CAN总线网与以太网嵌入式网桥设计

摘要

基于C8051F040 SOC芯片和CP2200网络接口芯片,设计一种嵌入式网桥连接CAN总线网与以太网,实现网络间数据的智能交换.为远程控制中心直接通过以太网访问CAN现场总线,提供了一种便捷的解决方案.该嵌入式网桥系统可配置,不依赖主机,经工程验证,可满足不同CAN总线与以太网的连接需求.%A way to design an embedded bridge between CAN bus and Ethernet based on C8051F040 SOC chip and CP2200 Ethernet interface chip is presented, which can exchange data intelligently between the two nets. It is a facile solvent for remote control center accessing data of CAN field bus by Ethernet. The embedded bridge is configurable and relies on host anymore. It has ability to link all sorts of CAN buses to Ethernet through actual project validated.
