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EEPROM-X25045,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。

Abstract
This article introduced in the house intelligent fireproof and theft-proof alarm system. intelligent fireproof and theft-proof alarm system set fireproof and theft-proof function in a box, and all-weather automatic detection the theft-alarm and the fire-alarm, then dial the police sentiment automatically with telephone call. The sensor uses the microwave detector and the temperature detector, to robs the sentiment and the state separately carries on the examination, when some people broke into, microwave detector to detect unauthorized situation, and then sent to the interruption SCM applications, MCU control telephone dial-up circuit , Simulated pick, automatically dial 110, and play pre-recorded sound recording, when the fire occurred, the temperature detector to the fire detection, automatically dial 119 and audio recording can also set up by a number to dial, such as the victim Phone number, recording own record.
     This system uses the . pany's AT89C51 SCM, . companies XICOR production of low-power CMOS Serial EEPROM-X25045, Canada, pany's signal for DTMF / decoder chip MT8888, voice module using the . pany's ISD1420 voice chip, a smaller overall power consumption, compatibility, and high stability.
