Abstract

Example methods and systems to indicate the status of door operations are disclosed. An example door system includes a door panel having a leading edge to be moved in a travel direction between an open position and a closed position relative to the doorframe. The door panel to block the passageway when the leading edge is at the closed position. The door panel to unblock the passageway when the leading edge is at the open position. The example door system also includes a series of lights distributed along the travel direction proximate the doorframe. The example door system further includes a controller to switch the lights between a first state and a second state to provide a visual effect of movement corresponding to the operating status of the door system.

Claims

1. A door system for a passageway, the door system comprising:

a door panel movable between an open position and a closed position, the door panel including a sheet extending continuously across a full height of the passageway when in the closed position;

a display positionable adjacent the passageway to provide selectively different icons immediately identifiable by a person, a size of at least one of the different icons substantially filling the display, the different icons indicative of different operational states of the door system or an impending change in a corresponding operational state of the door system, a first icon to indicate a first impending change corresponding to movement of the door panel after a time period, the first icon corresponding to a timer indicating a countdown associated with the time period; and

a controller to control operation of the door panel and the display.

2. The door system of claim 1, wherein at least one of the different icons is animated.

3. The door system of claim 1, wherein a second icon includes an arrow to indicate the door panel is at least one of closing, about to close, opening, or about to open.

4. The door system of claim 1, wherein a first one of the different operational states corresponds to when the door panel is opening and the door system is waiting for further input.

5. The door system of claim 1, wherein a second icon is to preannounce an opening of the door panel and a third icon is to preannounce a closing of the door panel, the third icon different than the second icon.

6. The door system of claim 1, wherein a first one of the different operational states corresponds to when an interlock is disabled.

7. The door system of claim 1, wherein a second icon serves as a warning of cross traffic.

8. The door system of claim 1, wherein a second icon indicates when the door system has faulted.

9. The door system of claim 1, wherein a second icon indicates a maintenance alert.

16. The door system of claim 1, further including a series of lights to be distributed adjacent the passageway along a travel direction of the door panel, the series of lights to provide a visual indication of a status of the door system separate from the display.

17. The door system of claim 1, wherein the controller includes a user interface separate from the display, the user interface to provide at least one of a visual indication of a status of the door system or an actuator to enable operation of the door system, the display to be spaced apart from an enclosure of the controller.

10. A door system comprising:

a door panel movable between a closed position and an open position to respectively block and unblock a passageway, the door panel including a sheet extending continuously across a full height of the passageway when in the closed position;

a controller to control operation of the door panel; and

a matrix display positionable adjacent the passageway in communication with the controller, the display to provide a symbol viewable by a person facing the display, the symbol indicative of an operational state of the door system, the controller to cause the display to change the symbol based on at least one of a change in the operational state of the door system or an impending change in the operational state of the door system, the impending change in the operational state corresponding to movement of the door panel after a time period, the symbol corresponding to a timer indicating a countdown associated with the time period.

11. The door system of claim 10, wherein the display is to provide a fault icon when communication with the controller is lost.

12. The door system of claim 10, wherein the symbol has a common shape both when the door system is in a first operational state and when the first operational state is impending, the symbol provided via at least one of different colors or flashing to distinguish when the door system is in the first operational state from when the first operational state is impending.

13. The door system of claim 12, wherein the first state corresponds to one of the door panel moving to the closed position or the door panel moving to the open position.

14. The door system of claim 10, wherein the display corresponds to a two-dimensional array of lights.

15. A door system comprising:

a door panel movable between a closed position and an open position to respectively block and unblock a passageway, the door panel including a sheet extending continuously across a full height of the passageway when in the closed position;

a graphical display positionable adjacent the passageway; and

a controller within an enclosure, the controller to control operation of the door panel, the controller to be in communication with the display to cause the display to provide an icon representative of at least one of a current operational state of the door system or an impending change in the current operational state of the door system, the impending change in the current operational state corresponding to movement of the door panel after a time period, the icon corresponding toe a timer indicating a countdown associated with the time period, the display being larger than the enclosure.
