With the development of technology, library anti-theft technology is also constantly upgrading. Today, let's take a look at how the modern library security anti-theft system has evolved.
The anti-theft methods of traditional libraries
Electromagnetic induction door: Install an electromagnetic induction door at the entrance of the library, which interacts with the electromagnetic field at the door through electromagnetic tags placed in books. When a reader passes through the electromagnetic induction door with an unreturned book, the door will automatically sound an alarm.
Magnetic stripe anti-theft system: Stick magnetic stripes on books and set up a magnetic stripe detector at the entrance of the library. When readers pass through the detector with unreturned books, the detector will sound an alarm.
RF (Radio Frequency) anti-theft system: Install RF tags in books, and when readers pass through the RF door with unreturned books, the door will automatically sound an alarm.
Current anti-theft methods for smart libraries
RFID (Radio Frequency Identification) anti-theft system:
RFID tags are installed on books, and when readers borrow books, the
RFID tags are scanned. When borrowing or returning books, they need to be identified through
RFID readers, avoiding false alarms or omissions in traditional anti-theft technology.
Camera recognition: Install cameras in the library to recognize the behavior of readers borrowing and returning books through computer vision technology. When a reader is detected passing through the entrance with an unreturned book, the system will automatically sound an alarm.
Artificial Intelligence Recognition: Utilizing artificial intelligence technology to automatically recognize the behavior of readers borrowing and returning books, achieving a more intelligent anti-theft system.
The mainstream anti-theft mode of the library
At present, the most commonly used anti-theft mode in libraries is the
RFID (Radio Frequency Identification) anti-theft system. Its working principle is to install
RFID tags on books. When a book leaves the library without going through the borrowing and returning procedures, the
RFID reader will automatically detect and issue an alarm to remind the administrator to handle it.
Install
RFID high-frequency security doors at the borrowing channel or main entrance of the library. After borrowing and returning the books through a dedicated
RFID librarian workstation, the anti-theft position in the
RFID tag inside the book will be released, allowing normal access to the library. When books that have not gone through normal procedures pass through the security door, an audible and visual alarm will be triggered to remind borrowers to complete the borrowing procedures.
The main advantages of
RFID anti-theft system are:
High efficiency: The
RFID anti-theft system can quickly detect books that have not gone through the borrowing and returning procedures, greatly improving the management efficiency of the library.
Automation:
RFID anti-theft system can achieve automated book borrowing and returning operations, greatly reducing the workload of administrators.
Good anti-theft effect:
RFID anti-theft system can effectively prevent book loss and theft, saving libraries a lot of money and labor costs.
Comparison of anti-theft methods in libraries
Although both RF (Radio Frequency) anti-theft systems and
RFID (Radio Frequency Identification) anti-theft systems use radio frequency technology, their working principles and application scenarios are different. The RF anti-theft system mainly achieves anti-theft by detecting RF signals, while the
RFID anti-theft system achieves anti-theft by binding
RFID tags and reader information.
RFID anti-theft system is more intelligent and accurate than RF anti-theft system, which can reduce false alarms and missed alarms.
Camera recognition, artificial intelligence recognition, and
RFID technology are usually complementary in libraries.
RFID technology can be used for anti-theft, circulation, retrieval, and positioning in libraries, but its application in analyzing readers' needs and behaviors is limited. Therefore, camera recognition and artificial intelligence recognition can serve as supplements to
RFID technology to provide more intelligent and personalized services and management.
