1、題目:智能溫度報警器系統(tǒng)設計學院:信息電子技術學院年級:2009專業(yè):電氣工程及其自動化姓名:王赫穎學號:0909034236指導教師:張玉峰摘要摘要本次我設計的是基于煙霧和溫度檢測的智能溫度報警器系統(tǒng)的設計,我們經(jīng)??梢栽谏虉觯瑢W校,大樓等公共場所見到的火災報警器?;馂淖詣訄缶到y(tǒng)通過一定的方式向火災報警控制器發(fā)出火災報警信號,火災報警控制器收到報警信號后,立即發(fā)出聲光報警,并打開消防聯(lián)動裝置。本設計的檢測裝置由氣體傳感器、溫度傳感器和與之配套的專用集成電路等組成,通過對現(xiàn)場的火災參數(shù)采集,模/數(shù)轉(zhuǎn)換,地址編碼,然后傳送給單片
2、機,由單片機進行相應的運算處理,判斷現(xiàn)場是否發(fā)生火災。這種信號處理方式將單片機用于火災模式判別,可以根據(jù)火災發(fā)生時,火災參數(shù)的發(fā)展變化規(guī)律來識別真假火災,不同于傳統(tǒng)單一的定值判別方式,有利于提高火災判別的準確性。無線火災傳感器硬件和軟件平臺的設計對于整個系統(tǒng)的開發(fā)與應用至關重要,作為整個系統(tǒng)的底層支持,其必然向微型化、高度集成化、網(wǎng)絡化、節(jié)能化、智能化的方向發(fā)展,近幾年,隨著計算機成本下降和微處理器體積縮小,開發(fā)和構造火災智能無線報警系統(tǒng)將有廣闊的應用前景。關鍵詞:火災自動報警系統(tǒng);煙霧監(jiān)測;控制;消防聯(lián)動佳木斯大學教務處-i-
