摘　　要：针对现有的CANopen网络的实现方法,提出了一种基于SOPC技术的CANopen节点的设计方案。应用IP核复用技术将CAN控制器IP核、主控制器C8051IP核、程序RAM与数据ROM IP核集成在一块FPGA实现底层的CAN控制器SOPC系统。以嵌入式软件方式实现应用层协议CANopen并加载至主控制器中,从而构建了一个CANopen节点。实验测试表明,该CANopen节点通讯符合协议标准,并且性能良好。According to the implementation of existing CANopen network, a design algorithm of CANopen node based on SOP（2 technology is presented. Firstly tile underlying CAN controller system of CANopen composed with CAN controller IP core, the main controller 8051IP core, program RAM and data ROM IP core were integrated in a FPGA chip by the IP core multiplexing. Secondly the applied layer protocol CANopen are achieved by the design of embedded software and loaded into the main controller to construct a CANopen node. And last the experimental verification shows that the CANopen node communication satisfy proto col standards and has good performance.
