摘　　要：提出了一种基于CAN总线结构的嵌入式机床数控系统与伺服驱动器之间的通信接口的设计方法,解决了数控系统与伺服驱动器间指令信息误差对数控系统性能的影响。设计了数控系统与伺服驱动器间基于CAN总线的数据结构。设计的基于CAN总线的数控系统接口具有集成度高、结构灵活、可扩展性好、性价比高等特点。The paper presented one kind of design method for the interface based on the CAN bus structure, which avoided the system performance to be influenced by the command information error between the CNC and the servo system. The data struction was designed based on the bus structure between the CNC and the servo system. The system given here has many characteristics, such as high integration rate. flexible structure, good extension, high ratio of price to performance, and so on.
