Abstract

A diagnostic application or system for a power machine is disclosed. The diagnostic application or system generates a diagnostic menu to select one or more diagnostic items for diagnostic monitoring. Sensor data for the selected items is retrieved from one or more sensors and displayed on an electronic display device. In the embodiments described, the application or system includes a graphical user interface component configured to generate a display options menu including one or more user selectable display formats or options.

Claims

1. A diagnostic system comprising:

a diagnostic component configured to retrieve sensor data for one or more selected diagnostic items; and

a diagnostic menu generator configured to generate a diagnostic menu including one or more user selectable diagnostic items on an electronic display device and a graphical display generator configured to generate a graph of the sensor data along a time axis for the one or more user selected diagnostic items.

2. The diagnostic system of claim 1 including a display options menu generator configured to generate a display options menu including a plurality of user selectable display formats for the sensor data.

3. The diagnostic system of claim 2 wherein the plurality of user selectable display formats include a graphical display format and a list view display format.

4. The diagnostic system of claim 2 wherein the plurality of user selectable display formats includes a composite graphical display format including one or more graphs on a composite display and a segregated graphical display format including one or more segregated graph segments.

5. The diagnostic system of claim 2 wherein the display options menu generator generates a plurality of input fields to select display parameters for the one or more user selectable diagnostic items.

6. The diagnostic system of claim 5 wherein the plurality of user selectable display parameters includes a plurality of color selections.

7. The diagnostic system of claim 1 wherein the diagnostic menu generator is implemented through a graphical user interface component of an application program.

8. The diagnostic system of claim 7 wherein the graphical user interface component is configured to generate start or stop function buttons to activate or stop sensor data retrieval.

9. The diagnostic system of claim 7 wherein the graphical user interface component is configured to generate a custom template to configure the diagnostic component to retrieve sensor data for a particular machine or sensors.

10. A diagnostic application implementable on a computer readable medium comprising:

a diagnostic component configured to receive sensor data from a power machine for one or more user selected diagnostic items; and

a diagnostic menu generator configured to generate a diagnostic menu including a plurality of user selectable diagnostic items on an electronic display device and a display options menu generator configured to generate a display options menu on the electronic display device including a plurality of user selectable display formats to display the sensor data for the one or more user selected diagnostic items.

11. The diagnostic application of claim 10 wherein the display options menu includes a composite graph display format and a segregated graph display format including a plurality of segregated graph segments for the one or more selected diagnostic items.

12. The diagnostic application of claim 10 wherein the display options menu includes a graphical display format and a list view display format which displays an alphanumeric list of sensor readings.

13. The diagnostic application of claim 10 and further comprising a graphical display generator configured to generate a graphical display for the sensor data in response to selection of a graphical display format from the display options menu.

14. The diagnostic application of claim 13 wherein the graphical display generator is configured to generate a display legend including one or more item descriptions for the one or more user selected diagnostic items and one or more legend symbols to associate sensor data to the one or more item descriptions.

15. The diagnostic application of claim 10 and further comprising a display segment generated through a graphical user interface component to display sensor data for the one or more user selected diagnostic items.

16. The diagnostic application of claim 15 wherein the graphical user interface component generates an alternate data display function invokable through the graphical user interface component to display an alternate display item.

17. The diagnostic application of claim 16 wherein the alternate display function displays one of a data value for a select point on a graphical display, an acceptable minimum sensor value and acceptable maximum sensor value.

18. A computer implemented method comprising the steps of:

receiving a selection of one or more diagnostic items from a diagnostic menu having one or more user selectable diagnostic items;

retrieving sensor data from one or more sensors coupled to a power machine for the one or more selected diagnostic items; and

displaying sensor data for the one or more diagnostic items using one or more display formats selected from a display options menu including a plurality of user selectable display formats.

19. The method of claim 18 and further comprising the step of:

graphically displaying the sensor data for the one or more diagnostic items using one or more display colors selected from the display options menu.

20. The method of claim 18 and further comprising the step of:

graphically displaying the sensor data using one of a composite graphical display format or segregated graphical display format for the one or more selected diagnostic items.
