Title: Systems and methods for managing a population of RFID tags
Inventor: DAVID BELLOWS
IPC: G06Q10/08
Filed: 2019-11-12
Abstract: Radio frequency identification (RFID) reader system, comprising: a RFID detector stations (30, Fig. 1) configured to implement one or more RFID protocols; and RFID tags (12, Fig. 1) configured with a selection flag. The RFID tag only responds to a query when the protocol and selection indicator match. A first query is broadcast 606 using a first protocol. Tags utilising the first protocol change to another protocol for a duration then return to the first protocol. Upon detecting responses 608, second and a third protocols 610 are broadcast to change RFID tag protocols to a second or third state and set selection flags. Tags remain in this state until: queried by an RFID reader using the same protocols; or until the RFID tag loses power. Hence, an RFID tag responding to a query alternates between the first and second protocols. The detector stations may form an alternating pattern of protocols (checkerboard, Fig. 4). RFID readers may be: a plurality of radially distributed antennas; or a phased antenna array forming a plurality of radially distributed virtual antennas. If the responses exceed the system’s maximum threshold one or more tags may be deselection for response by altering the tags’ selection status indicator.
