【摘要】：近年來,高職教育獲得了快速發(fā)展,但同時,急速擴張也帶來發(fā)展經(jīng)費的不足,造成實驗設(shè)備的規(guī)模和更新無法滿足學(xué)生需求。利用網(wǎng)絡(luò)技術(shù)和虛擬儀器技術(shù)構(gòu)建遠程虛擬實驗室,實現(xiàn)遠程測控、資源共享,是一個較為經(jīng)濟有效的解決方案。 本課題將虛擬儀器技術(shù)、網(wǎng)絡(luò)通信技術(shù)相結(jié)合,設(shè)計了一個可供用戶遠程使用的虛擬電子實驗平臺。平臺提供兩類實驗,一為仿真實驗,包括調(diào)幅與解調(diào)實驗、調(diào)頻與解調(diào)實驗、混頻實驗、信號的分解與合成實驗；一為測控實驗,包括任意信號發(fā)生器實驗、頻譜分析儀實驗、ⅡR濾波器實驗、諧波失真儀實驗。仿真實驗由純軟件編寫程序?qū)崿F(xiàn),通過LabVIEW提供的遠程前面板技術(shù)實現(xiàn)網(wǎng)絡(luò)發(fā)布,用戶采用瀏覽器方式或者“連接至遠程前面板”方式遠程運行實驗項目。測控實驗則“虛實結(jié)合”,通過安裝在服務(wù)器上的數(shù)據(jù)采集卡、NI-ELVIS實驗儀和平臺提供的虛擬儀器,用戶遠程采集實驗儀上的測試信號、運用虛擬儀器進行分析處理,并通過共享變量讀取到本地計算機中,實現(xiàn)用戶的遠程使用。經(jīng)過調(diào)試,系統(tǒng)功能穩(wěn)定,基本能達到設(shè)計要求。 本論文主要探討了遠程實驗系統(tǒng)的網(wǎng)絡(luò)通信方式、工作原理和實現(xiàn)方案。重點介紹了系統(tǒng)的軟硬件設(shè)計過程,包括各實驗項目的設(shè)計、平臺的設(shè)計及網(wǎng)絡(luò)通信的實現(xiàn),以及DAQ的安裝配置等,給出了平臺遠程運行效果。
[Abstract]:In recent years, higher vocational education has achieved rapid development, but at the same time, rapid expansion has also brought about the shortage of development funds. Because the scale and renewal of experimental equipment can not meet the needs of students, it is an economical and effective solution to construct remote virtual laboratory by using network technology and virtual instrument technology to realize remote measurement and control and resource sharing. This paper combines virtual instrument technology and network communication technology, and designs a virtual electronic experimental platform which can be used remotely by users. The platform provides two kinds of experiments, one is simulation experiment, including amplitude modulation and demodulation experiment, Frequency modulation and demodulation experiment, mixing experiment, signal decomposition and synthesis experiment; first, measurement and control experiment, including arbitrary signal generator experiment, spectrum analyzer experiment, 鈪，
