基于CAN总线技术的嵌入式网关设计

本文主要从软硬件方面描述了一个嵌入式网关的具体设计。硬件方面系统使用嵌入式微控制器作为处理器,不仅要能执行传统的控制功能,还要能执行与连接因特网相关的功能;软件设计分为三个模块:CAN总线设备接口通信模块、透明网关协议转换模块和以太网层应用模块。

The Embedding Gateway Design based on CAN Bus Technology ZHONG Jiamin 1, WANG Guocai 2 (1. Dep. of Computer Engineering, Anyang Institute of Technology, Henan Anyang, 455000 2. Shanghai Jiaotong University, Shanghai, 200240) Abstract: A new embedded gateway design is described in detail based on the software design and hardware design. For the hardware design, it adopts embedding micro-processor as MCU, which not only executes the traditional function, but also connect to the internet; For the software design, it’s composed of three modules: CAN bus equipment interface communication module, purify gateway protocol transform module and Ethernet application module.
