Abstract
A method for managing alarms in a distributed control system, wherein the method comprises the following steps: monitoring at least one process parameter, activating an alarm when the process parameter exceeds an alarm threshold, deactivating an alarm when the process parameter no longer exceeds the alarm threshold, and determining by an AI based alarm control system before the alarm is activated at least one predicted alarm information, which comprises information about whether the alarm threshold will be exceeded.
Claims14
A method for managing alarms in a distributed control system, the method comprising:
- monitoring at least one process parameter;
- activating an alarm when the process parameter exceeds an alarm threshold;
- deactivating an alarm when the process parameter no longer exceeds the alarm threshold;
- and
- determining by an AI based alarm control system before the alarm is activated at least one predicted alarm information, which comprises information about whether the alarm threshold will be exceeded.
A system for managing alarms in a distributed control system, wherein the system comprises:
- a process parameter monitor configured to monitor at least one process parameter;
- an alarm control configured to activate an alarm when the process parameter exceeds an alarm threshold and to deactivate the alarm when the process parameter no longer exceeds the alarm threshold;
- an AI based alarm control system configured to determine at least one predicted alarm information before the alarm is activated, the AI based alarm control system comprising information about whether the alarm threshold will be exceeded.
