視頻監(jiān)控系統(tǒng)-畢業(yè)論文

摘   要

   隨著現(xiàn)代電子技術的發(fā)展，視頻監(jiān)控系統(tǒng)也逐步由模擬走向數(shù)字化。視頻監(jiān)控系統(tǒng)是安防領域中的重要組成部分，是所有安全系統(tǒng)中最關鍵的子系統(tǒng)。系統(tǒng)通過遙控攝像機，直接觀察被監(jiān)視場所的情況，同時可以把被監(jiān)視場所的情況進行同步錄像。另外，視頻監(jiān)控系統(tǒng)還可以與防盜報警系統(tǒng)等其它安全技術防范體系聯(lián)動運行，使用戶安全防范能力得到整體的提高。
      視頻監(jiān)控系統(tǒng)能在人無法直接觀察的場合，適時、清晰、真實地反映被監(jiān)視控制對象的畫面。視頻監(jiān)控系統(tǒng)已成為在現(xiàn)代化管理中監(jiān)控的最為有效的觀察工具。視頻監(jiān)控系統(tǒng)是一種全數(shù)字化、全網(wǎng)絡化的系統(tǒng)，可以同現(xiàn)有的多媒體系統(tǒng)、控制系統(tǒng)和信息系統(tǒng)集成，方便地實現(xiàn)數(shù)據(jù)和信息的共享在控制中心，只要有一個工作人員操作，就能夠觀察多個被控區(qū)域，以及遠距離區(qū)域的監(jiān)控功能。
視頻監(jiān)控系統(tǒng)由實時控制系統(tǒng)、監(jiān)視系統(tǒng)及管理信息系統(tǒng)組成。實時控制系統(tǒng)完成實時數(shù)據(jù)采集處理、存儲、反饋的功能；監(jiān)視系統(tǒng)完成對各個監(jiān)控點的全天候的監(jiān)視，能在多操作控制點上切換多路圖像；管理信息系統(tǒng)完成各類所需信息的采集、接收、傳輸、加工、處理，是整個系統(tǒng)的控制核心。
關鍵詞： 視頻監(jiān)控； 采集； 傳輸

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.
