It becomes more difficult to manage, integrate and share the control system real-time data when we set up the industrial real-time database because of complicated affair between every department and isomeric character of the system. A three-level-structure model and the method to establish database is provided based on CORBA criterion with its character of being regardless of programming languages, hardware platform and network protocol . A universal real-time database faces multi-system is also set up by learning the distributed criterion, it can realize the request broker , and the application software can visit the database pellucidly ; Thus the power station simulation model can be linked with the control system such as infi90 , ovation and be made use of the control object , a closed simulation and control experiment system is set up. Further more we can build an integrate automatic experiment platform from the simulation object of power plant to the process control and the to SIS.

在创建工控领域实时数据库时，企业各部门间的复杂事务及内部异构性给实时数据的管理、集成和共享带来了一定的困难，根据CORBA规范具有语言无关性、平台无关性和网络协议无关性的特点提出基于分布式计算规范CORBA的三层体系结构模型及建立与维护实时数据库的方法和途径；通过CORBA规范建立面向多个分散控制系统的通用实时数据库，实现数据访问代理，使应用软件可以透明地对实时数据库进行访问、存取、管理；将Infi90、Ovation分散控制系统与火电厂仿真机模型进行有效的互连，以全物理过程仿真数学模型为对象，构建了闭环控制仿真实验研究系统，实现数据的高效连通及管理；进而通过基于CORBA的实时数据库构建一个从火电厂仿真机对象到过程控制设备再到SIS系统的综合自动化试验平台。
