摘要
测试系统以LabVIEW作为开发平台,研究内容包括:信号的产生、信号的分析处理以及案例分析。概述了系统的结构框架和主程序设计,以及PCI-9111HR数据采集卡的安装和虚拟信号发生器。叙述了信号分析处理部分的功能;最后通过了两个虚拟仪器实例证明,降低了实验成本,提高了利用率。
This testing system is based on LabVIEW. This study covers signal generation, signal analysis and processing, and case studies. First, the structural frame of this system and the design procedure of main programs are simply summarized; then the installation steps of the PCI-9111HR DAQ card and virtual signal generator are ex- plained in detail, and the functions of signal analysis and processing are described. Finally, two examples about the virtual instrument is given, and the design process and the results are analyzed. It is shown that this system can low- er the experimental cost and improve utilization ratio.
