Research And Design Of Open RFID Public Service Platform

RFID is an emerging identification technology, and is taking the place of barcode depending on its own advantages, and is playing a more and more important role in enterprises. With the penetrating and promoting of RFID application, RFID application becomes open application from closed application. This requires building some public data coding, exchanging and sharing standard architecture to meet enterprises and parties open application requirements. Thus, EPCglobal international organization combines RFID and Internet, and puts forward EPC Network, uses EPC to uniquely identify objects, and constructs an Internet of things. Further more, EPCglobal establishes a set of standards, in order to direct the construction and popularization of EPC network, and realize real-time information sharing of global things. At the same time, EPCglobal standards provide construction basis for national RFID public service system.Aiming at the open-loop and complex requirements of new situation's RFID application, this paper referenced on EPCglobal standard basic architecture, and researched an open RFID public service platform (ORFP) fitting for Chinese conditions. The platform had outstanding merits at the aspects of compatibility and carrying out ability.This paper first systematically introduced EPCglobal architecture standard, put forward the platform architecture, and made contrast between ORFP and EPCglobal architecture in detail. Then, the data support of public service layer—enterprise information service EIS was researched, and a scalable architecture was designed. Besides, EIS basic service publication specifications were established. Then, Aiming at the problem that the current coding architectures were chaos and hard to interact mutually, the layers structure of code resolving service CRS was put forward—"Root-Country-Industry", and the compatibility of CRS and other coding architectures was researched. Based on entirely analysis on existing discovery service methods, a central and distributed code discovery service CDS solution was put forward—a link discovery method based on extended EIS. This method stored product's moving information in distributed enterprise's EIS, thus it had the merits such as low cost, well commonality, well scalability high stability and high security. Aiming at the link-breaking problem, an enhanced CDS was researched, and ensured the stability of CDS. At last, key issues were analyzed and discussed such as the platform's security and efficiency improving methods.Based on the research results above, an ORFP prototype was designed, and performance test was carried out with SOAPUI. Test results showed the public service layer of ORFP had nice service efficiency, and further validated the platform's design.
