基于CIM的SCADA系统实时数据库模型设计实现

Design and Implementation of SCADA System Real-time Database Based on CIM

实时数据库是SCADA系统的支撑平台乃至整个系统的核心内容,是构建其他子系统的基础。在研究CIM标准的基础上,结合SCADA系统实时数据库的特点,提出基于CIM设计SCADA系统实时数据库模型。设计出对应此模型的一种数据库结构模式,并在对象关系型数据库Postgresql中实现;研究了面向对象持久层技术,采用了Hibernate持久层框架的系统实现方案,并阐述了面向对象设计模型向关系型数据库映射的过程。最后根据以上设计,实现了一套新型的SCADA系统实时数据库,并且通过测试,验证了该系统的可行性。

The real-time database is the support platform of the SCADA system and even the core of the whole system. On the basis of CIM standard and combining with the SCADA characteristics, this paper presents a design of SCADA database model. The database scheme corresponding to the model is implemented using Postgresql. The paper employs the technique of object-oriented persistent layer and presents a description of how to mapping object-oriented elements to real-time database. Finally, a new SCADA system real-time database is implemented and proved feasible.
