摘要
为提高提升系统的安全性,对液压站的研究具有重大的意义。针对液压泵的运行状态难以监测,引用了利用液压泵的出口压力信号作为液压泵的状态参数,巧妙地加入了小波分析和小波包分解,经过实践与仿真,验证了该方法的可行性与有效性。
In order to improve the safety of the upgrade system,it is of great sigficance to make the research on the hydraulic station.h is a difficult task to monitor the pump condition ,so citing the outlet pressure of the pump as the state parameters,joining the wavelet analysis and wavelet packet decomposition brightly,through the practice and simulation,demonstrated the feasibility and validity.
