AI Technical Summary
The existing escape routes could not be protected in time after the fire spread, causing the temperature to rise rapidly and endangering the safety of evacuees and firefighters.
Temperature sensors, water pipes, and atomizing nozzles are installed in the escape routes. Smoke sensors detect smoke and activate smoke exhaust fans to draw out the smoke. After the temperature sensor detects the fire, it drives the solenoid valve to open the water pipe to supply water to the atomizing nozzles, spraying out tiny water droplets to cover the fire source and prevent the fire from spreading.
Effectively curb the spread of fire, reduce the temperature of passageways, decrease the concentration of smoke and toxic gases, and ensure safe escape.
