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。
This paper introduces the structure of the unit-level performance calculation module in the Supervisory Information System (SIS) and its software design process. The application of Component Object Model (COM) technology in the design of SIS module is discussed. Combined with the design process of dynamic link library performance calculation component and database interface, the application of component development technology and OLEDB technology is expounded. In SIS using COM technology for design and development, with good reusability, stable performance, high efficiency and many other advantages, is very conducive to system integration and functionality expansion.
