In plain words
In a building fire, detection is only half the problem — most casualties happen in the evacuation. India's ADSI data recorded roughly 17,700 accidental fire deaths in 2015 alone, about 48 a day. This patent's answer is a building that doesn't just ring a bell — it watches, thinks, guides and fights back.
An IoT network of temperature sensors, smoke-density detectors and thermal/video cameras covers every floor, reporting to a two-level control hierarchy: a Floor Control Centre per floor handles minor, localised incidents, while the Main Control Centre takes over for major, multi-area fires.
When a major fire is identified, the Main Control Centre computes the safest evacuation path per floor and sends it to occupants by text message — dynamically re-routing as the fire spreads. Meanwhile it fights the fire directly with wall-mounted targeted water and foam jets, and a remote-controlled robot on each floor that clears debris and douses flames, while firefighting officials are alerted with the fire's exact nature and location.
How it works
- Sense everythingTemperature sensors, smoke detectors and thermal/video cameras monitor every floor continuously.
- Escalate in two levelsFloor Control Centres manage minor localised incidents; the Main Control Centre takes command of major multi-area fires.
- Guide people outThe safest escape route is computed per floor, texted to occupants, and updated live as the fire moves through the building.
- Fight back while they fleeWall-mounted targeted water/foam jets and a per-floor remote-controlled robot clear debris and douse flames; firefighters get the exact location and nature of the blaze.
Why it matters
Fire codes worldwide still rely on static exit signs and one-size-fits-all alarms designed a century ago. A building that senses where its fire is, reroutes its people around it in real time, and deploys robots against the flames is the obvious next step — and this granted patent sits on that step.
