RFID Digital Library Management System

In Library management, traditional manual management has been gradually replaced by digital management, and the use of barcode recognition, computer network and computer software technology has improved management efficiency. However, library Management still faces some challenges, such as self-service repayment of books, rapid inventory, search and sorting, which affect the management and service level of the library. Therefore, the library industry is actively seeking more advanced technologies to solve these problems.

1. Overview of RFID Technology

1.1 Concept of RFID Technology

RFID (Radio Frequency Identification) is a wireless radio frequency identification technology that identifies specific targets through radio signals and reads and writes related data. It can automatically identify target objects and obtain related data without mechanical or optical contact.

The application history of RFID technology can be traced back to World War II, when it was originally used to identify Allied aircraft. RFID electronic tags mainly include coil type, microstrip patch type and dipole type. Short-range application systems with a working distance of less than 1 meter generally use coil antennas, and remote application systems require microstrip patch or dipole RFID Antennas working in high frequency and microwave bands.

RFID tags have the advantages of being waterproof, anti-magnetic, high temperature resistant, long service life, large reading distance, tag data encryption, large amount of Stored data, and storage information modification. RFID Readers are divided into mobile and fixed types, and are widely used in library management, Access Control systems, food safety traceability and other fields.

1.2 Advantages of RFID technology

High-speed identification: RFID technology can simultaneously identify high-speed moving objects and multiple tags, and the operation is quick and convenient.

Strong anti-interference ability: Short-range radio frequency products are not afraid of harsh environments such as oil stains and dust pollution, and can be used to track objects and other barcodes on factory assembly lines.

Long-distance identification: Long-range radio frequency products are mainly used in transportation, and the identification distance can reach tens of meters, such as automatic toll collection or vehicle identity identification.

Library management advantages: RFID libraries can realize readers' self-service borrowing, 24-hour self-service book return, rapid collection inventory, fast and accurate database inspection and update, automatic sorting, automatic shelving, data storage encryption and other functions, and improve the level of modern library management.

The RFID system consists of three parts: RFID reader/writer, electronic tag (TAG) and application software system. The RFID reader/writer emits radio wave energy of a specific frequency to drive the RFID electronic tag and send the read data to the application for processing.

1.3 Development of RFID technology

Multi-band application: RFID technology is currently mainly used in medium and high frequency bands, especially UHF long-distance RFID of 860-960 MHz. However, due to product crowding, susceptibility to interference and relatively complex technology, the relevant research and application of 2.45 GHz and 5.8 GHz are still in the exploratory stage.

Interdisciplinary integration: RFID technology involves the independent combination of different interdisciplinary professional technologies such as high-frequency technology, microwave and antenna technology, electromagnetic compatibility technology, semiconductor technology, data and cryptography, and manufacturing technology.

Intelligent application: RFID system can realize management functions such as collection, processing and remote transmission of object identification information through Ethernet or WLAN.

Development of electronic tags: RFID electronic tags are the information carriers of RFID systems. They are currently composed of coupling components (coils, microstrip antennas, etc.) and microchips. Future development trends may include smaller and smarter RFID electronic tags.

RFID technology has many advantages over traditional barcode technology. It can save time, manpower and material resources, reduce production costs and improve work efficiency. Therefore, more and more people believe that RFID technology is a substitute for barcode technology, and electronic tags are the ultimate product in the future label market.

1.4 Application of RFID technology in library management

RFID technology uses radio frequency signals for data transmission and reply. The RFID smart label or ordinary RFID label can transmit and store information. The RFID smart label is composed of adhesive labels and ultra-thin radio frequency labels. It combines the advantages of radio frequency technology and label printing. The smart label can be programmed multiple times and follows the coding rules when it was originally made.

According to the different frequencies, RFID electronic tags can be divided into low frequency, high frequency, ultra-high frequency and microwave electronic tags. According to the different packaging forms, electronic tags can be divided into credit card labels, linear labels, paper labels, glass tube labels, circular labels and special purpose abnormal labels.

RFID readers communicate wirelessly with RFID electronic tags through antennas, and can read or write the identification code and memory data of tags. Typical RFID readers include high-frequency modules (transmitters and receivers), control units, and read-write antennas. Compared with barcodes, RFID has the characteristics of batch reading, erasable data, and real-time response. Libraries can use RFID technology to achieve various contactless management, including data of readers and collections. In recent years, libraries have used RFID technology to replace barcode recognition, which has improved operational efficiency and accuracy, but the essence of the service model has not changed.

1.4.1 Self-service borrowing and returning system to improve circulation efficiency

The transition from traditional libraries to service-oriented digital libraries has brought about profound changes in library service content and service models. Modern libraries have gradually shifted from paper resources to digital resources, from library borrowing to remote acquisition, from location services to network services, from single services to diversified services, and from literature to multimedia activities, achieving a major shift in people-oriented.

The traditional library borrowing process is relatively complicated, with a large workload, a large amount of anti-theft supervision, and high labor costs. When readers enter the library and want to borrow a book, they need to go to the service desk to manually query the service, then go to the corresponding bookshelf to find the book, and then take the book to the borrowing desk for registration and manual magnetization, and finally complete the borrowing process through the library anti-theft antenna.

The self-service borrowing and returning system based on RFID technology has changed this situation. Readers can borrow books directly through the self-service borrowing and returning system without demagnetizing the books. They only need to pass the books through the library anti-theft antenna to complete the borrowing process. The self-service borrowing and returning system based on RFID technology can provide self-service borrowing, self-service return, self-service card processing, appointment to pick up books, pre-checking of returned books, visual browsing surface conversion/PDP book browsing, real-time interaction with central library data, automatic book notification and other services. The self-service borrowing and returning system provides multiple language interfaces, a friendly human-computer communication interface that can complete the borrowing/returning services of multiple books at one time, has offline processing functions, provides color selection that is harmonious with the library's on-site environment, and improves the circulation efficiency of book borrowing.

1.4.2 The application of intelligent shelf system significantly improves the work efficiency of the library

The traditional manual warehouse-smart-inventory-rfid-bookshelf.html target='_blank'>book inventory has a large workload, especially the low efficiency of bookshelf book inventory. Librarians need to rely on memory to classify, place and record books, which is time-consuming and labor-intensive, and difficult to achieve the goal.

The intelligent shelf system based on RFID technology consists of a circulation loan system, a document positioning system and a document collection system. It can establish shelf signs, build an intelligent application environment, realize document positioning navigation, flexible and diverse book shelves, and support self-service. The intelligent shelf system solves the problems of book shelves, document shelves, shelves and automatic search, greatly reduces the workload of library staff, and significantly reduces the error rate, thereby improving work efficiency.

1.4.3 Change borrowing management and strengthen the development and utilization of documents

The low enthusiasm and efficiency of traditional library staff and the high number of reader complaints need to be improved urgently. Some staff lack service concepts, think that library work is simple, and are unwilling to strengthen learning. At the same time, most staff lack document development and utilization skills, resulting in rich collections of documents but low utilization rate.

The application of RFID technology can deeply process documents and digital resources, including ordinary paper medium document processing, ancient book rare book processing, microfilm document processing, audio and video processing, and special resource processing (such as public opinion, oracle bone inscriptions, etc.). These processing work enables effective documents to be properly processed and promoted, thereby improving the development and utilization rate of documents.

1.4.4 Change management and work mode to improve job satisfaction

Evaluating readers' service attitude, efficiency and service level of library staff is an important criterion for testing the service quality of library staff. The management concept and management mode of the library directly affect the satisfaction of library staff. In order to improve the satisfaction of employees, the library must be effectively managed to achieve legality, rationality and rationality.

Based on the RFID entire library system management technology, the repetition rate and monotony of library staff will be greatly reduced, and the hands of library staff will be fully liberated, so that their work is no longer monotonous and boring. In this way, library staff have more time to invest in the research and use of new business, which improves the job satisfaction of library staff and also improves the satisfaction of library readers with library work. Strengthening library management through RFID technology, meeting readers' needs, and realizing the improvement of the technical system.

2. Application of RFID technology in library management system

2.1 Design concept of RFID library management system

Compared with ancient libraries and modern libraries, modern libraries have undergone great changes in collection content, document processing methods and service concepts.

First, the collection content of modern libraries has changed greatly. With the rapid development of the publishing industry, modern libraries not only collect books and manuscripts, but also journals, newspapers, micro documents, audio-visual materials and a large number of non-book materials.

Secondly, with the diversification of document types, the processing methods of documents have also changed. Traditional library work mainly focuses on the classification, placement and recording of documents, while modern libraries pay more attention to serving the needs of readers and regard document provision as the core service content.

Finally, modern libraries take service as the core concept and information technology as an important technical support. The entire working mechanism of the library revolves around the needs of readers. Through the application of information technology, it provides functions such as fast borrowing and returning, high-speed inventory, fast search, positioning and navigation, and improves the management efficiency of the library and the satisfaction of readers.
