基于LabVIEW的虚拟实验系统研究

Study of virtual test system based on LabVIEW

传统的实验方式和手段由于受实验室硬件条件的限制很难满足像信号分析之类概念抽象的实验教学要求,也很难做到将实验教学引入到课堂。利用图形化编成语言LabVIEW设计开发了虚拟教学实验系统,该系统的实现彻底改变了这种局面,实现了测试技术课程实验的虚拟仿真,并将虚拟仪器直接引入到了课堂。通过将多个可完成不同实验项目的子系统进行集成,形成了一个综合实验系统。该系统可完成实验过程的模拟、实验数据的分析及结果的显示等。应用结果表明,该系统运行状况良好,对教学实践的改革与创新具有一定的指导意义。

Traditional experiment method and means are very difficult to satisfy the requirement of experiment teaching, like the signal analysis, which has the characteristic of concept abstraction, because of the hardware restriction. So it can hardly be applied in class. A virtual test system of teaching has been developed based on the graphics program language of LabVIEW. This kind of situation is thoroughly changed with the realization of this system, and the virtual simulation of test is realized finally. The comprehensive test system has been created by the way of the integration of the several sub-systems. This system can complete the simulation of experiment process, the analysis of data and result display. The application shows that this system runs well and the teaching result is remarkable, and this system is provided with guiding significance for the reforming and innovation of teaching practice.
