摘要
介绍了虚拟仪器在测试技术教学实验中的应用。在LabVIEW环境下利用通用数据采集卡组成了虚拟仪器硬件系统,利用LabVIEW提供的外部代码接口节点CIN开发了通用数据采集卡的驱动程序,给出了完整的原程序代码。设计了教学实验虚拟仪器软件系统,并通过一个实例阐述了系统的组成原理及系统功能的实现方法。实践证明,将虚拟仪器应用于测试技术教学实验,教学效果非常明显。
This paper introduces the application of virtual instruments in the experiment of measuring technique. The hardware system of virtual instrument is built with common data acquisition board in LabVIEW. The driver of common data acquisition board has been developed with Code Interface Node of LabVIEW. The whole program code is provided. With the software system of the virtual instrument for teaching experiment designed, and an example takenprineiple of the system structure and the implementing method of the system function are illustrated , Results show that the teaching effect is highly evident when the virtual instrument is applied to the experiment of measuring technique.
