Multiple RFID reader system and method for controlling multiple RFID readers in the same
First Claim
1. A method for controlling multiple Radio Frequency Identification (RFID) readers in a multiple RFID reader system, the method comprising:
- registering environment information of an RFID reader when the RFID reader is newly connected to the system;
calculating respective probabilities of radio interference between the newly connected RFID reader and already connected RFID readers;
creating a radio interference logical operation list using the calculated radio interference probabilities;
comparing the created radio interference logical operation list with a list of currently running RFID readers when a request to activate the newly connected RFID reader has been made; and
deciding whether or not to activate the newly connected RFID reader according to the comparison.

Abstract
A multiple RFID reader system for controlling operations of multiple RFID readers is provided. To minimize radio interference between multiple RFID readers, when a new RFID reader connects to the system, the system calculates probabilities of radio interference between the new RFID reader and already connected RFID readers and creates a radio interference logical operation list using the calculated radio interference probabilities. When it has been requested that the new RFID reader be activated, the system compares the created radio interference logical operation list with a list of currently running RFID readers and decides whether or not to activate the new RFID reader based on the comparison.

9. A multiple RFID reader system comprising:
-
a reader environment information manager that registers a new RFID reader when the new RFID reader is connected to the system and manages environment information of already connected RFID readers;
a radio interference probability manager that calculates and manages respective probabilities of radio interference between the new RFID reader and the already connected RFID readers;
a list manager that creates and manages a radio interference logical operation list using the calculated radio interference probabilities; and
a reader connection manager that manages connection of all the connected RFID readers and, when a request to activate the new RFID reader has been made, decides whether or not to activate the new RFID reader by comparing the created radio interference logical operation list with a list of currently running RFID readers. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
