Description

METHOD AND SYSTEM FOR AUTOMATICALLY I / O-PORT LINKING FRAMEWORK FOR THE MODEL-BASED DESIGN IN BLOCKS DIAGNOSTIC ENVIRONMENT USING THE CLOUD CONCEPT Based Design < RTI ID = 0.0 >

The present invention relates to a model-based design technique. More specifically, a developer of each model develops a model faithful to input / output of a design element, and a system designer selects an arbitrary model from a model server, The present invention relates to a method and system for automating input / output port connection between each model.

Model based design basically has advantages in reusability and modularity of each model. System designers sometimes need to find the optimal design point to increase the efficiency of the overall system and achieve the goal by changing the design element for the part even if the expertise of each model is not enough. In a block-diagram-based model-based design platform, this task is very advantageous, but at least the process of I / O port connection between models is necessary and it is not easy.

To determine the impact of each model design element on the overall system in a typical system design, the system designer needed the capability of a system engineer to understand the entire system and implement it directly, or to separately integrate the system. This leads to a contradiction in the process of finding the optimum design point to maximize the efficiency of the entire system rather than designing another system.

In other words, it is very inefficient in terms of cost and time because the whole system needs to be newly dealt with in order to check the effect of the single-system-level model design change.

Hereinafter, a method and system for automating input / output port connection between each model using a cloud concept in a model-based design in a block diagram environment according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a conceptual diagram illustrating a port cloud database (DB) registration structure of a model in a model-based design platform according to an embodiment of the present invention. Referring to FIG. 1, any model-based design platform 100 utilizes a cloud system to manage the output ports of each model. The cloud system is a network concept that enables each information subject to access any information subject without having to own or distribute the information and all the information exists in the virtual space. When this is applied to the input / output port connection of the model, all port information exists in the virtual space, so that arbitrary models can access the port cloud information and automatically connect between the models.

The model-based design platform 100 consists of a port cloud database 101 and a registered model database 102. In addition, the model-based design platform 100 may include a block diagram environment simulation framework and the like. When the models 111, 112 and 113 are initially registered, the model output port information (for example, modelA.out1, modelA.out2, ..., modelB.out1, modelB.out2, ..., modelC.out1, ) Are automatically registered in the port cloud database 101. [ The output port information includes connection input port information (121, 123, 125) and connection output port information (122, 124, 126). 1, the connection input port information of model A 111 is in1, in2, in3, the connection output port information is out1, out2, the connection input port information of model B 112 is in1, in2, The connection output port information is out1, out2, the connection input port information of the model C113 is in1, in2, in3, in4, and the connection output port information is represented as out1.

2 is a conceptual diagram showing a port cloud DB and a model input port connection structure using a port cloud registration management user interface (UI) 103 in model registration according to an embodiment of the present invention. 2, the model output port information of each model is automatically registered in the model-based design platform (100 in FIG. 1) by the cloud system and input from the port cloud database 101 through the port management program You can assign and / or connect output ports to ports.

In particular, FIG. 2 shows an example in which model output port information to be connected to the input port of the corresponding model is selected from the port cloud database 101 when the arbitrarily changed model is uploaded to the model-based design platform (100 of FIG. 1) It shows the process of becoming connected with the output port of the diagram.

An arbitrary model acquires necessary information (input port) or provides (output port) by connecting each port to a corresponding port of another model through a port cloud database. The matching between the connection input port information of the model database and the model output port information in the port cloud database can be modified by the system designer and / or the model based design platform user.

The port cloud registration management user interface 103 is configured in a terminal such as a computer, a notebook, and the like, and is a management tool for establishing and managing a connection between the port cloud database 101 and an arbitrary model input port.

3 is a connection example (104) of inter-model input / output ports according to the port cloud database connection setup shown in FIG. In particular, FIG. 3 shows a structure in which an arbitrary model is connected to another model in the system. The input ports (in1, in2, in3, in4) of one model C (113) are connected to the model A ( 111 and the output ports out1, out2 of the model B 112, respectively. The automatic connection structure 131 shows this connection.

The connection between the I / O ports through the port cloud database is performed when the characteristics and naming are matched by the predefined definitions between the designers, thereby increasing the reliability of the system construction. For example, suppose you are designing an airplane system in a block diagram environment. There may be sub models in the system such as a wing drive model, an engine model, and a motion model of a flying body. Airplanes are complex systems, and there are many sub-models in addition to the models listed above. Airplane systems and sub-model designers share the development environment in the block diagram and can define / share rules for naming and characteristics of each model in the following form.

" Type of model " _ "Identifier (character or number) according to version" _ " Input or output delimiter" _ "Port identifier (character) "

In the above definition, the type of the subsystem to which the model corresponds is defined through the "type of model", and the characteristics of the input / output signal can be determined through the "port identifier (character)".

For example, in the case of design version A1 among the wing drive models of an airplane system, one of the output ports can have a wing drive angle and can be defined as follows.

Wing drive model _A1_OUT_ wing drive angle

The wing-driven model output port above can be connected to the input port of the vehicle motion model, and the input port of the vehicle motion model design version B1 can be defined as:

Motion model _B1_IN_ wing drive angle

The wing driving angle information that the motion model should receive as input through the above rule can be provided from the output port including the wing driving angle information among arbitrary models.

The above example is not limited to a specific system but may be applied to any system on the same principle.

It also provides a model-based design architecture in which design flexibility and / or efficiency of the entire system is increased as designers and model-based design platforms for each connection are given the design freedom of users.

On the other hand, an arbitrary model is uploaded to a model-based design platform (100 in FIG. 1) by designing according to predefined input / output and appropriate engineering procedure between designers without information of other models. I / O information is set according to the type and item defined at the time of naming the input / output port. The design according to the engineering procedure is to solve the engineering equation (equation of motion or state equation) using the information obtained from the input port of each model And the output information is generated according to the algorithm in the model.

Therefore, the cloud system can be connected to an appropriate location in the system by its own input / output port information and port cloud database information, and can play a role as a sub system.

This feature lowers the occurrence of human errors that may occur with existing designs, and minimizes unnecessary port creation and connections, since promised I / O requirements are checked naturally.
