Problems solved by technology

[0002] At present, most of the items on the shelves, such as books, archives, medicines, and clothing, are densely placed using RFID technology. The items with RFID tags are usually counted manually through RFID inventory equipment. The RFID inventory equipment currently in use has only one frequency band reader-writer, either can only identify high-frequency tags, or can only identify UHF tags
In the face of the large number of tags of such densely placed items, it is particularly important to improve inventory efficiency, especially for industries such as books and archives management. Books or access to archival materials can cause unnecessary trouble and additional search time

Abstract

The invention discloses an RFID dual-frequency near-field middle-distance reading and writing system, which belongs to the technical field of RFID. It includes ARM core board, high-frequency reader, UHF reader, host computer, power supply circuit, voltage regulator module, communication port and embedded communication and control software. The host computer sends read and write commands through serial port or Bluetooth, The ARM core board receives instructions through the serial port, and selects the reader communication serial port of the corresponding frequency band according to the obtained instructions, so as to realize the switching between the high-frequency reader and the UHF reader, so as to facilitate the reading of RFID tags in different frequency bands , which facilitates subsequent system processing.

Description

technical field [0001] The invention belongs to the technical field of RFID, in particular to an RFID dual-frequency near-field middle-distance reading and writing system. Background technique [0002] At present, most of the items on the shelves, such as books, archives, medicines, and clothing, are densely placed using RFID technology. The items with RFID tags are usually counted manually through RFID inventory equipment. The RFID inventory equipment currently in use has only one frequency band reader-writer, either can only recognize high-frequency tags, or can only recognize UHF tags. In the face of the large number of tags of such densely placed items, it is particularly important to improve inventory efficiency, especially for industries such as books and archives management. Books or access to archival materials can cause unnecessary trouble and additional search time. Contents of the invention [0003] In order to solve the defects existing in the prior art, the ...
