On the RFID technology applications in the University Library

Paper Keywords: RFID tag University Library

Abstract: RFID tags commonly known, is a non-contact automatic identification Technology is currently promote the use of University Library The library is currently widely used Technology and bar code systems, has significant functional advantages of the article on RFID Technology and Applications in the library were introduced, and in the Application process problems were analyzed.


RFID (Radio Frequency Identification, referred to as RFID), commonly known as RFID, is a non-contact automatic identification Technology, which automatically identifies the target by radio signals, you can quickly track of items and data exchange, to identify fast moving objects can also identify multiple tags.

RFID is a simple wireless system consisting of a reader (interrogator) many of the tags (transponders) and the antenna transmission signal composed of its working principle is not complicated: label into the magnetic field, issued by the RF receiver readers signal, the use of induced current obtained by sending out the energy stored in the chip information reader to read and decode the information, sent to a central system for the data processing.

Late 20th century, began to RFID to foreign libraries. 2006, Shenzhen became the first library to use RFID Technology to libraries. Up to now, domestic use of library RFID system is close to one hundred, but about 2 / 3 for public libraries, university libraries less than 1 / 3, in Beijing only Beijing University of Technology, Beijing Institute of Petrochemical Technology, Beijing University of Agriculture and so few colleges and universities.


1RFID technology in library management Application

RFID is actually an electronic bar code, and libraries are currently widely used bar code system compared to, RFID systems can not completely replace the bar code system, but also has a more significant feature advantages.

1.1 Self-Borrow
Use bar code system, the reader circulation books must be handmade by the librarian of a local scan a bar code books, while books with RFID self-service circulation systems, RFID chips can read more information, readers should borrow only to All books on self-service circulation machine, follow the prompts, you can complete on their own books to borrow and return, no longer need to manually one by one by the librarian. librarians to reduce the amount of manual labor and improve efficiency.

In particular, when the reader to return books without having to open the library by closing time constraints, you can at any time, any place (self-service system can also book through the network settings in the dormitory, classrooms, cafeteria, etc. anywhere) self-service, easy, fast .

1.2 Book inventory
Bar code reader must be close to identifying bar code, so the inventory of literature will need to remove every book from the shelves, and open, and then swept into the bar by the back, a heavy workload. Portable point inspection equipment using RFID , one can read multiple RFID tag information, simply use the wand on the shelves swept 1-2 times, you can read all the books data, inventory time is shortened, it will not only greatly reduce the labor intensity of staff improve work efficiency, and inventory collection can become a regular work to improve the management level.

Now that the reading room to use more open access approach, the book Disorder is more serious if the book in the wrong place, it is difficult is to find out. The use of RFID technology, you can simply type in the RFID reader in the book-related information, followed by scanning along the shelves, will soon be finding the target, making the work becomes very easy to find.

1.3 in the security management Application security
RFID anti-theft detection system has identified distance, identification speed, low false alarm rate, etc., make up the existence of blind spots and magnetic detection equipment unstable defects, but because of the hidden nature of RFID tags is not good, once even with the torn page out, security features will be lost, so can the RFID reader with the traditional magnetic stripe testing equipment together, two-pronged approach can greatly enhance the reliability of detection system.

2 main Applications

RFID label converting systems: label switching system's main role is to read and write RFID tags, encoding and distribution. RFID tags in stores to identify and track the information necessary to collections, including the book number, book name, search number, belongs to bookshelf information, borrower information, loan dates and other information.

Portable RFID point inspection equipment: shelves posted by scanning RFID tags in circulation data, to achieve the wrong frame inspection, along racks, shelving, bookshelf, remove and read the statistics, data acquisition and processing functions.

Self-Borrow system: can the flow of RFID labels to scan the literature to identify and circulation processing equipment systems for self-help literature for the reader circulation of operation, printable loan receipt and obtain a receipt, simple operation, can be 24 hours.

Security detection system: When the reader access to the library through the system. If books are missing handle, the system will automatically send reminders, and can detect multiple tags, low false alarm rate.

There are also automatic accreditation system, closed system, self-help books also, 24-hour outdoor book return system, and automatic sorting systems, automated onboard systems and other equipment, the user can be optional according to their needs.


3RFID technology problems

3.1 is not uniform technical standards
RFID technology used in the library, according to the application frequency is divided into two technical schools, that is, high frequency (HF) and ultra-high frequency (UHF). These two technology works is not the same, results from the application point of view, is the There are pros and cons of high frequency technology is relatively mature, international standards, improvement, equipment manufacturers and more domestic manufacturers have a representative on the Haiafadi and Shenzhen Haiheng, UHF technology hidden in the label and price advantage, promising future, the domestic manufacturers in Shenzhen representative Invengo.

Different technical standards so that users in the selection process, often difficult choices, once you choose one, it means giving up another, because the tags and readers are not compatible, can not be shared. Between different standard library, difficult for interlibrary loan, data exchange, among others.

3.2 Application of high cost
With the promotion of RFID technology and product localization, RFID products, prices continued to fall, a price tag has grown from fifty-six years ago to the current one dollar a dollar renminbi, but the basic amount in millions of books University Library more than books, this is still a small number, in addition to the above system equipment, you need to start two to three hundred million, if not the support of special funds, the majority of university libraries can not afford.

3.3 traditional ideas
Who has a long history, the Library has managed a team of experienced management personnel, experience is often accompanied by deep-rooted traditional values, their layout on the shelves, books and books arranged in the flow of the program has its own norms and customs , which are difficult to standardize the RFID system fully demonstrated its functional advantages. a short time, which is difficult to change reality.

Any new technology and the popularization will not be easy, RFID is the same, but should believe, RFID technology represents the future trend, with the continuous development and improvement, it will eventually be widely accepted by university libraries. In the modern information technology, driven by the traditional library management system and services are undergoing great change, is the electronic, digital, virtual direction, we must emancipate our minds, a positive acceptance and use of modern information technology to continuously improve service quality of work and work, to better serve the readers. RFID technology would make the overall level of university library board to a new level.
