Abstract

The invention relates to method and equipment for monitoring the operation of an industrial process. The industrial process is used as a basis for compiling a document comprising a group of cause-effect relationships dependent on the industrial process. From the industrial process is collected status data of the process. A document server compares the process status data with the data provided by the group of cause-effect relationships and produces a plain-language account of the status of the industrial process.

Claims

1. A method for monitoring the operation of an industrial process, the method comprising the steps of:

collecting process status data relating to the process;

creating a document comprising a group of cause-effect relationships related to the industrial process, wherein data in the group of cause-effect relationships is subjected to preconditions based on the process status data, and wherein the process status data comprises a plurality of data, each of which contains a precondition for a particular data in the group of cause-effect relationships;

searching the group of cause-effect relationships in phases for outputs defined as true; and

producing a plain-language account of the process status on the basis of the outputs, where the plain-language account includes a statement of an effect along with a statement describing the cause of the effect.

2. A method according to claim 1, wherein said producing step produces a dynamic document containing a plain language account of the process status.

3. A method according to claim 2, wherein said producing step produces a dynamic document that changes as the process status changes.

4. A method according to claim 2, wherein said producing step updates the dynamic document when a user points to an object.

5. A method according to claim 2, wherein said producing step updates the dynamic document at regular intervals.

6. A method according to claim 2, wherein said producing step produces the dynamic document using hypertext technology.

7. A method according to claim 1, wherein said producing step produces a plain-language account of the process status that is viewable using a web browser.

8. A method according to claim 1, wherein said searching and producing steps are performed by a web server.

9. An equipment for monitoring the operation of an industrial process comprising:

means for collecting status data related to the industrial process;

storage unit for storing a group of cause-effect relationships data related to the industrial process, wherein data in the group of cause-effect relationships is subjected to preconditions based on the status data, and wherein the process status data comprises a plurality of data, each of which contains a precondition for a particular data in the group of cause-effect relationships; and

a document server for combining the process status data and the data in the group of cause-effect relationships, wherein said document server searches the group of cause-effect relationships in phases for outputs defined as true to produce a plain-language account of the process status, where the plain-language account includes a statement of an effect along with a statement describing the cause of the effect.

10. An equipment according to claim 9, wherein said document server is capable of producing a dynamic document.

11. An equipment according to claim 9, wherein said document server is capable of producing a dynamic document, wherein the dynamic document is arranged to change as the process status data changes.

12. An equipment according to claim 9, wherein said document server is capable of producing a dynamic document, wherein the dynamic document is arranged to be updated as a user points to an object.

13. An equipment according to claim 9, wherein said document server is capable of producing a dynamic document, wherein the dynamic document is arranged to be updated at regular intervals.

14. An equipment according to claim 9, wherein said document server is capable of producing a dynamic document, wherein the dynamic document is produced using hypertext technology.

15. An equipment according to claim 9 further comprising a web browser for viewing the account process status.

16. An equipment according to claim 9, wherein said document server is a web server.
