基于LPC3250的小型无人机航姿系统的设计

Design of a Small UAV Heading and Attitude System Based on LPC3250

航向和姿态是无人机飞行控制系统的重要参数,传感器系统是整个无人机飞行控制系统的核心。采用LPC3250ARM9处理器、MEMS传感器以及存储器设计无人机航姿系统,完成传感器的数据采集与处理,获得无人机的航姿信息,最后进行数据传输。将Linux操作系统嵌入到无人机航姿系统中,实现系统的实时任务调度和进程管理。结果显示,该系统达到了无人机航姿系统的小型化、低功耗、高精度的目标。

Heading and attitude are the important parameter of UAV（unmanned aerial vehicle） flight control system.The sensor system is the core of the total flight control system.The UAV heading and attitude system,which is designed by LPC3250 processor based on ARM9,MEMS Sensor and memory, can achieve data acquisition,and processing,for get UAV information of heading and attitude and go on data transmission.Linux operating system is embedded in the UAV heading and attitude system to achieve system＇ realtime task scheduling and process management.The design achieves the aim of small body,low power consumption,and high precision of the UAV heading and attitude system.
