1.1 Project background
According to research and analysis, there are currently over 10,000 libraries nationwide, and most libraries have transitioned from a purely manual management mode to a digital management mode that uses barcode recognition, computer networks, and computer software technology. The use of the Internet of Things RFID technology to build an intelligent book management system has become the focus of the needs of various libraries.
1.2 Project demand analysis
According to the current library, the book use, borrowing, and return process will all have contact with the book. However, the book will use barcode technology as identification. However, the continuous use and borrowing process of the barcode makes the barcode easy to wear, and the storage space is small. It is inconvenient to use inside the pasted book, and the outside of the pasted book is easy to wear out quickly. This is not entirely suitable for libraries and is used by large crowds.
1.3 Advantages of RFID technology application
By associating the barcode of the book with the electronic label, the association management of the book is realized. The electronic label can be placed in the book by using self-adhesive or chip built-in method. Readers can borrow and return independently through the automatic borrowing and returning cabinet. The administrator can use the counting machine to regularly check the books in the library, and it can also find the shelves and so on. Features. Equipped with a security door with UHF reader, it can realize the collection of data in and out of books to prevent illegal loss of books.
The RFID technology used in the library mainly focuses on the RFID technology in the HF and UHF frequency bands, which can be applied to related carriers in the library to meet other application requirements.
1.4 RFID book management planning
The hardware of the RFID book management system includes radio frequency acquisition equipment, automatic borrowing and returning equipment, database servers, switches, and security door detection. These devices use RS-485, Ethernet or GPRS transmission interfaces in the switch to effectively integrate various devices and serve together Library management system.
1.5 Management planning of library management system
1.5.1 Network architecture diagram
1.5.2 System management function planning
According to the different business needs of the library, our company plans the system into basic data maintenance, book borrowing management, new book ordering management, book statistics management, RFID management, system setting and other modules.
1.5.3 Function description
1.5.3.1 Basic data maintenance
Basic data maintenance is mainly for the management and query of reader information, book information, and book category.
1.5.3.2 Book Borrowing Management
The book lending system is mainly aimed at the effective management of the business of borrowing and returning books, including borrowing books, returning books, book maintenance management and book scrap management.
1.5.3.3 New book subscription management
New book order management, mainly for new book ordering, new book acceptance, new book storage, new book inquiry and other services.
1.5.3.4 Book Statistics Management
Book statistics management, mainly for the inventory, borrowing statistics, return statistics, etc. of various books in the library.
1.5.3.5 RFID application management
RFID application management, mainly for the conversion of RFID tags, security door access monitoring, self-service loan management system and mobile inventory and other services.
1.5.3.6 System Settings
System settings, mainly for the system to perform user management, password changes, authority settings and system optimization functions.
1.6 Advantages of Project Construction
Simplified process and improved efficiency
The current borrowing and returning process generally uses a barcode scanning system. The collection of barcode data is done through a fixed or handheld barcode scanner. The scanning operation requires manual opening of the book and finding the barcode position before scanning. The operation process is relatively cumbersome. Books are inefficient. The introduction of RFID technology can realize a dynamic, fast, large data volume, and intelligent book borrowing and returning process, improving the security of information storage, the reliability of information reading and writing, and the efficiency and speed of borrowing and returning books.
System expansion improves safety
Optimize the existing book management system through the RFID intelligent book management system, link the anti-theft system with the book circulation management system, and record the historical record of each book in and out of the library, so that it can be matched with the historical record of borrowing and returning books. It can effectively improve the accuracy of the anti-theft system and ensure the safety of books.
Reduce workload and improve job satisfaction
The work of library staff is very heavy due to years of repetitive work. For example, relying on manual book inventory has a large workload, and it is easy to have certain negative thoughts about the work. In addition, readers are dissatisfied with the complex process of borrowing and returning books in the library, resulting in a decrease in library job satisfaction. Through the RFID intelligent library management system, the staff can be liberated from the daily heavy and repetitive work in the library, and personalized services can be customized for different readers, so as to realize the humanized operation process and improve the readers’ understanding of the library work. satisfaction level.
Strong label data retention and long lifespan
Barcode storage data is limited, and it is susceptible to damp, pollution and other limitations, which restricts the management of the library to a large extent. However, the storage area of electronic tags is large, and the data retention capacity can reach more than 100 years. Coupled with the characteristics of waterproof, anti-magnetic, and high temperature resistance, the life of RFID electronic tags is much longer than that of bar codes. Due to the non-contact reading method, each electronic tag can be read more than 100,000 times at least, and the electronic tag can be used for a long time once it is attached.
