Description

Technical Field

[0001] This application relates to the field of image processing technology, and in particular to a method, apparatus and storage medium for early warning and processing of unloading port blockage. Background Technology

[0002] With the development of society, coal resources are very important to people's lives. During the mining process, due to the physical characteristics of coal seams such as thickness, hardness and structure, the integrity of coal seams is relatively strong, which may result in the formation of large-volume coal blocks during the mining process.

[0003] During the transportation of coal blocks, there is an unloading port between the coal conveyor and the transfer machine. Larger coal blocks may not be able to be unloaded from the conveyor to the transfer machine through the unloading port, resulting in blockage at the unloading port.

[0004] In related technologies, real-time monitoring and processing can be carried out manually, but the working environment is harsh, the labor cost is high, and the efficiency is low. Summary of the Invention

[0005] This application aims to address one of the technical problems in related technologies to a certain extent. Therefore, one objective of this application is to provide a method, apparatus, and storage medium for early warning and handling of unloading port blockage, thereby solving the problems of high labor costs and low efficiency caused by manual operation in related technologies. The technical solution of this application is as follows:

[0006] The first aspect of this application proposes a method for early warning and handling of unloading port blockage, comprising: obtaining a first area of ​​the passage surface of the unloading port; obtaining a second area of ​​a target cross-section of a coal block on a conveyor connected to the passage surface of the unloading port; determining, based on the second area and the first area, whether there is a risk of blockage when the coal block passes through the passage surface of the unloading port; and in response to determining that there is a risk of blockage when the coal block passes through the passage surface of the unloading port, sending a blockage warning message for the unloading port.

[0007] Furthermore, the method for early warning and handling of unloading port blockage proposed in the first aspect of this application also has the following additional features:

[0008] According to one embodiment of this application, determining whether there is a risk of blockage when the coal block passes through the unloading port based on the second area and the first area includes: determining the area ratio between the target cross-section of the coal block and the unloading port's passage surface based on the first area and the second area; and determining that there is a risk of blockage when the area ratio is greater than or equal to a set area ratio threshold.

[0009] According to one embodiment of this application, the method further includes: in response to the area ratio being greater than or equal to a set area ratio threshold, marking the coal block as a risky coal block and sending a risk warning message for the risky coal block.

[0010] According to one embodiment of this application, the method further includes: obtaining the transportation time of the coal block reaching the passage surface of the unloading port; in response to the transportation time reaching the blockage warning time threshold of the unloading port, sending the blockage warning information of the unloading port, and obtaining the passage status of the coal block on the passage surface of the unloading port; and obtaining the blockage handling measures of the unloading port based on the passage status.

[0011] According to one embodiment of this application, obtaining the transportation time of the coal block reaching the unloading port's passage surface includes: obtaining the transportation distance between the coal block and the unloading port's passage surface, and the transportation speed of the conveyor for the coal block; and obtaining the transportation time of the coal block reaching the unloading port's passage surface based on the transportation distance and the transportation speed.

[0012] According to one embodiment of this application, the step of obtaining the blockage handling measures of the unloading port based on the passage status includes: stopping the transmission of blockage warning information of the unloading port in response to the normal passage status of the coal block on the passage surface of the unloading port; determining that the unloading port is blocked in response to the abnormal passage status of the coal block on the passage surface of the unloading port; and obtaining descriptive information of the accumulation status of the coal pile at the blocked unloading port to determine the blockage handling measures of the unloading port.

[0013] According to one embodiment of this application, obtaining descriptive information about the accumulation state of the coal pile at the blocked unloading port to determine the blockage handling measures for the unloading port includes: performing frame sampling on the coal pile at the blocked unloading port to obtain candidate frames of the coal pile; obtaining target frames from the candidate frames in which overflowing coal blocks are sampled in the coal pile at the blocked unloading port; obtaining descriptive information about the accumulation state of the coal pile at the blocked unloading port based on the proportion of all target frames in all candidate frames; and determining the blockage handling measures for the unloading port based on the descriptive information.

[0014] According to one embodiment of this application, determining the blockage handling measures for the unloading port based on the description information includes: in response to the description information indicating that the coal pile's accumulation state has reached a first overflow state, determining sending a blockage alarm message for the unloading port and reducing the transport speed of the conveyor to the coal block as the blockage handling measures for the unloading port; in response to the description information indicating that the coal pile's accumulation state has reached a second overflow state, determining sending a blockage alarm message for the unloading port and stopping the operation of the conveyor as the blockage handling measures for the unloading port.

[0015] According to one embodiment of this application, obtaining the second area of ​​the target cross-section of the coal block on the conveyor connected to the unloading port's through surface includes: obtaining candidate cross-sections in which the coal block and the unloading port's through surface are parallel, and determining the candidate area of ​​the candidate cross-sections; determining the candidate area with the largest value among all candidate areas as the second area, and determining the candidate cross-section corresponding to the second area as the target cross-section of the coal block.

[0016] A second aspect of this application also proposes an early warning and handling device for unloading port blockage, comprising: a data acquisition module for acquiring real-time images of the unloading port of a transfer machine and determining a first area of ​​the passage surface of the unloading port from the real-time images; an acquisition module for acquiring a second area of ​​the cross-section of a coal block on a conveyor connected to the passage surface of the unloading port; a judgment module, conventionally used to determine whether there is a risk of blockage when the coal block passes through the passage surface of the unloading port based on the second area and the first area; and an early warning handling module for sending a blockage early warning information for the unloading port and acquiring corresponding blockage handling measures in response to determining that there is a risk of blockage when the coal block passes through the passage surface of the unloading port.

[0017] The third aspect of this application proposes a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the early warning and handling method for unloading port blockage as proposed in the first aspect above.

[0018] The method and apparatus for early warning and handling of unloading port blockage proposed in this application obtain the area ratio between the target cross-section of the coal block and the passage surface of the unloading port based on a first area and a second area. Furthermore, in scenarios where the area ratio is greater than or equal to a set area ratio threshold, it is determined that the coal block may get stuck at the unloading port when passing through the passage surface, thus causing a risk of blockage. In this application, the comparison of the first and second areas enables the identification of potential blockage risks at the unloading port, eliminating the need for manual monitoring, reducing labor costs, and mitigating the health risks to workers from harsh working environments. By marking and warning of risky coal blocks, the efficiency and accuracy of unloading port blockage early warning are improved. By sending blockage warning information, effective early warning of unloading port blockage is achieved, improving subsequent processing efficiency and optimizing the method for early warning and handling of unloading port blockage.

[0028] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Throughout, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0029] Figure 1 This is a schematic diagram of an embodiment of the pre-warning and handling method for unloading port blockage according to this application, as shown below. Figure 1 As shown, the method includes:

[0030] S101, obtain the first area of ​​the unloading port's through surface.

[0031] In practice, coal blocks can be transported using conveyors and transfer machines. There is an unloading port at the junction of the conveyor and the transfer machine. When there are large coal blocks on the conveyor, they may get stuck at the unloading port of the transfer machine and fail to pass through smoothly, which may lead to the subsequent coal flow on the conveyor accumulating at the unloading port.

[0032] Therefore, it is necessary to implement a blockage warning system for potential blockages at the unloading port.

[0033] To provide early warning of blockages at the unloading port, it is possible to determine whether the coal on the transport machine can pass through the unloading port normally by comparing the external dimensions of the coal on the transport machine with the external dimensions of the unloading port's passage surface.

[0034] In some implementations, the size parameters of the unloading port's through surface can be obtained, thereby obtaining the area of ​​the unloading port's through surface, which can be used as the first area of ​​the unloading port's through surface.

[0035] The unloading port at the intersection of the transport aircraft and the transshipment machine has a predetermined shape.

[0036] For example, in a scenario where the unloading port is rectangular, the length and width of the unloading port's passage surface can be obtained, thus yielding the first area of ​​the unloading port's passage surface.

[0037] S102, obtain the second area of ​​the cross-section of the coal block on the conveyor connected to the unloading port through surface.

[0038] In this embodiment, coal blocks need to pass through the unloading port to be unloaded from the conveyor to the transfer machine. In order to avoid large coal blocks getting stuck at the unloading port, which would cause subsequent coal flow on the conveyor to accumulate at the unloading port and cause blockage, the appearance parameters of the coal blocks on the conveyor can be monitored and identified.

[0039] Optionally, an image acquisition device can be installed at a set distance from the unloading port of the transfer machine. For example, if the image acquisition device is set to a telephoto camera with a focal length of 8mm or more, the telephoto camera can be installed at a position 3 meters away from the unloading port of the transfer machine. The telephoto camera can then be used to acquire real-time images of the coal blocks being transported on the transport machine, and the appearance parameters of the coal blocks can be monitored and identified through the real-time images.

[0040] Among them, the setting of the telephoto camera allows the image acquisition device to capture real-time images of coal blocks within a set distance range from the unloading port, thereby enabling early warning of possible blockages at the unloading port.

[0041] In some implementations, the cross-sectional size of the coal block has a certain influence on whether the coal block can pass through the unloading port normally. Therefore, the cross-sections of the coal block that are parallel to the unloading port can be obtained, and the cross-sections that affect the passage of the coal block through the unloading port can be taken as the target cross-sections.

[0042] Furthermore, the area value of the target cross-section is obtained, and this area value is identified as the second area of ​​the target cross-section.

[0043] Specifically, an image processing server can extract images of a reference object and a coal block from the real-time image, and obtain their relative proportions. Further, based on this relative proportion and the size parameters of the reference object, the size parameters of the coal block are determined, thereby obtaining the second area of ​​the target cross-section of the coal block.

[0044] For example, by setting the reference object as the scraper conveyor, the relative proportion between the display image of the coal block in the real-time image and the display image of the cell formed between two adjacent scrapers of the scraper conveyor in the real-time image can be obtained. Based on the width of the conveyor belt of the scraper conveyor and the distance between two adjacent scrapers, the length and width of the target cross-section of the coal block can be determined, thereby obtaining the second area of ​​the target cross-section.

[0045] S103, based on the second area and the first area, determine whether there is a risk of blockage when the coal block passes through the unloading port.

[0046] In this embodiment, the first area is the area of ​​the unloading port's passage surface, and the second area is the area of ​​the target cross-section where the coal block on the conveyor is parallel to the unloading port's passage surface. Therefore, by comparing the first area and the second area, the relative proportional relationship between the coal block and the unloading port's passage surface can be obtained.

[0047] Furthermore, based on the obtained relative proportions, it is determined whether the coal block can pass through the unloading port normally, thereby determining whether there is a risk of blockage when the coal block passes through the unloading port.

[0048] In the scenario where the second area is smaller than the first area, it can be understood that the area of ​​the target cross-section of the coal block is smaller than the area of ​​the unloading port's passage surface. Therefore, it can be determined that in this scenario, the coal block can pass smoothly through the unloading port's passage surface, and there is no risk of blockage at the unloading port.

[0049] Correspondingly, in the scenario where the second area is greater than or equal to the first area, it can be understood that the area of ​​the target cross-section of the coal block is greater than or equal to the area of ​​the unloading port's passage surface. Therefore, it can be determined that in this scenario, the coal block may not be able to pass through the unloading port's passage surface, and the unloading port may be blocked.

[0050] S104, in response to the determination that there is a risk of blockage when the coal block passes through the unloading port, a blockage warning message for the unloading port is sent.

[0051] In practice, in scenarios where there is a risk of blockage when determining the passage surface of the coal block through the unloading port, an early warning can be issued for such scenarios.

[0052] Optionally, the blockage warning information of the unloading port can be sent to relevant personnel through a set communication method to achieve the purpose of warning of possible blockages at the unloading port. The blockage warning information may include real-time images of coal blocks that may block the passage surface of the unloading port, real-time images of the passage surface of the unloading port, and relevant information such as the size parameters of the coal blocks.

[0053] Real-time images of the unloading port's passage surface can be obtained using image acquisition equipment installed at the unloading port where the transfer machine and the transport machine intersect.

[0054] Optionally, a short-focus camera with a focal length of 4mm or less can be installed at a distance of 3 meters from the unloading port of the transfer machine, and the real-time image of the unloading port can be acquired through the short-focus camera.

[0055] This application proposes a method for early warning and handling of unloading port blockage. It obtains a first area of ​​the passage surface of the unloading port of the transfer conveyor and a second area of ​​a target cross-section where the coal block on the conveyor is parallel to the passage surface of the unloading port. Based on the first and second areas, it determines whether there is a risk of blockage when the coal block passes through the unloading port. In scenarios where a blockage risk is determined, relevant blockage warning information for the unloading port is sent to the workers. This application achieves the identification of potential blockage risks at the unloading port by comparing the first and second areas, eliminating the need for manual monitoring, reducing labor costs, mitigating the harm to workers' health caused by harsh working environments, and improving the efficiency and accuracy of unloading port blockage warnings. By sending blockage warning information, it achieves effective early warning of unloading port blockages, improves subsequent processing efficiency, and optimizes the method for early warning and handling of unloading port blockages.

[0056] Furthermore, after determining that there may be a risk of blockage at the unloading port, it is necessary to obtain corresponding handling measures, which can be combined with... Figure 2 To understand further, Figure 2 This is a flowchart illustrating a method for warning and handling unloading port blockage according to another embodiment of this application, as shown below. Figure 2 As shown, the method includes:

[0057] S201, obtain the transportation time of the coal block reaching the unloading port.

[0058] In this embodiment, a warning can be issued regarding the potential risk of blockage at the unloading port before the coal arrives at the port, based on a set time point. Optionally, the time point for sending the unloading port blockage risk warning information can be determined according to the transportation time of the coal arriving at the unloading port.

[0059] This allows us to obtain the transport distance between the coal block and the unloading port, as well as the transport speed of the conveyor on the coal block.

[0060] In practice, the conveyor has a set number of supports. The transport distance between the coal block and the unloading port can be determined based on the number of supports between the coal block and the unloading port, as well as the set distance between two adjacent supports.

[0061] Correspondingly, the transport aircraft has a corresponding transport aircraft controller, and the currently configured transport speed of the transport aircraft can be obtained from the historical control records of the transport aircraft controller.

[0062] Furthermore, based on the transportation distance and speed, the transportation time for the coal blocks to reach the unloading port is obtained.

[0063] Optionally, the transportation time of the coal block to the unloading port can be obtained based on the quotient of transportation distance and transportation speed.

[0064] like Figure 3 As shown, real-time images of coal blocks on the conveyor can be obtained by an image acquisition device set near the unloading port, thereby obtaining the transportation distance between the coal blocks and the unloading port, and thus the transportation time of the coal blocks to the unloading port.

[0065] S202, in response to the transportation time reaching the blockage warning time threshold of the unloading port, sends the blockage warning information of the unloading port and obtains the passage status of the coal block on the passage surface of the unloading port.

[0066] In this embodiment of the application, in order to effectively handle the blockage of the unloading port, there is a set warning time threshold for the blockage warning of the unloading port. It can be understood that when the transportation time of the coal block that may cause the blockage risk of the unloading port reaches the set blockage warning time threshold, the blockage warning of the unloading port can be activated, thereby providing sufficient processing time for subsequent processing measures.

[0067] Among them, the system can send blockage warning information of the unloading port to the staff based on the set notification format. For example, the system can send the blockage warning information, including the image, size parameters and other relevant information of the coal block that may cause blockage at the unloading port, to the staff via email, SMS and other notification formats.

[0068] Furthermore, after receiving the blockage warning information, it is necessary to further monitor the unloading port. Optionally, real-time images of the unloading port can be retrieved, and when a coal block that may cause a blockage risk to the unloading port reaches the passage surface of the unloading port, its passage status on the passage surface of the unloading port can be monitored.

[0069] like Figure 3 As shown, real-time images of the unloading port can be acquired using an image acquisition device located near the unloading port, thereby enabling further monitoring and attention to the unloading port.

[0070] S203, Based on the passage status, obtain the blockage handling measures for the unloading port.

[0071] In this embodiment of the application, the current blockage status of the unloading port can be determined based on the passing status of the coal block on the unloading port's passage surface, thereby obtaining corresponding blockage handling measures.

[0072] Optionally, in response to the normal passage status of the coal block on the unloading port's passage surface, the transmission of blockage warning information at the unloading port is stopped.

[0073] In the scenario where the second area is larger than the first area, due to factors such as the transport speed of the transporter and the angle of the coal block, the coal block may have a passing surface that allows it to pass through the unloading port normally.

[0074] Furthermore, the passage status of the coal block on the unloading port can be marked as normal. In this scenario, the coal block will not cause blockage at the unloading port. Therefore, it can be determined that the current blockage warning at the unloading port is lifted, and the transmission of the blockage warning information at the unloading port can be stopped.

[0075] Optionally, in response to an abnormal passage status of the coal block on the passage surface of the unloading port, it is determined that the unloading port is blocked.

[0076] In this scenario, the state of coal blocks stuck at the unloading port and unable to reach the transfer machine can be marked as an abnormal passage status of the coal blocks at the unloading port. In this scenario, it can be determined that the coal blocks stuck at the unloading port and the coal flow subsequently transported by the conveyor to the stuck coal blocks cause blockage at the unloading port.

[0077] Furthermore, based on the relevant status information of the coal pile that is blocked at the unloading port, the corresponding blockage treatment measures can be determined.

[0078] In some implementations, descriptive information about the coal pile's accumulation status at the blocked unloading port can be obtained to determine the blocking measures for the unloading port.

[0079] In this embodiment of the application, the accumulation state of the coal pile at the unloading port can be determined by the descriptive information. The coal pile accumulation state can be determined by the parameter with a specific value, or other information with descriptive function can be used. No limitation is made here.

[0080] Optionally, descriptive information about the accumulation state of the coal pile at the unloading port after blockage can be obtained based on the state of the coal pile overflowing from the conveyor at the unloading port.

[0081] Furthermore, frame sampling is performed on the coal pile at the blocked unloading port to obtain candidate frames of the coal pile.

[0082] For example, by setting a frame sampling period of 10 seconds and sampling the coal pile at the blocked unloading port once per second, a total of 10 candidate frames can be obtained. Based on the overflow of the coal pile in the 10 candidate frames, the description information of the accumulation state of the coal pile at the blocked unloading port can be determined.

[0083] Among them, the target frame that shows overflowing coal blocks in the coal pile at the blocked unloading port can be obtained from the candidate frames.

[0084] In practice, the scenario where coal chunks fall from the conveyor after the unloading port is blocked can be marked as a coal spill scenario.

[0085] Among them, coal chunks that fall from the coal pile can be identified as overflow coal chunks, and frames that sample overflow coal chunks can be obtained from all candidate frames as target frames containing overflow coal chunks.

[0086] Furthermore, based on the proportion of all target frames in all candidate frames, descriptive information about the accumulation state of the coal pile at the unloading port after blockage is obtained.

[0087] Specifically, the number of all candidate frames and the number of all target frames can be obtained separately, and the ratio between the two can be determined as the proportion of all target frames in all candidate frames. Furthermore, based on this proportion, the description information of the accumulation state of the coal pile at the unloading port after blockage can be determined.

[0088] For example, based on the above example, if we set 7 out of 10 candidate frames to be target frames that sample overflowing coal blocks, then in this scenario, the proportion of all target frames in all candidate frames is 70%, and 70% can be determined as the description information of the accumulation state of the coal pile at the unloading port after the blockage.

[0089] For example, based on the above example, if we set all 10 candidate frames to be target frames that sampled overflowing coal blocks, then in this scenario, the proportion of all target frames in all candidate frames is 100%, and 100% can be determined as the description information of the accumulation state of the coal pile at the unloading port after the blockage.

[0090] Furthermore, based on the described information, measures to address the blockage at the unloading port are determined.

[0091] In this embodiment of the application, the stacking state of the coal pile at the unloading port after blockage can be determined by the description information. Under different stacking states, the blockage treatment measures for the unloading port may differ.

[0092] Optionally, the coal pile at the blocked unloading port can be divided into a first overflow state and a second overflow state.

[0093] In the first overflow state, the coal pile at the unloading port after blockage does not cause complete blockage of the unloading port. In this state, the coal blocks piled up near the unblocked area of ​​the unloading port may pass normally through the passage surface of the unloading port and reach the transfer machine.

[0094] Therefore, in response to the description information indicating that the coal pile has reached the first overflow state, sending a blockage alarm message at the unloading port and reducing the conveyor's transport speed of the coal block are determined as blockage handling measures at the unloading port.

[0095] In this scenario, a blockage alarm message for the unloading port can be sent to the staff based on a set notification format. The blockage alarm message may include a real-time image of the unloading port after blockage, as well as a description of the accumulation status of the coal pile at the unloading port and other relevant information.

[0096] Furthermore, a deceleration command can be sent to the transport controller corresponding to the transport machine. Based on the received deceleration command, the transport controller adjusts the transport speed of the transport machine on the coal blocks, reducing the impact of the subsequent coal flow on the coal pile accumulated at the unloading port, thereby avoiding greater blockage.

[0097] Correspondingly, in the second overflow state, the coal pile at the unloading port after being blocked has completely blocked the unloading port. In this state, in response to the description information indicating that the coal pile has reached the second overflow state, a blockage alarm message for the unloading port will be sent and the transport machine will be stopped as the blockage handling measures for the unloading port.

[0098] In this scenario, the coal pile has completely blocked the unloading port. To prevent the coal pile from worsening, a blockage alarm message can be sent to the staff based on a pre-defined notification format. The blockage alarm message can include a real-time image of the blocked unloading port, as well as a description of the coal pile's accumulation status at the unloading port and other relevant information.

[0099] Furthermore, a stop command can be sent to the transport aircraft controller corresponding to the transport aircraft, and the transport aircraft controller will control the transport aircraft to stop operating according to the received command.

[0100] For example, based on the above example, if the description of the coal pile accumulation status at the unloading port after blockage is set to 70% reaching the first overflow state, then sending a blockage alarm message to the unloading port and reducing the transport speed of the conveyor to the coal block can be used as the blockage handling measures in this scenario.

[0101] For example, based on the above example, if the description of the coal pile accumulation status at the unloading port after blockage is set to 100% reaching the second overflow state, then sending a blockage alarm message to the unloading port and stopping the operation of the transport machine can be used as the blockage handling measure in this scenario.

[0102] This application proposes a method for early warning and handling of unloading port blockage. It obtains the transportation time of coal blocks arriving at the unloading port and issues a blockage warning when the transportation time reaches a blockage warning threshold. It also monitors the passage status of coal blocks on the unloading port's passage surface. Furthermore, based on the passage status of coal blocks on the unloading port's passage surface, it obtains blockage handling measures. This application initiates unloading port blockage warnings based on transportation time, achieving the identification of potential blockage risks at the unloading port. It eliminates the need for manual monitoring, reducing labor costs and mitigating the health risks of harsh working environments for workers. It also improves the efficiency and accuracy of unloading port blockage warnings. Through control measures on the conveyor, it enhances the efficiency of handling unloading port blockages and optimizes the method for early warning and handling unloading port blockages.

[0103] In the above embodiments, the determination of congestion risk can be combined with... Figure 4 To understand further, Figure 4 This is a flowchart illustrating a method for warning and handling unloading port blockage according to another embodiment of this application, as shown below. Figure 4 As shown, the method includes:

[0104] S401, Based on the first area and the second area, determine the area ratio between the target cross-section of the coal block and the passage surface of the unloading port.

[0105] In practice, by comparing the second area and the first area, the passing status of the coal block on the unloading port can be predicted.

[0106] In scenarios where the second area is larger than the first area, the coal block may not be able to pass through the unloading port normally to reach the transfer machine, thus allowing for the assessment of the risk of blockage at the unloading port.

[0107] In this embodiment, the second area is the area of ​​the target cross-section of the coal block. The target cross-section is the cross-section with the largest area among all cross-sections on the coal block that are parallel to the unloading port's passage surface. Therefore, the second area has a certain influence on the passage state of the coal block on the unloading port's passage surface.

[0108] Furthermore, the ratio between the target cross-section and the unloading port passage surface can be obtained by calculating the ratio between the first area and the second area, and this ratio can be used as the area proportion.

[0109] S402, in response to an area percentage greater than or equal to a set area percentage threshold, determines that there is a risk of blockage when the coal block passes through the unloading port.

[0110] In this embodiment of the application, there is a corresponding area ratio threshold between the target cross-section of the coal block and the through surface of the unloading port.

[0111] Optionally, when the area ratio is greater than or equal to the set area ratio threshold, it can be determined that the coal block may not be able to pass through the unloading port normally to reach the transfer machine, and thus it can be determined that the coal block may cause blockage risk to the unloading port.

[0112] Furthermore, in this scenario, coal blocks can be monitored accordingly. In response to an area percentage greater than or equal to a set area percentage threshold, the coal block is marked as a risky coal block and a risk warning message for the risky coal block is sent.

[0113] In this embodiment of the application, in order to improve the efficiency of the unloading port blockage early warning, the coal block to which the target cross section belongs in the scenario of area proportion greater than or equal to the threshold can be marked as a risk coal block, and its relevant parameter information and real-time image can be sent to the relevant personnel as risk warning information.

[0114] The method for early warning and handling of unloading port blockage proposed in this application obtains the area ratio between the target cross-section of the coal block and the passage surface of the unloading port based on a first area and a second area. Furthermore, in scenarios where the area ratio is greater than or equal to a set area ratio threshold, it is determined that the coal block may get stuck at the unloading port when passing through the passage surface, thus causing a risk of blockage. In this application, the comparison of the first and second areas enables the identification of potential blockage risks at the unloading port, eliminating the need for manual monitoring, reducing labor costs, and mitigating the health risks to workers from harsh working environments. By marking and warning of risky coal blocks, the efficiency and accuracy of unloading port blockage early warning are improved. By sending blockage warning information, effective early warning of unloading port blockage is achieved, improving subsequent processing efficiency and optimizing the method for early warning and handling of unloading port blockage.

[0115] To better understand the above embodiments, it can be combined with Figure 5 , Figure 5 This is a flowchart illustrating a method for warning and handling unloading port blockage according to another embodiment of this application, as shown below. Figure 5 As shown, the method includes:

[0116] By using image acquisition equipment installed at the unloading port, real-time images of the conveyor and the unloading port are obtained. Based on the image comparison between the coal block and the conveyor displayed in the real-time image, and combined with the set appearance parameters of the conveyor, the appearance parameters of the coal block on the conveyor are determined.

[0117] Furthermore, the first area corresponding to the passage surface of the unloading port and the second area corresponding to the target cross-section of the coal block that is parallel to the passage surface of the unloading port are obtained. Based on the first area and the second area, the area ratio between the target cross-section of the coal block and the passage surface of the unloading port is obtained. Furthermore, in the scenario where the area ratio is greater than or equal to the set area ratio threshold, it is determined that the coal block may get stuck at the unloading port when passing through the passage surface of the unloading port, which may cause the unloading port to be blocked.

[0118] In this scenario, the coal block is marked as a high-risk coal block and a high-risk coal block warning is issued. The transportation time of the coal block to the unloading port is obtained, and when the transportation time reaches the blockage warning time threshold, a blockage warning for the unloading port is issued. The passage status of the coal block on the unloading port's passage surface is monitored. Furthermore, based on the passage status of the coal block on the unloading port's passage surface, blockage handling measures for the unloading port are obtained.

[0119] When the coal block is detected to be passing normally on the unloading port's passage surface, the blockage warning for the unloading port can be lifted.

[0120] Correspondingly, when the passage status of coal blocks on the unloading port is abnormal, it is determined that there is a blockage at the unloading port. In this scenario, the accumulation status of the coal pile at the blocked unloading port can be obtained, and then the corresponding blockage handling measures can be determined.

[0121] Optionally, when the coal pile at the blocked unloading port reaches the first overflow state, sending a blockage alarm message to the unloading port and reducing the transport speed of the conveyor to the coal block are determined as the blockage handling measures in this scenario.

[0122] Optionally, when the coal pile at the blocked unloading port reaches the second overflow state, determining to send a blockage alarm message at the unloading port and stop the transport machine is the blockage handling measure in this scenario.

[0123] The method for early warning and handling of unloading port blockage proposed in this application identifies potential blockage risks at the unloading port by comparing a first area and a second area. This eliminates the need for manual monitoring, reducing labor costs and minimizing the health risks to workers from harsh working environments. By marking and warning of risky coal blocks, the efficiency and accuracy of unloading port blockage early warning are improved. By sending blockage warning information, effective early warning of unloading port blockage is achieved, further enhancing the efficiency and accuracy of unloading port blockage early warning. Furthermore, by implementing control measures for the conveyor, the efficiency of handling unloading port blockage is improved, thus optimizing the method for early warning and handling of unloading port blockage.
