【摘要】 虚拟仪器是一种基于计算机的仪器系统,具有测试、数据传输和分析的功能,也可以与网络或周边设备互联实现系统资源共享,从而节省资源。通过一种以L abW indow s/CV I为软件平台,VX I总线为硬件技术的综合测试系统,其软件采用当前流行的虚拟仪器编程软件L abW indow s/CV I,在W indow s98操作系统下编制,编程实现文件记录、文件处理及测试项目选择等功能,其测试功能全部由虚拟仪器仪表实现,既节省了实际仪器仪表,亦降低成本。更多还原

【Abstract】 Virtual instrument is a kind of system based on computer technology.It can carry out testing,data transfering and analysis tasks.It also interlinks internet and other equipment to achieve communion.It thus can save resources.We present a new type of testing system based on software for the LabWindows/CVI and hardware technology for the VXI-bus.We describe the characteristics of the technology for the VXI-bus and the virtual instrument.A software design plan has also been put forward.The software of the testing system adopts the popular programming software,the LabWindows/CVI for the virtual instrument.Programming based on Windows98 may achieve file record and file disposal and select of testing items.The testing items are accomplished by the virtual instrument.更多还原
