摘　　要：介绍了主动数据库技术,分析了SCADA系统中的基本主动事件,给出了由基本事件运算构成复杂事件的方法。提出了在SCADA系统中实现主动实时数据库的途径,并据此构造了SCADA系统主动实时数据库模型。通过典型实例研究了基于此模型的具体应用。应用研究表明,采用主动实时数据库技术的SCADA系统具有较高的效率,并且数据库系统的性能大为提高。This paper describes the active real-time databases technology and analyzes the basic active events in the SCADA system. It is shown that complicated active events can be obtained by computing the basic active events. The method for implementing the active real-time database in the SCADA system is presented, and the model of an active real-time database in the SCADA system is also given using this method. Application based on this model is studied through a typical example. The result shows that the SCADA system based on active real-time databases has a higher efficiency and the database capability is greatly improved.
