摘要
当今社会,传统的农业植保技术已经不能很好地满足精准农业的要求,因此必须要开发新的植保技术。本文在嵌入式技术和STM32F103C8T6的基础上,设计了植保无人机系统,该植保无人机能够满足小面积作业的要求,并且系统工作可靠、操作简单、工作效率高。论文首先给出了无人机的总体设计方案,并对系统进行了硬件和软件的设计。系统的硬件电路包括:飞行控制电路、手持遥控器电路、喷洒装置单元电路。系统的软件部分采用模块化设计,对传感器数据进行互补滤波与姿态解算,并采用串级PID算法实现对无人机的姿态、位置进行控制。经过软硬件的调试,本文设计的植保无人机能够稳定并正常飞行,并实现小面积植保作业要求。
In today’s society,the traditional agricultural plant protection technology can’t meet the requirements of precision agriculture,so it must develop new plant protection technology.Based on the embedded technology and STM32F103C8T6,this paper designs a plant protection UAV system,which can meet the requirements of small area operation,and the system is reliable,simple and efficient.Firstly,the paper gives the overall design of UAV,and designs the hardware and software of the system.The hardware circuit of the system includes:flight control circuit,hand-held remote-control circuit,spraying device unit circuit.In the software part of the system,modular design is adopted,complementary filtering and attitude calculation are carried out for sensor data,and cascade PID algorithm is adopted to control the attitude and position of UAV.After the debugging of software and hardware,the UAV designed in this paper can fly stably and normally,and realize the requirements of small area plant protection.
