Abstract

In one embodiment, a multi-purpose sensor may couple to a machine operating in an industrial environment and include numerous sensors disposed within the multi-purpose sensor to acquire sets of data associated with the machine or an environment surrounding the machine. A first portion of the sets of data may include historical sensor measurements over time for each of the sensors, and a second portion of the sets of data may include sensor measurements subsequent to when the first portion is acquired for each of the sensors. A processor of the multi-purpose sensor may determine a baseline collective signature based on the first portion, determine a subsequent collective signature based on the second portion, determine whether the collective signatures vary, and generate signals when a variance exists. The signals may cause a computing device, a cloud-based computing system, and/or a control/monitoring device to perform various actions.

First claim

The invention claimed is:

1. A multi-purpose sensor configured to couple to a machine operating in an industrial environment, comprising:
a housing;
a plurality of sensors disposed within the housing of the multi-purpose sensor and configured to acquire a plurality of different types of sets of data associated with the machine or an environment surrounding the machine, wherein:
a first portion of the plurality of different types of sets of data comprises historical sensor measurements over time for each of the plurality of sensors; and
a second portion of the plurality of different types of sets of data comprises sensor measurements subsequent to when the first portion is acquired for each of the plurality of sensors; and

a processor disposed within the housing of the multi-purpose sensor and configured to communicatively couple to the plurality of sensors and configured to:
determine a baseline collective measurement signature for the plurality of sensors based on the first portion;
determine a subsequent collective measurement signature based on the second portion;
determine whether the subsequent collective measurement signature varies from the baseline collective measurement signature;
generate one or more signals in response to a variance existing between the subsequent collective measurement signature and the baseline collective measurement signature, wherein the one or more signals are configured to cause a computing device, a cloud-based computing system, a control/monitoring device, or some combination thereof in the industrial environment to perform a preventative action, diagnostic, predictive operation, or some combination thereof, and wherein the one or more signals comprises a command signal configured to adjust an operation of the machine; and
transmit the one or more signals to the computing device, the cloud-based computing system, the control/monitoring device, or some combination thereof.

2. The multi-purpose sensor of claim 1 , wherein the processor is configured to transmit the signals via an antenna.

3. The multi-purpose sensor of claim 1 , wherein:
the preventative action comprises an alert configured to cause the computing device, the control/monitoring device, or both to display the alert, to disable functionality of a software application running on the computing device, the control/monitoring device, or both, or some combination thereof;
the diagnostic comprises determining a cause for the variance; and
the predictive operation comprises determining potential effects of the variance on the machine or other industrial automation equipment.

4. The multi-purpose sensor of claim 1 , wherein the plurality of sensors comprise two or more of:
a gas sensor configured to measure properties of ambient air in the environment surrounding the machine, emissions from the machine, or both;
a temperature sensor configured to measure a temperature of the machine or the environment surrounding the machine;
a motion sensor configured to sense movement of an object;
a vibration sensor configured to measure a frequency of vibration of the machine; or
a sound sensor configured to measure sounds of the machine or the environment surrounding the machine.

5. The multi-purpose sensor of claim 1 , wherein the processor is configured to:
determine an expected range of data for at least one of the plurality of sensors based on the first portion;
receive a set of data acquired by the at least one of the plurality of sensors;
determine whether the set of data is within the expected range of data; and
generate the one or more signals when the set of data is not within the expected range of data.

6. The multi-purpose sensor of claim 1 , wherein determining whether the subsequent collective measurement signature varies from the baseline collective measurement signature comprises:
comparing each of the sensor measurements or signatures of the subsequent collective measurement signature to a respective historical sensor measurement or signature of the baseline collective measurement signature for each of the plurality of sensors and determining the variance by:
determining that more than a threshold number of the sensor measurements or signatures of the subsequent collective measurement signature vary from the respective historical sensor measurement or signature of the baseline collective measurement signature;
determining that one of the sensor measurements or signatures of the subsequent collective measurement signature varies from the respective historical sensor measurement or signature of the baseline collective measurement signature by a threshold amount; or

both.

7. The multi-purpose sensor of claim 1 , wherein the processor is configured to:
log the variance when the variance occurs; and
receive a reason for the variance.

8. The multi-purpose sensor of claim 1 , comprising a beacon patch configured to:
acquire information related to proximities of one or more devices within a distance with regard to the multi-purpose sensor using near field communication technology; and
transmit the information to the computing device.

9. The multi-purpose sensor of claim 1 , comprising a location beacon configured to send location data related to a location of the multi-purpose sensor, the machine, or both to the computing device, wherein the computing device is configured to determine directions to the multi-purpose sensor, the machine, or both based on the location data.

10. The multi-purpose sensor of claim 1 , wherein:
at least one of the plurality of sensors comprises a motion sensor configured to sense movement of an object and send data indicating movement of the object to the processor; and
wherein the processor is configured to:
determine a location of the object relative to the machine based on the data; and
cause one or more operations of the machine to be unavailable when the object is within a distance relative to the machine.

11. The multi-purpose sensor of claim 1 , wherein:
at least one of the plurality of sensors comprises a motion sensor configured to sense movement of an object and send data indicating movement of the object to the processor; and
wherein the processor is configured to:
determine a location of the object relative to the machine based on the data; and
cause one or more operations of the machine to be available only when the object is within a distance relative to the machine.

12. A system, comprising:
a machine configured to operate in an industrial environment; and
a multi-purpose sensor configured to couple to the machine, wherein the multi-purpose sensor comprises:
a housing;
a plurality of sensors disposed within the housing of the multi-purpose sensor and configured to acquire a plurality of different types of sets of data associated with the machine or an environment surrounding the machine, wherein:
