What is the Internet of Things?

The Internet of Things is an important part of the new generation of information technology. Its English name is "The? Internet? Yes? Things. Therefore, as the name implies, "the Internet of Things is the Internet where things are connected".

This has two meanings:

First, the core and foundation of the Internet of Things is still the Internet, which is an extension and expansion network based on the Internet;

Second, its customers extend to any goods and exchange information and communicate with each other. Therefore, the definition of the Internet of Things is a kind of network that connects everything with the Internet according to the agreed protocol through RFID, infrared sensor, global positioning system, laser scanner and other information sensing devices, exchanges and communicates information, and realizes intelligent identification, positioning, tracking, monitoring and management of items.

The first is the wide application of various sensing technologies. A large number of different types of sensors are deployed on the Internet of Things. Each sensor is an information source, and the content and format of information captured by different types of sensors are different. The data obtained by the sensor is real-time, and environmental information is collected periodically at a certain frequency, and the data is constantly updated. ?

Secondly, it is a ubiquitous network based on the Internet. The important foundation and core of the Internet of Things technology is still the Internet, which integrates with the Internet through various wired and wireless networks to transmit the information of objects in real time and accurately. The information regularly collected by sensors on the Internet of Things needs to be transmitted through the network. Because of its huge quantity, a huge amount of information has been formed. In the transmission process, in order to ensure the correctness and timeliness of data, it is necessary to adapt to various heterogeneous networks and protocols.

In addition, the Internet of Things not only provides the connection of sensors, but also has the ability of intelligent processing and intelligent control of objects. The Internet of Things combines sensors and intelligent processing, and uses various intelligent technologies such as cloud computing and pattern recognition to expand application fields. Analyze, process and process meaningful data from the massive information obtained by sensors to meet the different needs of different users and discover new application fields and modes.
