一种基于ARM的嵌入式网关系统设计与实现

Design and Realization of Embedded Gateway System Based on ARM

针对以太网与CAN现场总线之间互连的需求,提出一种基于ARM的嵌入式网关系统设计与实现,分别从网关硬件系统组成、协议转换流程以及嵌入式Linux下CAN设备驱动程序的开发方法进行分析与设计。通过软、硬件平台的搭建与测试,实现了以太网与CAN现场总线之间的协议转换,为CAN/Ethernet的互连提供了一种传输速度快、成本低、稳定性高的网关解决方案。

For the demands of interconneetion between Ethernet and CAN fieldbus, ARM - based embedded gateway system is designed and implemented. Analysis and design are carried on respectively from the structure of gateway hardware systems,the processes of protocol transitions and development method of CAN device drivers under the embedded Linux. The protocol conversion between Ethernet and CAN fieldbus is achieved through the build and test of the hardware and software platform. In this paper, a gateway solution for the interconnection of CAN/Ethernet is provided with rapid - trans mission, low -cost and high - stability.
