Abstract

Systems and methods for wayfinding in hazardous environments are disclosed. In one embodiment, a method for wayfinding in a hazardous environment may include: (1) receiving, at an emergency response computer program executed by an electronic device, a plurality of real time streams of data, each real time stream of data from a sensing device in an area; (2) detecting, by the emergency response computer program, an alarm condition in the area based on the real-time streams of data; (3) determining, by the emergency response computer program, that the alarm condition satisfies an alarm condition rule; (4) calculating, by the emergency response computer program, a plurality of routes to an egress point from the area; and (5) controlling, by the emergency response computer program, a digital signage in the area to display one of the plurality of routes the egress point.

First claim

1 . A method for wayfinding in a hazardous environment, comprising:
receiving, at an emergency response computer program executed by an electronic device, a plurality of real-time streams of data, each real-time stream of data from a sensing device in an area; detecting, by the emergency response computer program, an alarm condition in the area based on the real-time streams of data; determining, by the emergency response computer program, that the alarm condition satisfies an alarm condition rule; calculating, by the emergency response computer program, a plurality of routes to an egress point from the area using a graph representing the area comprising a plurality of nodes and a plurality of edges connecting the nodes, wherein the nodes represent sub-areas within the area, and the edges represent paths between two of the nodes, and the edges are weighted based on a speed or flow between nodes from evacuation drill data; and controlling, by the emergency response computer program, a digital signage in the area to display one of the plurality of routes the egress point.

2 . The method of claim 1 , wherein the sensing devices comprise a temperature sensor, a smoke detector, and/or a carbon monoxide detector.

3 . The method of claim 1 , wherein the sensing devices comprise a microphone.

4 . The method of claim 1 , wherein the sensing devices comprise an imaging device.

5 . The method of claim 1 , wherein the real-time streams comprise raw data from the sensing device, wherein the raw data comprises a sensing device identifier, a sensed data, and a timestamp.

6 . The method of claim 1 , wherein the real-time streams comprise a trigger event comprising a sensing device identifier, a trigger condition, and a timestamp.

7 . The method of claim 1 , wherein the alarm condition is associated with a fire or a violence incident.

8 . The method of claim 1 , wherein the alarm condition rule comprises a breach period requirement.

9 . (canceled)

10 . The method of claim 1 , further comprising:
receiving, by the emergency response computer program, a location of an electronic device in the area; calculating, by the emergency response computer program, a route from the location of the electronic device to the egress point from the area; and sending, by the emergency response computer program, the route to the electronic device.

11 . The method of claim 1 , further comprising:
monitoring, by the emergency response computer program, a traffic volume to the egress point; determining, by the emergency response computer program, that the traffic volume exceeds a threshold; calculating, by the emergency response computer program, a second route to a second egress point; and controlling, by the emergency response computer program, a subset of the digital signage in the area to display the second route to the second egress point.

12 . A system, comprising:
a plurality of sensing devices in an area; and an electronic device comprising a memory storing an emergency response computer program and a computer processor; wherein:
the emergency response computer program receives a real-time stream of data from each of the plurality of sensing devices;
the emergency response computer program detects an alarm condition in the area based on the real-time streams of data;
the emergency response computer program determines that the alarm condition satisfies an alarm condition rule;
the emergency response computer program calculates a plurality of routes to an egress point from the area using a graph representing the area comprising a plurality of nodes and a plurality of edges connecting the nodes, wherein the nodes represent sub-areas within the area, and the edges represent paths between two of the nodes, and the edges are weighted based on a speed or flow between nodes from evacuation drill data; and
the emergency response computer program controls a digital signage or lighting in the area to display or illuminate one of the plurality of routes the egress point.

13 . The system of claim 12 , wherein the sensing devices comprise a temperature sensor, a smoke detector, a carbon monoxide detector, an imaging device and/or a microphone.

14 . The system of claim 12 , wherein the electronic device is a cloud-based electronic device.

15 . The system of claim 12 , wherein the real-time streams comprise raw data from the sensing device, wherein the raw data comprises a sensing device identifier, a sensed data, and a timestamp.

16 . The system of claim 12 , wherein the real-time streams comprise a trigger event comprising a sensing device identifier, a trigger condition, and a timestamp.

17 . The system of claim 12 , wherein the alarm condition is associated with a fire or a violence incident.

18 . The system of claim 12 , wherein the alarm condition rule comprises a breach period requirement.

19 . (canceled)

20 . The system of claim 12 , wherein the emergency response computer program further receives a location of an electronic device in the area, calculates a route from the location of the electronic device to the egress point from the area, and sends the route to the electronic device.
