What is the concept of Internet of Things?

The Internet of Things (IOT) refers to the real-time collection of any object or process that needs to be monitored, connected, and interacted with through various information sensors, radio frequency identification technology, global positioning systems, infrared sensors, laser scanners, and other various devices and technologies, and the collection of its acoustic, optical, thermal, electrical, mechanical, chemical, biological, location, and other kinds of needed Through various kinds of possible network access, it realizes the ubiquitous connection between things and objects and between things and people, and realizes intelligent sensing, identification and management of objects and processes. The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc., which allows all ordinary physical objects that can be independently addressed to form an interconnected network.

The Internet of Things (IoT, Internet of things) that is, "the Internet of everything is connected", is an extension and expansion of the network based on the Internet, a variety of information sensing devices and the Internet combined with the formation of a huge network, to achieve at any time, any place, people, machines, and things are interconnected[

The Internet of Things is an information carrier based on the Internet, traditional telecommunications networks, etc. It allows all ordinary physical objects that can be independently addressed to form an interconnected network, things are interconnected at any time and any place[2] .

The Internet of Things (IoT) is an important part of the new generation of information technology, which is also known as Pan-Interconnection in the IT industry, meaning that everything is connected and everything is connected. As a result, "the Internet of Things is the Internet of things connected". This has two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network on the basis of the Internet; second, its user end extends and expands to any item to item for information exchange and communication. Therefore, the Internet of Things is defined as a network that connects any item to the Internet for information exchange and communication through information sensing devices such as radio frequency identification, infrared sensors, global positioning systems, laser scanners, etc., according to agreed protocols, in order to realize intelligent identification, localization, tracking, monitoring, and management of items.

Basic Characteristics of the Internet of ThingsFrom the point of view of the communication object and process, the information interaction between things and things, people and things is the core of the Internet of Things. The basic features of IoT can be summarized as holistic sensing, reliable transmission and intelligent processing[5] .

Overall Sensing - Sensing devices such as RFID, QR codes, smart sensors and other sensing devices can be utilized to sense and obtain various types of information about objects.

Reliable transmission-Through the integration of the Internet and wireless networks, the information of the object is transmitted in real time and accurately, so that the information can be exchanged and shared.

Intelligent processing-Use various intelligent technologies to analyze and process the sensed and transmitted data and information to realize the intelligence of monitoring and control. According to the above characteristics of the Internet of Things, combined with the viewpoint of information science, around the flow process of information, can be summarized as the function of the Internet of Things to deal with information:

(1) the function of obtaining information. Mainly information perception and recognition, information perception refers to the perception and sensitivity to the state of the attributes of things and the way they change; information recognition refers to the ability to represent the perceived state of things in a certain way. (2) The function of transmitting information. Mainly information sending, transmitting, receiving and other links, and finally the task of transmitting the acquired information about the state of things and the way they change from one point in time (or space) to another, which is often referred to as the communication process. (3) The function of processing information. It is the process of processing information, utilizing existing information or perceived information to produce new information, and is actually the process of making decisions. (4) The function of applying information. Refers to the process of the final utility of the information, there are many forms of expression, the more important is through the regulation of the object of the state of things and its transformation, always make the object in the pre-designed state
