Abstract

Systems and methods of using a fire spread forecast and BIM to guide occupants using smart signs are provided. Some methods can include receiving a first signal indicative of a first location of a fire event in a monitored region, using the first location and BIM information to project an area into which the fire event will spread in the monitored region, and identifying at least one smart sign in the monitored region to enable for guiding an occupant in the monitored region to an exit door in the monitored region while avoiding the first location and the area.

First claim

What is claimed is:

1. A method comprising:
receiving a first signal indicative of a first location of a fire event in a monitored region;
using the first location and building information modeling (BIM) information to project an area into which the fire event will spread in the monitored region; and
identifying at least one smart sign in the monitored region to enable for guiding an occupant in the monitored region to an exit door in the monitored region while avoiding the first location and the area.

2. The method of claim 1 further comprising receiving the first signal from a fire detector in the monitored region.

3. The method of claim 1 further comprising receiving the BIM information from a BIM device.

4. The method of claim 1 further comprising retrieving the BIM information from a database device.

5. The method of claim 1 further comprising using the first location and the BIM information to simulate fire spread vectors for the fire event.

6. The method of claim 1 further comprising:
receiving a second signal indicative of a second location of the occupant in the monitored region; and
identifying the at least one smart sign in the monitored region to enable for guiding the occupant from the second location to the exit door in the monitored region while avoiding the first location and the projected area into which the fire event will spread.

7. The method of claim 1 further comprising transmitting a second signal to the at least one smart sign to enable the at least one smart sign.

8. The method of claim 1 further comprising identifying at a second smart sign in the monitored region to disable.

9. The method of claim 1 further comprising:
identifying the at least one smart sign from a plurality of smart signs in the monitored region to enable; and
transmitting a second signal to the at least one smart sign.

10. A system comprising:
a transceiver;
a programmable processor; and
executable control software stored on a non-transitory computer readable medium,
wherein the transceiver receives a first signal indicative of a first location of a fire event in a monitored region,
wherein the programmable processor and the executable control software use the first location and building information modeling (BIM) information to project an area into which the fire event will spread in the monitored region, and
wherein the programmable processor and the executable control software identify at least one smart sign in the monitored region to enable for guiding an occupant in the monitored region to an exit door in the monitored region while avoiding the first location and the area.

11. The system of claim 10 wherein the transceiver receives the first signal from a fire detector in the monitored region.

12. The system of claim 10 wherein the transceiver receives the BIM information from a BIM device.

13. The system of claim 10 further comprising a database device, wherein the programmable processor and the executable control software retrieve the BIM information from the database device.

14. The system of claim 10 wherein the programmable processor and the executable control software use the first location and the BIM information to simulate fire spread vectors for the fire event.

15. The system of claim 10 wherein the transceiver receives a second signal indicative of a second location of the occupant in the monitored region, and
wherein the programmable processor and the executable control software identify the at least one smart sign in the monitored region to enable for guiding the occupant from the second location to the exit door in the monitored region while avoiding the first location and the area.

16. The system of claim 10 wherein the programmable processor and the executable control software instruct the transceiver to transmit a second signal to the at least one smart sign to enable the at least one smart sign.

17. The system of claim 10 wherein the programmable processor and the executable control software identify a second smart sign in the monitored region to disable.

18. The system of claim 10 wherein the programmable processor and the executable control software identify the at least one smart sign from a plurality of smart signs in the monitored region to enable and instruct the transceiver to transmit a second signal to the at least one smart sign.

19. A system comprising:
a fire detection system in a monitored region;
a building information modeling (BIM) device;
a simulator and notification system; and
a plurality of smart signs in the monitored region,
wherein the simulator and notification system receives a first signal from the fire detection system and a second signal from the BIM device,
wherein the simulator and notification system uses the first signal and the second signal to project an area into which a fire event detected by the fire detection system will spread in the monitored region, and
wherein the simulator and notification system uses the first signal, the second signal, and the area to identify at least one of the plurality of smart signs to enable for guiding an occupant in the monitored region to an exit door in the monitored region while avoiding a location of the fire event and the area.

20. The system of claim 19 wherein each of the plurality of smart signs includes at least one light that can be enabled or disabled or at least one diagram or word that can be displayed or hidden.
