Description

System and Method of tracing quality of the object on EPC global network}

The present invention relates to a quality tracking system and method on an EPC global network. More particularly, the present invention relates to an EPC global network for tracking and managing a product belonging to a defective product or an event related to a defective product through a quality tracking server on the EPC global network. A quality tracking system and method in the art.

In recent years, Radio Frequency IDentification (RFID) has been used in objects for the purpose of replacing bar codes. Recently, the EPC global Network shares object information and movement information between companies in the supply chain using Internet technology.

The conventional EPC global network consists of an electronic product code (EPC) code, a tag and a reader, a middle ware system, an object information server (EPCIS), and an object search server (ONS). In conjunction, information was obtained and shared on the EPC global network.

At this time, the information stored in the RFID tag attached to the object is composed of the manufacturer ID, product classification code, serial number, the data read by the reader is stored in the object information server existing in the institution.

Meanwhile, there is an Object Naming Service as a method of obtaining production information stored in an object information server installed in an institution producing a product. An Object Search Server that provides an object search service stores object information of each EPC. Contains the address of the EPC Information Services server.

When the object inquiry application receives a request from the user for information about a product associated with a defective product or a product belonging to an event associated with a defective product, the object search server asks the object search server for the address of the object information server storing the information of the object to which the EPC is granted. In order to obtain the address of the object information server, the object inquiry application accesses the object information server of the corresponding address and receives the product information.

In this case, for the history and tracking of the EPC on the supply chain, when an object moves between different networks, a separate device for integrating and managing logistics history information according to the movement of the object is required. However, in the conventional EPC global network system, only the necessity of introducing such a history information management device is recognized, but a specific solution does not come up.

In addition, the method of tracking EPC in EPC global network system will be the same for each user, and it would be inefficient to develop a tracking program for each user who performs the same procedure. In particular, tracking the history of a product by following the above procedure is not a complete traceability trace. Determining the event of the object information server for each business process is different for each business environment and designer. Therefore, an integrated tracking program must be developed by understanding and interpreting it.

On the other hand, when supply chains follow the Track & Trace framework of the EPCglobal network, there is no problem in tracking unit-of-interest units of interest, but the user is able to discover objects in a central repository, for example, an EPC global network. By knowing the location and interface of, you can easily know the address of the object information server to which the goods have moved. However, problems can occur when tracking the internal logistics flow of the object information server.

Referring to FIG. 1, when a parent relationship between a child EPC and a parent EPC is formed, as in the business step ②, after that, only the parent EPC may be recognized and only an event including only the parent EPC may be stored in the object information server. . In particular, in pharmaceutical logistics, when packaging a large amount of drugs with RFID tags in a box, the parental relationship is stored in the object information server, and the model recognizes only the RFID tags in the box until the package is disassembled and tracks the drug flow therein. to be.

At this time, the event related to item EPC to complete the point tracking (object information server address tracking) for the item EPC that the user wants to track through the discovery service and to track the internal logistics flow to the plant object information server. In the case of querying the plant object information server, the object event related to the item EPC and the aggregation event may be answered in the business steps ① and ②. Here, the item EPC was not stored as an event in the business step ③, but actually went through the business step ③. Therefore, the user should check whether there is a parent EPC with item EPC as a child element based on the result of the first query and then re-query to the point where the parental relationship is broken. This behavior is proportional to the depth of the parent-child relationship, and the problem arises that the number and complexity of queries on the inquirer side increases.
