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;

a pattern repository comprising a pattern, wherein the pattern comprises a first nested pattern and a second nested pattern; and

a signature analyzer configured to compare the operating signature to the pattern and perform an action based on the comparison

2. The system of claim 1, wherein the pattern further comprises a sequence definition defining an ordering of the nested patterns

3. The system of claim 1, wherein the first nested pattern comprises a classified signature and a frequency specifying a number of occurrences of the classified signature over time.

4. The system of claim 3 wherein the pattern further comprises a sequence definition defining an ordering of the nested patterns.
