Abstract

The disclosure relates to a method and system for intelligent visualization in the monitoring of process and/or system data used in technical processes and in the operation of technical systems. The behavior of signals in the past is analyzed and used for a future optimized visualization. Continuously running online algorithms support the system operator by detecting and correspondingly highlighting deviations from the historically observed signal patterns.

First claim

What is claimed is:

1. A method for the intelligent visualization in a monitoring of process and/or system data of a technical process or in an operation of a technical system, wherein a past behavior of a process and/or system data is analyzed and used for an optimized visualization, and wherein deviations from historically observed signal patterns are detected and correspondingly highlighted by continuously running online algorithms, the method comprising:
identifying silent signals by finding those of the process and/or system data that have not changed for a predefined past period of time;
combining a plurality of these silent signals in a single view or representation form that does not include any signals not identified as silent signals;
performing a variance monitoring of the process and/or system data corresponding to the silent signals;
determining an estimated variance of each of the silent signals of the process and/or system data;
in an event that the estimated variance of one of the silent signals exceeds a preconfigured threshold value, setting the corresponding silent signal from the plurality of combined silent signals “active”; and
displaying the corresponding “active” silent signal in a highlighted manner and/or reporting it.

2. The method as claimed in claim 1 , wherein the process and/or system data comprises mass data.

3. The method as claimed in claim 2 , wherein the mass data is a plurality of process and/or operating data.

4. The method as claimed in claim 1 , comprising:
defining a similarity metric;
evaluating the similarity metric for all process and/or system data with an algorithm; and
displaying as combined in a single view, the process and/or system data that has been determined to be sufficiently similar in the past.

5. The method as claimed in claim 4 , comprising:
regularly monitoring and evaluating online by an evaluation module, the similarity metric; and
automatically providing and/or displaying in a separate representation, signals that no longer meet a similarity criteria.

6. The method as claimed in claim 1 , comprising:
analyzing online with respect to dominant fluctuations by an analysis module unfiltered raw signals of the process and/or system data.

7. The method as claimed in claim 6 , comprising:
subtracting detected dominant fluctuations from the signal; and
separately displaying the detected dominant fluctuations.

8. The method as claimed in claim 1 , wherein the process and/or system data comprises:
measured values, process variables, and/or state messages of the technical system or the technical process.

9. A system for the intelligent visualization in a monitoring of process and/or system data, the system comprising:
a technical process or technical system;
a processor configured to:
analyze a past behavior of a process and/or system data and used for an optimized visualization, and wherein deviations from historically observed signal patterns are detected and correspondingly highlighted by continuously running online algorithms;
identify silent signals by finding those of the process and/or system data that have not changed for a predefined past period of time;
combine a plurality of these silent signals in a single view or representation form that does not include any signals not identified as silent signals;
perform a variance monitoring of the process and/or system data corresponding to the silent signals;
determine an estimated variance of each of the silent signals of the process and/or system data; and
in an event that the estimated variance of one of the silent signals exceeds a preconfigured threshold value, set the corresponding silent signal from the plurality of combined silent signals “active”; and

a display configured show the corresponding “active” silent signal in a highlighted manner.

10. The system as claimed in claim 9 , wherein the process and/or system data comprises mass data.

11. The system as claimed in claim 10 , wherein the mass data is a plurality of process and/or operating data.

12. The system as claimed in claim 9 , comprising:
defining a similarity metric;
evaluating the similarity metric for all process and/or system data with an algorithm; and
displaying as combined in a single view, the process and/or system data that has been determined to be sufficiently similar in the past.

13. The system as claimed in claim 12 , comprising:
regularly monitoring and evaluating online by an evaluation module, the similarity metric; and
wherein signals that no longer meet a similarity criteria are automatically provided and/or displayed in a separate representation.

14. The system as claimed in claim 9 , comprising:
analyzing online with respect to dominant fluctuations by an analysis module unfiltered raw signals of the process and/or system data.

15. The system as claimed in claim 14 , wherein detected dominant fluctuations are subtracted from the signal and displayed separately.

16. The system as claimed in claim 9 , wherein the process and/or system data comprises:
measured values, process variables, and/or state messages of the technical system or the technical process.

17. A method for the intelligent visualization in a monitoring of process and/or system data of a technical process or in an operation of a technical system, the method comprising:
analyzing a past behavior of a process and/or system data and used for an optimized visualization, and wherein deviations from historically observed signal patterns are detected and correspondingly highlighted by continuously running online algorithms;
identifying silent signals by finding those of the process and/or system data that have not changed for a predefined past period of time;
combining a plurality of these silent signals in a single view or representation form that does not include any signals not identified as silent signals;
performing a variance monitoring of the process and/or system data corresponding to the silent signals;
determining an estimated variance of each of the silent signals of the process and/or system data;
in an event that the estimated variance of one of the silent signals exceeds a preconfigured threshold value, setting the corresponding silent signal from the plurality of combined silent signals “active”; and
displaying the corresponding “active” silent signal in a highlighted manner.
