基于LabVIEW的四旋翼飞行器姿态监测系统设计

姿态监测是四旋翼飞行器实现正常飞行的主要因素之一,飞控手操控飞行但无法精准地获取实时姿态数据,存在一定的误差且准确性较低;针对以上问题,系统设计采用STM32F103RBT6单片机和MPU9250传感器采集四旋翼飞行器飞行过程中的飞行高度、飞行速度、滚转角以及俯仰角,并将数据传输给上位机LabVIEW软件平台;在虚拟软件平台对四旋翼飞行器的姿态信息进行显示、存储、报警及回放等功能;测试结果表明,姿态监测系统可以实现数据可视化,采集数据的绝对偏差值小于0.5%,提高了四旋翼飞行器姿态监测的准确性,满足了控制小型四旋翼无人机的实际需要。

Design of the attitude monitoring system of the four-rotor aircraft based on LabVIEW

The attitude monitoring is one of the main factors to realize normal flight of four-rotor aircraft. The flight controller controls the flight but can not accurately obtain the real-time attitude data. There are some errors and the accuracy is low. To solve the above problems, this paper used STM32F103RBT6 single chip microcomputer and MPU9250 sensor to collected the flight altitude, flight speed, roll angle and pitch angle of the four-rotor aircraft during flight, and transmits the data to LabVIEW software platform of the upper computer. In the virtual software platform, the attitude information of the four-rotor aircraft is displayed, stored, alerted and played back.
