All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
A method, apparatus and device for detecting a fire of a burner according to the present invention will be described with reference to fig. 1 to 3.
Fig. 1 is a schematic flow chart of a method for detecting fire of a burner according to an embodiment of the present invention.
As shown in fig. 1, the method for detecting the ignition of the burner provided by the embodiment of the invention mainly comprises the following steps:
101. the target image of the burner is acquired by an image acquisition device.

The target image acquired by the image acquisition device can be a color image, a black-and-white image, an infrared image and the like.
102. Based on a preset division mode, dividing the target image into grids with target quantity.
After the target image is acquired, in order to more accurately identify the target image, the target image may be selectively segmented, for example, the target image may be equally divided according to an area, and the target image may be segmented into 16 grids with the same size, and each grid is respectively identified, so that accuracy of identification can be ensured.
The position of the easy-to-catch fire point in the target image can be determined, and the target image is divided into grids with target quantity according to the position of the easy-to-catch fire point, wherein the easy-to-catch fire point refers to the point with the largest ignition frequency in the historical time or is the high-risk ignition point identified by related personnel. The grid division is carried out in a manner of easy ignition points, the specific analysis is carried out in specific conditions, the accuracy of image analysis can be ensured, and the image recognition speed is increased.
103. The brightness of each grid is respectively identified, and when the brightness is larger than the flame brightness threshold value, the presence of a fire point in the current grid is determined.
The brightness of the shot target image in the normal working state is basically kept within a certain range, and if fire occurs, the brightness of the ignition point is far greater than the brightness of the non-ignition point, so that whether the current grid has the ignition point can be determined by judging the brightness of the grid. For example, assuming that the flame luminance threshold is a, when the luminance of the grid is less than or equal to a, it indicates that there is no fire point in the grid at this time, and when the luminance of the grid is greater than a, it indicates that there is a fire point in the grid at this time. The brightness of the grid refers to the brightness corresponding to the brightest point in the grid. The brightness difference values of different grids can be compared, and when the brightness difference value is larger than a preset difference value, the fact that the ignition point exists in the grid with larger brightness is indicated.
Through the mode of brightness recognition, whether the ignition point exists can be recognized fast, the principle is simple, the recognition is accurate, and the ignition detection efficiency is improved effectively.

And determining whether a fire point exists in the target image in a brightness judging mode, if the fire point does not exist, not performing other processing, and performing image acquisition according to the image acquisition requirement. If the ignition point is determined to exist, further identification processing is needed to determine whether the ignition point detection is accurate.
At this time, it is necessary to extract the outline of the ignition point, that is, the outline of the ignition point at the boundary where the brightness is greatly changed, may be determined based on the image brightness values at the different positions, that is, the outline of the ignition point, because the brightness at the different positions of the ignition point is different, the outline of the ignition point is extracted according to the outline.

106. If the ignition point is determined to be flame, a fire extinguishing prompt is sent to the user terminal, an alarm is sent out, and if the ignition point is determined not to be flame, the ignition point is determined to be false alarm.
If the flame detection module determines that the ignition point image is flame, a fire extinguishing prompt is immediately sent to the user terminal, so that a user can extinguish the fire in time, and an alarm is sent out to ensure the safety of the burner and the safety of personnel. If the ignition point is determined not to be flame, determining that the ignition point is detected as false alarm, and continuing to keep normal ignition monitoring without alarm processing.

And when the dangerous degree is the second level, sending out an overhaul prompt to ensure the normal operation of the burner in the subsequent working process. And when the dangerous degree is three-level, the burner is controlled to stop working immediately. Therefore, the method and the device can be used for processing according to specific problems, and meet the requirement of intelligent monitoring.
Further, on the basis of the above embodiment, the present embodiment further includes: counting the firing times of different parts of the burner within a preset time period; and adjusting the monitoring frequency of different components based on the firing times, and adjusting the corresponding fire extinguishing modes.
Specifically, in order to better realize fire prevention, the firing times of different parts of the burner can be counted, the firing probability of the different parts is calculated, and then the monitoring frequency of the different parts is adjusted through the firing probability, for example, the parts with larger firing probability can be subjected to real-time image information acquisition and identification processing, and the parts with smaller firing probability can be subjected to image acquisition every five minutes. Therefore, different acquisition frequency judgment is carried out according to different firing probabilities, and the resource cost can be saved. And according to the number of fires, the corresponding fire extinguishing modes can be adjusted, including different modes of fire hydrant fire extinguishing, fire extinguisher fire extinguishing and the like. Therefore, by adjusting the fire extinguishing mode and the monitoring frequency, the fire detection can be timely realized, the fire can be timely extinguished when the fire occurs, and certain cost can be saved.
