These drawings and textual descriptions are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0044] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0045] It should be noted that, in this article, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element. In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.

[0046] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0048] At present, when working on the conductor and ground wire, the operating safety distance is limited, making the available space for equipotential workers very narrow. Especially when working on a ladder, the weight of the human body and tools is about 100kg, which increases the load on the conductor and ground wire, and its stress also increases accordingly, and the sag increases and drops more, which reduces the distance between the working point and the live wire or crossover below, posing a major safety hazard. In order to ensure the safety of live workers and the power grid, it is necessary to perform corresponding verification of the changes in conductor and ground wire stress and sag during the on-site investigation to determine whether the ladder can be used for operation. This requires accurate calculations in advance, but the manual calculation of the changes in conductor and ground wire stress and sag is relatively complicated and time-consuming.

[0049] In response to the above-mentioned technical problems, the embodiments of the present application provide a safety assessment device, method, electronic device and storage medium for conductive wire hanging ladder operations, which can improve the accuracy and efficiency of safety assessment during conductive wire hanging ladder operations, while reducing the complexity and error rate of manual calculations, thereby ensuring the stable operation of the power system and effectively protecting the lives of operators.

[0050] The embodiment of the present application provides a safety assessment device, method, electronic device and storage medium for conducting wire hanging ladder operation.

[0051] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0052] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of the conductive wire hanging ladder operation safety assessment device provided in the embodiment of the present application. The conductive wire hanging ladder operation safety assessment device provided in this embodiment can be executed in the distribution network. The conductive wire hanging ladder operation safety assessment device can specifically include a software interface module 101, a back-end calculation module 102, a safety judgment module 103 and a display module 104, as follows:

The basic data includes but is not limited to ground wire parameters, meteorological condition data, load condition data, etc., while the judgment conditions involve operation type, environmental judgment, load judgment, etc. Figure 2 As shown, a schematic diagram of the software interface provided by the conductive wire hanging ladder operation safety assessment device in this embodiment.

[0055] The back-end calculation module 102 is used to calculate the corresponding ladder operation safety distance according to the input basic data and basic judgment conditions through the back-end calculation model;

This calculation process includes integrating complex physical and engineering formulas. The back-end calculation module can automate this calculation process to improve the accuracy and efficiency of the safe distance calculation.

[0057] The safety judgment module 103 is used to compare the safety distance of the ladder operation with a preset safety distance threshold to determine whether the safety distance of the ladder operation is qualified and obtain a safety judgment result;

[0058] Specifically, the safety judgment module 103 compares the calculated safety distance of the ladder operation with the preset safety distance threshold to determine whether the operation is safe. This step is the key in the evaluation process and is directly related to the safety of the operator.

[0059] Display module 104, used to display the safety judgment result;

[0060] Specifically, the display module 104 is used to display the safety judgment result to the user, and the result is presented in an intuitive way, such as using different colored fonts or icons to indicate whether the operation is safe. For example, if the safety distance during the ladder operation is ≥ the safety distance specified in the regulations, the output prompt is qualified, and the display is green font; if the safety distance during the ladder operation is < the safety distance specified in the regulations, the output prompt is unqualified, and the display is red font. In addition, an audible and visual alarm can be issued according to the safety judgment result. Figure 3 As shown, Figure 3 The display interface of the display module is displayed.

[0061] It can be seen that the conductive wire hanging ladder operation safety assessment device provided in this embodiment can significantly reduce the risk of safety accidents caused by misjudgment or calculation errors by accurately calculating and comparing safety distances in real time; the automated calculation process reduces the time and potential errors of manual calculations, making safety assessments faster and more reliable, thereby improving the efficiency of operation preparation; reducing the manpower and material resources required for on-site surveys and manual calculations, and reducing the overall operation cost; the consistency and reliability of the assessment results are improved through the software-solidified calculation model and preset safety thresholds; the software interface module provides an intuitive user interface, so that non-professional users can easily perform safety assessments, and the safety judgment results provided support management and operators to make more scientific operation decisions.

[0064] Specifically, the conductive wire hanging ladder operation safety assessment device in this embodiment also provides an authorization judgment module, the purpose of which is to ensure the legal use of the software. When the software is started, it is determined whether the currently started software has authorization information by checking the computer's hardware information. If the software is authorized, the user can directly enter the software interface to operate; if it is not authorized, the user needs to enter the authorization code to obtain the right to use. It helps to protect the intellectual property rights of the software, prevent unauthorized copying and use, and ensure the legitimate rights and interests of software developers and patent holders.

[0065] This embodiment can effectively prevent the illegal copying and dissemination of software and protect the intellectual property rights of software developers and patent holders through the authorization judgment module; only authorized users can use the software, which helps to maintain the legality of software use and avoid legal risks caused by illegal use; the authorization judgment module can be used as part of the software security mechanism to prevent unauthorized access and potential malicious attacks and improve the security of the software.

[0072] Ladder operation parameters: including additional loads during ladder operation, such as the weight of operators, tools and materials.

[0079] The basic judgment conditions include the following:

[0080] Conditions for judging the type of operation: Determine the type of operation, such as ladder operation or equipotential operation.

[0081] Environmental judgment conditions: Determine whether there are special environmental conditions such as icing.

[0086] Calculation parameter selection conditions: Select the correct calculation parameters for safety assessment.

[0087] Safety assessment conditions: Determine whether the operation is safe based on the safety assessment results.

[0088] By defining the basic data and basic judgment conditions in detail, this embodiment enables the evaluation device to more accurately calculate the safe distance of ladder operations and improve the accuracy of the evaluation results; it covers a wide range of data and conditions to ensure that the evaluation device can adapt to different working environments and conditions and improve the comprehensiveness of the evaluation; by considering a variety of meteorological, geographical and structural parameters, the evaluation device can adapt to changing working environments and improve its adaptability; by comprehensively considering various loads and safety specification parameters, the evaluation device can more effectively identify potential safety risks and improve operational safety; the user only needs to input basic data and meet basic judgment conditions, and the evaluation device can automatically complete complex calculations, thereby simplifying the operation process.

[0089] Furthermore, in some embodiments, the backend computing module 102 may specifically include:

[0090] A sag calculation unit is used to calculate the sag at any point under a non-uniformly distributed load based on the basic data according to a preset sag calculation formula;

[0091] The safety distance calculation unit is used to calculate the safety distance of the hanging ladder operation corresponding to the hanging ladder based on the sag and basic data according to a preset safety distance calculation formula.

[0092] Specifically, the back-end calculation module 102 specifically includes a sag calculation unit and a safety distance calculation unit. This module is the core of the safety assessment device and is responsible for performing complex calculation tasks based on the input basic data and basic judgment conditions to determine the safe distance of the ladder hanging operation. Among them, the sag calculation unit is responsible for calculating the sag of the ground wire under non-uniform load, which is a key step in evaluating the safe distance of the ladder hanging operation. The sag calculation subunit is responsible for calculating the sag at any point under non-uniform load based on the horizontal distance between any point on the conductor and the low hanging point in the basic data, the conductor use stress and the comprehensive load ratio under the target meteorological conditions, using a preset sag calculation formula.

[0093] By subdividing the calculation units, this embodiment can more accurately calculate the sag and comprehensive load ratio of the ground wire, thereby improving the accuracy of the safety assessment; the automated calculation function of the back-end calculation module reduces the need for manual calculations and improves the efficiency of the assessment process; through the preset calculation formula and the collaborative work of the sub-units, the assessment device can provide more reliable safety assessment results; accurate sag calculation results provide important decision-making support for management and operators, helping them determine the safety of their operations.

[0094] Further, in some embodiments, the sag calculation unit may specifically include:

[0095] The height difference angle calculation subunit is used to calculate the corresponding height difference angle based on the constant span in the basic data and the height difference of the adjacent tower conductor suspension points according to the preset height difference angle calculation formula;

[0096] The sag calculation subunit is used to calculate the sag at any point under non-uniformly distributed load according to the preset sag calculation formula based on the horizontal distance between any point on the conductor and the low suspension point in the basic data, the conductor application information under the target meteorological conditions and the comprehensive specific load.

[0097] Specifically, the sag calculation unit in this embodiment includes a height difference angle calculation subunit and a sag calculation subunit, wherein the height difference angle calculation subunit uses a preset height difference angle calculation formula to calculate the height difference angle according to the constant span in the basic data and the height difference of the conductor suspension points of adjacent towers. The height difference angle refers to the ratio of the vertical height difference of the conductor between two adjacent towers to the span, which is an important parameter for calculating the sag of the conductor. The sag calculation subunit uses a preset sag calculation formula to calculate the sag at any point under the non-uniformly distributed load according to the horizontal distance between any point on the conductor and the low suspension point in the basic data, the conductor use stress and the comprehensive specific load under the target meteorological conditions. The sag refers to the vertical distance between one support point and another support point of the conductor under the action of its own weight and the external load.

[0098] By accurately calculating the height difference angle and sag, the evaluation device of this embodiment can more accurately simulate the behavior of the conductor under different load conditions, thereby improving the accuracy of the safety assessment; accurate sag calculation helps to ensure that the operating personnel maintain a sufficient safe distance from the live conductors or crossing objects, thereby reducing the risk of electric shock and short circuit; fast and accurate sag calculation enables management and operating personnel to quickly make decisions on whether to perform operations, thereby improving the efficiency of operation preparation and execution; by replacing part of the on-site survey work with software evaluation tools, the workload of on-site operators is reduced, and the cost and risk of on-site surveys are reduced; automated sag calculation reduces the time of manual calculations, making the evaluation process faster and improving overall work efficiency.

[0099] Furthermore, in some embodiments, the sag calculation unit may further include:

[0100] The ice-free comprehensive specific load calculation subunit is used to calculate the comprehensive specific load under ice-free conditions based on the conductor deadweight specific load and ice-free wind pressure specific load in the basic data;

[0101] The icing comprehensive specific load calculation subunit is used to calculate the comprehensive specific load under icing conditions based on the conductor deadweight specific load, ice weight specific load and icing wind pressure specific load in the basic data.

[0102] Specifically, the sag calculation unit in this embodiment includes a calculation subunit for the comprehensive specific load under ice-free and ice-covered conditions. Among them, the ice-free comprehensive specific load calculation subunit is responsible for calculating the comprehensive specific load under ice-free conditions based on the input basic data (such as the conductor's own weight specific load and the ice-free wind pressure specific load), taking into account factors such as the wind load adjustment coefficient, wind speed unevenness coefficient, and overhead line body coefficient, so as to accurately calculate the load on the conductor under ice-free conditions. The ice-covered comprehensive specific load calculation subunit is responsible for calculating the comprehensive specific load under ice-covered conditions based on the input basic data (such as the conductor's own weight specific load, ice weight specific load, and ice-covered wind pressure specific load), taking into account factors such as ice thickness and ice-covered wind load increase coefficient, so as to accurately calculate the load on the conductor under ice-covered conditions. The calculation results of these subunits will directly affect the calculation of sag, and then affect the assessment of the safe distance of the ladder hanging operation.

[0103] In this embodiment, by calculating the comprehensive specific loads in the non-ice and ice-covered conditions respectively, the evaluation device can more accurately simulate the actual load conditions and improve the accuracy of the safety evaluation; the evaluation device can adapt to different meteorological conditions, and can provide accurate safety evaluation regardless of whether it is non-ice or ice-covered, thereby enhancing the environmental adaptability of the device; accurate comprehensive specific load calculation helps to more accurately evaluate the stress and sag of the conductor under different loads, thereby reducing operational risks and improving operational safety; through accurate evaluation, unnecessary on-site surveys and repeated operations can be avoided, human resource allocation can be optimized, and operational efficiency can be improved; accidents and maintenance requirements caused by incorrect evaluations can be reduced, thereby reducing long-term maintenance costs.

[0104] Furthermore, in some embodiments, the safety distance calculation unit is specifically used to:

[0105] According to the preset safety distance calculation formula, the corresponding ladder operation safety distance is calculated based on the constant normal operating safety distance in the basic data, the normal operating conductor sag, the ladder operation height information and the sag at any point under non-uniform load.

[0106] Specifically, the safety distance calculation unit in this embodiment is part of the back-end calculation module, which is responsible for calculating the safety distance of the ladder operation according to the preset safety distance calculation formula, combined with the basic data and the calculated sag. The safety distance calculation unit uses basic data, including the constant normal working condition safety distance, the normal working condition conductor sag, the ladder operation height information, and the sag at any point under the non-uniform load, to calculate the corresponding ladder operation safety distance. The unit is suitable for various operating conditions, including different meteorological conditions, conductor load conditions and operating environments, to ensure that accurate safety distance assessment can be provided in various situations.

[0107] This embodiment improves the accuracy of safety assessment and reduces the possibility of human calculation errors by accurately calculating the safety distance of ladder operations; accurate safety distance assessment helps to ensure that operators maintain a sufficient safety distance from live wires or crossing objects, thereby reducing the risk of electric shock and short circuits; fast and accurate safety distance calculation enables management and operators to quickly make decisions on whether to perform operations, thereby improving the efficiency of operation preparation and execution; software evaluation tools replace part of the on-site survey work, reducing the workload of on-site operators and reducing the cost and risk of on-site surveys; automated safety distance calculation reduces the time of manual calculations, making the evaluation process faster and improving overall work efficiency.

[0111] See also Figure 5 , Figure 5 A schematic flow chart of a conductive wire hanging ladder operation safety assessment method provided in an embodiment of the present application, the conductive wire hanging ladder operation safety assessment method can be executed in the conductive wire hanging ladder operation safety assessment device described above, and specifically may include the following steps:

[0112] S1. Obtain basic data and basic judgment conditions through the software interface;

[0113] S2. Calculate the corresponding ladder operation safety distance based on the input basic data and basic judgment conditions through the back-end calculation model;

[0114] S3. Compare the safety distance of the ladder operation with the preset safety distance threshold to determine whether the safety distance of the ladder operation is qualified and obtain a safety judgment result;

[0115] S4. Display the safety judgment result through the software interface.

[0116] Specifically, first, through the software interface, the user inputs all necessary basic data and basic judgment conditions, which include ground wire parameters, meteorological conditions, load conditions, etc., and the judgment conditions involve operation type, environmental judgment, etc. Then, the back-end calculation model is used to calculate the safe distance of the ladder operation based on the input basic data and basic judgment conditions. Next, the calculated safety distance is compared with the preset safety distance threshold to determine whether the operation is safe. Finally, the safety judgment results are displayed through the software interface, allowing users to intuitively understand the safety of the operation.

[0117] This embodiment reduces human errors and improves the accuracy of safety assessments through an automated calculation process; accurate safety distance assessment helps ensure that workers maintain a sufficient safety distance from live wires or crossing objects, thereby reducing the risk of electric shock and short circuits; fast and accurate safety distance calculations enable management and workers to quickly make decisions on whether to perform operations, thereby improving the efficiency of job preparation and execution; software assessment tools replace part of the on-site survey work, reducing the workload of on-site workers and reducing the cost and risk of on-site surveys; automated safety distance calculations reduce the time for manual calculations, making the assessment process faster and improving overall work efficiency.

[0118] In a specific embodiment, this embodiment also provides a specific implementation method of the safety assessment method for the conductive wire hanging ladder operation, and the specific process is as follows:

[0119] When the software is started, it will determine whether the software is authorized based on the computer's hardware information. If it is not authorized, you need to enter the authorization code for authorization before entering the software interface. Through the software interface, the complex coefficient judgment conditions and calculation formulas are implemented and solidified into calculation models with program codes. By entering simple basic data and basic judgment conditions, and then calling the back-end calculation model, the safe distance during ladder operation can be accurately obtained. Then, based on the safe distance of the ladder operation and the safe distance specified in the regulations, the system automatically determines whether the safety distance is qualified.

[0120] Among them, Figure 6 As shown, the software calculation process in this embodiment is as follows:

[0121] Calculate the sag at any point x under non-uniform load: fill in the constant span (m), the height difference between the adjacent tower conductor suspension points (m), and the height difference angle can be calculated according to the formula; then according to the horizontal distance between any point on the conductor and the low suspension point (m), the application of the conductor under certain meteorological conditions (Mpa), and the comprehensive specific load (Mpa / m), the sag at any point x under non-uniform load can be obtained through the back-end calculation formula model.

[0122] Calculate the safe distance when working with a hanging ladder: fill in the constant safety distance under normal working conditions (m), the wire sag under normal working conditions (m), the height of the hanging ladder (including workers, tools, and materials) (m), and the sag at any point x under the non-uniformly distributed load calculated above, and obtain the safe distance when working with a hanging ladder through the back-end calculation formula model.

[0123] Determine the safety distance: Fill in the safety distance (m) specified in the regulations and the safety distance (m) calculated for ladder operation to determine whether the safety distance during operation is qualified. If the safety distance (m) during ladder operation is ≥ the safety distance (m) specified in the regulations, the output prompt is qualified and displayed in green font; if the safety distance (m) during ladder operation is < the safety distance (m) specified in the regulations, the output prompt is unqualified and displayed in red font.

[0124] The comprehensive load ratio is a value calculated by other parameters. Therefore, when calculating the comprehensive load ratio, you need to select whether there is ice on the software interface and fill in the corresponding calculation constants.

[0125] When there is no ice: Based on the conductor’s deadweight load (Mpa / m) and the ice-free wind pressure load (Mpa / m), the comprehensive load ratio is obtained through the background calculation formula model.

[0126] Wire deadweight load (Mpa / m): obtained by filling in the constant wire mass per unit length (kg / km), wire cross-sectional area (mm2), gravity acceleration, and the back-end calculation formula model;

[0127] Ice-free wind pressure load ratio (Mpa / m): By filling in the wind load adjustment coefficient (determine the voltage level and wind speed in the system to obtain the corresponding value), wind speed uniformity coefficient (determine the wind speed in the system to obtain the corresponding value), overhead line shape coefficient (determine the conductor outer diameter in the system to obtain the corresponding value), conductor outer diameter (mm), wind speed (m / s), wind pressure (Pa) (calculated by the system based on wind speed), and the angle between wind direction and conductor, it can be obtained through the back-end calculation formula model.

[0128] When covered with ice: Based on the conductor’s deadweight load (Mpa / m), ice weight load (Mpa / m), and ice-covered wind pressure load (Mpa / m), the comprehensive load ratio is obtained through the background calculation formula model.

[0129] Wire deadweight load (Mpa / m): obtained through the wire mass per unit length (kg / km), wire cross-sectional area (mm2), gravity acceleration, and the back-end calculation formula model;

[0130] Ice weight specific load (Mpa / m): obtained through the conductor cross-sectional area (mm2), conductor outer diameter (mm), ice thickness (mm), and the back-end calculation formula model;

[0131] Icing wind pressure load ratio (Mpa / m): obtained by the icing wind load increase coefficient (determine the ice thickness in the system to obtain the corresponding value) and then fill in the constant parameters in the ice-free wind pressure, and the back-end calculation formula model.

[0132] To sum up, the safety assessment method for the conductive wire hanging ladder operation provided in this embodiment reduces the risk of accidents caused by misjudgment of safety conditions by accurately and automatically calculating the safe distance of the ladder operation, effectively protects the life safety of the operators, and improves the accuracy and efficiency of the safety assessment during the conductive wire hanging ladder operation through an automated calculation process.
