视频监控系统-毕业论文

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。
      视频监控系统能在人无法直接观察的场合，适时、清晰、真实地反映被监视控制对象的画面。视频监控系统已成为在现代化管理中监控的最为有效的观察工具。视频监控系统是一种全数字化、全网络化的系统，可以同现有的多媒体系统、控制系统和信息系统集成，方便地实现数据和信息的共享在控制中心，只要有一个工作人员操作，就能够观察多个被控区域，以及远距离区域的监控功能。
视频监控系统由实时控制系统、监视系统及管理信息系统组成。实时控制系统完成实时数据采集处理、存储、反馈的功能；监视系统完成对各个监控点的全天候的监视，能在多操作控制点上切换多路图像；管理信息系统完成各类所需信息的采集、接收、传输、加工、处理，是整个系统的控制核心。

Abstract

     Along with the technical development of modern electronics, the video frequency supervision system also gradually from imitate the alignment numeral to turn.The video frequency supervision system is Anne to defend the importance in the realm to constitute the part, is in all safe systems most the sub-system of  the key.The system passes the remote control camera, the direct observation is keep watch on the amenity circumstance, at the same time can is keep watch on the amenity circumstance carries on recording the elephant synchronously.Moreover, the video frequency supervision system can also with guard against theft to report to the police the system etc. other safe techniques guard against the system to move the movement, using a safety to guard against the ability to get the whole exaltation.
     The video frequency supervision system ability at the situation that person can't observe directly, well timed, portrait, really reflect to be keep watch on appearance of control the object.The video frequency supervision system has become the most valid observation tool supervise and control in modern management.The video frequency supervision system is a kind of total amount word turn, the whole network turn of system, can the together existing multi-media system, the control system and the information systems gather, carrying out the share of the data and information in the control centre expediently, the operation of only a staff member, can observe manies to is control district, and long-distance leave the supervision function of the district.
Video frequency supervision system from solid the hour controls the system, surveillance system and management the information system constitute. The solid hour controls the data for system to complete solid to collect the processing, saving, the function of the feedback,keep watch on the system completes the all-weather surveillance that orders to the each supervision, the ability is operating control point more up cut over many road pictures,Manage the information system completes each kind of to need the information to collect, receive, transmit, process, handle, is the whole control core of system.
