摘要
介绍虚拟仪器的基本概念,采用一种新的虚拟仪器电压测量不确定度评定方法,先对虚拟仪器的硬件平台进行不确定度评定,而后利用软件产生符合硬件平台技术指标的仿真采样数据,利用其软件平台处理算法对数据进行处理,对处理结果进行统计分析,得到其不确定度评定结果。这种方法也适用于虚拟仪器其他测量功能的不确定度评定。
This paper introduces the postulate of virtual instrument, proposes a new uncertainty evaluation method for virtual instrument measuring voltage, firstly evaluates uncertainty for hardware of virtual instrument, and the programme which giving the emulational signal accord with the capability of hardware, deals with the emulational signal accord to measure algorithm of virtual instrument, and acquires the result of uncertainty evaluation by making statistical analysis. This method is the same with other measuring of virtual instrument.
