1、智能防火防盜報警系統(tǒng)設計摘要:本文介紹了住宅智能化中的防盜防火報警系統(tǒng)。智能化防盜防火報警系統(tǒng)集防盜防火功能于一體,可全天候自動檢測盜警和火警,當確定警情時自動通過電話報警。傳感器采用微波探測器和溫度探測器,分別對盜情和火情進行檢測,當有人闖入時,微波探測器檢測到盜情,然后向單片機發(fā)出中斷申請,單片機控制電話撥號電路,模擬摘機,自動撥打110,并播放預先錄制好的錄音,當發(fā)生火災時,溫度探測器檢測到火情,則自動撥打119并播放錄音,也可以自行設置所要撥打的號碼,如事主的手機號碼,錄音需自行錄制。本系統(tǒng)采用了美國ATMEL公司生產(chǎn)的AT89C51單片機,美國公司X
2、ICOR生產(chǎn)的低功耗CMOS的串行EEPROM-X25045,加拿大Mitel公司生產(chǎn)的DTMF信號編/解碼芯片MT8888,語音模塊采用美國ISD公司的ISD1420語音芯片,整體功耗較小,兼容性好,穩(wěn)定性高。本系統(tǒng)通過密碼來識別主人身份,系統(tǒng)開啟后只有輸入正確的密碼才能關(guān)閉系統(tǒng)。本系統(tǒng)同時還具有自我診斷功能,出現(xiàn)故障能自動進行處理。系統(tǒng)從硬件和軟件兩方面進行了抗干擾設計,使其具有較好的抗干擾能力,完成系統(tǒng)可靠工作。關(guān)鍵詞:智能防火防盜報警系統(tǒng);自動撥號;探測器IIIntelligentfireproofandtheft-proofalarmsystemAb
