摘要
随着通信技术、控制技术的发展,远程图像显示成为现代控制系统中的一个热点。本文以ARM S3C2440为核心控制芯片,通过对嵌入式Linux内核进行的裁剪、编译,下载和处理,完成了小车控制程序、V4L2视频接口采集程序、WIFI无线通讯程序和外围模块电路的设计,系统可以实现移动环境下图像信号采集,并将图像数据通过WIFI无线网络发送至远程Windows控制端显示,实现了远程图像采集与系统控制的目的。本系统可以用于移动式远程图像监控系统。
With the development of communication technology and control technology,remote image display becomes a hot topic o modern control systems.In this paper,by using ARM S3C2440 as the core control chip and by cuting,compiling,downloading and processing embedded Linux kernel,we completed car control programs,V4L2 video interface collection programs,WIFI wireless communications programs and peripheral module circuit design,and the system can achieving image signal acquisition in the mobile envi ronment,and image sent data to the Windows control remote display through the WIFI wireless network and achieved the remote im age acquisition and system control purposes.The system can be used for mobile remote video surveillance system.
