Description

Technical Field

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

[0002] In the power system, the cable trench is the main channel for laying cables. The ventilation and heat dissipation of the internal environment are crucial to ensure the safe operation of the cables. Traditional cable trench ventilation covers are usually fixed or manually opened and closed. This method lacks flexibility in dealing with different environmental conditions and it is difficult to adjust the ventilation conditions inside the cable trench in a timely and effective manner. Especially in rainy seasons, snowy days or environments with high humidity, water vapor or debris easily accumulates inside the cable trench, resulting in poor ventilation, which in turn affects the heat dissipation effect and service life of the cable.

[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 the 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 impurities in the outside world. Even if the temperature rises to a certain extent, the ventilation cover needs to be closed to prevent foreign 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 outside impact is small, then 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 cause the ventilation cover to fail 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

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[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 higher than a thickness threshold;

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

[0029] S3. If the thickness of the first 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 layer thickness on the ventilation inner panel and the third temperature inside the cable trench at the third moment, and obtain a flap index based on the second calculation model, the first layer thickness and the second layer thickness. If the flap index exceeds the flap threshold, obtain a second motion index based on the first calculation model, the first temperature and the third temperature, obtain a second flap strategy based on the second motion index, and adjust the position of the blocking outer panel according to the second flap strategy.

[0030] In this embodiment, it should be noted that the method is applied to the cable trench ventilation cover, wherein the cable trench ventilation cover is designed as a double-layer structure, including an outer sealing outer plate and an inner ventilation inner plate. The outer sealing plate is responsible for opening and closing according to the control strategy to adjust the ventilation state of the cable trench; while the ventilation inner plate is part of the ventilation channel between the inside of the cable trench and the external environment, and the thickness of the layers on it is also an important reference factor for the formulation of the control strategy. In S1, it is first necessary to monitor the thickness of the layers on the ventilation inner plate of the cable trench and the temperature inside the cable trench in real time at the first moment. In this process, the sensor device is used to accurately obtain the first layer thickness of the impurity layer (such as dust, fallen leaves, etc.) accumulated on the surface of the ventilation inner plate, and at the same time, the first temperature inside the cable trench is measured by the temperature sensor. After obtaining these data, judgment and analysis are performed immediately, and the core is to compare the first layer thickness with the preset thickness threshold. This thickness threshold is set comprehensively based on factors such as the ventilation requirements of the cable trench, safety standards, and the possible impact of the external environment on the cable trench. If the thickness of the first layer is higher than this threshold, it means that there are too many 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 in a certain test, the first layer thickness on the ventilation inner plate is measured to be 10 mm at the first moment, while the preset thickness threshold is 5 mm. At the same time, the first temperature inside the cable trench is 25 degrees Celsius. Since 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 greater potential impact on the cable trench, which may be mud and sand accumulation after heavy rain or snow cover after windy and snowy weather. In this case, it is not necessary to simply close the ventilation cover, but to enter the subsequent S2 to comprehensively consider the temperature change and layer thickness to formulate a more reasonable strategy for closing the ventilation cover.

[0032] In S2, when it is judged 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. According to this first motion index, a first flap strategy will be further formulated to determine the position of the blocking outer plate to balance the ventilation needs and the threats of the external environment. Finally, according to this first flap strategy, the blocking 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-cover strategy is formulated as "need to be closed moderately", 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-cover strategy, ensuring the safety and stability of the internal environment of the cable trench under the threat of the external environment.

[0034] In S3, when it is judged that the thickness of the first accumulation layer on the ventilation inner plate is not higher than the preset thickness threshold, it means that the potential impact of the external environment on the cable trench is small, and a relatively loose ventilation strategy will be adopted at this time. After waiting for a second preset time period, the accumulation layer thickness on the ventilation inner plate and the temperature inside the cable trench will be monitored again at the third moment. This waiting time is to observe the change trend of the accumulation layer thickness and temperature, so as to formulate a flap strategy more accurately. At the third moment, the second accumulation layer thickness on the ventilation inner plate and the third temperature inside the cable trench will be obtained, and based on a pre-set second calculation model, combined with the change of the first accumulation layer thickness and the second accumulation layer thickness, and the temperature information inside the cable trench, a flap index is calculated. This flap index reflects the comprehensive situation of the ventilation demand inside the cable trench and the impact of the external environment. It will be judged whether this flap index exceeds the preset flap threshold. If it exceeds, it means that there is a greater risk of the outside world affecting the inside of the cable trench, so it is necessary to close the outer plate to meet the safety needs inside the cable trench; if it does not exceed, it means that the outside impact is small and sufficient ventilation needs to be ensured.

[0035] For example, suppose that at the first moment the thickness of the first layer on the ventilated 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 ventilated 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 flap 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 flap index exceeds the preset flap threshold, it means that there is a greater risk of the outside world affecting the inside of the cable trench, so a second flap strategy needs to be formulated. According to this second flap 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 of the ventilation cover of the entire cable trench, the outer sealing plate and the ventilation inner plate in the double-layer cover structure each have their own 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 ventilation inner plate serves as a ventilation channel, and the thickness of the layers on it also becomes an important basis for judging the impact of the external environment. First, the entire method can accurately capture the potential threats of the external environment to the cable trench by real-time monitoring the thickness of the layers on the ventilation inner plate and the temperature inside the cable trench, such as mud and sand accumulation after heavy rain, snow cover after snowy days, or impurity deposition in the air. Further, combined with the preset thickness threshold and flap threshold, as well as the motion index calculated according to the temperature change, 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 bad weather or special working conditions, effectively prevent the invasion of harmful substances from the outside, but also ensure sufficient ventilation under good weather conditions, which is beneficial to the heat dissipation of the cable and prolonging the service life. Further, the technical solution also reduces the frequent adjustment of the ventilation cover by optimizing the formulation process of the flap strategy, 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, obtaining a first current position of the blocking outer panel, and obtaining a first target position of the blocking outer panel according to the first reserved gap angle, and obtaining a first flipping strategy according to the first current position and the first target position;

[0040] S23, driving the blocking outer plate according to the first flipping strategy to place the blocking outer plate at 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 is closed. This angle is set to ensure the safety of the inside of 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 to provide a basis for the subsequent formulation of the flip cover strategy.

[0042] For example, suppose that the first temperature inside the cable trench is measured to be 25 degrees Celsius at the first moment, and after waiting for a first preset time period (such as 10 minutes), the second temperature is measured again at the second moment to be 27 degrees Celsius. Based on these two temperature values ​​and the preset first calculation model, the first motion index is calculated to be "need 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 ventilation gap of 30 degrees needs to be retained to ensure the ventilation effect 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 according to the first reserved gap angle. The first current position of the blocking outer panel can be obtained by real-time monitoring by the sensor, 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, which 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, assume that the first current position of the blocking outer panel is fully open (i.e., 0 degree position), and the first reserved gap angle is 30 degrees. Then, based on these two parameters, the first target position of the blocking outer panel is calculated to be 30 degrees. This means that when executing the first flip strategy, the blocking outer panel needs to rotate from the 0 degree position to the 30 degree position to retain a 30 degree ventilation gap.

[0045] In S23, the blocking outer plate is driven to move to the first target position according to the first flap strategy. This process needs to be completed by the controller and the actuator. The controller is responsible for receiving the first flap strategy and converting it into a specific control signal; the actuator is responsible for driving the blocking outer plate to rotate according to the control signal. During the execution process, the position and speed of the blocking outer plate and other parameters will be monitored in real time to ensure that it can accurately reach the first target position. At the same time, the control signal will be fine-tuned according to the actual situation to deal with possible interference and errors.

[0046] Continuing with the above example, when the first flap strategy is formulated, the controller will receive this strategy and convert it into a specific control signal. Then, the actuator will drive the outer baffle plate to rotate from the 0-degree position to the 30-degree position according to the control signal. During this process, the position and speed of the outer baffle plate and other parameters will be monitored in real time to ensure that it can accurately reach the 30-degree position. If the outer baffle plate cannot accurately reach the target position for some reason (such as wind force or mechanical wear), the control signal will be adjusted in time to compensate and correct it.

[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, obtaining a second current position of the blocking outer panel, and obtaining a second target position of the blocking outer panel according to the second reserved gap angle, and obtaining a second flipping strategy according to the second current position and the second target position;

[0050] S33, driving the blocking outer plate according to the second flipping strategy to place the blocking outer plate 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 is closed. This angle is set to ensure the safety of the inside of 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, it is necessary to obtain the second current position of the blocking outer panel, and calculate the second target position of the blocking outer panel according to the second reserved gap angle. The second current position of the blocking outer panel can be obtained by real-time monitoring by the sensor, 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, which represents the position that the blocking outer panel should reach after executing the flip strategy. A specific second flip strategy will be formulated based on the second current position and the second target position, including parameters such as the flip direction, speed, and acceleration.

[0053] In S33, the blocking outer plate is driven to move to the second target position according to the second flap strategy. This process needs to be completed by the controller and the actuator. The controller is responsible for receiving the second flap strategy and converting it into a specific control signal; the actuator is responsible for driving the blocking outer plate to rotate according to the control signal. During the execution process, the position and speed of the blocking outer plate and other parameters will be monitored in real time to ensure that it can accurately reach the second target position. At the same time, the control signal will be fine-tuned according to the actual situation to deal with possible interference and errors.

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

[0055] I 1 =|T 2 -T 1 |·sgn(T 2 -T 1 );in,

[0056] I 1 is the first motion index, T 1 is the first temperature, T 2 is the second temperature.

[0057] In this embodiment, it should be noted that |T 2 -T 1 |Calculate the absolute value of the temperature difference between two moments, that is, do not consider whether the temperature rises or falls, only focus on the magnitude of the temperature change; whether the temperature rises or falls, the magnitude of its change is an important factor affecting the internal environment of the cable trench; the absolute value operation ensures that no matter what the direction of the temperature change is, a positive number can be obtained to represent the magnitude of this change. sgn is a sign function, which 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(T 2 -T 1 ) determines the direction of temperature change so that the first motion index I 1 Including not only the magnitude of the temperature change but also the direction of the change is critical for developing a flip strategy, as rising and falling temperatures may require different adjustments to the flip.

[0058] By combining the 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. 1 The value of can be used directly to formulate the flip strategy. For example, if I 1If the value is large and positive (indicating a significant temperature rise), a certain amount of ventilation space needs to be ensured to prevent overheating inside the cable trench, so the flap may be kept open to promote ventilation and heat dissipation; if I 1 If it is small and not positive (indicating that the temperature is stable or decreasing), it may not be necessary to reserve space to ensure ventilation and heat dissipation.

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

[0060] in,

[0061] θ 1 is the first reserved gap angle, β is the maximum exposure angle, I 1 is the first motion index, I b is the effective indicator threshold.

[0062] In this embodiment, it should be noted that max(0,I 1 ) This part ensures that the movement index I 1 (i.e. the magnitude and direction of temperature change) after taking the value, max(0,I 1 ) is a non-negative number; if I 1 If it is negative (indicating a drop in temperature), it is set to 0, because in this scenario, it means that the temperature has dropped, and it is usually not necessary to increase ventilation by adjusting the flap, so the first reserved gap angle is 0°. 1 If it is positive (indicating a temperature rise), I is used directly. 1 As the temperature rises it may be necessary to adjust the flap to maintain a certain amount of ventilation to prevent overheating inside the cable trench. β is the maximum exposure angle, that is, the maximum angle space that the outer panel can leave when closing. This multiplication operation converts the motion index I 1 (After non-negative processing) multiplied by the maximum exposure angle β and divided 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 convert the motion index I 1 of Normalized to a range of about 1; and when I 1 More than I b hour, If greater than 1, 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] I 2 =|T 3 -T 1 |·sgn(T 3 -T 1 );in,

[0065] I 2 is the first motion index, T 1 is the first temperature, T 3 is the third temperature.

[0066] In this embodiment, it should be noted that, similarly, |T 3 -T 1 |Calculate the absolute value of the temperature difference between two moments, that is, do not consider whether the temperature rises or falls, only focus on the magnitude of the temperature change; whether the temperature rises or falls, the magnitude of its change is an important factor affecting the internal environment of the cable trench; the absolute value operation ensures that no matter what the direction of the temperature change is, a positive number can be obtained to represent the magnitude of this change. sgn is a sign function, which 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(T 3 -T 1 ) determines the direction of temperature change so that the first motion index I 2 Including not only the magnitude of the temperature change but also the direction of the change is critical for developing a flip strategy, as rising and falling temperatures may require different adjustments to the flip.

[0067] By combining the absolute value and sign functions, the first calculation model can accurately reflect the magnitude and direction of the temperature change inside the cable trench; this accuracy is crucial for developing appropriate flap strategies, because different temperature changes may require different flap adjustments. 2 The value of can be used directly to formulate the flip strategy. For example, if I 2 If the value is large and positive (indicating a significant temperature rise), a certain amount of ventilation space needs to be ensured to prevent overheating inside the cable trench, so the flap may be kept open to promote ventilation and heat dissipation; if I 2 If it is small and not positive (indicating that the temperature is stable or decreasing), it may not be necessary to reserve space to ensure ventilation and heat dissipation.

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

[0069] in,

[0070] θ 2 is the second reserved gap angle, β is the maximum exposure angle, I 2 is the second motion index, I b is the effective indicator threshold.

[0071] In this embodiment, it should be noted that, similarly, max(0,I 2 ) This part ensures that the movement index I 2 (i.e. the magnitude and direction of temperature change) after taking the value, max(0,I 2 ) is a non-negative number; if I 2 If it is negative (indicating a drop in temperature), it is set to 0, because in this scenario, it means that the temperature has dropped, and it is usually not necessary to increase ventilation by adjusting the flap, so the first reserved gap angle is 0°. 2 If it is positive (indicating a temperature rise), I is used directly. 2 As the temperature rises it may be necessary to adjust the flap to maintain a certain amount of ventilation to prevent overheating inside the cable trench. β is the maximum exposure angle, that is, the maximum angle space that the outer panel can leave when closing. This multiplication operation converts the motion index I 2 (After non-negative processing) multiplied by the maximum exposure angle β and divided 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 convert the motion index I 2 of Normalized to a range of about 1; and when I 2 More than I b hour, If greater than 1, 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 layer thickness and the second layer 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 build-up thickness, and the second build-up thickness.

[0075] In this embodiment, it should be noted that in S34, the first focus is on the detection area of ​​the first layer thickness and the second layer thickness. This is because the layers on the ventilation inner plate may not be evenly distributed, and the layer thickness in different areas may be different. Therefore, it is necessary to clarify the detection area of ​​the layer 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, and the like. 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 layer thickness in different areas on the wind flow of the cable trench. Generally speaking, if the layer 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 impact of the layer thickness in different areas on ventilation.

[0076] In S35, the flap index is obtained using the second calculation model, the area coefficient, the first layer thickness and the second layer thickness. The second calculation model is a pre-set mathematical model, which is used to comprehensively consider the change of layer thickness, the area coefficient and possible other factors (such as temperature change, etc.) to calculate a comprehensive index that can reflect the ventilation demand of the cable channel and the influence of the external environment, that is, the flap index. The size and change trend of this index will directly determine whether the position of the outer baffle plate needs to be adjusted.

[0077] For example, suppose that at the first moment, the thickness of the first layer in the center area of ​​the ventilation inner plate is measured to be 3 mm, and the thickness of the first layer in the edge area is 2 mm; at the third moment, it is measured again, and the thickness of the second layer in the center area is 4 mm, and the thickness of the second layer in the edge area is 3 mm. At the same time, based on actual experience and experimental data, the regional coefficient of the center area is determined to be 0.7, and the regional coefficient of the edge area is 0.3. Then, these data can be substituted into the second calculation model to calculate the flap index. This flap index will comprehensively consider the changes in the thickness of the layers in the center area and the edge area, as well as their different degrees of influence on the wind of the cable channel, so as to obtain a comprehensive index that can accurately reflect the current ventilation needs and the impact 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 buildup thickness and the second buildup thickness in S35 is expressed as:

[0079] I f =α·exp(D 2 -D 1 );in,

[0080] I fis the flip index, α is the area coefficient, D 2 is the thickness of the second layer, D 1 is the first layer thickness.

[0081] In this embodiment, it should be noted that the regional coefficient α is a weight factor used to reflect the degree of influence of the thickness of the layers 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 layers 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 thickness of the layers in each area on ventilation is accurately reflected. The difference in layer thickness (D 2 -D 1 ): D 2 and D 1 are the layer thickness measured at the third moment and the first moment respectively. (D 2 -D 1 ) represents the change in the thickness of the layer over a period of time. A positive value indicates that the layer is thickening, and a negative value indicates that the layer is thinning. The exponential function exp(D 2 -D 1 ): Exponential function is used to amplify or reduce the effect of layer thickness changes. 2 -D 1 ) is positive and large, exp(D 2 -D 1 ) will increase rapidly, indicating that the accumulation layer is rapidly thickening. 2 -D 1 ) is negative or small, exp(D 2 -D 1 ) will be close to or less than 1, indicating that the layer is thinning or has little change. f is the area coefficient α and the exponential function exp(D 2 -D 1 ). It comprehensively considers the variation of layer thickness and the 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 panel 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 where the outer baffle of the door needs to be adjusted, the baffle position will be maintained unchanged to ensure stability and efficiency.
