摘　　要：CAN总线是一种现场总线,特别适用于工业现场设备的网络通讯;PC-104总线是嵌入式PC机的总线标准,嵌入式PC机特别适用于工业现场控制。为了将嵌入式PC机联人CAN网络,设计了一种既具有CAN总线接口又具有PC-104总线接口的适配卡。给出了CAN通讯卡的硬件、软件设计思路与实现方法。该卡已在实践中得到应用,实践证明该设计方法是可行的。CAN bus belongs to field bus. It is fit for communication among industry field nodes. PC - 104 bus is the standard for embedded computer. Embedded computer is especially fit for control at industry field. In order to link embedded computer to CAN bus, an adapter card with CAN bus interface and PC - 104 bus interface has been designed. It provides a method for the designing and realization of the hardware and software of CAN communication card. This adapter card has been used in reality. It proves that this design is feasible.
