摘　　要：对 COM技术和 OPC规范进行简要介绍后 ,指出基于 COM技术 /OPC规范的开放式数控系统的优势所在。提出了开放式结构数控系统的层次模型和工作流程 ,并以此为基础 ,研究了一个实例系统的软硬件结构。该实例的硬件采用自行开发的 DSP运动控制卡 ,软件采用 COM技术 ,硬件驱动程序符合After brief introduction to COM technology and OPC specification, the advantages of open architecture CNC system that is based on COM and OPC are described in this paper. A hierarchical model and workflow of the open architecture CNC system are presented. According to this model and workflow, the software and hardware architectures of an example system are studied. The hardware of the example adopts DSP motion control card self-developed, the software architecture uses COM technology, and the hardware driver program conforms to OPC specification.
