摘要
针对普通家庭用户设计了一款防火防盗报警系统,当环境温度、烟雾浓度达到设定的阈值或者检测到有人进入监测区域时,系统自动报警提醒用户。本系统采用DS18B20为温度采集芯片,半导体气体烟雾传感器MQ-2为烟雾采集芯片,热释电红外传感器RE200B感测是否有人进入监测区域;采用单片机STC89C52为主控模块,处理采集的信号,并与设置的阈值进行比较;采用直控按键设置环境因素的阈值;采用蜂鸣器为报警模块。实验样机测试表明,系统运行稳定、结构简单,便于操作,可用在普通家庭、小型商户等场所。
For domestic consumer,a fire alarm and anti-theft system is designed,which can alarm to remind consumer when the temperature,smoke concentration reach the setting threshold or detecting anyone is in the monitoring area. DS18B20 is used to sample the temperature signals,semiconductor gas smoke sensor MQ-2 is used to sample smoke signals,and pyroelectric infrared sensor RE200B is used to detect whether someone enters; STC89C52 is used to process the sampling signals in real time,and determines whether to alarm by comparing the setting thresholds. The thresholds can be set by the direct keys. The experiment test shows that the system is stable,simple,and easy to operate,which can be used in ordinary family and small businesses.
