[0026] The sterilization control method of the water supply device provided by the embodiments of the present invention can be applied to a water supply device as Figure 1A shown.

[0027] Please refer to Figures 1B - 1D , the water supply device includes a body 101, and the body 101 is composed of a housing 203, a heat exchange mounting shell 202, a first side plate 201, a second side plate 204, a mounting bracket 301, a water circuit mounting seat 401, a heat preservation frame plate 302, and a tank 303.

[0028] Refer to Figure 1B and Figure 1C, the first side plate 201 is fixedly installed on one side of the housing 203 by screws, the second side plate 204 is fixedly installed on the side of the housing 203 away from the first side plate 201 by screws, the mounting bracket 301 is fixedly installed in the middle inside the housing 203, the waterway mounting base 401 is fixedly installed on the top of the mounting bracket 301, the heat exchange mounting shell 202 is fixedly assembled inside the housing 203, the tank body 303 is located inside the mounting bracket 301, and the tank body 303 is fixedly connected to the mounting bracket 301 by screws, and the heat preservation frame plate 302 is sleeved outside the tank body 303.

In this way, the overall assembly of this water supply device can be realized.

[0030] Refer to Figure 1D An internal electric heating coil 4033 is installed at the bottom of the waterway mounting base 401. The water liquid inside the tank body 303 can be heated by the provided internal electric heating coil 4033.

The cold water after heat exchange by the heat exchanger can be replenished into the tank body 303 as makeup water after heat exchange.

[0032] Based on Figures 1B - 1D The described water supply device can achieve the following functions:

[0033] Obtain a status detection signal, where the status detection signal is used to indicate the status detection of the tank body for storing the heat exchange medium in the water supply device;

[0034] Respond to the status detection signal and obtain the water level information set and water volume loss information in the tank body;

[0035] Determine the target status information of the tank body according to the water level information set and the water volume loss information.

[0036] In the embodiments of the present application, by obtaining a status detection signal and performing status detection on the tank for storing the heat exchange medium in the water supply device according to the status detection signal, it is convenient to accurately grasp the status information of the tank, ensure the stable operation of the water supply device, and then by responding to the status detection signal, collecting the water level information and water loss information in the tank, and determining the target status information of the tank according to the water level information set and the water loss information, which helps to achieve the purpose of comprehensively and accurately reflecting the true status of the water supply device.

[0037] Please refer to Figure 2 as shown in Figure 2 FIG. 1, which is a schematic flowchart of a method for determining the status of a water supply device provided by an embodiment of the present invention, including the following steps:

[0038] S1: Obtain a status detection signal, where the status detection signal is used to indicate performing status detection on the tank for storing the heat exchange medium in the water supply device.

[0039] Specifically, the status detection signal can be generated according to a preset time interval, which includes but is not limited to one day, one week, one month, and no specific limitation is made here. By regularly monitoring the tank status, it can be ensured that slow changes that may occur during the long-term use of the water supply device will not be missed; trigger conditions can also be preset. For example, when the heat exchange efficiency of the water supply device significantly decreases, the water temperature fluctuates beyond the normal range, the energy consumption abnormally increases, etc., it may indicate that the tank has an abnormal status and affects the normal heat exchange process. At this time, a status detection signal is generated to timely investigate the cause of the abnormality of the tank; the status detection signal can also be directly generated according to actual needs. For example, when some small faults that are suspected to be related to the tank but are not clear occur in the water supply device, the status detection signal can be manually sent by operating the relevant control interface or the button on the water supply device, and no specific limitation is made here.

[0040] It can be seen that by timely generating the status detection signal and detecting the tank in the subsequent process, it helps to always grasp the tank status and ensure that it is in the best working state.

[0041] S2: Respond to the status detection signal and obtain the water level information set and water loss information in the tank.

[0042] Among them, the water level information set in the tank can be obtained through sensors, etc. The water level information in the water level information set includes the water level information at multiple detection times. For example, the water level in the tank at each detection time is obtained by performing water level detection according to a preset detection period. And the water loss information is detected using the same detection period as the water level information detection to obtain the water loss information.

[0043] S3: Determine the target status information of the tank according to the water level information set and the water loss information.

[0044] Among them, a water level change curve can be constructed using the water level information set, and then a reference status information can be determined according to the water level change curve, and another reference status information can be determined using the water loss information. Finally, the target status information is determined based on the two reference status information. The target status information may include that there is no abnormal water level change in the tank and there is an abnormal water level change in the tank.

[0045] In this example, by obtaining the status detection signal and performing status detection on the tank for storing the heat exchange medium in the water supply device according to the status detection signal, it is convenient to accurately grasp the status information of the tank and ensure the stable operation of the water supply device. Then, by responding to the status detection signal, the water level information set and the water loss information in the tank, and determining the target status information of the tank according to the water level information set and the water loss information, it helps to achieve the purpose of comprehensively and accurately reflecting the true status of the water supply device.

[0046] In a possible implementation manner, a method for determining the target status information of the tank according to the water level information set and the water loss information includes:

[0047] A1. Construct a water level change curve according to the water level information set to obtain a target water level change curve;

[0048] A2. Determine the first reference status information according to the target water level change curve;

[0049] A3. Determine the second reference status information according to the water loss information;

[0050] A4. Determine the target status information according to the first reference status information and the second reference status information.

[0051] Among them, the numerical value of the water level information in the water level information set can be used as the ordinate, and the acquisition time of the water level information can be used as the abscissa, and set in the order of acquisition, and a discrete water level change curve can be obtained. The points in the discrete water level change curve are connected by a smooth curve to obtain the target water level change curve.

[0052] The inflection points of the target water level change curve can be extracted from the target water level change curve to obtain an inflection point set, and the first reference status information is determined according to the slope change information of the inflection points in the inflection point set. The first reference status information can be used to indicate whether there is an abnormality in the tank.

[0053] The water evaporation information of the tank body can be obtained, and then the second reference state information can be determined according to the water evaporation information and the water loss information. Since the water loss amount of the tank body is usually very close to the water evaporation amount in the normal state, if the deviation between the water loss amount and the water evaporation amount is large, it can indicate that the tank body is abnormal.

[0054] Finally, the target state information can be determined by combining the first reference state information and the second reference state information. Specifically, if both the first reference state information and the second reference state information indicate an abnormal state, the target state information is that the tank body is in an abnormal state; otherwise, it is determined that the tank body is in a normal state.

[0055] In a possible implementation, a method for determining the first reference state information according to the target water level change curve includes:

[0056] B1. Obtain the inflection points of the water level change curve to obtain a set of inflection points;

[0057] B2. Extract the slope change information at each inflection point in the set of inflection points to obtain a set of slope change information;

[0058] B3. Determine the first reference state information according to the set of slope change information.

[0059] Among them, an inflection point can be understood as a point where the slope changes. The slope of the curve on the left side of the inflection point may be different from the slope of the curve on the right side, so the change amount between the slope of the curve on the left side of the inflection point and the slope of the curve on the right side can be extracted and determined as the slope change information.

[0060] The greater the slope change, the greater the difference between the water level change rates before and after the inflection point. Since the water level gradually decreases over time, under normal circumstances, the water level drop due to evaporation will be a smooth process. However, it is also possible that due to an increase in the heating demand, the evaporation amount will increase, but it should also be within a proper range. Therefore, when the tank body is in a normal state, the slope change rate will be within a normal change range. If the slope change value indicated by the slope change information is outside this change range, it can be determined that the state indicated by the first reference state information is an abnormal state. If it is within this change range, the state indicated by the first reference state information is a normal state.

[0061] In a possible implementation, a method for determining the second reference state information according to the water loss information includes:

[0062] C1. Obtain the water evaporation information of the tank body;

[0063] C2. Calculate the first ratio between the water evaporation amount corresponding to the water evaporation information and the water loss amount corresponding to the water loss information;

[0064] C3. Determine the second reference state information according to the first ratio.

[0065] Specifically, the water evaporation information can be obtained by measuring from the steam discharge port of the tank. Under normal circumstances, since the water loss amount of the tank in the normal state is usually very close to the water evaporation amount, if the deviation between the water loss amount and the water evaporation amount is large, it can indicate that the tank is abnormal.

[0066] Among them, the water evaporation information can be obtained through sensors or other existing conventional technologies, which will not be elaborated here. Specifically, if the deviation value between the first ratio and 1 exceeds the preset deviation value threshold, the state indicated by the second reference state information is an abnormal state; otherwise, the state indicated by the second reference state information is a normal state.

[0067] In a possible implementation manner, warning processing can also be performed when the tank is in an abnormal state, as follows:

[0068] D1. Obtain the first image set of the tank;

[0069] D2. Determine the target three-dimensional image of the tank according to the first image set;

[0070] D3. Determine the abnormal information of the tank according to the target three-dimensional image;

[0071] D4. Determine the alarm information according to the abnormal information and the target state information;

[0072] D5. Send the alarm information to the server.

[0073] Specifically, the image information of the tank body can be obtained through an image acquisition device, which includes but is not limited to a high-definition camera, an infrared camera or an industrial camera, and no specific limitation is made here. Of course, the user can also take pictures by themselves and determine the taken pictures as the images in the first image set. Different shooting angles can show different characteristics of the tank body. The shooting angles of each camera can be planned to obtain representative and complementary images, that is, the image acquisition devices can be reasonably arranged according to the structure of the tank body and the areas to be monitored, and multiple cameras can be used to shoot simultaneously from different angles, including perspectives such as the front, side, top, bottom, etc., to ensure the acquisition of comprehensive image information of the tank body. For example, shooting from an oblique top can simultaneously see the top surface and part of the side surface of the tank body, which helps to observe the connection between the tank opening and the tank body and the overall shape of the side surface; shooting from the horizontal direction is more conducive to checking the flatness of the side surface of the tank body and whether there are bulges. Then, the comprehensive image information is integrated to obtain the first image set, which includes images from multiple different perspectives and under various conditions. During the image acquisition process, the clarity of each image is monitored in real time using an image clarity evaluation algorithm. If a blurred image is found, which may be caused by reasons such as inaccurate camera focusing, device shaking, or light change, an alarm will be issued in a timely manner and relevant parameters will be tried to be automatically adjusted, such as refocusing, stabilizing the device, or optimizing the light conditions, etc., to ensure that the acquired images all have sufficient clarity to meet the requirements of subsequent analysis. Among them, after the image acquisition, in order to ensure the accuracy of the data, the images can also be preprocessed, including denoising, sharpening, contrast adjustment, etc.

[0074] It can be seen that by obtaining the first image set, the tank body can be photographed and recorded from multiple angles and different orientations, realizing the visual presentation of all aspects such as the appearance and structure of the tank body, and providing an intuitive image basis for subsequent accurate analysis.

[0075] Among them, the specific steps of determining the target three-dimensional image of the tank body according to the first image set include:

[0076] Perform defect detection on the first images in the first image set to obtain a defect detection result set; extract abnormal defect detection results from the defect detection result set to obtain an abnormal defect inspection result set; extract the first images corresponding to the abnormal defect inspection result set to obtain a second image set; perform repair processing on the defect areas of each second image in the second image set to obtain a third image set; construct a three-dimensional image according to the third images in the third image set and the first images in the first image set to obtain the target three-dimensional image.

[0077] Specifically, the image noise of the first images in the first image set can be removed first by using image filtering techniques to enhance the clarity of the first images, facilitating subsequent accurate defect identification. For example, median filtering can be used to remove salt-and-pepper noise, and Gaussian filtering can be used to smooth the image while retaining edge details. Then, an edge detection algorithm is used to find the discontinuous parts of the object edges in the first images, determine whether there are possible defect edges, and then identify and analyze the detected edge regions to determine the specific shape and scope of the defects in the first images, thereby obtaining a defect detection result set. It should be noted that after obtaining the defect detection result set, not all detected defects represent actual abnormal conditions of the tank body. Some defects may be just minor interferences generated during the shooting process, such as small shadows occasionally appearing due to uneven lighting, and imaging of tiny dust on the lens, etc., which are defects within the normal acceptable range. Abnormal defects are related to the damage and poor condition of the tank body itself, such as obvious corrosion pits on the surface of the tank body, large-area scratches, suspected cracks, etc. Therefore, corresponding discrimination criteria can be preset, such as factors like the size threshold of the defects, shape characteristics, occurrence location and frequency, etc., to screen out the defect detection results reflecting the abnormality of the tank body from the entire set, obtaining an abnormal defect detection result set.

[0078] Next, the first images corresponding to the abnormal defect inspection result set are extracted from the defect detection result set to obtain a second image set, thereby improving the efficiency of the condition detection of the tank body and avoiding the repair and analysis of irrelevant images. Then, the defect regions of each second image in the second image set are repaired to obtain a third image set. Among them, an image inpainting algorithm based on texture synthesis can be used to repair the second image, that is, by finding similar texture information in other normal regions of the second image, copying and filling it into the defect region to make the texture of the defect region naturally blend with the surrounding area, achieving the repair effect. Finally, a three-dimensional image is constructed based on the third images in the third image set and the first images in the first image set, that is, the three-dimensional spatial form and appearance characteristics of the tank body are restored by using the information of multiple two-dimensional images, thereby obtaining the target three-dimensional image. Among them, through the application of geometric principles such as feature matching, spatial coordinate positioning, and triangulation for images taken at different angles and positions, the positions of each point on the surface of the tank body in the three-dimensional space can be calculated, and then a complete target three-dimensional image can be constructed. For example, the corresponding positions of the same feature point of the tank body in different images can be found in the images taken from different sides. Based on these corresponding relationships and the parameters of the camera during shooting, such as focal length, shooting position, etc., the coordinates of this feature point in the three-dimensional space can be determined through mathematical calculations, and gradually a three-dimensional model of the entire tank body can be constructed, and finally the target three-dimensional image can be obtained.

[0079] It can be seen that by performing defect detection on the first image set and extracting abnormal defect detection results therefrom, it is possible to ensure that only abnormal defects that are significant and may affect the safety and normal operation of the water supply device are concerned, which helps to reduce false alarms and missed detections; by repairing the defect areas in the second image set, the integrity and accuracy of the images can be automatically restored, avoiding the influence of defects on subsequent analysis; by using the repaired images in the third image set and the original images in the first image set to construct three-dimensional images, it can be ensured that incorrect geometric modeling or structural analysis will not occur due to defects during three-dimensional reconstruction, which helps to form more complete and accurate three-dimensional images.

[0080] Among them, the method of repairing the defect areas of each second image in the second image set to obtain the third image set specifically includes the following steps:

[0081] Extract the contour of the defect area of the target image, where the target image is any one in the second image set; determine the contour section and contour truncation points of the defect area contour; perform contour extension processing on the target image according to the contour section and contour truncation points to obtain a reference image; perform correction processing on the extended contour in the reference image to obtain a third image; repeat the method of extracting the contour of the defect area of the target image to performing correction processing on the extended contour in the reference image to obtain a third image until the third image corresponding to each second image is obtained, thus obtaining the third image set.

[0082] Specifically, by calculating the gradient intensity and direction of the pixel points in the second image and using steps such as non-maximum suppression and double-threshold detection, the edges of the objects in the image can be effectively extracted, thereby outlining the contour of the defect area to extract the contour of the defect area of the target image. Then, determine the contour section and contour truncation points of the defect area contour. Among them, the contour section refers to the cross-sectional shape along a certain direction of the defect area contour, which reflects geometric features such as the depth and width of the defect area in this direction, and the contour truncation point refers to the point on the defect area contour where there are obvious turns, breaks or intersections with other important features. The contour section can be determined by selecting different tangent directions along the contour line and then obtaining the pixel information on the cross-section perpendicular to the tangent direction, and then analyzing features such as its gray-scale change and shape. Then, by calculating the curvature of the contour curve, the position where the curvature undergoes a sudden change is determined as the contour truncation point.

[0083] Next, according to the defect morphological characteristics reflected by the contour section and the key positions indicated by the contour truncation points, in accordance with the corresponding geometric rules and the law of image pixel change, the contour of the defect area is extended outward along a suitable direction. For example, if the contour section shows that the defect presents a gradually narrowing trend, then the extension direction can be appropriately carried out along the opposite direction of the narrowing to restore a more complete original shape of the defect, thereby obtaining a reference image. Then, by analyzing the texture, color, shape and other information of the normal image area around the extended contour, the extended contour is adjusted. For example, if the extended contour extends to a position where the texture is significantly mismatched with the surrounding normal area, the extended contour can be corrected by shrinking or adjusting the direction according to the texture trend and characteristics of the surrounding area, so that it is more coordinated and natural with the surrounding area, thereby obtaining a third image.

[0084] Finally, repeat the method of extracting the contour of the defect area of the target image above to the correction process of the extended contour in the reference image to obtain the third image until the third image corresponding to each second image is obtained, and a third image set is obtained.

[0085] It can be seen that by extracting the contour of the defect area and performing extension and correction, the quality of the image is gradually optimized, thereby improving the repair effect, enhancing the accuracy and reliability of image analysis, and finally obtaining a high-quality third image set.

[0086] Among them, the specific steps of correcting the extended contour in the reference image to obtain the third image include:

[0087] Obtain the extension matching degree between the extended contour and the defect area; if the extension matching degree is lower than the preset matching degree, smooth the extension connection in the reference image to obtain the third image.

[0088] Specifically, the curvature difference between the extended contour and the defect area contour at the corresponding position can be calculated, and the extension matching degree can be measured by statistics of indicators such as the average curvature difference and the consistency of the curvature change trend. For example, if the curvature difference is small, the extension matching degree is relatively high; the geometric parameters such as the aspect ratio and area ratio of the two can also be compared. If the geometric parameters are relatively close, the corresponding extension matching degree is high. When the extension matching degree is lower than the preset matching degree, smooth the extension connection in the reference image. For example, perform curve fitting on the connection part between the extended contour and the defect area boundary, and adjust the shape of the connection curve to make it smoother and more fluent, thereby enhancing the fusion degree of the extended part and the entire defect area and obtaining a third image that is more in line with the actual situation.

[0089] It can be seen that by obtaining the extension matching degree and making judgments and corresponding smoothing processing according to the preset matching degree, the quality of the extended contour in the reference image can be further optimized, and the rationality and accuracy of the image can be enhanced.

[0090] The method for determining the abnormal information of the tank body according to the target three-dimensional image may be as follows:

[0091] Among them, the specific steps for determining the state information of the tank body according to the target three-dimensional image include:

[0092] Obtain the target similarity between the target three-dimensional image and the preset three-dimensional image of the tank body; if the target similarity is less than the preset similarity threshold, determine that the abnormal information is that there is an abnormality; if the target similarity is greater than or equal to the preset similarity threshold, determine that the abnormal information is empty.

[0093] Specifically, the target similarity can be calculated by comparing in geometric aspects such as shape, size, and spatial structure. For example, compare the overall length, width, and height dimensions of the tank body in the target three-dimensional image and the preset three-dimensional image, calculate the dimension difference ratio, if the difference ratio is small, the target similarity is high; it is also possible to analyze the surface curvature distribution of the two, and measure the similarity of the surface shape by calculating statistical quantities such as the root mean square of the curvature difference. The smaller the curvature difference, the higher the target similarity. When the target similarity is less than the preset similarity threshold, it indicates that there are relatively significant differences between the actual three-dimensional image of the tank body and the preset three-dimensional image of the normal state, indicating that the tank body has abnormal conditions such as deformation, surface damage, and loosening of the connection parts during actual use, which will in turn have an adverse impact on its functions such as storing heat exchange medium and performing heat exchange, and determine that the state information of the tank body is determined to be an abnormal state, so as to timely remind relevant personnel to conduct further inspections, repairs, etc., to avoid further deterioration of the problem and ensure the normal operation of the water supply device. When the target similarity is greater than or equal to the preset similarity threshold, it indicates that the actually obtained three-dimensional image of the tank body is relatively close to the preset three-dimensional image of the normal state, and basically conforms to the characteristics of the normal state within the acceptable error range, indicating that there are no obvious abnormalities in the current appearance, structure, etc. of the tank body, and it is in a normal working state and can continue to stably perform its functions of storing heat exchange medium and participating in heat exchange. Therefore, determine that the state information of the tank body is in a normal state, and there is no need to take immediate additional intervention measures, but its state changes can still be continuously monitored according to the regular detection cycle.

[0094] It can be seen that by calculating the target similarity between the target three-dimensional image and the preset three-dimensional image and comparing it with the preset similarity threshold to determine the state information of the tank body, it helps to realize the effective monitoring and maintenance management of the tank body in the water supply device.

[0095] After determining the abnormal information, alarm processing can be carried out in combination with the target state information. Specifically:

[0096] The state indicated by the target state information is an abnormal state, and the abnormal information is that there is an abnormality, which indicates that the tank has been subjected to an external impact and needs to be urgently processed. At this time, the alarm information is the alarm information with a higher alarm level, and the remaining states are ordinary alarm information. The alarm information can be set through empirical values or historical data.
