基于构件和数据流的雷达组网系统研究

Research of Radar Network System Based on Component and Data flow

为了实现雷达组网系统功能模块和处理流程的动态调整,研究了雷达组网系统所需的开放式体系结构.将系统中的功能模块以软件构件的形式实现,配置构件的连接关系以脚本的形式存储,并以基于事件触发并发数据流模型的总控作为构件连接器,将构件组装形成应用系统,总控按照一定的算法通过接口调用或消息触发的方式实现对构件的调度.在这种结构下,通过添加、删除和替换构件,实现了系统功能模块的动态调整;通过配置构件连接关系,实现了系统处理流程的动态调整.

In order to adjust dynamically the function modules and processing flow of radar network system,an open architecture for radar network system is studied in this paper.Each function module of the system is implemented in the form of software component,and the connections of the components configured are stored in the form of scripts.And the control-in-chief based on event-triggered concurrent dataflow（ECDF） model is taken as the component connector,the components are assembled to form the application system,and the scheduling of components are realized by way of the control-in-chief getting through the interface call or message-triggering according to a certain algorithm.In this architecture,the dynamic adjustment of function modules can be imple-mented by adding,deleting and replacing components,and the dynamic regulation of processing flow can be done by configuring the connections of components.
