摘　　要：研究了一种基于ARM11的视频采集无线传输系统,实现了主体家庭网关通过摄像头对各个分散房间的有效监控。系统选用ARM11内核的S3C6410作为系统处理器,CMOS摄像头OV9650作为采集端,在自主设计的硬件平台上搭建Linux软件系统,利用系统内部的V4L2提供的数据结构、应用函数等完成摄像头的采集;在传输系统方面,采用传输速度较快的WIFI-Ad-Hoc模式(端对端传输),依靠TCP/IP协议的传输方式使采集端与家庭网关之间建立连接,成功实现家庭网关对各个分散采集点视频信息的接收。This paper studies a kind of ARMll based on the video acquisition wireless transmission system, and it realizes from the main family to each dispersion effective monitoring room gateway through the camera. The system chooses ARMll kernelS3C6410 as a system processor and CMOS camera OV9650 as acquisition end. It builds Linux software system in the independent design hardware plattbrm with system internal V4L2 provided data structure and application function in order to complete camera collection; in a transmission system, it adopts the transmission speed faster WIFI-Ad-Hoc mode （end-to-end transmission）, and it relies on TCP/IP protocol transmission way to make acquisition end and establish a connection between family gateway. It can achieve successfully home gateway for decentralized acquisition point video information receiving.
