摘要
针对目前的航空航天遥感平台成本高、采样精度低、实时性不强的特点,提出了带有采集装置的四旋翼飞行器作为采样农田信息的低空平台。总结了农田土壤信息获取的主要方式与特点,指出四旋翼飞行器将是适合高密度、实时性强等特点的农田信息采集新平台。同时讨论了四旋翼飞行器的国内外研究进展,分析了带有采集装置低空平台的结构构成、惯性测量系统,研制了重量为1 200g,续航时间大于20min的低空平台样机,并提出了远地面无线传感器获取、近地面旋翼风作用和直接接触地面采集的3种新采集方式。
For the high cost of aerospace remote sensing platform,low sampling accuracy,no real-time characteristics,four-rotor aircraft with the acquisition device is proposed as a low-altitude platform sampling farmland information.The major way of getting the soil information is summarized,and it is pointed that the character of four-rotor aircraft will be suitable for high-density,realtime farmland information acquisition platform.The development of the four-rotor aircraft domestic and international is discussed,the structure and inertial measurement system of the platform is analyzed,the platform prototype with weight of 1 200 g and life time more than 20 min is developed,at last three ways of collection farmland information are designed,such as the use of wireless sensors far from ground,the use of rotor wind near the ground and the use of devices direct contacts with the ground.Aircraft platform on basis of sentinel hover technology can achieve a variety of new farmland access to information.
