Rfid Reader Interface and Event Management Apparatus for Supporting Multi-Protocol-Based Heterogeneous Readers and Method Therefor
First Claim
1. A Radio Frequency Identification (RFID) reader interface apparatus for multi-protocol based heterogeneous reader support for providing an interface between RFID readers and application systems, the apparatus comprising:
- a reader connection management means for identifying a plurality of RFID readers separately and establishing a connection between the RFID readers and the application systems;
a reader transmission/reception process means for receiving tag data from the RFID readers or sending application system data to be converted into individual protocol data at a protocol process means to the corresponding RFID readers;
the protocol process means for converting the tag data received by the reader transmission/reception process means into common protocol data or application system data received by a middleware transmission/reception process means into the individual protocol data, to support the heterogeneous RFID readers; and
the middleware transmission/reception process means for sending the tag data converted into the common protocol data at the protocol process means to the application systems or an RFID event management device, or receiving the application system data from the application systems.

Abstract
Provided are a Radio Frequency Identification (RFID) reader interface supporting multiprotocol-based heterogeneous readers, and an event management apparatus and method therefor. The interface supports communication between heterogeneous readers and application systems, and remarkably reduces the amount of data to be sent to the application systems through event generation and data filtering. The interface includes: a reader connection management unit for and establishing connection between the RFID readers and the application systems; a reader transmission/reception processor for receiving tag data from the RFID readers or sending application system data to be converted into individual protocol data; the protocol processor for converting the tag data into the individual protocol data to support the heterogeneous RFID readers; and the middleware transmission/reception processor for sending the tag data converted into the common protocol data to the application systems or an RFID event management device, or receiving the application system data from the application systems.

24. An RFID reader interface method for multi-protocol based heterogeneous reader support for providing an interface between RFID readers and application systems, the method comprising the steps of:
-
a) identifying a plurality of RFID readers separately, giving a reader identifier to each RFID reader, and establishing a connection between the RFID readers and the application systems using the reader identifiers;
b) after the connection is established at the step a), receiving tag data from the RFID readers or sending application system data to be converted into individual protocol data at step c) below to the RFID readers;
c) converting the tag data created in accordance with individual protocol every RFID reader into common protocol data or application system data prepared in accordance with common protocol into the individual protocol data, to support the heterogeneous RFID readers; and
d) after the connection is established at the step a), sending the tag data converted into the common protocol data at the step c) to the application systems or an RFID event management device, or receiving the application system data from the application systems. - View Dependent Claims (25, 26, 27)
