The present invention relates to a method for exchanging data between heterogeneous systems to support the system and a system for the same.

As most companies are actively introducing commercial PDM / CAD systems, problems related to information exchange and management between existing CAD systems and PDM systems, heterogeneous PDM systems, or heterogeneous CAD systems are occurring.

In order to solve the above-mentioned problems, research on international standards and supporting systems is required to smoothly exchange data between heterogeneous systems.

Meanwhile, in the 1980s, there have been efforts to exchange data by defining a standard neutral format for exchanging shape information between CAD systems in foreign countries.

STEP is an international standard financed by ISO, a standard-neutral format that serves as a common language used by manufacturers to exchange product information between different automation systems when developing and producing products. The Initial Graphics Exchange Specification (IGES) The case has been developed since 1980, focusing on the exchange of various shape information.

Consortium for Advanced Manufacturing International (CAM-I) is an international industry research institute in Texas, USA, that has established a feature taxonomy to define standardized data representations of manufacturing processes. 1 is data showing a part of the constructed feature classification system.

Here, the feature classification system is to classify and define the feature shapes that should be used for each domain, and build up the system.

However, most of these studies have been developed with a focus only on the exchange of product information and configuration information, so there are many areas to be supplemented for information exchange and management between PDM systems.

The present invention has been made to solve the above-described problem, in order to exchange product information between heterogeneous PDM system and CAD system, extract the necessary information from each PDM / CAD system and generate a neutral file for information between heterogeneous systems There is a technical problem to provide a method for exchanging data between heterogeneous systems and a system therefor to enable exchange.

As shown, the data exchange system 200 is connected to another system (eg, a PDM (Product Data Management) system, a Computer Aided Design (CAD) system, etc.) 100 through a communication network, from each other system. It extracts data using API applicable to the system and creates and manages it as PLM Services based neutral file to support data exchange between heterogeneous systems.

Here, PDM is a concept to achieve overall engineering efficiency improvement by integrating and managing all tasks and information throughout the life cycle around the product.

On the other hand, the PDM system refers to a data management system that integrates and manages all data related to product development and manufacturing, such as design, manufacturing, sales, and after-care in product planning. Of course, it manages all the data necessary for each step in the product development and manufacturing process such as plan, shape model, CAD drawing, image, NC program, and performs data security and access, data integrity maintenance, management, and various notification and message functions. do.

In addition, PLM Services was developed by the XPST (eXtended Product Data Integration) team of the ProSTEP iViP Alliance and is a data exchange standard adopted by the OMG (Object Management Group) in 2004.

PLM Services' data model follows the structure of STEP 214, which is a good representation of the structure of product data used in the automotive industry. In particular, since it is web-based and represented in XML, in terms of data exchange through middleware Superior to STEP In addition, it defines a platform independent model (PIM) model that is not affected by the platform, and it is defined to be executed and accessible according to various standards such as STEP, XML, UML, SOAP, and WSDL.

In addition, PLM Services is structured to act as a server in connection with various PLM solutions such as ENOVIA, Winchill, Teamcenter, etc. It is designed to be flexible and easy to access and manage.

On the other hand, CAD is a software technology that performs various design / design planning, drawing, modification, analysis, etc. optimally using a computer, and builds a database to quickly and accurately handle all aspects of design work. It is applied not only to the design / design field but also to the production, logistics, and sales. In other words, it connects the entire process from the basic conception stage of styling to the production phase, CAM, logistics management, and POS system, and displays the data necessary for design / design by using the computer's data processing capability.
