Key Technology Research Of Team Training Simulation Support Platform Based On HLA

HLA is an open and object-oriented architecture. At present, HLA is mainly used inmilitary confrontation simulation and equipment simulation, and effective team simulationtraining system simulation platform based on HLA is still missing. Moreover, thetraditional HLA Distributed Interactive Simulation Technology for specific needs of teamsimulation training system, there is also some problems of time synchronization and datainteraction.For time synchronization problem, on the basis of time synchronization method basedon the synchronization point, this paper proposed a time-based method of timesynchronization source. In advancing the time, the time synchronization method does notrequire the simulation entities joined the Federation. Simulation entities can be added atany time or to secede, and does not affect the time and therefore more flexible. Andsynchronization time consume less, less affected by network latency and timesynchronization more accurate.For data interaction problem, the different types of simulation data are defined by aunified interactive class in this paper, and a unified data format is provided for the upper.This can improve the flexibility and maintainability of team simulation training platform.And application of the DDM to complete the data distribution operations, reduce networktraffic flow.On this basis, the paper design team simulation training support platform, and theplatform is applied to the development of the National Economic Mobilization SimulationTraining System. Pass the test to prove the practicality of the platform.
