摘 要
在宿舍或商場的出入口中采用監視和管理系統可以進行防盜和信息提示使用。基于AT89S51單片機的控制系統包括四部分:數據采集、控制系統、時鐘電路、語音錄音電路和報音提示信息電路。該系統采用單片機進行控制,結構簡單,還可進行多種功能的擴展,如實現多機通訊,對更大的場合進行監控與管理等。 本課題介紹了以AT89S51單片機為核心的語音播報和進行實時時鐘顯示功能的系統工作原理和設計方法,詳細研究了基于AT89S51單片機監視和管理系統電路原理, 最后運用Protel99 SE軟件繪制了系統原理圖。

ABSTRACT
In the dormitory' s or in the market' s access, Using the surveillance and management system may carry on security and the information prompt use. The control system based on AT89S51 including four parts: Data acquisition , control system, electric circuit of clock、electric circuit of recording sound & play remindful information. This system base on SCM to carry on the control,which make the structure simple and carry on many kinds of expansion ,just as realizing many machine communications, monitoring and managing bigger situation and so on.
This subject introduced the AT89S51 microcontroller as the core voice alarm system works and design methods, based on a specific study about AT89S51 SCM surveillance and management system circuit principle. And finally it used Protel99 SE software schematic to draw the system. In this paper Chapter 1 Introduction first introduced the system of meaning; Chapter 2 of this issue demonstrated the design of programmes; Chapter 3 focused on the system used in the chip hardware and hardware features and characteristics of the circuit design; No. 4 Analysis of the key chapter in the design of software algorithms; Chapter 5 was the debug and the improved design .
