題目:基于單片機(jī)的智能火災(zāi)語(yǔ)音報(bào)警系統(tǒng)設(shè)計(jì)學(xué)校:寶雞文理學(xué)院系(院):電子電氣工程學(xué)院姓名:學(xué)號(hào):專業(yè):通信工程指導(dǎo)教師:完成日期:2015-4-20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,在我們生活的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。矚慫潤(rùn)厲釤瘞睞櫪廡賴。本文設(shè)計(jì)了一種基于單片機(jī)8051、集成語(yǔ)音芯片ISD1420、A/D轉(zhuǎn)換器
2、,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(yǔ)音報(bào)警的實(shí)用、可靠的單片機(jī)語(yǔ)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。聞創(chuàng)溝燴鐺險(xiǎn)愛氌譴凈。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(yǔ)音報(bào)警、故障自診斷、
