摘　　要：利用i.Lon 100 Internet Server所提供的Web Service功能可以满足远程用户和LonWorks控制网络之间数据有效传输和信息共享,通过i.Lon 100的SOAP/XML接口,远端Windows应用程序可以观测或者修改LonWorks网络中的网络变量值,从而实现监督和控制一个或多个LonWorks网络;以一个典型的LonWorks监控系统中一个网络节点的输入/输出应用为例,提出了基于Web Service技术的LonWorks网络的两层系统控制结构,讨论了Web Service技术在LonWorks系统中的具体实施方法;从实际应用效果来看,基于Web Service技术的系统结构可以满足控制功能的要求。Web Service of i. Lon 100 Internet Server offered the effective approach of data transferring and sharing between user＇s appheation and LonWorks network, in which Windows application can control several LonWorks networks by observing and modifying the value of NV by SOAP/XML interface. Structure of LonWorks control system and the details of Web Service realization on the LonWorks, which depicted by a typical input ＆ output application of a LonWorks networks node in a control system, have been discussed in this paper. As a result, the structure of LonWorks networks based on Web Service technology can meet the demand of control system.
