Taking the vibration signals of hydropower generator sets as the objects, according with the demand of vibration monitor system, this paper completed the research and design of wave recorder for hydropower generator sets, using LabVIEW as the condition monitor development platform. This design realized real-time acquisition and real-time displaying of the vibration signals. It was able to Store, replay and analyze the signals of the specific time interval and the unusual data by spectral analysis. Finally, the design achieves the condition monitoring purpose.
