【正文】 燕山大學(xué)本科生畢業(yè)設(shè)計(jì)（論文） II Abstract with the rapid development of munication technique and great improvement of standard of people’s living,the need of house has been changed from only the living space to multiforill needs ofquality,function,service、 and so on. The modern home with fire, electricity consumption increases, the frequency of home fires is getting higher and higher. Smoke detectors have also been widely used in various occasions. This design is bined with the use of singlechip sensor technology development and design of the smoke alarm system. The main thesis of the smoke alarm system for the various ponents are introduced, its control circuit and peripheral equipment circuit interface between technology and software have been the focus of introduction. The design of the main use of 80C51 MCU,using acoustooptic sensor NIS09 as asensitive element,using the AD574A converter and an acousticoptic alarm design consists of 5 parts:the acoustooptic sensor,A/D converter circuit,singlechip 80C51,an acousticoptic alarm circuit,LCD them,the acoustooptic sensor is the scene temperature,light ang other nonelectrical signal into an electrical signal。其中，聲光傳感器是將現(xiàn)場(chǎng)溫度、聲光等非電信號(hào)轉(zhuǎn)化為電信號(hào)；轉(zhuǎn)換電路是將完成將聲光傳感器輸出的模擬信號(hào)到數(shù)字信號(hào)的轉(zhuǎn)換。 設(shè)計(jì)中主要 使用 80C51 單片機(jī)，選用聲光傳感器 NIS09 作為敏感元件，利用 AD574A轉(zhuǎn)換器和聲光報(bào)警電路。 本設(shè)計(jì)是利用單片機(jī)結(jié)合傳感器 技術(shù)而開(kāi)發(fā)了 這一火災(zāi)煙霧報(bào)警系統(tǒng)。摘要 I 本科畢業(yè)設(shè)計(jì)（論文） 樓宇火災(zāi)探測(cè)器的設(shè)計(jì)與實(shí)現(xiàn) *** 燕 山 大 學(xué) 2021 年 6 月 摘 要 隨著信息技術(shù)的飛速發(fā)展以及人們生活水平的大幅度提高，人們對(duì)住宅的需求己叢追求簡(jiǎn)單的生存空間向著追求質(zhì)量、功能、服務(wù)等多重需求過(guò)渡。 現(xiàn)代家庭用火、用電量正在逐年增加，家庭火災(zāi)發(fā)生的頻率越來(lái)越高，火災(zāi)煙霧報(bào)警器也隨之被廣泛應(yīng)用于各種場(chǎng) 合。論文中主要煙霧報(bào)警器系統(tǒng)各個(gè)組成部分進(jìn)行了介紹，對(duì)它的主 控電路和外圍設(shè)備電路之間的接口技術(shù)，還有軟件方面進(jìn)行了重點(diǎn)介紹。整個(gè)設(shè)計(jì)由 5 大部分構(gòu)成：聲光傳感器、 A/D 轉(zhuǎn)換電路、 80C51單片機(jī)、聲光報(bào)警電路、 LCD 顯示。聲光報(bào)警模塊由單片機(jī)和報(bào)警電路組成，由單片機(jī)控制實(shí)現(xiàn)不同的聲光報(bào)警功能， LCD 可顯示現(xiàn)場(chǎng)的溫度。converting circuit is pleted to acoustooptic sensor output analog signal to digital signal acoustooptic warning module is posed of single chip and an alarm ciruit,controlled by a single chip microputer to realize different sound and lighe alarm function,LCD can display the temperature field.
