What is the Internet of Things?

Through various devices and technologies, such as information sensors, radio frequency identification technology, global positioning system, infrared sensors, laser scanners, etc. Any object or process that needs monitoring, connection and interaction is collected in real time, and all kinds of needed information such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc. It is collected and accessed through various possible networks to realize the ubiquitous connection between things and people.

Internet of Things is an information carrier based on Internet and traditional telecommunication network, which makes all ordinary physical objects that can be addressed independently form an internet.

The ability of internet of things

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

① Comprehensive perception: using RFID, sensors, QR codes, etc. Get the information of the object anytime and anywhere, including the user's location, surrounding environment, personal preferences, physical condition, mood, environmental temperature and humidity, as well as the user's business experience and network status.

(2) Reliable delivery: Real-time and accurate delivery of object information through various network integration, business integration, terminal integration and operation management integration.

③ Intelligent processing: By using various intelligent computing technologies such as cloud computing and fuzzy recognition, massive data and information are analyzed and processed, and real-time intelligent control of objects is carried out.

Basic characteristics of the Internet of Things

From the communication object and process, 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 holistic perception, reliable transmission and intelligent processing.

① Overall perception: RFID, QR code, smart sensor and other sensing devices can be used to perceive and obtain various information of objects.

② Reliable transmission: Through the integration of Internet and wireless network, the information of objects can be transmitted in real time and accurately, and information can be exchanged and shared.

③ Intelligent processing: analyzing and processing the sensed and transmitted data and information by using various intelligent technologies to realize intelligent monitoring.
