Abstract

In situations where first equipment of a first technical installation could hitherto not be monitored based on condition data of the first equipment from the first equipment alone, it is proposed that a first sensor measures first condition data of the first equipment and that art additional sensor measures additional condition data of an additional equipment of an additional technical installation. The first condition data and the additional condition data are transmitted to a sorting unit and processed by the sorting unit into a ranking list. A corresponding sorting unit and a system as well as a corresponding computer program and a computer program product are also disclosed.

Claims

1-12. -12. (canceled)

13. A method for monitoring a first item of equipment of a first technical installation, comprising:

with a first sensor, detecting first condition data for the first item of equipment,

with an additional sensor, detecting additional condition data for an additional item of equipment of an additional technical installation,

transmitting the first condition data and the additional condition data to a sorting unit, and

with the sorting unit, processing the first condition data and the additional condition data into a ranking list.

14. The method of claim 13, wherein the ranking list is created by comparing the first condition data with the additional condition data.

15. The method of claim 13, wherein at least one of the ranking list and a rank of the first condition data in the ranking list is transmitted to a data processing unit of the first item of equipment or of the first technical installation, or both.

16. The method of claim 13, further comprising creating a report when the first condition data have a less favorable rank than the additional condition data in the ranking list.

17. The method of claim 13, further comprising compressing at least one of the first condition data and the additional condition data prior to transmission to the sorting unit.

18. The method of claim 13, further comprising

storing at least one item selected from the first condition data, the first condition data together with the additional condition data, and the ranking list in a storage unit of the sorting unit,

transmitting first repair data relating to a repair of the first item of equipment or of the first technical installation, or both, and transmitting additional repair data relating to a repair of the additional equipment or of the additional technical installation, or both to the sorting unit and storing the first repair data and the additional repair data in the storage unit of the sorting unit,

correlating at least one item selected from the first condition data, the first condition data together with the additional condition data and a rank of the first and additional condition data with the respective first and additional repair data, and

determining based on the correlation whether at least one of the first item of equipment and the first technical installation requires a repair.

19. The method of claim 18, further comprising

identifying based on the ranking list and the first and additional repair data stored in the storage unit of the sorting unit a condition of at least one of the first item of equipment and of the first technical installation, or

determining for the first condition data a limit value that indicates whether a repair of at least one of the first item of equipment and the first technical installation is necessary.

20. The method of claim 18, further comprising

determining based on the correlation when a repair of at least one of the first item of equipment and the first technical installation is required.

21. A sorting unit for monitoring a first item of equipment of a first technical installation, comprising

an interface receiving first condition data for the first item of equipment and additional condition data for an additional item of equipment of an additional technical installation, and

a computing unit configured to process the first condition data and the additional condition data into a ranking list.

22. A system for monitoring a first item of equipment of a first technical installation, comprising

a first sensor for detecting first condition data for the first item of equipment,

an additional sensor for detecting additional condition data of an additional item of equipment of an additional technical installation, and

a sorting unit comprising

an interface receiving the first condition data for the first item of equipment and the additional condition data for an additional item of equipment of the additional technical installation, and

a computing unit configured to process the first condition data and the additional condition data into a ranking list.

23. A computer program comprising program code embodied on a non-transitory computer-readable medium, wherein the computer program, when loaded into a memory of a sorting unit and executed by the sorting unit, causes the sorting unit to:

receive first condition data of a first item of equipment of a first technical installation measured by a first sensor,

receive additional condition data of an additional item of equipment of an additional technical installation measured by an additional sensor, and

process the first condition data and the additional condition data into a ranking list.

24. A computer program product embodied on a non-transitory computer-readable medium and comprising computer program code, wherein the computer program code, when loaded into a memory of a sorting unit and executed by the sorting unit, causes the sorting unit to:

receive first condition data of a first item of equipment of a first technical installation measured by a first sensor,

receive additional condition data of an additional item of equipment of an additional technical installation measured by an additional sensor, and

process the first condition data and the additional condition data into a ranking list.
