Abstract

In a method according to the invention or a corresponding device data generated in a technical system is captured and provided with an information element. A sequential data processing of the data takes place by means of at least two data processing modules in preferably random order, whereby the status of the information element is changed.

Claims

1-18. -18. (canceled)

19. A method for multistage data processing in a power generating station, comprising:

acquiring power plant data in the electric power generating station;

selecting a portion of the acquired data based upon measured values obtained by a sensor;

assigning the selected data to an information element for subsequent processing;

identifying a processing status of the selected data;

sequentially processing the selected data by a plurality of data processing modules; and

changing the status of the information element by the data processing modules.

20. The method according to claim 19, wherein the sequence of the data processing by the plurality of data processing modules is random.

21. The method according to claim 19, wherein the acquisition of the data is in a clock-controlled manner.

22. The method according to claim 19, wherein the captured data is subdivided into a plurality of data packets.

23. The method according to claim 22, wherein a data packet is assigned an information element.

24. The method according to claim 19, wherein the captured data is stored in a memory device or a database.

25. The method according claim 19, wherein the status of the information element represents a processing status of the captured data.

26. The method according to claim 25, wherein the processing status comprises information regarding whether the captured data has already been processed by a specific data processing module and whether this processing was successful.

27. The method according to claim 25, wherein the processing status comprises information regarding whether the captured data has already been processed by a specific data processing module or whether this processing was successful.

28. The method according to claim 19, wherein the data processing performed by the data processing modules is controlled by a control device.

29. The method according to claim 28, wherein a portion of the data processing modules are assigned to a distinct control device.

30. The method according to claim 19, wherein the data processing modules are clock-controlled.

31. A device for multistage data processing in a power generating station, comprising:

an apparatus for measured value acquisition such that a portion of the data acquired in the power generating station is captured while the power generating station is in operation;

an information element assigned to the captured data, wherein the processing status of the data can be identified by the element; and

a plurality of data processing modules for sequential processing of the captured data,

wherein

the status of the information element can be modified by the data processing modules.

32. The device according to claim 31, further comprising a clock generator for clock-controlled acquisition of the data.

33. The device according to claim 31, wherein the captured data can be subdivided into a number of data packets by a processing unit.

34. The device according to claim 33, wherein a data packet is assigned a (distinct) information element.

35. The device according to claim 31, wherein the captured data is stored in a memory.

36. The device according to claim 31, wherein the data processing performed by the data processing modules is controlled by a control unit.
