Research On Alarm & Event Of Real-Time Database

Real-Time Database (RTDB) is the result of the integration of traditional database technologies and real-time systems, and it's the core of the supervisory information system (SIS). It acts as an essential role in many industrial fields and thus is very significant and valuable to research and practice. Alarm and event is the important component of Real-time database, and it ensures the monitoring system run at a safe and stable state. The mission that this article wants to solve is how to develop an alarm and event processing system in industrial control field. First the article introduces producing background, main characteristics and the frame of system of real-time database. Second the article analysis on system architecture of real-time database, designs of the frame of alarm and event processing system and its interface, Alarm and event information properties, then immediately introduces how to design alarm and event information storage and publish/subscribe, alarm acknowledge, etc., and this is the core of this paper. Finally the article introduces application of alarm and event processing subsystem in supervisory information system, alarm and event information remote publication by latest technology.
