本文介绍了LonWorks和CAN现场总线应用的现状,在阐述其通讯必要性的基础上,提出了一种基于单片机技术的LonWorks和CanBus数据通讯的方案,完成了LON总线与CAN总线数据通讯协议控制网关的设计。该协议网关很好的解决了在同一控制系统中LON总线和CAN总线的交叉应用问题。
This paper introduces the status quo of LonWorks and CAN fieldbus applications. Based on the necessity of communication, a scheme of data communication between LonWorks and CanBus based on single chip microcomputer technology is proposed. The protocol of LON bus and CAN bus data communication protocol control gateway the design of. The protocol gateway solves the problem of cross application of LON bus and CAN bus in the same control system.
