摘要组态软件是近年兴起的一个控制软件分支，目前，大多数组态软件产生的组态数据只能由软件本身识别，为实现组态数据的通用性，本文对用XML文档存储组态数据的方法进行了研究。

本文研究的组态软件是通过Microsoft Visual Studio 2008自主开发的、基于MFC的组态软件。软件分为组态环境和运行环境两部分，组态环境可进行监控画面和控制策略的组态，通过对组态界面中各类元素的分析，提出了用XML文档存储组态数据的方案；XML文档可由软件读取生成运行环境，以实现运行环境下可运行控制策略并动态显示监控画面为目标，对控制策略及监控画面的生成过程进行了探索，并得出一种读取方案。66794

最后，本文以实例验证了存储和读取方案的可行性。

Title  The application of XML document in the SCADA

Abstract

The Supervisory Control and Data Acquisition(SCADA) is a control software branch of the rise in recent years. Currently,the configuration data generated by most of the SCADA can only be identified by the software itself.To achieve the universality of configuration data,the method of storing configuration data in an XML document is studied in this paper.

The SCADA researched in this paper is a MFC-based software,developed by Microsoft Visual Studio 2008.The software is pided into two parts of the configuration environment and running environment. Monitor screen and control strategy can be configurated in the configuration environment.Through the analysis of various kinds of elements in the configuration interface, the method of storing configuration data in an XML document is proposed.The XML document can be read by the software to generate running environment.In order to realize the goal that the control strategy can be run and the monitor screen can be displayed dynamically in the running environment,the generation process of the control strategy and the monitor screen is explored.and a method of reading XML document is proposed.

Finally,the feasibility of storing and reading methods are demonstrated with an example.
