The Design And The Implementation Of An EPC-based Information System

EPC network is based on the Internet, radio-frequency identification technique and wireless communication and aims to structure the "Internet of things" which can share the information of global product in real time. EPC network is researched and applied more and more widely, including the hardware research on tag and reader, the research on EPC network software, the research on the field concerning with E-commerce. The paper, based on the study on EPC critical technique, researches the system architecture and the implementation of EPC network, designs and realizes the EPC-based information systems.The EPC system infrastructure is the basis and premise to build the EPC-based information system. Thus, this paper, applying the middleware-based approach to integrate the key functions of EPC network integration module, focuses on the composition of EPC network and the implementation of key techniques. This paper designs and implemented the ALE middleware in accordance with the EPC Global ALE1.0 standard.This paper analyzes the potential security problems of the EPC-based Information System, puts forward the Trust EPC System Model based on light weight PKI. In accordance with the Enterprise Trust and Collaboration Model, the search algorithm of the trust corporate relations between the different EPC System, the paper proposes an effective solution to the EPC System information interaction about the authentication and authorization security issues.This paper developes the EPC integration architecture using the SOA, publishes the core services of the reader middleware ,the filtering and collecting middleware (ALE) and the EPC enterprise information interaction middleware to the SOA service bus,users can call on the bus service to use the functions of EPC system. Based on the EPC service bus, this paper, combining the demand of the information of supply chain management in a specific 4S car store, designs and realizes an EPC-based information system.
