【摘要】：随着计算机技术的发展，个人电脑可以带有多个扩展槽，，就出现了插在计算机里的数据采集卡。它可以进行一些简单的数据采集，数据采集后的处理由计算机软件完成，这就是虚拟仪器的雏形。虚拟仪器技术就是利用高性能的模块化硬件，结合高效灵活的软件来完成各种测试、测量和自动化的应用。他是多门技术与计算机技术结合的产物，是将现有的计算机技术与灵活易用的软件和高性能模块化硬件结合在一起，建立起功能强大又灵活易变的基于计算机的测试测量与控制系统来替代传统仪器（价格昂贵、功能单一）的功能。虚拟仪器技术为测试测量与自动化领域带来了一场革新：虚拟仪器技术把现成即用的商业技术与创新的软硬件平台相集成，从而为嵌入式设计、工业控制以及测试和测量提供了一种崭新的解决方案。本论文将Multisim仿真技术、LabVIEW编程技术、网络通信技术等相结合，设计了一个可供用户远程使用的虚实互动实验平台。该平台提供的仿真实验为调幅与检波实验。仿真实验由纯软件编写程序实现，通过LabVIEW提供的远程前面板技术实现网络分布，用户采用登入浏览器方式进行实验。测控实验则虚实结合，通过安装在Elvis上的数据采集卡、NI Elvis试验仪和平台提供的虚拟仪器，用户远程采集实验仪上的测试信号、运用虚拟仪器进行分析处理，并通过共享变量读取到本地计算机中，实现用户的远程使用。经过调试，系统功能稳定，基本能达到虚实互动实验平台的要求。
[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.
