Abstract

A method for analyzing the condition of a machine, and an apparatus for analyzing the condition of a machine are described.

Claims (44)

1. A method of monitoring an operating condition status of a machine that includes a rotating component, the method comprising:

obtaining signal data from a vibration sensor in proximity to the rotating component, said vibration sensor coupled with a portable first computing device;

performing signal processing of the obtained signal data with the first computing device prior to transmission, said signal processing comprising:

determining a first condition value corresponding to a first predetermined occurrence rate based on the obtained signal data;

determining a second condition value corresponding to a second predetermined occurrence rate based on the obtained signal data;

monitoring a first change in the first condition value;

monitoring a second change in the second condition value;

determining a first indication for an amount of lubrication for the rotating component based on the monitored first change and the second change; and

determining a second indication of mechanical damage distinct from a lubrication damage based on a change in relation between the first condition value and the second condition value; and

transmitting, over a wireless connection, the first indication and the second indication to a second computing device.

2. The method according to claim 1 , wherein the second predetermined occurrence rate is higher than the first predetermined occurrence rate.

3. The method according to claim 1 , wherein the signal processing comprises processing the obtained signal data in time domain.

4. The method according to claim 1 , wherein the signal processing comprises processing the obtained signal data in frequency domain.

5. The method according to claim 1 , wherein said second computing device is configured to display an operating condition status of the machine based on the determined first indication and the determined second indication.

6. The method according to claim 1 , wherein the second computing device comprises a server.

7. The method according to claim 1 , wherein the second computing device comprises a portable computing device.

8. The method according to claim 1 , wherein the first condition value is indicative of amplitude of peak values at the first predetermined occurrence rate.

9. The method according to claim 1 , wherein the second condition value is indicative of amplitude of peak values at the second predetermined occurrence rate.

10. A computing device for monitoring an operating condition status of a machine that includes a rotating component, said computing device comprising one or more hardware processors configured to:

receive signal data from a vibration sensor in proximity to the rotating component;

determine a first condition value corresponding to a first predetermined occurrence rate based on the received signal data;

determine a second condition value corresponding to a second predetermined occurrence rate based on the obtained signal data;

monitor a first change in the first condition value;

monitor a second change in the second condition value;

determine a first indication for an amount of lubrication for the rotating component based on the monitored first change and the second change;

determine a second indication of mechanical damage distinct from the lubrication damage based on a change in relation between the first condition value and the second condition value; and

transmit, over a wireless connection, the first indication and the second indication to a second computing device.

11. The computing device of claim 10 , wherein the second predetermined occurrence rate is higher than the first predetermined occurrence rate.

12. The computing device of claim 10 , wherein the one or more hardware processors are further configured to process the obtained signal data in time domain.

13. The computing device of claim 10 , wherein the one or more hardware processors are further configured to process the obtained signal data in frequency domain.

14. The computing device of claim 10 , wherein said second computing device is configured to display an operating condition status of the machine based on the determined first indication and the determined second indication.

15. The computing device of claim 10 , wherein the second computing device comprises a server.

16. The computing device of claim 10 , wherein the second computing device comprises a portable computing device.

17. The computing device of claim 10 , wherein the first condition value is indicative of amplitude of peak values at the first predetermined occurrence rate.

18. The computing device of claim 10 , wherein the second condition value is indicative of amplitude of peak values at the second predetermined occurrence rate.

19. A non-transitory physical computer storage comprising computer-executable instructions stored thereon that, when executed by one or more processors, are configured to implement a process comprising:

performing signal processing of signal data obtained from a first sensor coupled with a portable first computing device prior to transmission, said signal processing comprising:

determining a first condition value corresponding to a first predetermined occurrence rate based on the obtained signal data;

determining a second condition value corresponding to a second predetermined occurrence rate based on the obtained signal data,;

monitoring a first change in the first condition value;

monitoring a second change in the second condition value;

determining a first indication for an amount of lubrication for a rotating component based on the monitored first change and the second change; and

determining a second indication of mechanical damage distinct from a lubrication damage based on a change in relation between the first condition value and the second condition value; and

transmitting, over a wireless connection, the first indication and the second indication to a second computing device.
