Based On The Epc Internet Of Things Architecture Wireless Communication Protocol

EPC and the internet of things are new content in logistics industry. They aim to resolve information transfers mistakes such as information delay, distortion, exchange mistakes, etc, when utilizing the information technology to carry on the data interchange of the logistics. The internet of things which cover with every goods all over the world, is based on the internet, and realized through RFID technology, wireless communication technology and computer technology. Every goods has a only EPC(Electronic Product Code) within the internet of things. Genually EPC code is saved electronic tag, which consisted of silicon chip and antenna, often affixed on goods. The EPC can be identified, transmited and query by information service software.The service form the internet of things service.After describing the basic technology of the internet of things, this paper introduces the air interface protocol of RFID reader and tag in detail. And put forward a suggestion for this protocol.After that, this paper illuminate a RFID application project, which is a demo for electronic traffic collector in Shandong highway.In domestic, this is first time to describe technology of the internet of things and EPC. This is the first time to discuss the theory of communication protocol between reader and tag. Limited by the development of industry and capability of writer, this paper just made primary research of RFID air interface. There are lots of projects should be researched in the internet of things, both in technology and in management. I really hope this article is a good begin for subsequent researchers.
