摘　　要：在软硬件协同设计的指导思想下,提出了在ARM微处理器平台上移植嵌入式Linux操作系统,并完成视频采集、压缩、控制等任务。为降低产品成本,系统采用ARM9微处理器S3C2410X作为主处理器,采用普通30万像素的USB摄像头作为图像采集设备,用软件对视频数据进行MPEG-4压缩。可以通过网络把数据传到中心服务器显示并保存。实现了一种体积小、成本低廉、数字化的监控解决方案,具有广泛的应用价值。Under the guidance of methodology of hardware/software co-design and with analyzing, video monitoring system is in arm microprocessor platform, and porting embedded Linux system in it. Video capturing, compression and control tasks are completed. To lower the cost of products, system uses ARM9 as the main processor, and the video capturing equipment is USB camera with the 300000 pixel, also uses software to compress the video data with MPEG-4. It can transfer data and preservation through the network. It realized one digitized monitoring solution, the volume is small, and the cost is inexpensive. The device has the widespread application value.
