Research On Virtual Integrated Natural Environment Architecture Of Joint Test Platform

With the development of virtual experiment technology,the construction and service of integrated natural environment has become a public supporting technology and key core technology in the field of virtual experiment at home and abroad.The purpose of this project is to study the framework of virtual integrated natural environment,provide flexible and efficient operation method of virtual integrated natural environment construction for virtual experiment,provide virtual integrated natural environment support for joint experiment,and solve the problems of traditional virtual environment development for specific test tasks,embedded in the test system,non-independent and difficult to reuse,which can be obvious.To improve the efficiency of building virtual integrated natural environment for virtual test system.Aiming at the requirement of virtual natural environment in virtual experiment application,and considering the deficiency of virtual natural environment in virtual experiment system at present,the overall scheme of virtual integrated natural environment framework is designed.The architecture is divided into three parts: the storage of environmental resources,the construction of environmental space and the provision of environmental capabilities.The key technologies involved in these technologies,such as standardization technology of environmental resources,virtual integrated natural environment space synthesis technology and operation service technology of environmental space,are studied.The standardized representation and interaction of environmental data,flexible expansion of environmental resources,free construction of environmental space and the ability to provide environmental services for joint experiments are realized.Based on the research and design of the above-mentioned virtual integrated natural environment architecture,and according to the overall needs analysis of the architecture,this paper develops the integrated natural environment space construction software and environmental space components.The static model and dynamic model are designed by using UML modeling language with object-oriented idea.The design and development are carried out on Qt Creator platform,and the functions of software and components are tested.Based on the joint test platform,the test environment is built for application verification.The virtual integrated natural environment framework can provide virtual integrated natural environment support for the virtual test,which proves that the scheme design is reasonable and meets the needs of the research on the virtual integrated natural environment framework of the joint test platform.
