Abstract

An apparatus for alarm information determination includes: an input unit; a processing unit; and an output unit. The input unit provides the processing unit with historical process control data, the process control data including a plurality of data signals, a plurality of alarm data, and data relating to an event of interest. The processing unit determines a plurality of correlation scores for the plurality of data signals paired with the plurality of alarm data, a correlation score being determined for a data signal paired with an alarm data, a high correlation score indicating a higher degree of correlation than a low correlation score. The processing unit identifies at least one first alarm data from the plurality of alarm data, the identification including utilization of the data relating to the event of interest.

First claim

2 . The apparatus according to claim 1 , wherein identification of the at least one first data signal comprises a determination of one or more data signals of the plurality of data signals that have highest correlation scores when paired with the at least one alarm data.

3 . The apparatus according to claim 1 , wherein the processing unit is configured to determine a plurality of correlation scores for pairs of data signals of the plurality of data signals,
wherein the correlation score is determined for different pairs of data signals, wherein a high correlation score indicates a higher degree of correlation between a pair of data signals than a low correlation score, wherein the processing unit is configured to identify at least one second data signal of the plurality of data signals, the identification comprising utilization of the correlation scores for the identified at least one first data signal paired with the plurality of data signals, and wherein the output unit is configured to output the at least one second data.

4 . The apparatus according to claim 3 , wherein identification of the at least one second data signal comprises a determination of one or more data signals of the plurality of data signals that have highest correlation scores when paired with the at least one first data signal.

5 . The apparatus according to claim 4 , wherein the output unit is configured to output the one or more data signals,
wherein the input unit is configured to enable a user to select at least one data signal of the one or more data signals, and wherein the identified at least one second data signal is the at least one data signal selected by the user.

6 . The apparatus according to claim 3 , wherein the processing unit is configured to identify at least one second alarm data from the plurality of alarm data, the identification comprising utilization of the correlation scores for the identified at least one second data signal paired with the plurality of alarm data, and
wherein the output unit is configured to output the at least one second alarm data.

7 . The apparatus according to claim 6 , wherein identification of the at least one second alarm data comprises a determination of one or more alarm data of the plurality of alarm data that have highest correlation scores when paired with the identified at least one second data signal.

8 . The apparatus according to claim 7 , wherein the output unit is configured to output the one or more alarm data,
wherein the input unit is configured to enable a user to select at least one alarm data of the one or more alarm data, and wherein the identified at least one second alarm data is the at least one alarm data selected by the user.

9 . The apparatus according to claim 1 , wherein the data relating to the event of interest comprises a user input query term, and
wherein the processing unit is configured to utilize the user input query term to identify the at least one first alarm data.

10 . The apparatus according to claim 9 , wherein the plurality of alarm data are stored in a database, and
wherein the user input query term is utilized to identify the at least one first alarm data.

11 . A method for alarm information determination, comprising:
a) providing a processing unit with historical process control data from an input unit, the process control data comprising a plurality of data signals, a plurality of alarm data, and data relating to an event of interest; b) determining by the processing unit a plurality of correlation scores for the plurality of data signals paired with the plurality of alarm data, a correlation score being determined for a data signal paired with an alarm data, a high correlation score indicating a higher degree of correlation than a low correlation score; c) identifying by the processing unit at least one first alarm data from the plurality of alarm data, the identification comprising utilization of the data relating to the event of interest; d) identifying at least one first data signal from the plurality of data signals, the identification comprising the processing unit utilizing the correlation scores for the identified at least first one alarm data paired with the plurality of data signals; and h) outputting by an output unit the at least one first data signal.

12 . The method according to claim 11 , further comprising:
e) determining by the processing a plurality of correlation scores for pairs of data signals of the plurality of data signals, a correlation score being determined for different pairs of data signals, a high correlation score indicating a higher degree of correlation between a pair of data signals than a low correlation score; and f) identifying at least one second data signal of the plurality of data signals, the identification comprising the processing unit utilizing the correlation scores for the identified at least one first data signal paired with the plurality of data signals, wherein step h) comprises outputting the at least one second data.

13 . The method according claim 11 , further comprising:
g) identifying at least one second alarm data from the plurality of alarm data, the identification comprising the processing utilizing the correlation scores for the identified at least one second data signal paired with the plurality of alarm data, wherein step h) comprises outputting the at least one second alarm data.

14 . The method according to claim 11 , wherein in step a) the data relating to the event of interest comprises a user input query term, and
wherein step c) comprises utilizing the user input query term to identify the at least one first alarm data.

15 . A computer program element for controlling the apparatus according to claim 1 , which when executed by a processor is configured to carry a method for alarm information determination, the method comprising:
