TAG DATA FILTERING DEVICE IN AN RFID MIDDLEWARE CAPABLE FILTERING TAG DATA AT HIGH SPEED

摘要

PURPOSE: A tag data filtering device in an RFID middleware is provided to reduce the number of pattern matching in order to filter tag data in an RFID middleware.;CONSTITUTION: A tag group(100) stores an RFID code and related information. A plurality of readers transmits tag data in a middleware(300). The middleware transmits tag data to a host(400) after filtering tag data. The middleware configures a pattern tree through a query analysis of the host. The middleware designates a pattern field, in which a merge pattern and an including pattern is overlapped, as a fail node.;COPYRIGHT KIPO 2011
