Title: Indication Display System

Description:
TECHNICAL FIELD 
     This disclosure relates generally to an indication display system for a machine, and, more particularly, to an indication display system having an operator interface mounted in an operator cab of a machine. 
     BACKGROUND 
     In a variety of engine-powered machines, monitoring devices are employed to detect the presence of various undesirable operating conditions, such as the overheating of the engine, low oil pressure, low fuel and the like. Indicators are provided to warn the operator of such conditions. 
     The degree of importance of the various monitored conditions may vary. For example, the air filter for the engine or the filter for the hydraulic fluid may gradually clog during operation of the vehicle. Generally, there is no need to remedy the situation until the end of the day when the machine returns for normal servicing and maintenance. A low fuel condition requires more immediate attention from the operator. A loss of engine oil pressure or a loss of hydraulic fluid represent conditions which require immediate operator attention to prevent damaging the machine. 
     Prior monitoring systems have detected the presence of undesirable conditions and then signaled the operator by means of dial indicators, indicator lamps, or audible means. The efficiency of these systems may depend upon the operator&#39;s careful attention to all of the various indicators and upon his judgment as to which may call for immediate correction. As the complexity of a machine increases, the number of monitored parameters generally increases. Therefore, the operator is required to direct more attention to the increasing number of indicators and less attention to operating the machine. 
     U.S. Pat. No. 4,442,424 is entitled, “Method and System for Displaying Vehicle Operating Parameters in a Variable Format.” The &#39;424 patent is directed to a display system wherein a plurality of engine operating parameters and useful information items are monitored by respective sensors. A control unit receives signals from the sensors to display the monitored items in a variable format on a single viewing screen in accordance with the conditions of the monitored items. When an abnormal condition of one of the monitored items is detected by the control unit, the display format of the monitored item with an abnormal condition is enlarged to give a warning indication. A pushbutton is provided for each of the monitored items to generate a display command signal in response to a manual command to provide a display of a desired item in an enlarged format. However, as the number of discrete warning messages increases, so does demand for space on the display screen and attention by the operator. These and other shortcomings are addressed by the present disclosure. 
     SUMMARY 
     In one aspect, the disclosure describes an indication display system for a machine, the system including an operator interface including a display screen, the display screen having at least one fixed indicator light and a machine performance information display section configured to display information indicating at least one machine parameter and a message display section configured to selectively display at least one pop-up message, wherein the fixed indicator light is disposed adjacent a portion of the machine performance information display section, a data storage device, the data storage device storing at least message data, and a controller operably arranged with the data storage device and the operator interface, the controller, in response to receiving a signal indicative of a first machine condition, configured to illuminate the fixed indicator light and to assemble from the message data in the data storage device a first pop-up message describing the first machine condition and to provide the first pop-up message to the operator interface for display in the message display section of the display screen simultaneously with illumination of the fixed indicator light.

     For example, in one aspect, the text string  650  includes a suffix, “−3,” which indicates the pop-up message  610  of  FIG. 10  includes a Warning Level 3 pop-up message. The illustrated background color  652  of the pop-up message area box  640  is red to also signify the pop-up message  610  of  FIG. 10  includes a Warning Level 3 pop-up message. 
     If multiple pop-up messages are active, a scroll arrow touch element  620  and indicia  625  shall appear indicating so. In aspects, pressing the scroll arrow touch element  620  allows the operator  140  to page through all active pop-up messages, including active pop-up messages having a lesser rank. In aspects, if the operator  140  has not pressed the scroll arrow touch element  620  for a predetermined amount of time (e.g., 5 seconds), the controller  145  may be configured to sequentially display active Warning Level 3 pop-up messages only. 
     In aspects, the Level 3 Warning pop-up message  610  may be “snoozed” for a predetermined amount of time (e.g., 5 minutes), after which it reappears if the machine condition generating the warning is still active. In aspects, at least one Level 3 Warning pop-up message is configured such that it does not have an enabled snooze feature. 
     In aspects, a priority hierarchy may include warning pop-up messages as described above and information pop-up messages, which may be used to provide non-safety critical messages to the operator. In aspects, the information pop-up message may have a high level of configurability, thereby allowing each information pop-up message to be individually-customized to provide the appropriate information. The information pop-up message may include a text string including complete words to allow for greater understanding and better translation into different languages. In aspects, an information pop-up message is superseded by an active Level 1 Warning pop-up message. 
     INDUSTRIAL APPLICABILITY 
     The Aspects of an indication display system for a machine are described herein. The industrial applicability of aspects constructed according to principles of the disclosure of an indication display system for a machine will be readily appreciated from the foregoing discussion. The described principles are applicable for use in multiple aspects of a machine, including trucks, cranes, earth moving vehicles, mining vehicles, cold planers, wheel loaders, backhoes, motor graders, track type tractors, hydraulic excavators, track type loaders, material handling equipment, farming equipment, marine vessels, aircraft, off-road vehicles, and other types of movable machines. Moreover, the principles disclosed herein may be incorporated in with other machines that are not movable including generator sets, turbines, mining equipment, and the like. 
     The disclosed systems and methods may provide a multi-functional user interface on a work machine to display information associated with the operations of the work machine. This information may include suggested corrective actions associated with detected abnormal operational conditions and/or service-triggering conditions of the machine. 
     In aspects, an indication display system for a machine includes a display screen having a dedicated information banner. The display screen is configured to maintain display of machine parameters and productivity information and simultaneously display the information banner. The information banner displays sacrificial information of lower priority when warning messages are not needed (such as operator name, temperature, time, etc.) and display critical message and/or warnings when needed. 
     When a machine condition is detected that triggers a pop-up message, the pop-up message is displayed in the information banner, and the sacrificial information is overwritten. An operator may touch the banner or button to snooze the pop-up message. The information banner again displays the sacrificial information and also displays an alert reminder symbol to indicate an active pop-up message has been removed from the display screen. The operator may touch the reminder symbol to launch a display that shows a list of warnings that have accumulated. The operator may select one of the warnings to launch another display having the details of the selected warning. 
     Referring to  FIG. 11 , steps of an aspect of a method of displaying operational information of a machine following principles of the disclosure are shown in flowchart form. In step  702 , information relating to an indication of one or more first machine conditions may be received or accessed, for example, via one or more sensors (e.g., sensors  137  ( FIG. 2 )). 
     In step  704 , in response to receiving an indication of a first machine condition, a first pop-up message may be caused to be displayed. As an example, the first pop-up message may be caused to be displayed in an information banner of a display screen of an operator interface. As another example, the first pop-up message may include data describing the first machine condition. As an illustrative example, the operator interface  135  is shown in  FIG. 12  with at least one of the graphical indicators  181  illuminated simultaneously with the first pop-up message presented via the message display section  180 . Such a configuration may be associated with a level 1 warning level. In certain aspects, the first pop-up message includes an illuminated color that matches an illuminated color of the illuminated graphical indicator  181 . As an example, an operator may acknowledge the first pop-up message by engaging (e.g., contacting) a portion of the operator interface  135  such as the message display section  180 . 
     In step  706 , machine performance information may be caused to be displayed. As an example, the machine performance information may be caused to be displayed in a machine performance information display section (e.g., machine performance information display section  175  ( FIG. 5 )) of the display screen. As another example, the machine performance information may be caused to be displayed simultaneously with displaying the first pop-up message. As a further example, the information banner may be disposed in non-overlapping relationship with the machine performance information display section of the display screen. 
     In step  708 , a first fixed indicator light may be caused to be illuminated. As an example, the first fixed indicator light may be disposed adjacent the machine performance information display section. As a further example, the first fixed indicator light may be caused to be illuminated simultaneously with displaying the first pop-up message. As an illustrative example, the operator interface  135  is shown in  FIG. 13  with at least one of the graphical indicators  181  and a first one of the indicator lights  182  illuminated simultaneously with the first pop-up message presented via the message display section  180 . Such a configuration may be associated with a level 2 warning level. In certain aspects, the first pop-up message includes an illuminated color that matches an illuminated color of the first one of the indicator lights  182  and/or the graphical indicator  181 . As an example, an operator may acknowledge the first pop-up message by engaging (e.g., contacting) a portion of the operator interface  135  such as the message display section  180 . 
     Returning to  FIG. 11 , in step  710 , information relating to an indication of one or more second machine conditions may be received or accessed, for example, via one or more sensors (e.g., sensors  137  ( FIG. 2 )). 
     In step  712 , in response to receiving an indication of a second machine condition, a second pop-up message may be caused to be displayed. As an example, the second pop-up message may be caused to be displayed in the information banner (e.g., message display section  180  ( FIG. 5 )) of the display screen of the operator interface. As another example, the second pop-up message may include data describing the second machine condition. 
     In step  714 , a second fixed indicator light may be caused to be illuminated. As an example, the second fixed indicator light may be disposed adjacent the machine performance information display section. As a further example, the second fixed indicator light may be caused to be illuminated simultaneously with displaying the second pop-up message. As an illustrative example, the operator interface  135  is shown in  FIG. 14  with at least one of the graphical indicators  181  and a second one of the indicator lights  182  illuminated simultaneously with the second pop-up message presented via the message display section  180 . Such a configuration may be associated with a level 3 warning level. In certain aspects, the second pop-up message includes an illuminated color that matches an illuminated color of the second one of the indicator lights  182  and/or the graphical indicator  181 . As an example, an operator may acknowledge the second pop-up message by engaging (e.g., contacting) a portion of the operator interface  135  such as the message display section  180 . An audible alarm may also be generated simultaneously with the illumination of the second one of the indicator lights  182 .
