构件技术与开放的SCADA/EMS/DMS系统

SCADA／EMS系统的开发一直紧跟软件工业的发展趋势，构件技术的发展使SCADA／EMS系统开放设计发生根本性改变。探讨了开放的SCADA／EMS／DMS系统的体系结构，即在应用程序（或构件）接口语义级上采用公共信息模型，面向对象技术和构件技术的有机结合可实现不同应用间的相互操作和无缝连接，而采用XML技术实现的信息交换模型将简化和加速数据对象标准化过程，此外，初步讨论了现阶段系统开发可能碰到的问题。

Component Technology and Open Architecture of SCADA/EMS/DMS

The development of the SCADA/EMS always follows the trend of software industry, and the component technology will significantly influence its development and design. As the software architecture for open SCADA/EMS/DMS, a scheme is presented, which adopts Common Information Model (CIM) to describe the semantics of the API.The combination of OOP and component technology is applied to realize the interoperability and seamless link between different applications. The Information Exchange Model (IEM) implemented by Extensible Markup Language (XML) will simplify and accelerate the data object standardization process. Furthermore, the problems, which may be encountered during the present development, are also discussed.
