基于MEMS传感器的姿态测量应用研究

介绍了ADIS16375器件性能指标,利用STM32F103单片机搭建了一个硬件姿态采集平台,通过SPI接口实现对MEMS传感器数据读取,经单片机解算后通过数传电台发送到上位机,实时显示姿态信息。借助直升机航模进进行了行了动态测试,结果表明,该传感器在动态条件下能够准确的测定直升机航模实时姿态角,可用于小型飞行器飞控系统。

Application of MEMS in Attitude Measurement System

The performance criteria of ADIS16375 sensor were introduced.A hardware attitude acquisition platform was constructed using STM32F103 microcontrollers.The sensor data was read through SPI interface.After the microcontrollers calculation,the attitude information was sent to the host computer by digital radio,and displayed in real time.Dynamic test in the helicopter model are carried out.The results show that the sensor can accurately measure the real-time attitude angle of the helicopter model under dynamic conditions,and can be used in the flight control system of small aircraft.
