摘　　要：从航拍角度来说,普通的四轴飞行器是将存储卡和相机放在其上,人们无法根据四轴飞行器的视频进行调节,导致航拍效果不佳。现在好一些的四轴飞行器增加了图传功能,这样控制模块和图传模块是完全独立的,不但增加了硬件成本,也增加了四轴飞行器的重量和功耗,使得其续航时间缩短。因此,设计一种将这两个功能合在一起的四轴飞行器控制系统很有必要。要解决此问题,就需要带有操作系统的飞行器控制系统,通过改变Linux操作系统进程的优先级和时间片,能够实时响应四轴飞行器控制系统的进程。From the point of view of aerial,ordinary four axis aircraft puts both the memory card and the camera on it, and people can not see the video transmitted by the four axis aircraft, which leads to poor effect of aerial photography. Now, some kinds of better four axis aircrafts are added a new function of image transmission, but the control module and image transmission module are completely independent,which not only increases the cost of hardware of the four axis aircraft, but also increases the weight and power consumption. To resolve this problem, the four axis aircraft control system with operating system is necessary, The processes of the four axis aircraft control system can do real-time response through changing the process priority and the time slice of Linux operating system.
