【摘要】 本文介绍了一种用于某型号飞机上的机载VGA系统。该系统包括VGA数据采集子系统和地面播放子系统。该系统采用FPGA技术和VxWorks实时操作系统实现的固态记录器来采集记录数据;在地面上使用专用播放软件将电子盘中所采集的数据还原成JPEG图片,并能形成视频,方便观看。该系统的成功研制,对于新型飞机的研制起到了很好的作用,此项技术也可应用到其它的行业,前景广阔。更多还原

【Abstract】 The paper introduces an airborne VGA system used on some airplane.This system contains two parts:the VGA data collection subsystem and the ground play subsystem.The system adopts a solid record device achieved by the FPGA techniques and the VxWorks real-time OS to collect record data;and we can use particular play software to revert the data of electric discs to the JPEG pictures which are turned into video to watch conveniently.The successful development of the system does do good to the development process of some airplane,and this technique can also be applied to other domains,which will have a good foreground.更多还原
