1、居室環(huán)境監(jiān)測(cè)系統(tǒng)設(shè)計(jì)摘要生存環(huán)境的舒適與安全是人類永恒追求的物質(zhì)目標(biāo)。隨著計(jì)算機(jī)技術(shù)、通信技術(shù)、控制技術(shù)的飛速發(fā)展,人們對(duì)居住環(huán)境捉出了更高的要求。而環(huán)境監(jiān)測(cè)系統(tǒng)作為智能家居系統(tǒng)的一個(gè)重要組成部分,幫助人們實(shí)現(xiàn)家庭設(shè)備與住宅環(huán)境的監(jiān)控與管理,從I佃滿足人類對(duì)居住環(huán)境的需求。通過(guò)居室環(huán)境監(jiān)測(cè)系統(tǒng),用戶可以實(shí)時(shí)獲得居住環(huán)境的信息,如家庭的溫度、濕度,室內(nèi)異常氣體的監(jiān)測(cè)等。此居室環(huán)境實(shí)時(shí)監(jiān)測(cè)系統(tǒng),單片機(jī)80C51作為系統(tǒng)的核心,控制溫度值、濕度值的釆集、顯示和報(bào)警。單線式溫度傳感器DS18B20.電容式
2、濕度傳感器對(duì)溫度濕度分別測(cè)量并通過(guò)數(shù)碼管顯示出來(lái),當(dāng)異常氣體傳感器MQ-5采集到的值超過(guò)設(shè)置的異常氣體濃度參數(shù)范圍時(shí),報(bào)警電路就會(huì)發(fā)出報(bào)警捉示。溫度傳感器DS18B20是單線式、體積超小、碩件開(kāi)銷超低、抗干擾能力強(qiáng)、精度高,可實(shí)時(shí)根據(jù)指令給岀溫度數(shù)據(jù),可讀性高。所設(shè)計(jì)的系統(tǒng)具有可讀性高,穩(wěn)定性高,反應(yīng)速度快,測(cè)量值準(zhǔn)確的特點(diǎn)。關(guān)鍵詞:?jiǎn)纹瑱C(jī),數(shù)據(jù)采集,顯示,傳感器TheRoomEnvironmentalMonitoringSystemABSTRACTThelivingenvironmentofco
