Distribution Of Dynamic Data Processing Technology Research In The Simulation Environment

This paper is the sub-project of the 10th five-year-project: Simulation Infrastructure and Environment Simulation. The paper researches in dynamic data processing technology under the distributing simulation system.The dynamic data in HLA environment includes data collection technology and dynamic environment data. This paper discusses the two technologies.This paper analyzes some traditional data collection tools. It carries out a new self-adaptive general data collection tool. This tool can analyze the FOM table of the simulation system which is stored in a .DIF file. Then it can get the information of the simulation system, and it can configure with this information. So it can be widely used. We also take an experiment to prove that this data collection tool has a high performance on real-time data collection.This paper also takes a deep research in the dynamic environment. It researches how the dynamic terrain data being displayed and interacted in HLA system.This paper discusses a method for visualizing of dynamic terrain with the DEM data. This paper improves an algorithm based on the technology of using extension of resolution with the method of using grads in the terrain's data. Experiment proves that this method can improve the performance of our system.The paper researches in the synthetic environment data representation and interchange specification (SEDRIS). It brings up a structure of hierarchy which can be used to store the terrain data. It also brings up a method which can be used for the data of dynamic terrain to interact with the entity of the simulation using HLA environment.
