The third wave of global information industry: things, thing things
A. Things definition, principles
Things concept which is defined as: radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners and other information sensing device, according to the agreement, to any article connected to the Internet, communication and exchange of information, in order to achieve intelligent identification, location, tracking a conceptual network monitoring and management.
The principle of "Things" refers to a new technology mutual convergence of various types of sensors and the existing "Internet." Things computer is based on the Internet, using the RFID, wireless data communication technology, a cover configured to everything in the world of the "Internet of Things". In this network, objects (goods) to conduct an "exchange" with each other without human intervention. Its essence is the use of radio frequency identification (RFID) technology, to achieve interconnection and sharing goods (products) and automatic identification information through the Internet computer. And RFID, it is a technology that allows "speak" items. In the "Things" in, RFID tags are stored specification information having interoperability, to collect them automatically to a central information system through a wireless data communication network, identify the item (product), and then through an open computer network information exchange and sharing, to achieve the objects of the "transparent" management.
Second was the case of networking related technologies:
1. The perception layer technology
Perception layer data acquisition and perception mainly used for collecting data and physical events occur in the physical world, including various types of physical quantities, logos, audio and video data.
2. Network layer technology
The network layer to be able to perceive the information accessibility, high reliability, high safety performed, requires the sensor network and the mobile communication technology, the internet technology integration.
3. Application layer technology
Application layer consists mainly sub-layer application supporting platform and application services sub-layer. Wherein the sub-layer application support platform for supporting cross, cross-application, cross-system information collaboration between the shared interworking function. Application server sub-layer, including industry application of intelligent transportation, smart healthcare, smart home, smart logistics, smart electricity.
4. Public Technology
Public art Public art does not belong to a particular level of networking technology, but things have a relationship with the three-tier architecture technology, which includes the identification and analysis, security, network management and service quality management
