Fig.8 and 9 show the effect of data transmission, the relative position relationship
between the carrier aircraft and the locked target (in the square and diamond frame) in
the VP is calculated out, then the value is transferred into the multi-function display
developed by GL Studio, in a simulated radar screen relative position relationship
between the carrier aircraft and target is shown.
2. GLS COMPONENT DATA IS TRANSFERRED INTO THE VP
In simulation process, it involves data's transferring from GLS components to Vega
Prime, and in the vpGLStudio VP module that provided function of data's transferring
from VP to GLS components, but transmission does not provide the reverse.
In the process of development, by means of global variables exported in the gener-
ated DLL from the components, data sharing between GLS components and VP can
be implemented. Steps are as follows:
1) Declaration in the header file of GLS component: _declspec (dllexport) int
GlobalData; so that other components can access the global variables GlobalData.
2) Generate the *.dll and. Lib file and it is need to use global variables GlobalData
components to complete the configuration process.
3) The declaration in the VP code: extern_declspec (dllimport) int GlobalData; and
the generated *.dll files are copied to the component folder. So that GlobalData
data in terms of global variables is imported into the VP.
In addition, this method can be used in transferring data from GLS components to
VP, also in transferring data between components.
6 Conclusion
The Implementation of "simulation experiment platform of airborne fire control
equipments" system involves a large number of functional modules, which is a simu-
lation software developed home with the combination of semi-physical, also is the
simulation software of a carrier aircraft fire equipments with more complete feature,
and offers a standard application program interface, efficient integrated environment
and a rich graphical display feature. It can improve the sense of reality, real-time and
degree of visual data of visual simulation systems; what is more, it will become a new
simulation method for the rich semi-physical simulation experiment.
