Radio frequency identification (RFID) is a non-contact automatic identification technology. Different from the traditional way that bar codes rely on photoelectric effect, RFID tags can automatically send the contained information to readers through reading induction without manual operation, thus realizing the automation of book information processing. RFID can automatically read the contents of labels and highly integrate data, so it can record more information about goods. The reading and writing function supported by RFID can play a greater role in book circulation. After using RFID, the library can realize the integration of collection, borrowing and reading of books.
1, the application of RFID technology in library automation management
The Application of 1. 1 in Book Lending and Returning
At present, in addition to optical bar codes as identification codes, library documents are also affixed with magnetic strips for safety reasons to prevent documents from being taken out without authorization. After the application of RFID technology, RFID tags can replace bar codes and magnetic strips, and borrowing books can avoid the trouble of demagnetization and magnetization.
Because RFID technology is a non-contact automatic identification technology, it does not need manual operation when borrowing and returning books, but uses wireless frequency communication for automatic identification, tracking and management. After using this system, as long as readers put their library cards and documents under the borrowing equipment, the RFID borrowing system will automatically scan and identify readers' personal information and document label information. After the borrowing process is completed, the printer will automatically print out the borrowing list, which will be kept by the reader. When returning, the reader sends the document to the recycling equipment, and the RFID reader installed in the equipment can automatically scan and record the book label. The documents are sent to the recycling car by conveyor belt, and then put on the shelf to borrow again.
The Application of 1.2 in Book Inventory Operation
Because the bar code readers must be close to each other, and there is no object to distinguish the bar code, it is necessary to take every book off the shelf when counting. RFID tags transmit signals through radio waves, and the data of multiple RFID tags can be read at one time, which simplifies the inventory work.
The Application of 1.3 in Book Inventory
Using radio wave sensing equipment, it is easy to find books. All books and materials can be read only by sweeping the bookshelf with a hand-held reader, and the inventory time will be greatly shortened.
Application of 1.4 in security and anti-theft management
The access control system of RFID radio wave anti-theft detection has EAS (Electronic Anti-theft) function and integrates RFID reader, which makes the library anti-theft system easier to handle. The collection taken out of the library without authorization will automatically report to the police. In addition to alarm, the camera system will also be triggered; This also avoids the disadvantage that books cannot be detected when they are taken out of the library because of the blind area of magnetic stripe detection equipment.
