视频监控系统设计毕业论文上海交通大学继续教育学院毕业设计说明书毕业设计题目视频监控系统设计系电子信息工程系专业班级姓名学号指导教师年月日视频监控系统设计摘要随着现代电子技术的发展,视频监控系统也逐步由模拟走向数字化。

视频监控系统是安防领域中的重要组成部分,是所有安全系统中最关键的子系统。

系统通过遥控摄像机,直接观察被监视场所的情况,同时可以把被监视场所的情况进行同步录像。

另外,视频监控系统还可以与防盗报警系统等其它安全技术防范体系联动运行,使用户安全防范能力得到整体的提高。

本文通过阐述视频监控系统的系统组成结构、系统主要设备的性能特点、技术指标的参数,说明如何构建CCTV系统中选择性价比优秀的产品以及如何构建性能良好、技术先进、安全可靠的电视监控系统;通过数字电视监控系统的视频采集卡、嵌入式硬盘录像机的系统性能和技术参数、选择指标的比对以及模拟电视监控系统和数字电视监控系统的优缺点的比对,说明如何建设数字电视监控系统、通过比较同轴电缆、双绞线、光纤、射频调制传输的传输距离、传输频带和带宽、信号的衰减程度等的优缺点,可以在工程中有效合理的选择信号的传输方式和传输介质;通过阐述视频信号的各种压缩方式、视频采集卡的技术数据和选取标准,说明在选择利用网络传输视频信号时如何有效合理的利用网络的传输速度、获得流畅的视频流传输、清晰稳定的视频回放信号。

本文最后通过对一例校园监控系统构建的简单介绍,说明智能监控系统在实际中的应用,及其所带来的高效快捷的报警联动,让警卫人员可以对突发事件进行有效及时的处理。

1视频监控系统设计SummaryWith the development of modern electronic technology, video surveillance system is also gradually from analog to digital. Video surveillance systems are an important component in the security field, are the most critical subsystems of all security systems. System by remote camera, direct observation of the monitored sites, as well as monitoring sites are synchronized video. In addition, the video monitoring system and burglar alarm system and other security technology to prevent system linkage operation, enable user security overall capacity increase.This article through set out video monitoring system of system composition structure, and system main equipment of performance features, and technology indicators of parameter, description how building CCTV system in the select price/performance excellent of products and how building performance good, and technology advanced, and securityreliable of TV monitoring system; through digital TV monitoring systemof video collection card, and embedded hard recorder of system performance and technology parameter, and select indicators of than onand simulation TV monitoring system and digital TV monitoring system of advantages and disadvantages of than on, Description how construction digital TV monitoring system, and through comparison with axis cable,and double stranded line, and fibre, and RF modulation transmission of transmission distance, and transmission band and bandwidth, and signalof attenuation degree, of advantages and disadvantages, can inengineering in the effective reasonable of select signal of transmission way and transmission media; through set out video signal of various compression way, and video collection card of technology data and select standard, description in select uses network transmission video signalShi how effective reasonable of uses network of transmission speed, and obtained smooth of video flow transmission, and Clear and stable video playback signal.2视频监控系统设计This culminated in the adoption of a campus monitor system is abrief, describes the application of intelligent monitor and control system in practice, and the fast and efficient alarm linkage, allowing security personnel to effective and timely handling of unexpected events.Key words: closed-circuit television monitoring systems (CCTV),video compression, embedded systems3视频监控系统设计目录目录...................................................................... ........................................................................ ..... 4 第1章绪论......................................................................
