摘　　要：本文研究了基于上位机通信板卡和100个CAN2.0B节点的多节点CAN总线网络的设计方案以及通信设计方案,并且结合实际工作环境给出了终端电阻实际值;最后提出了基于上位机的多节点CAN网络通信测试方案。实验结果表明,该多节点CAN网络系统方案可靠稳定,实用性强。A multi-node CANbus 2.0 B network which contains one upper computer communication circuit board and 100 nodes is discussed in this paper. The communication circuit scheme of this multi-node CANbus is proposed, and the actual value of terminal resistance is discussed. Finally, the testing solution based on the upper computer circuit board is proposed. The experimental results show that the multi-node CAN network system is reliable and practical.
