【摘要】：隨著計(jì)算機(jī)技術(shù)的發(fā)展，個(gè)人電腦可以帶有多個(gè)擴(kuò)展槽，，就出現(xiàn)了插在計(jì)算機(jī)里的數(shù)據(jù)采集卡。它可以進(jìn)行一些簡(jiǎn)單的數(shù)據(jù)采集，數(shù)據(jù)采集后的處理由計(jì)算機(jī)軟件完成，這就是虛擬儀器的雛形。 虛擬儀器技術(shù)就是利用高性能的模塊化硬件，結(jié)合高效靈活的軟件來完成各種測(cè)試、測(cè)量和自動(dòng)化的應(yīng)用。他是多門技術(shù)與計(jì)算機(jī)技術(shù)結(jié)合的產(chǎn)物，是將現(xiàn)有的計(jì)算機(jī)技術(shù)與靈活易用的軟件和高性能模塊化硬件結(jié)合在一起，建立起功能強(qiáng)大又靈活易變的基于計(jì)算機(jī)的測(cè)試測(cè)量與控制系統(tǒng)來替代傳統(tǒng)儀器（價(jià)格昂貴、功能單一）的功能。虛擬儀器技術(shù)為測(cè)試測(cè)量與自動(dòng)化領(lǐng)域帶來了一場(chǎng)革新：虛擬儀器技術(shù)把現(xiàn)成即用的商業(yè)技術(shù)與創(chuàng)新的軟硬件平臺(tái)相集成，從而為嵌入式設(shè)計(jì)、工業(yè)控制以及測(cè)試和測(cè)量提供了一種嶄新的解決方案。 本論文將Multisim仿真技術(shù)、LabVIEW編程技術(shù)、網(wǎng)絡(luò)通信技術(shù)等相結(jié)合，設(shè)計(jì)了一個(gè)可供用戶遠(yuǎn)程使用的虛實(shí)互動(dòng)實(shí)驗(yàn)平臺(tái)。該平臺(tái)提供的仿真實(shí)驗(yàn)為調(diào)幅與檢波實(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)分布，用戶采用登入瀏覽器方式進(jìn)行實(shí)驗(yàn)。測(cè)控實(shí)驗(yàn)則虛實(shí)結(jié)合，通過安裝在Elvis上的數(shù)據(jù)采集卡、NI Elvis試驗(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)到虛實(shí)互動(dòng)實(shí)驗(yàn)平臺(tái)的要求。
[Abstract]:With the development of computer technology, the personal computer can have multiple expansion slots, and a data acquisition card is inserted into the computer. It can do some simple data acquisition, and the processing after data acquisition is completed by computer software. This is the prototype of virtual instruments. Virtual instrument technology is a combination of high performance modular hardware and efficient and flexible software to complete various testing, measurement and automation applications. It is the product of the combination of multi-gate technology and computer technology. By combining existing computer technology with flexible and easy-to-use software and high-performance modular hardware, a powerful and flexible computer-based test measurement and control system is built to replace traditional instruments (expensive, expensive). Virtual instrument technology brings a revolution in the field of test measurement and automation: virtual instrument technology integrates ready-made commercial technologies with innovative software and hardware platforms to design for embedded systems. Industrial control and testing and measurement provide a new solution. This paper combines Multisim simulation technology with LabVIEW programming technology, network communication technology and so on. A virtual and real interactive experimental platform is designed, which can be used remotely by users. The simulation experiment provided by the platform is an amplitude modulation and detection experiment. The simulation experiment is realized by a program written by pure software, and the network distribution is realized by the remote front panel technology provided by LabVIEW. The user carries on the experiment with the way of login browser. The test and control experiment is based on the combination of real and virtual. Through the NI Elvis test instrument installed on the Elvis and the virtual instrument provided by the platform, the user can collect the test signal on the experiment instrument remotely. The virtual instrument is used to analyze and process, and the shared variable is read to the local computer to realize the remote use of the user. After debugging, the system has stable function and can basically meet the requirements of the virtual reality interactive experimental platform.
