Abstract

Devices, systems, and methods for predicting fire spread in a facility are described herein. In some examples, one or more embodiments include a computing device comprising a processor and a memory having instructions stored thereon which, when executed by the processor, cause the processor to receive an indication of a fire detected by an event device of a plurality of event devices installed in a facility, sort the plurality of event devices into a plurality of priority levels based on a determined likelihood of fire spread to each of the plurality of event devices, receive data collected by the plurality of event devices during the fire, and provide, via an interface, graphical information descriptive of a spread of the fire based on the received data.

First claim

What is claimed:

1. A computing device for predicting fire spread in a facility, comprising:
a processor; and
a memory having instructions stored thereon which, when executed by the processor, cause the processor to:
receive an indication of a fire detected by an event device of a plurality of event devices installed in a facility;
sort the plurality of event devices into a plurality of priority levels based on a determined likelihood of fire spread to each of the plurality of event devices;
receive data collected by the plurality of event devices during the fire; and
provide, via an interface, graphical information descriptive of a spread of the fire based on the received data.

2. The computing device of claim 1 , including instructions to receive data collected by the plurality of event devices before the detection of the fire by the event device.

3. The computing device of claim 2 , including instructions to receive, from each of the plurality of event devices:
an analog value of detected smoke before the detection of the fire;
an analog value of detected smoke during the fire;
a detected temperature value during the fire;
a sensitivity level before the detection of the fire; and
a sensitivity level during the fire.

4. The computing device of claim 1 , wherein the graphical information descriptive of the fire includes an identification of a first region of the facility where entry by firefighters is recommended.

5. The computing device of claim 1 , wherein the graphical information descriptive of the fire includes an identification of a second region of the facility where entry by firefighters is not recommended.

6. The computing device of claim 1 , wherein the graphical information descriptive of the fire includes a display of a floorplan of the facility including a current location of the fire.

7. The computing device of claim 1 , wherein the graphical information descriptive of the fire includes an indication of an environmental risk factor in a particular location within the facility.

8. The computing device of claim 1 , wherein the graphical information descriptive of the fire includes a predicted spread direction and predicted spread time associated with the fire.

9. A non-transitory computer readable medium having computer readable instructions stored thereon that are executable by a processor to:
receive an indication of a fire detected by an event device of a plurality of event devices installed in a facility;
determine, for each of the plurality of event devices, a respective likelihood of fire spread to that event device;
sort each of the plurality of event devices into a first priority level, a second priority level, or a third priority level based on the respective likelihoods;
receive data collected by event devices in the first priority level during the fire at a first frequency;
receive data collected by event devices in the second priority level during the fire at a second frequency;
receive data collected by event devices in the third priority level during the fire at a third frequency; and
provide, via an interface, graphical information descriptive of a spread of the fire based on the received data.

10. The medium of claim 9 , wherein the event devices in the first priority level, the event devices in the second priority level, and the event devices in the third priority level are cumulatively fewer than a total quantity of event devices installed in the facility.

11. The medium of claim 9 , wherein:
the first priority level is associated with a high likelihood of fire spread;
the second priority level is associated with a moderate likelihood of fire spread;
the third priority level is associated with a low likelihood of fire spread;
the first frequency exceeds the second frequency; and
the second frequency exceeds the third frequency.

12. The medium of claim 11 , wherein the first frequency is between 8 and 12 minutes, the second frequency is between 18 and 22 minutes, and the third frequency is between 28 and 32 minutes.

13. The medium of claim 9 , wherein the graphical information descriptive of the fire includes:
a first color identifying a first region of the facility where entry by firefighters is recommended; and
a second color identifying a second region of the facility where entry by firefighters is not recommended.

14. The medium of claim 9 , including instructions to determine, for each of the plurality of event devices, the respective likelihood of fire spread to that event device based on a location of that event device in the facility.

15. The medium of claim 14 , including instructions to determine, for each of the plurality of event devices, the respective likelihood of fire spread to that event device based on a proximity of that event device to combustible material.

16. A system, comprising:
a plurality of event devices in a facility;
an environmental monitoring system (EMS) in the facility;
a computing device configured to:
receive an indication of a fire detected by an event device of the plurality of event devices;
sort the plurality of event devices into a plurality of priority levels based on a determined likelihood of fire spread to each of the plurality of event devices;
receive data collected by the plurality of event devices during the fire; and
provide, via an interface, graphical information descriptive of a spread of the fire based on the received data.

17. The system of claim 16 , including instructions to receive, from each of the plurality of event devices:
an analog value of detected smoke before the detection of the fire;
an analog value of detected smoke during the fire;
a detected temperature value before the detection of the fire;
a detected temperature value during the fire;
a sensitivity level before the detection of the fire; and
a sensitivity level during the fire.

18. The system of claim 17 , including instructions to determine a first spread possibility associated with a particular event device responsive to:
a determination that the analog value of detected smoke during the fire exceeds the analog value of detected smoke before the detection of the fire by less than 30 percent; or
a determination that the detected temperature value during the fire exceeds the detected temperature value before the detection of the fire by less than 30 percent.

19. The system of claim 18 , including instructions to determine a second spread possibility associated with a particular event device responsive to:
a determination that the analog value of detected smoke during the fire exceeds the analog value of detected smoke before the detection of the fire by between 30 percent and 50 percent; or
a determination that the detected temperature value during the fire exceeds the detected temperature value before the detection of the fire by between 30 percent and 50 percent.

20. The system of claim 19 , including instructions to determine a first spread possibility associated with a particular event device responsive to:
a determination that the analog value of detected smoke during the fire exceeds the analog value of detected smoke before the detection of the fire by 50 percent; or
a determination that the detected temperature value during the fire exceeds the detected temperature value before the detection of the fire by 50 percent.
