摘　　要：介绍了CAN总线网络系统中PC机端适配卡和检测端的最小CAN节点的硬件组成及软件设计方法。系统的网络拓扑结构为总线型。在上位机适配卡的设计中,针对ISA总线和卡上单片机同时对双口RAM读写数据时的仲裁问题,提出了一种硬件判优方法。The design and implement of both hardware and software of the CAN adaptor and CAN note are described in terms of PC terminal in CAN fieldbus. Systematical topology structure is of bustype. The hardware optimization method is suggested to arbitration problem on RAM data against ISA bus in regard of adapter design.
