【正文】 of this system is the singlechip control devices and a variety of different types, different function of sensor, SCM according to the receiving sensor signal detection module, a corresponding control instruction, implement open, close, sound and light alarm, ventilation, and other functions, to implement the intelligent of the Windows open, close. The system microcontroller adopts ATA89S51 microcontroller, sensors humidity sensor selection, toxic gas sensors, human pyroelectric infrared sensor, speed sensor, etc., realize the detection of various kinds of information. Motor adopts dc motor. This multifunctional intelligent window can realize the following function design: when it rains outside, humidity sensor detects the signal and the signal transmission to a rain microcontroller, by single chip microputer control dc motor rotation, close the window. To prevent rain water into the interior damage to interior items. When indoor gas or smoke concentration is more than a certain concentration, the toxic gas detection sensor, the signal is transmitted to MCU, the MCU by controlling the dc motor to make Windows open automatically and open the exhaust fan, exhaust. Drive lightemitting diodes (leds) and a buzzer alarm at the same time, to remind the master handling hazardous events in time, prevent gas poisoning and fire accidents. When someone illegal invasion, human pyroelectric infrared sensor, the signal is transmitted to MCU, MCU drive lightemitting diodes (leds) and a buzzer alarm, antitheft effect, avoid indoor property losses. When it39。s living level gradually improve, intelligent control has gradually entered people39。關(guān)鍵詞：智能家居、多功能智能窗、單片機(jī)、傳感器華北科技學(xué)院畢業(yè)設(shè)計(jì)（論文）IIIIntroductionIn today39。當(dāng)室外刮風(fēng)時(shí)，風(fēng)速傳感器將此信號(hào)傳送給單片機(jī)，單片機(jī)驅(qū)動(dòng)直流電機(jī)轉(zhuǎn)動(dòng)使窗戶自動(dòng)關(guān)閉，避免大風(fēng)損壞室內(nèi)物品。同時(shí)驅(qū)動(dòng)發(fā)光二極管和蜂鳴器報(bào)警，以提醒主人及時(shí)處理危險(xiǎn)事件，防止煤氣中毒以及火災(zāi)事故的發(fā)生。防止雨水進(jìn)入室內(nèi)損毀室內(nèi)物品。電機(jī)采用直流電機(jī)。本系統(tǒng)的主要器件即為控制器件單片機(jī)和各種不同類型、不同功能的傳感器，單片機(jī)根據(jù)接收傳感器檢測(cè)模塊的信號(hào)，發(fā)出相應(yīng)的控制指令，實(shí)現(xiàn)開(kāi)、關(guān)窗，聲光報(bào)警，通風(fēng)等功能，實(shí)現(xiàn)窗戶開(kāi)、關(guān)的智能化。作為智能家居的一個(gè)方面，多功能智能窗當(dāng)然也要跟上形勢(shì)，緊扣目前主唱的綠色節(jié)能、和諧人居的主題。智能家居是以住宅為平臺(tái)，利用綜合布線技術(shù)、網(wǎng)絡(luò)通信技術(shù)、安全防范技術(shù)、自動(dòng)控制技術(shù)、音視頻技術(shù)將家居生活有關(guān)的設(shè)施集成，構(gòu)建高效的住宅設(shè)施與家庭日程事務(wù)的管理系統(tǒng)，提升家居安全性、便利性、舒適性、藝術(shù)性，并實(shí)現(xiàn)環(huán)保節(jié)能的居住環(huán)境。智能家居又稱智能住宅，在國(guó)外常用 Smart Home 表示。本設(shè)計(jì)提出了一個(gè)以 AT89S51單片機(jī)為主的多功能智能窗系統(tǒng)。例如，人在熟睡時(shí)常因有毒氣體的泄漏而導(dǎo)致生命危險(xiǎn)。但是當(dāng)前人們所使用的窗戶是否開(kāi)啟、關(guān)閉完全靠人工來(lái)實(shí)施。窗戶對(duì)居民的重要性是生活在現(xiàn)代都市人們?cè)缫岩庾R(shí)到的問(wèn)題。華北科技學(xué)院畢業(yè)設(shè)計(jì)（論文）基于單片機(jī)的多功能智能窗的設(shè)計(jì)畢業(yè)設(shè)計(jì)目錄設(shè)計(jì)總說(shuō)明
