构建网络化虚拟仪器关键技术研究

Research on the Central Technologies of Constructing Virtual Networking Instrument

介绍了网络化虚拟仪器技术和构建网络化虚拟仪器所采用结构模式,结构模式包含了B/S模式和C/S模式,结合二者的优缺点提出混合C/B/S模式.探讨在Lab Windows/CVI环境下,网络化虚拟仪器的实现方式,重点研究了基于Data Socket技术构建的远程测控结构,并利用该结构通过编程得以实现,得到了预期效果.最后分析网络化虚拟仪器技术的优势,指出网络化虚拟仪器是测控领域发展的必然趋势.

This paper gives an introduction to the virtual networking instrument technology and the structural modes of virtual networking instruments, which are made up of B/S mode and C/S mode. On the basis of the advantages and defaults of the two modes, a hybrid C/B/S model is proposed. The realization of virtual networking instrument is discussed under the envi- ronment of LabWindows/CVI. The emphasis is put on the remote measurement and control structure based on DataSocket technology, through which the programming is realized, hence, the expected result. The paper has also analyzed the advantages of the virtual networking in- strument and highlighted the inevitable trend of the technology in the field of measurement and control.
