Abstract

A system includes a first sensor configured to identify information regarding an emergency condition associated with a structure and a second sensor configured to identify an occupancy pattern regarding the structure. The system also includes a processor operatively coupled to the first sensor, the second sensor, and a transceiver. The processor is configured to determine a severity of the emergency condition based at least in part on the information regarding the emergency condition and prioritize rescues within the structure based at least in part on the occupancy pattern. The system also includes the transceiver which is configured to transmit an identification of the emergency condition, a location of the structure, the occupancy pattern, the prioritization of rescues, and the severity of the emergency condition.

First claim

What is claimed is:

1. An evacuation system comprising:
a first sensory node, the first sensory node comprising a condition sensor;
a second sensory node;
a decision node in communication with the first sensory node and the second sensory node, the decision node comprising a processor and a memory, the memory of the decision node comprising instructions that when executed by the processor, cause the decision node to:
receive condition sensor data from the first sensory node;
determine an evacuation condition from the sensor data and using the sensor data, determine a hazard type represented by the evacuation condition;
identify a location of the first sensory node;
identify a plurality of evacuation routes from the location of the first sensory node to a plurality of exits;
select one of the plurality of evacuation routes based on the determined hazard type;
generate a notification comprising the evacuation condition and selected evacuation route; and
transmit the generated notification.

2. The evacuation system of claim 1 , where the location of the first sensory node is retrieved from the memory.

3. The evacuation system of claim 1 , where the location of the first sensory node is received from the sensory node.

4. The evacuation system of claim 3 , where the first sensory node determines its location from location data stored in the sensory node during installation.

5. The evacuation system of claim 3 , where the first sensory node comprises a GPS receiver and determines its location using the GPS receiver.

6. The evacuation system of claim 1 , where the location of the first sensory node is determine using a relative coordinate distance from the second sensory node.

7. The evacuation system of claim 1 , where the first sensory node further comprises an occupancy sensor and the occupancy level detected by the first sensory node and a capacity of each of the plurality of evacuation routes is considered during the selection of an evacuation route.

8. The evacuation system of claim 1 , further comprising instructions which cause the decision node to identify at least one sensory node along the selected evacuation route and if the identified sensory node indicates an evacuation condition present at the identified sensory node, the instructions cause the decision node to select an alternate evacuation route to avoid the identified sensory node.

9. A method of determining an evacuation route comprising:
receiving at a decision node, condition sensor data from a first sensory node;
determining an evacuation condition from the sensor data;
determining a hazard type from the sensor data;
identifying a location of the first sensory node;
identifying a plurality of evacuation routes from the location of the first sensory node to a plurality of exits;
selecting one of the plurality of evacuation routes based on the determined hazard type;
generating a notification comprising the evacuation condition and selected evacuation route; and
transmitting the generated notification.

10. The method of claim 9 , further comprising retrieving the location of the first sensory node from a memory of the decision node.

11. The method of claim 9 , further comprising receiving the location of the first sensory node from the sensory node.

12. The method of claim 11 , where the location of the first sensory node is determined from location data entered into the sensory node during installation.

13. The method of claim 11 , where the location of the first sensory node is determined using a GPS receiver comprised by the first sensory node.

14. The method of claim 9 , further comprising determining the location of the first sensory node using a relative coordinated distance from a second sensory node.

15. The method of claim 9 , further comprising detecting an occupancy level by the first sensory node and considering the detected occupancy when selecting an evacuation route.

16. The method of claim 9 , further comprising identifying at least one sensory node along the selected evacuation route and if the identified sensory node indicates an evacuation condition present at the identified sensory node, selecting an alternate evacuation route to avoid the identified sensory node.

17. A non-transitory computer-readable media comprising computer-readable instructions stored thereon that when executed by a processor associated with a decision node located within a structure, cause the processor to:
receive condition sensor data from a first sensory node;
determine an evacuation condition from the sensor data;
determine a hazard type from the sensor data;
identify a location of the first sensory node;
identify a plurality of evacuation routes from the location of the first sensory node to a plurality of exits;
select one of the plurality of evacuation routes based on the determined hazard type;
generate a notification comprising the evacuation condition and selected evacuation route; and
transmit the generated notification.

18. The non-transitory computer-readable media of claim 17 , wherein the computer-readable instructions further comprise instructions that cause the processor to receive the location of the first sensory node from the sensory node.

19. The non-transitory computer-readable media of claim 17 , wherein the computer-readable instructions further comprise instructions that cause the processor to:
detect an occupancy level by the first sensory node; and
consider the detected occupancy when selecting an evacuation route.

20. The non-transitory computer-readable media of claim 17 , wherein the computer-readable instructions further comprise instructions that cause the processor to:
identify at least one sensory node along the selected evacuation route; and
if the identified sensory node indicates an evacuation condition present at the identified sensory node, select an alternate evacuation route to avoid the identified sensory node.
