智能防火防盜報警系統(tǒng)設(shè)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(dāng)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(jìn)行檢測，當(dāng)有人闖入時，微波探測器檢測到盜情，然后向單片機(jī)發(fā)出中斷申請，單片機(jī)控制電話撥號電路，模擬摘機(jī)，自動撥打110，并播放預(yù)先錄制好的錄音，當(dāng)發(fā)生火災(zāi)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(shè)置所要撥打的號碼，如事主的手機(jī)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(jī)，美國公司XICOR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(jìn)行處理。系統(tǒng)從硬件和軟件兩方面進(jìn)行了抗干擾設(shè)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

Intelligent fireproof and theft-proof alarm system
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 U.S. ATMEL company's AT89C51 SCM, U.S. companies XICOR production of low-power CMOS Serial EEPROM-X25045, Canada, Mitel company's signal for DTMF / decoder chip MT8888, voice module using the U.S. ISD company's ISD1420 voice chip, a smaller overall power consumption, compatibility, and high stability.
     Through this system to identify the owner as password, the system opened only after entering the correct password to shut down the system. The system also features a self-diagnosis, failure can be automatically processed. Hardware and software systems from two aspects of the anti-interference design, so as to make it a better anti-interference capabilities, reliable system to complete the work.
Key words : intelligent fireproof and theft-proof alarm system; automatic
