Description

Technical Field

[0001] This application belongs to the field of cable protection technology, and in particular relates to a method for optimizing cable protection structure, cable and equipment. Background Technology

[0002] A cable is a transmission medium consisting of a conductor (such as copper or aluminum), an insulation layer, a sheath, necessary reinforcing layers, and covering materials, used to transmit electricity, signals, or data. Cable protection structures are protective sheaths (e.g., flame-retardant sheath materials, aluminum tape sheaths, etc.) installed to protect cables from mechanical damage, environmental corrosion, electromagnetic interference, and animal or human-caused damage during laying, operation, and maintenance.

[0003] In related technologies, cable protection structures typically employ higher protection levels in high-load cable laying sections to reduce the risk of damage from external forces or corrosion. However, as the protection level of the cable protection structure increases, the load it bears also increases, leading to a greater stress concentration. To mitigate the impact of stress concentration on cable operation, the protection level is increased when the stress in the cable protection structure equals a predetermined fixed stress. However, this optimization scheme is not precise enough, reducing the reliability of cable protection. Summary of the Invention

[0004] This application provides a method, cable, and equipment for optimizing cable protection structure, which can solve the problem that the optimization scheme for protection level in related technologies is not accurate enough, thus reducing the reliability of cable protection.

[0005] In a first aspect, embodiments of this application provide a method for optimizing cable protection structures, including: When optimizing the cable protection structure for the first working condition according to the preset protection level, if the obtained detection stress data of the cable protection structure exceeds the preset stress data, a stress bearing coefficient of the cable protection structure is generated based on the detection stress data and the preset protection level; wherein, the stress bearing coefficient is used to indicate the stress borne by each section of the cable protection structure under the current conditions, and the detection stress data is used to reflect the statistical value of the actual stress of the cable protection structure within the target monitoring time. Based on the stress bearing capacity coefficient of the cable protection structure, the preset stress data, and the target data, permissible change data is generated; wherein, the target data is used to indicate that the adjustment of the protection level is related to stress variation; the permissible change data is used to indicate the stress warning value corresponding to the adjustment of the protection level; the permissible change data is the critical stress that triggers the adjustment of the protection level, and it is dynamically changing; If the target stress data of the cable protection structure meets the conditions for the allowable change data, the protection level of the cable protection structure is changed from the preset protection level to the target protection level based on the actual stress variation trend data of the cable protection structure; wherein, the target protection level is higher than the preset protection level, and the preset protection level is generated based on the stress bearing coefficient and the preset stress data; the variation trend data is used to indicate the amount of change of actual stress per minute between the current real-time stress and the real-time stress at the previous moment.

[0006] The technical solutions described in this application embodiment have at least the following technical effects: The cable protection structure optimization method provided in this application, when optimizing the cable protection structure for a first operating condition according to a preset protection level, generates a stress bearing capacity factor for the cable protection structure based on the detected stress data and the preset protection level when the detected stress data exceeds the preset stress data. The stress bearing capacity factor indicates the stress borne by each segment of the cable protection structure under current conditions, and the detected stress data reflects the statistical value of the actual stress of the cable protection structure within the target monitoring period. Allowable change data is generated based on the stress bearing capacity factor, the preset stress data, and the target data. The target data indicates that the adjustment of the protection level is related to stress changes. When the target stress data of the cable protection structure meets the conditions for allowable change data, the protection level of the cable protection structure is changed from the preset protection level to the target protection level based on the actual stress change trend data of the cable protection structure. The target protection level is higher than the preset protection level, which is generated based on the stress bearing capacity factor and the preset stress data. This application reflects the current load condition through current stress detection data. Under heavy loads, the dynamic calculation of the current stress bearing capacity coefficient allows for data changes, enabling different stress warning values ​​in different operating scenarios (such as different load types). This allows the cable protection system to set appropriate stress warning values ​​for different scenarios, rather than using fixed, predetermined stress values ​​for protection level adjustments as in related technologies. Furthermore, adjusting the protection level based on actual stress variation trends allows for precise changes, reducing optimization delays and inaccuracies in protection level optimization, thus improving the reliability of cable protection.

[0007] In one possible implementation of the first aspect, before generating permissible change data based on the stress bearing capacity coefficient of the cable protection structure, the preset stress data, and the target data, the method further includes: Obtain the preset stress information of the cable protection structure; wherein, the preset stress information is used to reflect the absolute upper limit stress of the cable protection structure; The preset stress data is obtained based on the preset stress information and preset margin; wherein, the preset margin is a safety buffer ratio or value set in advance based on the stress tolerance capacity of the cable protection structure, and the preset margin is used to reserve stress redundancy space for uncertainties in actual working conditions.

[0008] In one possible implementation of the first aspect, generating permissible change data based on the stress bearing capacity coefficient of the cable protection structure, the preset stress data, and the target data includes: Obtain the stress that each segment length can withstand corresponding to the preset stress data; The difference data is obtained based on the stress that each segment length can withstand corresponding to the preset stress data and the stress bearing coefficient of the cable protection structure; wherein, the difference data is used to reflect the difference between the stress that each segment length corresponding to the preset stress data can withstand and the stress that each segment length of the cable protection structure can withstand under the current conditions. Based on the difference data and the target data, the allowed change data is generated.

[0009] In one possible implementation of the first aspect, generating the permissible change data based on the difference data and the target data includes: Determine the minimum parameter change value; where the minimum parameter change value is used to indicate the minimum change value for the thickness of the protective structure; Based on the difference data and the minimum parameter change value, the minimum number of necessary changes is obtained; The allowed change data is obtained based on the minimum necessary number of changes, the minimum parameter change value, and the lead time coefficient; wherein, the lead time coefficient is used to indicate the advance trigger margin that needs to be reserved in the difference data.

[0010] In one possible implementation of the first aspect, the step of changing the protection level of the cable protection structure from the preset protection level to the target protection level based on the actual stress variation trend data of the cable protection structure, when the target stress data of the cable protection structure meets the conditions of the permissible change data, includes: If the target stress data of the cable protection structure meets the conditions for the allowable change data, protection level change data is generated based on the actual stress variation trend data of the cable protection structure. Based on the protection level change data, the protection level of the cable protection structure is changed from the preset protection level to the target protection level.

[0011] In one possible implementation of the first aspect, the step of generating protection level change data based on the actual stress variation trend data of the cable protection structure, when the target stress data of the cable protection structure meets the conditions of the permissible change data, includes: If the target stress data of the cable protection structure meets the conditions for the allowable change data, the protection level change data is generated based on the actual stress variation trend data and response coefficient of the cable protection structure.

[0012] In one possible implementation of the first aspect, the step of generating the protection level change data based on the actual stress variation trend data and response coefficient of the cable protection structure, provided that the target stress data of the cable protection structure meets the conditions for the permissible change data, includes: Based on the difference data and the total capacity that needs to be increased, the first change data is generated; Based on the actual stress variation trend data of the cable protection structure and the response coefficient, second change data is generated; The protection level change data is generated based on the first change data and the second change data.

[0013] In one possible implementation of the first aspect, the preset protection level change is a change in the thickness of the protective layer.

The target protection level is higher than the preset protection level, and the preset protection level is generated based on the stress bearing capacity coefficient and the preset stress data. The variation trend data indicates the change in actual stress per minute between the current real-time stress and the previous real-time stress.

[0026] The following section discusses the problem that the protection level optimization scheme is not accurate enough, which reduces the reliability of cable protection.

[0027] When the stress in the cable protection structure exceeds the preset stress (e.g., 50 MPa), the protection level of the cable protection structure is changed from the current protection level A (e.g., multiple low-stiffness flexible protective sleeves, for example, 2, or a protective layer thickness of 5 mm) to a higher protection level C (e.g., multiple high-stiffness protective sleeves, for example, 3, or a protective layer thickness of 8 mm). As the protection level of the cable protection structure increases, the structure no longer directly bears the load. Instead, it absorbs and disperses external forces through the elastic deformation of its low-stiffness flexible protection. Some of the load is dissipated by the deformation of the buffer material, reducing the load-bearing capacity and stress concentration of the protection structure, and thus decreasing the stress in the cable protection structure. However, since stress transfer and structural deformation require time, during the level change process, if the stress stops increasing with the protection level change, the protection level may still be increasing. Even if the protection level stops increasing, the stress will not continue to increase, resulting in the protection level change not matching the stress change in a timely manner. This leads to an inaccurate protection level optimization scheme and reduces the reliability of the cable protection.

[0028] To address the aforementioned issues, embodiments of this application provide a method for optimizing cable protection structures, as well as a cable and equipment.

[0029] In this method, when optimizing the cable protection structure for the first operating condition based on a preset protection level, if the detected stress data of the cable protection structure exceeds the preset stress data, a stress bearing capacity factor for the cable protection structure is generated based on the detected stress data and the preset protection level. The stress bearing capacity factor indicates the stress borne by each segment of the cable protection structure under current conditions, and the detected stress data reflects the statistical value of the actual stress of the cable protection structure within the target monitoring period. Based on the stress bearing capacity factor, preset stress data, and target data, permissible change data is generated. The target data indicates that adjustments to the protection level are related to stress variations. If the target stress data of the cable protection structure meets the conditions for permissible change data, the protection level of the cable protection structure is changed from the preset protection level to the target protection level based on the actual stress variation trend data of the cable protection structure. The target protection level is higher than the preset protection level, which is generated based on the stress bearing capacity factor and the preset stress data. This application reflects the current load condition through current stress detection data. Under heavy loads, the dynamic calculation of the current stress bearing capacity coefficient allows for data changes, enabling different stress warning values ​​in different operating scenarios (such as different load types). This allows the cable protection system to set appropriate stress warning values ​​for different scenarios, rather than using fixed, predetermined stress values ​​for protection level adjustments as in related technologies. Furthermore, adjusting the protection level based on actual stress variation trends allows for precise changes, reducing optimization delays and inaccuracies in protection level optimization, thus improving the reliability of cable protection.

[0030] The cable protection structure optimization method provided in this application embodiment can be applied to electronic devices. In this case, the electronic device is the executing subject of the cable protection structure optimization method provided in this application embodiment. This application embodiment does not impose any restrictions on the specific type of electronic device.

[0031] For example, electronic devices can be microcontrollers, mobile phones, tablets, laptops, ultra-mobile personal computers (UMPCs), netbooks, desktop computers, computing devices, or computers connected to wireless modems, laptops, handheld communication devices, handheld computing devices, etc.

[0032] To better understand the cable protection structure optimization method provided in the embodiments of this application, the specific implementation process of the cable protection structure optimization method provided in the embodiments of this application will be described by way of example below.

[0033] Figure 1A schematic flowchart of a cable protection structure optimization method provided in an embodiment of this application is shown. The cable protection structure optimization method includes: S100, when optimizing the cable protection structure for the first operating condition according to the preset protection level, if the obtained stress data of the cable protection structure exceeds the preset stress data, a stress bearing capacity factor of the cable protection structure is generated based on the stress data and the preset protection level. The stress bearing capacity factor indicates the stress that each section of the cable protection structure can withstand under the current conditions, and the stress data reflects the statistical value of the actual stress of the cable protection structure within the target monitoring time.

[0034] It is understood that the preset protection level is used to indicate the current protection configuration level of the cable protection structure. This protection level can be determined based on preset operating conditions (such as conventional laying environment and design load range), corresponding to a specific combination of structural parameters. For example, the preset protection level can be set to reinforced protection, and its corresponding structural parameters may include: the armor layer is made of 304 stainless steel with a thickness of 8mm, or the buffer pad layer is made of high-density rubber with a thickness of 10mm, etc. The first operating condition refers to the current operating condition of the cable (such as soil compression conditions in directly buried sections of urban main roads, vibration conditions in heavy-load industrial areas, etc.). Optimizing the protection structure can be the process by which the protection structure bears the external stress under the first operating condition using its own protective capabilities. The cable protection structure optimization system can periodically collect stress data of the protection structure through stress sensors.

[0035] The detected stress data can be the statistical value of the actual stress on the cable protection structure within the target monitoring period. The target monitoring period can be preset according to the stability of the working conditions, such as 5 minutes, 6 minutes, etc. The stress average value within this period is collected in real time by stress sensors and used as the detected stress data. For example, if 5 sets of stress data are collected within a 10-minute monitoring period: 48MPa, 51MPa, 49MPa, 53MPa, and 50MPa, the average detected stress data after removing outliers is 50.2MPa. For example, for scenarios dominated by impact loads, the peak stress value within the period is taken as the detected stress data; for scenarios dominated by continuous loads, the average stress value within the period is taken as the detected stress data.

[0036] The preset stress data can be the upper limit of stress corresponding to the cable protection structure (such as 36MPa), or a critical value determined based on the material properties of the protection structure (such as the yield strength of the armor steel and the elastic limit of the padding rubber) and the structural design strength (such as the overall bearing capacity), and can be used to determine whether the protection structure is in an overload risk state.

[0037] For example, if the detected stress data is greater than the preset stress data, the current protective structure is determined to be in an overload risk state, triggering subsequent steps of coefficient calculation and determination of allowable change data; if the detected stress data is less than or equal to the preset stress data, the preset protection level remains unchanged.

[0038] The stress bearing capacity factor is used to indicate the stress that each length segment of a cable protection structure can withstand. In other words, it is the converted value of the external stress bearing capacity of each length segment of the protection structure under the current protection level, used to quantify the relationship between the protection level and the stress bearing capacity.

[0039] For example, the stress bearing capacity coefficient can be calculated based on the ratio of the comprehensive influence coefficient and the measured stress data. For instance, the stress bearing capacity coefficient = measured stress data ÷ comprehensive influence coefficient, where the comprehensive influence coefficient is a parameter determined in advance through experiments or simulations. For example, if the current protective layer thickness is 8mm, the corresponding comprehensive influence coefficient is 1.6. For instance, if the preset protection level corresponds to a comprehensive influence coefficient of 1.6, and the measured stress data is 50.2MPa, then the stress bearing capacity coefficient for each segment length = 50.2 ÷ 2.5 = 31.375. Additional note: Different protection levels correspond to different comprehensive influence coefficients. This benchmark value can be pre-stored in the system's database and retrieved directly by matching the current protection level.

[0040] S200 generates permissible change data based on the stress bearing capacity coefficient of the cable protection structure, preset stress data, and target data. The target data indicates that the adjustment amount of the protection level is related to the stress variation. The permissible change data indicates the corresponding stress warning value when the protection level is adjusted. The permissible change data is the critical stress that triggers the protection level adjustment and is dynamically changing.

[0041] It is understood that the target data is a pre-established dataset relating the adjustment amount of the protection level to the stress variation. For example, a dataset can be established that includes the adjustment amount of multiple protection levels and the stress variation, with a mapping relationship between the adjustment amount of the protection level and the stress variation. This mapping relationship can be obtained by fitting experimental data or historical data. For example, the protection level can be the thickness of the protective layer or the elastic modulus of the buffer layer. For instance, for every 1 mm increase in the thickness of the protective layer, the stress bearing capacity of the protective structure increases by 3.5 MPa / m for each length segment; for every 0.1 GPa increase in the elastic modulus of the buffer layer, the stress bearing capacity of the protective structure increases by 1.2 MPa / m for each length segment.

[0042] The allowable change data is the critical stress value that triggers the adjustment of the protection level. Since the allowable change data is variable, it avoids the problem of using a fixed predetermined stress to trigger the change of protection level in the traditional scheme, which leads to the protection level optimization scheme being inaccurate and reducing the reliability of cable protection.

[0043] For example, using preset stress data as the target, the stress value at which the change in protection level needs to be initiated is calculated based on the stress bearing capacity coefficient and the target data. The preset stress data (e.g., 36 MPa) is used to query a pre-established database to find the stress that each segment length can withstand, for example, 36 MPa / m. The difference between the stress that each segment length can withstand and the current stress bearing capacity coefficient is calculated: ΔP = 36 - 31.375 = 4.625 MPa / m, which is the total load-bearing capacity that needs to be increased by changing the target protection level. Then, the minimum necessary number of changes is determined based on ΔP, and this is combined with the minimum necessary number of changes, the stress change amount for each change, and the lead time coefficient (e.g., 0.6). The required buffer margin is calculated as follows: Minimum necessary number of changes = ΔP ÷ 1.75 MPa / m ≈ 2.64, rounded to 3. For every 1mm increase in protective layer thickness, the stress load of the protective structure increases by 3.5 MPa / m per length segment. If the corresponding minimum parameter change value is set to 0.5mm, then the stress variation corresponding to 0.5mm is 3.5 ÷ 2 = 1.75 MPa / m. Then, 3 × 1.75 MPa / m × 0.6 = 3.15 MPa, which is the buffer margin. Subtracting the buffer margin from the preset stress data yields the allowable change data, i.e., 36 - 3.15 = 32.85 MPa. It should be noted that due to the lag in stress transmission, the allowable change data also needs to be triggered in advance.

[0044] S300, provided that the target stress data of the cable protection structure meets the conditions for permissible data modification, changes the protection level of the cable protection structure from the preset protection level to the target protection level based on the actual stress variation trend data of the cable protection structure. The target protection level is higher than the preset protection level, which is generated based on the stress bearing capacity coefficient and preset stress data. The variation trend data indicates the change in actual stress per minute between the current real-time stress and the previous real-time stress.

[0045] It can be understood that target stress data refers to the latest actual stress value of the cable protection structure within the real-time monitoring period after the allowable change data is determined. The difference between target stress data and the detection stress data mentioned above is that the detection stress data is historical monitoring data (such as target monitoring period) used to calculate the stress that each section length can withstand, while target stress data is real-time trigger data used to determine whether to initiate a change in protection level.

[0046] The target stress data for the cable protection structure can meet the condition of being subject to allowable changes if the target stress data is equal to or greater than the allowable change data. If the target stress data is less than the allowable change data, it indicates that the current stress state still has a safety margin and no changes are needed; continued monitoring is sufficient. By dynamically setting the allowable change data, the change process is initiated before the stress approaches the preset stress data, avoiding the problem in traditional solutions where changes are only made when the stress reaches a fixed predetermined stress, leading to untimely changes in protection level to match stress variations.

[0047] For example, trend data is used to indicate the change in actual stress per minute between the current real-time stress and the previous real-time stress, reflecting the trend of stress change. For instance, the calculation method is: (First actual stress - Second stress value) ÷ Time interval, where the first actual stress is the current stress, the second stress value is the stress value at the previous monitoring point (i.e., the previous real-time stress), and the time interval is the duration between the two monitoring points. For example, if the first actual stress is 33.9 MPa, the second stress value at the previous monitoring point is 32.85 MPa, and the time interval is 1 minute, then the trend data = (33.9 MPa - 32.85 MPa) ÷ 1 min = 1.05 MPa / min, meaning the stress is increasing at a rate of 1.05 MPa per minute. The target protection level is the final protection level after adjustment.

[0048] The change amplitude can be calculated based on the trend data, response coefficient k (e.g., 1.5), ΔP, and the total required increase in load capacity (e.g., 3 × 1.75). Based on this change amplitude, the protection level of the cable protection structure is changed from the preset protection level to the target protection level. For example, the change amplitude = trend data × k × ΔP ÷ 3 × 1.75 = 1.05 × 1.5 × (4.625 ÷ 5.25) ≈ 1.38 mm. Based on this change amplitude, the protection level of the cable protection structure is changed from the preset protection level to the target protection level, for example, by increasing the original thickness by 1.38 mm. Then, steps S100, S200, and S300 can be continued until the obtained target stress data of the cable protection structure does not trigger the critical stress value that allows the protection level adjustment indicated by the change data, at which point the process stops.

[0049] This setup reflects the current load condition through the current detected stress data. Under heavy loads, the dynamic calculation of the current stress bearing capacity coefficient allows for data changes, enabling different stress warning values ​​in different operating scenarios (such as different load types). This allows the cable protection system to set appropriate stress warning values ​​for different scenarios, rather than using fixed, predetermined stress values ​​for protection level adjustments as in related technologies. Furthermore, adjusting the protection level based on actual stress variation trends allows for precise changes, reducing optimization delays and ensuring accurate protection level optimization, thus improving the reliability of cable protection.

[0050] In one possible implementation, before generating permissible change data based on the stress bearing capacity coefficient, preset stress data, and target data of the cable protection structure in step S200, the cable protection structure optimization method further includes: S201, Obtain the preset stress information of the cable protection structure. The preset stress information reflects the absolute upper limit stress of the cable protection structure.

[0051] It is understandable that the preset stress information of the cable protection structure can be obtained by consulting industry safety standards.

[0052] S202. Based on the preset stress information and preset margin, the preset stress data is obtained. The preset margin is a safety buffer ratio or value set in advance based on the stress tolerance capacity of the cable protection structure. The preset margin is used to reserve stress redundancy space for uncertainties in actual working conditions.

[0053] It is understandable that the stress suitable for the current working conditions is calculated based on the preset stress information and preset margin of the protective structure itself. For example, if the key threshold for extracting preset stress information is 45MPa and the preset safety margin is 20%, then the preset stress data = 45MPa × (1-20%) = 36MPa.

[0054] This setting ensures that the preset stress data is always within the safe tolerance range of the protective structure.

[0055] In one possible implementation, S200 generates permissible change data based on the stress bearing capacity coefficient of the cable protection structure, preset stress data, and target data, including: S210, obtain the stress that each segment length can withstand corresponding to the preset stress data.

[0056] It is understandable that a pre-established database can be queried based on preset stress data (such as 36MPa) to find the stress that each segment length can withstand, for example, 36MPa / m.

[0057] S220: Based on the stress that each segment length can withstand according to the preset stress data and the stress bearing capacity coefficient of the cable protection structure, the difference data is obtained.

[0058] It is understandable that the difference data is used to reflect the difference between the stress that each segment length can withstand corresponding to the preset stress data and the stress that each segment length of the cable protection structure can withstand under the current conditions.

[0059] For example, the difference between the stress that each segment length can withstand and the current stress bearing capacity is calculated based on the preset stress data. ΔP = 36 - 31.375 = 4.625 MPa / m, which is the total bearing capacity that needs to be increased by changing the target protection level.

[0060] S230 generates permissible change data based on the difference data and the target data.

[0061] It is understandable that the minimum necessary number of changes is determined based on the difference data. Then, combining the minimum necessary number of changes, the stress variation for each change, and the lead time coefficient (e.g., 0.6), the required buffer margin is calculated. For example, the minimum necessary number of changes = ΔP ÷ 1.75 MPa / m ≈ 2.64, rounded to 3 times. For every 1 mm increase in the protective layer thickness, the stress load of the protective structure increases by 3.5 MPa / m for each length segment. If the corresponding minimum parameter change value is set to 0.5 mm, then the stress variation corresponding to 0.5 mm is 3.5 ÷ 2 = 1.75 MPa / m. Then, using 3 × 1.75 MPa / m × 0.6 = 3.15 MPa, we obtain the allowable change data, i.e., 36 - 3.15 = 32.85 MPa.

[0062] This configuration allows for dynamic calculation of the current stress bearing capacity coefficient, enabling changes in the data. This allows for different stress warning values ​​in different operating conditions (such as different load types). As a result, the cable protection system can set appropriate stress warning values ​​for different scenarios to adjust the protection level, rather than using fixed predetermined stresses in related technologies to determine the protection level. This helps avoid problems such as slow optimization of protection level adjustments or inaccurate protection level optimization, thus improving the reliability of cable protection.

[0063] In one possible implementation, S230, based on the difference data and the target data, generates permissible change data, including: S231, Determine the minimum parameter change value. The minimum parameter change value indicates the minimum change value required for the thickness of the protective structure.

[0064] For example, historical data can be queried to obtain the minimum change value for the thickness of the protective structure. For instance, the minimum parameter change value could be 0.5 mm.

[0065] S232, based on the difference data and the minimum parameter change value, obtain the minimum number of necessary changes.

[0066] For example, for every 1mm increase in the thickness of the protective layer, the stress bearing capacity of the protective structure increases by 3.5MPa / m for each length segment. If the corresponding minimum parameter change value is set to 0.5mm, then the stress change corresponding to 0.5mm is 3.5÷2=1.75MPa / m. In this case, the minimum necessary number of changes = difference data ÷ 1.75MPa / m = (36-31.375)÷1.75MPa / m≈2.64, rounded down to 3 times.

[0067] S233, based on the minimum necessary number of changes, the minimum parameter change value, and the lead time coefficient, the permissible change data is obtained. The lead time coefficient indicates the advance trigger margin that needs to be reserved in the difference data.

[0068] It is understandable that the lead time factor can be between 0.5 and 0.8, and we take 0.6. The allowable change data can be calculated using the formula: Allowable Change Data = Preset Stress Data - Minimum Necessary Change Count × Minimum Parameter Change Value × Lead Time Factor. For example, Allowable Change Data = 36 - 3 × 1.75 × 0.6 = 32.85 MPa.

[0069] This configuration allows for dynamic calculation of the current stress bearing capacity coefficient, enabling changes in the data. This allows for different stress warning values ​​in different operating conditions (such as different load types), thus allowing the cable protection system to set appropriate protection levels and adjusted stress warning values ​​for different scenarios.

[0070] In one possible implementation, S300, if the target stress data of the cable protection structure meets the conditions for allowing data change, based on the actual stress variation trend data of the cable protection structure, changes the protection level of the cable protection structure from the preset protection level to the target protection level, including: S310: If the target stress data of the cable protection structure meets the conditions for allowing changes, generate protection level change data based on the actual stress variation trend data of the cable protection structure.

[0071] It is understandable that the protection level change data can be calculated based on the trend data, response coefficient k (e.g., 1.5), ΔP, and the total load capacity to be increased (e.g., 3 × 1.75). For example, the protection level change data = trend data × k × ΔP ÷ 3 × 1.75 = 1.05 × 1.5 × (4.625 ÷ 5.25) ≈ 1.38 mm.

[0072] In one possible implementation, S310, if the target stress data of the cable protection structure meets the conditions for allowing changes, protection level change data is generated based on the actual stress variation trend data of the cable protection structure, including: S311, if the target stress data of the cable protection structure meets the conditions for allowing changes, generate protection level change data based on the actual stress variation trend data and response coefficient of the cable protection structure.

[0073] It is understandable that, if the target stress data of the cable protection structure meets the conditions for allowable changes, the total load capacity to be increased can be calculated first, such as 3 × 1.75. Then, based on the trend data, response coefficient k (such as 1.5), ΔP, and the total load capacity to be increased, the protection level change data can be calculated. For example, the protection level change data = trend data × k × ΔP ÷ 3 × 1.75 = 1.05 × 1.5 × (4.625 ÷ 5.25) ≈ 1.38 mm.

[0074] In one possible implementation, S311, if the target stress data of the cable protection structure meets the conditions for allowing data changes, protection level change data is generated based on the actual stress variation trend data and response coefficient of the cable protection structure, including: S3111, based on the difference data and the total capacity to be increased, generates the first change data.

[0075] It can be understood that the total load capacity to be increased is the product of the minimum number of necessary changes and the minimum parameter change value. The first change data is used to indicate how the static stress gap will be allocated to the base adjustment amount in each step. The stress gap can be differential data.

[0076] For example, the difference data can be divided by the total load capacity to be increased to obtain the first revised data. ΔP1 = x ÷ (n × 1.75), where n is 3, and n × 1.75 = the total load capacity to be increased. The first revised data ΔP1 = 4.625 ÷ (3 × 1.75) ≈ 0.881 mm.

[0077] S3112, based on the actual stress variation trend data and response coefficient of the cable protection structure, generates second modification data.

[0078] It is understandable that the second change data is a dynamic supplement, used to supplement the amount that the basic adjustment cannot keep up with the stress change.

[0079] A second set of change data can be generated by multiplying the trend data and the response coefficient. For example, trend data × k = 1.05 × 1.5 = 1.575 mm.

[0080] S3113, based on the first change data and the second change data, generates protection level change data.

[0081] It is understandable that the first and second change data are multiplied together to obtain the protection level change data, for example, 0.881×1.575≈1.38mm.

[0082] S320, based on protection level change data, changes the protection level of the cable protection structure from the preset protection level to the target protection level.

[0083] It is understandable that the protection level of the cable protection structure is changed from the preset protection level to the target protection level according to the change amplitude. For example, the thickness is increased by 1.38mm on the basis of the original thickness. Then, steps S100, S200 and S300 are repeated until the target stress data of the obtained cable protection structure does not trigger the critical stress value that allows the change data to indicate the adjustment of the protection level.

[0084] This setup reflects the current load condition through the current detected stress data. Under heavy loads, the dynamic calculation of the current stress bearing capacity coefficient allows for data changes, enabling different stress warning values ​​in different operating scenarios (such as different load types). This allows the cable protection system to set appropriate stress warning values ​​for different scenarios, rather than using fixed, predetermined stress values ​​for protection level adjustments as in related technologies. Furthermore, adjusting the protection level based on actual stress variation trends allows for precise changes, reducing optimization delays and ensuring accurate protection level optimization, thus improving the reliability of cable protection.

[0085] In one possible implementation, the default protection level is changed by altering the thickness of the protective layer.

[0086] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0087] Corresponding to the cable protection structure optimization method described in the above embodiments, this application also provides a cable protection structure optimization system, wherein each unit of the system can implement each step of the cable protection structure optimization method. Figure 4 A structural block diagram of the cable protection structure optimization system provided in the embodiments of this application is shown. For ease of explanation, only the parts related to the embodiments of this application are shown.

[0088] Reference Figure 4 The cable protection structure optimization system includes: The generation unit is used to optimize the cable protection structure for the first working condition according to a preset protection level. When the obtained stress data of the cable protection structure exceeds the preset stress data, it generates the stress bearing capacity coefficient of the cable protection structure based on the stress data and the preset protection level. The stress bearing capacity coefficient indicates the stress that each section of the cable protection structure can withstand under the current conditions, and the stress data reflects the statistical value of the actual stress of the cable protection structure within the target monitoring time.

[0089] The calculation unit generates permissible change data based on the stress bearing capacity coefficient of the cable protection structure, preset stress data, and target data. The target data indicates that the adjustment amount of the protection level is related to the stress variation. The permissible change data indicates the corresponding stress warning value when the protection level is adjusted. The permissible change data is the critical stress that triggers the protection level adjustment and is dynamically changing.

[0090] The output unit, when the target stress data of the cable protection structure meets the conditions for allowable change, changes the protection level of the cable protection structure from a preset protection level to a target protection level based on the actual stress variation trend data of the cable protection structure. The target protection level is higher than the preset protection level, which is generated based on the stress bearing capacity coefficient and preset stress data. The variation trend data indicates the change in actual stress per minute between the current real-time stress and the previous real-time stress.
