Sensor based system and method for drift analysis to predict equipment failure
First Claim
1. A computer program product tangibly stored on a non-transitory computer readable hardware storage device, the computer program product for forming predictions of when equipment service is coming due or when equipment is about to fail, the computer program product comprising instructions to cause a processor to:
- collect sensor information from plural sensors deployed in a premises with sensor information including a sensor data value, an identity of the premises, and identity of a physical item of equipment being monitored by the plural sensors in the identified premises;
convert the sensor signals into semantic representation of sensor states;
continually analyze the collected sensor information by applying one or more unsupervised learning models to the sensor states to determine normal sensor states and drift sensor states, with respect to equipment service of the physical item of equipment;
retrieve one or more predefined sensor state sequences that correspond to drift sensor states;
detect during the continual analysis of the sensor states by comparing the determined drift sensor states to the retrieved sensor state sequences, presence of a detected drift sensor state that corresponds to a state that equipment service is due or the physical item of equipment is about to fail in its operation;
determine a prediction based on the detected drift sensor state; and
send the prediction to an external device.

Abstract
Techniques for detecting physical conditions at a physical premises from collection of sensor information from plural sensors execute one or more unsupervised learning models to continually analyze the collected sensor information to produce operational states of sensor information, produce sequences of state transitions, detect during the continual analysis of sensor data that one or more of the sequences of state transitions is a drift sequence, correlate determined drift state sequence to a stored determined condition at the premises, and generate an alert based on the determined condition. Various uses are described for these techniques.
