The system works with near-field radio frequency tags of the ISO 18000-63 standard.
]]>The desktop reader is a monoblock with a built-in antenna that is connected to a personal computer via a standard interface cable.
]]>During the rejection of RFID tags, the numerator allows double checking of tags-in the near and far field. Defective RFID tags are either marked or removed from the tape. Numbered RFID tags are rolled up.
]]>Using the station reduces the time that library staff spend on routine operations, reduces queues, and improves the quality of reader service. Now librarians will be able to devote more time to scientific work, as well as help in finding and selecting literature for readers.
]]>The built-in RFID reader antenna is a patch – type, two-element phased array that provides an asymmetric directional pattern to overlap the width of the passageway in the transverse direction and while reducing the radiation in the direction of the passageway, which reduces the possible spurious registration of RFID tags outside the control zone.
The ceiling RFID reader is mounted above the registration area in a suitable way (racks, suspension on cables) with the working side facing down to the control area (the long side of the case along the aisle). The effective registration zone is a cone-shaped area under the antenna.
The size of the registration zone depends on the design of the RFID tags used, the installed capacity of the reader, and the physical properties of third-party objects located near the registration zone, and is determined experimentally in each case. Note that the length of the registration zone along the long side of the antenna is approximately half as long as the length of the registration zone along the short side of the antenna. The most effective registration of a radio frequency RFID tag occurs when it is located directly under the antenna.
]]>Main components of the reader unit:
The RFID reader works independently or under the control of external software. Autonomous operation of the RFID reader is used in the library system when the read data of the RFID tag is used to allow the movement of the RFID tag and to send an alarm. When working under the control of external software, communication with the reader is performed over an Ethernet network, the LLRP Protocol.
The reader stands are attached to the floor using anchors.
