Abstract

The invention discloses a smoke detection method, a smoke detection device and a smoke detection system. The smoke detection method comprises the following steps: acquiring an image signal of an environment; carrying out contour segmentation on the image signal, and estimating a first smoke probability value of smoke contained in each segmented contour; determining a second smoke probability value that the image signal is smoke according to an automatic smoke identification algorithm; matching the image signal with a preset image signal, and determining a matched third smoke probability value; and determining whether the image signal contains smoke according to the first smoke probability value, the second smoke probability value and the third smoke probability value. According to the scheme, the technical problem that a smoke detector cannot effectively detect a fire signal is solved.

Description

technical field [0001] The invention relates to the technical field of smoke detection, in particular to a smoke detection method, a smoke detection device and a smoke detection system. Background technique [0002] Fire safety is a key area of ​​public safety. With the development of cities, large-space buildings (such as urban commercial complexes, convention and exhibition centers, terminal buildings, waiting buildings, studios, etc.) Drilling towers, oil tanks in mines, petrochemicals, and ports, airports, railways, etc.) and indoor large space places (such as factories, warehouses, etc.). However, due to the large space and complex terrain of these sites, affected by factors such as detection distance, airflow environment, and thermal barrier effects, it is difficult for contact detectors to capture fire signals in these sites in a timely and fast manner, which will lead to the traditional detection based on smoke concentration. and temperature point fire detectors wi...
