1、家用防盗系统的应用设计摘要本文介绍了住宅智能化中的家用防盗报警系统。此系统可全天候自动检测盗警，当确定警情时自动通过电话报警。传感器采用微波探测器，对盗情进行检测，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，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。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MT8
2、888，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。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：家用防盗报警系统；自动拨号；探测器IIIntelligentfireproofandtheft-proofalarmsystemAbstractThisarticleintroducedinthehousetheft-proofalarm
