摘　　要：本文系统地研究了CAN总线与以太网互连的技术要点,首先分析互连技术在实现过程中遇到的难点——协议转换。然后提出了一种CAN总线与以太网系统互连设计方案,并详细阐述了其系统的软硬件实现方法。为了提高系统的性能,采用高速微控制器SX52来设计嵌入式透明网关,详细介绍了用SX52在TCP/IP协议栈实现的方法,以SX52较强的网络协议处理能力保证了整个系统性能的提升。The gist of CAN bus and internet ethernet network technology are discussed in this paper.First,We analyse difficulty when the protocol was transformed. Second,we put forward a systemic design schema and implementation. In order to improve system performance,We select SX52 with high speed micro-controler to design embedded gateway.at the same time ,we introduce how to use SX52 to realize TCP/IP protocol and improve the performance of network processor so that system can work well.
