Problems solved by technology
[0003] However, due to various reasons in the production process, it will cause nuisance alarms in production alarms
When there are a large number of these alarms, for the operator, not only the purpose and function of the alarm cannot be achieved, but the alarm is equivalent to being invalid. The repeated pop-up of the alarm has caused interference to the normal operation of the operator, which is not conducive to the safe operation of the production process.

The invention discloses a nuisance alarm suppression method and device, and the method comprises the steps: obtaining the first alarm information of a to-be-generated first alarm, and determining whether the first alarm belongs to a first type of alarm or not according to the first alarm information, wherein the first type of alarms comprise A type alarms capable of correlating to cause one or more sub-alarms, B type alarms repeatedly appearing in a first preset time period, C type alarms judged as invalid alarms, and D type alarms of which the appearing frequency is greater than or equal to a preset frequency threshold in a second preset time period; when the first alarm belongs to the A-type alarm, executing the first alarm, and determining a sub-alarm corresponding to the first alarm from an alarm suppression configuration table as a nuisance alarm for suppression; and when it is determined that the first alarm belongs to a B-type alarm, a C-type alarm or a D-type alarm, directly using the first alarm as a nuisance alarm for suppression. According to the scheme of the embodiment, nuisance alarm is effectively restrained, the warning effect of alarm is enhanced, and safe and stable operation of a unit is guaranteed.
Description
technical field [0001] This article relates to production alarm technology, especially a method and device for suppressing nuisance alarm. Background technique [0002] During normal production operation (such as power generation operation), the alarms of each system of the unit are pushed to the operator through the alarm light plate. When an alarm occurs, the alarm light plate will pop up to remind the operator, so that the operator can find out in time, Deal with problems, prevent major accidents such as equipment damage or even unit shutdown, and ensure the safe operation of the unit. [0003] However, due to various reasons in the production process, it will cause nuisance alarms in production alarms. When there are a large number of these alarms, for the operator, not only the purpose and function of the alarm cannot be achieved, but the alarm is equivalent to being invalid. The repeated pop-up of the alarm has caused interference to the normal operation of the operat...
