Multi-physical fused fire monitoring system and method thereof for predicting fire probability of occurrence

Abstract

The invention discloses a multi-physical fused fire monitoring system and method thereof for predicting fire probability of occurrence. The monitoring system comprises a point type smoke sensing detector, a point type temperature sensing detector, a line type beam smoke sensing detector, an air-breathing smoke sensing fire detector, a cable line type temperature sensing detector, a cable multi-point type temperature detector, an in-place module, a first station layer switch and a cable fire monitoring early-warning system server. The method comprises the following steps: step one, orderly performing initialization, denoising and normalization on sensor data; step two, initializing a feature layer, selecting a random input weight beta and an output target T to form an input matrix H; step three, processing the feature layer data in batch, performing weight iteration after the initialization; step four, making the final judgment through an algorithm; and step five, judging that the fireoccurs and giving an alarm if a fusion result is greater than a set threshold, or repeating the steps 1-4. Through the system and method disclosed by the invention, the false alarm and the failed alarm of the fire can be effectively reduced, and the accuracy of the fire prediction can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of cable fire early warning, in particular to a multi-physics fusion fire monitoring system and a method for predicting the probability of fire occurrence. Background technique [0002] Fire is a violent chemical reaction between combustibles and combustion accelerants, usually accompanied by physical and chemical phenomena of luminescence and heat generation, and aerosols, smoke, light, heat and combustion waves will be generated during the process. At present, fire detection is The course of the fire is determined through the measurement and analysis of the above parameters. [0003] Human beings have experienced more than 100 years of history in the detection and research of fire. As early as 1847, the United States developed the world's first transmission device for urban fire alarms. In 1890, the United Kingdom successfully developed a temperature-sensitive fire detector. In the next half a century, th...
