Research on middlerware of equipment management EPC system

The radio frequency identification and the components of electronic product code (EPC) system which it is usually used in are introduced. To resolve the problem of processing out-of-core data produced in the equipment management EPC system, a data filter method is designed, which based on the event status change. And the middleware with reference to savant specification 1.0 is designed to remove redundancies and only report status changes of tags to upper layer application. At last combined with the upper layer application, the performance of the method is discussed.
