摘要: 归纳了开放式数控系统具有的特性,提出了建立开放式结构的数控系统应解决的功能要素确定、系统描述、功能要素的交互方式及彼此间的接口协议4个主要问题·而且针对这些问题,论述了开放式数控系统体系结构各功能要素的确定和控制器体系结构功能构成,并从系统层次化控制结构、系统中的控制流、数据流和构成系统结构模块的组织结构等几方面详细论述了开放式数控系统多角度描述的特点、及系统构成要素之间的关系·最后采用C++语言,给出了控制器中重要的伺服控制功能的接口定义描述,并总结了开发过程中存在的不足之处·

Abstract: Summarizing the characteristics of an open numerical control system, four principal problems are put forward for building the open architecture of numerical control system, i.e., the confirmation of function elements, the system description, the interaction mode of function elements and interface protocol. It follows that it is necessary to discuss how to determine the function elements of the architecture of open numerical control system and the function composition of a controller system architecture. The system characteristics and relation among function elements are explored further in view of the hierarchical control system, control flow in system, data stream and module structure. A definition is given to the interface of servo control function using C++ language from the viewpoint of implementation with the existing insufficiencies in development process summarized.
