基于虚拟仪器的发电机性能测试平台的设计

Design of Generator Performance Testing Platform Based on Virtual Instrument

旨在采用集LabVIEW开发软件、普通计算机、数据采集卡、传感器等于一体的虚拟仪器技术,对发电机主要性能参数进行数据采集和分析处理。论述了数据采集系统的硬件设计方案,提出发电机各类传感器信号采集的实现方法,完成传感器信号采集前端处理电路的设计,并根据课题的实际情况和经济适用的设计原则,选取合适的数据采集卡,最后利用美国NI公司的LabVIEW软件实现发动机各种传感器波形的采集和显示。利用LabVIEW开发的数据采集系统性能稳定,测试精度较高,界面友好,用户操作方便,充分体现了虚拟仪器的优点。

The purpose of this puper is to adopt Virtual instrument technology to collect and handle the alternator property parameter.It discusses the data acquisition system,introduces the mehtod of the signal acquired of sensor in a realistic situation with an economical suitable principle, and selects the fitting and proper data acquisition card.Lastly, by using LabVIEW of the National Insturments Co,it acquires and displays wave forms of EFI engine sensors.The data acquisition system designed by LabVIEW has stable perofmrance, high accuracy, and a user-friendly interface.It fully embodies the advantages of a virtual insturment.
