Abstract

One embodiment of the application provides a system for visualizing trend data of an industrial performance (e.g., utility consumption) of a power plant. The system includes a macro trend view generator, navigator, a pointer position calculator, and a micro trend view controller. The macro trend view generator is configured to generate a macro trend view of a sensed parameter in a display. The navigator is configured to navigate a pointer for locating an area in the macro trend view. The pointer position calculator is configured to calculate a position of the pointer in the macro trend view. The micro trend view controller is configured to generate a micro trend view associated with the located area in the display, as a function of the calculated position of the pointer in the macro trend view.

Claims

1. A system for visualizing trend data of a sensed parameter, comprising:

a macro trend view generator configured to generate a macro trend view of sensed parameter in a display;

a navigator configured to navigate a pointer for locating an area in the macro trend view;

a pointer position calculator configured to calculate a position of the pointer in the macro trend view; and

a micro trend view controller configured to generate a micro trend view associated with the located area in the display, as a function of the calculated position of the pointer in the macro trend view.

2. The system of claim 1, further comprising a user operation detector configured to detect a user operation to the macro trend view.

3. The system of claim 1, wherein the pointer is in a rectangular shape, and positions of a pair of parallel sides of the rectangular pointer in the macro trend view determine start and end times of the micro trend view.

4. The system of claim 1, further comprising a macro trend view monitoring parameter receiver configured to receive macro trend view monitoring parameters from an input device.

5. The system of claim 4, wherein the macro trend view monitoring parameters includes start time, end time, and time interval of the macro trend view.

6. The system of claim 1, further comprising a micro trend view monitoring parameter adjuster configured to adjust a micro trend view monitoring parameter.

7. The system of claim 1, further comprising a data access module configured to retrieve data from a database for generating the macro trend view.

8. The system of claim 7, further comprising a cache configured to store the retrieved data from the database for generating the micro trend view.

9. A method for visualizing trend data of a sensed parameter, comprising:

receiving a request to display a macro trend view in a display, the request includes macro trend view monitoring parameters;

retrieving macro trend data from a database as a function of the macro trend view monitoring parameters;

converting the retrieved macro trend data into the macro trend view to display in the display;

detecting a user operation of a navigation pointer on the macro trend view;

if the user operation detected, calculating a position of the navigation pointer in the macro trend view;

retrieving micro trend data as a function of the calculated position of the navigation pointer; and

converting the retrieved micro trend view data into the micro trend view to display in the display.

10. The method of claim 9, further comprising:

after retrieving the macro trend data, storing the retrieved macro trend data in a cache to be future used for generating the micro trend view.

11. The method of claim 10, wherein the retrieving micro trend data includes retrieving the micro trend data from the cache as a function of the calculated position of the navigation pointer.

12. A method for visualizing trend data of utility consumption, comprising:

generating a macro trend view from macro trend data;

detecting a user operation of a navigation pointer on the macro trend view;

calculating a position of the navigation pointer; and

generating a micro trend view from micro trend data as a function of the calculated position of the navigation pointer.

13. The method of claim 12, further comprising storing the macro trend data in a cache to be future used for generating the micro trend view.

14. The method of claim 13, wherein the generating a micro trend view from micro trend data includes retrieving the micro trend data from the cache as a function of the calculated position of the navigation pointer.

15. A machine-readable medium comprising instructions, which when implemented by one or more processors, perform the following operations:

receiving a request to display a macro trend view in a display, the request includes macro trend view monitoring parameters;

retrieving macro trend data from a database as a function of the macro trend view monitoring parameters;

converting the retrieved macro trend data into the macro trend view to display in the display;

detecting a user operation of a navigation pointer on the macro trend view;

if the user operation detected, calculating a position of the navigation pointer in the macro trend view;

retrieving micro trend data as a function of the calculated position of the navigation pointer; and

converting the retrieved micro trend view data into the micro trend view to display in the display.

16. The computer-readable medium of claim 15, further comprising instructions, which when implemented by one or more processors, perform the following operation:

after retrieving the macro trend data, storing the retrieved macro trend data in a cache to be future used for generating the micro trend view.

17. The computer-readable medium of claim 16, wherein the retrieving micro trend data includes retrieving the micro trend data from the cache as a function of the calculated position of the navigation pointer.

18. A graphical user interface (GUI) of a trend data view of a sensed parameter, comprising:

a first region displaying a macro trend view associated with utility consumption;

a second region displaying a navigation pointer to locate an area within the first region; and

a third region displaying a micro trend view of the located area, the micro trend view is a magnified view of the located area from the macro trend view.

19. The GUI of claim 18, further the navigation pointer is a text cursor.

20. The GUI of claim 18, further the navigation pointer is a rectangular mouse pointer.
