Abstract

An Interactive Maintenance Management System (“IMMS”) (10) is an alarm handling system (FIG. 2) for handling alarms (102) that indicate present or imminent equipment failure. The IMMS (10) may be utilized in industrial situations, such as strip-mines (14), to reduce equipment (12) downtime and reduce or prevent equipment failure. The IMMS (10) utilizes a flexible response system to track, analyze, and improve performance of the alarm handling system.

Claims

1. A method of handling equipment failure alarms comprising the steps of:

receiving an alarm from a transceiver coupled to a heavy vehicle, the heavy vehicle including at least one of a dozer, drill, haul truck, loader and shovel, said alarm indicating a state of at least one of a component and a system of the heavy vehicle, the state being defined by at least one of an alarm generator located on the at least one of a component and a system, an excavation record, a dump record, and an equipment status time, the alarm including an abnormal event identifier and at least one of an equipment identifier, a location, and an equipment operator identification;

storing the received alarm in a database;

evaluating whether a notification of the received alarm should be sent to a third party maintenance organization;

when notification of the received alarm should be sent to a third party maintenance organization, sending an alarm packet describing the received alarm to the third party maintenance organization;

determining that the alarm has not been snoozed by examining a status identifier of the alarm, wherein said status identifier indicates whether an alarm notification is temporarily suppressed;

analyzing the alarm, by;

identifying a minimum health factor for at least one of the component and system of the heavy vehicle,

identifying an occurrence frequency of the alarm,

determining whether the minimum health factor for the at least one of the component and system of the heavy vehicle has been violated, and

using the determination of whether the minimum health factor has been violated and the occurrence frequency of the alarm to determine whether the alarm is to be snoozed; and

when the alarm is not to be snoozed, displaying the alarm for action or information.

2. A method of handling equipment failure alarms comprising the steps of:

receiving an alarm from a transceiver coupled to a heavy vehicle, said alarm indicating a state of at least one of a component and a system of the heavy vehicle, the state being defined by at least one of an alarm generator located on the at least one of a component and a system, an excavation record, a dump record, and an equipment status time, the alarm including an abnormal event identifier and at least one of an equipment identifier, a location, and an equipment operator identification;

storing the received alarm in a database;

determining that the alarm has not been snoozed by examining a status identifier of the alarm, wherein said status identifier indicates whether an alarm notification is temporarily suppressed;

analyzing the alarm, by;

determining an availability of a maintenance facility to repair the at least one of a component and a system of the heavy vehicle,

identifying a minimum health factor for at least one of the component and system of the heavy vehicle, and

using the minimum health factor and the availability of the maintenance facility to determine whether the alarm is to be snoozed;

when the alarm is to be snoozed, setting snooze criteria based upon the availability of the maintenance facility; and

when the maintenance facility is available, releasing the alarm.

3. The method of claim 2, further comprising the step of displaying the alarm for action or information, wherein said displaying step follows the step of determining that the alarm has not been snoozed and precedes the step of analyzing the alarm.

4. The method of claim 3, including:

identifying a consequence based upon the abnormal event identifier;

determining whether a repair record is to be created using the consequence;

when a repair is to be created, creating a repair record; and

snoozing the alarm, wherein said steps of determining that a repair record is to be created and creating a repair record follow analyzing the alarm and precede the step of snoozing the alarm.

5. The method of claim 4, further comprising the step of determining that said alarm is not to be ignored, wherein said determining that said alarm is not to be ignored step follows the analyzing the alarm step and precedes the snoozing the alarm step.

6. The method of claim 5, further comprising the step of sending the alarm to an analyst, wherein said sending step follows the step of determining that the alarm has not been snoozed and precedes the step of determining that said alarm is not to be ignored.

7. The method of claim 6, further comprising the steps of:

determining that the alarm is to be sent to a third-party; and

sending said alarm to said third-party;

wherein said determining that the alarm is to be sent to a third-party step follows the step of determining that the alarm has not been snoozed.

8. The method of claim 4, further comprising the steps of:

ignoring said alarm; and

documenting the reason for ignoring said alarm, wherein said ignoring step and said documenting steps follow the analyzing the alarm step and precedes the snoozing the alarm step.

9. The method of claim 8, further comprising the step of sending the alarm to an analyst, wherein said sending step follows the step of determining that the alarm has not been snoozed and precedes the step of ignoring said alarm.

10. The method of claim 9, further comprising the steps of:

determining that the alarm is to be sent to a third-party; and

sending said alarm to said third-party;

wherein said determining that the alarm is to be sent to a third-party step follows the step of determining that the alarm has not been snoozed.

11. The method of claim 4, further comprising the step of sending the alarm to an analyst, wherein said sending step follows said determining that the alarm has not been snoozed and precedes the step of displaying the alarm for action or information.

12. The method of claim 11, further comprising the steps of:

determining that the alarm is to be sent to a third-party; and

sending said alarm to a third-party;

wherein said determining that the alarm is to be sent to a third-party step follows the step of determining that the alarm has not been snoozed.

13. The method of claim 2, wherein the step of setting snooze criteria comprises selecting snooze duration based on a predetermined time value, wherein said selecting snooze duration step follows said determining that the alarm is to be snoozed step and precedes the step of determining that at least one of the snooze criteria has been violated, and wherein the step of determining that at least one of the snooze criteria has been violated comprises determining that said predetermined time value has been exceeded.

14. The method of claim 2, further comprising the step of selecting parameters to monitor and rules to establish severity limits, wherein said selecting parameters and rules step follows said determining that the alarm is to be snoozed step and precedes the step of determining that at least one of the snooze criteria has been violated.

15. The method of claim 2, wherein the step of setting snooze criteria comprises selecting an event to act as a trigger, wherein said selecting event step follows said determining that the alarm is to be snoozed step and precedes the step of determining that at least one of the snooze criteria has been violated, and wherein the step of determining that at least one of the snooze criteria has been violated comprises determining that said event has occurred.

16. The method of claim 2, wherein the step of setting snooze criteria comprises selecting user defined criteria to act as a trigger, wherein said selecting user defined criteria step follows said determining that the abnormal event is to be snoozed step and precedes the step of determining that at least one of the snooze criteria has been violated, and wherein the step of determining that at least one of the snooze criteria has been violated comprises determining that said user defined criteria have been satisfied.

17. A method of handling equipment failure alarms comprising the steps of:
