Data collection system for HLA-based simulation

In an HLA-based distributed simulation system, the data collection is a key technique, which is prerequisite for analyzing simulation data and acquiring simulation result. In HLA, a federate is free to define the format of the message exchanged among federates, which makes the implementation of the data collection system more complex than in other simulation environments. Some aspects of data collection system in HLA-based simulation is introduced, including architecture, main function modules and corresponding implementing method. Some key technologies in detail is discussed and new opinions on logging format and storage format of simulation data are presented. The data collection system, as an important part of the simulation system, has been successfully applied in the system integration and debugging process of the synthetic simulation environment project. The result proves that the data collection system can evidently increase efficiency, objectivity and veracity and shorten the cycle time of system integration and debugging.
