1、中南大學(xué)碩士學(xué)位論文巖土工程安全監(jiān)測(cè)自動(dòng)化系統(tǒng)的研究姓名:許明情申請(qǐng)學(xué)位級(jí)別:碩士專業(yè):安全技術(shù)及工程指導(dǎo)教師:曹平20080430中南大學(xué)碩士學(xué)位論文摘要巖土工程安全監(jiān)測(cè)技術(shù)是伴隨著采礦工業(yè)、建筑工程、道路施工等的發(fā)展而逐步發(fā)展起來(lái)的。巖體和土體變形情況的監(jiān)測(cè)是交通、礦山、建筑、水利及邊坡等工程的一項(xiàng)重要課題。近年來(lái)安全監(jiān)測(cè)技術(shù)發(fā)展有了巨大的飛躍,呈現(xiàn)出“實(shí)時(shí)”、“遠(yuǎn)程”、“非接觸"的特點(diǎn)。本文針對(duì)安全監(jiān)測(cè)在巖土工程方面的應(yīng)用,以資源與安全工程學(xué)院巖土監(jiān)測(cè)實(shí)驗(yàn)室的組建為背景,主要做了以下幾個(gè)方面的工作:(1)從分析傳統(tǒng)監(jiān)測(cè)系統(tǒng)中存在的系統(tǒng)擴(kuò)展性
2、差、兼容性差、儀器設(shè)備傳輸非實(shí)時(shí)等缺陷入手,對(duì)系統(tǒng)的技術(shù)指標(biāo)、硬件和軟件等方面分析,提出了滿足“遠(yuǎn)程、實(shí)時(shí)、非接觸"的特點(diǎn)的巖土工程安全監(jiān)測(cè)系統(tǒng)實(shí)施方案。(2)在系統(tǒng)構(gòu)成的基礎(chǔ)上,詳細(xì)說(shuō)明了基于Socket網(wǎng)絡(luò)通信技術(shù)的實(shí)時(shí)通信的實(shí)現(xiàn),分別從現(xiàn)場(chǎng)監(jiān)控層和網(wǎng)絡(luò)傳輸層對(duì)數(shù)據(jù)傳輸系統(tǒng)進(jìn)行描述,采用B/S(Browser/Server,即瀏覽器/N務(wù)器)實(shí)現(xiàn)對(duì)監(jiān)測(cè)系統(tǒng)的操作,進(jìn)行數(shù)據(jù)采集。(3)分析了數(shù)據(jù)的曲線擬合、趨勢(shì)疊加、卡爾曼濾波的監(jiān)測(cè)數(shù)據(jù)預(yù)處理原理和方法并在此基礎(chǔ)上進(jìn)行數(shù)據(jù)融合。以一個(gè)長(zhǎng)期過(guò)程中監(jiān)測(cè)的數(shù)據(jù)序列為例,利用MATLAB軟件詳細(xì)說(shuō)明了多
