民用小型无人机机载视频信号调理器的设计与实现

摘要

For the characteristics of civilian UAV such as short development cycle and low cost, A video signal conditioner with the core of S3C44B0X and based on embedded system ARM7 was designed in this paper according to the low cost network video capture card which was selected in the system. The network video data was made for wireless transmission through the software processing. The system detailed design was discussed and the system hardware and software design was given. The verification tests show that, the video signal conditioner was designed reasonably, meet the requirements of the wireless transmission and can be applied to other industrial control systems.%针对民用无人机研制周期短、系统成本低等特点,根据系统选用的低成本网络型视频数据采集卡,文章设计了一种基于嵌入式系统ARM7,即S3C44B0X为核心的视频信号调理器,通过对网络视频信号的软件处理,实现网络视频数据的无线传输；文章详细论述了视频调理器的设计思路,给出了硬件电路与软件的设计与实现；验证试验表明,该视频信号调理器设计合理,满足无线传输指标要求,可推广应用到其他工业控制系统中.
