1、基于80C51智能火災語音報警系統(tǒng)設計摘要目前,隨著電子產(chǎn)品在人類生活中的使用越來越廣泛,由此引起的火災也越來越多,在我們生活得四周到處潛伏著火災隱患。為了避免火災以及減少火災造成的損失,我們必須按照“隱患險于明火,防患勝于救災,責任重于泰山”的概念設計和完善火災自動報警系統(tǒng),將火災消滅在萌芽狀態(tài),最大限度地減少社會財富的損失。本文設計了一種基于單片機8051、集成語音芯片ISD1420、A/D轉換器,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,完成語音報警的實用、可靠的單片機語音自動報
2、警系統(tǒng),著重講述了該系統(tǒng)的組成形式及工作原理。實踐表明,單片機技術在系統(tǒng)報警和其它一些自動控制領域中有著廣泛的應用前景。該系統(tǒng)能自動完成對布測點檢測,確認火警后能自動報警,并顯示火情點,記錄火災發(fā)生時間。本系統(tǒng)可安裝在各防火單位,它負責不斷地向所監(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。當發(fā)生火災時,可實現(xiàn)語音報警、故障自診斷、濃度顯示、報警限設置、延時報警等,是一種結構簡單、性能穩(wěn)定、使用方便、價格低廉、智能化的煙霧傳感器,具有一定的
