【摘要】 大型水泵机组是常见旋转机械设备,采用的检测方法和装置是点检制度,用状态监测系统(含数据采集系统)进行巡检,发现故障征兆后再重点监测和精确诊断。介绍了虚拟系统实现智能监测与远程通信方法的特点。针对机组为关键机械,采用了实时的在线监测和故障诊断系统。采用离散小波变换对振动信号进行处理,对压力、温度、电量等其它参量进行联检与分析,用LabVIEW系统进行归纳、对比,采用DataSocket方式实现远程通信。更多还原

【Abstract】 The Large-scale Water Pump Set is the ordinary rotation machinery, using the point’s examined method and making check around with the monitoring system (include the datum collection system). When the prime examine find the wrong, the emphasis checking and the diagnosis can be used. The paper introduces the intelligent monitor and the tel-communication based on virtual system. Because the pump set is the importance machinery, real-rime and on-line examining is used. Discrete Wavelet Transform is used to deal with the vibration signal,but the force, temperature and electroform data are collected. Integrated these data, the fault diagnosis can be realized. Used the DataSocket protocol, the project can achieve the remote communication.更多还原
