摘　　要：在分析Profibus和CAN两种现场总线的特点和开放式数控系统特征的基础上,提出基于双现场总线的开放式数控系统体系结构。研究和划分了数控系统组件,介绍开放式数控系统运动控制的实现。由于采用了双总线结构,能大大减少信息流的冲突,可提高系统的可靠性和传输效率,为高速、高精度数控加工提供了有效的途径。The characteristics of fieldbus and open CNC system are analyzed and researched. The architecture of the open CNC system based on double fieldbus is presented. The CNC system components are studied and divided,and the implementation method of motion control is introduced. The conflict of information flow is reduced greatly for adopting double fieldbus. The reliability and transmission efficiency of CNC system are improved. A feasible approach is supplied for NC machining of high speed and high precision.
