[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] Please refer to Figures 1 to 4 , Figure 1 This is a structural diagram of an online monitoring device for sintering ignition effect provided in a specific embodiment of the present invention; Figure 2 for Figure 1 Front view of the mounting box and its accessories; Figure 3 for Figure 1 Side view of the mounting box and its accessories; Figure 4 for Figure 1 Top view of the mounting box and its accessories.

[0048] This invention discloses an online monitoring device for sintering ignition effect, including a camera 1, a color value acquisition module, a color value processing module, a color value judgment module, and an early warning and control module.

[0049] The sintering trolley 8 of the sintering machine is laid with pre-treated mixed material. The sintering trolley 8 is 1.5m long and 5.5m wide. The thickness of the material layer is 800-1000mm, and the width of the material surface is 5.5m. Multiple rows of ignition burners 2 are installed above the sintering trolley 8, with each row of ignition burners 2 staggered to ensure uniform heating of the material surface. Specifically, the sintering trolley 8 has 19 ignition burners 2, all arranged in two rows.

[0050] When the ignition burner 2 is insufficiently ignited, the material surface is obviously mixed with raw material color. When the ignition burner 2 is moderate, the material surface is obviously uniform with clinker color. When the ignition burner 2 is excessively ignited, the material surface is over-melted or even connected with the shell. Based on this, the application adopts the camera 1 to collect the material surface image burned by each ignition burner 2 within a set period at a frequency of once per minute, and identifies the color value of the material surface. The set period can be one minute, but is not limited thereto. The camera 1 is fixed above the material surface to collect the material surface image at a fixed angle and distance. The camera 1 can be a high-definition camera, but is not limited thereto.

[0051] It should be noted that the material surface image collected by the camera 1 is divided into multiple equal parts to form multiple image regions, different image regions correspond to different ignition burners 2, and each image region and each ignition burner 2 can be numbered one by one, so that the ignition parameters of the ignition burners 2 with different numbers can be adjusted and controlled according to the color values of different image regions.

[0052] The color value of the material surface is preferably an HSV value, and can also be an RGB value, which is not specifically limited herein.

[0053] The input reference color value is used by the color value acquisition module to acquire three reference color components of the reference color value, which are an H reference color component, an S reference color component, and a V reference color component. The reference color value is the average value of the normal color values in the previous eight to twenty-four hours, which needs to be manually input by human intervention.

[0054] The color value acquisition module is used to acquire three actual color components of the actual color value of the material surface according to the material surface image fed back by the camera 1 within the set period, which are an H actual color component, an S actual color component, and a V actual color component.

[0055] The color value processing module is used to subtract the three actual color components from the three reference color components one by one to obtain three color component errors, which are an H color component error, an S color component error, and a V color component error. The H color component error is the absolute value of the difference between the H actual color component and the H reference color component, the S color component error is the absolute value of the difference between the S actual color component and the S reference color component, and the V color component error is the absolute value of the difference between the V actual color component and the V reference color component.

[0056] The color value judgment module is configured to judge whether at least two of the three color component errors are within a corresponding preset threshold range, and if so, the color value of the material surface is normal, and if not, the color value of the material surface is abnormal, and a warning control instruction is generated according to the current abnormal state. The preset threshold range has three, which are H color value preset threshold range, S preset threshold range and V preset threshold range, that is, as long as at least two of the H color component error, the S color component error and the V color component error are within the corresponding preset threshold range, the color value of the material surface can be judged to be normal. Specifically, the H color value preset threshold range is between 5 and 10, the S preset threshold range is between 5 and 10, and the V preset threshold range is between 30 and 40. Of course, each preset threshold range can be adjusted according to the composition of the material surface, which is not limited here. In addition, the abnormal state can be a state of excessive ignition of the burner, blockage of the burner, high ignition or excessive melting, etc. Different abnormal states correspond to different warning control instructions, different warning control instructions are used to control the warning control module to execute different warning control actions, and different warning control actions control different sintering ignition parameters.

[0057] The warning control module is configured to execute corresponding warning control actions according to the received warning control instruction, solve the corresponding abnormal state, and ensure that the color value of the material surface is within the normal range.

[0058] During monitoring, the camera 1 is used to obtain the material surface image burned by each ignition burner 2 first; then the reference color value is input, the color value acquisition module obtains three reference color components of the reference color value, and the color value acquisition module obtains three actual color components of the actual color value of the material surface according to the material surface image fed back by the camera 1 within a set period; then the color value processing module takes the absolute value by corresponding difference between the three actual color components and the three reference color components, to obtain three color component errors; then the color value judgment module judges whether at least two of the three color component errors are within a corresponding preset threshold range, and if so, the color value of the material surface is normal, and if not, the color value of the material surface is abnormal, and a warning control instruction is generated according to the current abnormal state; finally, the warning control module executes the warning control action according to the received warning control instruction.

[0059] As described above, the present application directly judges the sintering ignition effect by detecting the color of the material surface after combustion, eliminating the detection error caused by indirect detection; and when the material surface is abnormal, the corresponding warning control action is executed to make the material surface maintain normal color value for a long time, effectively improving the ignition efficiency.

If yes, the current abnormal state is the over-fired state of the burner, and a first early warning control instruction is generated. As long as the number of the abnormal color value area of the material surface is determined, the number of the corresponding ignition burner 2 can be determined, so that the number of the ignition burner 2 in the over-fired state can be accurately determined.

[0062] The first early warning control module is configured to perform a first early warning control action according to the first early warning control instruction. The first early warning control action is specifically to increase the gas pressure until the amplitude of the gas pressure is within a first preset amplitude range. The first preset amplitude range can be between 1% and 3%.

[0063] The color value judgment module further includes a second color value judgment module, and the early warning adjustment module further includes a second early warning control module.

[0064] When the color value of the material surface is abnormal, the second color value judgment module is configured to judge whether the three color component errors exceed the maximum critical value of the corresponding preset threshold range. If yes, the current abnormal state is the blocked state of the burner, and a second early warning control instruction is generated.

[0065] The second color value judgment module is configured to perform a second early warning control action according to the second early warning control instruction. The second early warning control action is specifically to clean or replace the corresponding ignition burner 2. Of course, the number of the ignition burner 2 to be cleaned or replaced can be determined according to the number of the abnormal color value area of the material surface, as long as the numbers are the same.

[0066] The color value judgment module further includes a third color value judgment module, and the early warning adjustment module further includes a third early warning control module.

[0067] When the color value of the material surface is abnormal, the third color value judgment module is configured to judge whether the H actual color component among the three actual color components is lower than a preset empirical threshold value within a preset time period. If yes, the current abnormal state is the over-fired state, and a third early warning control instruction is generated. The preset time period can be more than 15 minutes, and the preset empirical threshold value can be 17.

[0068] The third color value judgment module is configured to perform a third early warning control action according to the third early warning control instruction. The third early warning control action is specifically to decrease the gas pressure until the amplitude of the gas pressure is within a second preset amplitude range. The second preset amplitude range can be between 1% and 3%.

[0069] The color value judgment module further includes a fourth color value judgment module, and the early warning adjustment module further includes a fourth early warning control module.

[0070] When the color value of the material surface is abnormal, the fourth color value judgment module is configured to judge whether the H actual color component in the three actual color components is lower than a specified experience threshold value within a specified time period, and if so, the current abnormal state is a ignition over-melt state, and a fourth early warning control instruction is generated.
