摘　　要：随着千兆网络的逐步全面积覆盖,现用的百兆网关工业设备将被淘汰。为改进现用的网关设备,文中提出了一种千兆网与现场总线的互联设计。在硬件设计中,分为CAN模块电路和千兆网模块电路两部分。AX88180和M88E1111为构成千兆网关模块的主体器件;在软件设计中,以Vx Works操作系统作为软件平台。利用Socket编程完成了网络协议和CAN总线协议的相互转化。通过测试证明,设计千兆网关的可实用性。A design of the intereonnection between Gigabit ethernet and CAN bus is proposed to improve the performance of current industrial gateway equipment. The hardware consists of the CAN circuit module and the Gigabit gateway circuit module with ax88180 and m88e1111 as the major components. The software is based on the Vx-Works RTOS platform. The socket programming is employed to realize the protocol conversion between Ethernet and CAN Bus. Tests yetify that the design of Gigabit gateway is feasible.
