Abstract
The invention relates to an alarm management apparatus for managing an alarm occurring in a plant. The alarm management apparatus includes an alarm collection unit for collecting an alarm; a process data collection unit for collecting process data; an alarm suppression determination unit for determining whether or not suppressing an alarm from an alarm suppression target is adequate using the process data upon reception of an alarm suppression command; and an alarm processing unit for suppressing the alarm from the alarm suppression target if the alarm suppression determination unit determines that the alarm suppressing is adequate.
Claims8
An alarm management apparatus for managing an alarm occurring in a plant, said alarm management apparatus comprising:
- a computer configured to operate as
- an alarm collection section which collects an alarm;
- an alarm engineering section via which an operator sets an alarm suppression condition that is used to determine whether an alarm is to be suppressed;
- an input section via which an operator inputs an alarm suppression command specifying that an alarm from at least one alarm suppression target is to be suppressed;
- a process data collection section which collects process data;
- an alarm suppression determination section which determines, in response to reception of the alarm suppression command, whether or not the process data collected by the process data collection section satisfies the alarm suppression condition;
- and
- an alarm processing section which suppresses the alarm from the at least one alarm suppression target,
- wherein the alarm suppression determination section permits the alarm processing section to suppress the alarm specified by the alarm suppression command input by the operator in response to determining that the process data collected by the process data collection section satisfies the alarm suppression condition, and
- the alarm suppression determination section does not permit the alarm processing section to suppress the alarm specified by the alarm suppression command input by the operator in response to determining that the process data collected by the process data collection section does not satisfy the alarm suppression condition.
