摘要
流量信号是液压系统故障检测中的重要特征信号。提出了一种使用虚拟仪器对流量信号进行采集和处理的方法,通过虚拟仪器完成了液压系统流量信号的采集、处理、结果显示及存储等。实验证明采用虚拟仪器对流量信号进行采集和处理是可行的,同时也使针对液压系统的故障检测变得简单。
Flow signal is the important characteristics of fault detection based on hydraulic system. This paper puts forward a method using virtual instrument for flow signal acquisition and processing. Through the virtual instrument, we completed acquisition, processing, the results display, storage and so on for the flow signal of hydraulic system. The test proves that acquisition and analysis of flow signal based on virtual instrument is feasible, and it makes the fault detection for hydraulic system easy.
