CAN总线在机床数控系统中的设计应用

Design of CAN bus and application for the CNC system

本文介绍了实验型电弧加工机床在强电磁干扰下应用CAN总线实现机床控制单元多主机通信,以保证实时性和可靠性。设计了数控系统与伺服控制器的CAN总线协议和数据结构。该系统具有抗干扰能力强,结构灵活的特点。

Thls article introduced the experiment electric arc processing CNC system applies the CAN bus realization control unit multi-main correspondence under the strong electromagnetic interference. Has designed the CNC system and the servo controller CAN Bus agreement and the construction of data. The design has many characters such as antijamming ability flexible structure,good extension and so on.
