摘要
分析了传统仪器系统与虚拟仪器系统的特点,以水电机组振动、噪声为研究对象,提出了一种基于虚拟仪器技术的测试分析系统的设计思想及实现方法。将虚拟仪器引入水力机组振动、噪声测试分析系统,实现了对水力机组振动信号实时的数字化采集、测试、分析、控制。该系统具有人机界面友好、运行速度快、信息存储量大、开发周期短、易于维护和扩充等特点。
The characteristics of the traditional instrument system and virtual instrument system are discussed. And a way to design and implement the measurement and analysis system based on virtual instrument is introduced. Putting the virtual instrument technology into practice in the measurement and analysis of hydraulic units is discussed also,in order to realize vibration signal of hydraulic units real-time digital data acquisition ,measurement ,analysis and control.
