复杂分布仿真系统支撑环境的研究与开发

为促进不同领域、不同类型仿真应用的互操作与可重用,开发了基于高层体系结构接口规范1.3、具有良好实时性和可扩展性的运行时间框架软件———AST-运行时间框架,实现高层体系结构规范中的联邦管理、声明管理、对象管理、时间管理和数据分布管理。深入讨论了AST-运行时间框架的总体技术、时间管理、资源存储方案以及通讯机制,并进行了软件测试分析。介绍了AST-运行时间框架用于飞行模拟训练环境的应用实例。

Research and development on complex distributed simulation system support environment

In order to facilitate the interoperability and reusability of various simulation applications of different domains, a Run Time Infrastructure (RTI) software, namely AST(Advanced Simulation Technology)-RTI, was developed. This software was based on High Level Architecture (HLA) Interface Specification version 1.3, which is the newest standard of distributed interactive simulation. AST-RTI realized federation management, declaration management, object management, time management and data distribution management and showed excellent performance. The principle of RTI design was studied, and the time management, resource storage as well as communication mechanism in AST-RTI were discussed in detail. The software testing was finished. Finally, an instance of AST-RTI-based flight simulation training environment was demonstrated.
