Door lock with display unit
Provided are electronic door locks, systems, and computer implemented methods of use. In one example, the electronic door lock includes a locking mechanism configured to change a state of a door of a room between a locked state and an unlocked state. The electronic door lock further includes a communications interface configured to communicate wirelessly or wired with one or more fire devices. The one of more fire devices are configured to transmit a wireless or wired alert signal to the communications interface in response to detecting an occurrence of fire. The electronic door lock further includes a display unit configured to display an alert upon the communications interface receiving the wireless alert signal from the one or more fire devices, and configured to display an indication as to occupancy of the room.
1. An electronic door lock controller operable to perform door lock control operations comprising:
receiving an emergency-state signal from one or more emergency-state sensors that have detected an emergency-state within an area that can be entered through a door;
responsive to the emergency-state signal:
generating an occupancy alert that indicates that the area is occupied;
generating an emergency-state alert that indicates that an emergency has occurred within the area; and
controlling a locking mechanism to change a state of the door between a locked state and an unlocked state; and
controlling a display unit to display the emergency-state alert and the occupancy alert to a person who is outside the area when the door is closed.
2. The electronic door lock controller of claim 1 , wherein the display unit is integrated with an electronic door lock positioned on an outside surface of the door.
3. The electronic door lock controller of claim 2 , wherein generating the occupancy alert is based at least in part on an analysis of an embedded radio frequency identification (RFID) or near field communication (NFC) reader operable to read one or more RFID or NFC enabled door keys of the door.
4. The electronic door lock controller of claim 1 , wherein the display unit is operable to:
emit a first color via one or more light emitting diodes (LEDs) in response to the emergency-state alert; and
emit a second color via the one or more LEDs in response to the occupancy alert.
5. The electronic door lock controller of claim 4 , wherein the display unit is operable to emit the second color only if the controller receives the emergency-state signal.
6. The electronic door lock controller of claim 1 , wherein the electronic door lock controller is integrated within an electronic door lock.
7. The electronic door lock controller of claim 1 , wherein the electronic door lock controller comprises a central control system.
8. A computer-implemented method comprising:
receiving, using an electronic door lock controller, an emergency-state signal from one or more emergency-state sensors that have detected an emergency-state within an area that can be entered through a door;
responsive to the emergency-state signal:
generating an occupancy alert that indicates that the area is occupied;
generating an emergency-state alert that indicates that an emergency has occurred within the area; and
controlling a locking mechanism to change a state of the door between a locked state and an unlocked state; and
controlling a display unit to display the emergency-state alert and the occupancy alert to a person who is outside the area when the door is closed.
9. The computer-implemented method of claim 8 , wherein the display unit is operable to:
emit a first color via one or more light emitting diodes (LEDs) in response to the emergency-state alert; and
emit a second color via the one or more LEDs in response to the occupancy alert.
10. The computer-implemented method of claim 9 , wherein the display unit is operable to emit the second color only if the electronic door lock controller receives the emergency-state signal.
11. The computer-implemented method of claim 8 , wherein the display unit is integrated with an electronic door lock positioned on an outside surface of the door.
12. The computer-implemented method of claim 8 , wherein generating the occupancy alert is based at least in part on an analysis of an embedded radio frequency identification (RFID) or near field communication (NFC) reader operable to read one or more RFID or NFC enabled door keys of the door.
