摘要
设计了一个嵌入式异构网络互联网关,实现计算机网络与现场总线异种网络的互联。讨论了网关的硬件构架以及以太网接口、CAN总线接口的具体设计,介绍分析了嵌入式Linux操作系统下的设备驱动程序、嵌入式TCP/IP的实现过程。在实验室条件下模拟了网关的应用环境,对网关的接口和性能的可靠性和正确性进行了测试,实验结果表明,网关较好地实现了数据通信和协议转换功能。
Based on embedded operation system Linux, the gateway is designed to interconnect the embedded heterogeneous networks, interconnection between computer networks and heterogeneous Field-bus is realized. Interface circuit of Ethemet, module design of CAN bus and hardware frame of this gateway are discussed in detail. Then the introduction of Ethernet device driver process and the im- plementation of embedded TCP/IP are analyzed. The application environment is simulated in lab, the test to the reliability and exactitude of interface and performance is done. The experimental results show that IU can performance correctly and implement the protocol conversation faction.
