本文以华中理工大学对锻压设备数控系统的研究为例，阐述了锻压设备数控系统体系结构从集中式控制模式→STD总线结构的网络分布式控制模式→以ISA总线工控机为平台的分布式控制模式→基于个人计算机的虚拟分布式控制模式的发展历程。
In this paper, huazhong university of science and technology forging equipment numerical control system as an example, elaborated forging equipment numerical control system architecture from the centralized control mode → STD bus structure of the network distributed control mode → ISA bus IPC as a platform for distributed control Mode → personal computer-based virtual distributed control mode of development.
