Design And Implementation Of A Prototype System Of Epc Network Information Services

In order to promote the development of Internet of Things, EPCglobal established EPC information service standards, The EPCIS (EPC Information Services), complied with the EPCglobal standard, plays a very important in the EPC Network The role of the core information service system of things. With the rapid development of EPC network, a variety of sensors and readers, such as RFID (Radio Frequency Identification) technology has been widely used in the enterprise. At the same time, to participate in the enterprise networking has increased, including suppliers, retailers, third party logistics and other roles, each company will have its own EPCIS system, there will be data communication between each other, and each of enterprise systems large differences between the need to achieve a standard of communication data. However, at present there is no information service prototype system of things, you can a lot of real-time processing of the incident report, but different companies collaborate to complete the data exchange partners, which greatly hindered the application of networking technology in the enterprise information system.Combining EPCglobal EPCIS standard system conducted in-depth research, combined with practical application scenarios, designed and implemented a prototype system. The prototype system to commodity suppliers, retailers, business model as the background, providing a merchandise ordering, sales management and sales automation services results back, divided into EPCIS system, ONS system and push service three modules. EPCIS system receives lower ALE (Application Level Events) system to send over the incident report and provide query capabilities can handle four EPCIS events currently defined in the standard, namely Object Event Aggregation Event, Quantity Event and Transaction Event. ONS system serving as the basis for the entire information service system, mainly used to find the corresponding EPC EPCIS server address; push service is an innovative point of the prototype system, which is based on Web service standards, with the ability to effectively improve the data communication between the EPCIS system Through real-time data push handle a large number of label information sent.EPC network information service prototype system implemented in this paper, not only shows the EPC network application practice in the actual production, and through the use of Web services to build a loosely coupled application environment to achieve the data communication between heterogeneous systems business. The test results show that a significant push service improves the efficiency of processing large data EPCIS system for construction and performance optimization of great reference.
