摘　　要：以太网通讯设备目前尚不能兼容通讯方式不同的CAN车体总线。为减少开发成本,提出基于以太网CAN模块的总线协议转换网关的设计。经验证明,使用以太网CAN模块作为以太网通讯设备和CAN总线设备的网关实时进行协议转换,满足功能需求,增强设备的可移植性与兼容性,实用性较强。Ethernet communication equipment is not compatible with CAN bus with different communication modes at present. In order to reduce the development cost, this paper puts forward the design of the bus protocol conversion gateway based on Ethernet CAN module. The verification proves that the Ethernet CAN module used as the gateway of Ethernet communication equipment and the CAN bus device for realtime protocol conversion can meet the functional requirements, enhance the portability and compatibility of equipment, and has strong practicability.
