Research on key technologies and application of Internet of Things

Three parts such as: EPC middleware, ONS and EPC Information Service were studied in depth in this paper. And an EPC Middleware System, an ONS system, an EPC Information Service system were designed and implemented. Thus more complete information network system has been established, which provides a platform for "Internet of Things" rapidly extended to the enterprise and information-sharing among enterprises. EPC middleware system is a link between RFID equipment and enterprise applications.It provides connections to RFID equipment, puts EPC information into networks, checks EPC, filters EPC, bufiers EPC, etc.ONS system finds out the addresses of EPCIS servers through pretreatsintg EPC, and sends the addresses to EPC middleware. EPCIS system accesses to the corporate databases, provides externa services for quering item information. Finally in laboratory, a simulation platform was set up , and it verified the easibility of system.the test results show that EPC middleware, when it\´s work parameters has been adjusted according to the environment, can quickly, accurately eliminate redundancy brought along by dumb readers. EPC Information Server can accurately, safely return information of items.
