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

1、Ii基于單片機(jī)的室內(nèi)環(huán)境監(jiān)控系統(tǒng)設(shè)計(jì)（軟件設(shè)計(jì)）基于單片機(jī)的室內(nèi)環(huán)境監(jiān)控系統(tǒng)設(shè)計(jì)（軟件設(shè)計(jì)）摘要摘要隨著經(jīng)濟(jì)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(lái)越差。因此，對(duì)室內(nèi)環(huán)境空氣質(zhì)量的要求越來(lái)越高。傳統(tǒng)的室內(nèi)環(huán)境監(jiān)測(cè)設(shè)施實(shí)時(shí)性差、精度低、體積大、功能單一，難以順應(yīng)現(xiàn)代經(jīng)濟(jì)發(fā)展的需求。因此，如何設(shè)計(jì)一款功能齊全、操作簡(jiǎn)單、性價(jià)比高的室內(nèi)環(huán)境監(jiān)控系統(tǒng)成為趨勢(shì)。本設(shè)計(jì)的主要內(nèi)容是實(shí)現(xiàn)一個(gè)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(cè)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(cè)。需要的軟件設(shè)計(jì)部分包括：系統(tǒng)總體軟件設(shè)計(jì)、各個(gè)模塊軟件設(shè)計(jì)，以及對(duì)應(yīng)的軟件代碼調(diào)試。各個(gè)模塊包括：各個(gè)傳感器以及數(shù)據(jù)采集與處理、報(bào)警、顯示、輸出驅(qū)動(dòng)模塊、上位機(jī)監(jiān)控中心的RS485通訊模塊及上位機(jī)的人機(jī)交互模塊等。主控制器為STC89C52單片機(jī)。AD轉(zhuǎn)換采用ADC0832將模擬量轉(zhuǎn)換為數(shù)字量。結(jié)合報(bào)警模塊和電機(jī)充當(dāng)換氣扇的輸出模塊，上位機(jī)界面用VisualBasic6

3、.0來(lái)設(shè)計(jì)，實(shí)時(shí)監(jiān)控下位機(jī)的室內(nèi)環(huán)境數(shù)據(jù)。實(shí)際中能夠完成各個(gè)傳感器對(duì)數(shù)據(jù)的采集、轉(zhuǎn)換、顯示和傳輸，基本完成各個(gè)模塊功能。通過(guò)RS485方式來(lái)通訊，數(shù)據(jù)可以通過(guò)串口調(diào)試助手和上位機(jī)界面對(duì)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
