摘　　要：实验教学是CAN总线原理及应用课程教学中理论联系实际的重要环节.通过实验,可以使学生对CAN总线节点的设计、基本原理和编程方法等知识有较全面的了解和掌握.但是大多数高校的单片机实验箱缺少CAN总线功能,使得CAN总线实验教学无法正常开展.为了解决这一问题,本文设计了一款基于单片机的CAN总线实验教学平台.该平台以51单片机为基础,结合CAN控制器SJA1000和收发器TJA1050设计了一款支持点对点,多点通信和具有CAN232功能的教学平台.实验测试表明,本文设计的CAN总线实验平台,数据通信可靠,可以满足CAN总线实验教学需求,有助于学生对CAN总线技术的理解和掌握.Experimental teaching is an important part in the teaching of CAN-bus principle.By the experiment,students can have a comprehensive understanding of the design,basic principles and programming methods of CAN-bus.However,most of the single-chip microcomputer experiment boxes in Colleges and universities lack the CAN-Bus function,which makes the CAN-bus experiment teaching unable to carry out normally.In order to solve this problem,this paper designs a CAN-bus experimental teaching platform,which is based on 51 single-chip microcomputer,combined with CAN controller SJA1000 and transceiver TJA1050,designs a teaching platform with point-to-point,multi-point communication and CAN232 function.The experimental result shows that the CAN-bus experimental platform has reliable data communication,can meet the basic CAN-bus experimental teaching needs,and can improve students'understanding and mastery of CAN-bus technology.
