| description | The invention provides a state monitoring device provided with a provided with machine pump online energy efficiency evaluation function. An energy efficiency module is arranged in a CMS acquisition host machine; after sensor data is acquired and energy efficiency is analyzed, real-time energy efficiency analysis results are sent to a software system; after performing HILBERT transform, rotation speed order analysis and FFT analysis on a filtered signal, a fault diagnosis module extracts energy amplitude which corresponds to each anomalous characteristic ratio, compares energy percentage of each anomalous characteristic point with a threshold value, and performs fault alarm while each anomalous characteristic point exceeds the threshold value. The state monitoring device calculates energyconsumption and an efficiency state of a motor, a water pump and a unit in real time through an energy efficiency analysis module of the state monitoring device, so that energy consumption analysis data and fault diagnosis da |
