The basic working principle of RFID technology in library is not complicated: After the RFID tag enters the magnetic field, it receives the radio frequency signal from the reader, and uses the energy obtained by the induced current to send out the product information (passive tag) stored in the chip, or the tag actively sends a signal of a certain frequency (active tag), the reader reads and decodes the information, and then sends it to the central information system for relevant data processing.
Nowadays, RFID technology has been applied in all aspects of life, including logistics and supply management, manufacturing and assembly, air baggage handling, mail/express package handling, document tracking/library management and animal identification. Take the library as an example. With the continuous advancement of the times, the consulting culture has become more developed, and the phenomenon of knowledge economy has become increasingly prominent. The library has become an important place for consulting services. On the one hand, large and medium-sized libraries often encounter problems such as theft of books, long queues for borrowing and returning books, and inability to quickly and accurately count books due to the large number of people in and out of the library and the large number of books in the collection. The smart library management system using RFID can solve these problems and realize the following functions:
1. Improve the efficiency of book borrowing and returning
When borrowing and returning books with traditional barcode and magnetic stripe technology, staff still need to open the book's front page to find the barcode, and then scan and demagnetize it. The borrowing and returning efficiency is relatively low. After adopting RFID technology, the RFID smart tag reader reads the rfid tags for books in a non-contact manner, and with the help of the anti-collision function of RFID technology, it can read and identify multiple books at the same time, thereby improving the borrow and return efficiency and reader reception ability.
2. Improve service level of library
With the self-service book borrowing and returning peripheral equipment, readers can find the shelf number of the book in the network system, quickly and accurately find the book they need, and go through the book borrowing and return procedures by themselves, which brings convenience to the reader.
3. Strengthen collection management
In the open-shelf library, library management staff usually need to spend a lot of energy to find books and periodicals that are out of order or the wrong shelves, and sort them out. The workload and work intensity are relatively large. By entering the shelf information of the books into the RFID system, the staff can use the handheld reader to find out the information of the disordered books in time during the daily shelf patrol, thus making the shelf arrangement and the whole shelf work quite easy.
4. Strengthen anti-theft monitoring capabilities
Traditional magnetic stripe anti-theft systems often have many unreal theft situations, such as false alarms and false alarms for unclean degaussing. The RFID access control system can use the integrated handheld reader to determine whether the checked book is illegally entrained or the borrowing record misses the book, and then determines whether to make an alarm action, reducing the rate of false alarms.
