基于單片機的室內(nèi)環(huán)境監(jiān)控系統(tǒng)設(shè)計(畢業(yè)設(shè)計論文)

1、Ii基于單片機的室內(nèi)環(huán)境監(jiān)控系統(tǒng)設(shè)計（軟件設(shè)計）基于單片機的室內(nèi)環(huán)境監(jiān)控系統(tǒng)設(shè)計（軟件設(shè)計）摘要摘要隨著經(jīng)濟持續(xù)快速的發(fā)展，人們生活水平不斷提高空氣質(zhì)量卻越來越差。因此，對室內(nèi)環(huán)境空氣質(zhì)量的要求越來越高。傳統(tǒng)的室內(nèi)環(huán)境監(jiān)測設(shè)施實時性差、精度低、體積大、功能單一，難以順應(yīng)現(xiàn)代經(jīng)濟發(fā)展的需求。因此，如何設(shè)計一款功能齊全、操作簡單、性價比高的室內(nèi)環(huán)境監(jiān)控系統(tǒng)成為趨勢。本設(shè)計的主要內(nèi)容是實現(xiàn)一個具有溫濕度、煙霧、甲醛及一氧化碳為一體的多功能室內(nèi)

2、環(huán)境監(jiān)測系統(tǒng)，要求其精度合適，適用于家庭、綜合辦公樓等室內(nèi)環(huán)境監(jiān)測。需要的軟件設(shè)計部分包括：系統(tǒng)總體軟件設(shè)計、各個模塊軟件設(shè)計，以及對應(yīng)的軟件代碼調(diào)試。各個模塊包括：各個傳感器以及數(shù)據(jù)采集與處理、報警、顯示、輸出驅(qū)動模塊、上位機監(jiān)控中心的RS485通訊模塊及上位機的人機交互模塊等。主控制器為STC89C52單片機。AD轉(zhuǎn)換采用ADC0832將模擬量轉(zhuǎn)換為數(shù)字量。結(jié)合報警模塊和電機充當換氣扇的輸出模塊，上位機界面用VisualBasic6

3、.0來設(shè)計，實時監(jiān)控下位機的室內(nèi)環(huán)境數(shù)據(jù)。實際中能夠完成各個傳感器對數(shù)據(jù)的采集、轉(zhuǎn)換、顯示和傳輸，基本完成各個模塊功能。通過RS485方式來通訊，數(shù)據(jù)可以通過串口調(diào)試助手和上位機界面對其顯示。關(guān)鍵字：關(guān)鍵字：監(jiān)控系統(tǒng)；STC89C52；溫濕度、煙霧、甲醛及一氧化碳傳感器；RS485通訊.IIDesignofindoenvironmentmonitingsystembasedonmicrocontroller(softwaredesign
