The Study On Vehicle Condition Based Maintenance Diagnostic System Using RFID

The mode of vehicle maintenance is based on the fault which has happened atpresent, this kind of maintenance mode costs more money and takes longer time. Butcondition based maintenance can identify and judge the faults in time, eliminate thehidden danger or repair faults bef’ore big losses, whats more, it can ensure trafficsafety.This paper developed a vehicle condition based maintenance diagnostic systemusing RFID, the system is composed by an information system based on RFID, avehicle failure prediction system based on BP neural network and a vehicle failurediagnostic system. And the system can determine the vehicle’s failures or the failuresthat might occur in the future according to the state parameters of the vehicle.Wh’ats more, it can also give maintenance recommendations according to the faultphenomenon or fault position. Combining with RFID (radio frequency identification)techno logy can ensure the maintenance, repair, and other data in vehicle life cycleavailability with the greatest degree, which satisfies the needs of vehiclemaintenance companies.Firstly, this paper analyzed the key development points of RFID system andvehicle condition based maintenance diagnostic system. The RFID informationsystem development points included the design of the RFID t’ags memory usage andth’e design of the RFID middlewares communication protocol; the developmentpoints of vehicle condition based maintenance part included the data process, thechoice of vehicle fault prediction methods and the choice of vehicle fault diagnostic’methods, whats more, after the comparison of5vehicle fault prediction methods and3vehicle fault diagnostic methods, BP neural network was chosen as the vehicle faultprediction method, expert system was chosen as the vehicle fault diagnostic method.After that, this paper designed and developed the RFID information system, thevehicle failure prediction system based on BP neural network and the vehicle failurediagnostic system separately, and the testing result of the three systems indicatedthat all the systems worked well.At last, this paper did integrating design for the vehicle condition basedmaintenance diagnostic system using RFID, developed the database by SQLS—erver，and the testing result indicated that the vehicle condition based maintenancediagnostic system using RFID worked well.
