Description

Technical Field

[0001] The present invention relates to the field of information transmission, and particularly to a method for spraying mortar on the brick gas ducts in the basement of a coke oven. Background Art

[0002] The quality of the refractory materials in the coke oven, the fullness of the mortar during masonry construction, the protection of the finished products during the construction process, the thermal expansion of the furnace body during the coke oven baking period, and the temperature changes during the production process may all cause the mortar at the brick joints of the brick gas ducts to fall off, crack, and the pipe bricks to be damaged. For different situations, spraying mortar on the brick gas ducts can effectively seal the leakage points. Currently, the common treatment methods in the coking industry are the spraying method and the full-flow method.

[0003] The existing methods for spraying mortar on the brick gas ducts in the basement of a coke oven often have the following technical problems:

[0004] First, when the central control room receives the gas leakage alarm information, it is necessary to first dispatch workers to the gas leakage point to check the specific situation, and generate a spraying mortar leak repair plan based on the gas leakage situation feedback by the workers. The whole process takes a long time, resulting in low efficiency of spraying mortar leak repair. At the same time, if there are a large number of brick gas ducts, it is necessary to carry out spraying mortar leak repair one by one, consuming a long time;

[0005] Second, most of the existing spraying mortar leak repairs adopt a unified plan for spraying mortar leak repair, with poor spraying effect and easy waste of spraying materials;

[0006] Third, during the process of spraying mortar work, it is impossible to monitor the spraying situation in real time, resulting in the inability to stop the operation in time when the spraying effect is poor, causing waste of spraying materials, or usually disposing of the remaining spraying materials after spraying mortar is completed, which also causes waste of spraying materials. Summary of the Invention

[0007] This part of the present invention content is used to briefly introduce the concepts, which will be described in detail in the following specific implementation part. This part of the present invention content is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0008] The present invention proposes a method for spraying mortar on the brick gas ducts in the basement of a coke oven to solve one or more of the technical problems mentioned in the above background art part.

[0009] The present invention provides a method for spraying mortar on the brick gas ducts in the basement of a coke oven, including:

[0010] Determine the distribution of leakage positions of each brick gas duct through pre-laid gas detection alarm devices. The distribution of leakage positions includes the number of gas leakage positions and the position information of each gas leakage position;

[0011] Query the location information of each gas leakage location in the location information of multiple gas leakage locations in the preset camera information list to obtain the camera identifier that matches the location information of the gas leakage location as the matching camera identifier, and obtain a group of matching camera identifiers; obtain the brick gas duct images collected by the cameras represented by each matching camera identifier in the group of matching camera identifiers as the gas leakage location images, and form a group of gas leakage location images; determine the gas leakage location characteristics corresponding to each gas leakage location image according to the group of gas leakage location images; the gas leakage location characteristics include the height of the gas leakage location, the area of the gas leakage location, and the depth of the gas leakage location.

[0012] For each brick gas duct, determine the average height and average depth of the corresponding multiple gas leakage locations; if the number of gas leakage locations is greater than the preset number or the average depth is greater than the preset depth, add the corresponding brick gas duct to the first brick gas duct group, and use the inner pipe grouting method to grout and leak repair for the brick gas ducts in the first brick gas duct group; if the number of gas leakage locations is less than the preset number and the average depth is less than the preset depth, add the corresponding brick gas duct to the second brick gas duct group, and use the ordinary grouting method to grout and leak repair for the brick gas ducts in the second brick gas duct group.

[0013] When using the ordinary grouting method to grout and leak repair, the grouting and leak repair plan is determined by the following method:

[0014] According to the area and depth of the gas leakage location corresponding to each gas leakage location, determine the amount of slurry to be injected into each gas leakage location; for the amount of slurry to be injected into each gas leakage location, match it in the preset grouting equipment information list, and screen out multiple grouting equipment that match the amount of slurry to be injected into each gas leakage location as the preselected grouting equipment, and obtain a group of preselected grouting equipment corresponding to each gas leakage location; among them, the grouting equipment information list includes multiple grouting equipment names, the capacity corresponding to each grouting equipment, and the status corresponding to each grouting equipment.

[0015] Subtract the capacity corresponding to each preselected grouting equipment in the group of preselected grouting equipment from the amount of slurry to be injected into each gas leakage location to obtain the grouting amount difference, divide the grouting amount difference by the amount of slurry to be injected to obtain the grouting deviation corresponding to each preselected grouting equipment, compare the grouting deviation corresponding to each preselected grouting equipment with the preset grouting deviation, if the grouting deviation corresponding to the preselected grouting equipment is less than the preset grouting deviation, then use the preselected grouting equipment as the matching grouting equipment, and obtain multiple matching grouting equipment corresponding to each gas leakage location; use the matching grouting equipment with the status of idle status in the multiple matching grouting equipment as the selected grouting equipment; use the selected grouting equipment to execute the grouting and leak repair plan.

[0016] Optionally, the method for spraying mortar on the brick gas ducts in the coke oven basement of the present invention further includes:

[0017] Adjust the first group of brick gas ducts and the second group of brick gas ducts in the following manner:

[0018] Determine the high leakage positions where the vertical height is greater than or equal to the preset height, and determine the low leakage positions where the vertical height is less than the preset height. Count the proportion of high leakage positions corresponding to each brick gas duct in the first group of brick gas ducts;

[0019] If the proportion of high leakage positions is greater than the preset proportion, move the corresponding brick gas duct out of the first group of brick gas ducts and add it to the second group of brick gas ducts.

[0020] Optionally, the preset spraying deviation is determined through the following steps:

[0021] Obtain multiple historical spraying records. Each historical spraying record includes the position information of the gas leakage position, the name of the selected spraying equipment, and the remaining mortar volume. Query in the spraying equipment information list for the name of the selected spraying equipment in each historical spraying record to obtain the capacity corresponding to each selected spraying equipment;

[0022] Subtract the capacity corresponding to each selected spraying equipment from the corresponding remaining mortar volume to obtain the actual mortar volume sprayed into each gas leakage position. Divide the remaining mortar volume by the actual mortar volume sprayed into the corresponding gas leakage position to obtain multiple actual spraying deviations. Calculate the average value of the multiple actual spraying deviations to obtain the preset spraying deviation.

[0023] Optionally, determining the mortar volume to be sprayed according to the area and depth of the gas leakage position includes:

[0024] If the spraying method is the inner inserted pipe spraying method, determine the mortar volume to be sprayed according to the area and depth of the gas leakage position.

[0025] Optionally, the method for spraying mortar on the brick gas ducts in the coke oven basement of the present invention further includes:

[0026] Select the brick gas duct with the largest number of gas leakage positions from the first group of brick gas ducts as the first test brick gas duct, and select the brick gas duct with the largest average depth from the second group of brick gas ducts as the second test brick gas duct;

[0027] Configure a first mortar mixing ratio plan for the first test brick gas duct, and configure a second mortar mixing ratio plan for the second test brick gas duct;

[0028] Perform grouting leak repair tests on the first test brick gas passage and the second test brick gas passage respectively to obtain the first test result corresponding to the first test brick gas passage and the second test result corresponding to the second test brick gas passage;

[0029] According to the first test result and the second test result, obtain the first test result score and the second test result score; perform ratio operations on the first test result score and the second test result score respectively with the preset standard test result score to obtain the first test adjustment coefficient and the second test adjustment coefficient;

[0030] According to the first test adjustment coefficient and the second test adjustment coefficient, adjust the first slurry mixing ratio plan and the second slurry mixing ratio plan to obtain the first standard slurry mixing ratio plan and the second standard slurry mixing ratio plan.

[0031] The present invention has the following beneficial effects:

[0032] 1. It shortens the time to determine the specific situation of the leakage location and improves the grouting leak repair efficiency. Specifically, through the collaborative effect of the gas detection alarm and the camera, the time to determine the specific situation of the leakage location is shortened and the grouting leak repair efficiency is improved. In practice, when the control room receives the alarm information from the gas detection alarm, workers still need to be dispatched to the alarm location to verify the specific situation of the leakage location, and then feedback the specific situation of the leakage location to the control room, and then determine the specific leak repair plan. Therefore, through the collaborative effect of the gas detection alarm and the camera, the location information and characteristics of the gas leakage location are determined, shortening the time to determine the specific situation of the leakage location and improving the grouting leak repair efficiency. In addition, different grouting methods are adopted according to the characteristics of different gas leakage locations, improving the grouting leak repair efficiency.

[0033] 2. It improves the grouting leak repair effect and reduces the waste of grouting materials. Specifically, by adjusting the brick gas passage group and the slurry mixing ratio plan, the grouting leak repair effect is improved. In practice, the commonly used grouting leak repair method is to directly spray the leakage location with a grouting device, and the deeper parts of the cracks may not be sprayed in place, thus affecting the grouting leak repair effect. Therefore, by adjusting the brick gas passage group, a suitable grouting method is configured for different brick gas passages, and through the grouting leak repair test, the standard slurry mixing ratio plan is determined, thereby improving the grouting leak repair effect. In addition, by determining the preset grouting deviation, the waste of grouting materials is reduced.

[0034] 3. Reduced waste of spraying materials. Specifically, by interacting with the user terminal, the waste of spraying materials is reduced. In practice, it is impossible to monitor the spraying work in real time, resulting in the inability to stop the work in time when the spraying effect is poor, causing waste of spraying materials. Therefore, by interacting with the user terminal, a stop work instruction is issued to the spraying equipment with unqualified spraying effect or unfinished spraying work on time, thus avoiding waste of spraying materials. In addition, after the spraying work is completed, the next virtual leakage position is selected according to the remaining slurry volume, further reducing the waste of spraying materials.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] As Figure 1 shown, a flowchart of a method for spraying mortar on the brick gas ducts in the coke oven basement according to the present invention is shown, which specifically includes the following steps:

[0044] Step 101, determine the distribution of leakage positions of each brick gas duct through a pre-installed gas detection alarm. The distribution of leakage positions includes the number of gas leakage positions and the position information of each gas leakage position.

[0045] In some embodiments, the execution entity may be a background server. A plurality of gas detection alarms are installed on the brick gas ducts in the coke oven basement, and the gas detection alarms are used to detect the gas concentration outside the brick gas ducts.

[0046] In practice, the execution entity communicates with a plurality of gas detection alarms through various communication methods. At the same time, the execution entity locally stores a gas detection alarm information list, where the gas detection alarm information list includes a plurality of gas detection alarm identifiers, the position information corresponding to each gas detection alarm, and the position information corresponding to each gas detection alarm is the specific installation position of the gas detection alarm on the brick gas duct. On this basis, the execution entity receives a plurality of gas leakage information sent by the gas detection alarms, counts the number of received gas leakage information as the number of gas leakage positions, and uses the position information of the gas detection alarm that sends the gas leakage information as the position information of each gas leakage position.

[0047] Step 102, query for each gas leakage position information in the position information of a plurality of gas leakage positions in a preset camera information list to obtain a camera identifier that matches the position information of the gas leakage position as a matching camera identifier, and obtain a matching camera identifier group; where the camera information list includes a plurality of camera identifiers and the position information corresponding to each camera; obtain the brick gas duct images collected by the cameras represented by each matching camera identifier in the matching camera identifier group as gas leakage position images, and form a gas leakage position image group; determine the gas leakage position characteristics corresponding to each gas leakage position image according to the gas leakage position image group, and the gas leakage position characteristics include the height of the gas leakage position, the area of the gas leakage position, and the depth of the gas leakage position.

[0048] In some embodiments, a plurality of cameras are installed in the brick gas ducts. Each camera corresponds to a camera identifier. The execution entity is communicatively connected to the cameras through various communication means. Meanwhile, the execution entity locally stores a preset camera information list, where the camera information list includes a plurality of camera identifiers and the position information corresponding to each camera. On this basis, the position information of each gas leakage location is matched with the position information corresponding to each camera in the preset camera information list to obtain the position information of the camera that matches the position information of the gas leakage location, and the corresponding camera identifier is obtained as the matching camera identifier, thereby obtaining a group of matching camera identifiers.

[0049] In practice, the execution entity receives the brick gas duct images collected by each camera, and selects the brick gas duct images collected by the cameras represented by the respective matching camera identifiers in the group of matching camera identifiers as the gas leakage location images to form a group of gas leakage location images.

[0050] In practice, the camera has an image automatic recognition function. During the process of collecting the brick gas duct images, the images are automatically recognized to obtain the gas leakage location features, where the gas leakage location features include the height of the gas leakage location, the area of the gas leakage location, and the depth of the gas leakage location.

[0051] Step 103: For each brick gas duct, determine the average height and average depth of the corresponding multiple gas leakage locations; if the number of gas leakage locations is greater than the preset number or the average depth is greater than the preset depth, add the corresponding brick gas duct to the first brick gas duct group, and use the inner inserted pipe grouting method to perform grouting leak repair on the brick gas ducts in the first brick gas duct group; if the number of gas leakage locations is less than the preset number and the average depth is less than the preset depth, add the corresponding brick gas duct to the second brick gas duct group, and use the ordinary grouting method to perform grouting leak repair on the brick gas ducts in the second brick gas duct group.

[0052] In some embodiments, there are multiple brick gas channels in the coke oven basement. Determine which brick gas channel each gas leakage location belongs to. For each brick gas channel, calculate the average height and average depth of the corresponding multiple gas leakage locations. If the number of gas leakage locations is greater than a preset number or the average depth is greater than a preset depth, add the corresponding brick gas channel to the first group of brick gas channels. The preset number and preset depth are determined by manual experience. The grouting method used in the first group of brick gas channels is the internal inserted pipe grouting method. If the number of gas leakage locations is less than the preset number and the average depth is less than the preset depth, add the corresponding brick gas channel to the second group of brick gas channels, and use the ordinary grouting method for grouting and leak repair for the brick gas channels in the second group of brick gas channels. If the number of gas leakage locations is large, when using the ordinary grouting method, it is necessary to grout each gas leakage location in turn, and the working time is long. Therefore, the internal inserted pipe grouting method is used. If the average depth is large, when using the ordinary grouting method, the slurry cannot be sprayed into the deep part of the gap. Therefore, the internal inserted pipe grouting method is used.

[0053] Step 104, when using the ordinary grouting method for grouting and leak repair, the grouting and leak repair plan is determined by the following method:

[0054] Sub-step one, determine the amount of slurry to be sprayed into each gas leakage location according to the area and depth of the gas leakage location corresponding to each gas leakage location; for the amount of slurry to be sprayed into each gas leakage location, match it in the preset list of grouting equipment information, and screen out multiple grouting equipment that match the amount of slurry to be sprayed into each gas leakage location as the preselected grouting equipment, and obtain the preselected grouting equipment group corresponding to each gas leakage location; among them, the list of grouting equipment information includes multiple grouting equipment names, the capacity corresponding to each grouting equipment, and the status corresponding to each grouting equipment.

[0055] In some embodiments, the execution entity locally stores a preset list of grouting equipment information. Among them, the list of grouting equipment information includes multiple grouting equipment names, the capacity corresponding to each grouting equipment, and the status corresponding to each grouting equipment. The capacity corresponding to each grouting equipment can be the amount of slurry that each grouting equipment can carry, and the status corresponding to each grouting equipment can be the idle state and the use state. On this basis, multiply the area and depth of the gas leakage location of each gas leakage location to obtain the volume of each gas leakage location, and use the volume of each gas leakage location as the amount of slurry to be sprayed into each gas leakage location. Compare the amount of slurry to be sprayed into each gas leakage location with the capacity corresponding to each grouting equipment in the preset list of grouting equipment information, and use the grouting equipment with the capacity corresponding to the grouting equipment greater than the amount of slurry to be sprayed into each gas leakage location as the preselected grouting equipment, and obtain the preselected grouting equipment group corresponding to each gas leakage location.

[0056] Sub-step 2: Subtract the capacity of each preselected spraying device in the preselected spraying device group from the amount of slurry to be injected at each gas leakage location to obtain a spraying volume difference. Divide the spraying volume difference by the amount of slurry to be injected to obtain the spraying deviation corresponding to each preselected spraying device. Compare the spraying deviation corresponding to each preselected spraying device with the preset spraying deviation. If the spraying deviation corresponding to the preselected spraying device is less than the preset spraying deviation, then regard the preselected spraying device as a matching spraying device to obtain multiple matching spraying devices corresponding to each gas leakage location; regard the matching spraying devices with an idle state among the multiple matching spraying devices as the selected spraying devices; use the selected spraying devices to execute the spraying leak repair plan.

[0057] In some embodiments, the preset spraying deviation is determined according to manual experience and can be 10%. On this basis, regard the preselected spraying devices with a spraying deviation less than the preset spraying deviation as the matching spraying devices to obtain multiple matching spraying devices corresponding to each gas leakage location, and query in the spraying device information list for each matching spraying device to screen out the matching spraying devices with an idle state as the selected spraying devices, and the worker uses the selected spraying devices to execute the spraying leak repair plan. Among them, the spraying leak repair plan is a plan for using the selected spraying devices to perform spraying leak repair.

[0058] In these embodiments, the time for determining the specific situation of the leakage location is shortened, and the spraying leak repair efficiency is improved. Specifically, through the cooperative action of the gas detection alarm and the camera, the time for determining the specific situation of the leakage location is shortened, and the spraying leak repair efficiency is improved. In practice, when the control room receives the alarm information from the gas detection alarm, it is still necessary to dispatch workers to the alarm location to verify the specific situation of the leakage location, and then feedback the specific situation of the leakage location to the control room, and then determine the specific leak repair plan. Therefore, through the cooperative action of the gas detection alarm and the camera, the location information and characteristics of the gas leakage location are determined, the time for determining the specific situation of the leakage location is shortened, and the spraying leak repair efficiency is improved. In addition, different spraying methods are adopted according to the characteristics of different gas leakage locations, which improves the spraying leak repair efficiency.

[0059] In some embodiments, in order to further solve Technical Problem 2 described in the background art part, that is, "most of the existing spraying leak repairs adopt a unified plan for spraying leak repair, resulting in poor spraying effect and easy waste of spraying materials", in some embodiments of the present invention, the first brick gas duct group and the second brick gas duct group are adjusted in the following manner:

[0060] Step 1: Determine the gas leakage positions with a vertical height greater than or equal to the preset height as the high-position leakage positions, and determine the gas leakage positions with a vertical height less than the preset height as the low-position leakage positions. Count the proportion of high-position leakage positions corresponding to each brick gas duct in the first brick gas duct group.

[0061] In some embodiments, compare the vertical height of each gas leakage position with the preset height. If the vertical height is greater than or equal to the preset height, determine the corresponding gas leakage position as the high-position leakage position, and determine the gas leakage position with a vertical height less than the preset height as the low-position leakage position. Herein, the preset height can be the average height of multiple gas leakage positions in each brick gas duct. Count the number of high-position leakage positions in each brick gas duct, and divide the number of high-position leakage positions by the number of gas leakage positions to obtain the proportion of high-position leakage positions corresponding to each brick gas duct. Count the proportion of high-position leakage positions corresponding to each brick gas duct in the first brick gas duct group.

[0062] Step 2: If the proportion of high-position leakage positions is greater than the preset proportion, remove the corresponding brick gas duct from the first brick gas duct group and add it to the second brick gas duct group.

[0063] In some embodiments, compare the proportion of high-position leakage positions corresponding to each brick gas duct in the first brick gas duct group with the preset proportion. If the proportion of high-position leakage positions corresponding to the brick gas duct in the first brick gas duct group is greater than the preset proportion, remove the corresponding brick gas duct from the first brick gas duct group and add it to the second brick gas duct group.

[0064] Among them, the preset spraying deviation is determined through the following steps:

[0065] Step 1: Obtain multiple historical spraying records. Each historical spraying record includes the position information of the gas leakage position, the name of the selected spraying device, and the remaining slurry volume. Query the name of the selected spraying device in each historical spraying record in the spraying device information list to obtain the capacity corresponding to each selected spraying device.

[0066] In some embodiments, the execution entity locally stores multiple historical spraying records. Each historical spraying record includes the position information of the gas leakage position, the name of the selected spraying device, and the remaining slurry volume. Herein, the remaining slurry volume is the slurry remaining in the spraying device after the spraying leak repair is completed. On this basis, obtain multiple historical spraying records, and query the name of the selected spraying device in each historical spraying record in the spraying device information list to obtain the capacity corresponding to each selected spraying device.

[0067] Step 2: Subtract the capacity corresponding to each selected spraying device from the corresponding remaining mud volume to obtain the actual mud volume sprayed into each gas leakage location. Divide the remaining mud volume by the actual mud volume sprayed into the corresponding gas leakage location to obtain multiple actual spraying deviations. Calculate the average value of the multiple actual spraying deviations to obtain the preset spraying deviation.

[0068] In some embodiments, there is a deviation between the actual mud volume sprayed into each gas leakage location and the mud volume that needs to be sprayed into each gas leakage location. By calculating the actual spraying deviations corresponding to multiple historical spraying records and calculating the average value of the multiple actual spraying deviations, the preset spraying deviation is obtained, thereby reducing the waste of spraying materials.

[0069] Among them, determining the mud volume that needs to be sprayed according to the area and depth of the gas leakage location includes the following steps:

[0070] Step 1: If the spraying method is the inner inserted pipe spraying method, determine the mud volume that needs to be sprayed according to the area and depth of the gas leakage location.

[0071] In some embodiments, if the spraying method used for the gas leakage location is the inner inserted pipe spraying method, multiply the area of the gas leakage location by the depth of the gas leakage location to obtain the mud volume that needs to be sprayed.

[0072] Among them, the spraying method for the brick gas duct in the coke oven basement of the present invention further includes the following steps:

[0073] Step 1: Select the brick gas duct with the largest number of gas leakage locations from the first group of brick gas ducts as the first test brick gas duct, and select the brick gas duct with the largest average depth from the second group of brick gas ducts as the second test brick gas duct.

[0074] In some embodiments, compare the number of gas leakage locations of each brick gas duct in the first group of brick gas ducts, and select the brick gas duct with the largest number of gas leakage locations as the first test brick gas duct. Compare the average depth of each brick gas duct in the second group of brick gas ducts, and select the brick gas duct with the largest average depth as the second test brick gas duct.

[0075] Step 2: Configure the first mud mixing ratio plan for the first test brick gas duct and configure the second mud mixing ratio plan for the second test brick gas duct.

[0076] In some embodiments, multiple historical spraying and leak - filling records are locally stored in the execution entity. The historical spraying and leak - filling records include the identification of the brick gas duct, the number of corresponding gas leakage positions, the average depth of the corresponding multiple gas leakage positions, and the slurry mixing ratio scheme adopted. On this basis, the multiple historical spraying and leak - filling records are compared. The slurry mixing ratio scheme adopted for the brick gas duct with the largest number of gas leakage positions in the historical spraying and leak - filling records is selected as the first slurry mixing ratio scheme. The slurry mixing ratio scheme adopted for the brick gas duct with the largest average depth of the brick gas duct in the historical spraying records is selected as the second slurry mixing ratio scheme. The first slurry mixing ratio scheme is configured for the first test brick gas duct, and the second slurry mixing ratio scheme is configured for the second test brick gas duct.

[0077] Step three: Perform spraying and leak - filling tests on the first test brick gas duct and the second test brick gas duct respectively to obtain the first test result corresponding to the first test brick gas duct and the second test result corresponding to the second test brick gas duct.

[0078] In some embodiments, spraying and leak - filling tests are performed on the first test brick gas duct and the second test brick gas duct respectively to obtain the first test result corresponding to the first test brick gas duct and the second test result corresponding to the second test brick gas duct. Among them, the first test result can be the spraying and leak - filling depth and the number of leak - filled gas leakage positions, and the second test result can be the spraying area and the spraying thickness.

[0079] Step four: According to the first test result and the second test result, obtain the first test result score and the second test result score; perform ratio operations on the first test result score and the second test result score respectively with the preset standard test result score to obtain the first test adjustment coefficient and the second test adjustment coefficient.

[0080] In some embodiments, the preset standard test result score can be 100 points. The first test result and the second test result are scored respectively, and the first test result score and the second test result score obtained are used to perform ratio operations with the preset standard test result score respectively to obtain the first test adjustment coefficient and the second test adjustment coefficient.

[0081] Step five: According to the first test adjustment coefficient and the second test adjustment coefficient, adjust the first slurry mixing ratio scheme and the second slurry mixing ratio scheme to obtain the first standard slurry mixing ratio scheme and the second standard slurry mixing ratio scheme.

[0082] In some embodiments, multiply the first test adjustment coefficient by the amount of slurry in the first slurry mixing ratio scheme to obtain the first standard slurry mixing ratio scheme, and multiply the second test adjustment coefficient by the amount of slurry in the second slurry mixing ratio scheme to obtain the second standard slurry mixing ratio scheme.

[0083] In these embodiments, the effect of shotcreting for leak repair is improved, and the waste of shotcreting materials is reduced. Specifically, by adjusting the brick gas duct group and the mud mixing ratio scheme, the effect of shotcreting for leak repair is improved. In practice, the commonly used method for shotcreting leak repair is to directly spray the leakage position with a shotcreting device. In some places with deeper cracks, the spraying may not reach the position, thus affecting the effect of shotcreting for leak repair. Therefore, by adjusting the brick gas duct group, appropriate shotcreting methods are configured for different brick gas ducts. Through shotcreting leak repair tests, the standard mud mixing ratio scheme is determined, thereby improving the effect of shotcreting for leak repair. In addition, by determining the preset shotcreting deviation, the waste of shotcreting materials is reduced.

[0084] In some embodiments, in order to further solve Technical Problem 3 described in the background art section, that is, "during the shotcreting operation, the shotcreting situation cannot be monitored in real time, resulting in the inability to stop the operation in time when the shotcreting effect is poor, causing waste of shotcreting materials, or usually the remaining shotcreting materials are disposed of after shotcreting is completed, which also causes waste of shotcreting materials", in some embodiments of the present invention, the following steps are further included:

[0085] Step 1: Add multiple gas leakage positions with the shotcreting method of inner inserted pipe shotcreting to the target gas leakage position group. According to the position information of each gas leakage position in the target gas leakage position group, map each gas leakage position to the three-dimensional model of the brick gas duct in the coke oven basement to obtain the marked three-dimensional model of the brick gas duct, where each gas leakage position corresponds to a virtual leakage position.

[0086] In some embodiments, the three-dimensional model of the brick gas duct in the coke oven basement is locally deployed on the execution entity, and at the same time, the position information of multiple gas leakage positions and the corresponding shotcreting methods are stored. On this basis, obtain multiple gas leakage positions with the shotcreting method of inner inserted pipe shotcreting, form the target gas leakage position group, map the position information of each gas leakage position in the target gas leakage position group to the three-dimensional model of the brick gas duct in the coke oven basement, obtain the corresponding position of each gas leakage position in the model as the virtual leakage position, and mark it in the model for the virtual leakage position to obtain the marked three-dimensional model of the brick gas duct.

[0087] Step 2: Display the marked three-dimensional model of the brick gas duct through the user terminal, and configure an information input control for each virtual leakage position. The information input control includes a status selection sub-control and a post-shotcreting image input sub-control. The status selection sub-control is used to receive the status information input by the user; when the status information of the target virtual leakage position becomes "shotcreting completed", display the post-shotcreting image input sub-control corresponding to the target virtual leakage position through the user terminal to enable the user to input the post-shotcreting image; generate shotcreting effect evaluation information according to the post-shotcreting image input by the user.

[0088] In some embodiments, the execution entity communicates and connects with the user terminal through various communication methods. Among them, the user terminal can be a computer or a mobile phone. On this basis, a three-dimensional model of the marked post-brick gas duct is displayed on the user terminal, and an information input control is configured at each virtual leakage position. The information input control includes a status selection sub-control and a post-spraying image input sub-control. The status selection sub-control is used to receive the status information input by the user. The status information is the information indicating the spraying working status, which can be spraying or spraying completed. The post-spraying image input sub-control is used to receive the post-spraying image input by the user. In practice, when the status information of the target virtual leakage position becomes spraying completed, the execution entity displays the post-spraying image input sub-control corresponding to the target virtual leakage position through the user terminal, and the user inputs the post-spraying image through the post-spraying image input sub-control. At the same time, a spraying effect evaluation model is locally deployed on the execution entity, which is used to evaluate the effect of the post-spraying image and generate spraying effect evaluation information. The spraying effect evaluation information can indicate that the spraying effect meets the standard or does not meet the standard.

[0089] Step 3, if the post-spraying image input by the user or the spraying effect evaluation information indicating that the spraying effect does not meet the standard is not received within the preset duration, control the selected spraying device to stop spraying; if the spraying effect evaluation information indicates that the spraying effect meets the standard, determine the next virtual leakage position according to the current position distance and the remaining slurry volume of the selected spraying device.

[0090] In some embodiments, the preset duration is determined by manual experience. On this basis, if the execution entity does not receive the post-spraying image input by the user or the spraying effect evaluation information indicating that the spraying effect does not meet the standard within the preset duration, send a stop spraying instruction to make the selected spraying device stop spraying; if the spraying effect evaluation information indicates that the spraying effect meets the standard, compare the remaining slurry volume of the selected spraying device with the slurry volume to be sprayed into the gas leakage positions that have not been sprayed, select multiple virtual leakage positions corresponding to the remaining slurry volume of the selected spraying device being greater than the slurry volume to be sprayed into the gas leakage positions that have not been sprayed, and compare the position information of the multiple virtual leakage positions with the position information of the current position, and select the virtual leakage position with the smallest distance from the current position as the next virtual leakage position.

[0091] In these embodiments, the waste of spraying materials is reduced. Specifically, by interacting with the user terminal, the waste of spraying materials is reduced. In practice, the spraying work cannot be monitored in real time, resulting in the inability to stop the work in time when the spraying effect is poor, causing waste of spraying materials. Therefore, by interacting with the user terminal, a stop work instruction is issued to the spraying equipment whose spraying effect does not meet the standard or whose spraying work is not completed on time, thus avoiding the waste of spraying materials. In addition, after the spraying work is completed, the next virtual leakage position is selected according to the remaining amount of slurry, further reducing the waste of spraying materials.
