摘　　要：本文研究了高层体系结构(HLA)的基本组成以及当前的应用领域,提出了HLA仿真系统在一些动态、复杂环境中应用存在的问题。在此背景下,本文研究了网格技术的五层沙漏结构,论述其动态演化、资源共享、任务分布协同等特点可以良好地弥补HLA仿真系统中的不足之处,提出基于网格的HLA仿真系统结构。同时,鉴于网格技术具备分派任务的灵活性,结合大规模仿真网络结构的复杂性,给出此结构下适用的两级任务调度算法。将基于网格的HLA仿真系统结构应用于CBTC仿真测试平台的实现中,设计各子系统对应的联邦成员,并且通过网格将所有的计算资源整个进行分发任务工作。This paper studies the basic component and the current application field of HLA simulation system,The problems existing in the application of HLA simulation system in some dynamic and complex environments are put forward.In this context,this paper studies the sandglass model of five layer Grid protocols of grid technology,and then discusses that deficiency of HLA simulation system can be made up correspondingly by its dynamic evolution,resource sharing and collaborative task distribution.therefore,the structure of HLA simulation system based on grid is proposed.Meanwhile,considering that grid technology has the flexibility of assigning tasks,combined with the complexity of large-scale simulation network structure,a two level task scheduling algorithm under this structure is given.The grid based HLA simulation system structure is applied to the realization of CBTC simulation test platform.The federate members of each subsystem are designed,and all the computing resources are distributed through the grid.
