摘　　要：为了满足某导弹测试设备网络化和一体化的要求,设计了该测试设备LAN接口卡;硬件方面,采用基于ARM的嵌入式系统技术,使用ARM内部Ethernet MAC控制器和外部物理层芯片实现了100 Mbps的LAN接口功能;采用基于寄存器访问的技术,设计了LAN接口卡与功能模块的本地接口;软件方面,以嵌入式Linux操作系统为平台,设计了嵌入式Linux本地接口驱动程序;采用TCP/IP协议设计了网络通信应用程序,实现了上位机通过LAN接口卡对多个功能模块的可靠访问;测试表明,LAN接口卡满足设计要求。In order to meet the requirements of networking and integration in a missile test equipment, LAN interface card in the test equipment is designed. In terms of hardware, it uses the technology of ARM--based embedded system and achieved the features of LAN interface by using the Ethernet MAC controller within ARM and an external physical layer chip; The local interface between LAN interface card and function modules is designed by using the technology of register access. In terms of software, based on the embedded Linux Operating system, embedded Linux driver of local interface is designed; the network communication application is designed by using the TCP/IP protocal. It achieved that a host computer access a number of function modules reliably through the LAN interface card. Tests show that LAN interface card meets the requirements.
