STORAGE DEVICE AND FREEZER

WIPO Patent Application WO/2021/097835

A1

The present application relates to a storage device, comprising a cabinet, storage partitions, RFID modules, a control unit and a plurality of antennas. The cabinet is used to place items carrying corresponding RFID tags. The cabinet comprises a bottom plate. The storage partitions are located in the cabinet and are used to separate the items. The antennas are disposed on the storage partitions and the bottom plate, respectively. Both the RFID modules and the control unit are located on the cabinet. The RFID modules are communicatively connected to the antennas. The control unit is communicatively connected to the RFID modules. The control unit is used to control the RFID modules to drive the antennas to work concurrently at different frequencies, so that the antennas respectively traverse set frequency bands to scan the RFID tags, and item information corresponding to the items is collected. The antennas are reasonably arranged on the storage partitions and the bottom plate in the storage device, and the control unit controls the RFID modules to drive the plurality of antennas to work concurrently at different frequencies, so that the scanning efficiency of the antennas in the storage device is greatly improved.
