基于实时数据库的水电机组远程监测中心设计和实现

Design and Implementation of Real-time Database Based Remote Monitoring Center for Hydropower Units

将实时数据库系统应用在水电机组远程监测诊断中心,通过设计分布式系统结构,将软硬件系统分为现地采集层、厂级集成层和中心发布层3层,并充分利用eDNA数据库软件的数据桥分布特性,采用多存储方式融合的数据同步存取策略,最终建立结构开放、功能可扩展的远程分布式水电机组监测中心,为集团公司远程全面掌握水电机组运行信息提供系统平台和数据依据。

Application of real-time database systems to remote monitoring diagnostic center of hydropower units is presented.Through the design of a distributed system architecture,the hardware and software system are divided into three layers such as： local acquisition layer,plant integration layer and center publishing layer.By taking advantage of the data bridge distributed characteristics of eDNA database system,a data synchronization and access strategy is made by using a variety of storage methods.Finally,a remote distributed monitoring center with open structure and extendible function for hydropower units is established.As a system platform,it can help Hydropower Corporation fully know remote operating informations of units.
