Reseachof Internet Of Things EPC System Communication Protocol

In today’s business, in order to reduce logistics costs, enterprises are in urgent needfrom the product identification and tracking supply chain optimization.The new supplychain solutions can be summarized as enterprises timely know the location information ofeach product at any time in their supply chain. So you need to have a technology that canidentify every product, and be able to quickly acquire the information of the product, butneed a system to manage the transfer of the enterprise or internal information.Auto-ID Center at the Massachusetts Institute of Technology was established in1999proposed the concept of the Electronic Product Code EPC (Electronic Product Code). Sincethen, the EPC has been widely studied, countries around the world and large companiesthrough the development of radio frequency identification standard, and use of networktechnology to the formation of the EPC network. EPC network on the basis of the computerInternet, the use of radio frequency identification, wireless data communicationstechnology, constructed a physical Internet, the core of the EPC and RFID tags based onRFID technology and EPC is a product is assigned a unique identification code, the RFIDintroduction of the logistics field was fast and accurate collection of data provides a goodsolution. Only stored in the EPC RFID tags, without storage products corresponding tospecific business information, so the EPC Information Services (EPC Information Servicethat is, the EPCIS) for the above program provides an effective solution: electronic tags tostore the EPC corresponding Business data storage to the EPC Information Service and canbe accessed by a product of the EPC to the corresponding EPC information Services.On the basis of the introduction of Things basic technical knowledge, this paperfocuses on the RF reader and tag air interface communication protocol, and multi-tagidentification of the anti-collision algorithm to do a certain amount of theoretical research.Finally, content and shortcomings of this study are analyzed, and made follow-uprecommendations of the study and outlook.
