Development Of The Visual Modeling Software For Virtual Test System Platform

The widely application of virtual test, increasingly advanced weapons andequipment and more and more complex test environment lead to gradual expansionof the scale of the virtual simulation test. All of that highlights the important role ofthe test mission management in the virtual test system as well as the higherrequirement for the static modeling of the virtual test task.The purpose of this subject is to apply general purpose visual modelingtechnology to virtual test pilot program planning and modeling, to provide userswith a visual modeling environment combined with features of the virtual testplatform for more effective experience in organizing the network of resources, tobuild the test program and generate the corresponding standardization program files,and finally to complete the automatic deployment and collection of the file.This thesis firstly analyzes the scheme of building the virtual test platform,and the principle of the file loading and saving for a single member in it in detail.Secondly, it compares the difference between those general visual modelingsoftware and what widely used nowadays, and find out the key technology and thedifficulties in the generic-purpose visual modeling. Then the paper analyzes thetechnology using in assigning and collecting member files. Finally it realizes thedevelopment and test of the visual modeling software for virtual test systemplatform (hereinafter referred to as the visual modeling software). The softwareeffectively solves the problems faced by virtual test system platform in building apilot task, such as hardware resource constraints, the error-prone and difficultproperty associated and difficult to visually view the relationship between thevarious parts. Thereby, it enhances the degree of automation of the virtual test,improves the reusability of the scheme, and reduces the dependence of thehardware resources in the modeling process.The visual modeling software design adopts the idea of the object-orientedprogramming and completes the software requirements analysis, the static modeldesign and dynamic interaction design using UML. Also, inspired by the idea ofseparating the display from the logical data, the paper designs the structure and theoperation for the scheme individually. It designs a base class for the visual and graphic elements, and makes it meet the specific interfaces of the component in thevirtual test system platform. And finally based on what has done before it achievesa series of visible operation of the graphic elements using the multiple-document-framework in MFC.The testing results in laboratory and the user’s application feedback indicatethat the software is not only reliable, but also user-friendly. What’s more, itsoperation has good consistency and meets the needs of the users.The results of testing in laboratory and the user s application indicate thatthe software is not only reliable, but also user-friendly and. What s more, it’soperation is good consistency and meets the needs of the users.
