1.1 The concept of internet of things as the name suggests, is the substance of internet of things and was subjected to an Internet connection. He is the extension and expansion of the network based on the Internet, and its extension and expansion of the client to any goods and items. But internet of things itself is not only a tool for the transmission of information in its internal network to be able to collect data fusion, and ultimately transmitted to the user is the result of a large number of fusion of the final data.

Internet of things core technology includes a variety of sensor technology and electronic information transmission technology, access to and transmission of information items through these technologies, and give them real-time, large-scale tracking, positioning, and management, in addition to a variety of data fusion technology through the as a large number of data processing, and ultimately increase user awareness of the goods, and provide users with intelligent decision support.

1.2 The concept of smart grid smart grid refers to intelligent power grid, intelligent reflected in general through advanced sensing and measurement technology, advanced equipment and technology, advanced control methods and advanced decision support systems technology to improve energy efficiency improve security of supply, saving electricity costs, thereby improving the overall efficiency of the grid. Such a power network, which we call the smart grid. Features include smart grid include:

• Has strong healing ability, it can automatically detect faults and can quickly solve the grid, reduce outage time and economic losses;
• The increase in electricity price transparency, so that consumers can choose the appropriate power supply side;
• Improve the ability to resist attack power grid, improve security;
• Improve power quality;
• Can accommodate a variety of forms of power generation and storage;
• Reduce network operation and maintenance costs.

　　2. Internet of things technology in the smart grid

Internet of things have been all over every corner of people’s production and living, intelligent industry, intelligent agriculture, intelligent transportation, logistics and other fields have intelligent networking technology was applied. Internet of things are also used in smart grid ICT development to a certain stage the inevitable result of networking technology in communication, information, sensing, automation and other technology communication infrastructure, resources and power systems infrastructure resources for effective integration; matter various intelligent networked sensing devices to improve the level of information power system to achieve safe and reliable transmission of information and provide intelligent decision support, improve power system efficiency of existing infrastructure for grid power generation, transmission, substation, electricity, distribution and other sectors to provide important technical support. Application of networking technology to optimize the grid operation and management, improve reliability, efficiency and service level management of the grid.
