针对串行通信速度慢、拓扑结构不合理的问题 ,引入LonWorks网络升级串行通信 ,介绍Lon Works网络节点的开发方案 ,并介绍LonWorks的显式报文 ,将原来的通信协议转换成LonWorks网络的通信协议。使用上述技术 ,经实践证明 ,通信效果良好 Aiming at the problem of slow serial communication and unreasonable topological structure, this paper introduces LonWorks network to upgrade serial communication, introduces the development scheme of Lon Works network node, introduces LonWorks explicit message, converts the original communication protocol into LonWorks network letter of agreement. The use of the above technology, proven by practice, the communication effect is good
