单片机控制的火灾自动报警器

AN AUTOMATIC FIRE ALARM CONTROLLED BY THE SINGLE-CHIP MICROCOMPUTER

摘要:

本文介绍用8031单片机最小系统,烟感、温感探测器等硬件配置和用MCS-51汇编语言编写的支持软件而研制的火灾自动报警系统。平时,它可以实时显示时间和温度。需要时,在人工干预下可以显示日历。万一发生火灾,它能及时报警和记录火灾发生的起始时间。

Abstract:

In this paper an automatic fire-alarm system is described,which is designed by using the Model-8031 monolithic microcomputer,the hardwares of smoke and temperature sensors and a supporting software programmed in the MCS-51 assembly language. The system candisplay time and temperature in normal times. When necessary, it canshow calendar through artificial intervention. In case of fire, it cansound the alarm soon after fire occurs and record the beginning time of the fire.
