AI Technical Summary

Technical Problem

Existing automatic tracking fire suppression systems suffer from problems such as high false alarm rates, difficulty in identifying the real fire source, low fire suppression efficiency, and limited system reliability in complex environments. In particular, in enclosed or semi-enclosed spaces such as underground garages and multi-story parking lots, sensors are easily affected by environmental interference and fire extinguishing agents cannot accurately hit the core fire area.

Method used

By employing a multi-sensor detection module combined with an edge computing module, a multispectral detection array is constructed using a visible light camera, an infrared thermal imaging sensor, and an ultraviolet flame sensor. An adaptive fusion algorithm based on feature confidence is used to suppress environmental interference. Combined with a fire spread prediction model and a model prediction control algorithm, the spray parameters are dynamically adjusted to achieve accurate fire source identification and active fire suppression.

Benefits of technology

It improves the accuracy of fire source identification and the first-hit rate of extinguishing agents, reduces false alarm rate and resource waste, enhances fire extinguishing efficiency and system safety, and is suitable for automatic tracking fire extinguishing in complex environments.

Abstract

This invention discloses an automatic tracking and positioning control device, method, and system for fire suppression, aiming to solve the problems of susceptible sensing to interference, delayed tracking response, insufficient spraying accuracy, and poor system coordination in existing fire suppression systems. The method includes: collecting data through visible light, infrared, and ultraviolet sensors; using an adaptive fusion algorithm to suppress interference and identify the actual fire source, and then calculating its three-dimensional coordinates; inputting the coordinates into a fire spread prediction model to obtain a predicted aiming point, and using a model predictive control algorithm to generate a smooth and fast gimbal tracking trajectory; calculating the spray angle and flow rate based on the fire source distance and ambient airflow, and compensating for trajectory deviation through a kinematic model to achieve precise variable spraying; the entire process is executed by an edge computing node in real-time closed-loop control, coordinating with the cloud and neighboring nodes, and operating autonomously in the event of network anomalies. This invention significantly improves the accuracy, timeliness, reliability, and collaborative efficiency of fire suppression.
