基于主动数据库分布式SCADA设计与实现

Design and implementation of distributed SCADA system based on active database

传统模式无法满足SCADA系统对主动数据服务的要求,针对SCADA系统的数据实时性、准确性需求,结合主动数据库技术,提出了基于主动数据库的分布式SCADA系统结构。同时针对SCADA系统与其他异构系统之间的集成和数据交互问题,将基于发布/订阅的消息模式引入系统中,从而降低与其他系统之间的依赖性,增强系统的可扩展性,并给出了主动数据库模型和实时消防监测报警系统的具体应用实例。

The traditional models cannot meet the needs of active data services for SCADA system.According to the real-time and accuracy requirements of data,also combining the active database technology,a distributed SCADA system architecture based on active database is proposed.At the same time,considering the integration and data exchange issues between the SCADA and other heterogeneous systems,the messaging model based on the publish/subscribe is introduced into the system,so that the dependency on other systems is reduced,the system scalability is enhanced.The application examples of active database model and real-time monitoring system for fire alarm are also introduced.
