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 .
