Abstract

A method includes receiving, by a first wireless device integrated into a management facility from a second wireless device integrated into a detection device, environmental conditions produced by a structure and detected by the detection device attached to the structure; and processing, by the management facility, the environmental conditions to detect a deviation from an expected operation of the structure.

First claim

What is claimed is:

1 . A method, comprising:
receiving, by a first wireless device integrated into a management facility from a second wireless device integrated into a detection device, environmental conditions produced by a structure and detected by the detection device attached to the structure; and processing, by the management facility, the environmental conditions to detect a deviation from an expected operation of the structure.

2 . The method of claim 1 , wherein the detection device is an accelerometer and the structure is an air cycle machine.

3 . The method of claim 1 , wherein the detection device operates in a low power mode;
wherein the detection device operates in a full power mode in response to an occurrence of a first event; and wherein the detection device samples and stores the environmental conditions produced by the structure when in full power mode.

4 . The method of claim 1 , wherein the deviation from the expected operation indicates a vibration by the air cycle machine.

5 . The method of claim 1 , further comprising:
triggering a servicing of the structure in response to detecting the deviation from the expected operation by sending the deviation to a health and usage management system, the servicing corresponding to a type of the fatigue failure associated with the deviation.

6 . The method of claim 1 , further comprising:
instructing the structure to operate in safe mode in response to detecting the deviation from the expected operation.

7 . The method of claim 1 , wherein the deviation is one of a plurality of deviation from the expected operation of the structure.

8 . A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause:
receiving, by a first wireless device integrated into a management facility from a second wireless device integrated into a detection device, environmental conditions produced by a structure and detected by the detection device attached to the structure; and processing, by the management facility, the environmental conditions to detect a deviation from an expected operation of the structure.

9 . The computer program product of claim 8 , wherein the detection device is an accelerometer and the structure is an air cycle machine.

10 . The computer program product of claim 8 , wherein the detection device operates in a low power mode;
wherein the detection device operates in a full power mode in response to an occurrence of a first event; and wherein the detection device samples and stores the environmental conditions produced by the structure when in full power mode.

11 . The computer program product of claim 8 , wherein the deviation from the expected operation indicates a vibration by the air cycle machine.

12 . The computer program product of claim 8 , the program instructions further executable by the processor to cause:
triggering a servicing of the structure in response to detecting the deviation from the expected operation by sending the deviation to a health and usage management system, the servicing corresponding to a type of the fatigue failure associated with the deviation.

13 . The computer program product of claim 8 , the program instructions further executable by the processor to cause:
instructing the structure to operate in safe mode in response to detecting the deviation from the expected operation.

14 . The computer program product of claim 8 , wherein the deviation is one of a plurality of deviation from the expected operation of the structure.
