[0046] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0047] <System Implementation>

[0048] Figure 1 This is a schematic diagram of the structural composition of a blast furnace tuyeres imaging intelligent monitoring system capable of applying an image processing method according to one embodiment. (See diagram for example.) Figure 1 As shown, the system includes at least one camera cluster 100, a power supply unit 200, and a server 300. The system can be applied to blast furnace production scenarios.

[0049] The power supply unit 200 is electrically connected to at least one group of camera clusters 100.

[0050] The server 300 is communicatively connected to at least one group of camera clusters 100 and a power supply device 200. The server 300 is configured to output a first power supply command to the power supply device 200 in response to a user-output image acquisition command, and to generate a simulated image based on a preset point cloud model and the sampled image when it receives a sampled image output by a designated camera cluster 100. The first power supply command is a command to control the power supply device 200 to supply power to the designated camera cluster 100, and the simulated image is an image to be displayed to the user.

[0051] In other words, server 300 can respond to the user's image acquisition command by outputting a first power supply command to power supply device 200, so that power supply device 200 supplies power to designated camera cluster 100, enabling designated camera cluster 100 to output sampled images, generate simulated images based on point cloud model and sampled images, and feed the simulated images back to user terminal 400, so that the user can accurately determine the furnace conditions based on the simulated images, thereby improving the user's work efficiency.

[0052] In some embodiments, such as Figure 2As shown, the camera cluster 100 includes at least two cameras, a cooling fan 20 installed inside each camera, and a first control circuit. The cooling fan 20 dissipates heat from the inside of the camera to cool it down. The first control circuit is electrically connected to both the camera and the cooling fan 20, and is also connected to a power supply 200. The power supply 200 can simultaneously power both the camera and the cooling fan 20 to reduce the risk of camera overheating and damage while monitoring. Furthermore, the at least two cameras are a first camera 11 and a second camera 12. The first camera 11 is installed on the inner wall of the first furnace tube, and the second camera 12 is installed on the inner wall of the second furnace tube; the first and second furnace tubes are interconnected. In other words, since the blast furnace has multiple channels—multiple feed channels, waste channels, and discharge channels—each channel is composed of multiple furnace tubes; that is, each channel can be composed of a first furnace tube and a second furnace tube. The first furnace tube and the second furnace tube can be collinear, perpendicular, or at a certain angle along their length. A first camera 11 can be installed on the first furnace tube, and a second camera 12 can be installed on the second furnace tube, so that images reflecting the situation inside the channel can be captured by the first camera 11 and the second camera 12.

[0053] In some embodiments, the power supply device 200 includes a second control chip 21 and a conversion circuit. The second control chip 21 is communicatively connected to the server 300 and the first control circuit, respectively. The first end of the conversion circuit is electrically connected to the second control chip 21. The connection point between the second end of the conversion circuit and the first control circuit is connected to the camera. The connection point between the third end of the conversion circuit and the first control circuit is connected to the cooling fan 20.

[0054] In other words, since the power supply voltage required by the cooling fan 20 is different from that required by the camera, a conversion circuit can be used to output different power supply voltages to power both the cooling fan 20 and the camera.

[0055] In some embodiments, the conversion circuit includes a primary-side conversion circuit, a transformer, a first secondary-side conversion circuit, and a second secondary-side conversion circuit. The first control circuit includes a first switch, a second switch, and a first control chip 13. Specifically, the first terminal of the primary-side conversion circuit is connected to a power supply, the second terminal of the primary-side conversion circuit is connected to the primary winding of the transformer, the first secondary winding of the transformer is connected to the first secondary-side conversion circuit, and the second secondary winding of the transformer is connected to the second secondary-side conversion circuit. The second terminal of the first switch is connected to the first control chip 13, the first terminal of the first switch is connected to the first secondary-side conversion circuit, and the third terminal of the first switch is connected to a camera. The second terminal of the second switch is connected to the first control chip 13, the first terminal of the first switch is connected to the second secondary-side conversion circuit, and the third terminal of the second switch is connected to a cooling fan 20.

[0056] by Figure 2 For example, the primary-side switching circuit includes switching transistors Q1-Q4, capacitor C1, and inductor L1. The connection point between the source of switching transistor Q1 and the drain of switching transistor Q2 is connected to one end of inductor L1. The other end of inductor L1 is connected to one end of the primary winding of transformer T1. The other end of the primary winding of transformer T1 is connected to one end of capacitor C1. The connection point between the source of switching transistor Q3 and the drain of switching transistor Q4 is connected to the other end of capacitor C1. The connection point between switching transistors Q1 and Q3 is connected to the positive terminal of the power supply Vcc. The connection point between switching transistors Q2 and Q4 is connected to the negative terminal of the power supply Vcc. The first secondary-side switching circuit includes switching transistors Q5-Q7, capacitor C2, and inductor L2. The connection point between the source of switching transistor Q5 and the drain of switching transistor Q6 is connected to one end of inductor L2. The other end of inductor L2 is connected to one end of the first secondary winding of transformer T1. The other end of the first secondary winding of transformer T1 is connected to one end of capacitor C2. The connection point between the source of switching transistor Q7 and the drain of switching transistor Q8 is connected to the other end of capacitor C2. The connection point between switching transistors Q5 and Q7 is connected to the first terminal (i.e., the source) of the first switch Q100. The connection point between switching transistors Q6 and Q8 is connected to the system ground terminal. The second secondary-side switching circuit includes switching transistors Q9-Q12, capacitor C3, and inductor L3. The connection point between the source of switching transistor Q9 and the drain of switching transistor Q10 is connected to one end of inductor L3. The other end of inductor L3 is connected to one end of the second secondary winding of transformer T1. The other end of the second secondary winding of transformer T1 is connected to one end of capacitor C3. The connection point between the source of switching transistor Q11 and the drain of switching transistor Q12 is connected to the other end of capacitor C3. The connection point between switching transistors Q9 and Q1 is connected to the first end (i.e., the source) of the second switch Q200. The connection point between switching transistors Q10 and Q12 is connected to the system ground terminal. The gates of switching transistors Q1-Q12 are electrically connected to the second control chip 21, enabling the second control chip 21 to control the switching transistors Q1-Q4 to conduct alternately, the switching transistors Q5-Q8 to conduct alternately, and the switching transistors Q9-Q12 to conduct alternately. This converts the DC power output from the power supply Vcc into AC power output to the transformer T1. The first secondary-side conversion circuit can convert the AC power output from the transformer T1 into 5V DC power output to the first switch Q100, and the second secondary-side conversion circuit can convert the AC power output from the transformer T1 into 10V DC power output to the second switch Q200.

[0057] In this configuration, server 300 outputs a first power supply command to power supply device 200. Second control chip 21, in response to the first power supply command, outputs a first conduction signal to first control chip 13 of designated camera cluster 100, and outputs a second conduction signal to the gates of switching transistors Q1-Q12, causing switching transistors Q1-Q4, Q5-Q8, and Q9-Q12 to conduct alternately. First control chip 13, in response to the first conduction signal, outputs a high-level signal to first switch Q100, causing first switch Q100 to conduct, allowing power supply Vcc to power first camera 11 and second camera 12. First control chip 1313 has a built-in timing function, which can be preset to output a high-level signal to second switch Q200 after a first duration of outputting a high-level signal to first switch Q11, causing second switch Q200 to conduct, allowing power supply Vcc to also power cooling fan 2020.

[0058] In the embodiments of this disclosure, the memory of server 300 is used to store a computer program that controls the processor of server 300 to operate in order to implement the image processing method according to any embodiment. Those skilled in the art can design computer programs based on the solutions of the embodiments of this disclosure. How the computer program controls the processor to operate is well known in the art and will not be described in detail here.

[0059] <Method Implementation>

[0060] Figure 3 This is a flowchart illustrating an image processing method according to one embodiment. The implementing entity is, for example, a... Figure 1 Server 300.

[0061] like Figure 3 As shown, the image processing method of this embodiment may include the following steps S310 to S330:

[0062] In step S310, in response to the user's image acquisition command, a first power supply command is output to the power supply device.

[0063] In this embodiment, the user can output an image acquisition command through an application set on the user terminal. In response to the image acquisition command output by the user, the server can output a first power supply command to the power supply device to supply power to the specified camera cluster.

[0064] In some embodiments, step S310 specifically includes the following: in response to a user-output image acquisition command, determining the working state of the blast furnace; based on the working state, determining one of the camera clusters in at least one set of camera clusters as the designated camera cluster; wherein different working states correspond to different camera clusters; and generating and outputting a first power supply command to the power supply device based on the designated camera cluster.

[0065] The blast furnace's operating status can be divided into feeding status, processing status, first discharge status, and second discharge status. The first discharge status corresponds to the opening of the channel for conveying gaseous waste, and the second discharge status corresponds to the opening of the channel for outputting material. The server has pre-set mapping relationships; for example, the channel for conveying gaseous waste corresponds to camera cluster A, and the channel for outputting material corresponds to camera cluster B. The server can respond to user-inputted image acquisition commands and determine the blast furnace's operating status based on the specific operations being performed on the blast furnace's operating platform. For example, an operator can click the button on the operating platform corresponding to outputting waste, thus confirming that the specific operation is outputting waste.

[0066] In this embodiment, the server can generate and output a first power supply command to the power supply device. The first power supply command carries the identifier of the specified camera cluster. The second control chip can control the power supply device to perform voltage conversion. Furthermore, the second control chip feeds back the identifier of the specified camera cluster to the first control chip, so that the first control chip can control the power supply device to supply power to the first camera, the second camera, and the cooling fan of the specified camera cluster.

[0067] Step S320: Upon receiving the sampled image output by the designated camera cluster, generate a simulated image based on the preset point cloud model and the sampled image.

[0068] The first control chip of each camera in the camera cluster has the functions of data processing and data storage. It can preprocess the sampled images, such as removing blurry images, so that the sampled images output by the camera cluster to the server can be retrieved and used by users.

[0069] In some embodiments, step S320 specifically includes the following: according to the pre-stored locations of each camera in the specified camera cluster 100, the sampled images corresponding to each camera location are fused into a preset point cloud model to generate a simulated image.

[0070] Users can pre-build a point cloud model of the blast furnace. Based on the existing camera-point cloud transformation matrix, the coordinates of the sampled images corresponding to each camera position can be transformed into the point cloud model, thus constructing a new point cloud model, i.e., a simulated image.

[0071] Step S330: Send a simulated image to the user.

[0072] In some embodiments, after step S320, the method further includes: determining a first damage feature in the simulated image based on a preset damage feature model; and determining a damage type and a repair suggestion corresponding to the damage type based on the first damage feature. Accordingly, step S330 specifically includes: sending the simulated image, the damage type, and the repair suggestion to the user.

[0073] The damage types can include refractory material detachment, tuyere damage, etc., without limitation. Each damage type corresponds to different damage characteristics; for example, tuyere damage can manifest as the formation of a narrow, elongated air duct inside the pipe. The server pre-constructs corresponding damage characteristic models for each damage type, enabling it to identify a specific damage characteristic in the simulated image, i.e., the first damage characteristic. The server can also pre-store repair suggestions for different damage types; for example, tuyere damage might require operator patching, facilitating faster blast furnace repairs.

[0078] Image sending module 430 is used to send the simulated image to the user.

[0079] Optionally, the instruction output module 410 is further configured to, in response to the image acquisition instruction output by the user, determine the working state of the blast furnace; and, based on the working state, determine one of the camera clusters in at least one group of camera clusters as the designated camera cluster; wherein different working states correspond to different camera clusters; and, based on the designated camera cluster, generate and output a first power supply instruction to the power supply device.

[0080] Optionally, the image generation module 420 is further configured to fuse the sampled images corresponding to each of the specified camera positions into a preset point cloud model based on the pre-stored camera positions of the specified camera cluster, thereby generating a simulated image.
