摘要:采用MEMS传感器设计了一种飞行姿态指示系统。给出了系统的原理及整体框架,重点阐述了系统的硬件电路和软件的设计。系统以32位处理器STM32F103C作为控制核心,采用MEMS加速度计和磁传感器测量各轴向的重力加速度分量和地磁强度,进而确定飞行姿态。与传统姿态指示系统相比较,该系统体积小、功耗低。试验表明该系统具有较高的可靠性,适合无人机等体积小、机动性低的飞行器。 |

Abstract:An aircraft attitude indication system based on MESM sensor is designed.The principle and whole frame of the system are discussed,and the design of the hardware circuit and software is mainly presented.The system which takes the 32-bit microprocessor as controller,calculates and gets the attitude information through measuring the acceleration of gravity and the geomagnetic horizontal intensity of the earth on each axis with MEMS accelerometer and MEMS magnetic sensor.Compared with traditional attitude indication system,this one has low power consumption and small size.The results of tests indicate that the system has high reliability,it is adaptive to use on small,lowmaneuverability aircrafts,such as unmanned plane. |
