Abstract

A device management system for a plurality of devices, including a data collecting device that acquires device data for one or more of the plurality of devices, and a transmission circuit that transmits the device data to a device management, wherein the device management station determines any outlying devices within the plurality of devices. Moreover, a device management method for a plurality of devices that includes acquiring device data for one or more of the plurality of devices, transmitting the device data to a device management station, generating a control chart on the basis of the transmitted device data, determining whether at least one of the plurality of devices is outside at least on of the upper limit and the lower limit, and providing an appropriate action to take on the basis of the determination.

Claims

1. A device management system comprising:

a data collecting device that collects operational data from a plurality of monitored devices; and

a statistical generating device that generates statistical norms of operation for a population of the plurality of monitored devices based on the collected operational data;

a selecting device that selects monitored devices having operational data that substantially varies from the generated statistical norms of operation; and

an I/O interface that transmits the statistical norms back to all of the monitored devices that have the operational data that substantially varies from the generated statistical norms of operation, wherein the statistical norms comprise a control chart that identifies a lower boundary, an upper boundary and a center line, and

the upper and lower boundaries are defined based on an analysis of the operational data from more than one of the monitored devices.

2. The system of claim 1, wherein the operational data comprises at least one of component level data, system level data, event level data, job level data, control data, environmental data, monitored device usage data, monitored device configuration data, monitored device malfunction data, or monitored device repair data.

3. The system of claim 1, wherein the operational data is acquired in one or more operational modes of the plurality of monitored devices, including at least one of a normal mode, a diagnostic mode, a failed mode or a limp-along mode.

4. The system of claim 1, wherein the operational data is data relative to one or more modules comprised within the device.

5. The system of claim 1, further comprising a repair planning device that determines an appropriate action based on the operational data;

wherein the appropriate action comprises at least one of an autonomous repair, a customer type repair, a customer service engineer type repair, and a report to a user.

6. The system of claim 1, wherein the data collecting device collects operational data over at least one of a LAN, a WAN or a wireless network.

7. The system of claim 1, wherein local diagnostics and population diagnostics are derived on the basis of the statistical norms.

8. The system of claim 1, wherein at least one of the lower boundary and the upper boundary is equal to three times a standard deviation of the plurality of monitored devices.

9. The system of claim 1, wherein the plurality of monitored devices comprise at least one of electro-mechanical devices, electronic devices, mechanical devices, or a combination thereof.

10. The system of claim 1, wherein the selecting device selects monitored devices that exhibit operational data located at more than three times a standard deviation from the center line.

11. The system of claim 1, wherein the selecting device selects monitored devices that exhibit operational data located outside at least one of the upper boundary or the lower boundary.

12. A device management method comprising:

collecting operational data from a plurality of monitored devices;

generating statistical norms for the plurality of monitored devices based on the collected operational data;

selecting monitored devices that have operational data that substantially varies from the generated statistical norms; and

transmitting the statistical norms back to all of the monitored devices that have the operational data that substantially varies from the generated statistical norms via an I/O interface, wherein generating statistical norms comprises generating a control chart that identifies a lower boundary, an upper boundary and a center line for the plurality of monitored devices, and

the upper and lower boundaries are defined based on an analysis of the operational data from more than one of the monitored devices.

13. The method of claim 12, wherein collecting operational data comprises collecting at least one of component level data, system level data, event level data, job level data, control data, environmental data, monitored device usage data, monitored device configuration data, or monitored device repair data.

14. The method of claim 12, wherein collecting operational data is performed in one or more modes of operation of the plurality of monitored devices, including at least one of a normal mode, a failed mode or a limp-along mode.

15. The method of claim 12, wherein collecting operational data comprises collecting data relative to one or more modules comprised in the monitored devices.

16. The method of claim 12, wherein selecting monitored devices comprises selecting monitored devices that exhibit operational data located at more than three times a standard deviation from the center line.

17. The method of claim 12, wherein selecting monitored devices comprises selected monitored devices that exhibit operational data located outside at least one of the upper boundary or the lower boundary.

18. The method of claim 12, further comprising taking appropriate action on at least one of the plurality of monitored devices.

19. The method of claim 18, wherein the appropriate action comprises at least one of an autonomous repair of the monitored devices, a customer type repair of the monitored devices, a customer service engineer type repair of the monitored devices, or a report to a user of the monitored devices.

20. An information storage medium embodied on a recordable medium, the storage medium comprising instructions to perform the device management method of claim 12.

21. A device management system, comprising:

means for collecting operational data from a plurality of monitored devices;

means for generating statistical norms for the plurality of monitored devices based on the collected operational data;

means for selecting monitored devices that have operational data that substantially varies from the generated statistical norms; and

means for transmitting the statistical norms back to all of the monitored devices that have the operational data that substantially varies from the generated statistical norms, wherein generating statistical norms comprises generating a control chart that identifies a lower boundary, an upper boundary and a center line for the plurality of monitored devices, and

the upper and lower boundaries are defined based on an analysis of the operational data from more than one of the monitored devices.
