基于NI数据采集卡的虚拟仪器面板设计

摘要

With the computer and NI DAQPad-6016 data acquisition card as the main hardware, LabVIEW as the software development platform, NI-DAQmx library function is used to construct the multi-functional virtual instrument system which can realize the data acquisition and analysis of strain data. The system can accomplish the single channel and multi-channel data acquisition of the key point of strain measurement of structural strength test, the strain data processing and other functions. It provides a new way for the strain measurement of structural strength test, and this method will provide strong technical support for the development of test technology in structure strength test.%以计算机和NI DAQPad－6016数据采集卡为主要硬件，以LabVIEW为软件开发平台，调用NI－DAQmx库函数，设计了一种能够实现应变数据的采集与分析的多功能虚拟仪器系统，实现了对结构强度试验的关键应变测量点进行单通道、多通道数据的采集，应变数据处理等功能，为结构强度试验的应变测量方法提供了新的思路。该方法将为结构强度试验测试技术发展提供有力的技术支撑。
