基于认知的战场地理环境仿真对象数据模型

Data Model of Battlefield Geographic Environment Simulation Object Based on Cognition

针对目前战场环境认知主动服务的迫切要求,使得传统战场环境数据模型难以满足其需求,需要构建一种面向认知的战场环境仿真数据模型。分析了面向任务的战场地理空间认知过程的特点,构建认知过程概念模型;分析战场环境对象认知结构特征,通过面向对象方法对战场地理环境仿真对象进行层次化结构划分,并使用SEDRIS统一描述对象数据模型;基于工作流的认知驱动机制,对认知过程和仿真对象数据模型进行集成,建立动态数据模型。基于该模型设计战场环境信息系统数据服务框架并应用,验证其合理性与可扩展性。

Aiming at the urgent demands on present battlefield environment cognition active service, its requirements are hard to be satisfied by the traditional battlefield environment data model, thus a kind of battlefield environment simulation data model needs to be constructed. The characteristics of task-orientated battlefield geographic space cognition progress are analyzed, and the cognitive process concept model is constructed. The characteristics of battlefield environment object recognition structure are analyzed;the hierarchical structure division is implemented on battlefield geographic environment simulation object with object-orientated method;and object data models are described uniformly with SEDRIS. Based on cognitive-driven mechanism of workflow, the cognition process and simulation object data are integrated, and the dynamic data model is established. The battlefield environment information system data service framework is designed based on this model, and its rationality and extensibility are verified through application.
