基于CAN總線技術(shù)的嵌入式網(wǎng)關(guān)設(shè)計

本文主要從軟硬件方面描述了一個嵌入式網(wǎng)關(guān)的具體設(shè)計。硬件方面系統(tǒng)使用嵌入式微控制器作為處理器,不僅要能執(zhí)行傳統(tǒng)的控制功能,還要能執(zhí)行與連接因特網(wǎng)相關(guān)的功能;軟件設(shè)計分為三個模塊:CAN總線設(shè)備接口通信模塊、透明網(wǎng)關(guān)協(xié)議轉(zhuǎn)換模塊和以太網(wǎng)層應(yīng)用模塊。

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.
