智能防火防盗报警系统设计
摘要:本文介绍了住宅智能化中的防盗防火报警系统。智能化防盗防火报警系统集防盗防火功能于一体,可全天候自动检测盗警和火警,当确定警情时自动通过电话报警。传感器采用微波探测器和温度探测器,分别对盗情和火情进行检测,当有人闯入时,微波探测器检测到盗情,然后向单片机发出中断申请,单片机控制电话拨号电路,模拟摘机,自动拨打110,并播放预先录制好的录音,当发生火灾时,温度探测器检测到火情,则自动拨打119并播放录音,也可以自行设置所要拨打的号码,如事主的手机号码,录音需自行录制。
本系统采用了美国ATMEL公司生产的AT89C51单片机,美国公司XICOR生产的低功耗CMOS的串行EEPROMX25045,加拿大Mitel公司生产的DTMF信号编解码芯片MT8888,语音模块采用美国ISD公司的ISD1420语音芯片,整体功耗较小,兼容性好,稳定性高。
本系统通过密码来识别主人身份,系统开启后只有输入正确的密码才能关闭系统。本系统同时还具有自我诊断功能,出现故障能自动进行处理。系统从硬件和软件两方面进行了抗干扰设计,使其具有较好的抗干扰能力,完成系统可靠工作。关键词:智能防火防盗报警系统;自动拨号;探测器
