Centralized Vibration Monitoring and Analysis System

Abstract

All mechanical equipment in motion generates a vibration profile, or signature, that reflects its operating condition. This is true regardless of speed or whether the mode of operation is rotation, reciprocation, or linear motion. Vibration analysis is applicable to all mechanical rotating machinery and is a useful tool for predictive maintenance, diagnostics, and many other uses. Predictive maintenance has become synonymous with monitoring vibration characteristics of rotating machinery to detect budding problems and to head off catastrophic failure. Current scenario in the industries is that vibration monitoring data are measured along with plant parameter. But this vibration monitoring data are used for only safety purpose or HMI (Human Machine Interface) purpose. So the goal of the project is to develop such a cost effective system which can easily performs Vibration analysis, Predictive maintenance and Comparative analysis of any rotating machinery to detect vibration fault. The system has developed in LabVIEW. Vibration analysis contains time domain and frequency domain analysis. Predictive maintenance contains failure mode analysis based upon peak generated in Fast Fourier Transforms of vibration signal. Comparative analysis compares two vibration values to generate different alarm.
