Research And Realization Of Information Service Capture Mechanism In EPC Network

Internet of Things is another wave of revolutionary global information industry after the invention of computer, the development of Internet and mobile communitication network. EPC network provides supports for Internet of Things. As the core module of EPC Network the Information service provides data exchange services for Internet-based enterprise heterogeneous applications and provides data query and data capture to achieve RFID data sharing in EPC Network. Many of today's domestic and foreign institutions conducted a study of the capture mechanism and design in the Information Service of EPC Network. However, these studies are not mature at this stage, and not with the practical application of the combination. As for the practical applications of enterprise have a high demand of data sources security and processing power, so the capture mechanism should be designed to have high security and reliability, but existing studies for the capture process did little discussion of these issues. This paper focuses on these issues and makes a study of information service catpure mechanism in EPC network.In this paper, based on in-depth research and analysis on the information service catpure mechanism in EPC network, we focused on the study for the following three aspects: First, according to EPC Information Services requirements for system reliability, we design data capture engine, the data validatation and the persistence technology ensures the reliability of services. Second, the notification mechanism has been designed to guarantee the communication with other platforms in EPC network and to guard the exceptions in capture. Furthermore, the design of the integrated management platform provides a unified platform for information management and maintenance services for information service in EPC network.This paper first introduces the background and current situation of information service in EPC network, analyzes the EPCglobal's EPCIS specification and the major domestic and international information services infrastructure, and then summarizes the requirements for capture services and current research problems Secondly, this paper shows the architecture of information service capture module and a detailed description of the design of all components, including data source access layer, capture service layer, information notification layer, management layer, and capture access control. After that we describe the concrete implementation of the various parts of the system and make a demonstration of system running. At the end of the paper, we summarize the entire paper, look forward to the prospect of information service capture mechanism and propose some future works.
