本文主要從軟硬件方面描述了一個嵌入式網關的具體設計。硬件方面系統使用嵌入式微控制器作為處理器,不僅要能執行傳統的控制功能,還要能執行與連接因特網相關的功能;軟件設計分為三個模塊:CAN總線設備接口通信模塊、透明網關協議轉換模塊和以太網層應用模塊。

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.
