I.INTRODUCTION

Withthedevelopmentofthemoderntechnology,avarietyofrotatingmachinery（suchassteamturbine,fan,windturbine,etc.）raisesthelevelofautomaticoperation.Duetothesignificantrolesoftherotatingmachineryinthemodernproductionprocess,toensurethesafety,reliability,economicalandoptimizedoperation,andtoevaluationofthe

Thedatabasetechnologyandnetworktechnologywereintroducedinthecurrentonlinemonitorandfaultdiagnosissystemforrotatingmachinery.Itnotonlyenhancedthetechnologyofonlineconditionmonitorandprovidedmoresufficientandreliabledataforthefaultdiagnosis,butalso

However,fortherequirementsofequipmentmanagementnowadays,thecurrentnetwork-basedonlinemonitoringsystemremainssomedefectsasfollows:
