What is the Internet of Things?

Release time: 2022-09-05

The Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected, and interacted with through various devices and technologies such as information sensors, radio frequency identification technology, global positioning systems, infrared sensors, and laser scanners. , and the collection of various required information, such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., as well as the ubiquitous connections between things and people through various possible network access. The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc. It enables all independently addressable common physical objects to form an interconnected network.

The basic characteristics of the Internet of Things From the perspective of communication objects and processes, the information interaction between things and people is the core of the Internet of Things. The basic characteristics of the Internet of Things can be summarized as overall perception, reliable transmission, and intelligent processing.

Overall perception - sensing devices such as RFID, two-dimensional codes, and smart sensors can be used to perceive and obtain various information about objects.

Reliable transmission - through the integration of the Internet and wireless networks, real-time and accurate transmission of object information to achieve information exchange and sharing.

Intelligent processing—Using various intelligent technologies to analyze and process the data and information sensed and transmitted to realize intelligent monitoring. According to the above characteristics of the Internet of Things, combined with the point of view of information science, the role of the Internet of Things in processing information can be summarized as follows:

(1) The function of obtaining information. It is mainly about the perception and recognition of information. The perception of information 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 express the state of things you feel in a certain way. (2) The function of transmitting information. Its task is to send, transmit and receive information, and finally transfer the obtained state information of things and the way they change from one time point (or space point) to another time point (or space point), which is commonly referred to as dissemination process. (3) The function of processing information. It refers to the process of information processing, using existing information or perceived information to generate new information, which is actually a decision-making process. (4) The function of application information. It refers to the process by which information is finally used, and it has various forms of expression. What's more important is to keep the object in a pre-designed state by adjusting the state of the object and how it transforms.
