基于ARM9的嵌入式监控系统设计

随着生活水平的不断提高,人们对个人财产以及安全防护的意识越来越强,由于嵌入式技术的不断发展,基于嵌入式的视频监控系统得以广泛应用。本系统选用iTop4412开发板作为平台,该平台搭载基于ARM-CortexA9架构的Exynos-4412微处理器,采用Linux操作系统实现软件需求,在嵌入式系统上搭建Boa Web(Boa Webserver)服务器,通过移植MJPGstreamer软件,采集摄像头数据。在ARM9平台上对U-Boot进行了移植,针对系统需求对Linux内核进行了移植与剪裁,且构建了根文件系统,搭建运行系统的嵌入式环境。使用者直接使用浏览器或手机App,可实时查看监控画面。

With the continuous improvement of living standards,people have an increasing awareness of personal property and security protection.Due to the continuous development of embedded technology,embedded video surveillance system has been widely used.The system chooses iTop4412 development board as the platform,which is equipped with Exynos-4412 microprocessor based on ARM-CortexA9 architecture,uses Linux operating system to achieve software requirements,builds Boa We bserver on embedded system,and collects camera data by transplanting MJPG-streamer software.The U-Boot is transplanted on the ARM9 platform,the Linux kernel is transplanted and cut according to the system requirements,the root file system is built,and the embedded environment of the running system is built.Thus,users can view the monitoring screen in real time by directly using the browser or mobile phone App.
