Problems solved by technology

[0008] (2) False alarms may be generated when a naturally occurring condition is very similar to a fire
Therefore, it is difficult to use a camera with fixed spectral characteristics to meet the requirements of simultaneous detection of flame and smoke.
However, if the system adds a camera parameter control function, it will greatly increase the

Embodiment Construction

[0107] Such as figure 1 Shown is a schematic structural diagram of a fire detection system according to Embodiment 1 of the present invention. The fire detection system includes:

[0108] The dual variable camera 10 is used to obtain a video image of the detection area.

[0109] The dual variable camera 10 includes a first camera 101 working in a color or near-infrared mode and a second camera 102 working in a color or black and white mode.

[0110] The image acquisition module 11 is connected to the dual variable camera 10 and is used to convert the first video image and the second video collected from the first camera 101 and the second camera 102 into digital images, and perform filtering processing to obtain the first A time series image and a second time series image.

[0111] The fire identification module 12 is connected to the image acquisition module 11 and is used to analyze and process the first time series image and the second time series image acquired from the image...

Abstract

The invention discloses a fire disaster detection system and a method thereof. The fire disaster detection system at least comprises two changeable cameras as a first camera of colorful or near infrared mode and a second camera of colorful or white-black mode, for obtaining the video images of detected region; an image collection module connected with two changeable cameras for converting and filtering the video images collected by the two changeable cameras into digital images, to obtain time sequence images; a fire disaster recognition module connected with the image collection module for analyzing the time sequence images, to obtain flame, smoke and fire disaster occurrence probability; and an alarm module connected with the fire disaster recognition module for comparing the flame, smoke and fire disaster occurrence probability with a preset threshold value, and emitting alarm message according to the comparison result. The invention can effectively obtain the fire disaster video images under various backlight conditions, to realize early and reliable fire disaster alarm.

Description

Technical field [0001] The invention relates to fire safety monitoring technology, in particular to a fire detection system and method. Background technique [0002] With the continuous development of global industrial, commercial, and civil construction facilities, fires are also increasing year-on-year. In recent years, globalized climate changes have made fires more likely to occur, and the frequent occurrence of extreme fires has brought huge losses and troubles to mankind, especially for the global forests, which have brought huge disasters that are difficult to save. [0003] Although the current fire detection system can be used for fire detection and alarm, traditional fire detectors have the problem of response delay. For example, the heat and smoke that the detector can detect need to be larger to reach the position of the detector from the fire location. Delay, especially for fire detection in large sites such as forests, is a problem. For large sites such as forests, ...
