Research on UAV Quality and Centroid Measurement System Based on STM32 Microcontroller
In this paper,a mass centroid measurement system is designed for large UAV.Firstly,mass data is meas-ured by a large range weighing sensor with flat plate and approach bridge structure,and mass and centroid are cal-culated by"three-point support weighing method".Then,the STM32 single chip microcomputer is used to collect the measurement data in real time,and then the measurement data is sent to the supreme position computer system,which is processed in real time through the principle of static moment balance,and the center of mass position is au-tomatically calculated according to the pitch Angle of the UAV,and the real-time display is displayed.The re-search shows that the system can accurately measure the mass and the position of the center of mass of large UAVs and meet the requirements of field use.
