【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】 Large-scale water pump set is the common rotation machinery using the spot check method and making check tour with the monitoring system (including the data-collection system). When the prime examination finds sign of fault,focal check and diagnosis can be used. Intelligent monitor and the tele-communication based on virtual system are introduced.As the pump set is the key machinery, real-time and on-line examining is used in monitoring and diagnosis. Discrete Wavelet Transform is applied to deal with the vibration signal,and the force, temperature and electroform data are collected. Integrating these data, fault diagnosis can be realized.Based on the DataSocket protocol, the project can achieve the remote communication.更多还原
