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 dynamic alarm threshold design and alarm cancel method and system; the method dynamically set a corresponding alarm threshold according to differences of sample points, and determines an adjusting variable of the corresponding abnormal point, thus reducing wrong alarms and missing alarms in an industrial alarm system, preventing operators from being drown in massive interference alarms, allowing operators to timely find useful alarms, assisting operators to react on generated alarms, and guiding them to cancel alarms.

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...
