MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051264 A) filed by Dayananda Sagar College Of Engineering, Bangalore, Karnataka, on April 22, for 'system and method for fully autonomous fire detection, spatial localization, wireless communication and drone-based suppression.'
Inventor(s) include Dr. Rudresh M; Maithri K; Krishika Venkatesh; Dr. Ashwin C Gowda; and Dr. Ravikumar M.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an autonomous system for detecting fire in a monitored environment, determining the precise spatial location of the fire within that environment, issuing an audio alert, transmitting the fire location data wirelessly, and dispatching an unmanned aerial vehicle to the detected location to physically suppress the fire without any human intervention at any stage of the process. The system comprises a camera module mounted at a fixed overhead position above a monitored surface area, a single-board processing unit running a deep learning based fire detection model, a coordinate mapping module that converts pixel-space detections to real-world spatial measurements in centimetres, a wireless transceiver for transmitting fire location data to the aerial vehicle, an audio alert module, and an unmanned aerial vehicle equipped with a paired wireless receiver, a dedicated flight controller, an onboard microcontroller, and a fire suppression mechanism. Upon detection of fire with a confidence value at or above a defined threshold, the system extracts the center coordinates of the detection bounding in pixel space and converts them to centimetre-accurate real-world coordinates using a pre-calibrated pixels-per-centimetre constant derived from the fixed camera mounting height. The unmanned aerial vehicle receives the transmitted coordinates, decodes them using its onboard microcontroller, commands the flight controller to navigate to the corresponding position above the monitored surface, descends to a defined operating height, and activates the onboard suppression mechanism to extinguish the fire. A redundancy protocol ensures repeated transmission of coordinates for as long as fire detection persists, directing the aerial vehicle to make repeated suppression attempts if required. The invention achieves spatial coordinate accuracy within a few centimetres under controlled conditions and demonstrates fire-to-alert response times of under three seconds."
