【正文】 摘要 I 摘 要 隨著科技的不斷進(jìn)步，特別是通信技術(shù)，計(jì)算機(jī)技術(shù)及嵌入式系統(tǒng)技術(shù)的迅猛發(fā)展，智能家居已經(jīng)開始逐步進(jìn)入尋常百姓的家庭之中。智能家居系統(tǒng)也逐步成為現(xiàn)代家庭必備的家用系統(tǒng) 。智能家居從誕生之日起，到現(xiàn)在不過短短的二、三十年時(shí)間，其功能 從單一的防盜報(bào)警， 到 現(xiàn)在已經(jīng) 擴(kuò)展 到 了 家電智能化，信息網(wǎng)絡(luò)家電，網(wǎng)絡(luò)通信，智能監(jiān)控等領(lǐng)域。在不遠(yuǎn)的將來，智能家居系統(tǒng)會(huì)提供給人們更多地方便。現(xiàn)在的智能家居系統(tǒng)旨在為人們提供一個(gè)舒適，便捷，安全，環(huán)保的家居環(huán)境。 本系統(tǒng)主要由單片機(jī)和 GSM 短信模塊組成，借助最可靠、最成熟的 GSM 移 動(dòng)網(wǎng)絡(luò)，以最直觀的中文短消息或電話形式，直接把報(bào)警地點(diǎn)的情況反映到您的手機(jī)屏幕上。它采用主動(dòng)式紅外傳感器進(jìn)行檢測，變有形的傳統(tǒng)防盜網(wǎng)防盜窗為無形，給火災(zāi)時(shí)的逃生提供方便。并配備煙霧傳感器和燃?xì)庑孤﹤鞲衅?，?shí)現(xiàn)防火、防燃?xì)庑孤┑淖饔谩? 關(guān)鍵詞 :單片機(jī)； GSM 模塊；傳感器 Abstract II Abstract With the continuous progress of science and technology , especially the rapid development in munications technology , puter technology and embedded system technology , intelligent home is gradually used by ardinary people . the intelligent system has gradually bee an essential for home system of modern family . It has been two or three decades from the birth of intelligent home and its function was continually updated from single alarm to intelligent home appliances , information work appliances , work munications , intelligent monitoring and other fields . the intelligent home system will provide more and more convenience in the near future . the modern intelligent home system is aimed at providing a fortable , convenient , safe and environmental protective home . The system is made up of MCU and ASM Modern . It will display the alarm content in Chinese directly at your mobile screen with the help of the most reliable ASM mobile work . The system adopts initiative infrared sensor to detect and it twins the traditional alarm and windows to immateriality , which is convenient for people to escape when meeting fire . Beside , the system is equipped with the smog sensor and leakiness sensor of gas and guards against fire and gas leakiness . keywords: MCU 。 GSM modem 。 sensor 目錄 III 目 錄 摘 要 ..............................................................................................................................................
