[0034] In this embodiment, the terminal constructs an electric field operation model in the electric field structure model based on the risk distribution information.

[0035] Based on the above scheme, by identifying the structural material data of the electric field structure, the structural material data of each electric field structure in the electric field area is analyzed, and the conductive radiation distribution information of each electric field structure is analyzed from the structural material data of each electric field structure, so that the conductive performance and electromagnetic radiation range of each electric field structure can be identified based on the physical properties of each structural material of the electric field structure, so as to avoid the inefficiency and low precision of manual analysis and manual collection. Afterwards, the terminal adjusts the electric field structure model of each electric field structure through the conductive radiation distribution information of each electric field structure, so that the obtained electric field structure model can better simulate the electric field operation state of the electric field under different working conditions, so as to comprehensively analyze the risk distribution information of the electric field area under different working conditions to construct an electric field operation model. Thereby improving the applicability of constructing an electric field operation model.

[0036] Optionally, based on the physical property information of each electric field structure, structural material data of each electric field structure is identified, including: for each electric field structure, based on the physical property information of the electric field structure, identifying the structural material information of each substructure of the electric field structure and the structural composition of each substructure; identifying the structural material type of each structural material information, and querying the material physical data of each structural material type and the material electromagnetic data of each structural material type in a database; based on the structural composition of each substructure and the material physical data of the structural material type of each substructure, identifying the structural support data of the electric field structure, and based on the structural composition of each substructure and the material electromagnetic data of each substructure, identifying the interactive electromagnetic data of the electric field structure; using the structural support data of the electric field structure and the interactive electromagnetic data of the electric field structure as the structural material data of the electric field structure.

[0037] In this embodiment, the terminal identifies the structural material information of each substructure of the electric field structure and the structural composition of each substructure for each electric field structure based on the physical property information of the electric field structure. The structural material information includes supporting structural materials, conductive structural materials, resistive structural materials, and radiation-proof structural materials. Each structural material includes, but is not limited to, various types of materials such as metal materials, non-metallic materials, environmentally friendly materials, and new structural materials. The structural material information of each material includes the conductive information, support information, resistance information, electromagnetic radiation information, etc. of the material.

[0038] Then, the terminal identifies the structural material type of each structural material information, and queries the material physical data of each structural material type and the material electromagnetic data of each structural material type in the database. Among them, the material physical data is the support data, conductive data, resistance data, noise generation data, etc. of the material. The material electromagnetic data is the electromagnetic radiation, electromagnetic radiation prevention and control data, etc. of the material. The structural composition of each substructure includes, but is not limited to, wrapping and covering composition, splicing composition, linking composition, wireless connection composition, etc.

[0039] Then, the terminal identifies the structural support data of the electric field structure based on the structural composition of each substructure and the material physical data of the structural material type of each substructure, and identifies the interactive electromagnetic data of the electric field structure based on the structural composition of each substructure and the material electromagnetic data of each substructure.

[0040] Finally, the terminal uses the structural support data of the electric field structure and the interactive electromagnetic data of the electric field structure as the structural material data of the electric field structure, wherein the interactive electromagnetic data includes the conductive influence information between each substructure and the electromagnetic radiation influence information between each substructure.

[0041] Based on the above scheme, the structural support data of the electric field structure and the interactive electromagnetic data are identified, thereby identifying the structural material data of the electric field structure, thereby improving the comprehensiveness of the identification.

[0042] Optionally, based on the structural material data of each electric field structure, the conductive radiation distribution information of each electric field structure is identified, including: based on the structural support data of the electric field structure, the structural support information between the substructures of the electric field structure is identified, and based on the structural support information between the substructures, in each preset position information of the electric field structure, the position information of the non-support position range is screened; based on the interactive electromagnetic data of the electric field structure, the current transmission data of each position information of the electric field structure and the electromagnetic radiation data of each position information of the electric field structure are identified; and the current transmission data of each position information and the electromagnetic radiation data of each position information are respectively distributed and arranged to obtain the conductive radiation distribution information of the electric field structure.

Among them, the terminal presets multiple position information, and the interval distance between each position information is the same, which is used to perform fine granularity recognition of the electric field structure, thereby improving the comprehensiveness and accuracy of the recognition. Secondly, screening the position information of the non-support position range can not only reduce the number of position information that needs to be analyzed, but also improve the analysis efficiency and reduce the analysis energy consumption. Then, screening the position information of the non-support position range improves the analysis accuracy of the electromagnetic data, conductive data, and noise data of the analyzed position information and other data related to power transmission risks.

[0044] Finally, based on the interactive electromagnetic data of the electric field structure, the terminal identifies the current transmission data of each position information of the electric field structure and the electromagnetic radiation data of each position information of the electric field structure. Then, the terminal performs distribution and arrangement processing on the current transmission data of each position information and the electromagnetic radiation data of each position information to obtain the conductive radiation distribution information of the electric field structure.

[0045] Based on the above scheme, the conductive radiation distribution information of the electric field structure is obtained by distributing the interactive electromagnetic data of each electric field structure at each position information, thereby improving the comprehensiveness and accuracy of identifying the conductive radiation distribution information of the electric field structure.

[0046] Optionally, based on the conductive radiation distribution information of each electric field structure, the electric field structure model is improved to obtain an electric field simulation model, including: based on the conductive radiation distribution information of each electric field structure, the conductive radiation distribution information of each electric field structure is projected into the electric field structure model to obtain an initial electric field simulation model; based on the current transmission data and electromagnetic radiation data of each position point in the initial electric field simulation model, the electromagnetic simulation parameters of each position point are identified through a simulation parameter conversion program; the electromagnetic simulation parameters of each position point are added to the initial electric field simulation model to obtain an electric field simulation model.

[0047] In this embodiment, the terminal projects the conductive radiation distribution information of each electric field structure into the electric field structure model based on the conductive radiation distribution information of each electric field structure to obtain an initial electric field simulation model. Then, based on the current transmission data and electromagnetic radiation data of each position point in the initial electric field simulation model, the terminal identifies the electromagnetic simulation parameters of each position point through a simulation parameter conversion program. Finally, the terminal adds the electromagnetic simulation parameters of each position point to the initial electric field simulation model to obtain an electric field simulation model. Among them, the simulation parameter conversion program is a parameter conversion program corresponding to the COMSOL Multiphysics software.

[0048] Based on the above scheme, the accuracy of the obtained electric field simulation model is improved by projecting the conductive radiation distribution information onto the electric field structure model and performing parameter conversion.

[0049] Optionally, based on the electric field simulation model, various simulation strategies are used to simulate the electric field operation process under various working conditions to obtain risk distribution information of the electric field area, including: obtaining the electric field current transmission data of the electric field under various working conditions and the electric field environment data of each working condition, and adjusting each electric field simulation model based on the electric field environment data of each working condition to obtain a working condition simulation model corresponding to each working condition; in the database, querying the operation data of each electric field structure in the electric field area corresponding to each working condition, and based on the operation data of each electric field structure corresponding to each working condition and the electric field current transmission data of each working condition, through the working condition simulation model corresponding to each working condition, simulate the electric field operation process under each working condition to obtain the simulated electric field operation data corresponding to each working condition; for each working condition, based on the simulated electric field operation data corresponding to the working condition, identify the sub-risk distribution information of each electric field operation risk type, and use the sub-risk distribution information of all electric field operation risk types corresponding to the working condition as the risk distribution information of the electric field area.

[0050] In this embodiment, the terminal obtains the electric field current transmission data of the electric field in each working condition and the electric field environment data of each working condition, and adjusts each electric field simulation model based on the electric field environment data of each working condition to obtain the working condition simulation model corresponding to each working condition. Among them, the electric field environment data includes but is not limited to environmental data such as environmental electromagnetic interference, environmental humidity, and environmental dryness.

[0051] In the database, the terminal queries the operating data of each electric field structure in the electric field area corresponding to each working condition, and based on the operating data of each electric field structure corresponding to each working condition and the electric field current transmission data of each working condition, the terminal simulates the electric field operation process under each working condition through the working condition simulation model corresponding to each working condition, and obtains the simulated electric field operation data corresponding to each working condition. Finally, for each working condition, the terminal identifies the sub-risk distribution information of each electric field operation risk type based on the simulated electric field operation data corresponding to the working condition, and uses the sub-risk distribution information of all electric field operation risk types corresponding to the working condition as the risk distribution information of the electric field area. Among them, the electric field operation risk types include, but are not limited to, the risk type of electric shock caused by potential difference, the risk type of physical injury caused by electromagnetic radiation, the risk type of working state interference caused by noise interference, the risk type of high temperature burns of wires caused by excessive current, etc.

[0052] Based on the above solution, by adding the electric field environment data, the risk distribution information is identified for each working condition, which improves the comprehensiveness and accuracy of the risk distribution information of the identified electric field area.

[0053] Optionally, based on the risk distribution information, an electric field operation model is constructed in the electric field structure model, including: based on the sub-risk distribution information of each electric field operation risk type corresponding to each operating condition, marking each risk range of each electric field operation risk type and the risk data corresponding to each risk range in the electric field structure model to obtain the sub-electric field operation model corresponding to each operating condition; and using the sub-electric field operation models corresponding to all operating conditions as the electric field operation model.

[0054] In this embodiment, based on the sub-risk distribution information of each electric field operation risk type corresponding to each working condition, the terminal marks each risk range of each electric field operation risk type and the risk data corresponding to each risk range in the electric field structure model to obtain the sub-electric field operation model corresponding to each working condition. Finally, the terminal uses the sub-electric field operation models corresponding to all working conditions as the electric field operation model.

[0055] Based on the above scheme, the comprehensiveness of the obtained electric field operation model and the accuracy of risk marking are improved by marking the sub-risk distribution information of each electric field operation risk type.
