基于LabVIEW的工作面输送设备远程监测与诊断系统设计

摘要

In view of problem that current monitoring and diagnosis systems of conveying equipments on working face can be only used at underground field, a remote monitoring and diagnosis system of conveying equipments based on LabVIEW in surface dispatching center was designed. General structure of monitoring and diagnosis system of conveying equipments of whole mine manless working face composed of the system and underground monitoring and fault diagnosis system of conveying equipments based on PLC was given, implementation of data exchange between the system and the underground system was analyzed, and method of BP neural network fault identification in LabVIEW and design of SQL Server data management system were introduced. The actual application shows that the system runs stably and realizes real-time monitoring and diagnosis of conditions of scraper conveyor, transfer conveyor and crusher on working face in surface dispatching center.%针对现有工作面输送设备监测与诊断系统只能在井下现场使用的问题,设计了一种基于LabVIEW的安装于地面调度中心的输送设备远程监测与诊断系统；给出了由该系统与井下基于PLC的输送设备监测与诊断系统相结合构成的全矿井无人工作面输送设备监测与诊断系统的整体结构,分析了该系统与井下系统间的数据交换实现,介绍了在LabVIEW中运行BP神经网络故障识别的方法及SQL Server数据管理系统的设计.实际应用表明,该系统运行稳定,实现了在地面调度中心实时监测和综合诊断工作面刮板输送机、转载机和破碎机的工况.
