[0047] Figure 3 is a schematic structural diagram of the electronic device provided by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0048] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention with reference to the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0049] The following will describe Figures 1 - 3 a control method, device, equipment, medium and fuel cremator of the present invention.

[0050] Figure 1 It is a schematic flowchart of the control method of the fuel cremator provided by the embodiment of the present invention.

[0051] As Figure 1 shown, a control method of a fuel cremator provided by an embodiment of the present invention, the execution subject may be the control system of the fuel cremator, and the method mainly includes the following steps:

[0052] 101. Collect video images inside the furnace of the fuel cremator.

[0053] In a specific implementation process, in order to accurately understand the combustion situation in the furnace, video images inside the furnace of the fuel cremator are collected through a camera. The position of the camera can be set according to requirements to ensure that the cremation video images inside the furnace can be collected in all directions, especially the flame images of the burner should be collected. The main function of collecting video images is to understand the combustion situation inside the fuel cremator through the video images. Therefore, it is only necessary to ensure that the video images inside the furnace can be collected comprehensively and in a timely manner.

[0054] 102. Determine the real-time flame chromaticity and real-time flame length of each pixel point corresponding to the burner flame in the video image.

[0055] For a fuel cremator, the quality of the combustion in the furnace can be judged by judging the color, brightness and length of the burner flame. And in the image, the brightness is represented by gray scale, that is, a function of the base color value of the pixel point on the color image. Therefore, the color and brightness can be considered as one factor, that is, chromaticity, and then the length is considered. The two can be selected as the influencing factor set U = {real-time flame chromaticity, real-time flame length}.

[0056] Therefore, after collecting the video image, the image of the area where the burner flame is located is cut, and then each pixel point corresponding to the burner flame is analyzed and compared to determine the real-time flame chromaticity and real-time flame length of each pixel point corresponding to the burner flame.

[0057] 103. Based on the real-time flame chromaticity and real-time flame length, use a preset formula to determine the membership degree of each pixel point to obtain a membership degree matrix.

[0058] The membership degree matrix, that is, the matrix formed by the flame chromaticity and the flame length, that is, the flame chromaticity and the flame length corresponding to each pixel point are determined. For example, if 60 times are collected per minute, the membership degree matrix is composed of 60 groups of data corresponding to the real-time flame chromaticity and the real-time flame length. Thus, the real-time flame chromaticity and the real-time flame length are converted into a membership degree matrix.

[0059] 104. Multiply the membership degree matrix and the preset weight matrix to obtain a comprehensive evaluation vector.

[0060] The different combustion states corresponding to the flame chromaticity and the flame length, and the specific influence on the combustion state is also different. Therefore, the preset weight matrix can be determined according to the flame chromaticity and the flame length, that is, to determine the influence weight of the flame chromaticity and the flame length on the combustion state. For example, the preset weight matrix is A = {0.8, 0.2}, that is, the influencing factor of the flame chromaticity on the combustion state reaction is 0.8, and the flame length is 0.2.

[0061] Then multiply the membership degree matrix representing the real-time flame chromaticity and the real-time flame length obtained with the preset weight matrix, and perform a comprehensive evaluation through fuzzy transformation based on the fuzzy mathematics theory, and a comprehensive evaluation vector can be obtained, as shown in formula (1):

[0062] B 1*m = A 1*n * R n*m (1)

[0063] Among them, B 1m represents the comprehensive evaluation vector, A 1n represents the preset weight matrix, R nm represents the membership degree matrix, m represents the number of membership degrees, and n represents the index. In this embodiment, it means collecting n groups of data sets, and each group of data has m membership degrees. That is, 60 groups of data are collected within one minute, and each group of data is the flame chromaticity and the flame length, so as to reflect the combustion state of the fuel cremator within one minute through 60 groups of data.

[0064] 105. Control the oxygen supply of the fuel cremator based on the comprehensive evaluation vector.

[0065] Through the comprehensive evaluation vector, the real-time combustion situation inside the fuel cremator can be understood, whether the combustion situation is good or not. In this embodiment, the membership degree matrix includes multiple groups of membership degrees within a preset time; for example, taking 60 groups as an example, then controlling the oxygen supply of the fuel cremator based on the comprehensive evaluation vector includes: if all elements in the comprehensive evaluation vector are greater than or equal to the preset value, it is determined that the combustion situation of the fuel cremator is good; if at least one element in the comprehensive evaluation vector is less than the preset value, it is determined that the combustion situation of the fuel cremator is poor.

[0066] After there are 60 groups of data of the real-time flame chromaticity and the real-time flame length, the obtained comprehensive evaluation vector is an evaluation vector containing 60 elements. At this time, the size relationship between all elements in the comprehensive evaluation vector and the preset value can be compared. If all elements are greater than the preset value, it indicates that the combustion state is good at this time. If any at least one element among all elements is less than the preset value, it indicates that the combustion state is poor at this time.

[0067] For example, 60 groups of data are collected per minute for analysis and judgment to obtain the final comprehensive evaluation vector. If all 60 data in the comprehensive evaluation vector are greater than or equal to 0.8, it indicates that the combustion condition is good within the sampling period; if there is data less than 0.8 among the 60 data in the comprehensive evaluation vector, it indicates that the combustion condition is poor within the sampling period.

[0068] A control method for a fuel cremator provided in this embodiment includes: collecting video images inside the furnace of the fuel cremator; determining the real-time flame chromaticity and real-time flame length of each pixel point corresponding to the burner flame in the video image; based on the real-time flame chromaticity and the real-time flame length, using a preset formula to determine the membership degree of each pixel point to obtain a membership degree matrix; multiplying the membership degree matrix by a preset weight matrix to obtain a comprehensive evaluation vector; based on the comprehensive evaluation vector, controlling the oxygen supply of the fuel cremator. Since the flame chromaticity and flame length of the burner flame are collected in real time, the combustion situation inside the furnace can be remotely grasped in a timely and accurate manner, and better combustion control of the fuel cremator can be achieved.

[0069] Further, based on the above embodiment, determining the real-time flame chromaticity and real-time flame length of each pixel point corresponding to the burner flame in the video image in this embodiment includes: determining the basic color values of each pixel point in the video image; identifying the regional image corresponding to the burner flame in the video image, and extracting the flame basic color values of the corresponding pixel points in the regional image from the basic color values of each pixel point; based on the flame basic color values and a preset ratio, determining the real-time flame chromaticity and real-time flame length corresponding to the flame basic color values.

[0070] Among them, the basic color values include red basic color value, green basic color value, and blue basic color value; determining the real-time flame chromaticity corresponding to the flame basic color values based on the flame basic color values and a preset ratio includes: using a weighted conversion method to determine the preset ratios corresponding to the red basic color, green basic color value, and blue basic color value respectively; through a floating-point algorithm, multiplying the red basic color value, green basic color value, and blue basic color value by the corresponding preset ratios respectively to obtain the real-time flame chromaticity corresponding to the flame basic color values.

[0071] Specifically, after the collected video images are processed by a median filter chip and then through multimedia technology, the primary color values of each pixel point in each video image can be obtained, that is, the red primary color value R, the green primary color value G, and the blue primary color value B. Then, the area image corresponding to the burner flame is identified, and then the flame primary color values of the corresponding pixel points in the area image are extracted from the primary color values of the pixel points. The R, G, and B ratios are determined using the weighted conversion method. For example, it can be 3:6:1. Then, to determine the real-time flame chromaticity, the real-time flame chromaticity corresponding to the flame primary color value of each pixel point is obtained through a floating-point algorithm. The specific calculation method is shown in formula (2):

[0072] S = R * 0.3 + G * 0.6 + B * 0.1 (2)

[0073] The real-time flame length can be denoted as L, and the real-time flame length refers to the pixel point length value along the axial direction of the flame.

[0074] Further, on the basis of the above embodiments, before determining the membership degree of each pixel point using a preset formula based on the real-time flame chromaticity and the real-time flame length in this embodiment, it further includes: calibrating the upper limit value of the flame chromaticity and the reference value of the flame length under the balanced and stable working condition of the fuel cremator; calibrating the lower limit value of the flame chromaticity and the upper limit value of the flame length under the oxygen-deficient combustion working condition of the fuel cremator; calibrating the lower limit value of the flame length under the over-oxygen combustion working condition of the fuel cremator; determining the preset formula for calculating the membership degree based on the upper limit value of the flame chromaticity, the reference value of the flame length, the lower limit value of the flame chromaticity, the upper limit value of the flame length, and the lower limit value of the flame length.

[0075] Specifically, for the selected fuel cremator, calibration of the reference is required. For example, through the visualization system of the cremator, 10 groups of flame state values are collected when the combustion working condition of the cremator is balanced and stable. The average value of its chromaticity is taken as the upper limit value of the flame chromaticity, denoted as S 上 , and the average value of its length is taken as the reference value of the flame length, denoted as l 基 . Using the same method, 10 groups of flame state values are collected when the combustion working condition of the cremator is oxygen-deficient and the combustion is insufficient. The average value of its chromaticity is taken as the lower limit value of the flame chromaticity, denoted as S 下 , and the average value of its length is taken as the upper limit value of the flame length, denoted as l 上 . 10 groups of flame state values are collected when the combustion working condition of the cremator has excessive oxygen supply and slow combustion. The average value of its length is taken as the lower limit value of the flame length, denoted as l 下 .

[0076] Then, through the upper limit value S of the flame chromaticity 上 , the reference value l of the flame length 基 , the lower limit value S of the flame chromaticity 下 , the upper limit value l of the flame length上 and the lower limit value l of the flame length 下 , determine the preset formula for calculating the membership degree, such as formulas (3), (4), and (5).

[0077]

[0078]

[0079]

[0080] Among them, S(x) represents the real-time flame chromaticity value, L(l) represents the real-time flame length value, R represents the membership degree, s 上 represents the upper limit value of the flame chromaticity, s 下 represents the lower limit value of the flame chromaticity, s 下 represents the lower limit value of the flame length, l 上 represents the upper limit value of the flame length, l 基 represents the reference value of the flame length, x represents the real-time flame chromaticity, and l represents the real-time flame length.

[0081] For example, if data is collected 60 times per minute for analysis and judgment in actual work, the final membership degree matrix obtained is as shown in formula (6):

[0082]
