What is the Internet of Things?

Through various information sensors, radio frequency identification technology, global positioning systems, infrared sensors, laser scanners, etc. Devices and technologies collect in real time any objects or processes that need to be monitored, connected, and interacted with, and collect various required information such as sound, light, heat, electricity, mechanics, chemistry, biology, and location, and access them through various possible networks. , realize ubiquitous connections between things and things, and things and people, and realize intelligent perception, identification and management of objects and processes.

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.

Capabilities of the Internet of Things

The Internet of Things should have the following three capabilities: comprehensive perception, reliable transmission, and intelligent processing.

①Comprehensive perception: Use RFID, sensors, QR codes, etc. to obtain object information anytime and anywhere, including user location, surrounding environment, personal preferences, physical condition, emotions, ambient temperature, humidity, and user business Feelings, network status, etc.

②Reliable transmission: Through various network integration, business integration, terminal integration, and operation and management integration, the information of the object is transmitted accurately in real time.

③Intelligent processing: Utilize various intelligent computing technologies such as cloud computing and fuzzy recognition to analyze and process massive data and information, and perform real-time intelligent control of objects.

Basic characteristics of the Internet of Things

From the perspective of communication objects and processes, the information interaction between things and people and things 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.

① Overall perception: Radio frequency identification, QR codes, smart sensors and other sensing devices can be used to perceive and obtain various types of information about objects.

② Reliable transmission: Through the integration of the Internet and wireless networks, object information can be transmitted in real time and accurately to facilitate information exchange and sharing.

③Intelligent processing: Use various intelligent technologies to analyze and process the data and information sensed and transmitted to achieve intelligent monitoring and control.
