1.INTRODUCTION

Theperformanceandqualityoftheconstructionmachineryhasaveryimportantinfluenceontheconstructionschedule.Butconstructionmachineryhasahigherfailureratebecauseofitscomplexstructure,uncertainloadandpoorworkingenvironment[1].Therefore,thesupervisionoftheconstructionmachinery’sperformanceisastickingpointforthestabilization,safetyandreliabilityofconstructionwork.Withthesocialdevelopmentandtheadvancementoftechnology,peoplehavebecomeincreasinglydemandingontheperformancemonitoringandfaultdiagnosisofconstructionmachineryinordertogetahigherefficiencyandlowerconsumptionofconstructionproject.Thenew-generationconstructionmachinerynotonlyneedintegratingoperationandintelligentcontrol,butalsoneedcooperatingwiththewholeconstructionmachinerygroupwhosecontrolsystemisbasedonnetwork.Atpresent,thetraditionalconstructionmachinerywhichisonlydesignedbygeneralelectroniccontroltechniquesanditstraditionalregularmaintenancecannotmeettherequirements.Soanewconstructionmachinerymonitoringsystem,whichcanfinishthelocalcentralizedcontrol,supervisionandmaintenance,andcanalsocarryoutremote-distancemonitoranddiagnose,hasbecomeahotresearchproblem[2]-[5].
