虚拟仪器在电液伺服系统故障诊断中的应用

The Application of LabVIEW in Fault Diagnosis in Electro-hydraulic Servo Svstem

主要介绍了在电液伺服系统故障诊断中,设计了一套基于虚拟仪器LabVIEW的数据采集系统。虚拟仪器具有交互式用户界面和流程图式的编程风格,在监测中可以得到测量参数的数字和图形信息。测量系统程序可以随测量参数的改变而很容易的修改,因而大大提高了设计的灵活性。

This paper introduces a data sampling system based on LabVIEW in fault diagnosis in electro-hy- draulic servo system. LabVIEW has an interactive user interface and a dataflow diagram. Digital and graphic in- formation of testing parameters can be obtained timely. The program designed can be modified according to re- quirement easily. The flexibleness of instrument design is greatly improved.
