1、華中科技大學碩士學位論文基于GPRS的環(huán)境監(jiān)測網(wǎng)絡(luò)系統(tǒng)研究與實現(xiàn)姓名:劉慧韜申請學位級別:碩士專業(yè):模式識別與智能系統(tǒng)指導(dǎo)教師:齊文新20060508摘要近年來,我國科技迅猛發(fā)展,工業(yè)化程度不斷提高,但自然生態(tài)環(huán)境卻遭到了越來越嚴重的破壞,因此,政府部門決定加大污染物排放的監(jiān)控力度,建設(shè)全局性的環(huán)境監(jiān)測網(wǎng)絡(luò)。環(huán)境監(jiān)測點通常位置分散、地理條件復(fù)雜、無人值守,因此人工抄取各監(jiān)測點的數(shù)據(jù)很不方便、執(zhí)行效率低,有線方式收集各監(jiān)測點的數(shù)據(jù)投入大、布線麻煩、傳輸距離有限,因此需要一種適宜環(huán)境監(jiān)測特點的數(shù)據(jù)傳輸方式來解決監(jiān)測點數(shù)據(jù)的收集問題。同時,環(huán)境監(jiān)測工作具有很強的全局性
2、,經(jīng)常需要調(diào)用不同環(huán)境監(jiān)測區(qū)域的數(shù)據(jù)來做參考,但是現(xiàn)在沒有一個好的環(huán)境數(shù)據(jù)交互平臺。針對上述情況,研究并設(shè)計了一種基于GPRS的環(huán)境監(jiān)測網(wǎng)絡(luò)系統(tǒng),該系統(tǒng)分兩部分來實現(xiàn)。其一,設(shè)計了環(huán)境監(jiān)測區(qū)域內(nèi)部網(wǎng)絡(luò)。該網(wǎng)絡(luò)由監(jiān)測點的環(huán)境監(jiān)測儀和監(jiān)測中心的計算機構(gòu)成。采用基于ARM的S3C44B0X芯片為核心設(shè)計了監(jiān)測儀的硬件電路,在μClinux環(huán)境下進行了監(jiān)測儀應(yīng)用程序的開發(fā),通過MC35i模塊實現(xiàn)了監(jiān)測儀的GPRS網(wǎng)絡(luò)連接和與監(jiān)控中心計算機的數(shù)據(jù)通信,解決了監(jiān)測點數(shù)據(jù)的收集問題。其二,設(shè)計了全局性的環(huán)境監(jiān)測網(wǎng)絡(luò)。該網(wǎng)絡(luò)由各區(qū)域監(jiān)測中心的計算機構(gòu)成,采用B/S(瀏覽器/服務(wù)
3、器)結(jié)構(gòu)進行設(shè)計。對Web服務(wù)器進行了配置,實現(xiàn)了靜態(tài)和動態(tài)數(shù)據(jù)交互功能,滿足了環(huán)境監(jiān)測的全局性要求。系統(tǒng)已經(jīng)應(yīng)用在省級的環(huán)境監(jiān)測工作中,形成了以地、市和大型企業(yè)為環(huán)境監(jiān)測區(qū)域的全省性的環(huán)境監(jiān)測網(wǎng)絡(luò),監(jiān)測點數(shù)據(jù)上傳及時、準確,監(jiān)測區(qū)域間信息交流通暢,很好地滿足了全省環(huán)境監(jiān)測的要求。關(guān)鍵詞:環(huán)境監(jiān)測網(wǎng)絡(luò)GPRSARMWebIAbstractRecently,inourcountry,scienceandtechnologywasdevelopedrapidly,thestandofindustrializationhasgreatimprovement.But,t
