The Internet of Things English name is things. The core and foundation of the IoT is still the Internet, which is an extension and expansion of the Internet on the basis of its client-side extension and expansion to the exchange of information and communication between any goods and goods. Therefore, the definition of the Internet of Things is through the radio Frequency identification (RFID), infrared sensors, global positioning system, laser scanners and other information-sensing equipment, according to the agreed Protocol, the connection of any object to the Internet, information exchange and communication, in order to achieve intelligent identification of items, positioning, tracking, monitoring and management of a network ...

The Internet of Things, also known as the Sensor network, is another wave of information industry following the computer, Internet and mobile communication network. Everything in the world, small to watch, key, big to the car, building, as long as embedded a micro-sensor chip, it becomes intelligent, the object can be "automatically open to talk." With the help of wireless network technology, people can "talk" with objects, objects and objects can also "communicate", this is the internet of things.

The scene in the film, through the "Internet of things" gradually realize and upgrade, everyone's life will be closer to this. The so-called Internet of Things, also known as the Sensor network in China, refers to a huge network of information-sensing devices combined with the web.

There are three levels of IoT systems:

Second, the network layer, through a variety of telecommunications networks and the integration of the Internet, the object of information in real-time and accurate transmission;

Third, the application layer, the perceptual layer of the information to be processed to achieve intelligent identification, positioning, tracking, monitoring and management and other practical applications.

IoT key technologies include: RFID, short-range wireless communications, IPV6, cloud storage, cloud computing, cloud services, QR codes, sensors, etc.

Internet of things Application layer:

Providing rich IoT-based applications is the fundamental goal of IoT development;

Combining the Internet of things technology with the needs of industry informatization to realize a wide range of intelligent application solutions;

The key lies in the integration of the industry, the development of information resources, low-cost and high-quality solutions, security of information and effective business models.

IoT Network layer:

The widely-covered mobile communication network is the infrastructure to realize the internet of things;

It is the most standardized, most industrialized and mature part of the Internet of Things (IoT) level three.

The key is to optimize and improve the application features of the Internet of Things to form a network of synergetic perception.

IoT-aware layer:

Perceptual layer is the core ability to realize the comprehensive perception of IoT;

It is a part of the Internet of things that includes key technology, standardization and industrialization.

The key is to be more precise and comprehensive, and to solve the problems of low power consumption, miniaturization and low cost.
