Design of Fault Monitoring System of Mine Drainage Device Based on LabVIEW

Abstract

In view of problems of rotor eccentricity, high temperature, excess vibration and blocking of drain-pipe in motors of traditional drainage devices of coal mine, a fault monitoring system of mine drainage device based on LabVIEW was designed. The system uses LabVIEW software and data acquisition card to collect data such as pipe flow, pipe pressure, vacuum degree of water pump and temperature and vibration of motor of the mine drainage device, and makes domain analysis, amplitude spectrum analysis and fault diagnosis of vibration signals, so as to realize early warning for over-limit signals.
