Design And Implementation Of Distributed Battlefield Simulation System Based On DDS

With the improvement of computer simulation technology,the battlefield simulation system is used to set up combat mission scenarios,and to deduce and simulate the battlefield environment and combat process where the equipment or platform is located.The battlefield simulation system can not only support the comprehensive evaluation of the combat effectiveness of the equipment in different combat environments,but also support the test and verification of the technical improvement of the equipment by combining with the digital model of the equipment.Firstly,this thesis briefly describes the background and significance of the development of distributed battlefield simulation system,and compares the advantages and disadvantages of HLA and DDS respectively.Based on the project development cost and schedule requirements,the development scheme of distributed battlefield simulation system based on DDS is adopted.Because the defects of the lack of simulation member management mechanism and time synchronization mechanism in DDS,a simulation member management mechanism based on DDS environment and a two-layer time management mechanism for real-time response requirements were developed to ensure the orderly operation of the entire simulation system.On this basis,the overall architecture design of the distributed battlefield simulation system is completed,the definition of the system network message is defined,and the system database design is completed according to the operation needs of each functional software,so as to form a unified database application module that can be applied to all functional software of the system.Finally,team members completed the detailed design of each functional software,and completed the design and development of the sensor simulation software based on the VS2008.The distributed battlefield simulation system is tested and evaluated based on a comprehensive identification technology pre-research project.The development of distributed battlefield simulation system has effectively improved the requirements of simulation environment for several technology pre-research projects in the factory,which is of great significance to accelerate the technological development of the factory equipment.
