| description | The invention discloses a monitoring method and a monitoring system for vibration of a water-pumping energy-storing set. The method comprises the steps of acquiring a vibration displacement signal and a vibration speed signal of the water-pumping energy-storing set in an upper frame triaxial direction, a lower frame triaxial direction, a stator middle-part horizontal direction, a stator upper-part vertical direction and a top-cover triaxial direction, and then performing calculation for acquiring a vibration displacement time domain parameter, a vibration displacement frequency domain parameter, a vibration speed time domain parameter and a vibration speed frequency domain parameter; and obtaining a vibration characteristic parameter P according to the parameters. The monitoring system comprises a computer (1) and a data acquisition card (2). The data acquisition card (2) is connected with 11 displacement type low-frequency speed sensors (5) and 11 speed type low-frequency speed sensors (6) through a first si |
