Construction of Numerical Control System for Aspect-oriented Orthogonal Structure

针对数控系统的实时性、嵌入式特征以及面向特定制造工艺的特殊需求,提出一种面向方面正交结构的数控系统。以构件、方面构件和连接件为核心,组成硬件控制中心和时间控制中心,基本构件和连接件硬件完成控制功能,时间控制构件与连接件实现时间控制功能,通过方面构件横切实现不同线索之间的构件在时间上的关联。分析结果表明,该方法利于系统性能分析和组装应用,便于数控用户的重构。

According to the numerical control system of real time property, embedded characteristics and for the special needs of specific manufacturing technology, this paper puts forward the a construction method of numerical control system for aspect-oriented orthogonal structure. The system structure designed includes basic component, aspects component and connector as the core elements constitute hardware control center and time control center. Hardware control function from the basic components and connectors, time control function is composed by the time aspect component and connectors. The components correlation in time between different threads is realized by aspect-oriented component crosscutting. Analysis results show that this method is beneficial to the system performance analysis and assembly application, and easy to the reconstruction of the numerical control users.
