With the rapid development of information technology, the Internet of Things is considered to be the fourth information revolution in the scientific and technological world after computers, the Internet and mobile communication networks. As an important center for information industry applications, libraries look back on their development history and find that every change in information technology will promote a leap forward in library management and services. As the fourth wave of the development of the information industry, the Internet of Things will definitely promote intelligent library management models, humanized services, and more efficient work, thereby realizing the transformation from current digital libraries to smart libraries.
Internet of things concept
In 1999, the Automatic Identification Center of the Massachusetts Institute of Technology first proposed the concept of the Internet of Things. In 2005, the International Telecommunication Union (ITU) released the “ITU Internet Report 2005: Internet of Things” at the World Summit on the Information Society, formally defining the concept of the Internet of Things. [1] The Internet of Things connects any item to the Internet through information sensing equipment such as QR code reading equipment, radio frequency identification (RFID) devices, infrared sensors, global positioning systems, and laser scanners according to agreed protocols. , a network that carries out information exchange and communication to achieve intelligent identification, positioning, tracking, monitoring and management. [2] It is an extension and expansion of the communication network and the Internet. It uses various information sensing devices to sense and identify various entities in the physical world, and realizes real-time control and precise management of these entities through network transmission and interconnection. .
1.2 Characteristics of the Internet of Things
The Internet of Things is an information network that connects objects with comprehensive perception of objects, reliable transmission and intelligent processing of information. [3] It has the characteristics of intelligence, ubiquity and integration.
(1) The intelligent Internet of Things is a network formed by the combination of various information sensing devices and the Internet that can realize fully automatic and intelligent collection, transmission and processing of information between objects and people and objects, thereby achieving intelligent identification and scientific A vast intelligent network managed. [4] Therefore, after the introduction of Internet of Things technology in the library field, various micro-sensor chips can be embedded in objects, and through network systems such as broadband interaction, wireless communication, and multimedia, it can provide readers with high-quality, thoughtful, convenient, and fast services. , to meet the diverse information needs of readers.
(2) The ubiquitous Internet of Things is connected to information systems through the computer Internet, thus forming a ubiquitous and all-encompassing network. It aims to achieve smooth communication with anyone and anything at any time, any place, and has omnipresence, all-inclusive, and omnipotence as its basic characteristics.
(3) The convergent Internet of Things is the product of information technology changes. It is a new technology system that integrates three core technologies: radio frequency identification technology, sensing technology and short-range communication technology. It establishes a connection between the physical world and the virtual world that were completely separated in the past, thus integrating the originally separated physical infrastructure and information infrastructure into a unified infrastructure, realizing the two-way flow of information between the physical world and the virtual world.

Development status of Internet of Things
Development status at home and abroad: The research and application of the Internet of Things abroad started earlier. The United States, Germany, Japan, South Korea, Singapore and other countries have issued plans for the construction of Internet of Things infrastructure and regard the Internet of Things as a new way to revitalize the economy. growth point. At present, IoT technology has been widely used in smart homes, smart logistics, industrial automatic control, smart transportation, smart agriculture and other fields. It not only generates economic benefits, but also drives the development of related industries. In our country, when Premier Wen Jiabao inspected Wuxi Science and Technology Park in August 2009, he proposed that “China’s sensing information center, or sensing China center, should be established as soon as possible.” [7] Premier Wen’s speech pushed the research and application development in the field of Internet of Things in my country to a climax. Wuxi took the lead in establishing the “Sense China” research center. The Chinese Academy of Sciences, operators and many universities established Internet of Things research centers in Wuxi. hospital. In 2010, the Internet of Things was officially listed as one of the country’s five emerging strategic industries and included in the “Government Work Report”. This has opened a new chapter in the research and application of the Internet of Things. The anti-intrusion system established at Shanghai Pudong International Airport in 2010 is a successful case of the application of the Internet of Things. The system has laid more than 30,000 sensor nodes, covering the ground, fences and low-altitude detection, and can prevent offensive intrusions such as people climbing over, stowaways, and terrorist attacks. ［
