1、基于80C51智能火災(zāi)語音報(bào)警系統(tǒng)設(shè)計(jì)摘要目前，隨著電子產(chǎn)品在人類生活中的使用越來越廣泛，由此引起的火災(zāi)也越來越多，在我們生活得四周到處潛伏著火災(zāi)隱患。為了避免火災(zāi)以及減少火災(zāi)造成的損失，我們必須按照“隱患險(xiǎn)于明火，防患勝于救災(zāi)，責(zé)任重于泰山”的概念設(shè)計(jì)和完善火災(zāi)自動(dòng)報(bào)警系統(tǒng)，將火災(zāi)消滅在萌芽狀態(tài)，最大限度地減少社會(huì)財(cái)富的損失。本文設(shè)計(jì)了一種基于單片機(jī)8051、集成語音芯片ISD1420、A／D轉(zhuǎn)換器,集成溫度傳感器AD590和氣體傳感器TGS202等,利用多傳感器信息融合技術(shù),完成語音報(bào)警的實(shí)用、可靠的單片機(jī)語音自動(dòng)報(bào)警系統(tǒng),著重講述了該系統(tǒng)的組成形式及工作原理。實(shí)踐表明,單片機(jī)技
2、術(shù)在系統(tǒng)報(bào)警和其它一些自動(dòng)控制領(lǐng)域中有著廣泛的應(yīng)用前景。該系統(tǒng)能自動(dòng)完成對(duì)布測(cè)點(diǎn)檢測(cè)，確認(rèn)火警后能自動(dòng)報(bào)警，并顯示火情點(diǎn)，記錄火災(zāi)發(fā)生時(shí)間。本系統(tǒng)可安裝在各防火單位，它負(fù)責(zé)不斷地向所監(jiān)視的現(xiàn)場(chǎng)發(fā)車巡檢信號(hào)，監(jiān)視現(xiàn)場(chǎng)的溫度、濃度等，并不斷反饋給報(bào)警控制器，控制器將接到的信號(hào)與內(nèi)存的正常整定值比較、判斷確定火災(zāi)。當(dāng)發(fā)生火災(zāi)時(shí)，可實(shí)現(xiàn)語音報(bào)警、故障自診斷、濃度顯示、報(bào)警限設(shè)置、延時(shí)報(bào)警等，是一種結(jié)構(gòu)簡(jiǎn)單、性能穩(wěn)定、使用方便、價(jià)格低廉、智能化的煙霧傳感器，具有一定的實(shí)用價(jià)值。關(guān)鍵詞：火災(zāi)報(bào)警;單片機(jī);傳感器40AbstractNow,withelectronicproductsusedinh
