Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046] In the implementation process of event processing described in the prior art, the control station should upload the collected field data, algorithm operation results and event numbers to the DCS for real-time processing tasks. Although the processing speed of the control station is very high, the event judgment on the control station undoubtedly reduces its processing efficiency. At the same time, the upload of the event number increases the network dat...

Abstract

The invention discloses an event-handling method and system of a distributed control system (DCS). The method comprises the following steps: a DCS server receives the variable data uploaded by a control station; and the DCS server judges whether the variable data generate a new event, and if so, the DCS server performs the corresponding treatment to the event according to preset event-handling rules. By using the method and system of the invention, the event-handling efficiency of the DCS can be increased.

Description

technical field [0001] The present invention relates to the technical field of industrial automation control, and more specifically, relates to an event processing method and system of a distributed control system. Background technique [0002] At present, DCS (Distributed Control System, Distributed Control System) has been widely used in nuclear power, thermal power, chemical industry and other fields. In these fields, real-time and accurate reporting of alarm events can timely notify the staff to rush to the scene to deal with problems and eliminate hidden dangers , to avoid safety accidents. At the same time, recording various events in detail and in a standardized manner can help operators monitor the operation of the system clearly and clearly, and quickly distinguish various events. And so on, it is not difficult to see that providing real-time, efficient, stable, and fully functional event processing technology is the central link in the real-time processing of data...
