of take-off weight were researched,and the estimation methods for the needs of power and energy system was given.Based on safety factor and redundancy requirement,the component selection scheme was given.One installed program was proposed,and the take-off weight and flying time were tested and verified.Spectral image could be recorded and returned in real time using this platform,and the requirement of dynamic monitoring for large crop areas could be satisfied.
