Claim 2:
3. The method according to claim 2, of which in step 3:
in case the parent alarm is detected first and has a new status, then the child alarm is detected, because the child alarm is the consequence of the parent, it will be filtered out, the system only keeps the parent alarm;
in case the child alarm is detected first and has new status, then the parent alarm is detected, the system will still filter out the alarm that comes first as the child alarm and keep the later alarm as the parent alarm;
in the case that the parent alarm changes to cleared state before the child alarm, the present invention proposes the following modes of handling the child alarm:
KEEPING mode: when the parent alarm goes to cleared state, then the system will consider the child's status after a period of time after the parent alarm is cleared, then if the child alarm still hasn't changed to cleared the system state will display a child alarm; This is called a non-tight relationship;
FORCED_DELETED mode: in this way it works alarm the child will be forced to go to cleared state and end its life cycle; This is called a close relationship;

in case the child alarm changes to the cleared state before the parent alarm, it will not affect the state of the parent alarm, the parent alarm will still be displayed on the operating interface.
