Abstract. This paper analyzes the importance of energy management technology in cold chain logistics, and how to establish the energy management system and it's saving strategies, combined with the trend of Internet of things (IOT) technology. This paper briefly introduces the system structure and related technologies of Internet of things, and the system framework, and key technologies of the energy management system of cold chain equipment based on Internet of things. In term of IOT, the energy problems can be significantly solved by using the cold chain energy management system.

Abstract. At present, there are four typical integrated models of RFID and WSN, which have some advantages while they have been integrated. To solve these problems, an optimized model is proposed, and a new dynamic RFID-WSN integrated system is designed based on the optimized strategies. The system is composed of a new integrated node, which is designed based on WSN network model and RFID protocol and can dynamically switch roles between WSN node, RFID reader and RFID tags. Through the design of dynamic construction mechanism to organize and manage these integrated nodes, the system realizes dynamic switching and adaptive construction between RFID and WSN. The new integrated system solves the problems existing in the four typical models and has better characteristics and more flexible applications.
