【正文】 廣州大學松田學院 畢業(yè)論文（設計）題 目 基于單片機的自動火災報警系統(tǒng)設計 火災自動報警器摘要：隨著經濟的發(fā)展，人們對防盜、防劫、防火保安設備的需求量大大增加。針對偷盜、搶劫、火災、煤氣泄漏等事故進行檢測和報警的系統(tǒng)，其需求也越來越高。本論文以MQ2型半導體電阻式煙霧傳感器和STC89C52RC單片機技術為核心并與其他電子技術相結合，設計出一種技術水平較好的煙霧報警器。其中選用MQ2型半導體可燃氣體敏感元件煙霧傳感器實現(xiàn)煙霧的檢測，具有靈敏度高、結構簡單、響應快、抗干擾能力強、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。單片機現(xiàn)在也已越來越廣泛地應用于智能儀表、工業(yè)控制、日常生活等很多領域，可以說單片機的應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，也說明我們每個人都有可能和有機會利用單片機去改造你身邊的儀器、產品、工作與生活環(huán)境。關鍵字：單片機；傳感器；信號處理；火災報警器Automatic fire alarmAbstract: With economic development, people39。s demand for antitheft, antirobbery, fire security equipment has greatly increased. For accidents such as theft, robbery, fire, gas leak detection and alarm system, and its demand is 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。 sensor。 signal processing。 fire alarm目 錄摘要………………………………………………………………………………………………1第一章、自動報警器的簡介和產生 ……………………………………………………………5 自動報警器的簡介……………………………………………………………………5 自動報警器的產生……………………………………………………………………5第二章、火災探測器的分類、基本原理……………………………
