Rapid maintenance device, method and equipment based on RFID tag repeater

The invention discloses a rapid maintenance device, method and equipment based on an RFID tag repeater, and belongs to the technical field of Internet of Things. The device comprises a relay reading module which is arranged at a preset position of a target area and interacts with each RFID tag in the target area so as to acquire data information of each RFID tag; the storage module associates the identity information of each RFID tag with the sent data information and stores the identity information and the sent data information in a data storage area; the instruction receiving module is used for receiving a data reading instruction sent by the reader-writer; and the data feedback module is used for feeding back the identity information of the associated and stored RFID tag and the corresponding data information to the reader-writer. According to the scheme, through interaction with the RFID tag, data can be automatically acquired, the efficiency and accuracy of data acquisition are improved, and the labor co
