　1. Overview of the RFID library project

　　1.1 Introduction to RFID Library Project

RFID (Radio Frequency Identification System) is a “radio frequency identification system”, a non-contact automatic identification technology, which uses radio waves to identify the mark on the target to perform wireless data identification and obtain related information.

The library RFID system is the application of RFID technology to the management of the library to help the library realize the functions of rapid borrowing, rapid return, rapid inventory data inventory, automatic book shelf arrangement, shelf reversal, and security and anti-theft.

　1.2 The role of RFID libraries

For many years, the management and staff of the library have been plagued by problems such as book borrowing and returning, quick inventory, searching, and sorting out books in disorder. Relying on strong RFID technical strength, Chuangyi Technology has formed a series of library supporting equipment after years of research and development efforts, which greatly improves management methods, increases work efficiency, reduces the labor intensity of management personnel, and provides a complete solution for the library application field plan.

Build an RFID library. The RFID system is used to identify, track, and protect all library materials, and realize the intelligentization of book borrowing and returning, ordering, searching, and inventory inventory. The purpose is to greatly improve the efficiency of library materials processing.

Through the connection of Beijing Chuangyi RFID radio frequency technology and the existing library automation system, the self-service system can be smoothly and smoothly connected to it, to realize the automation of the management of books and materials, speed up the inventory of books, and increase the circulation rate of books, which is more effective Give full play to the information transmission function of books and materials.

The construction of the library’s RFID system will simplify the reader’s borrowing process, improve circulation efficiency, greatly reduce the workload of book inventory and search, and liberate library staff from the complicated and repetitive work, which is more effective and targeted. Provide personalized services for readers and improve the quality of library services.

　　1.3 RFID library system content and structure

The construction content of this project mainly includes two aspects: the installation and commissioning of Chuangyi RFID system equipment and the planning and implementation of RFID system supporting software. These two aspects are combined with each other, guaranteed by a scientific and reasonable management mechanism, and building a world-leading level The RFID library application system strives to build a modern library with rich digital resources, advanced management, diverse service types, innovative service methods, convenient use by readers, safe and reliable systems, and strong scalability.

The library RFID system is composed of RFID hardware, computer integrated equipment, and software. The RFID hardware is connected to the computer integrated equipment through a standard serial port or USB interface to form the terminal of the library RFID system. The RFID system terminal is connected to the library management system service center through the terminal software. Connection, its physical connection is network connection or data copy exchange. 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.

　1.6 Innovations Brought by RFID System

Simplify the process of borrowing and returning books

Although the existing book borrowing and returning process introduces a barcode scanning system, it still needs to manually open the book’s title page and find the position of the barcode before scanning the barcode. Such an operation process is relatively cumbersome, and the efficiency of borrowing and returning books is low. At the same time, the barcode is easy to break, and it often happens that the barcode cannot be read and the barcode needs to be replaced. This will not only affect the efficiency of borrowing and returning books, but also affect the reader’s satisfaction with the library. Therefore, it is urgent to introduce advanced reading and writing technology to realize the intelligent book borrowing and returning process, improving the security of information storage, the reliability of information reading and writing, and the speed and speed of borrowing and returning books.

Reduce the workload of inventory and search

Relying on manual book inventory work, the workload is large and the efficiency is low. Administrators have to classify, place and record books based on their own memory, which is time-consuming and difficult to achieve. It is necessary to introduce advanced technology to realize the intelligentization of book inventory.

Improve the security of the anti-theft system

The accuracy of the existing library magnetic stripe anti-theft system is low, and the magnetic stripe is easily weakened, so the probability of false alarms and false alarms is high. Therefore, it is necessary to improve the existing book anti-theft system and adopt more reliable anti-theft technology.

Change the disconnection between borrowing management and security and anti-theft

The library anti-theft system is still an isolated system. Books must be magnetized before being returned and put on shelves, and demagnetized when they are loaned out. The workload is heavy, which directly affects the efficiency of book circulation and management. It is impossible to record the information of the stolen books while discovering the theft, which has a great impact on the daily inventory and replenishment of books. Therefore, it is necessary to improve the existing 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.

Improve the satisfaction of library staff

Due to the repetitive work of the library staff over the years and the heavy work 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 The readers are also very troubled, and the readers are also dissatisfied with the library, resulting in a decrease in the satisfaction of library staff with the work of the library. Through the technical transformation of the library management system, technical means can be used to make up for the shortcomings in management, and at the same time liberate the staff from the heavy daily work of the library.

Improve readers’ satisfaction with borrowing and returning books

Readers often feel dissatisfied with the library. The main reasons are as follows:

1) The efficiency of borrowing and returning books is low, the waiting time in line is too long, and the unnecessary waste of time leads to dissatisfaction of readers;

2) The bar code of the borrowed and returned book cannot be read, which increases the waiting time of the reader and causes the reader to be dissatisfied;

3) Since the library does not have an effective means to inventory books, readers found a certain book in the collection through the query system, but it took a long time to find it. The reason may be that the book was stolen, but because of management The system does not have accurate records, and as a result, readers are dissatisfied with the library;

Through the above analysis, it can be concluded that many problems in current library management and many inconveniences for readers in borrowing and returning books are caused by the defects of the barcode technology currently used. If RFID is used, many functions that cannot be achieved by barcode technology can be realized, thereby improving the function and system reliability of the library’s management system.

　2.3 System structure

　　2.4 Interface standards and protocols

The RFID system is an integral part of the library. It is a new generation of intelligent library management system attached to the library management system. Therefore, the system must be connected with the library’s business system to exchange data.

Currently, the attached communication protocols and standards are

1) TCP/IP protocol

TCP/IP (abbreviation for Transmission Control Protocol/Internet Protocol, Chinese translated as Transmission Control Protocol/Internet Protocol) protocol is the most basic protocol of the Internet, TCP/IP is a combination of two network basic protocols: IP protocol and TCP protocol name . The development of the TCP/IP protocol began in the 1970s. It is an important protocol for network interconnection, including:

Internet Protocol IP: A common communication protocol that makes the Internet a network that allows the connection of different types of computers and different operating systems. To enable two computers to communicate with each other, the two computers must use the same “language”. The communication protocol is just like the common language used by two computers to exchange information. It stipulates the agreement that the two parties should abide by in the communication.

Transmission Control Protocol TCP: Although the computer can ensure that data can be sent and received between computers by installing IP software, the IP protocol cannot solve the problems that may occur during the transmission of data packets. Therefore, in order to solve the possible problems, the computer connected to the Internet also needs to install the TCP protocol to provide reliable and error-free communication services.

　　2.5 RFID application software system design

The application software platform of the RFID system is the basic software platform for the operation of the entire RFID system. Through this platform, various RFID application hardware devices are assembled into a unified whole and perform corresponding functions.

　　3. Introduction of Chuangyi Library RFID Products

3.1 RFID tags

RFID tag is a passive low-current integrated circuit product with antenna and chip. It can write and read basic information of books and media in the storage chip multiple times. It is used as a label for books and multimedia CD-ROM data. Recognition, the various labels we provide are described below. Just like a barcode, the intelligent library system uses a set of data stored in the label to “point to” the corresponding bibliographic record of each book material in the library’s circulation automation system database. Taking into account many privacy protection issues, the title and other details of any books are not stored in the label. The smart circulation tag provides 512bit programmable information for each book, and can be quickly read through a simple UHF radio frequency (840-960MHz) in the industry’s widest channel of 1.2 meters. Because in the process of borrowing and returning, do not copy the information of the smart circulation label, so the processing time of the procedures is greatly reduced. Through advanced anti-collision algorithms, error detection and error correction methods, it allows multiple tags to be read at the same time. The smart circulation label is designed as a label dedicated to books, with good concealment, and its anti-theft performance is equivalent to that of a magnetic stripe.
