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.
