摘　　要：图形组态仿真软件组态数据的存储通常采用流式文件或数据库,这些存储方式使程序对数据结构的依赖性强、可重用性差、且不利于软件的升级和维护。本文采用XML技术规范对图形组态信息进行描述,以XML文件作为功能组态模块与组态软件和其他系统的中介。通过分析提出了采用具有面向对象的分层设计方法来建立控制系统的图形组态数据结构,并阐述了生成和访问基于控制系统图形组态数据的XML文件的方法。应用表明,XML技术可以有效地提高图形拓扑结构的识别效率以及仿真软件的运行效率。The diagram configuration data of the traditional diagram configuration simulation software are mostly stored in the form of stream document or database,and the program strongly relies on data structure,so it is difficult to upgrade,maintain and reuse the software.In this paper the information of diagram configuration is described by XML technology and thus XML document becomes the agency of function configuration block and diagram configuration software to overcome the disadvantages of stream document.First,two definition means of diagram configuration topology structure based on control system are introduced.Second,a diagram data structure adapted to control system simulation software.is found out by analysis and comparison.Finally,an example is given to explain the application of XML technology in the diagram configuration data storage.
