The Internet of Things is regarded as the application expansion of the Internet, application innovation is the core of the development of the Internet of Things, and innovation with user experience as the core is the soul of the development of the Internet of Things. English name: Internet of Things(IOT), also known as the Internet of Things. Internet of things
The Internet of Things refers to the real-time collection of any object or process that needs monitoring, connection and interaction through various information sensing devices, such as sensors, radio frequency identification (RFID) technology, global positioning system, infrared sensors, laser scanners, gas sensors and other devices and technologies, and the collection of sound, light, heat, electricity, mechanics, chemistry, biology, location and other needed information, which is combined with the Internet to form a huge. Its purpose is to realize the connection between things, things and people, and everything and the network, which is convenient for identification, management and control.
Compared with the traditional Internet, the Internet of Things has its distinctive features. 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.
The meaning of "thing"
The "things" here can only be included in the scope of "Internet of Things" if the following conditions are met: 1, data transmission channel; 2. It has certain storage function; 3. there is a CPU；; 4. Have an operating system; 5. There are special applications; 6. Follow the communication protocol of the Internet of Things; 7. There is a unique number that can be identified in the global network.
Definition of Internet of Things
The Internet of Things is a network based on information carriers such as the Internet and traditional telecommunication networks, which enables all ordinary physical objects that can be independently addressed to be interconnected. It has three important characteristics: public object equipment, autonomous terminal interconnection and universal service intelligence. Internet of Things refers to ubiquitous terminal equipment and facilities, including sensors with "intrinsic intelligence", mobile terminals, industrial systems, building control systems, home intelligent facilities, video surveillance systems and so on. And "external enable". For example, "smart objects or animals" or "dust" such as various assets with RFID, individuals and vehicles carrying wireless terminals, realize cloud-based interconnection (M2M), big convergence, SaaS operation through various wireless/wired long/short distance communication networks, Provide safe, controllable and even personalized real-time online monitoring, position tracking, alarm linkage, dispatch and command, plan management, remote control, safety prevention, remote maintenance, online upgrade, statistical reports, decision support, leadership desktop (centralized display of cockpit dashboard) and other management and service functions, so as to achieve "high efficiency, energy saving, safety, environmental protection, safety, safety, environmental protection, safety,"
EU definition
In September 2009, at the "China-EU Symposium on Internet of Things and Enterprise Environment" held in Beijing, Dr. Lorent Ferderix, head of RFID Department of the Information and Social Media Department of the European Commission, gave the EU definition of the Internet of Things: the Internet of Things is a dynamic global network infrastructure with self-organizing ability based on standard and interoperable communication protocols, in which physical and virtual "things" have identity, physical attributes, virtual features and intelligent interfaces, and interface with information. The Internet of Things will form the future Internet together with media Internet, service Internet and enterprise Internet.
