Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing to the present invention
Embodiment is described in detail.
Embodiment of the method
In order to improve the working efficiency of train exploitation design, manpower, fund and time cost, the present inventor are saved
Construct a kind of meta-model based on train technical demand.Wherein, complete or collected works' data of the train composition tree pre-established, institute are obtained
Train composition tree is stated to establish to obtain based on the structure of the train, for example, train composition tree as shown in Figure 1, in train composition
The relationship between superior and subordinate in train composition between all parts is presented in tree.Different type of train corresponds to different train knots
Structure, different train compositions correspond to different train composition trees；Using complete or collected works' data of the train composition tree, institute is successively chosen
Each system point in train composition tree is stated (for example, as shown in Figure 1, a system point in train composition tree corresponds to train knot
A component in structure), and respectively as the object in each meta-model；Each member is followed successively by from the demand library pre-established
Object select technical need in model, and as the demand in each meta-model；According to the object and need in each meta-model
Seek the relationship in successively determining each meta-model, the relationship in the meta-model includes relationship between object and object, object
At least one of the relationship between relationship and demand and demand between demand；According to determining object, demand and relationship
Successively establish each meta-model；Each meta-model of foundation is saved and constitutes metamodel data library in the database, the member mould
Type database is used for when receiving the instruction for calling the meta-model, and response calls the instruction output of the meta-model corresponding
Metamodel data is to construct the technical needs of all parts in train composition.
Wherein, it should be noted that the demand in demand library can be divided into subject demands according to the difference of attribute, closed
Key demand, passenger demand and quality constrain demand, the demand in each meta-model may include subject demands, crucial requirement,
At least one of passenger demand and quality constraint demand.Relationship between object and object is and the object pair in meta-model
Membership between father's system point in the system point answered and train composition tree and with the minor structure point in train composition tree
Between inclusion relation, as shown in the table, the relationship between object and demand is object in meta-model and each attribute
Holding relationship between demand or not holding relationship, the relationship between demand and demand be demand in meta-model with it is other
Relationship between the demand of attribute.
| Relation data description | Relation name | Relationship source |
| Train includes vehicle | Inclusion relation | Between object |
| Vehicle includes carrying component | Inclusion relation | Between object |
| Vehicle includes traveling component | Inclusion relation | Between object |
| Vehicle includes power component | Inclusion relation | Between object |
| Vehicle includes other components | Inclusion relation | Between object |
It should be understood that the meta-model finally constructed can be applied in train design, each meta-model includes pair
As, demand and relationship, the object is any one component in train composition, and the demand is that the object institute is right
The technical need for the component answered, the relationship include the upper level component in component and train composition corresponding to the object
Between the inclusion relation between next stage component, the object and the demand of each attribute in membership and train composition
Holding relationship and meta-model in demand and other attributes demand between at least one of relationship.As shown in Figure 2
A meta-model, wherein the object of the meta-model be train composition in running part, demand include subject demands and key
Demand.
It is constructed referring to Fig. 3, Fig. 3 schematically shows a kind of of example according to the present invention to based on train technical demand
The flow chart of method that is operated of meta-model, for example, this method may comprise steps of:
Step 301: the component chosen using user is searched from metamodel data library as the meta-model of object, and as wait grasp
Make meta-model, the metamodel data library includes a Constituent element model；
Step 302: the update of the meta-model to be operated being operated in response to user, to described wait operate in meta-model
Demand is updated.
In order to avoid a large amount of duplicate R&D works can be from meta-model number for some component in train composition
According to the meta-model for choosing the component in library, the demand according to the technical need in task newly developed in the meta-model carries out simple
Update operation, can finally be quickly obtained the meta-model for meeting mission requirements newly developed.
Wherein it is possible to first show a train composition to user (that is, exploitation designer of train) on an interface
It sets (as shown in Figure 1), it is corresponding to choose the object from train composition tree for the object in meta-model that user updates as needed
System point.For example, if user need update be running part meta-model, selected from train composition number shown in FIG. 1
Take " running part " system point.In response, it is pair that server, which is found from metamodel data library with the component that user chooses,
The meta-model of elephant, as meta-model to be operated.
In a preferred embodiment of the present invention, the update operation for treating the demand of operation meta-model adds including demand
Add operation and/or demand delete operation.
For example, showing meta-model to be operated for example shown in Fig. 2 to user finding after operating meta-model.When with
Some requirement item in the meta-model to be operated first is chosen at family, then click delete button when, it can by the requirement item from
It should be deleted wait operate in meta-model.
In addition, finding after operating meta-model, a demand interface can also be shown to user, in the demand interface
Illustrate all demands in all properties, also, demand is divided with attribute.When user first clicks some demand
, when then clicking addition button, it can the requirement item is added to wait operate in meta-model.
In another preferred embodiment of the present invention, can also support to treat operation meta-model in the form of a list or
Tree-shaped form carries out visualization display.
For example, as shown in Fig. 2, being to treat operation meta-model in the form of a list to carry out visualization display.As shown in figure 4,
It is to treat operation meta-model with tree form to carry out visualization display.
Certainly, it is also necessary to which meta-model to be operated not only can be carried out visualization display by explanation, the present invention, can also be with
Train composition and technical need are visualized.For example, train composition is carried out visualization display with tree form, with aobvious
All structures for showing train, including the hierarchical relationship between all parts in structure；By technical need in the form of a list into
Row visualization display.
In addition, in another preferred embodiment of the present invention, it can also be by meta-model to be operated in the form of document
Output.
In the present invention, its desired first mould checked rapidly is found from metamodel data library in order to facilitate user
Type can also search the inquiry with user's input in another preferred embodiment of the present invention from metamodel data library
The meta-model of fields match, wherein inquiry field is at least one of object, demand and the relationship of meta-model.
It can also be in advance each of train composition tree portion in addition, searching meta-model to further facilitate user
Each demand and each relationship in part (i.e. object), demand tree under each attribute set the mark uniquely changed.When
When user searches meta-model, inquiry field is also possible at least one of object identity, demand mark and relation identity.
In addition, in the present invention, it is necessary can also to support that user fills in for object, demand and the relationship in meta-model
Description information.
