基于單片機(jī)的報(bào)警系統(tǒng)設(shè)計(jì)
                           
摘要：隨著人民生活水平的逐漸提高，人們對(duì)其住宅的要求不僅是居室溫馨、舒適、豪華，而是對(duì)住宅安全性的要求越來越高。本文介紹了一種操作方便、運(yùn)行可靠的家庭型智能報(bào)警系統(tǒng)。它集防盜賊入侵、防火災(zāi)等功能于一體，可實(shí)現(xiàn)自動(dòng)檢測(cè)和電話自動(dòng)報(bào)警。自動(dòng)檢測(cè)是指由探測(cè)器或傳感器實(shí)現(xiàn)對(duì)住宅的各種模擬信號(hào)進(jìn)行自動(dòng)監(jiān)測(cè),自動(dòng)電話報(bào)警是指系統(tǒng)通過電話線路自動(dòng)撥打戶主或相關(guān)部門的電話，發(fā)出語(yǔ)音求救信號(hào)。智能探測(cè)器在監(jiān)測(cè)到災(zāi)情時(shí)只輸出報(bào)警信號(hào)開關(guān)量，主機(jī)微處理器會(huì)自動(dòng)控制電話接口電路，實(shí)現(xiàn)模擬摘機(jī)，根據(jù)檢測(cè)到的不同情形，自動(dòng)撥通相關(guān)部門的電話。本項(xiàng)目方案設(shè)計(jì)遵循技術(shù)先進(jìn)、功能齊全、性能穩(wěn)定、節(jié)約成本。

Based on SCM's alarm system design Electronic and information engineering

Abstract: With the gradually improving people's living standards, people not only the requirements of their residential home is warm, comfortable and luxurious, but the domestic security of the increasingly high demand. This paper presents a convenient and reliable operation of the family-type smart alarm system. It sets the invasion anti-theft and anti-fire, and other functions in one, for automatic detection and automatic alarm call. Is automatically detected by the detector or sensor to achieve the various residential analog signals for automatic monitoring, automatic telephone warning system is automatically dial the phone lines or heads of relevant departments of the telephone, voice issued a distress signal. Smart detectors in monitoring the disaster only to the alarm signal output switching capacity, will host microprocessor control telephone interface circuits, and simulation pick, according to the detection of different circumstances, the relevant departments automatically dial the phone. The project design to follow advanced technologies, functional and stable performance, cost savings.
