Problems solved by technology

In order to avoid the occurrence of fires, many institutions or companies have installed security systems. Most of the existing security systems are only equipped with image cameras. Complete monitoring, relying on human monitoring, prone to blind spots; some security systems are equipped with smoke sensors, but the false alarm rate of smoke sensors is relatively high, resulting in loss of manpower and material resources, and increasing the cost of fire prevention

Embodiment 1

[0047] Embodiment 1: see figure 1 .

[0048] A security system for fire prevention, including an image analysis subsystem 2, a temperature analysis subsystem 1, and a fire analysis chip 3; the image analysis subsystem 2 transmits image analysis result information to the fire analysis chip 3, and the temperature analysis subsystem 1 The temperature change information is transmitted to the fire analysis chip 3, and the fire analysis chip 3 combines the information of the image analysis subsystem 2 and the temperature analysis subsystem 1 to perform calculations to determine the fire situation; the security system also includes a fire external transmission device 5, and the fire situation The analysis chip 3 transmits the fire situation information to the fire situation external transmission device 5 , and the image analysis subsystem 2 synchronously transmits the image information to the fire situation external transmission device 5 . Wherein, the image analysis subsystem 2 inc...

Embodiment 2

[0054] Embodiment 2: a kind of fire detection method, comprises the following steps:

[0055] a) Real-time collection of video images in the monitoring area and temperature distribution images in the monitoring area;

[0056] In this step, a series of video images and temperature distribution images can be obtained as the calculation basis.

[0057] b) Preliminary fire judgment: extract the flame characteristic parameters from the series of frame video images collected, perform feature matching and statistical analysis on the flame characteristic parameters, and calculate the fire occurrence probability f(t) in the monitoring area;

[0058] c) Temperature analysis: extract temperature characteristic parameters from the collected temperature distribution images in the monitoring area, perform feature matching and statistical analysis on the temperature characteristic parameters, and calculate the fire occurrence probability F(t) in the monitoring area;

[0059] d) Fire judgmen...

Abstract

The invention particularly relates to a security system for preventing a fire and a fire detecting method, belonging to the technical field of fire alarm. The security system provided by the invention comprises an image analyzing subsystem, a temperature analyzing subsystem and a fire analyzing chip; the image analyzing subsystem transmits image analysis result information to the fire analyzing chip; the temperature analyzing subsystem transmits the temperature change information to the fire analyzing chip; the fire analyzing chip operates to judge the fire by combining the image analyzing subsystem and the temperature analyzing subsystem; the security system also comprise an external fire transmission device; the fire analyzing chip transmits the fire information to the external fire transmission device; and the image analyzing system transmits the image information to the external fire transmission device at the same time. According to the invention, a mode of image and temperature combined analysis is adopted, so that the fire can be effectively monitored, and the probability for misinformation of the fire can be reduced.

Description

technical field [0001] The invention belongs to the field of fire alarm technology, and in particular relates to a fire prevention security system and a fire detection method. Background technique [0002] With the development of society, people pay more and more attention to fires, because once a fire occurs, it will be accompanied by material loss; the several fires that have occurred so far have suffered huge economic damage to varying degrees. In order to avoid the occurrence of fires, many institutions or companies have installed security systems. Most of the existing security systems are only equipped with image cameras. Complete monitoring, and relying on human monitoring, is prone to blind spots; some security systems are equipped with smoke sensors, but the false alarm rate of smoke sensors is relatively high, resulting in manpower and material losses, and increasing the cost of fire prevention. Contents of the invention [0003] The object of the present inven...
