摘要
介绍了基于LabWindows/CVI的虚拟示波器设计方法,首先介绍了数据采集系统的设计,然后给出了LAN接口的设计,最后重点给出了虚拟仪器的系统软件设计。经过实例分析证明,该虚拟示波器具备了传统示波器的基本功能,各项功能均能达到指定要求。与传统示波器相比,该虚拟示波器具有开发成本低、开发周期短、升级和维护容易等优点,而且用户可以根据需要进行扩展,方便实现人机交互。
A design method of the virtual oscilloscope based on LabWindows/CVI is introduced in this paper, firstly the design of the data acquisition system is introduced, then the design method of LAN interface is given, and finally the software design of virtual instrument system is elaborated emphatically. The example analysis shows that the virtual oscilloscope possesses the basic functions of the traditional oscilloscope, which are able to meet the specified requirements. Compared with the traditional oscilloscope, the virtual oscilloscope has the advantages of lower development cost, shorter development cycle, easier upgrade and maintenance. Its users can expand it according to their needs. It is convenient to realize human-machine interaction on the virtual oscilloscope.
