The Internet of Things, known in English as Internet of things (IoT), as the name suggests, is the Internet of things connected to things.
This has two meanings:
1, the core and foundation of the Internet of Things is still the Internet, a network that extends and expands on the Internet;
2, it extends and expands from people to any item to item, to exchange information and communicate, that is, things are connected.
Devices do not need any artificial interference between each other to communicate with each other to form a network of devices, the device itself can complete the creation, modification, deletion, sending and receiving data, and use that data to make decisions. So the key to the IoT is the exchange of data between devices.
The application areas of IoT include the following: transportation and logistics field, industrial manufacturing, health care field range, intelligent environment (home, office, factory) field, personal and social fields, etc., which has a very broad market and application prospects.
Expanded Information:
p>The principle of the Internet of Things technology is actually based on the computer Internet, the use of RFID, wireless data communications and other technologies, to construct a world covering tens of thousands of buildings "Internet of Things".
In this network, the building (items) can "communicate" with each other without human intervention. In essence, the use of radio frequency identification (RFID) technology, through the computer Internet to realize the automatic identification of goods (commodities) and information interconnection and **** enjoy.
The core technology of the Internet of Things is still in the cloud, cloud computing is to realize the technical core of the Internet of Things.
The three key technologies and areas of the Internet of Things include, key technologies: sensor technology, RFID tags, embedded system technology. Areas: public **** affairs management (energy saving and environmental protection, transportation management, etc.), public social services (medical and health, home construction, finance and insurance, etc.), economic development and construction (energy and power, logistics and retail, etc.).
Sensor technology is a key technology in computer applications, transforming analog signals in transmission lines into processable digital signals that are handed over to computers for processing.
RFID, known as Radio Frequency Identification, that is, radio frequency identification technology, is a kind of radio frequency technology and embedded technology into a comprehensive technology, in the near future will be widely used in automatic identification, goods logistics management.
Embedded system technology is a kind of computer software, computer hardware, sensor technology, integrated circuit technology, electronic application technology integrated into one of the complex technology.
