【摘要】：首先，研究了数控系统在国内外的发展现状和发展趋势，五轴联动加工和嵌入式数控系统的特点。其次，对统一建模语言（UML）及并发对象建模与体系结构设计方法（COMET）进行了简单的介绍。然后，基于COMET方法对嵌入式五轴联动数控系统进行分析和设计。基于COMET方法，在需求模型开发阶段，，对研究问题进行了描述，建立了系统的用例模型。在分析模型开发阶段，通过静态模型、对象的构建及动态模型，深入研究了数控系统的内部结构及系统的工作方式。在设计模型开发阶段，根据子系统构造准则将系统划分为I/O子系统、系统服务子系统、用户界面子系统、刀库子系统、运动子系统和控制子系统。根据临时群集、控制群集和互斥群集等原则将系统构建为具有独立执行线程的任务，并在分析模型的基础上建立了任务之间和子系统之间的通信接口。最后，在逐步的分析和设计中得到数控系统的初始软件架构。基于COMET的数控系统软件架构设计，让嵌入式五轴联动数控系统的结构更加清晰，也为后续的详细设计奠定了坚实的基础。
[Abstract]:Firstly, the development status and trend of CNC system at home and abroad, the characteristics of five-axis linkage machining and embedded NC system are studied.Secondly, the Unified Modeling language (UML) and concurrent object Modeling and Architecture Design (COMET) are briefly introduced.Then, based on the COMET method, the embedded five-axis NC system is analyzed and designed.Based on COMET method, the research problem is described in the stage of requirement model development, and the system use case model is established.In the stage of analyzing the model development, through static model, object construction and dynamic model, the internal structure of CNC system and the working mode of the system are deeply studied.In the stage of design model development, the system is divided into I / O subsystem, system service subsystem, user interface subsystem, knife library subsystem, motion subsystem and control subsystem according to the criterion of subsystem construction.According to the principles of temporary cluster, control cluster and mutex cluster, the system is constructed as a task with independent execution thread, and the communication interface between tasks and subsystems is established on the basis of analyzing the model.Finally, the initial software architecture of NC system is obtained in the analysis and design step by step.The software architecture design of CNC system based on COMET makes the structure of embedded five-axis linkage CNC system more clear and lays a solid foundation for further detailed design.
