On this basis a design scheme of the database for SCADA based on the component object model is presented, in which the content and background of IEC 61970 standard is introduced first, then some different component model are assayed , then a design scheme of the database for SCADA based on the component object model is presented, the foreground application of SCADA is connected with the database by components.The new model have some advantages: system have disrelation with develop language ,the peculiarity of COM make the system fit in with different apply program developed with different language;(2) the system can be modified and upgraded easily by means of upgrading the component modules;(3) the system can be enlarged easily by means of adding the new component modules without quiet amendment in old system.

为此，本文介绍了一种基于组件对象模型的SCADA数据库系统设计方案，文中首先介绍了IEC61970标准的内容及产生背景，分析了几种不同的组件模型，在此基础上，提出了一种基于COM组件技术的SCADA数据库设计及访问模式，在此模式下根据SCADA数据库不同的功用划分了不同的组件模块，利用组件连接数据库与SCADA前台应用，基于组件技术的SCADA数据库设计有以下一些特点：(1)与语言无关性，COM的特性决定了此系统上可以应用不同语言开发的应用程序；(2)系统易修改及维护，用户可以通过更新组件模块的方式修改及维护系统；(3)系统易扩展新的功能，用户可以通过开发新的组件方式将新的应用与原系统结合，而不用对原系统做很大的修改。
