【摘要】 近年来,随着人们生活水平的提高,人们的安全意识增强,对于安全防范系统也越来越重视,视频监控被广泛的应用到各行各业。而结合了远程数据采集、远程监控等功能于一体的嵌入式数字视频监控系统更是成为了视频监控的主要发展方向。研究这样一款视频监控系统,具有重要的现实意义和经济价值。嵌入式技术是计算机技术、半导体技术和微电子技术等多种先进技术的融合,已深入到各个领域,得到了广泛的应用。本文从数字视频监控的特点出发,以嵌入式操作系统为平台,提出了系统的整体设计方案。系统的核心微处理器选用Samsung公司的S3C2410芯片,这是一款基于ARM9的高性能微处理器。系统用USB摄像头进行数据采集,然后通过图像数据的网络传输,实现了远程监控的目的。本文重点阐述了硬件平台的设计与实现,针对具体的设计要求,把硬件系统分为几个具体功能模块,对每个功能模块的作用以及具体实现进行了详细的描述。并对于硬件电路图以及PCB板的设计规范进行了简要描述,整个硬件设计过程都遵循相关的设计规范。最后,论文对系统的结构和性能做出了总结和改进完善的建议。更多还原

【Abstract】 In recent years, people pay more and more attention to the security systems while the elevation of their living standards and the enhanced awareness of security, video surveillance is widely applied to all walks of life. The combination of remote data acquisition, remote monitoring, and other functions in one of the embedded digital video surveillance system is to become video surveillance’s major development directions. Research on such a video surveillance system is an important realistic significance and economic value.Embedded technology is an integration of computer technology, semiconductor technology , microelectronics technology and other advanced technology, has to reach all areas and been widely used. This article based on the characteristics of the digital video surveillance, used the embedded operating system as a platform, raised the overall design plan. The core microprocessor selected the S3C2410 chip of Samsung Corporation, which is an ARM9-based high-performance microprocessors. This system used the USB camera for data collection, and then through the image data transmission network, to achieve the purposes of remote monitoring.This article focuses on the hardware platform design and implementation of the specific design requirements. The hardware system is divided into several specific functional modules, each one has his own role. This article also detailed descript the concrete realization of each module. There have a brief description of the hardware circuit and the PCB design specifications. All hardware design process will follow the relevant design specifications. Finally, this paper concluded the structure and performance of this system, proposed advices on how to improve and perfect this system.更多还原
