本科毕业论文：远程无线视频监控系统正文.doc

摘 要 近年来，随着计算机网络、通信技术和多媒体技术的发展，传统监控系统也不断向着新的方向发展并不断进行更新。论文针对公安系统的某些特殊应用场合，提出了一种基于嵌入式系统技术和现有GPRS网络资源的远程无线视频监控系统的设计方案。 论文详细阐述了基于ARM的远程监控系统的设计思想，重点介绍了监控终端的开发和研制。首先将摄像头采集到的模拟视频信号进行A/D转换，再通过BF533处理器进行图像压缩，经过图像压缩的视频信号再通过SPI传送到主控ARM处理器S3C2410来完成视频数据的无线网络发送。通过 MC55 GPRS模块接入GPRS网络，将视频不断的发给远端的监控中心。对嵌入式操作系统进行了分析与论述。最后对研究内容和系统特点进行了总结，并指出进一步研究的方向。 关键词：嵌入式技术 GPRS ARM 无线视频监控　 ABSTRACT With the rapid development of the computer network and communication technology and multimedia technology, traditional monitoring systems have greatly developed towards a new developing direction these years. For some special applications in the public security system, we presented a method to design the remote wireless video monitoring system, which is based on embedded systems technology and the existing GPRS network resources.  This thesis elaborated the design of remote monitoring system based on ARM, and highlighted the research and development of monitoring devices. First, the camera capture analog video and send it to the A/D convert module, then through the BF533 processor for image compression, and through SPI, the compressed video signals were sent to the ARM processor S3C2410 to send video data by the wireless network. Through MC55 GPRS module to connect GPRS, the video continue to be given a remote monitoring center. The embedded operating system are analyzed and discussed. Finally，the paper summarizes the main research contents and the features of the system，and then indicates the work to be done in the future.
