Abstract

The scheduling of maintenance for operational equipment is disclosed in which the operational equipment is distributed over many locations. Operational data relating to the use of operational equipment is received, along with equipment failure data. Stored operational data (501) is analysed (503) in combination with stored operational equipment failure data (502) to determine performance information (504) relating to extensive use of the operational equipment to rates of failure of operational equipment. New operational data is processed (505) along with equipment failure data in combination with the relationship information (504) to produce knowledge based output alert (506 to 509) and maintenance schedules (510).

Claims

1. A method of scheduling the maintenance of operational equipment distributed over a plurality of locations, comprising the steps of:

receiving operational data relating to use of operational equipment;

receiving operational equipment failure data;

analysing said operational data in combination with said operational equipment failure data to determine performance information relating extent of use of said operational equipment to rates of failure of operational equipment; and

processing new operational data and operational equipment failure data in combination with said relationship information to produce knowledge-based output alerts and maintenance schedules.

2. The method of claim 1, wherein performance information is determined upon receipt of an operational equipment failure datum.

3. The method of claim 2, wherein an average extent of use to failure value is calculated as part of said performance information.

4. The method of claim 3, wherein a variance is calculated as part of said performance information.

5. The method of claim 3, wherein a minimum extent of use to failure is calculated and a maximum extent of use to failure is calculated.

6. The method of claim 1, wherein new operational data is processed upon receiving a new operational equipment failure datum and a failure record is added to a failure table.

7. The method of claim 6, wherein said failure record identifies an equipment type, a manufacturer, a location and a maintenance team responsible for maintenance.

8. The method of claim 1, further comprising the steps of:

processing said failure table to produce an equipment alert;

processing said failure table to produce a manufacturer alert;

processing said failure table to produce a geographical alert; and

processing said failure table to produce a maintenance alert.

9. The method of claim 1, further comprising the step of producing a maintenance schedule identifying a list of maintenance operations to be performed over a predetermined period of time.

10. The method of claim 1, wherein said maintenance schedule is produced by:

selecting an item of operational equipment;

reviewing stored operational data for the selected item of operational equipment;

assessing an extent of usage of the selected item of operational equipment since last maintained; and

selecting a period for the next maintenance activity to be performed.

11. The method of claim 9, wherein a maintenance table is produced identifying equipment followed by a maintenance period and said maintenance schedule is produced from said maintenance table showing maintenance periods followed by location followed by an identification of the equipment.

12. The method of claim 9, wherein said maintenance schedule alert is produced with reference to a service level agreement.

13. An apparatus for scheduling the maintenance of operational equipment distributed over a plurality of locations, comprising:

first storage for storing operational data identifying use of operational equipment;

second storage for storing equipment failure data for said operational equipment; and

at feast one data analysis processor configured to analyse said operational data in combination with said equipment failure data to determine performance information relating extent of use of said operational equipment to rates of failure of said operational equipment;

third storage for said performance information; and

at least one data monitoring processor configured to monitor new operational data and new equipment failure data with reference to said performance data to produce knowledge-based output alerts and maintenance schedules.

14. The apparatus of claim 13, wherein each said operational equipment includes at least one electric motor and said real-time operational data identifies activations of some or all of said electric motors.

15. The apparatus of claim 14, wherein said operational equipment includes operational mechanics driven by said electric motors and said operational equipment failure data includes data relating to failure of said electric motors and failure of said operational mechanics.

16. The apparatus of claim 13, including a data collector located at each item of operational equipment.

17. The apparatus of claim 16 including a data gateway at each geographical location, wherein data collectors communicate with said data gateway by radio data transmission.

18. The apparatus of claim 16, wherein said data collectors store and forward packets of data, wherein each said packet of data includes an identification of the respective item of operational equipment, data relating to the operation of said operational equipment and a number identifying the position of the packet in a sequence of transmitted packets.

19. A maintenance schedule identifying work intervals, geographical locations within said work intervals and operational equipment to be maintained within each said geographical locations, wherein said maintenance schedule is produced periodically by performing the steps of:

reviewing stored operational data indicating operations performed by said operational equipment;

calculating an extent of use for an item of operational equipment; and

identifying the next work interval during which a maintenance activity will be required.

20. The maintenance schedule of claim 19, wherein said step of identifying the next work interval is performed with reference to an agreed service level.
