RFID MIDDLEWARE SYSTEM AND METHOD TO SUPPORT REAL-TIME BALANCING LOAD OF READER CONNECTIONS

摘要

PURPOSE: An RFID(Radio Frequency IDentification) middleware system for supporting real-time balancing load of reader connections and a method thereof are provided to minimize the lowering of performance happening when plural readers are connected to each other by detecting and distributing the reader connection load in real time. CONSTITUTION: A middleware engine filters a tag event collected according to a query, and a reader framework detects RFID(Radio Frequency IDentification) reader connection load which happens while driving a middleware in an RFID middleware. The reader frame work includes an adaptor manager(221), an adaptor(222) which converts tag data into a tag event and communicates with the RFID reader, and a load diagnostic unit(223).
