Description

technical field [0001] The invention relates to the technical field of communication, in particular to an RFID reader-writer based on UHF technology and a control system thereof. Background technique [0002] The RFID reader is a radio frequency identification device that automatically identifies the target object and obtains relevant data through the radio frequency identification signal. It is widely used in logistics and warehousing management, anti-counterfeiting traceability, industrial manufacturing, animal husbandry and other fields. The RFID reader communicates wirelessly with the RFID electronic tag through the antenna, and can realize the reading or writing operation of the memory data of the tag identification code. The RFID reader mainly includes an RFID radio frequency module, a control unit, and a reader antenna. The radio frequency module includes a transmitter and a receiver. The contactless coupling of the radio frequency signal is realized through the coup...
