摘要
本文以LPC2119微控制器为核心设计了客车网络控制中CAN/CAN网桥,实现了不同CAN网段连接、报文过滤和转发功能。文中分析和阐述了该网桥的硬件设计方案和软件设计过程,并通过实验方法测试了网桥的可靠性,从而解决了两个CAN子网的互连问题。
By using of the micro controller of LPC2119, the aim of this study is to design a CAN/CAN Bridge which is used in bus network system and implements the bridge to connect CAN segments, filter messages and also transmit messages from one CAN network to another. This paper analyzes the way of designing the hardware of CAN bridge and detailedly discusses the process of software design. Then the bridge is tested for it＇s reliability. It has solved the problem of connecting two separate CAN network.
