Project Overview
With the development of science and technology, the progress of society, and the continuous advancement of information construction, readers have higher and higher requirements for library service quality. How to improve service quality, strengthen internal management, and improve work efficiency are all problems that library leaders need to solve urgently. Build the network operating environment of the RFID intelligent library collection management system and deploy the corresponding RFID hardware equipment. It is used to identify, track, and protect all the materials in the library, and realize the functions of book borrowing and returning, ordering, searching, and inventory counting through the RFID system, which greatly improves the efficiency of library materials processing. The emergence of RFID intelligent library management system, Development, maturity, and wide application have completely solved the problems that the library currently needs to solve.
Normally, after the library implements RFID technology, with the same number or fewer librarians, the library’s material circulation will be greatly improved.
The early application of RFID technology in libraries in my country is no different from the situation in library circles in the world. It basically originated from HF (high frequency) technology. In recent years, with the maturity of UHF (ultra high frequency) technology, the decline in tag prices, the acceleration of reading speed, and the improvement of safety performance, the application of UHF (ultra high frequency) has gradually surpassed HF (high frequency) and occupied the market. leading position. Judging from the application of RFID in the national Internet of Things, the development of UHF (ultra-high frequency) technology has also been significantly accelerated. The country has listed it as the top priority of the national development strategy and has become the main direction of RFID development in the future.
Based on the above understanding, Shenzhen Wanquan Intelligent and relying on strong UHF R&D and manufacturing capabilities, UHF RFID applications in libraries and other documents. After unremitting efforts, a series of library application equipment with excellent performance has been developed, which provides a reliable solution for the application of smart libraries. With the continuous advent of the company’s new research and development products, the company will provide more and greater help for the further development of smart libraries in the future.

Outline design
1. Summary ideas
Information technology is the most important technical support of modern libraries. Collection of books and documents is the most basic resource entity of the library, and the provision of documents is the most important service content of the library. At present, the technical means of “secure magnetic stripe + barcode” is widely used in the domestic library management system. The security magnetic stripe is used as the safety guarantee of the books, and the barcode is used as the ID card of the books, which solves some problems in the book management, but there are still some problems. There are many problems. With the use of barcodes, the barcodes of many books fall off and cannot be borrowed or returned normally. The use of RFID technology has the characteristics of high security, good concealment, and long service life, and can better liberate the library. The labor force of the staff can quickly realize the borrowing and returning of books.
2. The overall process
The system utilizes related circulation equipment and RFID reading and writing equipment to realize the functions of self-service borrowing and returning of books, librarian workstations, inventory search, anti-theft, etc., as shown in the following operation example 2.1.
2.1 Examples of Library Use
Introduction to RFID system
RFID is a non-contact automatic identification technology. It uses radio frequency signals to automatically identify target objects and obtain relevant data. The identification work does not require human intervention. The RFID application system has a series of advantages such as non-contact, long working distance, high precision, automatic and fast information collection and processing, and good environmental adaptability. It can not only replace the traditional manual entry method, greatly improve the operating efficiency of the enterprise, but also because of its advanced The automatic identification function can easily achieve tasks that were previously difficult to complete manually, and provide strong support for improving the competitive advantage of the enterprise and enhancing the core competitiveness of the enterprise.
The most basic RFID system consists of the following three parts, the principle is shown in the figure below:
1) Tag: consists of coupling components and chips, each tag has a unique electronic code, attached to the object to identify the target object;
2) Reader: A device for reading (and sometimes writing) tag information, which can be designed as a handheld or fixed type;
3) Computer system: including middleware, system application software, etc.
RFID system principle
An electronic tag generally stores electronic data in an agreed format. In practical applications, the electronic tag is attached to the surface of the object to be identified. The reader can read and identify the electronic data stored in the electronic tag without contact, so as to achieve the purpose of automatically identifying the object. Usually the reader is connected to the computer, and the read tag information is transferred to the computer for further processing. The RFID information processing system (ie, back-end application support software) integrates the tag data collected by the reader.
System composition
The RFID library system consists of hardware, computer integrated equipment, and software. Data exchange through network connection or data copy. The connection between the terminal software and the library management system service center complies with the relevant protocols in the library industry and computer network protocols. The system topology is as follows:
1. Software composition
The software includes two parts: system software and customized R&D software. The system software includes database management system, application middleware and character recognition OCR software. The functional structure of the custom-developed library management system is as follows:
Label conversion and production complete the production of RFID tags, the borrowing and returning system realizes the circulation and borrowing management of books, and the literature search is convenient for borrowers or staff to search for books, and the shelf and navigation system provides intelligent and fast book positioning and positioning. Shelves, collection lists provide an intelligent library, and the book catalog management system is for the library to manage the national book catalogs.
2. Hardware composition
(1) Computer host network equipment
The system includes a database system and an application system, which need to be deployed on a server. This system needs a server for system operation. The return of RFID tag data in the library is realized by a combination of wireless network and wired network. A wireless AP is deployed in each library for the signal access of handheld devices and smart library carts. The wireless AP is connected to the core switching equipment through a wired network, and the computer network is deployed through the ceiling.
(2) Safety equipment
In order to monitor the books for the personnel entering the library, this system uses RFID radio frequency technology to automatically transmit the books to the network database.
The RFID book management system includes: label conversion system, self-service book borrowing system, self-service book return system, intelligent search system, cart-type inventory system, and security door detection system.
(3) RFID related equipment
For RFID tags in the system, there are multiple types of book RFID tags, shelf tags, layer tags, etc., and label printing equipment is required. Books and RFID tags store the basic ID of a book, and it is not recommended to store information; the shelf label adopts a passive label, which is used to store the single-sided and single-linked information of a book shelf, while realizing long-distance information transmission and sub-region; layer labeling It is used to store the single-sided single-layer information of a book shelf, etc.
Smart book inventory vehicles and handheld devices can support reading and writing UHF and active tags. Through the RFID reader to read the RFID tags pasted on the literature, the library shelf, and the RFID borrowing library card, with the help of the back-end RFID management system and the library automation integration system, the borrowing of the literature, the library shelf, and the staff can be realized. Integrated management of return, return and collection.
3. RFID project and library software interface
The system supports the library SIP2 interface, which can be well compatible with the existing campus library management system library management system.
System Features
1. The principle of practicality
Under the condition of meeting system application function requirements and system performance requirements, and ensuring the safety and reliability of the system, software, hardware, and network products are all selected systems and products with the highest performance-to-price ratio. The entire system should be easy to manage, easy to maintain, easy to operate, easy to learn, easy to use, easy to configure the system, well monitored and controlled in terms of equipment, safety, data flow, performance, etc., and can be remotely managed and fault diagnosed .
2. Security principle
The user’s data on the information platform is the user’s business secrets, and maintaining the user’s data security and confidentiality is to maintain the authority and credibility of the information platform. Therefore, it is very important to adopt advanced security technologies such as authentication technology, key technology and WEB security access technology to improve the security and confidentiality of the system.
3. The principle of reliability
The system provided by the platform needs to have error handling, fault tolerance, and redundant backup capabilities, so that the entire logistics business information system will not be paralyzed due to partial failures. All core equipment, including host servers, core switches, etc., adopt redundant design solutions to ensure that: one equipment fails, the other equipment can continue to work without losing data, and the failed equipment is isolated and The operation of the system will not be affected when repairing.
4. Advanced principle
First of all, the selection of the system platform should be advanced. Choose advanced technology and mature products, and at the same time have perfect after-sales service; secondly, system planning and design should be advanced. Adopt advanced system planning and design concepts, technologically advanced computer software and hardware and network technology for design and development.
5. Standardization principle
All aspects of the system platform, network management, project management, system maintenance specification formulation, etc. all follow common international or industry standards, so that the system can support the interconnection of various heterogeneous platforms and different network protocols.
6. The principle of scalability
Business requirements will continue to evolve, and when the existing system cannot meet application requirements, the system will face upgrading. Therefore, the design of the system must have a certain expansion capability, leaving room for upgrades to meet the needs of future business development.
RFID library application advantages
Electronic tags (RFID) have a dual role: on the one hand, identification is used to track and count items; on the other hand, they are used for security protection of items. In other words, RFID has both identity recognition and anti-theft functions. This feature of RFID has greatly improved the data processing capability, and the data circulation process can be completed quickly and accurately through a simple single operation.
1. Simplify the process of borrowing and returning books and improve circulation efficiency
The existing process of borrowing and returning books still needs to manually open the title page of the book and find the position of the barcode before scanning the barcode. Such an operation process is still relatively cumbersome, and the efficiency of borrowing and returning books is relatively low. At the same time, the barcode is easy to break, which will not only affect the efficiency of borrowing and returning books, but also affect the degree of satisfaction of borrowers with the library. Therefore, it is necessary to introduce advanced reading and writing technology to realize an automated book borrowing and returning process, improving the security of information storage, improving the reliability of information reading and writing, and increasing the speed of borrowing and returning books. The self-service borrowing and returning of books in the RFID system supports the borrowing and returning of more than 10 books at a time (limits can be flexibly set), and the efficiency is greatly improved.
2. Significantly reduce the workload of book inventory and search
Relying on manual book inventory work, especially the workload of bookshelf books is too large and the efficiency is very low. Librarians need to classify, place and record the books on the bookshelves according to their own memory, which is time-consuming and difficult to achieve. The introduction of advanced RFID book inventory tools and methods can realize automatic or semi-automatic book inventory. RFID has the characteristics of non-contact, long-distance, and fast reading of multiple tags, which makes the inventory work simple and effective. RFID makes it easy to inventory from inability to inventory; similarly, it can easily realize the functions such as the shelf; when it is put on the shelf, it can be based on the library The physical route (equivalent to electronic ground) instructs the librarian to visit the collection at the correct location.
3. Change the disconnection between the borrowing management and the safety and omission prevention process
The library anti-theft system is still an isolated anti-theft system. Books must be magnetized before being returned and put on the shelves. Books must be demagnetized when they are loaned out. The workload is relatively large, which directly affects the efficiency of book circulation and book management. It is impossible to record the information of the lost books while discovering the lost books, which has a great impact on the daily inventory and replenishment of books. The RFID system improves the existing management system, links the omission prevention system with the book circulation management system, records the historical record of each book’s entry and exit, so that it can match the historical record of the borrowed and returned books.
4. Improve the job satisfaction of library staff
Due to the repetitive work of the library staff over the years and the heavy workload of the library itself, it is easy for the library staff to have certain negative thoughts about the work of the library; due to the flaws in the management, the library management Librarians are also very troubled with the management of the library, and borrowers also expressed dissatisfaction with the library, resulting in a decrease in library staff’s satisfaction with library work. Through the application of the library’s RFID system, it can make up for the shortcomings in management, and at the same time liberate the staff from the daily heavy and repetitive work of the library, which is mainly reflected in the following aspects:
1) RFID technology greatly reduces the workload of circulation, and the remaining circulation work is also automated with RFID technology, which greatly improves the enthusiasm and mental outlook of circulation librarians.
2) RFID technology has also liberated a large number of circulation librarians, allowing them to engage in other advanced consulting work, such as mobile services, holding lectures, exhibitions, and training.
3) The main work of library staff is shifting from circulation to consulting, which will help the library improve the quality of its staff. More professionals will join, which will help improve other services of the library.
5. Improve the satisfaction of borrowers
1) Borrowers often feel dissatisfied with the library. The main reasons are as follows:
①Because the library does not have effective means to take inventory of books, but because the management system does not have accurate records, the result is that books can be found in the borrower system, but they are actually not found;
②Because the efficiency of borrowing and returning books is low, the waiting time for borrowing and returning books is too long, and the borrower wastes time needlessly, resulting in dissatisfaction;
③In the borrowed and returned books, there are information reading errors and the barcode cannot be read, which increases the waiting time of the borrower and causes the borrower to be dissatisfied.
With the continuous enhancement of service awareness in the whole society, borrowers have higher and higher requirements for library services. The library needs to urgently improve the service level and improve the satisfaction of borrowers.
2) The use of RFID systems in libraries can have the following impacts on borrowers:
①Avoid waiting in line, which is more convenient and faster;
②Privacy and independence;
③New feelings brought by high-tech.
6. Changed the service mode of the library
1) Reorganization of library business processes: RFID has liberated a large number of people in the circulation department, making library business process reorganization necessary and feasible; the library will shift from collection-centric to borrower-centric, and provide to borrowers The service will be diversified, advanced and humanized.
2) The importance of reference consulting work is becoming more and more prominent: the reference work of the library is an intermediary between the borrower and the information materials, thus distinguishing the library from general information tools or networks. After the circulation work of the library fades, the reference and consultation work will become the main work of the library.
3) Dissatisfied with the development of field services and traditional services, make full use of various facilities and technical conditions to provide diversified and personalized services to the public, extend the breadth and depth of the library’s services, and improve the ability of public cultural services.
7. The library adopts RFID technology for comprehensive digital management
In addition to books, CD-ROMs, and collections of treasures, the library also needs to digitize other aspects of management. For example: the management of borrowers, administrative management, small consumption, etc., traditional management is time-consuming, laborious, inefficient, and very inconvenient for borrowers and librarians. Through RFID technology, these links can be effectively digitized.
Through the use of RFID technology, the library can realize the function of fast inventory counting, real-time information identification and security and anti-theft functions when borrowing/returning books, fast and accurate database checking and updating functions, etc., which makes the work of librarians even more Easy and simple.
The RFID tag system can be used at the same time as the traditional security system, and can be seamlessly connected with the existing library infrastructure and integrated library system (ILS).
In summary, the benefits of RFID to libraries are obvious. These benefits ultimately boil down to “strengthening library management and meeting the needs of borrowers.”
