[0038] Embodiment 1

[0039] See also Figure 1 , shows a flow chart of a cable risk detection method provided by the first embodiment of the present invention, the method can be executed by a cable risk detection device, the cable risk detection device can be implemented in the form of hardware and / or software, and the cable risk detection device can be configured in an electronic device. Figure 1 As shown, the method includes:

[0040] Step 101: Receive a production order from a user.

[0041] In this embodiment, a user's production order for cables may be received in a system such as ERP (Enterprise Resource Planning), wherein the production order records the area and design requirements for laying the cables in an overhead mode.

[0042] Step 102: When the production of the cable is completed according to the production order, a wire segment to be tested is determined in the cable.

[0043] When the production workshop completes the production of cables according to the production order, the wire segments to be tested can be screened from the produced cables.

[0044] In a specific implementation, the distance between utility poles erected in an area is queried in a production order, wherein the utility poles are used to lay cables in an overhead mode.

[0045] An appropriate test length is determined according to the spacing, wherein the test length is positively correlated to the spacing.

[0046] According to the predefined selection strategy, the wire segments that meet the test length are screened out in the cable and wait for testing.

[0047] For example, the predefined selection strategy is to select 10% of the total number of cables produced as test cables. If the test length is 36 meters and the total number of cables produced is 100, 10 cables are selected for the 36-meter pressure test. If the test length is 36 meters, 37 meters, and 40 meters, and the total number of cables produced is 100, 3 cables are selected for the 36-meter, 37-meter, and 40-meter pressure tests respectively. 10% is divided equally. If it is not divisible, it is rounded up.

[0048] Step 103: Count the threat coefficient of bird attacks when laying cables in an overhead mode in the area.

[0049] In actual applications, many birds will stay on overhead cables, causing the overhead cables to be pecked at their outer surfaces by birds with their beaks, resulting in damage to the outer surfaces of the overhead cables, thereby creating weak points, making the overhead cables more susceptible to short circuits in high temperature and high humidity environments, thereby causing fires.

[0050] In one embodiment of the present invention, step 103 may include the following steps:

[0051] Step 1031: Query the number of various types of birds recorded in various areas during multiple historical time periods.

[0052] In this embodiment, the average number of various types of birds recorded in various areas during multiple historical time periods can be queried from the bird data query platform and recorded as the time period number.

[0053] Step 1032: Calculate adjustment parameter values ​​for birds based on the number of time periods.

[0054] In this embodiment, for various birds, adjustment parameter values ​​can be calculated for various birds according to the number of corresponding time periods, and the adjustment parameter values ​​are used to adjust the harm coefficient of birds to cables.

[0055] Exemplarily, the time periods are sorted in chronological order, the difference between the number of time periods in adjacent time periods is calculated to obtain the deviation value, and all the deviation values ​​are summed to obtain the total deviation amount.

[0056] The trend coefficient is calculated as the ratio between the total amount of deviations and the average value of the number of periods.

[0057] Then, in this example, the trend coefficient can be expressed as:

[0058]

[0059] Where x is the number of the region, x = 1, 2, ..., y, y is a positive integer greater than 2, indicating the number of regions, n is the type of bird, n = 1, 2, ..., m, m is a positive integer greater than 2, indicating the number of bird types, b xn is the trend coefficient, a xin is the number of time periods in time period i, a x(i-1)n is the number of time periods in time period (i-1), i=1,2,…,j, j is a positive integer greater than 2, indicating the number of time periods.

[0060] Load a table from the local database; the table records the mapping relationship between the trend range and the parameter value.

[0061] The adjustment parameter values ​​mapped to the trend range of the trend coefficient are extracted from the table as the adjustment parameter values ​​for birds.

[0062] Step 1033: When laying cables in an overhead mode in a region and birds stay on the cables, calculate the hazard coefficient of the birds to the cables.

[0063] In this embodiment, based on the experience of understanding the attributes, living habits and other factors of various birds, the hazard coefficient of the birds to the cables can be calculated when the cables are laid in an overhead mode in the area and the birds stay on the cables.

[0064] For example, the local database is queried for the appropriate number, beak length and wingspan length of various types of birds, and the distance between cables when laying cables in an overhead mode.

[0065] On the one hand, the difference between the average value of the time period quantity and the appropriate quantity is calculated as the proliferation quantity; the first original coefficient is calculated with the natural number as the base and the ratio between the proliferation quantity and the appropriate quantity as the coefficient.

[0066] On the other hand, the second original coefficient is calculated with a natural number as the base and the ratio between the beak length and the average beak length as the coefficient.

[0067] On the other hand, the difference between the wingspan length and the distance is calculated as the contact value; and the third original coefficient is calculated using a natural number as the base and the ratio between the contact value and the distance as the coefficient.

[0068] The first original coefficient, the second original coefficient and the third original coefficient are added together to obtain the coefficient of damage caused by birds to the cables when the cables are laid in an overhead mode in the area and birds stay on the cables.

[0069] Then, in this example, the hazard factor can be expressed as:

[0070]

[0071] Where x is the number of the region, x = 1, 2, ..., y, y is a positive integer greater than 2, indicating the number of regions, n is the type of bird, n = 1, 2, ..., m, m is a positive integer greater than 2, indicating the number of bird types, i = 1, 2, ..., j, j is a positive integer greater than 2, indicating the number of time periods, δ xn is the hazard coefficient, a xin is the number of time periods in time period i, c xn is an appropriate number, d xn is the beak length, f xn is the wingspan length, g x The distance between cables.

[0072] Step 1034: For each area and each type of bird, sum the product of the adjustment parameter value and the hazard coefficient to obtain the threat coefficient.

[0073] In this embodiment, for each area and each type of bird, the product between the adjustment parameter value corresponding to each type of bird and the hazard coefficient is calculated, and all products are summed to obtain the threat coefficient.

[0074] Then, the threat coefficient can be expressed as:

[0075]

[0076] Where x is the number of the region, x = 1, 2, ..., y, y is a positive integer greater than 2, indicating the number of regions, n is the type of bird, n = 1, 2, ..., m, m is a positive integer greater than 2, indicating the number of bird types, ε is the threat coefficient, βxn is the tuning parameter, δ xn is the hazard coefficient.

[0077] Step 104: When simulating a bird attack on the outer surface of the power line segment to create a scratch point according to the number and initial depth mapped by the threat coefficient, perform an operation stress test on the power line segment according to the environment of the area to obtain the operation status of the power line segment, the end depth and temperature value of the scratch point.

[0078] In this embodiment, a production task can be generated according to the threat coefficient, and the threat coefficient is mapped into a quantity and an initial depth, wherein the quantity and the initial depth are both positively correlated with the threat coefficient. The production task instructs the engineer to simulate bird attacks on the outer surface of the wire segment to create scratch points according to the quantity and initial depth mapped by the threat coefficient. That is, scratch points are created on the outer surface of the wire segment using a tool, so that the number of scratch points created is the number mapped according to the threat coefficient, and the depth of the scratch points is the initial depth mapped by the threat coefficient, thereby simulating the damage caused by birds to the cable and facilitating subsequent experimental operations.

[0079] When the production task is completed, a test task is generated to instruct to perform an operation stress test on the wire segment according to the regional environment to achieve a highly simulated operation stress test. During the operation stress test, the operating status of the wire segment and the termination depth and temperature value of the scratch point can be detected.

[0080] In the specific implementation, the historical rainfall and temperature range per unit time recorded for each region can be queried from the weather platform.

[0081] The rainfall in the same area is compared, and the rainfall with the largest value is mapped to the watering volume per unit length when performing an operational stress test on the power line segment.

[0082] Map the upper value of the temperature interval to the ambient temperature when the line segment is stressed.

[0083] At this time, engineers can build a simulation environment based on the watering amount and ambient temperature, that is, the temperature value of the simulation environment is the ambient temperature, and water is sprinkled according to the watering amount. When the power line segment is in the simulation environment containing the watering amount and ambient temperature, the duration of the stress test is queried from the local database. During this duration, the power line segment is energized at the rated voltage to perform the operation stress test.

[0084] During the execution of the running pressure test, the temperature sensor is called to record the running status of the wire segment and measure the temperature value of the scratch point. At the end of the running pressure test, the termination depth of the scratch point is measured.

[0085] Step 105: Filter the faulty wire segment as the target segment according to the operating status, termination depth and temperature value.

[0086] In this embodiment, whether a power line segment is faulty can be evaluated comprehensively based on the operating status, termination depth and temperature value, and the faulty power line segment can be selected and recorded as the target segment.

[0087] In a specific implementation, the operating status of each power line segment may be traversed.

[0088] If the operating state is a short circuit fire state, the electric line segment is determined to be faulty and is taken as the target segment.

[0089] If the operating state is a non-short circuit fire state, the damage coefficient of the wire segment is calculated according to the termination depth and temperature value. The damage coefficient represents the damage caused by the simulation environment to the scratch point of the point line segment.

[0090] For example, the appropriate temperature of the cable is queried, and the initial depth, the end depth, the appropriate temperature and the temperature value are substituted into the following formula to calculate the damage coefficient of the wire segment:

[0091]

[0092] in, is the damage coefficient, h is the temperature value, H is the suitable temperature, l is the termination depth, L is the initial depth, t is the cable number, r is the number of the wire segment at the cable position, r = 1, 2, ..., s, s is a positive integer greater than 2, indicating the number of wire segments in the cable, p is the number of the scratch point, p∈q, p = 1, 2, ..., q, q is a positive integer greater than 2, indicating the number of scratch points, u is the number of the time point for collecting temperature values, u∈w, u = 1, 2, ..., w, w is a positive integer greater than 2, indicating the number of time points for collecting temperature values.

[0093] The damage factor is compared with a preset damage threshold.

[0094] If the damage coefficient is greater than a preset damage threshold, the power line segment is determined to be faulty and is taken as the target segment.

[0095] Step 106: Determine whether the cable meets the preset shipping standard based on the target segment.

[0096] In this embodiment, the condition of the target segment may be evaluated to determine whether the cable meets the preset shipping standard.

[0097] In a specific implementation, on the one hand, the ratio between the total number of target segments and the total number of wire segments is counted to obtain a first proportion. On the other hand, the ratio between the total number of cables with target segments and the total number of cables is counted to obtain a second proportion.

[0098] The first proportion is compared with a preset first proportion threshold, and the second proportion is compared with a preset second proportion threshold.

[0099] If the first proportion is greater than a preset first proportion threshold, and / or the second proportion is greater than a preset second proportion threshold, it is determined that the cable does not meet the preset shipping standard;

[0100] If the first proportion is less than or equal to a preset first proportion threshold, and the second proportion is less than or equal to a preset second proportion threshold, it is determined that the cable meets the preset shipping standard.

[0101] Step 107: If the cable meets the shipping standards, the cable is allowed to be provided to the user.

[0102] If the cable's pressure test results meet the shipping standards, the cable is allowed to be provided to the user, that is, supplied to the user.

[0103] Step 108: If the cable does not meet the shipping standard, the cable is scrapped when it does not meet the design requirements, and is provided to the user when it meets the design requirements.

[0104] If the cable's pressure test results do not meet the shipping standards, it is determined whether the cable meets the design requirements, that is, whether the cable meets the user's order requirements.

[0105] When the cable does not meet the design requirements, the cable is scrapped, and when the cable meets the design requirements, the cable is provided to the user.

[0106] In this embodiment, a production order from a user is received; the area and design requirements for laying cables in an overhead mode are recorded in the production order; when the cable production is completed according to the production order, the wire segment to be tested is determined in the cable; the threat coefficient of bird attack when laying the cable in an overhead mode in the area is counted; when the outer surface of the wire segment is simulated to attack the bird to create a scratch point according to the number and initial depth mapped by the threat coefficient, an operation stress test is performed on the wire segment to obtain the operation status of the wire segment, the termination depth and temperature value of the scratch point; the faulty wire segment is selected as the target segment based on the operation status, termination depth and temperature value; based on the target segment, it is determined whether the cable meets the preset shipping standard; if it meets the shipping standard, the cable is allowed to be provided to the user; if it does not meet the shipping standard, the cable is scrapped if it does not meet the design requirements, and is provided to the user if it meets the design requirements. This embodiment focuses on the threat posed by bird activities to cables. It performs a highly simulated operation stress test on the cables according to the environment of the area where the cables are laid, thereby realizing personalized testing, effectively improving the accuracy of detecting cable defects, ensuring the performance consistency of the cables, allowing them to be used normally in the laying area, reducing the problem of cable short circuits and fires, and ensuring the normal operation of the power system.
