As one of the important access to get information, it’s widely used in areas including machine, magic identify, electronic technology and other39。s fields. Among them, the flame sensor has been increasingly widely used in the system of fire alarm becourse of its performance having advantages such as high sensitivity, quick response and low price. This essay concentrates on the flame resistance sensor and microcontroller technology . It has designed a new kind of the infrared fire alarm, with good performance and low price. The system adopts flame sensor resistance to perform infrared detection, which it has the advantages like high sensitivity and quick response and low price. It transforms analog signal into digital signal by means of A/D digitalanalog converter adpopt STC89C52 SCM， which reanize materials like A/D conversion, which has high speed and low energy consumption. The fire alarms could perform such function as infrared intensity of the alarm, infrared strength of the display, alarm data limits ,which central port is a bination of STC89C52 SCM and flame sensor . It is simple structure and stable performance and its convenience and inexpensive and intelligent. It is of a certain useful value. Key words:Flame sensor Infrared alarm STC89C52 SCM I 目 錄 第 1 章 緒論 1 課題研究的要求以及目的意義 1 課題研究的要求 1 課題研究的目的意義 1 國(guó)內(nèi)外研究現(xiàn)狀 1 國(guó)內(nèi)研究現(xiàn)狀 1 國(guó)外研究現(xiàn)狀 2 論文研究 內(nèi)容及創(chuàng)新點(diǎn) 3 主要研究?jī)?nèi)容 3 主要?jiǎng)?chuàng)新點(diǎn) 3 第 2 章 火災(zāi)報(bào)警器的方案設(shè)計(jì) 3 火災(zāi)報(bào)警器的設(shè)計(jì)思路 4 火焰?zhèn)鞲衅鬟x定方案 4 火焰?zhèn)鞲衅骱?jiǎn)介 4 選用火焰?zhèn)鞲衅鞯脑? 4 火焰?zhèn)鞲衅鞯姆诸? 5 火焰?zhèn)鞲衅鞯倪x定 6 火災(zāi)報(bào)警器的整體設(shè)計(jì)方案 18
