摘　　要：为了对液压系统运行情况进行更为直观、高效的监测,文章对以电参量信息为基础的图形化实时识别技术进行了深入分析,这种液压系统识别技术利用Hilbert变换,对电参量基频分量加以迅速提取,从而使得该监测系统有着更高的实时性;同时利用李萨如图形方法,对该电参量信息加以科学融合,由此使得该识别技术具有实时性与图形化。最后借助于LabView系统对该识别系统展开设计,将液压系统极限工况作为试验对象,对该开发技术的实用性与稳定性进行验证,从而为液压系统状态识别系统提供创新的开发路径。In order to monitor the operation of the hydraulic system more directly and efficiently, this article made a deep analysis of the graphic real-time monitoring technology based on the electric parameter information, the basic frequency component of the electric signal is extracted quickly, which makes the monitoring system have higher real-time performance. At the same time, the information of the electric parameter is scientifically fused by using lissajous graphical method, this makes the recognition technology real-time and graphic. Finally, the identification system is designed with the help of LabView system, and the limit working condition of hydraulic system is taken as the test object to verify the practicability and stability of the development technology, thus provides the innovative development path for the hydraulic system state recognition system.
