摘要:: 通过分析机载航电系统仿真模型存在的问题,给出了XML 数据模型描述的方法和特点,提出了以想定任务需求为仿真建模的驱动数据的方法,基于XML 技术设计了想定任务-飞机-机载装备三层描述关系。分别给出了想定任务和航电系统仿真模型的组成、结构化语言描述、有向树模型及 XML 技术描述的方法,并在此基础上形成规范的系统接口,为系统建模平台的建设提供重要的技术基础。最后,根据有向树和 XML 技术的特点,以节点和元素为基本单元,设计了 XML文件数据访问的操作函数,形成系统建模平台的基础资源,利用设计的 XML 任务描述文件给出了航电系统仿真应用平台的设计架构。分析表明该方法用于航电系统仿真平台的建设将很大程度上提高仿真模型资源的重用性和共享性。

Abstract:: By analyzing the problems existing in the simulation model of airborne avionics system, the methods and characteristics of XML data model description are given,a method of driving data based on the task requirements for simulation is proposed,and based on XML technology, the three-layer description relationship of the task -aircraft-airborne equipment is designed. The composition of the simulation task and the avionics simulation model,the structured language description,the directed tree model and the XML technology description method are given respectively. On this basis,a standardized system interface is formed,which provides an important technical basis for the construction of the system modeling platform. Finally,according to the characteristics of directed tree and XML technology,using nodes and elements as the basic unit,the operation function of XML file data access is designed to form the basic resources of the system modeling platform. The design structure of the avionics system simulation application platform is given by using the designed XML task description file. The analysis shows that the method used in the construction of avionics simulation platform will greatly improve the reusability and sharing of simulation model resources.
