摘要
本文在嵌入式实时操作系统VxWorks下配置多网卡通讯进行了研究和实现,并且着重阐述了双网卡同IP同物理地址冗余切换的方法。文中分析了VxWorks操作系统下设备驱动程序在系统中的层次结构和网口设备驱动程序的运行机制,并在此基础上针对Intel82559网络芯片给出了BSP的具体配置和实现代码,这些方法已经成功运用在以PC/104工控机作为硬件平台的项目中。
Under the background of sound countermine system project, considering the actual demanding, multiplex Ethernet cards communication configs based on VxWorks embedded system is presented in this paper. We also describe the double ethernet cards redundancy switch with the same ip and physical address in detail. It analyzes the hierarchy of the device driver in the VxWorks system and the running mechanism of the device driver for the Ethernet card, according to which particular BSP configures and code have been described for Intel 82559 Ethernet chips. The method has been applied in this project successfully,which tanks industrial personal computer PC/104 as the hardware flato
