Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to an automatic flip control method for a cable channel ventilation cover. Background Art

[0002] In power systems, cable trenches serve as the primary pathways for cable installation. Proper ventilation and heat dissipation within these trenches are crucial for ensuring safe cable operation. Traditional cable trench ventilation covers are typically fixed or manually opened and closed. This approach lacks flexibility in adapting to varying environmental conditions, making it difficult to effectively and timely adjust ventilation within the trench. Especially during rainy seasons, snowy days, or in high humidity, moisture and debris can easily accumulate within the trench, leading to poor ventilation and compromising cable heat dissipation and service life.

[0003] The existing technology triggers the opening and closing of the ventilation cover by detecting the temperature inside the cable trench, but ignores the influence of accumulation, that is, when the outside is in heavy rain or snow or there are excess impurities in the outside. When the accumulation is thick, it means that there are more external impurities. Even if the temperature rises to a certain extent, the ventilation cover needs to be closed to prevent external substances from entering the cable trench and causing further deterioration of the cable trench. On the contrary, if the accumulation is thin, it means that the external influence is small, so the ventilation cover is opened as much as possible, and there is no need to adjust the ventilation cover frequently. Therefore, this single control strategy often leads to poor ventilation effect or energy waste. In addition, the automatic adjustment system of the ventilation cover in the existing technology usually lacks a detailed flap strategy formulation process, and only performs opening and closing operations based on simple threshold judgments, lacking a detailed analysis and response strategy for ventilation needs in different situations. This may result in the ventilation cover failing to respond in a timely and accurate manner under extreme weather or special working conditions, thereby affecting the ventilation effect inside the cable trench and the safe operation of the cable. Summary of the Invention

[0026] like Figure 1 As shown, a method for automatically flipping a ventilating cover of a cable duct is provided. The method is applied to the ventilating cover of the cable duct, wherein the ventilating cover of the cable duct includes a blocking outer plate and a ventilating inner plate. The method includes:

[0027] S1. Obtaining a first layer thickness on the ventilation inner plate and a first temperature inside the cable trench at a first moment, and determining whether the first layer thickness is greater than a thickness threshold;

[0028] S2. If the thickness of the first laminate is greater than the thickness threshold, obtaining a second moment separated from the first moment by a first preset time period, obtaining a second temperature inside the cable trench at the second moment, obtaining a first motion index based on the first calculation model, the first temperature, and the second temperature, obtaining a first flipping strategy based on the first motion index, and adjusting the position of the blocking outer plate according to the first flipping strategy;

[0029] S3. If the thickness of the first accumulation layer is not higher than the thickness threshold, obtain a third moment that is separated from the first moment by a second preset time period, and obtain the second accumulation layer thickness on the ventilation inner panel and the third temperature inside the cable trench at the third moment, and obtain a flip index based on the second calculation model, the first accumulation layer thickness, and the second accumulation layer thickness. If the flip index exceeds the flip threshold, obtain a second motion index based on the first calculation model, the first temperature, and the third temperature, and obtain a second flip strategy based on the second motion index and adjust the position of the blocking outer panel according to the second flip strategy.

[0030] In this embodiment, it should be noted that this method is applied to cable trench ventilation covers, which are designed as a two-layer structure, consisting of an outer baffle and an inner ventilation panel. The outer baffle is responsible for opening and closing according to the control strategy to regulate the ventilation of the cable trench; the inner ventilation panel serves as part of the ventilation channel between the interior of the cable trench and the external environment. The thickness of the layer on the inner ventilation panel is also an important reference factor in the formulation of the control strategy. In S1, the thickness of the layer on the inner ventilation panel and the temperature inside the cable trench are first monitored in real time. During this process, sensors are used to accurately obtain the first layer thickness of impurities (such as dust and fallen leaves) accumulated on the surface of the inner ventilation panel. Simultaneously, a temperature sensor measures the first temperature inside the cable trench. After obtaining this data, a judgment analysis is performed, the core of which is to compare the first layer thickness with a preset thickness threshold. This thickness threshold is set based on a combination of factors such as the ventilation requirements of the cable trench, safety standards, and the potential impact of the external environment on the cable trench. If the thickness of the first accumulation layer is higher than this threshold, it means that there are a lot of external impurities, which may pose a threat to the internal environment of the cable trench. At this time, a more cautious ventilation strategy needs to be adopted.

[0031] For example, suppose that during a certain test, the first layer thickness measured on the ventilation inner panel is 10 mm, while the preset thickness threshold is 5 mm. At the same time, the first temperature inside the cable trench is 25 degrees Celsius. Because the first layer thickness of 10 mm is higher than the thickness threshold of 5 mm, it is judged that the external environment has a significant potential impact on the cable trench, such as sediment accumulation after a rainstorm or snow cover after a snowstorm. In this case, the ventilation cover will not be simply closed, but the subsequent step S2 will be entered to comprehensively consider temperature changes and layer thickness to formulate a more reasonable ventilation cover closing strategy.

[0032] In S2, when it is determined that the thickness of the first layer on the ventilation inner plate is higher than the preset thickness threshold, it means that the external environment poses a greater potential threat to the cable trench, and a more cautious ventilation strategy needs to be adopted at this time. Therefore, after waiting for a first preset time period, the second temperature inside the cable trench is obtained again at the second moment. This waiting time is to ensure the accuracy of the temperature change and avoid misjudgment due to instantaneous temperature fluctuations. After obtaining the second temperature, a first motion index is calculated based on a pre-set first calculation model, combined with the changes in the first temperature and the second temperature. This first motion index reflects the trend of temperature changes inside the cable trench and the degree of response to the influence of the external environment. Based on this first motion index, a first flip-up strategy will be further formulated to determine the position of the outer plate to balance the ventilation needs and the threats from the external environment. Finally, according to this first flip-up strategy, the outer plate will be driven to move to the corresponding position to ensure the safety and stability of the internal environment of the cable trench.

[0033] For example, suppose that the thickness of the first layer on the ventilation inner plate is measured to be 8 mm at the first moment, which is higher than the thickness threshold of 5 mm, and the first temperature inside the cable trench is 25 degrees Celsius. After waiting for a first preset time period (such as 10 minutes), the temperature inside the cable trench is measured again at the second moment, and the second temperature is 27 degrees Celsius. According to the first calculation model, the first motion index is calculated in combination with the changes in the first temperature and the second temperature. Based on this first motion index, the first flip-up strategy is formulated as "moderate closure is required", and it is decided that the blocking outer plate should be closed to a certain angle to reduce the entry of external impurities. Finally, the blocking outer plate is driven to move to the corresponding position according to the first flip-up strategy, ensuring the safety and stability of the internal environment of the cable trench under the threat of the external environment.

[0034] In S3, if the thickness of the first layer on the ventilated inner panel is determined to be no greater than a preset thickness threshold, the potential impact of the external environment on the cable trench is minimal, and a relatively relaxed ventilation strategy is implemented. After a second preset period of time, the thickness of the layer on the ventilated inner panel and the temperature inside the cable trench are monitored again at a third moment. This waiting period is intended to observe the changing trends of the layer thickness and temperature, allowing for more accurate formulation of a ventilation strategy. At the third moment, the thickness of the second layer on the ventilated inner panel and the third temperature inside the cable trench are obtained. Based on a pre-set second calculation model, the changes in the thickness of the first and second layers, as well as the temperature inside the cable trench, are combined to calculate a ventilation index. This ventilation index reflects the combined ventilation needs and external environmental impacts within the cable trench. A determination is made as to whether this ventilation index exceeds the preset threshold. If so, there is a significant risk of external impact on the interior of the cable trench, and the outer barrier panels need to be closed to ensure safety within the trench. If not, the external impact is minimal, and adequate ventilation is required.

[0035] For example, suppose that at the first moment the thickness of the first layer on the ventilation inner plate is measured to be 3 mm, which is lower than the thickness threshold of 5 mm, and the first temperature inside the cable trench is 22 degrees Celsius. After waiting for a second preset time period (such as 30 minutes), the thickness of the layer on the ventilation inner plate and the temperature inside the cable trench are measured again at the third moment, and the second layer thickness is 4 mm and the third temperature is 24 degrees Celsius. According to the second calculation model, the flip index is calculated in combination with the changes in the first layer thickness, the second layer thickness, and the first and third temperatures. Assuming that this flip index exceeds the preset flip threshold, it means that there is a greater risk of the outside world affecting the inside of the cable trench, so a second flip strategy needs to be formulated. According to this second flip strategy, the outer sealing plate is driven to move to the corresponding position to ensure the ventilation effect of the internal environment of the cable trench and the safe operation of the cable.

[0036] In summary, in the automatic flap control method for cable trench ventilation covers, the outer sealing plate and inner ventilation plate of the double-layer cover structure each perform their respective functions. The outer sealing plate is responsible for flexibly adjusting the degree of opening and closing according to changes in the external environment, while the inner ventilation plate serves as a ventilation channel, and the thickness of the deposits on it also becomes an important basis for judging the impact of the external environment. First, by real-time monitoring the deposit thickness on the inner ventilation plate and the temperature inside the cable trench, the entire method can accurately identify potential threats to the cable trench from the external environment, such as sediment accumulation after heavy rain, snow cover after snowy days, or impurity deposition in the air. Furthermore, by combining preset thickness thresholds and flap thresholds, as well as motion indicators calculated based on temperature changes, the technical solution can intelligently formulate flap strategies that adapt to different situations. These strategies not only ensure the safe closure of the cable trench in severe weather or special working conditions, effectively preventing the intrusion of external harmful substances, but also ensure sufficient ventilation in good weather conditions, which is beneficial to the heat dissipation of the cable and extends the service life. Furthermore, by optimizing the flap strategy formulation process, the technical solution reduces the frequent adjustment of the ventilation cover, thereby reducing energy consumption and maintenance costs.

[0037] like Figure 2 As shown, in one embodiment, obtaining a first flipping strategy according to the motion index and adjusting the position of the blocking outer panel according to the first flipping strategy in S2 includes:

[0038] S21. Obtaining a first reserved gap angle according to a first motion index;

[0039] S22: Obtain a first current position of the blocking outer panel, and obtain a first target position of the blocking outer panel according to the first reserved gap angle, and obtain a first flipping strategy according to the first current position and the first target position;

[0040] S23: driving the blocking outer panel according to the first flipping strategy to place the blocking outer panel in a first target position.

[0041] In this embodiment, it should be noted that, in S21, the first reserved gap angle is calculated based on the first motion index. This first motion index is based on the change in the temperature inside the cable trench between the first moment and the second moment, and is obtained through the first calculation model. It reflects the trend of temperature change inside the cable trench and the degree of response to the influence of the external environment. The first reserved gap angle is determined based on this motion index, which represents the size of the ventilation gap that needs to be retained when the outer panel of the enclosure is closed. This angle is set to ensure the safety inside the cable trench while maintaining ventilation as much as possible to avoid poor ventilation due to excessive closure. The first motion index will be converted into a specific first reserved gap angle according to a preset algorithm or table lookup method, providing a basis for the subsequent formulation of the flip cover strategy.

[0042] For example, suppose that at the first moment, the first temperature inside the cable trench is measured to be 25 degrees Celsius. After waiting for a first preset time period (such as 10 minutes), the second temperature is measured again at the second moment and is 27 degrees Celsius. Based on these two temperature values and the preset first calculation model, the first motion index is calculated as "needs to be moderately closed." Then, based on this motion index and the preset algorithm, the first reserved gap angle is determined to be 30 degrees. This means that when closing the outer baffle plate, a 30-degree ventilation gap needs to be retained to ensure ventilation inside the cable trench.

[0043] In S22, it is necessary to obtain the first current position of the blocking outer panel and calculate the first target position of the blocking outer panel based on the first reserved gap angle. The first current position of the blocking outer panel can be obtained by real-time monitoring by sensors, which reflects the current open and closed state of the blocking outer panel. The first target position is calculated based on the first reserved gap angle and the initial position (or fully open position) of the blocking outer panel. It represents the position that the blocking outer panel should reach after executing the flip strategy. Based on the first current position and the first target position, a specific first flip strategy will be formulated, including parameters such as the flip direction, speed, and acceleration.

[0044] Continuing with the above example, let's assume the outer panel's first current position is fully open (i.e., 0 degrees), and the first reserved gap angle is 30 degrees. Based on these two parameters, the outer panel's first target position is calculated to be 30 degrees. This means that when executing the first flip strategy, the outer panel needs to rotate from 0 degrees to 30 degrees to maintain a 30-degree ventilation gap.

[0045] In S23, the outer blocking plate is driven to the first target position according to the first flapping strategy. This process is carried out jointly by a controller and an actuator. The controller receives the first flapping strategy and converts it into a specific control signal; the actuator, in turn, drives the outer blocking plate to rotate according to the control signal. During execution, parameters such as the position and speed of the outer blocking plate are monitored in real time to ensure that it accurately reaches the first target position. Furthermore, the control signal is fine-tuned based on actual conditions to account for potential interference and errors.

[0046] Continuing with the above example, once the first flap strategy is developed, the controller receives this strategy and converts it into a specific control signal. The actuator then uses this control signal to rotate the outer flap from 0 to 30 degrees. During this process, parameters such as the position and speed of the flap are monitored in real time to ensure that it accurately reaches the 30-degree position. If, for any reason (such as wind or mechanical wear), the flap is unable to reach the target position, the control signal is adjusted to compensate and correct the situation.

[0047] like Figure 3 As shown, in one embodiment, obtaining a second flipping strategy according to the second motion index and adjusting the position of the blocking outer panel according to the second flipping strategy in S3 includes:

[0048] S31, obtaining a second reserved gap angle according to a second motion index;

[0049] S32: Acquire a second current position of the blocking outer panel, and acquire a second target position of the blocking outer panel according to the second reserved gap angle, and acquire a second flipping strategy according to the second current position and the second target position;

[0050] S33: driving the blocking outer panel according to the second flipping strategy to place the blocking outer panel at a second target position.

[0051] In this embodiment, it should be noted that, similarly, in S31, the second reserved gap angle is calculated based on the second motion index. This second motion index is based on the change in the temperature inside the cable trench between the first moment and the third moment, and is obtained through the first calculation model. It reflects the trend of temperature change inside the cable trench and the degree of response to the influence of the external environment. The second reserved gap angle is determined based on this motion index, which represents the size of the ventilation gap that needs to be retained when the outer panel of the enclosure is closed. This angle is set to ensure the safety inside the cable trench while maintaining ventilation as much as possible to avoid poor ventilation due to excessive closure. The second motion index will be converted into a specific second reserved gap angle according to a preset algorithm or table lookup method to provide a basis for the subsequent formulation of the flip cover strategy.

[0052] In S32, the second current position of the blocking outer panel needs to be obtained, and the second target position of the blocking outer panel is calculated based on the second reserved gap angle. The second current position of the blocking outer panel can be monitored in real time by sensors, which reflects the current open and closed state of the blocking outer panel. The second target position is calculated based on the second reserved gap angle and the initial position (or fully open position) of the blocking outer panel. It represents the position that the blocking outer panel should reach after executing the flip strategy. Based on the second current position and the second target position, a specific second flip strategy is formulated, including parameters such as the flip direction, speed, and acceleration.

[0053] In S33, the second flapping strategy is used to drive the outer blocking plate to the second target position. This process is carried out jointly by the controller and actuator. The controller receives the second flapping strategy and converts it into a specific control signal; the actuator, in turn, drives the outer blocking plate to rotate according to the control signal. During execution, parameters such as the position and speed of the outer blocking plate are monitored in real time to ensure that it accurately reaches the second target position. Furthermore, the control signal is fine-tuned based on actual conditions to account for potential interference and errors.

[0054] In one embodiment, the first calculation model in obtaining the first exercise index based on the first calculation model, the first temperature, and the second temperature in S2 is expressed as:

[0055] I1=|T2-T1|·sgn(T2-T1); where,

[0056] I1 is the first motion index, T1 is the first temperature, and T2 is the second temperature.

[0057] In this embodiment, it should be noted that |T2-T1| calculates the absolute value of the temperature difference between the two moments, that is, it does not consider whether the temperature rises or falls, but only focuses on the amplitude of the temperature change. Regardless of whether the temperature rises or falls, the amplitude of the change is an important factor affecting the internal environment of the cable trench. The absolute value operation ensures that regardless of the direction of the temperature change, a positive number can be obtained to represent the amplitude of the change. sgn is a sign function that returns 1 or -1 depending on the positive or negative input value. If the input value is positive, it returns 1; if the input value is negative, it returns -1; if the input value is 0, it usually returns 0. Therefore, sgn(T2-T1) determines the direction of the temperature change, so that the first motion index I1 includes not only the amplitude of the temperature change, but also the direction of the change. This is crucial for formulating a flipping strategy, because temperature increases and decreases may require different adjustments to the flipping.

[0058] By combining absolute value and sign functions, the first calculation model accurately reflects the magnitude and direction of temperature changes within the cable trench. This accuracy is crucial for developing appropriate flap strategies, as different temperature changes may require different flap adjustments. The value of the first motion index, I1, can be directly used to develop flap strategies. For example, if I1 is large and positive (indicating a significant temperature increase), sufficient ventilation space is required to prevent overheating within the cable trench, so the flap may be kept open to promote ventilation and heat dissipation. If I1 is small and non-positive (indicating stable or decreasing temperature), then reserving space for ventilation and heat dissipation may not be necessary.

[0059] In one embodiment, obtaining the first reserved gap angle according to the first motion index in S21 is expressed as:

[0060] in,

[0061] θ1 is the first reserved gap angle, β is the maximum exposure angle, I1 is the first motion index, I b is the effective indicator threshold.

[0062] In this embodiment, it should be noted that the max(0, I1) component ensures that the motion index I1 (i.e., the magnitude and direction of the temperature change) is non-negative after the value is taken. If I1 is negative (indicating a temperature drop), it is set to 0. This is because in this scenario, it represents a temperature drop and generally does not require adjusting the flap to increase ventilation. Therefore, the first reserved gap angle is 0°. If I1 is positive (indicating a temperature increase), the value of I1 is used directly. This is because a temperature increase may require adjustment of the flap to maintain a certain level of ventilation to prevent overheating inside the cable trench. β is the maximum exposure angle, that is, the maximum angle space that can be reserved when the outer panel is closed. This multiplication operation multiplies the motion index I1 (after non-negative processing) by the maximum exposure angle β and divides it by the effective index threshold I b , to obtain a ratio relative to the maximum exposure angle; I b Is the effective index threshold, which is a preset threshold used to set the motion index I1 Normalized to a range of about 1; and when I1 exceeds I b hour, Greater than 1, then Greater than β, Equal to β. Make sure the final angle is not negative; if the previous calculation result is 0 or a positive number, use it directly; if it is negative, take the value of 0 multiple times and finally take 0.

[0063] In one embodiment, the first calculation model in obtaining the second motion index based on the first calculation model, the first temperature, and the third temperature in S3 is expressed as:

[0064] I2=|T3-T1|·sgn(T3-T1); where,

[0065] I2 is the first motion index, T1 is the first temperature, and T3 is the third temperature.

[0066] In this embodiment, it should be noted that, similarly, |T3-T1| calculates the absolute value of the temperature difference between the two moments, i.e., it does not consider whether the temperature rises or falls, but only focuses on the magnitude of the temperature change. Regardless of whether the temperature rises or falls, the magnitude of the change is an important factor affecting the internal environment of the cable trench. The absolute value operation ensures that regardless of the direction of the temperature change, a positive number can be obtained to represent the magnitude of the change. sgn is a sign function that returns 1 or -1 depending on the positive or negative input value. If the input value is positive, it returns 1; if the input value is negative, it returns -1; if the input value is 0, it usually returns 0. Therefore, sgn(T3-T1) determines the direction of the temperature change, so that the first motion index I2 includes not only the magnitude of the temperature change, but also the direction of the change. This is crucial for formulating a flipping strategy, because temperature increases and decreases may require different adjustments to the flipping.

[0067] By combining absolute value and sign functions, the first calculation model can accurately reflect the magnitude and direction of temperature changes inside the cable trench; this accuracy is crucial for developing appropriate flap strategies, as different temperature changes may require different flap adjustments. The value of the second motion index I2 can be directly used to develop flap strategies. For example, if I2 is large and positive (indicating a significant temperature increase), a certain amount of ventilation space is needed to prevent overheating inside the cable trench, so the flap may be kept open to promote ventilation and heat dissipation. If I2 is small and non-positive (indicating that the temperature is stable or decreasing), then there may be no need to reserve space to ensure ventilation and heat dissipation.

[0068] In one embodiment, obtaining the second reserved gap angle according to the second motion indicator in S31 includes:

[0069] in,

[0070] θ2 is the second reserved gap angle, β is the maximum exposure angle, I2 is the second motion index, I b is the effective indicator threshold.

[0071] In this embodiment, it should be noted that, similarly, the max(0, I2) portion ensures that the motion index I2 (i.e., the magnitude and direction of the temperature change) is non-negative after the value is taken. If I2 is negative (indicating a temperature drop), 0 is used. This is because, in this scenario, it represents a temperature drop and generally does not require adjustment of the flap to increase ventilation. Therefore, the first reserved gap angle is 0°. If I2 is positive (indicating a temperature increase), the value of I2 is used directly. This is because a temperature increase may require adjustment of the flap to maintain a certain level of ventilation to prevent overheating inside the cable trench. β is the maximum exposure angle, that is, the maximum angle space that can be reserved when the outer panel is closed. This multiplication operation multiplies the motion index I2 (after non-negative processing) by the maximum exposure angle β and divides it by the effective index threshold I b , to obtain a ratio relative to the maximum exposure angle; I b Is the effective index threshold, which is a preset threshold used to set the motion index I2 Normalized to a range of about 1; and when I2 exceeds I b hour, Greater than 1, then Greater than β, Equal to β. Make sure the final angle is not negative; if the previous calculation result is 0 or a positive number, use it directly; if it is negative, take the value of 0 multiple times and finally take 0.

[0072] like Figure 4 As shown, in one embodiment, obtaining the flip index based on the second calculation model, the first build-up thickness, and the second build-up thickness in S3 includes:

[0073] S34, obtaining detection areas of the first stacked thickness and the second stacked thickness, and obtaining area coefficients according to the detection areas;

[0074] S35 , obtaining a flip index based on the second calculation model, the area coefficient, the first buildup thickness, and the second buildup thickness.

[0075] In this embodiment, it should be noted that in S34, the first focus is on the detection area of the first lamination thickness and the second lamination thickness. This is because the lamination on the ventilation inner plate may not be evenly distributed, and the lamination thickness in different areas may be different. Therefore, it is necessary to clarify the detection area of the lamination thickness in order to more accurately evaluate the impact of the external environment on the cable trench. The detection area can be divided according to the actual structure and layout of the ventilation inner plate, for example, it can be divided into a central area, an edge area, etc. After determining the detection area, the next step is to obtain the regional coefficient based on the detection area. The regional coefficient is a weighting factor used to reflect the degree of influence of the lamination thickness in different areas on the wind flow of the cable trench. Generally speaking, if the lamination thickness in a certain area has a greater impact on the wind flow of the cable trench, then the regional coefficient of the area will be correspondingly larger. The specific value of the regional coefficient can be determined based on actual experience and experimental data to ensure that it can accurately reflect the influence of the lamination thickness in different areas on ventilation.

[0076] In S35, the flap index is obtained using the second calculation model, the area coefficient, the first buildup thickness, and the second buildup thickness. The second calculation model is a pre-set mathematical model that comprehensively considers changes in buildup thickness, the area coefficient, and possible other factors (such as temperature changes) to calculate a comprehensive index that reflects the cable channel's airflow requirements and the impact of the external environment, namely the flap index. The magnitude and changing trend of this index directly determine whether the position of the outer baffle plate needs to be adjusted.

[0077] For example, suppose at the first moment, the thickness of the first layer of the ventilation inner panel in the center is measured to be 3 mm, and the thickness of the first layer in the edge is 2 mm. At the third moment, the second layer thickness is measured again, and it is 4 mm in the center and 3 mm in the edge. At the same time, based on practical experience and experimental data, the area coefficient for the center is determined to be 0.7, and the area coefficient for the edge is 0.3. These data can then be substituted into the second calculation model to calculate the flap index. This flap index comprehensively considers the changes in the thickness of the layers in the center and edge areas, as well as their varying degrees of impact on the airflow of the cable channel, resulting in a comprehensive indicator that accurately reflects the current ventilation needs and the influence of the external environment.

[0078] In one embodiment, the second calculation model in obtaining the flip index based on the second calculation model, the area coefficient, the first build-up thickness, and the second build-up thickness in S35 is expressed as:

[0079] I f =α·exp(D2-D1); where

[0080] I f is the flip index, α is the area coefficient, D2 is the thickness of the second layer, and D1 is the thickness of the first layer.

[0081] In this embodiment, it should be noted that the regional coefficient α is a weighting factor used to reflect the degree of influence of the thickness of the lamination in different detection areas on the ventilation of the cable channel. According to the actual structure and layout of the ventilation inner plate, the influence of the lamination in different areas (such as the central area and the edge area) on ventilation may be different. The value of α is based on actual experience and experimental data to ensure that the influence of the lamination thickness in each area on ventilation is accurately reflected. Lamination thickness difference (D2-D1): D2 and D1 are the lamination thicknesses measured at the third moment and the first moment respectively. (D2-D1) represents the change in lamination thickness over a period of time. A positive value indicates that the lamination is thickening, and a negative value indicates that the lamination is thinning. Exponential function exp(D2-D1): The exponential function is used to amplify or reduce the influence of the change in lamination thickness. When (D2-D1) is positive and large, exp(D2-D1) will increase rapidly, indicating that the lamination is thickening rapidly. When (D2-D1) is negative or small, exp(D2-D1) will be close to or less than 1, indicating that the lamination is thinning or not changing much. Flip indicator I f It is the product of the regional coefficient α and the exponential function exp(D2-D1). It comprehensively considers the change in layer thickness and the degree of influence of different regions.

[0082] In one embodiment, S3 further includes: if the flip index does not exceed the flip threshold, canceling the adjustment of the blocking outer panel position.

[0083] In the present embodiment, it should be noted that the flap index (this index may represent the opening and closing degree, speed or other relevant parameters of the flap) will be monitored in real time and compared with the preset flap threshold; if the monitored flap index does not reach or exceed the preset flap threshold, it means that the state of the flap does not need to be adjusted or its change is not enough to trigger the adjustment mechanism, then a cancellation operation will be performed, and the position of the outer blocking plate will not be adjusted, and its current state will be kept unchanged to avoid unnecessary actions or potential misoperations. For example, in an automatic door, if the opening angle of the door flap is very small and does not reach the degree to which the outer door baffle needs to be adjusted, the baffle position will be maintained unchanged to ensure stability and efficiency.
