DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a data-centric interlocking design technique for eliminating dependencies by inter-component interworking according to an embodiment of the present invention. Most distributed systems, including existing operational control devices, are configured through interworking between independent nodes and nodes. Components in the same node need to be interworked with each other within the node, and interworking between nodes should be defined separately according to the role of each node.

However, one embodiment of the present invention excludes dependencies that may be caused by the node configuration through direct linkage between the smaller units of components. Also, in order to exclude the dependency caused by the component to be interlocked, the interlocking structure based on the data is applied even when the components are interlocked.

It defines only the data types that are supplied / received from defining the data formats to be received / received and the objects to be exchanged in the existing interworking design, and the data exchange between the components is based on the communication model of the publish / subscribe method.

Referring to FIG. 1, a common component 120.130 is a constant component that each node is common and essentially required. The first common component 120, the second common component 130, and the like. The functional components 141, 142, 151, and 152 are components that can add functions. A 1-1 second functional component 141, a 1-2 functional component 142, a 2-1 functional component 151, a 2-2 functional component 152, and the like.

These common components 120 and 130 and the functional components 141, 142, 151, and 152 are interlocked around the common data. That is, a communication model of a publish / subscribe method is used through the common data model 110.

A publish / subscribe communication model refers to a publisher that issues and transmits exchange data to be exchanged, and a subscriber receives such exchange data. In other words, any one of a plurality of nodes (not shown) becomes the issuer, and the remaining nodes become the subscriber to transmit or receive exchange data.

Examples of components include an application of a large-scale application (abbreviation of an application), a generation-grade application, an external application, and the like. That is, large-scale applications and age-related applications become common components, and external applications can be functional components.

Of course, the communication unit (not shown) may be implemented by wire and / or wireless. The communication network is composed of a public switched telephone network (PSTN), a public switched data network (PSDN), an integrated services digital network (ISDN), a broadband ISDN (BISDN), a local area network (LAN), a metropolitan area network (MAN), a wide area network (WLAN), and the like. However, the present invention is not limited thereto, Access, Wideband Code Division Multiple Access (WCDMA), Wireless Broadband (Wibro), Wireless Fidelity (WiFi), High Speed Downlink Packet Access (HSDPA) networks and bluetooth. Or a combination of these wired communication networks and wireless communication networks.

Of course, one embodiment of the present invention will be described as a high performance network communication network such as a LAN.

FIG. 2 is an example of coding showing an Extensible Types based data model design technique for extending a data model according to an embodiment of the present invention. Referring to FIG. 2, an extensible type is an OMG (Object Management Group) standard for extension of common data to be provided / received between the components.

As shown in FIG. 2, not only the type of the information included in the message (that is, the message format) but the identification information @Id for identifying each information is added. In some cases, new information needs to be added to existing data formats due to system upgrades or new functions. In this case, new information may be added or changed in specific messages. At this time, it affects all components that receive / receive the message. However, when the extensible type is applied, not only the simple data type but also information for identifying the information included in the message is included, so that the existing component can be used as it is for adding new functions.

In an embodiment of the present invention, a data sharing service (DDS), which is a communication middleware supporting an extensible type, can be utilized for interworking between operation control device components. In addition, a method of adding identification information to each piece of information included in a received / received message can be applied.
