摘　　要：SpaceWire是当前航天总线中的前沿技术,传输率大,可靠性高,可以作为构建我国新一代空间数据网络的选择.作为SpaceWire总线系统演示测试研究的一部分,本文基于嵌入式Linux系统与ARM的开发平台,利用CMOS摄像头仿真星载电子系统中的图像采集单元,提出了该平台上实现图像的采集与显示的一种方法,有效提高了采集和显示的效果,并详细介绍了此种图像采集方法的实现过程.运行结果表明,SpaceWire能有效地实现图像传输,在卫星在轨数据系统中可以用于提高总线数据传输的带宽.As a frontier technology in aerospace data bus, SpaceWire is high-speed and high reliability, and could be selected for constructing the new generation of onboard data processing network. Being part of demonstration and testing work for SpaceWire, on the embedded development platform based on Linux ＆ ARM, CMOS camera was used to simulate the image capture unit in on-board electronic systems. A method to implement the image capture and display was raised, which can improve the efficiency of image capture and display. Then it was focused on how to implement image capture and display from CMOS camera. The running result showed that SpaceWire could transmit the image data efficiently and that SpaceWire could offer increased bandwidth for satellite data system onboard.
