Patent Number: 
Section: claims

1. A system for maintaining intelligent assets, comprising:a processor; anda memory connected to the processor, wherein the memory is encoded with instructions and wherein the instructions comprise:instructions for a work performance acquisition module to obtain work performance data comprising workload accomplished by the intelligent assets from a device operation production control system;instructions for a status monitoring module to obtain operation status data comprising power consumption of the intelligent assets;instructions for a loss calculation module to calculate a first ratio between the workload accomplished by the intelligent assets and the power consumption, and to calculate a loss degree of the intelligent assets according to said first ratio and a second ratio between a workload accomplished by the intelligent assets and the power consumption at an initial time, wherein an initial time comprises when the intelligent assets are just put into operation; andinstructions for a maintenance determining module to determine whether the intelligent assets need maintenance according to the loss degree of the intelligent assets. 2. The system of claim 1, wherein when the loss degree of the intelligent assets is greater than a predetermined threshold, instructions for the maintenance determining module to determine that the intelligent assets need maintenance. 3. The system of claim 1, further comprising a notification module configured to, in response to determining that the intelligent assets need maintenance, send a notification for maintaining the intelligent assets to the device operation production control system. 4. The system of claim 1, wherein the system is in an asset management system. 5. A method for maintaining intelligent assets, comprising:obtaining work performance data comprising workload accomplished by the intelligent assets from a device operation production control system;obtaining operation status data comprising power consumption of the intelligent assets;calculating, with a processor, a first ratio between the workload accomplished by the intelligent assets and the power consumption, and calculating a loss degree of the intelligent assets according to said first ratio and a second ratio between a workload accomplished by the intelligent assets and the power consumption at an initial time, wherein an initial time comprises when the intelligent assets are just put into operation; anddetermining whether the intelligent assets need maintenance according to the calculated loss degree of the intelligent assets. 6. The method of claim 5, wherein determining whether the intelligent assets need maintenance according to the calculated loss degree comprises:when the loss degree of the intelligent assets is determined to be greater than a predetermined threshold, determining that the intelligent assets need maintenance. 7. The method of claim 5, further comprising:when determining that the intelligent assets need maintenance, sending a notification for maintaining the intelligent assets to the device operation production control system. 8. The method of claim 5, wherein the method is executed by an asset management system. 9. A computer program product for maintaining intelligent assets, the computer program product comprising a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:computer readable program code configured to obtain work performance data comprising workload accomplished by the intelligent assets from a device operation production control system;computer readable program code configured to obtain operation status data comprising power consumption of the intelligent assets;computer readable program code configured to calculate a first ratio between the workload accomplished by the intelligent assets and the power consumption, and to calculate a loss degree of the intelligent assets according to said first ratio and a second ratio between a workload accomplished by the intelligent assets and the power consumption at an initial time, wherein an initial time comprises when the intelligent assets are just put into operation; andcomputer readable program code configured to determine whether the intelligent assets need maintenance according to the calculated loss degree of the intelligent assets. 10. The computer program product of claim 9, further comprising computer readable program code configured to determine whether the intelligent assets need maintenance according to the calculated loss degree comprises:when the loss degree of the intelligent assets is determined to be greater than a predetermined threshold, computer readable program code configured to determine that the intelligent assets need maintenance. 11. The computer program product of claim 9, when determined that the intelligent assets need maintenance, computer readable program code configured to send a notification for maintaining the intelligent assets to the device operation production control system.
