Research On LVC Joint Test Architecture And Key Technology

LVC joint test is refer to the simulation test by combing the Live,Virtual and Constructive resources.By using the combination of computer simulation technology and real test,it can save a lot of test cost and enhance the test result.As an important technology of military simulation,it is widely used in the life cycle of weapon system demonstration,program design,key technology verification,system integration test,system training and so on.However,there are some limitations in the current mainstream simulation architecture,such as HLA,which is mainly used in the field of constructive simulation,and TENA is aimed at the live simulation.In order to solve the problem of LVC joint test and realize the interconnection and interoperability of LVC test resources,the LVC oriented architecture is need.Firstly,this paper analyzed the problems that LVC joint test faced which are as follows.The first problem is the mutual recognition of data between different systems.The second problem is the interconnection between systems of different architectures.The third problem is the reuse and combination of test resources.Then,based on the above problems and the corresponding solutions and learning from the extended C4 ISR architecture framework,by studying from the driving requirement of LVC joint test,designed the operation architecture and technical architecture and proposed some key technical problems to the run-time architecture.Furthermore,in view of some key technical problems in the system architecture of LVC joint test system,the research mainly includes: DDS middleware research,research of HLA/RTI based on DDS and time management research of LVC joint test system.DDS middleware research including the research of DDS architecture,communication model,QoS policies and technical characteristics.Research of HLA/RTI based on DDS is based on analyzing the data object model,logical architecture of HLA and DDS,HLA simulation flow and the communication flow of DDS,designed the operation flow of HLA/RTI based on DDS.The time management mechanism of LVC joint test system is mainly based on the difference of different simulation systems in the system architecture,and a unified time management service is designed.At last,on the basis of theoretical research,combined with the HLA software and DDS middleware,some key technologies of LVC joint test are realized and verified.
