基于CAN总线与以太网的嵌入式通信控制器的设计

Design of an embeddded communication controller based on CAN and ethernet

介绍了一种CAM总线与以太网互连的变电站通信控制器的设计方案,在分析CAM总线与以太网网络模型的基础上,给出了硬件和软件的设计方法,实现了变电站下层现场设备同上层监控网络的通信联系,同时也为变电站的数据管理和远程控制奠定了基础。

This paper introduces an interlinkage designing project between CAN and Ethemet for substation commtmication controller analyzing on the model of CAN bus commtmication protocols and Ethemet commtmication protocols.A designing method of hardware and software is given. The commtmication between field devices and monitoring network is carried out. A along--distance monitor and data management system is estblished for substation
