Description

Technical Field

[0001] The present invention belongs to the technical field of steam energy leakage detection, and in particular relates to a method and system for capturing heat source images for steam energy leakage. Background Art

[0002] Steam energy is widely used in the industrial field for power transmission, heating and various industrial processes. However, steam leakage often occurs due to aging equipment, pipe wear or poor sealing. Such leakage not only leads to energy waste, but also may pose a serious threat to equipment operation and personnel safety. Therefore, accurate and timely detection and location of steam leakage points are essential to maintain the safe and efficient operation of industrial equipment.

[0003] In steam leak detection, heat source image capture technology is one of the commonly used methods. Through thermal imaging equipment, inspectors can identify areas where the surface temperature of the equipment is abnormally high, thereby locating possible leaks. However, in actual operation, superimposed heat sources behind the steam equipment often cause significant interference to the detection results. For example, pipes behind the equipment, adjacent equipment, or background heat sources will produce additional hot spots in the thermal imaging image. The presence of these superimposed heat sources may mask or blur the real steam leak signal, resulting in reduced positioning accuracy and even misjudgment.

[0004] Existing technologies have obvious deficiencies in dealing with the impact of superimposed heat sources behind steam equipment. Since it is impossible to scientifically and objectively eliminate the impact of these rear interference sources, traditional methods have difficulty providing accurate detection results in complex industrial environments. In addition, existing detection technologies generally lack systematic solutions based on multiple experimental verifications and cannot flexibly deal with various interferences in different actual situations. This results in the inability of existing technologies to effectively eliminate interference when faced with complex scenarios with superimposed heat sources, limiting their reliability and accuracy in practical applications.

[0053] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0054] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script.

[0055] Figure 1 A flow chart of a method provided by an embodiment of the present invention is shown.

[0056] Specifically, a method for capturing a heat source image of a steam energy leak comprises the following steps:

[0057] Step S100, obtaining a first thermal imaging image of the interference source area pre-recorded by a first thermal imaging camera, and a second thermal imaging image of the target steam equipment area recorded in real time by the first thermal imaging camera, analyzing the first thermal imaging image and the second thermal imaging image, and determining the hot spot area and its temperature value therein.

[0058] Please refer to Figure 8 , the preset simulation environment includes a simulation chamber, in which a first simulation panel, a second simulation panel and a second thermal imaging camera are provided;

[0059] The first simulation panel and the second simulation panel are in a parallel position relationship, and the centers of the two are on the same straight line. The second simulation panel is located between the first simulation panel and the second thermal imaging camera. The straight-line distance between the first simulation panel and the second simulation panel is the same as the straight-line distance between the target steam equipment area and the interference source area in reality.

[0060] A plurality of mounting holes are provided on the surfaces of the first simulation panel and the second simulation panel, and a simulated heat source is installed in the central area of ​​the mounting holes, and the simulated heat source is an electric heating sheet or a PTC heating element.

[0061] An appropriate distance is reserved between the simulated heat source and the inner wall of the installation hole, so that the heat can be distributed more evenly through the hole. Through these carefully designed hole structures, the heat superposition of the target steam equipment area and the interference source area can be effectively simulated at the overlap of the holes of the first simulation panel and the second simulation panel.

[0062] This layout can not only reproduce the superposition effect of two heat sources, but also help analyze the mutual influence between different heat sources. For example, in actual applications, the heat energy of the target steam equipment may be affected by the surrounding interference sources, causing the shape and temperature distribution of the hot spot to change. Through this hole design, when acquiring the thermal imaging image of the second simulation panel, this complex thermal energy interaction can be simulated more accurately, so as to better understand and predict the actual operation status of the equipment in the experimental environment, and ensure the accuracy and reliability of the final test results.

[0063] In the embodiment of the present invention, in order to obtain the first thermal imaging image in advance, it is necessary to use a high-precision first thermal imaging camera to statically shoot the interference source area. The first thermal imaging camera should be fixed in a suitable position to ensure the stability of the shooting, and record the heat source distribution and temperature information of the interference source under the same environmental conditions. These images will serve as a benchmark for subsequent analysis to eliminate the impact of the interference source on the target steam equipment area.

[0064] After shooting the interference source area, the first thermal imaging camera should be moved to the target steam equipment area and filmed in real time to capture the heat source distribution of the equipment under normal working conditions. Through such sequential operations, it can effectively ensure that the heat source images of each area are obtained under relatively stable conditions, which is conducive to subsequent accurate analysis.

[0065] It should be noted that the interference source area targeted by the present invention usually has a low-frequency heat source change, such as slow fluctuations in ambient temperature or low-power heat sinks around the device, etc. This means that the hot spot area of ​​the interference source remains relatively constant in a short period of time, which helps to stably obtain the reference image.

[0066] In the target steam equipment area, the first thermal imaging camera is used for real-time monitoring to capture thermal imaging images of the target steam equipment in working state. These real-time images record the current hot spot distribution and temperature values ​​of the target steam equipment area, which is convenient for subsequent analysis and comparison.

[0067] In order to determine the hot spot area and its temperature value, advanced image processing software can be used to analyze the thermal imaging image. Specific applied techniques include threshold segmentation, which detects the hot spot area by setting a temperature threshold to identify the area with higher temperature in the thermal imaging image. Edge detection algorithms, such as Canny edge detection, can also be used to accurately locate the boundaries of hot spots by identifying the edges of temperature changes in the image.

[0068] Once the hot spot areas are identified, pixel value extraction techniques can be used to extract temperature data in these areas. Most modern thermal imaging cameras, such as FLIR cameras, have built-in temperature measurement capabilities that can generate heat maps containing temperature information for each pixel. Using these techniques, the software can generate detailed temperature distribution maps and analyze temperature differences in hot spot areas, thereby providing monitoring data for equipment status.

[0069] For example, in industrial applications, FLIR Tools software can be used to analyze thermal imaging images of equipment surfaces, automatically detect and mark hot spots with abnormal temperatures, and generate temperature reports. These data can help engineers promptly detect potential equipment failures, such as pipeline leaks or overheating of electrical equipment, and then take preventive maintenance measures.

[0070] Furthermore, the method for capturing heat source images of steam energy leakage also includes the following steps:

[0071] Step S200, calling a preset simulation environment so that the simulated heat source area distribution and temperature values ​​on the first simulation panel are consistent with the hot spot area distribution and temperature values ​​of the first thermal imaging image.

[0072] Specifically, Figure 2 A flow chart for corresponding the first simulation panel to the first thermal imaging image is shown.

[0073] The step of calling the preset simulation environment so that the simulated heat source area distribution and the temperature value thereof on the first simulation panel are consistent with the hot spot area distribution and the temperature value thereof in the first thermal imaging image specifically includes the following steps:

[0074] Step S201, obtaining each hot spot area and its corresponding temperature value in the first thermal imaging image;

[0075] Step S202, mapping the first thermal imaging image to the first simulation panel to determine the simulated heat source areas corresponding to the different hot spot areas on the first thermal imaging image on the first simulation panel;

[0076] Step S203, according to the temperature value of each hot spot area on the first thermal imaging image, adjust the simulated heat source power in the corresponding simulated heat source area on the first simulation panel so that the temperature of the simulated heat source matches the temperature of the hot spot area.

[0077] In the embodiment of the present invention, in order to map the first thermal imaging image onto the first simulation panel, the coordinate system needs to be converted first. By defining reference points (such as the center or corners) on the image and the panel, a linear transformation or an affine transformation algorithm can be used to accurately map the hot spot area position in the thermal imaging image onto the simulation panel. This process ensures that each hot spot area in the image can accurately correspond to a specific area on the simulation panel.

[0078] After the mapping is completed, the hot spot area in the thermal imaging image will be divided into multiple sub-areas, each of which corresponds to one or more simulated heat source areas on the simulation panel. In this way, it is ensured that each simulated heat source area can reflect the hot spot distribution in the original thermal imaging image. The boundaries of these areas are marked on the simulation panel to guide subsequent power adjustment and temperature matching operations.

[0079] According to the temperature values ​​of each hot spot area in the thermal imaging image, a temperature-power relationship model is first established, and the power value required to simulate the heat source at each temperature is determined through experiments or theoretical calculations. Then, an adjustable power supply or other precision control device is used to adjust the input power of the simulated heat source so that its temperature gradually approaches and eventually matches the temperature of the corresponding hot spot area in the thermal imaging image.

[0080] During the adjustment process, the temperature of each simulated heat source is monitored in real time and compared with the temperature value in the original thermal imaging image. If there is a deviation, the system will automatically adjust the power through a closed-loop control system for fine-tuning. This feedback mechanism ensures that the temperature of each simulated heat source area can accurately reproduce the temperature distribution in the thermal imaging image, and ultimately the temperature distribution on the first simulated panel is completely consistent with the thermal imaging image.

[0081] It can be understood that mapping the second thermal imaging image to the second simulation panel is also implemented using the above solution.

[0082] Furthermore, the method for capturing heat source images of steam energy leakage also includes the following steps:

[0083] Step S300, based on the hot spot area distribution and temperature value of the second thermal imaging image, continuously debug the second simulation panel in the preset simulation environment. After each debugging, obtain the thermal imaging image of the second simulation panel through the second thermal imaging camera in the preset simulation environment, and compare it with the second thermal imaging image until it is determined that the two are consistent.

[0084] Specifically, Figure 3 A flow chart is shown for making the first simulation panel correspond to the first thermal imaging image and continuously debugging the second simulation panel.

[0085] According to the hot spot area distribution and temperature value of the second thermal imaging image, the second simulation panel in the preset simulation environment is continuously debugged. After each debugging, the thermal imaging image of the second simulation panel is obtained by the second thermal imaging camera in the preset simulation environment, and the thermal imaging image is compared with the second thermal imaging image until it is determined that the two are consistent. Specifically, the following steps are included:

[0086] Step S301, obtaining each hot spot area and its corresponding temperature value in the second thermal imaging image;

[0087] Step S302, mapping the second thermal imaging image to the second simulation panel to determine the simulated heat source area corresponding to each hot spot area on the second simulation panel, and gradually adjusting the power of the corresponding simulated heat source area according to the temperature value of each hot spot area on the second thermal imaging image, so that its temperature is gradually lower than the temperature in the second thermal imaging image;

[0088] Step S303, after each adjustment, a thermal imaging image of the second simulation panel is obtained by a second thermal imaging camera in a preset simulation environment, and the thermal imaging image is compared with the second thermal imaging image until the two are determined to be consistent.

[0089] When comparing the thermal imaging image of the second simulation panel acquired by the second thermal imaging camera with the second thermal imaging image, the differences in the distribution shape, position and temperature values ​​of the hot spot areas of the two are analyzed point by point. According to the comparison results, the power of each simulated heat source on the second simulation panel is continued to be adjusted until the shape, position and temperature values ​​of the hot spot areas of the thermal imaging image of the second simulation panel are gradually consistent with the second thermal imaging image.

[0090] In an embodiment of the present invention, during the debugging process, first obtain the distribution position of each hot spot area in the second thermal imaging image and its corresponding temperature value. Map these hot spot areas to the second simulation panel, and determine the simulated heat source area corresponding to each hot spot area on the simulation panel. According to the temperature value in the second thermal imaging image, gradually adjust the power of these simulated heat source areas so that their temperature is gradually lower than the temperature in the second thermal imaging image. After each adjustment, obtain the thermal imaging image of the simulation panel in real time through the second thermal imaging camera, and compare it with the original second thermal imaging image point by point, focusing on analyzing the distribution shape, position and temperature value differences of the hot spot area. According to these comparison results, continue to adjust the power of the simulated heat source until the thermal imaging image on the simulation panel is completely consistent with the second thermal imaging image in shape, position and temperature value.

[0091] In order to reduce the workload of debugging, the method of regional debugging can be adopted. The entire simulation panel is divided into several areas, and adjustments are made one by one according to the location of the hot spots corresponding to each area. For example, if there are several obvious high-temperature areas in the second thermal imaging image, the simulated heat sources corresponding to these high-temperature areas can be adjusted first, so that the temperatures of these areas gradually approach but are slightly lower than the target temperature. Then other areas with lower temperatures can be processed. Through this partitioned debugging, the complexity and workload of adjusting all simulated heat sources at one time can be avoided.

[0092] Debugging by region can not only reduce the workload of debugging, but also improve the accuracy of debugging. For example, in a complex thermal imaging image, some hot spot areas may be affected by surrounding heat sources, resulting in large temperature changes. Through regional debugging, these complex areas can be solved first to ensure that the temperature of each area is accurately matched, and then the overall fine-tuning can be performed. Assuming that there is a hot spot with a high central temperature and multiple hot spots with lower peripheral temperatures in the thermal imaging image of a certain device, the technician can first adjust the heat source in the central area to ensure that its temperature is slightly lower than the temperature in the second thermal imaging image, and then adjust the heat source in the peripheral area. Finally, through gradual adjustment and comparison, the precise debugging of the entire panel is completed.

[0093] Furthermore, the method for capturing heat source images of steam energy leakage also includes the following steps:

[0094] Step S400, after determining that the thermal imaging image acquired from the second simulation panel is consistent with the second thermal imaging image, the first simulation panel is initialized, and the thermal imaging image of the second simulation panel is acquired again to obtain a corrected thermal imaging image.

[0095] Specifically, Figure 4 A flow chart for generating a corrected thermal imaging image is shown.

[0096] After determining that the thermal imaging image obtained from the second simulation panel is consistent with the second thermal imaging image, initializing the first simulation panel and obtaining the thermal imaging image of the second simulation panel again to obtain the corrected thermal imaging image specifically includes the following steps:

[0097] Step S401, after determining that the thermal imaging image acquired from the second simulation panel is consistent with the second thermal imaging image, the first simulation panel is initialized, that is, all simulated heat sources on the first simulation panel are turned off;

[0098] Step S402, obtaining a thermal imaging image of the second simulation panel after the first simulation panel is initialized;

[0099] Step S403, obtaining a corrected thermal imaging image and using it as a reference thermal imaging image for determining whether steam energy leakage occurs in the target steam equipment area.

[0100] In an embodiment of the present invention, when all simulated heat sources on the first simulated panel are turned off, in order to prevent the residual heat from continuing to affect the experimental results, the following measures can be taken: First, ensure that the first simulated panel cools down quickly after being turned off. A forced cooling method can be used, such as using a fan, a coolant circulation system or other fast heat dissipation equipment to accelerate the cooling process of the panel. Secondly, wait until the temperature of the first simulated panel is completely restored to the ambient temperature before continuing the experiment. This method can effectively eliminate the influence of the residual heat after the heat source is turned off on the thermal imaging image of the second simulated panel, ensuring that the corrected thermal imaging image obtained is accurate.

[0101] The corrected thermal image is used as a reference thermal image to determine whether steam energy leakage occurs in the target steam equipment area. The basis is that the image has been calibrated and adjusted many times, fully considering the influence of interference sources, and simulating the actual heat energy distribution of the equipment in a real environment. The corrected thermal image provides a strictly compared and adjusted benchmark for detecting whether subsequent temperature changes are abnormal. The specific benefit is that it can improve the accuracy of leak detection, reduce false alarms and missed alarms, and ensure the reliability and accuracy of the detection results.

[0102] Compared with the existing technology, the advantage of this solution is that it eliminates the influence of interference sources and obtains an accurate reference thermal imaging image through multiple calibrations and debugging in a simulated environment. In traditional leak detection technology, it is often impossible to completely eliminate interference factors in the environment, resulting in certain errors in the detection results. Through this solution, it is possible to more accurately determine whether steam energy leakage has occurred in the target steam equipment area, thereby significantly improving the reliability and accuracy of detection, especially in complex industrial environments, and more effectively identifying and handling potential equipment failures.

[0103] Furthermore, Figure 5 The application architecture diagram of the system provided by the embodiment of the present invention is shown.

[0104] Among them, in another preferred embodiment provided by the present invention, a heat source image capture system for steam energy leakage includes:

[0105] The image acquisition module 100 is used to acquire a first thermal imaging image of the interference source area pre-recorded by a first thermal imaging camera, and a second thermal imaging image of the target steam equipment area recorded in real time by the first thermal imaging camera, analyze the first thermal imaging image and the second thermal imaging image, and determine the hot spot area and its temperature value.

[0106] The preset simulation environment includes a simulation chamber, in which a first simulation panel, a second simulation panel and a second thermal imaging camera are arranged;

[0107] The first simulation panel and the second simulation panel are in a parallel position relationship, and the centers of the two are on the same straight line. The second simulation panel is located between the first simulation panel and the second thermal imaging camera. The straight-line distance between the first simulation panel and the second simulation panel is the same as the straight-line distance between the target steam equipment area and the interference source area in reality.

[0108] A plurality of mounting holes are provided on the surfaces of the first simulation panel and the second simulation panel, and a simulated heat source is installed in the central area of ​​the mounting holes, and the simulated heat source is an electric heating sheet or a PTC heating element.

[0109] An appropriate distance is reserved between the simulated heat source and the inner wall of the installation hole, so that the heat can be distributed more evenly through the hole. Through these carefully designed hole structures, the heat superposition of the target steam equipment area and the interference source area can be effectively simulated at the overlap of the holes of the first simulation panel and the second simulation panel.

[0110] This layout can not only reproduce the superposition effect of two heat sources, but also help analyze the mutual influence between different heat sources. For example, in actual applications, the heat energy of the target steam equipment may be affected by the surrounding interference sources, causing the shape and temperature distribution of the hot spot to change. Through this hole design, when acquiring the thermal imaging image of the second simulation panel, this complex thermal energy interaction can be simulated more accurately, so as to better understand and predict the actual operation status of the equipment in the experimental environment, and ensure the accuracy and reliability of the final test results.

[0111] In the embodiment of the present invention, in order to obtain the first thermal imaging image in advance, it is necessary to use a high-precision first thermal imaging camera to statically shoot the interference source area. The first thermal imaging camera should be fixed in a suitable position to ensure the stability of the shooting, and record the heat source distribution and temperature information of the interference source under the same environmental conditions. These images will serve as a benchmark for subsequent analysis to eliminate the impact of the interference source on the target steam equipment area.

[0112] After shooting the interference source area, the first thermal imaging camera should be moved to the target steam equipment area and filmed in real time to capture the heat source distribution of the equipment under normal working conditions. Through such sequential operations, it can effectively ensure that the heat source images of each area are obtained under relatively stable conditions, which is conducive to subsequent accurate analysis.

[0113] It should be noted that the interference source area targeted by the present invention usually has a low-frequency heat source change, such as slow fluctuations in ambient temperature or low-power heat sinks around the device, etc. This means that the hot spot area of ​​the interference source remains relatively constant in a short period of time, which helps to stably obtain the reference image.

[0114] In the target steam equipment area, the first thermal imaging camera is used for real-time monitoring to capture thermal imaging images of the target steam equipment in working state. These real-time images record the current hot spot distribution and temperature values ​​of the target steam equipment area, which is convenient for subsequent analysis and comparison.

[0115] In order to determine the hot spot area and its temperature value, advanced image processing software can be used to analyze the thermal imaging image. Specific applied techniques include threshold segmentation, which detects the hot spot area by setting a temperature threshold to identify the area with higher temperature in the thermal imaging image. Edge detection algorithms, such as Canny edge detection, can also be used to accurately locate the boundaries of hot spots by identifying the edges of temperature changes in the image.

[0116] Once the hot spot areas are identified, pixel value extraction techniques can be used to extract temperature data in these areas. Most modern thermal imaging cameras, such as FLIR cameras, have built-in temperature measurement capabilities that can generate heat maps containing temperature information for each pixel. Using these techniques, the software can generate detailed temperature distribution maps and analyze temperature differences in hot spot areas, thereby providing monitoring data for equipment status.

[0117] For example, in industrial applications, FLIR Tools software can be used to analyze thermal imaging images of equipment surfaces, automatically detect and mark hot spots with abnormal temperatures, and generate temperature reports. These data can help engineers promptly detect potential equipment failures, such as pipeline leaks or overheating of electrical equipment, and then take preventive maintenance measures.

[0118] Furthermore, the steam energy leakage heat source image capture system also includes:

[0119] The first simulation panel debugging module 200 is used to call a preset simulation environment so that the simulated heat source area distribution and temperature values ​​on the first simulation panel are consistent with the hot spot area distribution and temperature values ​​of the first thermal imaging image.

[0120] Specifically, Figure 6 It shows a structural block diagram of the first simulation panel debugging module 200 in the system provided by the embodiment of the present invention.

[0121] Among them, in the preferred embodiment provided by the present invention, the first simulation panel debugging module 200 specifically includes:

[0122] The first data acquisition unit 201 is used to acquire each hot spot area and its corresponding temperature value in the first thermal imaging image;

[0123] The area and value matching unit 202 is used to map the first thermal imaging image to the first simulation panel to determine the simulated heat source areas corresponding to the different hot spot areas on the first thermal imaging image on the first simulation panel;

[0124] The first simulation panel debugging unit 203 is used to adjust the simulated heat source power in the simulated heat source area on the corresponding first simulation panel according to the temperature value of each hot spot area on the first thermal imaging image, so that the temperature of the simulated heat source matches the temperature of the hot spot area.

[0125] In the embodiment of the present invention, in order to map the first thermal imaging image onto the first simulation panel, the coordinate system needs to be converted first. By defining reference points (such as the center or corners) on the image and the panel, a linear transformation or an affine transformation algorithm can be used to accurately map the hot spot area position in the thermal imaging image onto the simulation panel. This process ensures that each hot spot area in the image can accurately correspond to a specific area on the simulation panel.

[0126] After the mapping is completed, the hot spot area in the thermal imaging image will be divided into multiple sub-areas, each of which corresponds to one or more simulated heat source areas on the simulation panel. In this way, it is ensured that each simulated heat source area can reflect the hot spot distribution in the original thermal imaging image. The boundaries of these areas are marked on the simulation panel to guide subsequent power adjustment and temperature matching operations.

[0127] According to the temperature values ​​of each hot spot area in the thermal imaging image, a temperature-power relationship model is first established, and the power value required to simulate the heat source at each temperature is determined through experiments or theoretical calculations. Then, an adjustable power supply or other precision control device is used to adjust the input power of the simulated heat source so that its temperature gradually approaches and eventually matches the temperature of the corresponding hot spot area in the thermal imaging image.

[0128] During the adjustment process, the temperature of each simulated heat source is monitored in real time and compared with the temperature value in the original thermal imaging image. If there is a deviation, the system will automatically adjust the power through a closed-loop control system for fine-tuning. This feedback mechanism ensures that the temperature of each simulated heat source area can accurately reproduce the temperature distribution in the thermal imaging image, and ultimately the temperature distribution on the first simulated panel is completely consistent with the thermal imaging image.

[0129] It can be understood that mapping the second thermal imaging image to the second simulation panel is also implemented using the above solution.

[0130] Furthermore, the steam energy leakage heat source image capture system also includes:

[0131] The second simulation panel debugging module 300 is used to continuously debug the second simulation panel in the preset simulation environment according to the hot spot area distribution and temperature value of the second thermal imaging image. After each debugging, the thermal imaging image of the second simulation panel is obtained by the second thermal imaging camera in the preset simulation environment, and it is compared with the second thermal imaging image until it is determined that the two are consistent.

[0132] Specifically, Figure 7 It shows a structural block diagram of the second simulation panel debugging module 300 in the system provided by the embodiment of the present invention.

[0133] Among them, in the preferred embodiment provided by the present invention, the second simulation panel debugging module 300 specifically includes:

[0134] The second data acquisition unit 301 is used to acquire each hot spot area and its corresponding temperature value in the second thermal imaging image;

[0135] The second simulation panel debugging unit 302 is used to map the second thermal imaging image to the second simulation panel to determine the simulated heat source area corresponding to each hot spot area on the second simulation panel, and gradually adjust the power of the corresponding simulated heat source area according to the temperature value of each hot spot area on the second thermal imaging image, so that its temperature is gradually lower than the temperature in the second thermal imaging image;

[0136] The image comparison unit 303 is used to obtain a thermal imaging image of the second simulation panel through a second thermal imaging camera in a preset simulation environment after each adjustment, and compare the thermal imaging image with the second thermal imaging image until the two are determined to be consistent.

[0137] When comparing the thermal imaging image of the second simulation panel acquired by the second thermal imaging camera with the second thermal imaging image, the differences in the distribution shape, position and temperature values ​​of the hot spot areas of the two are analyzed point by point. According to the comparison results, the power of each simulated heat source on the second simulation panel is continued to be adjusted until the shape, position and temperature values ​​of the hot spot areas of the thermal imaging image of the second simulation panel are gradually consistent with the second thermal imaging image.

[0138] In an embodiment of the present invention, during the debugging process, first obtain the distribution position of each hot spot area in the second thermal imaging image and its corresponding temperature value. Map these hot spot areas to the second simulation panel, and determine the simulated heat source area corresponding to each hot spot area on the simulation panel. According to the temperature value in the second thermal imaging image, gradually adjust the power of these simulated heat source areas so that their temperature is gradually lower than the temperature in the second thermal imaging image. After each adjustment, obtain the thermal imaging image of the simulation panel in real time through the second thermal imaging camera, and compare it with the original second thermal imaging image point by point, focusing on analyzing the distribution shape, position and temperature value differences of the hot spot area. According to these comparison results, continue to adjust the power of the simulated heat source until the thermal imaging image on the simulation panel is completely consistent with the second thermal imaging image in shape, position and temperature value.

[0139] In order to reduce the workload of debugging, the method of regional debugging can be adopted. The entire simulation panel is divided into several areas, and adjustments are made one by one according to the location of the hot spots corresponding to each area. For example, if there are several obvious high-temperature areas in the second thermal imaging image, the simulated heat sources corresponding to these high-temperature areas can be adjusted first, so that the temperatures of these areas gradually approach but are slightly lower than the target temperature. Then other areas with lower temperatures can be processed. Through this partitioned debugging, the complexity and workload of adjusting all simulated heat sources at one time can be avoided.

[0140] Debugging by region can not only reduce the workload of debugging, but also improve the accuracy of debugging. For example, in a complex thermal imaging image, some hot spot areas may be affected by surrounding heat sources, resulting in large temperature changes. Through regional debugging, these complex areas can be solved first to ensure that the temperature of each area is accurately matched, and then the overall fine-tuning can be performed. Assuming that there is a hot spot with a high central temperature and multiple hot spots with lower peripheral temperatures in the thermal imaging image of a certain device, the technician can first adjust the heat source in the central area to ensure that its temperature is slightly lower than the temperature in the second thermal imaging image, and then adjust the heat source in the peripheral area. Finally, through gradual adjustment and comparison, the precise debugging of the entire panel is completed.

[0141] Furthermore, the steam energy leakage heat source image capture system also includes:

[0142] The corrected thermal imaging image generation module 400 is used to initialize the first simulation panel after determining that the thermal imaging image obtained from the second simulation panel is consistent with the second thermal imaging image, and obtain the thermal imaging image of the second simulation panel again to obtain a corrected thermal imaging image.

[0143] In an embodiment of the present invention, when all simulated heat sources on the first simulated panel are turned off, in order to prevent the residual heat from continuing to affect the experimental results, the following measures can be taken: First, ensure that the first simulated panel cools down quickly after being turned off. A forced cooling method can be used, such as using a fan, a coolant circulation system or other fast heat dissipation equipment to accelerate the cooling process of the panel. Secondly, wait until the temperature of the first simulated panel is completely restored to the ambient temperature before continuing the experiment. This method can effectively eliminate the influence of the residual heat after the heat source is turned off on the thermal imaging image of the second simulated panel, ensuring that the corrected thermal imaging image obtained is accurate.

[0144] The corrected thermal image is used as a reference thermal image to determine whether steam energy leakage occurs in the target steam equipment area. The basis is that the image has been calibrated and adjusted many times, fully considering the influence of interference sources, and simulating the actual heat energy distribution of the equipment in a real environment. The corrected thermal image provides a strictly compared and adjusted benchmark for detecting whether subsequent temperature changes are abnormal. The specific benefit is that it can improve the accuracy of leak detection, reduce false alarms and missed alarms, and ensure the reliability and accuracy of the detection results.

[0145] Compared with the existing technology, the advantage of this solution is that it eliminates the influence of interference sources and obtains an accurate reference thermal imaging image through multiple calibrations and debugging in a simulated environment. In traditional leak detection technology, it is often impossible to completely eliminate interference factors in the environment, resulting in certain errors in the detection results. Through this solution, it is possible to more accurately determine whether steam energy leakage has occurred in the target steam equipment area, thereby significantly improving the reliability and accuracy of detection, especially in complex industrial environments, and more effectively identifying and handling potential equipment failures.
