分布式智能协作体系构建集成化开放结构数控系统的研究

数控系统在应用开放结构时 ,往往因各种模块化单元便于集成和组合 ,而倾向于追求密集的软硬件设计和过度的接口及实现全功能特征 ,但也由此造成了数控系统体积庞大 ,接口繁杂 ,功能重叠等负面效应。更重要的是 ,由于没有众多模块在集成化控制过程中的协调关系 ,产生系统逐渐丧失柔性与稳定性且运转臃肿。因此 ,有必要采用适当的分布式设计结构和分散型节点控制策略以保证开放式设计思想的实用性和适度性。本文通过向传统层次化系统结构中引入多维特征 ,分层次的开放结构和节点分组协作等设计思想 ,提出了采用分布式智能协作体系和分层开放机制重构集成化开放结构数控系统的基本技术方案。

Research on Reconfiguration of Integrated Open Architecture CNC System Based on Distributed and Intelligent Cooperation

When applying open control structure in the CNC system, there appears a problem that the structure and controlling of CNC becomes too complicated because of the excessive requirements for function and interface in the more and more easy integration process of modules or nodes, which have resulted in the loss of flexibility and stability and awkward running and operating. In this paper, we present a basic technique scheme for reconfiguring integrated open CNC system based on distributed and intelligent cooperation framework by introducing several key design schemes of multi-dimensional and floating hierarchical architecture, the hierarchical expansion model of open architecture, and the task-oriented node driving tactic.
