摘要
本文介绍一个CAN与以太网之间网关的设计;电路采用了以ARM7为核心的LPC2292单片机,其丰富的资源和强大的处理功能简化了电路,提高了转换速度。软件设计分为几个任务模块,为两类网络的报文帧格式的转换制定了一套合理的规则。RTOSI的引入,提高了软件开发和维护的效率。该网关可用于分布式控制系统中CAN和以太网的互连。
This paper presents a design of gateway between CAN and Ethernet. its circuit has microcontroller LPC2292 with ARM7 core which has more resource and powerfull capability, these bring simpler circuite and high speed; Its software comprises several task modules and the protocol for message exchange between the two dissmilar networks. Its program and maintenance was more efficient with RTOS. The gateway can make CAN and Ethernet to interconnect in a Distributed Controll System.
