Abstract

A system comprising at least one piece of equipment; a plurality of sensors adapted to measure one or more operating parameters of the equipment; and a signature generator adapted to encode a plurality of data streams from the sensors into an operating signature for the equipment.

Claims

1. A system comprising:

at least one piece of equipment;

a plurality of sensors adapted to measure one or more operating parameters of the equipment; and

a signature generator adapted to encode a plurality of data streams from the sensors into an operating signature for the equipment.

2. The system of claim 1, further comprising:

a signature repository containing a number of signatures that correspond to known operating conditions of the equipment.

3. The system of claim 2, further comprising:

an action repository containing a number of actions to be taken which correspond to the signatures in the signature repository.

4. The system of claim 2, further comprising:

a signature analyzer adapted to compare a signature from the signature generator with a known signature from the signature repository.

5. The system of claim 2, further comprising:

an event engine adapted to take a predetermined action when a signature from the signature generator matches a known signature from the signature repository.

6. The system of claim 1, wherein:

the signature generator produces a signature comprising at least two of a high, normal, and low range bit string.

7. The system of claim 6, wherein:

the signature generator converts the bit string to a number.

8. A method comprising:

identifying at least one piece of equipment to be monitored;

installing a plurality of sensors to measure operating data of the equipment;

establishing an operating range for each of the sensors; and

creating an encoding key for each of the ranges.

9. The method of claim 8, further comprising:

converting a plurality of the encoding keys into an operating signature.

10. The method of claim 8, further comprising:

storing a plurality of known signatures in a database, the signatures corresponding to known operating conditions of the equipment.

11. The method of claim 10, further comprising:

storing a plurality of actions to take in a database, the actions corresponding to the known signatures.

12. The method of claim 9, further comprising:

comparing the operating signature with known signatures in the database.

13. The method of claim 12, further comprising:

taking a predetermined action when the operating signature matches a known signatures in the database.

14. The method of claim 9, further comprising:

storing a new signature in a database, the signature corresponding to an observed or measured operating condition of the equipment.

15. The method of claim 14, further comprising:

storing a new action in a database, the action corresponding to a new signature, the new action designed to correct observed or measured operating conditions of the equipment.
