  • 基于ARMGPRS远程家用监控平台的设计与研究

    随着半导体技术的发展和信息技术以及数字化产品的普及,嵌入式系统已被应用到网络、手持通信设备、仪器仪表、国防军事以及自动化控制等各个领域。而结合视频监控的嵌入式应用系统更是应用的热点。正是顺应这一趋势,作者展开了对远程视频监控相关技术的研究,设计了基于嵌入式平台的远程视频监控系统。系统以友善之臂公司的friendly arm作为硬件平台、嵌入式linux作为软件平台、以传统的以太网来实现高速的视频数据传输实现远程视频监视、以GPRS作为扩展模块来实现远距离的用户手机报警提示。该系统主要设计应用于无人值守的家用现场环境。 论文详细的论述了基于ARM9的S3C2410A作为系统硬件平台、扩展外围的GPRS模块、视频数据采集模块和触摸屏显示模块的嵌入式应用系统。还详细的论述了在该平台上配置交叉开发环境和移植bootloader的过程,裁剪和配置嵌入式linux系统的过程。同时按照系统方案设计了视频数据采集应用软件,基于TCP/IP的以太网视频数据传输应用软件,以及基于GPRS的串口数据发送软件。系统根据现场采集的视频数据做相应的处理,启用GPRS发送警示短信息;同时用户可以根据现有接入以太网的计算机来调阅现场的视频数据信息。 最后将该监控系统应用于普通的家用环境,结果通过对现场采集的视频数据和发送的警示短信息表明该系统能够满足于同常的无人值守的家用环境。同时总结了存在的问题以及今后需要改进的方向:首先,该系统有良好的扩展性能,通过相应的总线和接口扩展可以实现智能家用电器控制系统;其次,该系统有一定的商业和社会价值。当然系统也有不足的地方,软件设计处于测试阶段,有很多需要完善的地方。最后,通过研究和实验表明:基于ARM/GPRS的远程家用监控系统具备了实时监控和即时报警功能,可以应用于实际家用监控场合。
