摘要
 傳統(tǒng)的閉路電視系統(tǒng)，其管理方式是人工獨立管理分布在各房間的閉路電視，不但管理過于分散而且人工勞動強(qiáng)度大，在大型的閉路電視系統(tǒng)中，該問題更加突出。本設(shè)計的閉路電視管理系統(tǒng)很好的解決了這個問題，該系統(tǒng)只需要在主機(jī)端有一個用戶便能單獨和群體控制100臺閉路電視，提高了閉路電視系統(tǒng)的管理效率，大大減輕了用戶的負(fù)擔(dān)。本次設(shè)計的閉路電視管理系統(tǒng)是一個利用單片機(jī)應(yīng)用系統(tǒng)實現(xiàn)由主機(jī)端控制分布在各個房間的終端閉路電視。單片機(jī)具有體積小、集成度高、功能強(qiáng)、抗干擾能力強(qiáng)、可靠性高、價格低廉、開發(fā)較為容易等獨特的優(yōu)點，所以采用單片機(jī)系統(tǒng)來實現(xiàn)閉路電視管理系統(tǒng)的設(shè)計，使系統(tǒng)有結(jié)構(gòu)簡單，安裝維護(hù)簡便，易于推廣等諸多優(yōu)點。本設(shè)計的閉路電視管理系統(tǒng)使用89C51單片機(jī)來實現(xiàn)對閉路電視的弱電控制強(qiáng)電，并可以根據(jù)用戶的要求獨立和群體控制100臺閉路電視。

Abstract
The traditional closed-circuit television system, its management is independent of the management of the closed-circuit television in every room, not only management but also too dispersion of labour-intensive, large-scale closed-circuit television system. the issue more prominent.The design of the CCTV monitoring system a very good solution of this issue, the system only need to have a mainframe-users will be able to separate control group and 100 closed-circuit television to improve the efficiency of the management of closed-circuit television system, greatly reducing the burden on users . The design of the CCTV management system is the use of a microcontroller applications from a mainframe-controlled distribution terminals in various rooms of the closed-circuit television. 89C51is small in size, high integration, strong function, anti-jamming ability, high reliability and low prices, relatively easy to develop unique advantages, the use of 89C51 system to achieve the design of the CCTV management system, System is simple structure, installation and maintenance is simple and easy to promote, and many other advantages.The design of the CCTV management system using the 89C51 on closed-circuit television to achieve the strong, weak control, and can be independent in accordance with the requirements of users and groups control 100 closed-circuit television.
