摘　　要：本文在简介了LabVIEW开发环境下用户事件结构的概念和应用用户事件结构时机的基础上,以Fluke8846A数字电压表为例,利用其提供的LabVIEW驱动,通过GPIB接口控制仪器实现监测电压变化报警数据采集程序,并以表格形式反映监测电压变化超限时,报警发生的时刻和电压值,此程序简单实用,提高了人机交互性能,使用非常方便,对从事自动测试程序设计者具有参考借鉴价值,读者可以直接利用程序中的原代码,减少程序设计中繁琐调试过程,经应用证明此程序运行稳定效率高。This paper simply introduces the user incident structure in LabVIEW,and takes Fluke8846A for example,elaborates the control of the instrument to monitor the voltage change with LabVIEW drive provided by itself via GPIB interface.The program can not only collect data in real-time,but also can directly write and show the warning voltage and time in table.The method mentioned in the paper is quite simple and practical,it greatly improves the performance of man-machine conversation.In the same time,it supplies a valuable reference to programmers,readers can directly use the original codes without complicated debugging.In practical application,the program runs stably and high efficiency.
