摘要：Internet of Things of course build a very good blueprint, but the current global situation to the development of things facing many problems, such as the Internet of Things, you must first memory bank to embed electronic tags on all items, and need to install a number of read equipment and a huge amount of information processing system, which will inevitably lead to a lot of capital investment. The items attached storage will lead to the rise in cost of goods, cost has not yet dropped to the popularity of the premise, the development of the Internet of Things will be limited.

chnology is not complicated: the label into the magnetic field, receiving the RF signal emitted by the reader, by virtue of the induced current energy to send out product information stored on the chip (passive tags or passive tags), or active to send a frequency signal (active tags or active tags); readers to read and decode the information sent to the central information system for the data processing.
(2) RFID technology standard outlines
RFID technology standards developed by ISO and IEC. Currently available to the RF card of several radio frequency technology standard ISO/IEC10536, ISO / IEC 14443, ISO / IEC 15693 and ISO/IEC18000. The most widely used is the ISO / IEC 14443 and ISO/IEC15693, the two standards are the physical characteristics, radio frequency power and signal interface, initialization and anti-collision and the four components of the transport protocol.
2.2.2 WSN
(1) Introduction of WSN
WSN is a wireless sensor network; short for wireless sensor networks. The sensor network will be able to expand the capacity of people with the real world for remote interaction. Wireless sensor network is a new information access platform, real-time monitoring and collection of a variety of detection of objects in the distribution network within the region, and this information is sent to the gateway node in order to achieve the specified range of target detection and tracking, rapid deployment, anti-survivability characteristics of strong and has a broad application prospects. Business Week and MIT Technology Review reports predict future technological development, wireless sensor networks as the 21st century's most influential 21 technology and change the world, 10 technical one.
(2) WSN network structure
WSN network is usually divided into the physical layer, MAC layer, network layer, transport layer, application layer. The physical layer defines the physical parameters of communication in the WSN, which band, which signal modulation and demodulation. The MAC layer defines the initialization of each node, by sending and receiving beacons, request, and associate the message to complete their own network definitions, and debug strategy of the MAC frame defined at the same time, to avoid communication conflicts between multiple transmitting and receiving nodes. At the network layer to complete the logical routing information collection, send and receive network packages able to follow a different strategy, using the most optimal path to reach the target node. The transport layer provides the reliability of the parcel transfer; provide access to the application layer. The application layer will eventually integrate the collected node information processing, to meet different application needs.
2.2.3 Intelligent Technology and Nanotechnology
Smart technology is to achieve some intended purpose to use the knowledge used in a variety of ways and means. Intelligent system implanted in the object, can make objects with a certain intelligence can be active or passive communication with the user, is also one of the key technologies of the Internet of Things.
Nanotechnology is the study of the structure size within the range of 0.1 to 100 nm. Nature of the material and application, the advantages of nanotechnology means that smaller and smaller objects in the Internet of things which can interact and connect. Current trends in electronic technology devices and systems small
