摘　　要：设计了一种基于虚拟令牌传输协议的LonWorks监控系统。系统主要由监控节点、iLON100、LNS、LonMaker和LNS DDE Server构成,利用主机AT89S51和从机TMPN3150设计了LonWorks监控节点。分析了并行接口虚拟令牌传输协议,给出了并行接口在主机AT89S51和从机TMPN3150之间的数据通信和数据向总线解析过程。实践表明,该系统实时性好,精确性高。A LonWorks monitoring system was designed based on virtual token transmission protocol. The system contained monitoring node,iLON100,LNS,LonMaker and LNS DDE Server. The LonWorks monitoring node was designed based on AT89S51 and TMPN3150. The virtual token transmission protocol of parallel interface was analyzed. The course of virtual token transmission and data communication between AT89S51 and TMPN3150 was given. The practice showed that the system was good real-time and of high precision.
