摘　　要：设计了应用于分布式控制结构的CAN总线通信系统.采用总线型拓扑结构以及利用分布式控制思想,在CAN控制器的链路层网络协议基础上,设计了应用层协议和传输层协议,实现批量数据透明块传输及自动错误重传,提高数据通信的可靠性.系统已应用于微量元素检测仪器中,运行结果表明:该通信系统工作稳定,实时性好,执行效率高.This paper presents a CAN bus communication system used in distributed control structure,using the bus topology and distributed control thought. Based on the data link layer network protocol of the CAN controller,the application layer protocol and transport layer protocol are designed,achieving bulk data transparent block transfer and automatic error retransmission,and improving the reliability of data communication. Systems have been used in trace detection instrument development. The result shows the communication system is stable,real-time,and highly efficient.
