本文首先论述了体系结构对大型自动化系统开发的重要意义，接着从生命周期的观点、递阶控制的观点、自控系统组成三要素的观点对体系结构进行了竖向、纵向、横向的分析。并讨论了各类参考模型对支持平台的要求，最后提出了大型过程工业自动化全过程体系结构，该体系结构对“八·五”攻关课题“大型过程工业综合自动化总体技术”具有指导作用。 This paper first discusses the importance of architecture for the development of large-scale automation systems. Then, it analyzes the architecture vertically, vertically and horizontally from the point of view of life cycle, hierarchical control, and the composition of automatic control system. And discusses the requirements of various reference models for the support platform. Finally, the whole process architecture of large-scale process industrial automation is put forward. The architecture has a guiding role in the “8.5” key project, “the overall technology of large-scale process industry integrated automation.”
