家庭电器网络化控制系统中以太网与CAN网络网关的设计与实现

Design and Realization of Gateway between Ethernet and CAN Network in Domestic Electronic Devices Network Control System

提出一种智能家庭信息家电控制的CAN总线与以太网转换的网关设计方案。分析了CAN总线与TCP/IP协议,参考电子控制领域通用的协议,用C语言编制相应的协议转换软件。建立了CAN总线与以太网的通讯模型,实现了CAN总线与以太网之间的相互通讯。辅以工程实例,证明该智能家居通讯方案是完全可行的。

A kind of transforming gateway design protocol between the CAN bus and the Ethernet about intelligent family information electrical appliances is proposed. The CAN bus and the TCP/IP protocol are analyzed by referring to electronic control domain general protocol. Then the transforming protocol software is written in c language. The communication model between the CAN bus and the Ethernet is established and realized. It is proved by examples that this domestic intelligent communication plan is completely feasible.
