1, the Internet of Things (Internet of Things, IoT) is through a variety of information sensors, radio frequency identification technology, global positioning system, infrared sensors, laser scanners and other various devices and technologies, real-time collection of any need to monitor, connect, interact with the object or process, to collect its sound, light, heat, electricity, mechanics, chemistry, biology, location, and other kinds of information needed. Through the Internet will be a variety of devices (such as sensors, smart phones, etc.) connected to realize the intelligent interconnection of things, people and things, data *** enjoyment and interoperability of the network system

2, the Internet of Things (IoT, Internet of things) refers to "everything connected to the Internet". Through RFID (RadioFrequency Identification, wireless radio frequency identification), inductors and other information sensing equipment, according to the agreed protocols, the items and the Internet connection, information exchange and communication, in order to realize the intelligent identification of the items, positioning, tracking, monitoring and management

3, the Internet of things layered

The Internet of things can be divided into sensing, transmission. Internet of Things can be divided into perception, transmission. Platform, application four layers. Platform layer mainly contains communication vendor platforms including ctwing, China mobile onenet, etc.; Internet vendor platforms including ali cloud, jingdong cloud, millet, etc.

4, IoT industry characteristics

Connectivity: IoT through the Internet will be a wide variety of devices (eg, sensors, smartphones, etc.) to connect, and to achieve the data *** enjoyment and interoperability of the network system

Intelligent: IoT can realize intelligent interconnection between devices, automate management and operation, improve production and life efficiency, and reduce costs.

Global: IoT covers a wide range of areas, allowing information to be exchanged and ****ed globally.

Real-time: devices in IoT can monitor, collect and process data in real-time, supporting real-time control and decision-making.

Security: IoT needs to ensure data security during data transmission and storage to prevent malicious attacks and external intrusion.

Openness: IoT devices can interact with other devices or cloud applications through public **** interfaces to achieve openness, flexibility and interoperability.
