利用通用数据交换模型实现多体系结构系统互操作的方法

为解决分布式体系结构互联时存在的互操作问题,提出利用通用数据交互模型描述异构系统间的交互信息,给出了通用数据交换模型元模型的构建方法.将异构系统间交换的信息分为状态(对象类)、事件(交互,由状态改变引起)、控制信息3类,预定义常用的通用消息模型和体系结构相关的消息模型,并设计了通用数据交换模型的创建方法,提升了扩展能力.基于该方法可实现集中式和分布式通用网关,利用回调机制、对象反射和主动发送等"推""拉"通信模式可实现信息的异步传递.通过HLA、TENA与某指控平台的互联验证了方法的有效性.

Multi-architecture System Interoperability Approach Using Common Data Exchange Model

To resolve interoperability problems between distributed architectures when inter-connected, common data exchange model is put forward to describe the information exchanged between heterogeneous systems, and the method constructing meta-model of common data exchange model is designed. The information exchanged between heterogeneous systems is divided into three types including states ( object class) , events ( interactive class ) and control. Information models of architecture-independent and architecture-neutral are predefined, and the method creating new information exchanged is designed, which boosts the expansibility of gateway. Centralized and distributed architectures of gateway is designed based on the method, and “push” and “pull” communication modes is used to realize the asynchronous reception including callback mechanism, object reflection and positive sending. The inter-connection between HLA, TENA, and certain command and control system validate the effectiveness.
