Embodiment
Below in conjunction with accompanying drawing, method SA view file being converted to HLA Simulation Application file provided by the invention is described in detail:
As shown in Figure 1, the invention provides a kind of method SA view file being converted to HLA Simulation Application file, comprise the following steps:
S1, reads source SA view file, obtains the configuration parameter information of described source SA view file;
S2, according to described configuration parameter information, is converted to the HLA Simulation Application file meeting HLA standard by described source SA view file.
In the present invention, HLA Simulation Application file includes but not limited to FOM (FederationObjectModel, federated-object model) file and SOM (SimulationObjectModel, simulation object model) file, below for FOM file and SOM file, introduce method SA view file being converted to FOM file respectively, and, SA view file is converted to the method for SOM file.
One, SA view file is converted to the method for FOM file
When configuration parameter information is the data structure descriptor of described source SA view file, data element descriptor and data type conversion mapping relations, according to these configuration parameter information, described source SA view file can be converted to the FOM file meeting HLA standard; Wherein, data structure descriptor is used for the storage organization that data of description flows to, and data element descriptor is used for the data type of each element in data of description structure.As shown in Figure 2, method SA view file being converted to FOM file specifically comprises the following steps:
S21, the mapping relations of definition SA data type and HLA data type;
In this step, SA data type comprises one or more in SA String data type, SA integer data type, SA single-precision floating-point data type, SA double-precision floating point data type, SA Boolean type data type and SA data of enumeration type type.SA data type with the mapping relations of HLA data type can be: SA String data type corresponding become HLA standard characters data type or Unicode String data type, SA integer data type, SA single-precision floating-point data type, SA double-precision floating point data type, SA Boolean type data type and SA data of enumeration type type corresponding become the corresponding data type of HLA.SA complex data type needs the basic data type for inside, does the conversion of basic data type corresponding to corresponding HLA.
The SA data type conversion of described source SA view file, according to the mapping relations of described SA data type and HLA data type, is corresponding HLA data type by S22;
In this step, concrete conversion regime can be: the maximum length presetting HLA data type requires and byte high-low-position storage sequence requirement; When after the HLA data type by the SA data type conversion of described source SA view file being correspondence, judge whether the HLA data type of described correspondence meets described maximum length requirement, if do not met, then give up described HLA data type; If met, then according to HLA data type described in the described byte high-low-position storage sequential storage preset.
S23, arranges the first corresponding relation of object class in SA data structure and HLA, and, the second corresponding relation of interactive class in SA data structure and HLA is set;
Owing to not specifying the data structure of corresponding HLA object class in SA view file, and, do not specify the data structure of corresponding HLA interactive class, therefore need the corresponding relation of specifying all data structures and object class and interactive class.
S24, according to described first corresponding relation and the second corresponding relation, obtains storing the corresponding relation file of the 3rd corresponding relation of interactive class in object class in described HLA data type and described HLA or described HLA;
S25, adds FOM configuration file in described corresponding relation file, obtains the FOM file meeting HLA standard.
Wherein, FOM configuration file comprises data dictionary, synchronous point, transmission conditions, RTI arrange in switch, user tag, annotation, MOM management information one or more.
Concrete, according to the requirement of HLA to FOM file, interpolation data dictionary, synchronous point, transmission conditions, RTI arrange the contents such as switch, user tag, annotation, MOM management, final generation FOM file.
By above-mentioned steps, achieve effect SA view file being converted to FOM file.
Two, SA view file is converted to the method for SOM file
When described configuration parameter information is each node data stream information in the SA view file of described source, described source SA view file is converted to the SOM file meeting HLA standard, wherein, data stream is used for data of description and flows to, as shown in Figure 3, method SA view file being converted to SOM file specifically comprises the following steps:
S31, according to each node in SA, generates corresponding HLA federal member;
S32, according to each node data stream information in SA view file, extracts the transmission between the object class of HLA federal member described in each and interactive class and reception relation, obtains SOM original document;
S33, adds SOM configuration file in described SOM original document, obtains the SOM file meeting HLA standard.
Wherein, SOM configuration file comprises data dictionary, synchronous point, transmission conditions, RTI arrange in switch, user tag, annotation, MOM management information one or more.According to HLA to the requirement of SOM file, interpolation data dictionary, synchronous point, transmission conditions, RTI arrange the contents such as switch, user tag, annotation, MOM management, finally generate SOM file.
In sum, in the present invention, data streaming file, Data Definitions File and data element file can be generated according to SA modeling result, due to the announcement/order relationship consistency in the content that describes in data streaming file and HLA, Data Definitions File and data element file are combined, just be the object class or interactive class that define in HLA, therefore these three files merged the FOM file just generating HLA emulation needs and SOM file.
Therefore, method SA view file being converted to HLA Simulation Application file provided by the invention, SA and HLA is combined, build the bridge from system modeling to HLA Simulation Application, SA view file is converted into the object class that HLA emulation can be cognitive, interactive class, attribute and parameter information, take full advantage of the modeling result of SA, HLA is made to emulate the result of design inheriting SA accurately, HLA is avoided to emulate the design philosophy departing from SA, and experimenter does not need to edit FOM file and the SOM file that HLA emulates needs, thus alleviate the workload of experimenter.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should look protection scope of the present invention.
