System for detecting fire outbreaks comprising a plurality of detection devices forming a meshing

A detection device for a fire outbreak detection system, wherein the detection device comprises:

• a protective case;
• at least one sensor housed in the case, in the form of an infrared-type camera;
• first communication device which is cooperable with a second remote communication device;
• a processing unit coupled to the sensor and to the first communication device, the processing unit being configured to:
• acquire, via the at least one sensor, infrared images of an area to be monitored at regular intervals;
• detect a predetermined infrared level threshold in a first image;
• compare an infrared level of a second image following the first image to detect a localized increase in infrared radiation;
• in response to a localized increase in infrared radiation being detected, transmit to the second communication device, via the communication channel, a digital warning signal including a unique identifier of the detection device and geolocation data;
• record in a recording device the geolocation data during installation of the detection device in the area to be monitored, either automatically by a global positioning system (GPS) module or by manual entry;
• and
• place the first communication device and/or the communication channel periodically in a standby mode, in response to being not used, the placing in standby mode including interrupting communications between the detection device and the second communication device;
• and
• the recording device for recording the unique identifier and the geolocation data.

A method for detecting a fire outbreak in the area to be monitored by using the fire outbreak detection system comprising:

• a plurality of detection devices forming a meshing of an area to be monitored, each detection device comprising a recording device able to memorise a unique identifier, at least one sensor of a physical characteristic of a fire outbreak, a processing unit and a first communication device;
• a computer platform comprising a database relating to the detection devices and listing the unique identifiers of all detection devices and a second communication device which is cooperable with the first communication device to form a communication channel;
• wherein each sensor of each detection device comprises an infrared-type camera, and wherein each detection device is configured to:
• acquire, via the at least one sensor, infrared images of the area to be monitored at regular intervals;
• detect a predetermined infrared level threshold in a first image;
• compare an infrared level of a second image following the first image to detect a localised increase in infrared radiation;
• and
• in response to a localised increase in infrared radiation being detected, transmit to the computer platform, via the communication channel, a digital warning signal including the unique identifier of the detection device and geolocation data stored in the recording device, and
• wherein the method comprises:
• installing, in the area to be monitored, the plurality of detection devices in order to define the meshing of the area to be monitored, including the detection device recording in the recording device geolocation data during installation of the detection device in the area to be monitored, either automatically by a global positioning system (GPS) module or by manual entry;
• acquiring, via each sensor, the infrared images of the area to be monitored at the regular intervals;
• detecting the predetermined infrared level threshold in the first image;
• comparing the infrared level of the second image following the first image to detect the localised increase in infrared radiation;
• in response to the localised increase in infrared radiation being detected, transmitting to the computer platform, via the communication channel, the digital warning signal including the unique identifier of the detection device and the geolocation data stored in the recording device;
• and
• placing the first communication device and/or the communication channel periodically in a standby mode, in response to being not used, the placing in standby mode including interrupting communications between the computer platform and the at least one detection device.
