COM技术在发电厂SIS系统中应用

Application of COM technology in SIS for power plant

介绍了厂级监控信息系统SIS(SupervisoryInformationSystem)中的机组级性能计算模块的结构及其软件设计过程。探讨了组件对象模型COM(ComponentObjectModel)技术在SIS模块设计中的应用,并结合动态链接库性能计算组件以及数据库接口的设计过程,对组件开发技术和OLEDB技术的应用作了具体阐述。在SIS中采用COM技术进行设计开发,具有复用性好、性能稳定、运行高效等诸多优越性,非常有利于系统集成和功能扩展。

The structure and software design of the unit performance calculation module in SIS(Supervisory Information System)for power plant are introduced.The application COM(Component Object Model)in the design of SIS modules are discussed.Combined with the design of the perfor-mance calculation component in DLL and database interfacing,the applications of component develop-ment technology and OLE DB technology are described in detail.The advantages of applying COM technique in the design and development of SIS are good re-applicability,steady performance,high efficiency and so on,which are very useful in system integration and functional expansibility.
