A Flame Detection, Analysis and Early Warning System

Abstract

The invention discloses a flame detection, analysis and early warning system. A plurality of video acquisition devices are arranged in a corridor at intervals, the acquisition ranges of the adjacent video acquisition devices are intersected and overlapped, each video acquisition device comprises: a camera module, whereinthe camera module comprises an infrared thermal imager and a camera, the infrared thermal imager is used for acquiring an infrared thermal image, and the camera is used for acquiring video data; a main control unit is used for analyzing the infrared thermogram after acquiring the infrared thermogram and the video data, and analyzing the video data through the first image analysis module after determining that an area with an abnormal temperature value exists on the infraredthermogram; and the first image analysis module which is used for carrying out flame feature extraction and identification on a video image in the video data, and generating flame warning condition information when it is determined that flame features exist in the video image. According to the invention, the flame characteristics in the video data can be identified to realize early warning, and the method has the characteristic of high safety.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a flame detection, analysis and early warning system. Background technique [0002] Fire is extremely destructive, so people attach great importance to fire prevention, and invest a lot of manpower and material resources in the research and development of fire prevention, detection and elimination technologies. [0003] Among them, in buildings such as hotels and offices, fire monitoring is usually done by installing smoke alarms in the corridors, collecting smoke through the smoke alarms, and then sending out warning signals when smoke is found, and then detecting the fire source. Do extinguish. [0004] However, the smoke alarm can only be detected after the fire point of the flame has a certain scale and the material in the corridor is burned, which often causes the fire source to be extinguished in time. In the existing flame warning system, there are people in the ...

[0004] However, the smoke alarm can only be detected after the fire point of the flame has a certain scale and the material in the corridor is burned, which often causes the fire source to be extinguished in time

In the existing flame warning system, there are people in the corridor who throw unextinguished cigarette butts into the trash can, and such small fire safety hazards cannot be early warned. Therefore, there are certain improvements in safety.
