摘　　要：提出一种工业现场总线与以太网互联方法,介绍以太网与CAN现场总线之间协议转换网关的设计与实现,采用AT89C55作为主处理器,通过两个接口芯片实现CAN总线与以太网的互连,分别给出其硬件结构和软件设计思想。经实际验证,该设计比同类产品,具有更高的性价比,为企业信息网络与控制网络集成提供一种可行的方法。An industrial fieldbus and Ethernet Connection approach is put forward. The design and implementation of a gateway for transfer protocol between CAN bus and Ethernet are introduced. The AT89C55 is used as the main processor. And implementation is gained by the connection of Ethernet and CAN. The structure design of its hardware and software is given. Verified through practice,this design has higher cost performance ratio than similar products. A feasible solution for the company is provided to integrate information network and control network.
