摘要
为了实现对工业设备的远程监控,针对工业现场总线中比较有代表性的CAN总线与以太网之间的数据交换,提出以S3C2440为主控芯片的嵌入式网关设计以实现网际互联.硬件方面,基于S3C2440的功能和特点外扩了CAN通信模块、以太网通信模块.软件设计上,介绍Linux的移植,CAN驱动设计,并给出了通信协议转换流程图.
In order to realize the remote supervision in the industrial equipment,and according to the CAN-bus that is a typical bus in the field bus switch data with Ethernet,this paper issues a way of design of Embedded Gateway base on s3c2440 to realize the internetworking.This paper briefly described the hardware system、CAN communication module、Ethernet communication module,and also Linux portability 、the design of CAN driver 、the communication protocol flow diagram from the software.
