摘　　要：LonWorks控制网络中的动态数据交换技术提供了Windows应用程序和LonWorks网络之间数据有效传输和信息共享的软件支持,Windows应用程序可以担当DDE客户端的角色去观测或者修改网络变量的值,从而实现监督和控制一个或多个LonWorks网络。为了有效实现LonWorks网络种DDE方式的数据交换,本文提出了基于动态数据交换技术的LonWorks网络的2层系统控制结构。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,讨论了DDE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DDE技术的系统结构灵活有效、可扩展性强,可以满足控制功能的要求。Dynamic Data Exchange offered an effective approach of data transferring and sharing between Windows application and LonWorks network, in which Windows application can control several LonWorks networks by observing and modifying the value of NV. In order to make good use of DDE technology, structure of LonWorks control system and the details of DDE 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 DDE technology can be set flexibly and extensibility and can meet the demand of control system.
