摘要
本文介绍了一种适用于多种公共场所的基于单片机火灾报警系统。针对现有的分布式火灾报警系统投资大、安装麻烦、工程量大等缺点,设计了一种基于单片机的火灾报警系统。系统采用AT89C51单片机作为主控芯片,可分为主控模块、存储模块、数码管和键盘。系统下位机以AT89C51系列单片机作为主控芯片,可分为主控模块、烟感探头。该系统具有很好的可靠性和实时性,具有广泛的市场前景。
本文综合运用火灾自动报警系统观点出发将分布式控制的思想应用到报警控制系统的设计之中,采用一台AT89C51系列单片机作为系统的上位机,下位机也采用了与上位机相同的AT89C51单片机。上位机的液晶显示界面要求提供良好人机对话界面,在故障和报警时提供相应的声光报警信号和数码管显示。

Abstract
This article introduced one kind is suitable for many kinds of public place wireless fire alarm system. For existing distributed fire alarm system investments, installation problems, engineering capacity shortcomings, designed a single fire alarm system. System using AT89C51 microcontroller as master chip, can be divided into the master module,including LCD and keyboard .The system has a very good reliability and real-time performance.
This article is a combination of wireless communication technology, from the point of view will be distributed control concepts to wireless alarm control system design, PLC or the host computer the same AT89C51 microcontroller. The LCD displays the interface requires a good interactive interface, in failure and an alert provides alarming signals and LCD screen displays.
Key words: Fire Alarm; AT89C51 Microcontroller; ADC0832
