[0002] In modern power engineering, building power distribution and other fields, cable design, as one of the basic tasks of the power system, shoulders the important responsibility of ensuring the safe operation of electrical equipment. Cable design involves the selection of multiple parameters, including cable type, voltage level, current-carrying capacity, laying method, etc. These design parameters must meet multi-level specification requirements. Common specifications include national standards, industry specifications, and internal technical rules of each enterprise. The provisions of these specifications directly affect the safety, reliability, and economy of cable design. Due to different requirements and constraints among various levels of specifications, cable designers need to conduct cumbersome comparison and verification during the design process to ensure that the design meets all standards.
[0003] However, due to the complexity and continuous update of specification content, manual comparison is prone to omissions or errors. Especially in large projects, it may lead to designs that do not meet specification requirements, thereby causing construction risks and safety hazards. Therefore, how to achieve intelligent matching and verification between cable design parameters and multiple specifications during the design stage has become a key issue for improving design quality, reducing project risks, and enhancing work efficiency. The present invention comes into being, aiming to solve the problems of multi-specification integration and compliance verification in cable design through an automated and intelligent approach.
[0004] The prior art has at least the following technical problems: The prior art mostly adopts a verification method based on a single specification, which cannot effectively integrate design requirements from multiple sources and levels, and is prone to overlooking certain implicit conflicts or misalignments, resulting in design results that do not fully meet all specification requirements, and may even cause design safety hazards and project delays; The traditional design optimization process lacks intelligent means and cannot automatically generate an optimal design plan that meets the specifications, increasing the complexity and workload of manual intervention, and reducing the overall design efficiency and quality. Summary of the Invention

[0020] Refer to Appendix Figure 2 , which shows a flowchart of a cable design verification method provided by an embodiment of the present invention. The method includes the following steps: S1. Construct a multi-level cable design specification library, obtain a specification tensor through structured modeling, combine the design parameters with the specification tensor, construct a constraint function, and quantify the cross-influence between multi-level and multi-source specifications; Import structured parameter information including cable model, rated voltage, laying method, laying path length, design current-carrying capacity, etc. from the design platform (such as CAD or BIM system) through an interface. At the same time, manual input or batch import of Excel / CSV format data is allowed to ensure the unity and standardization of the data source. All collected parameters will be mapped into a parameter vector according to the standardized format and automatically bound to the index items in the specification clauses, thus providing an accurate input basis for the tensor construction process, avoiding human matching deviation, and ensuring the stability and engineering adaptability of the algorithm operation.
[0021] Build a multi-level cable design specification library, covering national standards, industry specifications, and enterprise internal rules. Use rule engine technology to automatically compare design parameters, such as cable models, current-carrying capacities, voltage withstand levels, and laying methods. By establishing mathematical relationships between each design parameter in the specification and the corresponding constraint conditions and context environment, construct a multi-level specification tensor to express the misalignment, interaction, and constraint relationships of cable design parameters among different specifications; each element in the tensor represents the constraint strength or control effect of a certain design parameter under a specific specification in a specific context environment. Through structured modeling, multiple constraint levels from different specifications can be integrated into a unified tensor structure, enabling specifications from different sources to be compared and analyzed within the same framework. Each dimension and coefficient of the tensor reflect the degree of interaction and influence among the three dimensions of parameters, constraints, and environment in the current specification. The construction formula of the specification tensor is as follows: ; where, is a three-dimensional specification tensor representing the interaction strength among cable design parameters, specification sources, and constraints. Each dimension corresponds to a different attribute: i represents the ordinal number of a specific parameter in cable design (such as current-carrying capacity, voltage level, etc.), j represents the ordinal number of the constraint rule of parameter i in a certain specification (such as national standard, industry standard, enterprise standard, etc.), and k represents the ordinal number of context environment factors (such as temperature, laying method, etc.); represents the specification importance coefficient of the i-th design parameter in the n-th layer of the specification, reflecting the control strength of the i-th design parameter in the standard, which can be obtained by statistically counting the frequency of the current parameter in the standard and normalizing it; represents the absolute control weight of the j-th constraint rule in the n-th layer of the specification, which is assigned by experts or calculated by weighting the complexity of standard clauses (such as formula length, number of limiting conditions); is the k-th context adaptation factor in the n-th layer of the specification, indicating the degree of influence of the environment on the effectiveness of the design parameter, with a value range of [0,1], which can be fitted through the environmental adaptation coefficient of historical projects; represents the misalignment sensitivity between the i-th design parameter and the j-th constraint rule, reflecting the perturbation degree caused by inconsistent definitions under different specification versions, obtained through version text similarity analysis and multiplied by the difference sign matrix; is the integration weight of the n-th layer of the specification, with the national standard being the largest, the industry standard being the second, and the enterprise specification being the smallest.
[0022] Different specification constraints are converted into mathematical expressions and applied to the design parameter space to construct a multidimensional constraint function. The input design parameters are combined with the specification tensor to indicate the degree to which the design parameters under specific constraints do not meet the specifications. The constraint function accurately quantifies the impact of constraints in different levels of specifications on the design scheme by including multiple factors such as cable parameters, specification control weights, and specification error sensitivity.
[0023] Specifically, the square term of the design parameter is multiplied by each weight coefficient in the specification tensor to represent the quadratic constraint between the design parameter and the specification tensor; the second term describes the mutual influence between the design parameters by introducing a logarithmic function of the difference between the design parameters, and assigns different adjustment weights according to the flexibility of the specification; the combination of constraint functions ensures that the cross-influence between multi-level and multi-source specifications can be effectively quantified. Its mathematical expression is: ; in, It is The specification constraint function is used to describe the relationship between the design parameter vector P and the specification tensor Under the normative constraints Compliance impact on design parameters; Used to describe the effect of design parameters on code constraints, is the forcing coefficient, indicating the The mandatory influence of the specification constraint on the i-th design parameter under the j-th constraint rule and the k-th context environment condition is obtained through expert experience, data regression or literature analysis. is the i-th design parameter; is the linkage influence coefficient, which represents the influence of the jth constraint rule on the ith design parameter and the kth contextual environment condition. It is used to quantify the influence of the constraint rule on the nonlinear relationship between the design parameters. Its empirical value can be obtained by performing eigenvalue processing on the covariance matrix of the project history sample parameters through the regression method. and are the design parameters under the jth constraint rule and the kth context environment conditions, such as voltage and current carrying capacity; It is The upper limit of the target value constrained by the specification is directly derived from the specification limit or engineering experience value.
[0024] S2. Define the interference function to quantify the degree of conflict between any two specification constraints in the cable design parameter space. Use the gradient field of the interference function in the path search process to optimize the adjustment path of the cable design parameters and calculate the optimal design adjustment path. By minimizing the mapping optimization objective function, the optimal design parameter adjustment solution is obtained, thereby achieving compliance optimization of the cable design.
[0025] To accurately quantify the conflict degree between any two specification constraints in the cable design parameter space, it is necessary to define an interference degree function that reflects the difference strength of the constraint functions, calculate the integral value of the squared difference of the two specification constraints in the entire design parameter space, and normalize it by the product of the gradient norms of the two, so as to reflect the numerical deviation and structural similarity between the specification constraints.
[0026] Specifically, the numerator part captures the squared difference of the values of the two constraint functions at all feasible points in the parameter space through integration, representing the total energy of the function deviation in the entire design domain; while the denominator part calculates the product of the first-order gradient norm moduli of the two constraint functions, which is used to measure the sensitivity difference in the changing trend. The interference degree function comprehensively reflects whether the two constraints coincide in the spatial structure, whether the function values converge, and whether the change responses are consistent. The formula is as follows: ; Among them, is the th specification constraint and the qth specification constraint The conflict measure on the design parameter space P, that is, the interference degree between the two constraints, reflects the degree of inconsistency between the two constraints in the parameter space; is the design parameter space, representing all possible design parameter combinations; and respectively represent the gradients of the specification constraint and the specification constraint on the design parameter space, indicating the response sensitivity of the design parameter fine-tuning to the specification value; is a constant to prevent numerical instability caused by the denominator being zero, generally taking 10 -6 . The interference degree function The partial derivatives of the interference degree function with respect to each design parameter form the interference degree function gradient field .
[0027] The interference degree function gradient field is used in the path search process. The path refers to the adjustment process from the initial design state to the final optimized design state in the design parameter space; in the path search process, in order to optimize the adjustment path of the cable design parameters, it is necessary to calculate the cost generated each time when transferring from the current state to the next state, design a cost function, which includes two parts: the first part represents the interference increment caused by the design parameter adjustment, reflecting the conflict change between different constraints in the design space; the second part is the physical distance measure between the design parameters, which is used to control the smoothness of the design parameter adjustment and avoid the design instability caused by too large adjustment amplitude. The cost function combines the needs of conflict increase and adjustment smoothness to obtain the cost of each path conversion. The path cost function is constructed as follows: ; Among them, is the total cost from state to state , including the conflict cost and the adjustment cost. is the design state corresponding to the design parameter at time step t; is the cable design parameter vector at time t; is the smoothing coefficient, which is used to control the smoothness of the design parameter adjustment path; represents the square of the Euclidean distance of the design parameter from to , that is, the total change amplitude between the design parameters.
[0028] The one with the minimum total cost among all paths is selected as the optimal path, which is the best adjustment trajectory that can be executed during the design process. The expression is: ; Among them, is the optimal design adjustment path. That is, among all possible adjustment paths, which path has the minimum total cost (i.e., the sum of the costs of all design adjustments), representing the best adjustment order from the initial design to the final optimized design; is the set of all possible paths, that is, all parameter paths from the initial design to the final optimized design; T is the path length (i.e., the total number of time steps).
[0029] Based on the generated optimal path, a mapping optimization objective function is established to select the optimal design parameter fine-tuning mapping, further correct the design parameters and ensure compliance with the specifications; in order to select the optimal adjustment mapping, the objective function is defined by comprehensively considering the optimal path tracking deviation and the interference degree after adjustment. By minimizing the objective function, the optimal adjustment mapping is ensured to be obtained, thereby realizing the compliance optimization of the cable design. The objective function is constructed as follows: ; ; Among them, is the objective function, which is used to calculate the overall cost of the design parameter adjustment, aiming to measure the deviation and conflict of the given adjustment path relative to the optimal design adjustment path , is an optional adjustment path, representing the adjustment path from the initial design to the optimized design; is the optimal adjustment function, representing the optimal design parameter adjustment scheme found through the mapping optimization process; is the parameter vector of the adjusted design parameter adjustment path at time step t, that is, on the optimal design adjustment path The design parameters adjusted on the basis of are obtained through optimization algorithms (such as path search optimization or adjustment algorithms). is the path fidelity weight coefficient, which controls the stability of path adjustment. is the conflict suppression weight coefficient, which controls the reduction intensity of specification conflicts during the adjustment process (i.e., reduces specification inconsistencies) and is set according to the engineering safety factor strategy; A is the set of all feasible paths, including all possible design parameter adjustment sequences. represents the square of the Euclidean distance between the adjusted path and the optimal design adjustment path, which is used to measure the difference between the two, and the goal is to minimize the deviation of path adjustment. Quantifies the intensity of specification conflicts generated after adjustment, and evaluates the compliance of design parameters after adjustment with specifications through the interference function.
[0030] Apply the optimal design parameter adjustment scheme to various relevant parameters of cable design, such as cable type, voltage level, current-carrying capacity, laying method, etc., and make fine-tuning according to the optimization suggestions to ensure effective constraints and verifications under each layer of specifications (national, industrial, and enterprise standards) and meet the requirements of various specifications.

The output interference degree function will be transferred to the path optimization module; The path optimization module conducts path search based on the interference degree calculation result to determine the best path for design parameter adjustment, optimizes the adjustment path of cable design parameters by calculating the cost generated each time transferring from the current state to the next state, ensures that the cost of each adjustment is minimized, and the generated optimal path will be transferred to the adjustment mapping module; Adjustment mapping module, based on the optimal path optimization result, establishes a mapping optimization objective function, selects the optimal fine-tuning scheme for design parameters, calculates the overall cost of design parameter adjustment, comprehensively considers the stability of path adjustment and the reduction of specification conflicts, and finally obtains the optimal adjustment scheme to ensure that the design scheme meets all specification requirements.
