针对煤矿安全监测监控系统中CAN 现场总线与以太网互联的需求,采用32 位RISC ARM 处理器,设计了CAN-Ethernet 嵌入式接入网关,运行在Linux 嵌入式实时操作系统上。详 细介绍了网关的硬件与软件设计方案,实现了CAN 总线与以太网的无缝连接。经现场应用验证,该网关较好地完成了两种网络之间的协议转换和数据通信。 关键词: CAN; 以太网; 网关; 消息队列 Abstract: Due to the requirement of the connection of CAN-bus and Ethernet in coal mine security monitoring system, a CAN-Ethernet gateway is designed on the embedded real-time operating system for Linux, using 32 bit RISC ARM processor. The design of hardware and software of the gateway is particularized and the seamless connection of CAN-bus and Ethernet is realized. Fieldwork results show that the device, featuring with redundant capability, can complete the data transmission between CAN-bus and Ethernet. Key words: CAN; Ethernet; Gateway; Message queue
