基于虚拟仪器的变频器性能自动测试系统的设计

Design of Inverter Characters Automatic Measurement System Based on Virtual Instruments

阐述了基于虚拟仪器的变频器控制性能自动测试系统的组成、实现方法和功能,系统采用虚拟仪器开发软件LabVIEW结合研华PCI-1712多功能高速数据采集卡设计而成,具有高速数据采集、在线分析、显示及存储等功能,数据文件能够被MATLAB接受进行数据回放或离线分析。此测试平台设计周期短,投资少、测试功能丰富、可扩展性强。

A inverter characters automatic measurement system based on Virtual Instrument is presented in this paper, Combined with a multi-function high speed data acquisition card PCI- 1712 of the ADVANTECH, the system was designed by the virtual instrument development software LABVIEW. Not only the ability of high speed data acquisition, real-time analysis, but also the ability of recording data into a file liable to MATLAB it have. Furthermore the system＇s functions can be extended easily.
