Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In an embodiment, as shown in fig. 1 and fig. 2, there is provided a method for integrally constructing an avionics system primitive model, where the method includes the following steps:
s10, object information, relationship information, point information, attribute information, and character information are identified from the SysML graph model.
It should be noted that the models of all the fields established in this embodiment are instantiated from the lowest meta-model to the meta-model, and then instantiated. As shown in fig. 3, for the meta model layer, the linguistic characteristics of the model itself are described, that is, the most basic attributes in the model are identified and extracted, and are defined in a standardized manner. Therefore, the meta-model layer is generally a definition of a certain modeling language itself, and is a minimum composition unit of the model, like the definition of data types such as int float in the code; the meta-model layer effectively associates the definition identified by the meta-model layer to generate a modeled basic structure, and the structure contains a plurality of meta-models of different types; the model layer assigns a meta-model structure to a certain business property and assigns a meta-model structure to a specific value, so that the model is constructed in various types. The graph model is the most common model type for the overall design and demand analysis of civil aviation and electric systems, and the SysML is the most common language in the graph model.
The SysML graph model is a system modeling language that expresses the various features and states of a system in terms of requirements, structure, parameters, and behavior. The model based on the SysML language is mainly a graph model and can be divided into nine types of graphs: model definition diagram, activity diagram, parameter diagram, requirement diagram, sequence diagram, internal module diagram, package diagram and use diagram. The modeling method has the advantages that many elements such as requirements, scenes, functions, physics and the like in the design process of the avionic system can be expressed due to high flexibility, and the disadvantage is that the generality of SysML diagrams can not be used for special modeling of a certain characteristic service when the avionic system is modeled, so that a set of element model driven methodology is defined by disassembling and identifying diagram model elements based on SysML, an avionic system modeling integrated special element model library is established, and the rapid generation of an avionic system element model is finally realized.
Specifically, in this embodiment, the point information, the attribute information, and the role information are identified from the SysML graph model, which is specifically as follows:
SysML point information identification: corresponding point elements are found out by analyzing the SysML image model, and the common point elements in the SysML comprise various interfaces in the module, such as a proxy interface, a complete interface and the like; points are generally considered to be encompassed in the definition of an object, and therefore the definition of a point generally needs to be completed before the object is defined;
the SysML attribute information identifies: identifying attribute information in the SysML model, wherein the attribute information is multiple attributes such as a value attribute, a stream attribute, a composition attribute, a reference attribute and the like in the model, the attribute is generally included by a relation or an object, and the attribute needs to be defined before the relation or the object is defined;
SysML role information identification: the roles in the SysML model are identified, the roles are bound at two ends of the relationship, and the roles define the characteristics of the relationship between the source and the end object, so the definition of the roles needs to be completed before the object relationship in the model is defined.
Based on a construction method of a meta-model, six types of basic attributes of the meta-model are established: and (3) associating the six meta-models by expanding the additional constraint so as to construct a domain-specific meta-model library. The six meta-model classification is based on the following, where Extension refers to an additional constraint for building the meta-model.
FIG. (Graph): a set of objects, relations and roles is used for describing the connection relation among the objects, relations and roles, for example, nine graphs, a module definition graph, an activity graph, a parameter graph, a requirement graph and the like exist in SysML;
object (Object): classes have many attributes that are used to express an existing object. Relationships can be symbolically expressed, such as modules, requirements, states, and packages in SysML, all defined as object properties;
relationship (Relationship): a connection between two or more objects. Relationships cannot exist independently of objects, objects have many attributes, and relationships can be symbolized, as defined by the inclusion, association, combination, generalization, etc. in SysML.
Role (Role): the role is used for connecting a component and a relation, after the relation connection instantiation in the SysML is analyzed, corresponding initial end and terminal declarations are respectively bound with which objects and points in the relation, for example, the interface realizes that the initial end of the relation is a realization part, the terminal is a contract, and the initial end of the relation is used as a client terminal and a provider.
Point (Point): the symbolic representation of a character, a point cannot exist independently of an object, and a point may have many attributes. Stream interfaces and proxy interfaces as in SysML are defined as points.
Property (Property): attributes are used to define and describe the properties of some meta-types (objects, roles, points and relationships). Values, flows, constraints, compositions, operations, and references, etc., as in SysML, are defined as graph attributes.
The elements in the above meta model and the SysML graph model are corresponded as shown in table 1 below:

e) adding points of object attributes, introducing established points from a point library to the object attributes, setting the direction of the points to be selected, wherein the direction comprises three types, input, output and undirected, and returning to the step of point construction to reestablish the points if the added point library cannot be found in the point library;
f) adding the attribute of the object, introducing the attribute from the constructed graph attribute library as the attribute of the object, and returning to the step of constructing the graph attribute to reestablish the graph attribute if the added graph attribute cannot be found in the graph attribute library;

The instantiated model component of an object allows the corresponding section to be viewed as multiple instantiated graph models. In the profiling setup process, the profiled primitive models are selected as all the primitive models that have been created. When configuring, a plurality of primitive models can be configured for the section of an object, and after instantiation, the number of the section is not limited.
