Design of Remote Monitoring and Diagnosis System of Conveying Equipments on Working Face Based on LabVIEW

Abstract

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.
