Self-service entrance guard system of university library based on RFID smart card 2022-01-05

The library access control system guarantees the safety of book resources and improves the management efficiency and level of the library. With the support of computer technology, network technology, and target recognition technology, there are currently many library access control systems customized and developed according to different library informatization conditions.  In order to realize the seamless link between the access control system and various digital libraries, expand the functions of the access control system, and improve the self-service level of the library, we have built a set of self-service access control systems for college libraries based on RFID cards.

RFID technology is a non-contact automatic identification technology realized by radio frequency communication.As a wireless version of barcodes, RFID technology has the advantages of waterproof, antimagnetic, high temperature resistance, long service life, long reading distance, data encryption on smart cards, larger data storage capacity, and more free storage of information that are not available in barcodes. It is recognized by the world as one of the ten important technologies of this century. A basic RFID system generally includes the following parts: a smart card that contains information about the target, that is, an RFID smart card, an antenna that transmits RF signals between the reader and the RFID unit, and an RF that receives the return from the RFID smart card. RFID reader that signals and transmits the decoded data to the host system for processing. At present, the RFID system has been used in traffic management, warehouse management, logistics management, production line tracking and other fields.

With its unique characteristics, RFID technology has attracted the attention of libraries at home and abroad. The National Library of Singapore began to use RFID technology in late 1998, becoming the first library in the world to apply this technology. Subsequently, the United States, Australia, China, etc. have also adopted this technology one after another. In 2006, my country's first RFID smart library was completed and put into use, the Chengyi College Library of Jimei University. Many libraries, including the New Shenzhen Library, the National Library, and the Shanghai Changning District Library, have also cited this technology. Based on the above-mentioned library using RFID technology, the functions it realizes roughly include:

  ● Self-service book borrowing and returning system: Provide readers with self-service book borrowing and returning operations without the intervention of library managers;

  ●Book sorting: realize the automatic inventory, arrangement and order of collection materials, so as to achieve the purpose of borrowing and returning;

  ●RFID security detection: For books that have not been checked out or are forbidden to be loaned out, the security check device will alarm when going out to remind the management staff to stop them in time.

Through RFID technology, the library has created huge social benefits for the library industry in terms of effectively improving management accuracy, improving service image, and expanding extended services, and has been recognized by the majority of colleagues.

Smart card is also called integrated circuit card, or IC card, which embeds an integrated circuit chip in a plastic substrate and encapsulates it into the form of a card. In 1977, Motorola cooperated with one of its computer customers to develop the world's first smart card. Since then, smart cards have been widely welcomed for their thin and small size, advanced integrated circuit chip technology, and characteristics that cannot be deciphered or imitated. , And has achieved unprecedented development worldwide. At present, various smart cards are increasingly used in various fields of the national economy and penetrate into the daily lives of residents.

RFID smart card is a non-contact IC card. It has the characteristics of small size, large capacity, long life, reusable, etc. It can support fast reading and writing, non-visual recognition, mobile recognition, multi-target recognition, positioning and long-term tracking management.
