摘要
简要介绍了CAN总线接口芯片SJA1000的结构和性能。描述了在嵌入式船舶自动化异构网络中网关的设计方案。详细阐述了嵌入式系统中CAN总线/Ethernet互联装置之间的协议及其转换。嵌入式网关为两个网段之间提供了透明的数据传输服务,能实现一个网段的设备可以通过网关读取另一个网段中的数据并完成控制计算的功能。
The paper briefly introduces the structure and property of the CAN bus chip SJA1000. A design scheme of the gateway for embedded ship automation heterogeneous network is described. The protocols of CAN bus/Ethernet interconnection devices in embedded system and their transformation are presented in detail. The embedded gateway provides transparent services of data transmission between two different network segments,it can realize the function that a device in one network segment read the data in another network segment through the gateway and implement controlling computation.
