Abstract

A system includes one or more computer processors configured to receive structure data for a building, receive location data relating to a plurality of sensors positioned throughout the building, receive data from the sensors, and determine one or more of a safe space within the building and a safe evacuation route through the building as a function of the building structure, the location of the plurality of sensors, and the sensor data. The system further includes a plurality of display units positioned throughout the building and configured to display one or more of a message relating to an event within the building, an instruction on where to proceed in the building, and symbols indicating a direction for evacuation out of the building as a function of one or more of the safe space and the safe evacuation route.

First claim

1 . A system comprising:
a computer processor configured to receive structure data for a building; a computer processor configured to receive location data relating to a plurality of sensors positioned throughout the building; a computer processor configured to receive data from the sensors; a computer processor configured to determine one or more of a safe space within the building and a safe evacuation route through the building as a function of the building structure, the location of the plurality of sensors, and the sensor data; and a plurality of display units positioned throughout the building and configured to display one or more of a message relating to an event within the building, an instruction on where to proceed in the building, and symbols indicating a direction for evacuation out of the building as a function of one or more of the safe space and the safe evacuation route.

2 . The system of claim 1 , wherein the structure data comprises Building Information Modeling (BIM) data.

3 . The system of claim 1 , wherein the sensors comprise one or more of a smoke detector, a toxic gas detector, a heat detector, a video surveillance device, an audio surveillance device, a motion detector, and an infra-red sensing device.

4 . The system of claim 1 , wherein the display units comprise light emitting diode (LED) display units or other changeable message display units.

5 . The system of claim 4 , wherein the LED display units or other changeable message display units comprise pre-existing information display units installed in the building.

6 . The system of claim 1 , comprising a computer processor configured to display the safe space by displaying a floor plan grid of the safe space on one or more of the display units.

7 . The system of claim 6 , comprising a computer processor configured to display on the one or more display units a model-based prediction of an extent of the event.

8 . The system of claim 6 , comprising a computer processor configured to indicate on the one or more display units an area proximate to a sensor reporting data indicating the event.

9 . The system of claim 8 , wherein the evacuation route is determined by examining the safe space and the area proximate to the sensor reporting data indicating the event; and for each of the plurality of display units, displaying a message announcing and identifying the event and displaying instructions for people.

10 . The system of claim 9 , wherein the instructions comprise a display of an optimal route for evacuation from the building.

11 . The system of claim I, wherein the plurality of display units are configured to display the direction towards the event and a distance to the event.

12 . The system of claim 1 , wherein the instruction on where to proceed and the symbols indicating a direction are a function of a location and an orientation of the display units.

13 . The system of claim 1 , comprising a computer processor configured to estimate smoke propagation, heat propagation, toxic gas propagation, or an intruder path, and to display one or more of a message relating to the event within the building, an instruction on where to proceed in the building, and symbols indicating a direction for evacuation out of the building as a function of the estimated smoke propagation, heat propagation, toxic gas propagation, or intruder path.

14 . The system of claim 1 , comprising a computer processor configured with a natural language generator for generation of the message.

15 . A process comprising:
receiving into a computer processor structure data for a building; receiving into the computer processor location data relating to a plurality of sensors positioned throughout the building; receiving into the computer processor data from the sensors; determining using the computer processor one or more of a safe space within the building and a safe evacuation route through the building as a function of the building structure, the location of the plurality of sensors, and the sensor data; and displaying on a plurality of display units positioned throughout the building one or more of a message relating to an event within the building, an instruction on where to proceed in the building, and symbols indicating a direction for evacuation out of the building as a function of one or more of the safe space and the safe evacuation route.

16 . The process of claim 15 , wherein the instruction on where to proceed and the symbols indicating a direction are a function of a location and an orientation of the display units.

17 . The process of claim 15 , estimating smoke propagation, heat propagation, toxic gas propagation, or an intruder path, and displaying one or more of a message relating to the event within the building, an instruction on where to proceed in the building, and symbols indicating a direction for evacuation out of the building as a function of the estimated smoke propagation, heat propagation, toxic gas propagation, or intruder path.

18 . A computer readable medium comprising instructions that when executed by a processor execute a process comprising:
receiving structure data for a building; receiving location data relating to a plurality of sensors positioned throughout the building; receiving data from the sensors; determining one or more of a safe space within the building and a safe evacuation route through the building as a function of the building structure, the location of the plurality of sensors, and the sensor data; and displaying on a plurality of display units positioned throughout the building one or more of a message relating to an event within the building, an instruction on where to proceed in the building, and symbols indicating a direction for evacuation out of the building as a function of one or more of the safe space and the safe evacuation route.

19 . The computer readable medium of claim 18 , wherein the instruction on where to proceed and the symbols indicating a direction are a function of a location and an orientation of the display units.

20 . The computer readable medium of claim 18 , comprising instructions for estimating smoke propagation, heat propagation, toxic gas propagation, or an intruder path, and displaying one or more of a message relating to the event within the building, an instruction on where to proceed in the building, and symbols indicating a direction for evacuation out of the building as a function of the estimated smoke propagation, heat propagation, toxic gas propagation, or intruder path.
