【摘要】：近年來,高職教育獲得了快速發(fā)展,但同時(shí),急速擴(kuò)張也帶來發(fā)展經(jīng)費(fèi)的不足,造成實(shí)驗(yàn)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(yuǎn)程虛擬實(shí)驗(yàn)室,實(shí)現(xiàn)遠(yuǎn)程測(cè)控、資源共享,是一個(gè)較為經(jīng)濟(jì)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(jì)了一個(gè)可供用戶遠(yuǎn)程使用的虛擬電子實(shí)驗(yàn)平臺(tái)。平臺(tái)提供兩類實(shí)驗(yàn),一為仿真實(shí)驗(yàn),包括調(diào)幅與解調(diào)實(shí)驗(yàn)、調(diào)頻與解調(diào)實(shí)驗(yàn)、混頻實(shí)驗(yàn)、信號(hào)的分解與合成實(shí)驗(yàn)；一為測(cè)控實(shí)驗(yàn),包括任意信號(hào)發(fā)生器實(shí)驗(yàn)、頻譜分析儀實(shí)驗(yàn)、ⅡR濾波器實(shí)驗(yàn)、諧波失真儀實(shí)驗(yàn)。仿真實(shí)驗(yàn)由純軟件編寫程序?qū)崿F(xiàn),通過LabVIEW提供的遠(yuǎn)程前面板技術(shù)實(shí)現(xiàn)網(wǎng)絡(luò)發(fā)布,用戶采用瀏覽器方式或者“連接至遠(yuǎn)程前面板”方式遠(yuǎn)程運(yùn)行實(shí)驗(yàn)項(xiàng)目。測(cè)控實(shí)驗(yàn)則“虛實(shí)結(jié)合”,通過安裝在服務(wù)器上的數(shù)據(jù)采集卡、NI-ELVIS實(shí)驗(yàn)儀和平臺(tái)提供的虛擬儀器,用戶遠(yuǎn)程采集實(shí)驗(yàn)儀上的測(cè)試信號(hào)、運(yùn)用虛擬儀器進(jìn)行分析處理,并通過共享變量讀取到本地計(jì)算機(jī)中,實(shí)現(xiàn)用戶的遠(yuǎn)程使用。經(jīng)過調(diào)試,系統(tǒng)功能穩(wěn)定,基本能達(dá)到設(shè)計(jì)要求。 本論文主要探討了遠(yuǎn)程實(shí)驗(yàn)系統(tǒng)的網(wǎng)絡(luò)通信方式、工作原理和實(shí)現(xiàn)方案。重點(diǎn)介紹了系統(tǒng)的軟硬件設(shè)計(jì)過程,包括各實(shí)驗(yàn)項(xiàng)目的設(shè)計(jì)、平臺(tái)的設(shè)計(jì)及網(wǎng)絡(luò)通信的實(shí)現(xiàn),以及DAQ的安裝配置等,給出了平臺(tái)遠(yuǎn)程運(yùn)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，
