集成功能块和UML-RT的功能块适配器研究

Study on function block adapter for integrating function block and UML-RT.

分布式工业过程测量和控制系统常以功能块来构建,而利用UML-RT建模又便于实时控制系统的扩展,这要求集成UML-RT组件和功能块,实现UML-RT协议到功能块协议的映射。研究了用于连接UML-RT封装体和IEC61499功能块的模型元件:功能块适配器,它提供了同UML-RT封装体和功能块相交互的接口。描述了功能块适配器的概念、结构及接口,说明了功能块适配器的执行模型。

The industrial-process measurement and control system is usually constructed by function blocks,but modeling with the UML-RT can be conducive to the expanding of the real-time control system,which requires the integration of the UML-RT components and function blocks in order to achieve the mapping of protocols between them.In this paper we introduce a new modeling element：Function Block Adapter （FBA）,which is responsible for the connection of UML-RT capsule and IEC 61499 function block.FBA provides interfaces to ports,to function blocks,and a description of the mapping between these interfaces.We also describe the concept,structure,interface and the execution model of FBA.
