[0028] Embodiment 1

[0029] Figure 1 Schematic diagram of the structure of the insulation layer aging assessment device based on the area of ​​interest of the cable laying environment provided in the first embodiment of the present application. Figure 1 As shown, the device comprises:

[0030] The cable parameter acquisition module 110 is used to acquire the anti-aging parameters of the cable; wherein the anti-aging parameters include material composition parameters and content parameters of the material composition parameters;

[0031] A focus region feature acquisition module 120 is used to obtain a target feature extraction result of the cable in the focus region;

[0032] An aging analysis module 130 is used to input the anti-aging parameter and the target feature extraction result into a pre-built aging analysis model, and determine the relative aging coefficient of the area of ​​interest according to the output result of the aging analysis model; wherein the relative aging coefficient is the ratio of the aging speed of the area of ​​interest to the aging speed of a normal area;

[0033] The alarm module 140 is configured to determine the aging degree of the concerned area according to the relative aging coefficient, and generate aging alarm information when the aging degree reaches a preset aging degree threshold.

[0034] This application is applicable to the scenario of detecting the aging degree of the cable area of ​​concern. Specifically, the acquisition of target feature extraction results, the determination of the relative aging coefficient of the area of ​​concern, and the generation of aging alarm information can be performed by the intelligent terminal device, and the staff can take corresponding maintenance measures for the cable according to the determined aging degree to ensure the normal operation of the cable.

[0035] Based on the above usage scenarios, it can be understood that the executor of the present application can be a smart terminal device, such as a desktop computer, a laptop computer, a mobile phone, a tablet computer, and interactive multimedia, etc., and no excessive limitations are made here.

[0036] The cable parameter acquisition module 110 is used to obtain the anti-aging parameters of the cable.

[0037] Cable is a device that can be used for communication or power transmission. The cable insulation layer is a material layer that effectively prevents the flow of current between conductors and prevents problems such as short circuit and leakage. The aging resistance parameter can be a physical property parameter associated with the aging resistance of the cable insulation layer, which can include material composition parameters and content parameters of material composition parameters.

[0038] Specifically, the material composition parameter may refer to the specific chemical composition included in the material used for the cable insulation layer. The material composition parameter of the cable insulation layer may include polyethylene resin, phenolic or amine antioxidants, carbon black, and the like.

[0039] The material composition parameters and the content parameters of the material composition parameters are generally recorded in the cable production report, specification description and other cable-related descriptive documents. The material composition parameters and the content parameters of the material composition parameters can be obtained by reading the descriptive documents.

[0040] The focus region feature acquisition module 120 is used to obtain the target feature extraction result of the cable in the focus region.

[0041] The focus area may refer to a cable area that ages faster and needs special attention, and may include a turning area, a hanging area, a heat accumulation area, etc. The target feature extraction result may refer to features related to the focus area presented by the cable in the focus area.

[0042] Depending on the area of ​​interest, the target feature extraction result of the cable in the area of ​​interest is also different. Specifically, for example, the target feature extraction result of the cable in the turning area is the turning radius; the target feature extraction result of the cable in the suspended area is the suspended length; the target feature extraction result of the cable in the heat accumulation area is the heat accumulation temperature.

[0043] The target feature extraction results of the cable in the area of ​​interest can be obtained by field measurement and input by the staff. Optionally, the method of obtaining the turning radius or the overhang length can also be adopted by collecting the image information of the cable from at least one angle through a camera, and using image recognition technology to identify and analyze the image information, so as to obtain the turning radius or the overhang length. Among them, image recognition technology can be a computer vision technology, which is designed to enable the computer to understand and interpret the image content, and can automatically analyze and identify objects, scenes, patterns or features in the image. Optionally, the method of obtaining the accumulated heat temperature can also be obtained by using a temperature sensor installed in the heat accumulation area. Among them, the temperature sensor is a device that can detect and measure the ambient temperature.

[0044] The aging analysis module 130 is used to input the anti-aging parameter and the target feature extraction result into a pre-built aging analysis model, and determine the relative aging coefficient of the area of ​​interest according to the output result of the aging analysis model.

[0045] The relative aging coefficient may refer to the ratio of the aging rate of the concerned area to the aging rate of the normal area. The normal area may refer to the cable area that is not affected by external aging factors and undergoes natural aging; the aging rate may refer to the change in the aging degree of the cable insulation layer per unit time; the aging degree may refer to the degradation degree of the performance of the cable insulation layer. In this solution, the aging degree particularly refers to the degradation degree of the mechanical strength and toughness of the cable insulation layer.

[0046] The aging analysis model can be a neural network model for determining the relative aging coefficient of the area of ​​interest of the cable. The neural network model can be a computational model based on the structure and function of biological neurons, which realizes data processing and analysis through the connection and information transmission between multiple nodes. The aging analysis model can be pre-built by inputting the aging resistance parameters and target feature extraction results of a large number of different cables as training samples into the neural network basic model to train it and obtain the aging analysis model.

[0047] The output result of the aging analysis model is the relative aging coefficient of the area of ​​interest determined and fed back by the aging analysis model based on the input aging resistance parameters and the target feature extraction results. Specifically, the way in which the aging analysis model determines the relative aging coefficient of the area of ​​interest varies according to the area of ​​interest: if the area of ​​interest is a turning area, the elastic parameters of the cable are determined according to the aging resistance parameters, the deformation degree parameters of the turning area of ​​the cable are determined, and the relative aging coefficient of the turning area is determined according to the elastic parameters and the deformation degree parameters; if the area of ​​interest is a suspended area, the elastic parameters of the cable are determined according to the aging resistance parameters, the average stress data of the suspended area is determined according to the elastic parameters and the suspended length, and the relative aging coefficient of the suspended area is determined according to the average stress data; if the area of ​​interest is a heat accumulation area, the heat resistance parameters of the cable are determined according to the aging resistance parameters, and the relative aging coefficient of the heat accumulation area is determined according to the heat resistance parameters and the accumulated heat temperature.

[0048] The alarm module 140 is configured to determine the aging degree of the concerned area according to the relative aging coefficient, and generate aging alarm information when the aging degree reaches a preset aging degree threshold.

[0049] The method of determining the aging degree of the area of ​​concern based on the relative aging coefficient can be adopted by obtaining the aging rate of the material composition parameters, and determining the aging rate of the normal area of ​​the cable based on the aging rate of each material composition parameter and the content parameter, obtaining the usage time of the cable and determining the aging degree of the area of ​​concern based on the usage time, the aging rate of the normal area and the relative aging coefficient.

[0050] The preset aging degree threshold may be the upper limit of the aging degree indicating that the cable can continue to operate normally and does not require maintenance by staff. The aging alarm information may be used to remind staff that the aging degree of the cable's area of ​​concern has exceeded the preset aging degree threshold, and that the area of ​​concern may have plastic deformation, fracture failure, and fatigue failure, which require timely processing by staff. The details of the aging alarm information may include the aging degree and location information of the area of ​​concern. The aging alarm information may be generated by comparing the aging degree of the area of ​​concern with the preset aging degree threshold. If the aging degree of the area of ​​concern is greater than or equal to the preset aging degree threshold, the display device of the terminal device is controlled to pop up an alarm window, and the details of the aging alarm information are displayed in the alarm window.

[0051] In this technical solution, optionally, the alarm module is specifically used to:

[0052] Obtaining the aging speed of the material component parameters, and determining the aging speed of a normal area of ​​the cable according to the aging speed of each material component parameter and the content parameter;

[0053] Acquire the usage time of the cable, and determine the aging degree of the concerned area according to the usage time, the aging speed of the normal area, and the relative aging coefficient;

[0054] When the aging degree reaches a preset aging degree threshold, aging alarm information is generated.

[0055] The aging rate of the material composition parameter can be obtained by conducting a thermal aging experiment on all materials composed of the material composition parameter, or by using the material composition parameter as a query condition to query the material performance manual and engineering material database and other literature related to material performance, and determine it based on the service life recorded in the literature. The aging rate of the normal area of ​​the cable can be determined by multiplying the aging rate of each material composition parameter with the content parameter, and adding the multiplication results of each material composition parameter to obtain the aging rate of the normal area of ​​the cable.

[0056] The service life of a cable may refer to the length of time between the current time point and the time point when the cable starts to operate, which can be obtained by querying the laying and maintenance records of the cable, or by querying the cable management system that records the operating status of each cable. The aging degree of the concerned area can be determined by multiplying the service life with the aging rate of the normal area to obtain the aging degree of the normal area, and multiplying the aging degree of the normal area with the relative aging coefficient to obtain the aging degree of the concerned area.

[0057] Here is a sample code to determine the aging of a region of interest:

[0064] bend_aging_degree=straight_aging_degree*bend_aging_factor

[0065] return straight_aging_degree,bend_aging_degree

[0066] Example usage:

[0079] print(f"Aging degree of normal cable area: {straight_aging_degree:.2f}")

[0080] print(f"Aging degree of cable bending area: {bend_aging_degree:.2f}")

[0081] The advantage of this arrangement of the present scheme is that by determining the aging degree of the normal area of ​​the cable based on the aging speed and content parameters of each material component parameter, the length of use and the relative aging coefficient, tedious manual data detection can be avoided and the efficiency of determining the aging degree of the normal area of ​​various cables can be improved.

[0082] In the example of the present application, the cable parameter acquisition module is used to obtain the anti-aging parameters of the cable; wherein the anti-aging parameters include material composition parameters and content parameters of the material composition parameters; the focus area feature acquisition module is used to obtain the target feature extraction results of the cable in the focus area; the aging analysis module is used to input the anti-aging parameters and the target feature extraction results into a pre-built aging analysis model, and determine the relative aging coefficient of the focus area according to the output results of the aging analysis model; wherein the relative aging coefficient is the ratio of the aging speed of the focus area to the aging speed of the normal area; the alarm module is used to determine the aging degree of the focus area according to the relative aging coefficient, and generate aging alarm information when the aging degree reaches a preset aging degree threshold. This technical solution can determine the aging of the focus area relative to the normal area by obtaining the anti-aging parameters of the cable and the target feature extraction results in the focus area, thereby improving the efficiency and accuracy of determining the aging speed of each area of ​​the cable.

[0083] Embodiment 2

[0084] Figure 2 It is a structural schematic diagram of the insulation layer aging evaluation device based on the area of ​​interest of the cable laying environment provided in the second embodiment of the present application. This solution has made better improvements on the basis of the above embodiments, and the specific improvements are as follows: the area of ​​interest includes a turning area, and the target feature extraction result includes the turning radius of the cable in the turning area; accordingly, the aging analysis module includes: an elastic parameter acquisition unit, which is used to determine the elastic parameters of the cable according to the aging resistance parameters; a deformation degree determination unit, which is used to determine the deformation degree parameters of the turning area of ​​the cable; a relative coefficient determination unit, which is used to determine the relative aging coefficient of the turning area according to the elastic parameters and the deformation degree parameters.

[0085] like Figure 2 As shown, the device comprises:

[0086] The cable parameter acquisition module 210 is used to acquire the anti-aging parameters of the cable; wherein the anti-aging parameters include material composition parameters and content parameters of the material composition parameters;

[0087] A focus region feature acquisition module 220 is used to obtain target feature extraction results of the cable in the focus region;

[0088] An aging analysis module 230 is used to input the anti-aging parameter and the target feature extraction result into a pre-built aging analysis model, and determine the relative aging coefficient of the area of ​​interest according to the output result of the aging analysis model; wherein the relative aging coefficient is the ratio of the aging speed of the area of ​​interest to the aging speed of a normal area;

[0089] The alarm module 240 is used to determine the aging degree of the concerned area according to the relative aging coefficient, and generate aging alarm information when the aging degree reaches a preset aging degree threshold.

[0090] The aging analysis module 230 includes:

[0091] An elastic parameter acquisition unit 2301, configured to determine the elastic parameters of the cable according to the aging resistance parameters;

[0092] A deformation degree determination unit 2302, used to determine a deformation degree parameter of a turning area of ​​the cable;

[0093] The relative coefficient determination unit 2303 is used to determine the relative aging coefficient of the turning area according to the elastic parameter and the deformation degree parameter.

[0094] The turning area of ​​the cable may refer to a cable area where the extension directions of the cables are not on the same straight line. The turning radius may refer to the radius of a circle with the turning area of ​​the cable as an arc.

[0095] The elastic parameter can be a parameter used to describe the elastic properties of the cable insulation layer, that is, the correlation between the deformation degree of the cable insulation layer and the stress data. The method of determining the elastic parameters of the cable according to the aging resistance parameters can be adopted to obtain the elastic parameters of the material composition parameters, and determine the elastic parameters of the cable according to the elastic parameters and content parameters of each material composition parameter. Among them, the elastic parameters of the material composition parameters can be parameters that describe the correlation between the deformation degree and stress data of a material completely composed of the material composition parameters. By using the material composition parameters as the query conditions, querying the material performance manual and the engineering material database and other literature related to material performance, the elastic parameters of the material composition parameters can be determined. The method of determining the elastic parameters of the cable can be adopted to multiply the elastic parameters of each material composition parameter with the content parameter, and add the multiplication results of each material composition parameter to obtain the elastic parameters of the cable.

[0096] The deformation degree parameter may be a parameter used to describe the deformation degree of the cable in the turning area before and after the turn. The method for determining the deformation degree parameter of the turning area of ​​the cable may be to obtain the radius information of the cable and the length information of the turning area, determine the inner length and the outer length of the turning area according to the radius information, the length information and the turning radius, and determine the deformation degree parameter of the turning area of ​​the cable according to the inner length, the outer length and the length information.

[0097] The relative aging coefficient of the turning area can be determined by determining the average stress data of the turning area according to the elastic parameters and the deformation degree parameters, and then determining the relative aging coefficient of the turning area according to the average stress data.

[0098] In the technical solution, optionally, the deformation degree determining unit is specifically used to:

[0099] Obtaining the radius information of the cable and the length information of the turning area;

[0100] Determine the inner length and the outer length of the turning area according to the radius information and the turning radius;

[0101] A deformation degree parameter of a turning area of ​​the cable is determined according to the inner length, the outer length and the length information.

[0102] The radius information of the cable may refer to the radius of the cross section of the cable in the direction perpendicular to the extension of the cable. The radius information of the cable is generally recorded in the production report of the cable and the specification description and other description documents related to the cable. The radius information of the cable can be obtained by reading the description documents. The radius information of the cable can also be obtained by identifying and analyzing the image information of the cable using image recognition technology.

[0103] The length information of the turning area may refer to the length of the cable center axis between the position where the cable starts to turn and the position where the cable ends to turn. The length information of the turning area may be obtained by determining the turning center of the turning area according to the turning radius of the turning area, connecting the turning center and the position where the turning starts as a first straight line, connecting the turning center and the position where the turning ends as a second straight line, determining the angle between the two straight lines, and determining the length information of the turning area according to the turning radius and the angle.

[0104] The inner length may refer to the inner edge length of the cable turning area relative to the turning circle center; the outer length may refer to the outer edge length of the cable turning area relative to the turning circle center. The inner length and the outer length of the turning area may be determined by subtracting the radius information from the turning radius to obtain the inner diameter of the turning area, adding the turning radius to the radius information to obtain the outer diameter of the turning area, determining the inner length of the turning area according to the inner diameter of the turning and the above angle, and determining the outer length of the turning area according to the outer diameter of the turning and the above angle.

[0105] The method for determining the deformation degree parameter of the turning area of ​​the cable may be to calculate the difference between the outer length and the inner length, and calculate the ratio of the difference to the length information as the deformation degree parameter of the turning area of ​​the cable.

[0106] The following is a sample code for determining the deformation degree parameter of the cable's turning area:

[0107]

[0108]

[0109]

[0110] The advantage of this arrangement of the present scheme is that by determining the inner length and outer length of the turning area according to the radius information of the cable and the turning radius, and determining the deformation degree parameter according to the inner length, outer length and length information of the turning area, the deformation characteristics of the turning area of ​​the cable can be described more accurately, providing an important basis for the subsequent determination of the relative aging coefficient of the turning area of ​​the cable.

[0111] In the technical solution, optionally, the relative coefficient determination unit is specifically used to:

[0112] Determining average stress data of the turning area according to the elastic parameter and the deformation degree parameter;

[0113] A relative aging coefficient of the turning area is determined based on the average stress data.

[0114] The average stress data may refer to the average value of the internal force acting on each position in the turning area. The average stress data of the turning area may be determined by multiplying the elastic parameter by the deformation degree parameter to obtain the average stress data of the turning area.

[0115] The relative aging coefficient of the turning area can be determined by calculating the ratio of the average stress data to the preset standard stress data as the relative aging coefficient of the turning area, wherein the preset standard stress data can be the stress data of the normal area of ​​the cable obtained in advance.

[0116] The advantage of this arrangement of the present scheme is that by determining the average stress data of the turning area based on the elastic parameters and the deformation degree parameters, and determining the relative aging coefficient of the turning area based on the average stress data, the overall aging condition of the turning area relative to the normal area can be described more comprehensively and quantitatively, thereby improving the efficiency of determining the aging degree of the turning area.

[0117] The benefit of this arrangement of the present scheme is that by determining the elastic parameters of the cable according to the aging resistance parameters, and determining the deformation degree parameters of the turning area of ​​the cable, and then determining the relative aging coefficient of the turning area according to the elastic parameters and the deformation degree parameters, it can help to accurately evaluate the aging degree of the turning area of ​​the cable.

[0123] An aging analysis module 330 is used to input the anti-aging parameter and the target feature extraction result into a pre-built aging analysis model, and determine the relative aging coefficient of the area of ​​interest according to the output result of the aging analysis model; wherein the relative aging coefficient is the ratio of the aging speed of the area of ​​interest to the aging speed of a normal area;

[0124] The alarm module 340 is used to determine the aging degree of the concerned area according to the relative aging coefficient, and generate aging alarm information when the aging degree reaches a preset aging degree threshold.

[0125] The aging analysis module 330 is specifically used for:

[0126] Determining the elastic parameters of the cable according to the aging resistance parameters;

[0127] Determining average stress data of the suspended area according to the elastic parameter and the suspended length;

[0128] A relative aging coefficient of the suspended area is determined according to the average stress data.

[0129] The hanging area of ​​the cable may refer to the area of ​​the cable without supports. The hanging length may refer to the distance between two adjacent supports of the cable.

[0130] The method of determining the elastic parameters of the cable according to the aging resistance parameters can adopt the method of obtaining the elastic parameters of the material composition parameters, and determining the elastic parameters of the cable according to the elastic parameters of the material composition parameters and the content parameters.

[0131] The average stress data may refer to the average value of the internal force acting on each position in the suspended area. The average stress data of the suspended area may be determined by obtaining the cross-sectional area information and the self-weight density information of the cable, determining the stress distribution function of each position in the suspended area according to the elastic parameters, the cross-sectional area information, the self-weight density information and the mechanical principle, integrating the stress distribution function, dividing the integral result by the suspended length, and obtaining the average stress data of the suspended area.

[0132] The relative aging coefficient of the suspended area can be determined by calculating the ratio of the average stress data to the preset standard stress data as the relative aging coefficient of the suspended area, wherein the preset standard stress data can be the stress data of the normal area of ​​the cable obtained in advance.

[0133] The benefit of this arrangement of the present scheme is that by determining the elastic parameters of the cable based on the aging resistance parameters, determining the average stress data of the suspended area based on the elastic parameters and the suspended length, and then determining the relative aging coefficient of the suspended area based on the average stress data, it can help to accurately evaluate the aging degree of the suspended area of ​​the cable.

[0134] In the technical solution, optionally, the area of ​​interest includes a heat accumulation area, and the target feature extraction result includes the heat accumulation temperature of the cable in the heat accumulation area;

[0135] Accordingly, the aging analysis module includes:

[0136] Determining the heat resistance parameters of the cable according to the aging resistance parameters;

[0137] A relative aging coefficient of the heat accumulation area is determined according to the heat resistance parameter and the heat accumulation temperature.

[0138] The heat accumulation area of ​​the cable may refer to the cable area in an environment with poor heat dissipation conditions or near a heat source. The heat accumulation temperature may refer to the temperature value of the environment where the heat accumulation area is located.

[0139] The heat resistance parameter may be a parameter used to describe the heat resistance performance of the cable insulation layer. The heat resistance parameter of the cable may be determined according to the aging resistance parameter, by obtaining the heat resistance parameter of the material composition parameter, multiplying the heat resistance parameter of each material composition parameter with the content parameter, and adding the multiplication results of each material composition parameter to obtain the heat resistance parameter of the cable. Among them, the heat resistance parameter of the material composition parameter may be a parameter describing the heat resistance performance of a material completely composed of the material composition parameter. The heat resistance parameter of the material composition parameter may be determined by using the material composition parameter as a query condition and querying the material performance manual, the engineering material database and other literature related to material performance.

[0140] The relative aging coefficient of the heat accumulation area can be determined by obtaining the ambient temperature of the normal area of ​​the cable, calculating the temperature difference between the ambient temperature and the heat accumulation temperature, dividing the heat resistance parameter by the temperature difference coefficient and multiplying the temperature difference to obtain the relative aging coefficient of the heat accumulation area. The temperature difference coefficient can be an empirical value set based on experimental data and historical data.

[0141] The benefit of this arrangement of the present invention is that by determining the heat resistance parameters of the cable according to the aging resistance parameters, and determining the relative aging coefficient of the heat accumulation area according to the heat resistance parameters and the heat accumulation temperature, it can help to accurately evaluate the aging degree of the heat accumulation area of ​​the cable.
