Description

Industrial boiler management system and its operation method {SYSTEM FOR MANAGING INDUSTRIAL BOLIER AND MEHTOD THEREOF}

Embodiments of the present invention relates to a system for managing an industrial boiler and an operating method thereof.

Industrial boilers can be classified into various types depending on the location of use, the shaft center of the body, the location of the combustion chamber, the type of use, whether it is moved, and the structure of the body. Industrial boilers generally used include a furnace tube boiler and a water tube boiler, and regardless of the type and structure of the industrial boiler, the performance of the boiler is greatly affected by combustion devices such as a burner. Therefore, in order to grasp the performance of the industrial boiler, it is necessary to continuously check the operation state of the combustion device.

The operation state of the combustion device such as a burner can be checked from the flame state generated through the combustion device. However, when shooting flames using commercially available photographing equipment (eg, a camera), there is a problem in compatibility with the existing boiler system, and there are many unnecessary functions for use in the field. For this reason, some incinerators are observing the combustion state in the form of putting a housing over a general CCTV and putting only the lens part of the camera into the combustion chamber. Furthermore, in the prior art, it is only used only to check the flame state by utilizing only the images taken in such a difficult way, and it does not provide an appropriate technical solution to integrate and manage the image and the entire boiler system.

According to an embodiment of the present invention, the server 150 may adjust the size of the blocks and the number of blocks according to the ratio of the image.

In step S803, the server 150 may calculate an individual flame index for each block. According to an embodiment of the present invention, the server 150 can distinguish a block of a flame area and a block of a non-flame area by analyzing the state of the flame shown in the image, and for the block divided into the flame area, according to a preset standard It is possible to calculate the individual flame index for each block. For example, the server 150 may calculate an individual flame index based on the color of the flame. Specifically, the server 150 may extract an R value from among the RGB values for each of all pixels included in one block, and the number of pixels included in one block after adding the R values of each of all pixels included in one block The divided value can be calculated as an individual flame index.

In step S805, the server 150 may calculate the total flame index based on the calculated individual flame index for each block. The total flame index is an indicator of whether the flame condition of an industrial boiler is in an appropriate state. According to an embodiment of the present invention, the server 150 may calculate the average value of the entire individual flame index as the total flame index.

In step S807, the server 150 may compare the total flame index with preset threshold values (T _max , T _min ). The first threshold value (T _max ) means the highest flame index that the industrial boiler can normally operate, and the second threshold value (T _min ) means the lowest flame index that the industrial boiler can normally operate.

If the calculated total flame index is between the first threshold value (T _max ) and the second threshold value (T _min ) (in step S807, 'Yes'), the server 150 does not perform a special operation, You can continuously monitor the flame state.

On the other hand, if the calculated total flame index is equal to or greater than the first threshold value (T _max ), or equal to or less than the second threshold value (Tmin) (in step S807, 'No'), the server 150 is A warning message to be provided to the user terminal may be generated.

Although not shown in the drawing, the server 150 may instruct the control device 170 to take appropriate measures in order to generate a warning message as well as to perform an operation for making the total flame index to a normal value.

9A to 9D are conceptual diagrams for explaining the operation of a server according to an embodiment of the present invention.

Referring to FIG. 9A , the server 150 may receive image data recording the flame state of the industrial boiler as shown in FIG. 9A from the recording device 190 .

The server 150 may divide the provided image into blocks. As shown in FIG. 9B , the server 150 may divide the image into blocks such as B ₀₁ to B ₃₉₁ .

Then, the server 150 may distinguish the block of the flame area from the block of the non-flame area, and may delete the non-flame area as shown in FIG. 9C .

The server 150 can calculate the individual flame index for the block of the flame area, calculate the total flame index based on the individual flame index, and determine whether the flame state is normal as in step S807 of FIG. can

Furthermore, when calculating the total flame index, the server 150 may calculate the total flame index by setting different weights for each block. For example, referring to FIG. 9D , the server 150 gives the highest weight to the first area 901 located in the center of the flame, the second area 903 which is the next order, the third area 905 which is the third order, and 4 The total flame index may be calculated by considering the weights in the order of the fourth area 907, which is a ranking.
