摘要
为了有效地实现电工仪表功能的扩展和其自身的可维护性,设计了一款基于USB2.0和LabVIEW的新型虚拟数字电工仪表。基于虚拟仪器模块化的设计思想,搭建了基于FPGA的硬件电路,增强了扩展的功能,并采用LabVIEW图形化编程语言编写了仪表的服务程序和用户界面,可以根据实际情况修改各物理量参数,同时实现各种物理量的采集及实时显示、数据处理及存储与回放等功能。最后给出实验结果,验证该设计方案的可行性。
In order to effectively realize the expansion of electrical instrument function and its maintainability,a novel virtual digital electric instrument based on USB2.0 and LabVIEW was designed.The design idea of virtual instrument was based on modularization,the hardware circuit was built based on FPGA,to enhance the expansion of the function,and the preparation of the instrument service programand The user＇ s interface was designed by using the graphical programming language LabVIEW.,various Various physical parameters can could be modified according to the actual situation,Mmeanwhile,the system can could implement the functions that such as acquisition and real-time display of the various physical quantities,date processing,and storage and playback,and the experiment results were listed to prove the feasibility of this design.
