虚拟仪器的崛起是测试仪器技术的一次革命性的飞跃,是仪器领域的一个新的里程碑。虚拟仪器的核心思想是利用计算机的强大数据处理能力,使本来需要硬件实现的测量技术软件化,利用软件完成数据的采集、数据分析和数据测试处理结果的显示,以便最大程度地降低系统成本,使仪器的测试和测量及自动化工业的系统测试变得更加方便和快捷。本课题在掌握了虚拟仪器的基本结构及信号处理的相关知识基础之上,进行虚拟示波器的整体设计,对虚拟仪器的概念,结构,发展趋势进行了相关分析。
The rise of virtual instruments is a revolutionary leap in instrumentation technology and a new milestone in the field of instrumentation. The core idea of virtual instrument is to make use of the powerful data processing ability of the computer to make the measurement technology that originally needed to be realized by hardware software, to use the software to complete the data collection, data analysis and data test processing results display in order to minimize the system cost, Make the test and measurement of the instrument and system test of automation industry more convenient and quicker. The subject has mastered the basic structure of virtual instruments and signal processing based on the relevant knowledge, the overall design of the virtual oscilloscope, the concept of virtual instruments, structure, development trends were analyzed.
