PI数据库中建点技术的研究

Study on Point Building Technology in PI Database

介绍了厂级监控信息系统(SIS)及其数据库平台PI实时数据库、PI数据库中的数据流程以及PI数据库的建点技术。指出PI数据库中主要的3种类型的点需要不同的属性配置,重点论述了影响累积点的5项属性,最后讨论了PI数据库建点技术在实际工程中的运用。

The supervisory information system （SIS） and its database platform PI （plant information）real-time database, data flow and point building technology in PI database are introduced, it is pointed out and emphasized that main three types of points in PI database need different attributes setting,and the five attributes which affect totalizer points. The points building technic in practical uses at the last of this paper are discussed.
