Problems solved by technology

However, due to the influence of external disturbances such as noise and the lack of consideration of the correlation between variables, the industrial alarm system will generate a large number of false alarms and missed alarms, which will seriously affect the performance of the industrial alarm system, not only leading to useful The alarm information is submerged, and because of the "wolf is coming" effect, the operators ignore the alarm information for a long time, distrust or even shut down the industrial alarm system

Abstract

The invention discloses a method and system for dynamic alarm threshold design and alarm elimination. The invention dynamically sets corresponding alarm thresholds according to the differences of each sample point and determines the adjustment variables of corresponding abnormal points, thereby reducing the number of alarms in the industrial alarm system. False alarms and missed alarms prevent operators from being overwhelmed by a large number of disturbing alarms, which is convenient for operators to find real useful alarms in time, and the invention is beneficial to help operators respond to alarms that have occurred and guide them how to eliminate them. Call the police.

Description

technical field [0001] The invention relates to the field of automation technologies such as industrial alarm systems, in particular to a method and system for dynamic alarm threshold design and alarm elimination. Background technique [0002] The alarm system is an important part of the modern industrial system and plays a vital role in the safe and efficient operation of the production process. Therefore, the research on the industrial alarm system has received more and more attention from the industry and academia. However, due to the influence of external disturbances such as noise and the lack of consideration of the correlation between variables, the industrial alarm system will generate a large number of false alarms and missed alarms, which will seriously affect the performance of the industrial alarm system, not only leading to useful The alarm information is submerged, and because of the "wolf is coming" effect, the operators ignore the alarm information for a lon...
