摘要
介绍了一种基于LabVIEW的虚拟测频仪设计与实现。虚拟测频仪用于对现役装备的输出脉冲进行采集并给出其频率值。本文介绍了虚拟测频仪的硬件设计与软件编程实现,它采用LabVIEW编程,能同时测量多路通道,完成装备的各种试验和性能标定测试,测试数据自动存入数据库自动管理。测试精度和速度较高,适合工程使用。
This paper introduced design and realization of virtual instrument of frequency measurement based on LabVIEW.The virtual instrument is used as collection of output impulse and dispalay of value of frequency.Hardware design and software programming of the system were discussed firstly. This system adopted LabVIEW to program and could rneasurem more than one channel at the same time. It could realize various kinds of experiment and the performance calibration test. Test data would be saved into database automatically to carry out automatic data management. Whit high accuracy and fast test speed, it can be used in the engineering.
