increasing. AT89C51 microcontroller, optional integrated temperature sensor the AD590 and gas sensor TGS202 as the sensing element, the use of multisensor information fusion technology, developed for small flats fire alarm voice digital networked alarm. SCM now has been more and more widely used in many fields of smart instrumentation, industrial control, daily life, it can be said that the application of SCM has penetrated into human life, in every corner of the work, which shows that it is work, and each of us life is closely related to, and also shows that each of us may have and the opportunity to use a microcontroller to transform you around the instruments, products, work and living environment.Keyword: Microcontroller。單片機(jī)現(xiàn)在也已越來越廣泛地應(yīng)用于智能儀表、工業(yè)控制、日常生活等很多領(lǐng)域,可以說單片機(jī)的應(yīng)用已滲透到人類的生活、工作的每一個角落,這說明它和我們每個人的工作、生活密切相關(guān),也說明我們每個人都有可能和有機(jī)會利用單片機(jī)去改造你身邊的儀器、產(chǎn)品、工作與生活環(huán)境。本論文以MQ2型半導(dǎo)體電阻式煙霧傳感器和STC89C52RC單片機(jī)技術(shù)為核心并與其他電子技術(shù)相結(jié)合,設(shè)計出一種技術(shù)水平較好的煙霧報警器。廣州大學(xué)松田學(xué)院 畢業(yè)論文(設(shè)計)題 目 基于單片機(jī)的自動火災(zāi)報警系統(tǒng)設(shè)計 火災(zāi)自動報警器摘要:隨著經(jīng)濟(jì)的發(fā)展,人們對防盜、防劫、防火保安設(shè)備的需求量大大增加。針對偷盜、搶劫、火災(zāi)、煤氣泄漏等事故進(jìn)行檢測和報警的系統(tǒng),其需求也越來越高。其中選用MQ2型半導(dǎo)體可燃?xì)怏w敏感元件煙霧傳感器實現(xiàn)煙霧的檢測,具有靈敏度高、結(jié)構(gòu)簡單、響應(yīng)快、抗干擾能力強(qiáng)、性能穩(wěn)定、智能化、實用價值高等優(yōu)點,而且價格低廉,使用壽命長。關(guān)鍵字:單片機(jī);傳感器;信號處理;火災(zāi)報警器Automatic fire alarmAbstract: With economic development, people39。 sensor。 fire alarm目 錄摘要………………………………………………………………………………………………1第一章、自動報警器的簡介和產(chǎn)生 ……………………………………………………………5 自動報警器的簡介……………………………………………………………………5 自動報警器的產(chǎn)生……………………………………………………………………5第二章、火災(zāi)探測器的分類、基本原理…………………………………………………………6 探測器的種類…………………………………………………………………………6 常用的火災(zāi)探測器基本原理…………………………………………………………7 …………………………………………………………………8第三章、煙霧檢測報警器硬件設(shè)計………………………………………………………………9 …………………………………………………
