虚拟仪器的现状及发展趋势

The Current Status and the Development Trend of Virtual Instrumentation

讨论了虚拟仪器的现状和几个发展趋势,包括虚拟仪器软件的仪器化、模块化、标准化、专业化、系列化;虚拟仪器测量不确定度的给出;虚拟仪器硬件的标准化和通用化;计量校准溯源难题的解决;新概念仪器的推出与发展;针对两类最具有代表性的虚拟仪器———测量分析仪器和信号源,提出并讨论了集成仪器的概念和发展趋势。同时,讨论了虚拟仪器的优缺点。

The status and the development of virtual instrumentation (VI) is discussed in detail.It concludes that the instrumentation,the modularization,the standardization,the specialization, and the series of the software of virtual instrument.To give out of the uncertainty of VI, the standardization of the hardware of VI,the resolving of the difficult problems in measurement and calibration, and the coming forth of the new concept instrumentation of VI are also the development trends of VI.Aim at two kinds representative VI,measurement instruments and signal generators,both the concept of the integration instrumentation and its development are brought forward and discussed.At the same time,both the merit and the demerit of VI are presented.
