Description

Technical Field

[0001] This invention relates to the field of feeding technology, and in particular to an automatic feeding control method and system, electronic equipment, and storage medium. Background Technology

[0002] Iron is an important metal. It is extracted from iron ore or recycled metal scrap, and is obtained by smelting the raw materials. Workers manually feed the raw materials into a smelting furnace, where the iron is reduced from oxides and melted into a liquid state, flowing out from the bottom of the furnace. Traditionally, the feeding method in smelting is manual. Workers typically rely on experience to judge the smelting progress and add materials accordingly. However, this can lead to misjudgments and delayed feeding, causing the molten iron to burn dry and posing a risk of production accidents. Furthermore, overfeeding can result in insufficient melting, leading to poor smelting quality. In addition, manual feeding is inefficient. Summary of the Invention

[0021] The first feeding speed is reduced based on the second speed change to obtain the second feeding speed.

[0024] In some embodiments, the step of performing data calculation processing on the infrared data to obtain the material height inside the furnace includes:

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0047] It should be noted that although a logical order is shown in the flowcharts in the description of this invention, in some cases, the steps shown or described may be performed in a different order than that shown in the flowcharts. In the description of this invention, "several" means one or more, and "more" means two or more. The terms "first" and "second" are used only to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0048] This invention provides an automatic feeding control method, an automatic feeding control system, an electronic device, and a computer-readable storage medium. By utilizing the automatic feeding control system, firstly, infrared thermal radiation images and data collected by an infrared temperature and distance measuring device, and multiple furnace pressure data collected by a furnace pressure sensor are acquired. Then, image analysis processing is performed on the infrared thermal radiation images to obtain furnace temperature distribution information. Next, data calculation processing is performed on the infrared data to obtain the material height inside the furnace. Then, data processing is performed on the multiple furnace pressure data to obtain furnace pressure distribution information and average furnace pressure. Next, if it is determined that the material height inside the furnace is less than a height safety threshold and the average furnace pressure is less than a pressure safety threshold, the furnace melting situation is determined based on the furnace temperature distribution information and furnace pressure distribution information. Then, based on the furnace melting situation, the current first feeding speed is adjusted to a second feeding speed. Finally, the feeding mechanism is controlled to operate at the second feeding speed to automatically feed materials, achieving automated feeding with adjustable feeding speed. Therefore, according to the embodiments of the present invention, the feeding speed can be adjusted according to the smelting conditions in the furnace, realizing automated feeding and improving smelting safety, smelting quality and smelting efficiency.

[0049] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0050] like Figure 1 As shown, Figure 1 This is a schematic diagram of a system framework for executing an automatic feeding control method according to an embodiment of the present invention. Figure 1In the example, the system framework includes an automatic feeding control system 110, an infrared temperature and distance measuring device 120, a furnace pressure sensor 130, and a feeding mechanism 140, wherein the automatic feeding control system 110 is communicatively connected to the infrared temperature and distance measuring device 120, the furnace pressure sensor 130, and the feeding mechanism 140, respectively.

[0051] The infrared temperature and distance measuring device 120 is used to scan the smelting furnace, collect infrared thermal radiation images and data, and send them to the automatic feeding control system 110 for processing. It should be noted that one or more infrared temperature and distance measuring devices 120 can be used. At least one infrared temperature and distance measuring device 120 should be positioned directly above the feeding port of the smelting furnace to obtain infrared data that can be used to calculate the material height inside the furnace. Alternatively, multiple infrared temperature and distance measuring devices 120 can be used to collect infrared thermal radiation images from different angles, which is beneficial for subsequent infrared radiation image analysis and processing to obtain more accurate furnace temperature distribution information. Therefore, this application does not impose a specific limitation on the number of infrared temperature and distance measuring devices 120 used.

[0052] The furnace pressure sensor 130 is used to collect furnace pressure data from multiple smelting furnaces and send the data to the furnace. It is understood that smelting furnaces are generally tubular, and the furnace pressure sensor 130 can collect multiple furnace pressure data points at various locations along the furnace body. Specifically, multiple pressure sampling points can be set at preset intervals along the furnace body in the vertical and circumferential directions to acquire multiple furnace pressure data points. Then, data processing is performed on the multiple furnace pressure data to obtain the furnace pressure distribution information, and the average furnace pressure is calculated by averaging the multiple furnace pressure data points.

[0053] The feeding mechanism 140 is used to automatically feed materials into the smelting furnace at a certain feeding speed under the control of the automatic feeding control system 110. It can be understood that the feeding mechanism can be a material conveyor belt or a movable robotic arm with material grippers.

[0054] The automatic feeding control system 110 is used to obtain the infrared thermal radiation image and infrared data collected by the infrared temperature measuring and ranging device 120, and the furnace pressure data collected by the furnace pressure sensor. It then performs image analysis processing on the infrared thermal radiation image to obtain the furnace temperature distribution information, performs data calculation processing on the infrared data to obtain the material height inside the furnace, and performs data processing on the multiple furnace pressure data to obtain the furnace pressure distribution information and the average furnace pressure. Subsequently, if it is determined that the material height inside the furnace is less than the height safety threshold and the average furnace pressure is less than the pressure safety threshold, it determines the furnace melting situation based on the furnace temperature distribution information and the furnace pressure distribution information. Based on the furnace melting situation, it adjusts the current first feeding speed to a second feeding speed. It controls the feeding mechanism to operate at the second feeding speed, automatically feeding materials, thus realizing automated feeding with adjustable feeding speed, improving melting safety, melting quality, and melting efficiency.

[0055] It will be understood by those skilled in the art that Figure 1 The system architecture shown does not constitute a limitation on the embodiments of the present invention and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0056] Based on the above system structure, various embodiments of the automatic feeding control method of the present invention are proposed below.

[0057] Firstly, referring to Figure 2 , Figure 2 This is a flowchart illustrating an automatic feeding control method according to an embodiment of the present invention. This automatic feeding control method can be applied to automatic feeding control systems, for example... Figure 1 The automatic feeding control system 110 is shown in the system framework. The automatic feeding control method may include, but is not limited to, steps S110 to S170.

[0058] Step S110: Acquire infrared thermal radiation images and infrared data collected by the infrared temperature and distance measuring device, and multiple furnace pressure data collected by the furnace pressure sensor.

[0059] In this step, infrared thermal radiation images, infrared data, and multiple furnace pressure data are acquired, providing a reliable data processing foundation for subsequent analysis of the smelting situation inside the furnace, which is conducive to achieving more reliable automated feeding.

[0060] It is understood that multiple pressure sampling points can be set at preset intervals along the vertical and circumferential directions of the furnace body to obtain multiple furnace pressure data; multiple pressure sampling points can also be set randomly on the furnace body; or the pressure inside the furnace can be detected by a high-temperature and high-pressure resistant furnace pressure sensor with a probe head; this application does not impose specific restrictions on the method of obtaining multiple furnace pressure data.

[0061] Step S120: Perform image analysis and processing on the infrared thermal radiation image to obtain the temperature distribution information inside the furnace.

[0062] In this step, image analysis and processing of infrared thermal radiation images are performed to obtain furnace temperature distribution information. Based on reliable image data, image processing is performed to obtain furnace temperature distribution information, providing reliable information for analyzing the furnace melting situation.

[0063] Specifically, the infrared temperature measurement and ranging device acquires the infrared thermal radiation image of the furnace tube through an optical imaging system suitable for colorimetric thermometry, based on the infrared radiation characteristics of the furnace tube. This image is then sent to the automatic feeding control system for image analysis and processing. Specifically, the automatic feeding control system uses digital image processing, pattern recognition, and computer vision measurement technologies to analyze and process the infrared radiation image, and utilizes colorimetric thermometry to obtain the real-time temperature distribution on the furnace tube surface, i.e., the temperature distribution information inside the furnace.

[0064] Step S130: Perform data calculation and processing on the infrared data to obtain the material height inside the furnace.

[0065] In this step, the height of the material inside the furnace is calculated by processing the infrared data. If the material height is too high, continuing to feed material may cause molten metal to splash, damaging surrounding equipment and posing a safety hazard. Therefore, the calculated material height reflects the smelting situation inside the furnace to some extent and can be used as one of the criteria to determine whether to continue feeding material into the furnace, providing reliable reference information for automated feeding.

[0066] Step S140: Process multiple furnace pressure data to obtain furnace pressure distribution information and average furnace pressure.

[0067] In this step, data processing is performed on multiple furnace pressure data points to obtain furnace pressure distribution information, and the average furnace pressure is calculated by averaging the multiple furnace pressure data points. The furnace pressure distribution information and the average furnace pressure can reflect the smelting conditions within the smelting furnace to a certain extent, providing reliable reference information for automated feeding.

[0068] Step S150: If it is determined that the material height in the furnace is less than the height safety threshold and the average pressure in the furnace is less than the pressure safety threshold, the melting situation in the furnace is determined based on the furnace temperature distribution information and furnace pressure distribution information.

[0069] In this step, before determining the melting conditions inside the furnace based on the furnace temperature and pressure distribution information, it is also necessary to determine whether the material height inside the furnace is less than the height safety threshold and whether the average furnace pressure is less than the pressure safety threshold. Only when it is determined that the material height inside the furnace is less than the height safety threshold and the average furnace pressure is less than the pressure safety threshold, thus ensuring the melting furnace is in a safe operating state, can the melting conditions inside the furnace be further determined, ensuring the structural safety of the melting furnace and the safety of the melting process.

[0070] It is understandable that smelting furnaces have certain design requirements from the outset. The pressure value can be calculated based on the structural strength required when designing the furnace wall and frame; this pressure value is the pressure safety threshold. The height safety threshold can be set based on the actual height of the smelting furnace. Therefore, this invention does not impose specific restrictions on the values ​​of the pressure safety threshold and the height safety threshold.

[0071] In some embodiments, if it is determined that the material height in the furnace is greater than or equal to the height safety threshold, or the average pressure in the furnace is greater than or equal to the pressure safety threshold, the second feeding speed is adjusted to zero and the feeding of materials is stopped.

[0072] It is understandable that uneven heating may occur during the melting process, leading to splashing of high-temperature liquid. If the material height inside the furnace is too high, the high-temperature liquid can easily splash out of the furnace. Continuing to add material when the material height is already too high can also cause splashing, damaging surrounding equipment and endangering personal safety. Furthermore, if the furnace operates under high pressure for an extended period, the pressure can deform the furnace lid, damaging the furnace structure and affecting melting quality and efficiency. Therefore, when the material height inside the furnace is greater than or equal to the height safety threshold, or the average furnace pressure is greater than or equal to the pressure safety threshold, the second feeding speed is adjusted to 0, effectively stopping the feeding mechanism. This ensures the structural safety of the furnace and the safety of the melting process, while also improving the efficiency of automatic control.

[0073] The following is a further explanation of "determining the smelting conditions in the furnace based on the furnace temperature distribution information and furnace pressure distribution information":

[0074] In some embodiments, when the furnace pressure distribution information is uniform and the furnace temperature distribution information is uniform, the furnace melting condition is determined to be that the material is completely melted.

[0075] In some embodiments, if the furnace pressure distribution information indicates uneven furnace pressure distribution, or the furnace temperature distribution information indicates uneven furnace temperature distribution, the furnace melting condition is determined to be that the material is not completely melted.

[0076] Understandably, when iron is smelted in a furnace, the material exists in different physical states under different smelting conditions. Specifically, when the material is fully smelted, it is in a liquid state, with uniform pressure and heating distribution within the furnace, i.e., uniform temperature distribution. However, when the material is not fully smelted, it is in a solid-liquid mixture or a pure solid state, resulting in uneven pressure and temperature distribution within the furnace. Therefore, analyzing both the furnace temperature and pressure distribution information to determine the smelting conditions can improve the accuracy and reliability of this assessment.

[0077] Step S160: Adjust the current first feeding speed to the second feeding speed according to the melting situation in the furnace.

[0078] In this step, the current first feeding speed is adjusted to the second feeding speed according to the smelting situation in the furnace. The second feeding speed is used to adjust the feeding speed in real time according to the smelting situation in the furnace, so as to balance smelting safety and smelting efficiency.

[0079] It is understandable that the melting process in the furnace includes two scenarios: one where the material is completely melted, and the other where the material is not completely melted. Different speed adjustment methods are used depending on the different melting scenarios. Specific details are as follows.

[0080] In some embodiments, when the material is completely melted in the furnace, the first velocity change is determined according to a preset first velocity change characteristic curve, wherein the first velocity change characteristic curve is a velocity change-furnace average pressure curve, and the velocity change and the furnace average pressure are negatively correlated; the first feeding speed is increased according to the first velocity change to obtain the second feeding speed.

[0081] Understandably, when materials are fully melted, the pressure distribution inside the furnace is uniform. However, the average pressure inside the furnace is uncertain at this point. If the average furnace pressure is already very close to the pressure safety threshold, the feeding rate should not be increased too quickly. Instead, the feeding rate should be increased by a smaller rate change, while ensuring the structural safety of the furnace. If the average furnace pressure is far below the pressure safety threshold, it indicates that the furnace is operating safely, and a larger rate change can be used to increase the current feeding rate. Based on this, a rate change-average furnace pressure curve can be pre-set, with the average furnace pressure on the horizontal axis and the rate change on the vertical axis. The rate change and the average furnace pressure are negatively correlated. That is, based on the first rate change characteristic curve, the first rate change can be determined according to the real-time average furnace pressure, controlling the magnitude of the feeding rate adjustment to achieve more accurate control, balancing melting safety and melting efficiency.

[0082] In some embodiments, when the material is not completely melted in the furnace, the second speed change is determined according to a preset second speed change characteristic curve, wherein the second speed change characteristic curve is a speed change-material height curve, and the speed change is positively correlated with the material height in the furnace; the first feeding speed is reduced according to the second speed change to obtain the second feeding speed.

[0083] Understandably, when materials are not fully melted, the pressure distribution inside the furnace is uneven, making it unsuitable to continue using the first velocity change characteristic curve to determine the second velocity change. When materials are not fully melted, their physical state changes during the melting process, causing variations in the material height inside the furnace. For example, when transitioning from a completely solid state to a solid-liquid coexistence state, the material height decreases, allowing for a smaller velocity change to adjust the current feeding rate. Conversely, as more material is fed, the material height rises, and when it approaches the safety threshold, a larger velocity change should be used to reduce the feeding rate. Therefore, a velocity change-furnace material height curve can be pre-set, with the horizontal axis representing the material height and the vertical axis representing the velocity change, showing a positive correlation between the two. This allows for the determination of the second velocity change based on the second velocity change characteristic curve and the material height, controlling the magnitude of the feeding rate adjustment for more accurate control, balancing melting safety and efficiency.

[0084] Step S170: Control the feeding mechanism to run at the second feeding speed to automatically feed materials.

[0085] In this step, the feeding mechanism operates at the updated second feeding speed under the control of the automatic feeding control system, automatically feeding materials into the smelting furnace. The feeding speed can be adjusted in real time according to the smelting situation in the furnace, realizing automated feeding and improving smelting safety, smelting quality and smelting efficiency.

[0086] Understandably, when the smelting conditions inside the furnace are stable and the feeding speed remains unchanged, the feeding mechanism operates at a constant speed at the second feeding speed, and the amount of material fed per unit time is constant.

[0087] Through steps S110 to S170, this embodiment of the invention can adjust the feeding speed according to the smelting situation in the furnace, realize automated feeding, and improve smelting safety, smelting quality and smelting efficiency.

[0088] Reference Figure 3 , Figure 3 yes Figure 2 A flowchart illustrating the specific method of step S130. Step S130 includes, but is not limited to, steps S210 to S230.

[0089] Step S210: Process the infrared data to obtain the first vertical distance between the infrared temperature measuring and ranging device set directly above the feeding port and the material in the smelting furnace.

[0090] Step S220: Obtain the preset second distance, which is the vertical distance between the infrared temperature measuring and ranging device set directly above the feeding port and the bottom surface of the melting furnace.

[0091] Step S230: Subtract the first distance from the second distance to obtain the material height inside the furnace.

[0092] In this embodiment of the invention, steps S210 to S230 are performed to process infrared data to obtain a first distance and a second distance, and the difference between the first distance and the second distance is calculated to obtain the material height inside the furnace. The calculation is simple and easy to implement.

[0093] Secondly, based on the various embodiments of the above-described automatic feeding control method, an automatic feeding control system capable of implementing the above embodiments is proposed. (Refer to...) Figure 4 , Figure 4 This is a schematic diagram of the structure of an automatic feeding control system provided in an embodiment of the present invention. The automatic feeding control system 110 includes: a data acquisition module 410, an image processing module 420, a first data processing module 430, a second data processing module 440, a judgment processing module 450, a speed adjustment module 460, and a feeding control module 470.

[0094] The data acquisition module 410 is used to acquire infrared thermal radiation images and infrared data collected by the infrared temperature and distance measuring device, and multiple furnace pressure data collected by the furnace pressure sensor.

[0095] The image processing module 420 is used to perform image analysis and processing on infrared thermal radiation images to obtain furnace temperature distribution information.

[0096] The first data processing module 430 is used to perform data calculation and processing on infrared data to obtain the height of the material inside the furnace.

[0097] The second data processing module 440 is used to process multiple furnace pressure data to obtain furnace pressure distribution information and average furnace pressure.

[0098] The judgment and processing module 450 is used to determine the melting situation in the furnace based on the furnace temperature distribution information and furnace pressure distribution information when the material height in the furnace is less than the height safety threshold and the average pressure in the furnace is less than the pressure safety threshold.

[0099] The speed adjustment module 460 is used to adjust the current first feeding speed to the second feeding speed according to the melting situation in the furnace.

[0100] The feeding control module 470 is used to control the feeding mechanism to automatically feed materials at the second feeding speed.

[0101] The automatic feeding control system 110 provided in this embodiment of the invention first acquires infrared thermal radiation images and infrared data collected by an infrared temperature measuring and ranging device, and multiple furnace pressure data collected by a furnace pressure sensor using a data acquisition module 410. Then, an image processing module 420 performs image analysis processing on the infrared thermal radiation images to obtain furnace temperature distribution information. Next, a first data processing module 430 performs data calculation processing on the infrared data to obtain the material height inside the furnace. Finally, a second data processing module 440 processes the multiple furnace pressure data. The system obtains information on the pressure distribution inside the furnace and the average pressure in the furnace. Then, the judgment and processing module 450 determines the smelting situation inside the furnace based on the temperature distribution and pressure distribution information when the material height inside the furnace is less than the height safety threshold and the average pressure in the furnace is less than the pressure safety threshold. Next, the speed adjustment module 460 adjusts the current first feeding speed to a second feeding speed according to the smelting situation inside the furnace. Finally, the feeding control module 470 controls the feeding mechanism to operate at the second feeding speed to automatically feed materials, achieving automated feeding with adjustable feeding speed. Therefore, the automatic feeding control system of this embodiment can adjust the feeding speed according to the smelting situation inside the furnace, achieving automated feeding and improving smelting safety, smelting quality, and smelting efficiency.
