基于无线网络的多媒体监控系统的研究与设计

21世纪是计算机网络、多媒体信息处理、传输技术的飞速发展的时代,基于无线网络的多媒体监控技术将成为未来监控系统的潮流之一。目前国内外市场上,主要应用的监控系统有模拟视频监控和数字视频监控两类产品。前者虽然成熟稳定,但已经不适应数字信息高度发达的当今社会;后者以计算机技术、通信网络及图像视频压缩为核心,也是本文所研究的基于无限网络的多媒体监控系统的核心技术之一。 同时,由于过去视频监控系统价格昂贵,很多企事业单位并基本没有采用,此时在原由的建筑格局上增加监控系统在通信布线上出现困难及安全隐患。因此,研究和采用新型、高效的多媒体压缩编码方法和采用无需布线、安全可靠的无线通信网络具有很重要的现实意义。 为解决这些问题,本文以mpeg-4格式作为多媒体信息的存储格式,设计了基于IEEE802.11a/b无线网络多媒体监控系统。本文首先对视频监控技术基础作了一般性的介绍,然后详细设计了基于IEEE802.11b无线网络的多媒体监控系统的整体架构和各个功能模块。重点对IEEE802.11无线网络的传输性能和稳定性做详细测试和分析,并对系统模块进行总体设计,使读者能较全面的了解系统的功能特点和应用价值。
