摘　　要：提出了一种基于Profibus-DP总线与PXI总线的开放式数控系统的设计方案。对总线的时间特性进行了分析,其满足数控系统加工控制高速度、高精度的要求。控制器采用IPC架构,通过对功能单元的不同配置实现数控系统的快速重构。同时,基于网络技术,采用三层集成监控的模式,将状态监测、故障诊断、加工优化等技术融合到数控系统中。最后,利用已开发出的原型机验证了方案的可行性。Facing the trends of the computerized numerical control（CNC） systems towards multifunction and high integration possible leading to real-timeness and robustness problems caused by condensed information exchange,an open CNC system configuration was proposed based on Profibus-DP and PXI buses.The time behavior of the buses was analyzed,it was found they meet the demand for high speed and high precision.The controller uses the IPC framework,accomplishes the software function using the component technology,realize the rapid reconstruction of CNC by different allocation of functional components.The functions of state monitoring,failure diagnosis and processing optimization are fused into the CNC system using a 3-layer network.The prototyped machine based on IPC framework proved the feasibility of the CNC scheme.
