【正文】 國(guó)家高度重視消防工作,投入了巨額的資金,其消防體系已經(jīng)十分完備。進(jìn)入21世紀(jì)后,火災(zāi)造成的直接損失上升到年均十幾億元,年均死亡2000多人。alarm system based on microcontroller【ABSTRACT】Now, with electronic products used in human life more and more widely, the resulting fire, more and more, we live in fire hazards lurking around everywhere. To avoid fires and reduce fire losses, we must follow the hidden dangers fire in prevention is better than disaster relief, the responsibility is extremely heavy, the concept design and improvement of automatic fire alarm system, fire nipped in the bud, the maximum reduce the loss of social wealth. This paper design a method that use single chip puter and digital voice chip ISD1420 to realize remote voice alarm, gives out the hardware structure and software of system, Based on the singlechip microputer 80C51, and speech chip ISD1420,temperature sensor AD590 and gas sensor TGS202 are used, and the multisensors information processing method is adopted .Practice the enunciation, The singlechip microputer technique has the extensively applied foreground in system alarm and other automatic control realm. This system can automatically to monitor the points which are acute to temperature. It can also send out alarm, show the points and record the occurring time when a fire has broke out. The system can be installed in all fire units, which is responsible for continuously monitoring the site to start the inspection signal, monitor the site of temperature, concentration, and continuous feedback to the alarm controller, the controller will receive the signal and the normal memory setting value was determined by paring to determine the fire. When fire occurs, can achieve sound and light alarm, fault diagnosis, concentration display, alarm limit settings and delay alarm is a simple structure, stable performance, easy to use, inexpensive, intelligent smoke sensor, has some practical value.【Key Words】 Fire alarm,MCU ,Transducer 目 錄 1 1 1 1 2 系統(tǒng)總體方案設(shè)計(jì) 2 系統(tǒng)總體功能概述 2 系統(tǒng)硬件總體構(gòu)架 2 系統(tǒng)軟件總體構(gòu)架 3 5 系統(tǒng)核心芯片選擇 5 傳感器介紹 5 ISD1420語(yǔ)音芯片 6 80C51芯片的引腳及功能 7 A/D轉(zhuǎn)換芯片 9 數(shù)碼管顯示電路 10 單片機(jī)外圍接口電路 11 11 復(fù)位電路 11 數(shù)據(jù)采集電路 12 信號(hào)處理電路 15 報(bào)警電路 15 語(yǔ)音報(bào)警電路 15 光報(bào)警電路 16 數(shù)碼管顯示電路 17 18 軟件開(kāi)發(fā)環(huán)境 18 火災(zāi)報(bào)警系統(tǒng)程序設(shè)計(jì) 18 19 19 20 21 22致謝 23參考文獻(xiàn) 24附錄一:電路原理圖 25附錄二:系統(tǒng)程序 26 閩南理工學(xué)院本科畢業(yè)設(shè)計(jì) 我們的祖先對(duì)火加以有效的利用,不僅帶來(lái)了溫暖與光明,同時(shí)也推動(dòng)了人類(lèi)文明的向前發(fā)展。系統(tǒng)成本較低、操作方便、工作可靠穩(wěn)定,有很好的推廣價(jià)值。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。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。本設(shè)計(jì)和資料若有不實(shí)之處,本人愿承擔(dān)一切相關(guān)責(zé)任。畢業(yè)設(shè)計(jì)中文題目基于單片機(jī)的火災(zāi)報(bào)警系統(tǒng)設(shè)計(jì)英文題目Based on the firealarm system based on microcontroller系 別:電子與電氣工程系年級(jí)專(zhuān)業(yè):2010級(jí)電氣工程及其自動(dòng)化姓 名:張維勇 學(xué) 號(hào):102032103指導(dǎo)教師:于雷職 稱(chēng):講師閩南理工學(xué)院教務(wù)處制2014 年 6 月 3 日畢業(yè)設(shè)計(jì)誠(chéng)信聲明書(shū)本人鄭重聲明:在畢業(yè)設(shè)計(jì)工作中嚴(yán)格遵守學(xué)校有關(guān)規(guī)定,恪守學(xué)術(shù)規(guī)范;我所提交的畢業(yè)設(shè)計(jì)是本人在于雷指導(dǎo)教師的指導(dǎo)下獨(dú)立研究、撰寫(xiě)的成果,設(shè)計(jì)中所引用他人的文字、研究成果,均已在設(shè)計(jì)中加以說(shuō)明;在本人的畢業(yè)設(shè)計(jì)中未剽竊、抄襲他人的學(xué)術(shù)觀點(diǎn)、思想和成果,未篡改實(shí)驗(yàn)數(shù)據(jù)。學(xué)生簽名: 2014 年6月3日 基于單片機(jī)的火災(zāi)報(bào)警系統(tǒng)設(shè)計(jì)【摘要】目前,隨著電子產(chǎn)品在人類(lèi)生活中的使用越來(lái)越廣泛,由此引起的火災(zāi)也越來(lái)越多,在我們生活得四周到處潛伏著火災(zāi)隱患。本文基于單片機(jī)8051,同時(shí)結(jié)合集成語(yǔ)音芯片ISD14A/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),設(shè)計(jì)了實(shí)用、可靠的單片機(jī)語(yǔ)音自動(dòng)報(bào)警系統(tǒng)。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(chē)巡檢信號(hào),監(jiān)視現(xiàn)場(chǎng)的溫度、濃度等,并將監(jiān)測(cè)所得數(shù)據(jù)反饋至報(bào)警控制器,通過(guò)對(duì)比來(lái)判定火災(zāi)是否真的發(fā)生?!娟P(guān)鍵詞】火災(zāi)報(bào)警,單片機(jī),傳感器
