CONTROL OF LARGE NUMBER OF RFID-TAGS IN CRYOGENIC CONTAINER Russian patent published in 2021 - IPC G06Q10/08 G06K7/10 

FIELD: radio communication.

SUBSTANCE: invention relates to the use of tags of radio frequency identification in containers. A method for identifying a large number of tags of radio frequency identification in a container is disclosed, while the number of tags of radio frequency identification is at least 100 in a cryogenic container, wherein the method provides for stages of: configuring a request block of radio frequency identification connected to a set of antennas for a request to transmit radio frequency signals of the request in a container with a frequency of at least 30 MHz; configuring a request block of radio frequency identification to operate in a set of different modes of signal distribution by applying a radiation pattern, so that the container is divided into a set of distribution zones, wherein each distribution zone is associated with the corresponding distribution mode, while antennas for the request are made with the possibility of using separate radiation pattern lobes associated with distribution zones, and to operate with individual weighting gain factors in such a way that only tags of radio frequency identification are activated in a certain distribution zone, when the request block is in the corresponding distribution mode; and configuring a request block of radio frequency identification to receive radio frequency signals of a response from tags of radio frequency identification.

EFFECT: ensuring the identification of tags of radio frequency identification in the container.
