Abstract

The system for displaying prioritized live thumbnail of process graphic views includes at least one real time data source 406 for providing live data information and at least one engineering information data source 409. Graphic File Monitor 401 is configured for monitoring change in graphic files repository 405 and Tag Extractor 407 is configured for extracting tags from graphic file for monitoring based on predefined rules. The system also includes Tag Monitor 402 for monitoring alarm status and/or data status changes of monitored tags and reading tag importance and alarm priority for monitored tags and View Ranker 408 for prioritizing the graphic views by ranking. Prioritized Thumbnail Presenter System 403 is used for displaying top most prioritized graphics that requires attention. Display system 404 is provided for displaying the prioritized live thumbnails and enlarged view of the process graphic views and update data into graphic objects displayed in graphic views.

Claims

1. An automation system for management and process control in a plant, comprising:

a field controller providing the process control using function blocks identified by tags;

a real time data source providing live data information;

a graphic files repository storing graphic files that are configured for monitoring and controlling operations in the plant;

an engineering information data source providing engineering information including tag importance levels and alarm priority levels about process tags used by the field controller;

a server computer configured with;

a graphic file monitor that monitors addition, deletion, or change in the graphics files stored in the graphic files repository;

a tag extractor that extracts tags identifying function blocks from the graphic files from the graphics files repository based on predefined rules for monitoring;

a tag monitor that monitors alarm status and data status changes of the tags extracted by the tag extractor for monitoring and reading an importance of the monitored tags and an alarm priority for the monitored tags; and

a view ranker that prioritizes graphic views used in the graphic files for the monitored tags by ranking each of the graphic views based on a total score determined from values for the tags related to each graphic view mapped in a graphic ranking table mapping different tag importance levels with different alarm priority levels corresponding to each of the tags related to each graphic view; and

a Human-Machine Interface (HMI) machine generating and displaying graphics pages as an interface to control and monitor operations in the plant, the HMI machine communicating with the field controller and the server computer, and the HMI machine being configured with;

a prioritized thumbnail presenter system that automatically displays thumbnails of the graphic views prioritized by the view ranker, with the thumbnail of the highest scoring graphic view highlighted with a border to draw attention of the operator; and

a display system displaying pre-configured views of the thumbnails of the graphic views prioritized by the view ranker and updating the pre-configured views of the thumbnails of the graphic views prioritized by the view ranker with real time data.

2. The system as claimed in claim 1, wherein the real time data source (406) is one of a system controller or a simulator or a database.

3. The system as claimed in claim 1, wherein the engineering information data source is either a file or a database.

4. The system as claimed in claim 1, wherein the tag monitor maintains an association map between the monitored tags and the graphic view.

5. The system as claimed in claim 1, wherein the view ranker in the server computer further prioritizes the graphics views by ranking using alarm status and customized rules.

6. The system as claimed in claim 1, wherein the prioritized graphic thumbnail presenter system periodically queries the tag monitor and the view ranker for the prioritized graphic views to be displayed.

7. The system as claimed in claim 1, wherein the prioritized graphic thumbnail presenter system subscribes for notification of change in ranking for the prioritized graphic views from the tag monitor and the view ranker.

8. The system as claimed in claim 1, wherein the HMI machine provides a snapshot image of one of the graphic views selected for zoom from the displayed views of the thumbnails of the graphic views prioritized by the view ranker.

9. The system as claimed in claim 1, wherein the displayed views of the thumbnails of the graphic views prioritized by the view ranker are displayed either in miniature live thumbnail format or in full view format.

10. A method of management and process control in a plant including a field controller providing process control using function blocks identified by tags, a server computer, and a Human-Machine Interface (HMI) machine communicating with each other, said method comprising the steps of:

monitoring, by the server computer, addition, deletion or change in at least one of a plurality of graphic files stored in a graphic files repository;

extracting, by the server computer, monitored tags identifying function blocks from the graphic files from the graphic files repository based on predefined rules for monitoring;

monitoring, by the server computer, at least one real time data source for alarm status and data status changes relating to the monitored tags;

reading, by the server computer, tag importance information and alarm priority information for the monitored tags from engineering information data source

prioritizing, by the server computer, graphic views used in the graphic files for the monitored tags by ranking each of the graphic views based on a total score determined from values for the tags related to each graphic view mapped in a graphic ranking table mapping different tag importance levels with different alarm priority levels corresponding to each of the tags related to each graphic views;

automatically identifying and displaying, by the HMI machine, pre-configured views of prioritized live thumbnails of the prioritized graphic views;

updating the pre-configured views of the thumbnails of the prioritized graphic views with real time data.

11. The method as claimed in claim 10, wherein the extracting of the monitored tags is based on built-in rules and customized rules.

12. The method as claimed in claim 10, wherein the graphic views are displayed either in miniature live thumbnail format or in full view format.

13. The method as claimed in claim 10, wherein an enlarged view is generated for one of the graphic views having a mouse positioned over the one of the graphic views.

14. The method as claimed in claim 10, wherein the ranking of one of the prioritized graphic views will be automatically adjusted by removing the one of the prioritized graphic views or demoting the ranking of the one of the prioritized graphic views to lower priority.

15. A non-transitory computer readable medium including operations stored thereon that when processed by at least one processor cause a system to perform the steps of:

monitoring addition, deletion or change in at least one of a plurality of graphic files stored in a graphic files repository;

extracting monitored tags identifying function blocks of a field controller from the graphic files from the graphic files repository based on predefined rules for monitoring;

monitoring at least one real time data source for alarm status and data status changes relating to the monitored tags;

reading importance information and alarm priority information for the monitored tag from engineering information data source;

ranking each of the graphic views used in the graphic files for the monitored tags based on a total score determined from values for the tags related to each graphic view mapped in a graphic ranking table mapping different tag importance levels with different alarm priority levels corresponding to each of the tags related to each graphic view;

automatically identifying and displaying pre-configured views of prioritized thumbnails of the prioritized graphic views; and

periodically updating the pre-configured views of the thumbnails of the prioritized graphic views with real time data.
