AI Technical Summary

Technical Problem

Existing electrical fire hazard early warning systems struggle to achieve low false alarm rates, timely and reliable judgment during the early stages of fault development. Smoke detectors have delayed responses, point-type heat detectors have limited coverage, and single electrical parameter monitoring is susceptible to interference and has a high false alarm rate.

Method used

By monitoring multimodal data, electromagnetic radiation signals are collected, and anomaly detectors are used to calculate Mahalanobis distance to identify abnormal radiation events, classify radiation sources, and perform spatial registration by combining infrared thermal images and visible light images to trigger graded alarms.

Benefits of technology

It improves the timeliness and reliability of early warnings during the early stages of fire hazard development, reduces false alarm rates, and enables early and accurate identification of fire hazards.

Abstract

This invention discloses a method and system for intelligent monitoring and early warning of fire hazards based on multimodal data, relating to the field of fire alarms. The method includes: acquiring electromagnetic radiation signals in a target area; determining abnormal radiation events and classifying radiation sources by calculating the Mahalanobis distance with an electromagnetic fingerprint baseline to obtain abnormal detection data; grouping detection data using at least three electromagnetic receivers, performing cross-verification of abnormal detection data, calculating the detection distance based on pulse arrival time, and solving for radiation source coordinates using multiple hyperboloid intersections; acquiring heat map data and image frame data, performing spatial registration based on the radiation source coordinates, performing multi-source joint judgment, and managing fire hazard alarms. This application addresses the problem in existing electrical fire hazard early warning systems that struggle to achieve low false alarm rates, timely and reliable judgment during the early stages of fault development, thus improving the timeliness, reliability, and low false alarm rate of early warnings during the early stages of fault evolution.
