Design of Pump Station Operation Condition Monitoring System Based on MATLAB Simulation

Abstract

In this paper, through analysis of pump station operation status monitoring system, on the basis of applying wavelet packet analysis to signals processing, MATLAB was used to simulate the design of pump station operation status monitoring system. In the simulation link, through the wavelet packet decomposition and reconstruction of the collected original signal and fault signal of the pump station rotor, fault signal can be judged by comparing and analysing the characteristic vector, power spectrum and energy spectrum of the wavelet packet node. Real-time monitoring of running status of pump station unit rotor was realized, and a simple human-computer interaction interface was designed using MATLAB/GUI (Graphical User Interface), which is simple and convenient to operate. In the human-computer interaction system, the user can observe some characteristic values and spectrum of the rotor signal of the pump station through the drop-down menu, so as to quickly find the fault signal and realize real-time monitoring.
