摘要：隨著科學(xué)技術(shù)的發(fā)展以及人們生活水平的提高與安全意識(shí)的加強(qiáng)，家庭、企業(yè)、機(jī)關(guān)等場所的安全防范和自動(dòng)報(bào)警系統(tǒng)的研究與設(shè)計(jì)日益被科研單機(jī)和生產(chǎn)廠商所重視。
本文介紹了入侵探測與智能報(bào)警系統(tǒng)的原理及組成，通過傳感器的檢測和電話自動(dòng)撥號(hào)實(shí)現(xiàn)智能報(bào)警。本系統(tǒng)采用紅外探測元件對入侵信號(hào)進(jìn)行捕獲，當(dāng)有入侵信號(hào)時(shí)，由單片機(jī)控制中心（AT89S51）發(fā)出相應(yīng)信號(hào)控制電話接口電路，自動(dòng)撥打預(yù)設(shè)電話號(hào)碼進(jìn)行報(bào)警；系統(tǒng)的語音電路可進(jìn)行15s錄音，對警情進(jìn)行說明；同時(shí)進(jìn)行揚(yáng)聲器報(bào)警，可以起到震嚇入侵者的作用。

Abstract: According to the development of science & technology, the improvement of living standard, and the enhancement of people's security consciousness, the security and research & design of automatic alarming system of such places as homes, enterprises and organs，has been highly focused on by institutes and producers.
My paper introduces the principle and constitution of invasive detection and automatic alarm，in order to get automatic alarm through the inspection of transducer and telephone automaticdial system. The system apply infrared detection component to catch invasive signal. When a signal breaks, the relative signal sent by SCM (AT89S51) will control the phone circle, and dial the phone automatically to alarm. The recorded circle can record for 15 seconds and describe the alarming situation. At the same time, it can alarm by loudspeaker system, which can fear the intruder.
Key Words: invasive detection, alarming system, automatic dialing, AT89S51
