基于LabVIEW的淮安一站水泵机组振动监测系统设计与开发

Design and development of vibration monitoring system for Huai′an No.1 Station pump unit based on LabVIEW

为实现淮安一站水泵机组的智能化运行状态监测,基于LabVIEW虚拟仪器开发软件,研发了一套集数据采集、三维显示、信号分析、状态推送、故障预警为一体的智能化振动监测系统.采用“生产者—消费者”模型作为程序设计的主体结构,其中“生产者”循环对实时采集的数据进行队列缓存,“消费者”循环通过出队操作获取缓存数据供后续处理.该系统主要实现了:水泵机组重要运行状态参数的采集、显示、分析;动态联查水泵机组的运行状态参数;水泵机组监测点处振动信号的时频域分析;调用Python的企业微信脚本向泵站管理人员推送水泵机组运行状态;设定水泵机组振动阈值进行自动故障预警.通过淮安一站水泵机组的试验测试发现,所开发的智能化振动监测系统不但实现了预期开发目标,而且具有开发成本低廉、人机交互界面友好、可移植性较强、后期维护方便等优点.

In order to realize the intelligent operation state monitoring of the pump unit in Huai′an No.1 Station,an intelligent vibration monitoring system integrating data acquisition,3D display,signal analysis,state push,and fault warning was developed based on LabVIEW virtual instrument development software.The″producer-consumer″model was utilized as the main structure of the program design.The″producer″cycle implemented the queue cache of the data collected in real-time,and the″consumer″cycle obtained the cached data through the dequeuing operation for subsequent processing.The system mainly realized the collection,display,and analysis of important operating state parameters of the pump unit.Operating state parameters of the water pump unit were inspected dynamically and jointly.Time-frequency domain of vibration signals at monitoring points of the water pump unit was analyzed.The Python WeChat script was called to push the running status of the pump unit to the pump station manager.The vibration threshold of the water pump unit was set for automatic fault warning.Through the test of the pump unit in Huai′an No.1 Station,it is found that the intelligent vibration monitoring system developed monitoring system achieves the expected development goals,and has the advantages of low development cost,friendly human-computer interaction interface,strong portability,and convenient maintenance in the later period.
