基于LabVIEW的网络化虚拟仪器实验系统的设计
|
摘要
实验教学在高校工科教育中起着相当重要的作用,但是长期以来实验设备和实验教学方法的落后在很大程度上制约了实验教学质量的提高。随着微型计算机和软件技术的发展,虚拟仪器在智能化程序、处理能力、性能价格比、可操作性等方面与传统仪器相比都具有明显的技术优势,将虚拟仪器引入高校的实验教学不但可以提高测试效率和教学的质量,而且为降低实验仪器成本提供了有效的途径和方法。本论文的目的就是开发一个网络化的虚拟仪器实验教学系统,服务于工科实验教学,以提高实验教学水平和教学质量。
本论文以Internet在远程监控上的应用为研究背景,以完成网络化的实验系统为目的展开了研究。首先,阐述了国内外相关课题的现状和发展趋势,然后介绍虚拟仪器开发平台LabVIEW,接着针对NI公司生产的数据采集卡成本高这一不足,确定采用通用串行总线USB技术进行本实验系统的数据采集。充分利用高速通用串行总线(USB)所具有的传输速度快、支持热插拔、即插即用、易于扩展、占用的系统资源少等优点,将其与传统的数据采集技术相结合,设计实现了一种基于USB的集数据采集、分析、显示为一体的数据采集系统。
介绍了本数据采集系统的USB设备驱动程序的设计,并结合驱动程序完成了基于虚拟仪器LabVIEW的主机应用程序(包括虚拟示波及频谱分析仪、虚拟信号发生器、虚拟巴特沃斯滤波器、虚拟调幅波解调器、虚拟微分器和积分器、虚拟相关分析仪等)的设计。虚拟示波及频谱分析仪不但具有传统示波器的波形显示控制功能,而且还对传统示波器的功能进行了扩展,实现了参数自动测量显示、波形存储、打印和频谱分析等功能。
本文详述了LabVIEW中使用DataSocket, Web Server及远程面板技术实现网络通信的方法。最后,对论文的研究工作进行了总结和展望。
It is very important for experiment teaching in the entire teaching of high engineering institutions, but in a long period of time, the backward teaching instrument and teaching method have restricted the improvement of teaching quality in large degree. Along with the development of the microcomputer, compare with traditional instrument, the virtual instrument have the obvious technical advantage in knowledge ware, processing capability, the ratio between function and price and Maneuver ability. The introduction of the virtual instrument to the university can not only increase the efficiency and quality of testing teaching, but also provide the effective method to reduce the cost of the experiment instrument. and gradually perfect It has the peculiarity of low cost,high performance test means. The purpose of this thesis is to build a teaching testing system of virtual instruments, which can be severed to experiment teaching of high engineering institutions, and upgrade its teaching level and improve its teaching quality.
The application of internet in the long-distance monitoring was taken as research background and the accomplishment of experiment system in the internet was taken as research purpose in this paper. The development of related subject around the world was discussed firstly. Then introduces virtual instrument development software LabVIEW. To overcome the shortcom- ing of high cost which the data acquisition card produced by the NI company has, the data collection by means of Universal Serial Bus was adopted in the experiment system.A new kind of Data Acquisition System is designed in this thesis, which is based on Universal Serial Bus(USB) technology with data acquisition, analysis and display together. The advanced performance of USB with high speed, HotPlugIn, Plug and Play, easily to expand and engrossing less system resource is shown in the system.
The thesis introduced the design of the USB driver of this data acquisition system. the application program based on LabVIEW such as Virtual Oscillograph, Virtual Signal Generator, Virtual Butterworth Filter, Virtual Amplitude Modulation and Demodulation Instrument, Virtual Differentiator and Integrator, Virtual Experiment of Correlation Analysis and so on, is completed. The Virtual Oscilloscope not only has the functions achieved in traditional scope such as waveform display and control, but also achieves some expanded functions. For example, the parameters can be measured and displayed automatically, the waveform can be saved and printed, further more, the spectrum of signal can be analyzed and displayed.
This thesis details the means of realizing communication through network by DataSocket, Web Server and Remote Panels technology in LabVIEW. Finally, this thesis provides a summary of the research work and makes some recommendations for the future research.
