基于LabVIEW的矿井排水装置故障监测系统的设计

摘要

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.%针对传统的矿井排水装置中电动机易发生转子偏心、温度过高、振动过大、排水管道堵塞等问题,设计了一种基于LabVIEW的矿井排水装置故障监测系统.该系统能够通过LabVIEW及数据采集卡对排水装置的管道流量、管道压力、水泵真空度、电动机温度、电动机振动等数据进行采集,对振动信号等进行时域分析、幅值谱分析及故障诊断,从而实现对各种超限信号的有效预警.
