Abstract

A system and a method for determining one or more safe evacuation paths in an event of fire. A method includes receiving measurements of parameter/s from one or more detectors. The one or more detectors detect parameter/s in an event of fire in a premises and are positioned at each of a plurality of evacuation paths inside the premises. The method further includes determining one or more safe evacuation paths from the plurality of evacuation paths inside the premises based on the measurements of the parameter/s. The method also includes displaying an indication of each of the one or more safe evacuation paths on an interface of a user device based on the determination.

Claims (26)

1. A system comprising:

one or more detectors positioned at each of a plurality of evacuation paths inside a premises, wherein the one or more detectors are fire detectors, heat detectors or smoke detectors, and the parameter is a fire parameter, a heat parameter, and/or a smoke parameter, the one or more detectors comprising:

one or more sensors adapted to detect a parameter in an event of fire in the premises; and

a transmitter adapted to transmit measurements of the parameter to a hand-held, portable user device; and

the user device comprising:

a determination unit adapted to determine one or more safe evacuation paths from the plurality of evacuation paths inside the premises based on the measurements received from the one or more detectors; and

an interface adapted to display an indication of each of the one or more safe evacuation paths based on the determination;

the determination unit is further adapted to determine one or more unsafe evacuation paths from the plurality of evacuation paths inside the premises and the interface is further adapted to display an indication of each of the one or more unsafe evacuation paths based on the determination;

wherein the one or more safe evacuation paths are determined if the measurements of the parameter are below a first pre-defined threshold, and the one or more unsafe evacuation paths are determined if the measurements of the parameter are above a second pre-defined threshold.

2. The system of claim 1 , wherein the transmitter is adapted to transmit the measurements of the parameter to a control panel.

3. The system of claim 2 , wherein the control panel transmits the measurements of the parameter to a server, wherein the server transmits the measurements of the parameter to the user device.

4. The system of claim 2 , wherein the control panel transmits the measurements of the parameter to a server, wherein the server determines one or more safe evacuation paths from the plurality of evacuation paths based on the measurements.

5. The system of claim 4 , wherein the server transmits an indication of each of the one or more safe evacuation paths to a user device to display the indication on the interface.

6. The system of claim 1 , wherein the one or more safe evacuation paths are indicated with a first color on the interface of the user device.

7. The system of claim 1 , wherein the one or more unsafe evacuation paths are indicated with a second color on the interface of the user device.

8. The system of claim 1 , wherein the one or more detectors transmit the measurements of the parameter to the user device through a Wi-Fi communication or a cellular communication.

9. The system of claim 1 , wherein the user device receives an identifier associated with each of the one or more detectors and a location of each of the one or more detectors inside the premises.

10. A method comprising:

receiving measurements of parameter from one or more detectors, wherein the one or more detectors are fire detectors, heat detectors or smoke detectors, and the parameter is a fire parameter, a heat parameter, and/or a smoke parameter, the one or more detectors detect parameter in an event of fire inside a premises and are positioned at each of a plurality of evacuation paths inside the premises;

determining one or more safe evacuation paths from the plurality of evacuation paths inside the premises based on the measurements of the parameter; and

displaying an indication of each of the one or more safe evacuation paths on an interface of a hand-held, portable user device based on the determination

wherein the one or more safe evacuation paths are determined if the measurements of the parameter are below a first pre-defined threshold;

wherein the user device determines one or more unsafe evacuation paths from the plurality of evacuation paths inside the premises and the interface is adapted to display an indication of each of the one or more unsafe evacuation paths based on the determination;

wherein the one or more unsafe evacuation paths are determined if the measurements of the parameter are above a second pre-defined threshold.

11. The method of claim 10 , wherein the one or more safe evacuation paths are indicated with a first color on the interface of the user device and the one or more unsafe evacuation paths are indicated with a second color on the interface of the user device.

12. A computer readable medium comprising one or more processors and a memory coupled to the one or more processors, the memory storing instructions executed by the one or more processors, the one or more processors configured to perform the method of claim 10 .
