題目:基于單片機(jī)的智能火災(zāi)語音報警系統(tǒng)設(shè)計學(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: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“隱患險于明火,防患勝于救災(zāi),責(zé)任重于泰山”的概念設(shè)計和完善火災(zāi)自動報警系統(tǒng),將火災(zāi)消滅在萌芽狀態(tài),最大限度地減少社會財富的損失。本文設(shè)計了一種基于單片機(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
2、TGS202等,利用多傳感器信息融合技術(shù),完成語音報警的實(shí)用、可靠的單片機(jī)語音自動報警系統(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)報警和其它一些自動控制領(lǐng)域中有著廣泛的應(yīng)用前景。該系統(tǒng)能自動完成對布測點(diǎn)檢測,確認(rèn)火警后能自動報警,并顯示火情點(diǎn),記錄火災(zāi)發(fā)生時間。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)場發(fā)車巡檢信號,監(jiān)視現(xiàn)場的溫度、濃度等,并不斷反饋給報警控制器,控制器將接到的信號與內(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,可實(shí)現(xiàn)語音報警、故障自診斷、濃度顯示、報警限設(shè)置、延時報警等,是一種結(jié)構(gòu)簡單、性能穩(wěn)定、使用方便、價格低
