further, the first time may be, but is not limited to, 500ms to 3 s.
And a second scanning mode is adopted, so that the repeated and cyclic scanning of the RFID tags 16 with moderate quantity is suitable, the scanning is stopped for 500ms to 3s after all the RFID tags 16 in the storage space are scanned once, and then all the RFID tags 16 are scanned next time according to the original scanning sequence, so that a worker can know the scanning times and distinguish the scanning times between the previous scanning and the next scanning, the quantity of the RFID tags 16 after each scanning can be determined, and the issuing quantity of the medical supplies and which medical supplies are issued can be further known.
And a third scanning mode: if the number of the RFID tags 16 is within the third number (the number of the RFID tags 16 is greater than 500), the RFID reader 17 is controlled to scan each RFID tag 16 in sequence only once, or the RFID reader 17 is controlled to be powered off after the previous scanning of each RFID tag 16 is completed, and the power is supplied to the RFID reader 17 after the second time of pause for the next scanning.
Further, the second time may be, but is not limited to, 3s to 60 s.
And the scanning mode III is adopted, so that the method is suitable for scanning a large number of RFID labels 16. Because the number of the RFID tags 16 is large, in order to improve the working efficiency and ensure that each RFID tag 16 is scanned, each RFID tag 16 is scanned once and compared with the number of the original RFID tags 16 in the storage space, so that the issuing number of the medical supplies and which medical supply is issued are determined; if each RFID tag 16 is repeatedly scanned when the time is allowed, the RFID reader 17 needs to be powered off, and power is supplied to the RFID reader 17 again after the power is turned off for 3s to 60s, so that the RFID reader 17 can scan each RFID tag 16 again.
The scanning method of the RFID label has the characteristics and advantages that:
according to the scanning method of the RFID tag, different scanning modes can be selected according to the number of the medical supplies in different storage spaces, the reading accuracy and the reading number of the RFID tag 16 are guaranteed, meanwhile, the reading efficiency of the RFID tag 16 is greatly improved, and further the sequential issuing and accurate tracing of the medical supplies are guaranteed.
The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes and modifications that can be made by one skilled in the art without departing from the spirit and principles of the invention should fall within the protection scope of the invention.
