Hla-based Data Management System Designed

The content of this paper comes from a project. The project mainly studies the monitoring and control equipment on the tracking ship and how to build an all-digital simulation system.High Level Architecture (HLA) has become IEEE 1516 standard in the distributed simulation world. The distributed simulation platform based on HLA with controllable, repeatability, versatility, has enormous real economic and military significance. It makes efficiency to increase economic and social benefits for the training job and measurement mission.The system in this paper has huge, complex interactive data and high requirement for reliability and real-time property. Therefore, data management is particularly important in the HLA simulation system. The study on data collection and management mechanism based on HLA is of great significance.This paper mainly studies the data collection technology based on HLA simulation, designs and realizes the data management system based on HLA. The paper's main content includes:1. It studies the data distribution collection and management mechanism in the simulation system Based on HLA, and analyzes the data management system requirements and functions, put forward the structure of this system.2. It detailed designs an HLA data management system which puts forward the solutions to collect, designs database and makes research on some important issues including the collection of high-frequency data, big-flow data, heterogeneous data transmission problems and the design of database.3. It achieves the data management system, testing the data management system and analyzing the experimental result.
