System and method for monitoring and suppressing fire
A fire detection and suppression system includes a system controller for determining an initial location of the fire based on fire location information from fire detectors, and then the system controller determines a final location of the fire based on fire location information taking into account spatial and/or angular relationships between the fire detectors and the initial location. The system controller determines a location of the fire and activates monitors to deploy suppressant based on a distance between each of the monitors and the location of the fire. The system controller controls the monitors based on how the suppressant is deployed onto the fire.
1. A fire detection and suppression system, comprising:
a plurality of fire detectors for detecting a fire and generating location information, each of the fire detectors comprising a two-dimensional infrared sensor array;
a plurality of fog/jet monitors for suppressing the fire, the fog/jet monitors having a fog mode and a jet mode; and
a system controller that determines a location of the fire and activates the monitors to deploy suppressant based on a distance between each of the monitors and the location of the fire, the system controller further selectively activating the fog mode and the jet mode based on the distance between each of the monitors and the location of the fire.
2. A fire detection and suppression method, comprising:
detecting a fire and generating location information with a plurality of fire detectors, each of the fire detectors comprising a two-dimensional infrared sensor array;
a system controller determining a location of the fire based on the fire detectors and activating monitors to deploy suppressant based on a distance between each of the monitors and the location of the fire; and
the system controller selectively activating a fog mode and a jet mode of the monitors based on the distance between each of the monitors and the location of the fire.
3. The method as claimed in claim 2 , further comprising determining an initial location of the fire based on the fire location information from the fire detectors, then determining a final location of the fire based on the fire location information taking into account spatial and/or angular relationships between the fire detectors and the initial location.
4. The method as claimed in claim 2 , further comprising selecting a few of the fire detectors that are closest to an initial location of the fire, and then determining a final location based on the few fire detectors.
5. The method as claimed in claim 2 , wherein the few fire detectors is a pair of fire detectors.
6. The method as claimed in claim 2 , further comprising selecting a few fire detectors based on a sum of the distances between the few fire detectors and the location of the fire.
7. The method as claimed in claim 2 , further comprising determining a final location based on weighted average of the location information from the fire detectors, the weighted average being based on distance between the fire detectors and an initial location of the fire.
8. The method as claimed in claim 4 , further comprising determining the final location based on an angular direction of the fire relative to the fire detectors.
9. The fire detection and suppression system as claimed in claim 1 , wherein the system controller determines an initial location of the fire based on the fire location information from the fire detectors, then determines a final location of the fire based on the fire location information taking into account spatial and/or angular relationships between the fire detectors and the initial location.
10. The fire detection and suppression system as claimed in claim 9 , wherein the system controller selects a few of the fire detectors that are closest to the initial location of the fire, and determines the final location based on the few fire detectors.
11. The fire detection and suppression system as claimed in claim 10 , wherein the few fire detectors is a pair of fire detectors.
12. The fire detection and suppression system as claimed in claim 9 , wherein the system controller selects a few fire detectors based on a sum of the distances between the few fire detectors and the initial location of the fire.
13. The fire detection and suppression system as claimed in claim 9 , wherein the system controller determines the final location based on weighted average of the location information from the fire detectors, the weighted average being based on distance between the fire detectors and the initial location of the fire.
14. The fire detection and suppression system as claimed in claim 9 , wherein the system controller determines the final location based on an angular direction of the fire relative to the fire detectors.
