摘要
为改善传统四轴飞行器体积大、不便于携带、航模遥控器操作复杂等问题,从易用性的角度出发,提出了基于WiFi控制的微型四轴飞行器设计方案。系统以STM32处理器为核心,MPU6050、HMC5883组成惯性测量单元测量飞行器姿态,上位机通过WiFi与飞行控制器进行数据交互;并引入RT-Thread嵌入式实时操作系统,以满足飞行姿态控制的实时性要求。经实验测试,飞行器能在较短时间内对上位机的操作指令进行响应,并按照指定操作稳定飞行,系统基本完成预期目标。
In order to improve the portability of the traditional four-axis aircraft and decrease the operation complexity of the aero-modeling remote control,a design of micro four-axis aircraft based on WiFi is put forward. The system uses STM32 processor as the core,and measures the flight attitude of the aircraft by an inertial measurement unit which consists of the MPU6050 and HMC5883. The date interaction between the mobile application and the control board is completed by WiFi. The RT Thread embedded RTOS is introduced to the system at the same time in order to meet the real-time requirement of the fight attitude control. The experiment results show that the aircraft can response to upper computer in a comparatively short time and fly steadily according to the specified operating. And the system basically can complete the expected goal.
