LabVIEW图形化环境下虚拟电压表的设计

虚拟仪器与传统仪器不同，传统仪器是由生产厂家定义制造的，具有固定的外观和功能；虚拟仪器通过软件将计算机硬件资源与仪器硬件有机地融合为一体，从而把计算机强大的计算处理能力和仪器硬件的测量、控制能力结合在一起，大大缩小了仪器硬件的成本和体积，并通过软件实现对数据的显示、存储以及分析处理．本文描述了虚拟仪器软件平台LabVIEW的特点，重点对基于LabVIEW的虚拟电压表的设计和实现进行了讨论．

DESIGN OF THE FICTITIOUS VOLTMETER UNDER LabVIEW FIGURE ENVIRONMENT

The fictitious instrument is different from the traditional instrument, the traditional instrument is defined and made by the manufacturer, having regular appearance and function. The fictitious instrument merges the resources of the computer hardware and instrument hardware as an organic whole organically througn the software, thus conbining computer strong computing ability, measurement of the instrument hardware, control ability together, have lowered the cost and size of the hardware of the instument greatly, and realized the display and storage of the data and analysed and processed the data through the software. This text has described the characteristic of fictitious instrument software platform LabVIEW, and realized discussing the desigh based on fictitious voltmeter of LabVIEW especially.
