Description

Technical Field

[0001] The present invention relates to the technical field of optical cable laying, and in particular to a three-dimensional collaborative design system and method for optical cables in intelligent substations. Background Art

[0002] Optical cable is a communication transmission line that combines optical fiber and cable. In modern communication networks, optical cables are widely used in long-distance communication and metropolitan area network construction. The optical fiber part can achieve high-speed data transmission, such as the transmission of Internet data, high-definition video signals, etc. The cable part can be used to transmit electricity, provide power for communication equipment, or be used to transmit some low-frequency control signals.

[0003] With the rise of digital technology, three-dimensional modeling technology has been gradually applied to the field of substation optical cable laying, improving the shortcomings of traditional two-dimensional optical cable laying design to a certain extent.

[0004] Publication No. CN110442992B relates to an electromechanical collaborative design method and device for aerospace system cable networks. Through a three-dimensional design module, the problem of unclear expression or large discrepancies with actual conditions when there are special assembly requirements is solved, and the matching of cable parameter information and three-dimensional models is achieved, thereby improving the precision of cable network layout.

[0005] However, the above application still has the following problems: When 3D modeling technology is applied to the design of optical cable laying in substations, optical cable design involves massive data, including multi-source data of electrical performance parameters, mechanical properties, and laying environment information. When integrating these data, data conflicts are frequently encountered. Currently, there is a lack of effective processing mechanism when facing data conflicts. When facing data conflicts, they can only be manually identified and adjusted manually, which is highly subjective. Summary of the invention

[0006] In order to solve the technical problems existing in the background technology, the present invention proposes a three-dimensional collaborative design system and method for optical cables in smart substations.

[0007] The three-dimensional collaborative design system for optical cables of smart substations proposed by the present invention comprises:

[0008] Substation 3D model generation module: used to obtain substation data and build a 3D model of the substation using 3D modeling software;

[0009] Optical cable laying 3D design module: Based on the 3D model of the substation, each professional selects the appropriate 3D design software according to their functions to realize the 3D design of optical cable laying;

[0010] Data sharing platform building module: used to build a data sharing platform to achieve real-time synchronization between 3D design software and data sharing platform. When one party modifies the data, the other party will update it immediately.

[0011] Data conflict replacement module: In the data sharing platform building module, when the platform integrates multi-source data and encounters data conflicts, the data conflict replacement module is enabled to generate fusion values ​​and replace the original conflicting data with the fusion values.

[0012] Preferably, in the data conflict replacement module, the fusion value is generated as follows:

[0013] Assume that there are i data sources of multi-source data, and each of the i data sources provides i data values: x1, x2, ..., xi, where i is a positive integer;

[0014] Scoring the reliability of i data sources:

[0015] Through the hierarchical analysis method, the reliability assessment of data sources is decomposed into multiple levels, a hierarchical structure model is established, a judgment matrix is ​​constructed, and the weight vectors of the elements at each level are calculated. Finally, the comprehensive weight of each data source, i.e., the reliability score, is obtained.

[0016] Assume that the reliability scores R of i data sources are: R1, R2, ..., Ri;

[0017] Assume that the weights w of i data sources are: w1, w2, ..., wi;

[0018] Then the initial weights of the i data sources are:

[0019]

[0020]

[0021] Then the calculation equation of the fusion value F is:

[0022] F=w1×x1+w2×x2+...+wi×xi.

[0023] Preferably, in the data sharing platform building module, when the platform integrates multi-source data and encounters data value conflicts and inconsistent data boundaries, a fuzzy logic algorithm is used to provide a fuzzy data boundary to determine whether the data with data value conflicts are all within the fuzzy data boundary. If one of the conflicting data values ​​is not within the fuzzy data boundary, the data conflict replacement module is not started. If the data with data value conflicts are all within the fuzzy data boundary, the fusion value is calculated through the data conflict replacement module, and then it is determined again whether the fusion value is within the fuzzy data boundary. If not, the fusion value is not used to replace the conflicting data value. If so, the fusion value is used to replace the conflicting data value.

[0024] Preferably, in the data sharing platform building module, before the data conflict replacement module processes the data, it divides the data into different categories, establishes an independent temporary storage area for each type of data, and sets a conflict difference threshold for each type of data. When the platform integrates multi-source data and there are conflicts and inconsistencies in the multi-source data, the maximum data value in the multi-source data with conflicts is subtracted from the minimum data value. When the difference is less than the conflict difference threshold, the data conflict replacement module is used to calculate the fusion value, and the fusion value is used to replace the original data values ​​with differences.

[0025] When the difference is greater than the conflict difference threshold, the data generation algorithm of the grey system is used to preprocess the conflicting multi-source data, and then the data conflict replacement module is used to calculate the fusion value, and the fusion value is used to replace the original data values ​​with differences.

[0026] Preferably, in the data sharing platform building module, before the data conflict replacement module processes the data, a K-Means clustering algorithm is used to cluster and divide the data into different categories according to data attributes.

[0027] Preferably, in the substation three-dimensional model generation module, the three-dimensional modeling software Revit or Bentley is used to build the substation three-dimensional model.

[0028] Preferably, it also includes:

[0029] Transmission encryption module: used for data encryption transmission in the optical cable laying three-dimensional design module and the data sharing platform construction module.

[0030] The present invention proposes a three-dimensional collaborative design method for optical cables in smart substations, comprising the following steps:

[0031] Obtain substation data and use 3D modeling software to build a 3D model of the substation;

[0032] Based on the 3D model of the substation, each professional selects the appropriate 3D design software according to their functions to realize the 3D design of optical cable laying;

[0033] Build a data sharing platform to achieve real-time synchronization between 3D design software and data sharing platform. When one party modifies the data, the other party will update it immediately.

[0034] In the data sharing platform building module, the K-Means clustering algorithm is used to cluster and divide the data into different categories according to the data attributes, and set the conflict difference threshold for each type of data;

[0035] When the platform integrates multi-source data and there are conflicts and inconsistencies in the multi-source data, the maximum data value in the conflicting multi-source data is subtracted from the minimum data value. When the difference is less than the conflict difference threshold, the data conflict replacement module is used to calculate the fusion value, and the fusion value is used to replace the original data values ​​with differences; when the difference is greater than the conflict difference threshold, the data generation algorithm of the gray system is used to pre-process the conflicting multi-source data, and then the data conflict replacement module is used to calculate the fusion value, and the fusion value is used to replace the original data values ​​with differences;

[0036] When the platform integrates multi-source data and encounters data value conflicts and inconsistent data boundaries, a fuzzy logic algorithm is used to provide a fuzzy data boundary to determine whether the data with data value conflicts are all within the fuzzy data boundary. If one of the conflicting data values ​​is not within the fuzzy data boundary, the data conflict replacement module will not be started. If the data with data value conflicts are all within the fuzzy data boundary, the data conflict replacement module will be used to calculate the fusion value, and then it will be determined again whether the fusion value is within the fuzzy data boundary. If not, the fusion value will not be used to replace the conflicting data value. If so, the fusion value will be used to replace the conflicting data value.

[0037] In the present invention, the proposed intelligent substation optical cable 3D collaborative design system and method has the following beneficial technical effects:

[0038] 1. When faced with data conflict problems when the platform integrates multi-source data, the data conflict replacement module is used to generate fusion values, and the fusion values ​​are used to replace the original data with conflicts, so as to solve the conflict problems when the platform integrates multi-source data in a targeted manner. When faced with data conflict problems when the platform integrates multi-source data and the data boundaries are inconsistent, the fuzzy logic algorithm is used to provide fuzzy data boundaries to determine whether the conflicting data meets the fusion conditions and avoid unreasonable fusion. By replacing the original data with conflicts with fusion values, a reliable basis for design decisions is provided.

[0039] 2. By clustering the data according to their attributes and dividing them into different categories, and setting a conflict difference threshold for each type of data, the data conflict replacement module is used to generate a fusion value for the conflicting data with small differences, and the fusion value is used to replace the original data with differences. The data with large differences are first pre-processed with the data generation algorithm of the gray system and then the data conflict replacement module is used to generate a fusion value to ensure the rationality of the fusion value and improve the accuracy of data fusion.

[0040] 3. Real-time data synchronization and efficient collaboration: The data sharing platform building module realizes real-time synchronization between 3D design software and data sharing platform. When one party modifies the data, the other party will update it immediately, breaking down information barriers. Each professional team can grasp the latest design dynamics in real time and adjust the plan in time, which greatly improves the efficiency of design collaboration and reduces the communication costs and design errors caused by information lag and version differences.

[0041] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Figure 2 Flow chart of the method of the present invention. DETAILED DESCRIPTION

[0044] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] like Figure 1 The three-dimensional collaborative design system for optical cables in smart substations shown in the figure includes:

[0046] Substation 3D model generation module: used to obtain substation data and build a 3D model of the substation using 3D modeling software;

[0047] In the substation 3D model generation module, the 3D modeling software Revit or Bentley is used to build the substation 3D model;

[0048] Optical cable laying 3D design module: Based on the 3D model of the substation, each professional selects the appropriate 3D design software according to their functions to realize the 3D design of optical cable laying;

[0049] Specifically, civil engineers use 3D modeling software to construct 3D models of the substation site and the main building structure, which includes the main control building, power distribution room, cable trench, and shaft;

[0050] Based on the 3D model of the substation, the primary electrical engineer implanted the equipment into the model according to the actual location and size, and used lines of different colors to preliminarily outline the direction of the power cables, visually displaying the electrical connection relationship between the equipment, including the main transformer, circuit breaker, and switch cabinet;

[0051] Communications, electrical secondary and electrical primary engineers plan optical cable routes according to their own professional needs and mark them in the 3D model. Communications engineers focus on optical fiber communication links to connect the communication equipment in the station with the monitoring center; electrical secondary engineers plan the direction of control cables around secondary equipment; electrical primary engineers improve the layout of power cables;

[0052] After determining the detailed parameters of the optical cable, the communications engineer determines the number and type of optical fiber cores, and selects products based on bandwidth and transmission distance; the electrical secondary engineer determines the number of control cable cores and shielding method; the electrical primary engineer determines the current carrying capacity adaptation and insulation level of the power cable, enters the parameters into the three-dimensional model of the substation, and generates a three-dimensional design for the optical cable laying.

[0053] In the three-dimensional design module of optical cable laying, in the optical cable laying design software, the preliminary laying route is automatically planned according to the electrical connection logic, current carrying capacity requirements, and the shortest path principle, which greatly improves the design efficiency; combined with mechanical simulation, the stress conditions of the optical cable under different working conditions are simulated, and a fixed point layout is set to prevent line damage caused by dead weight and thermal expansion and contraction, effectively enhancing the scientificity and practicality of the optical cable laying design, extending the service life of the optical cable, and reducing operation and maintenance costs.

[0054] Through the substation 3D model generation module, 3D model of the substation is constructed using 3D modeling software to lay a solid foundation for subsequent design; each profession selects suitable software according to its function to carry out 3D design of optical cable laying, and engineers of civil engineering, primary electrical engineering, communications, secondary electrical engineering, etc. divide the work and cooperate with each other, fully combining their own professional knowledge and needs to realize the refined operation of the whole process from site and main building structure construction to equipment implantation, route planning of different types of cables and parameter determination, so as to comprehensively improve the accuracy and scientificity of substation and optical cable design, and effectively avoid design errors caused by poor connection between different professions.

[0055] Data sharing platform building module: used to build a data sharing platform to achieve real-time synchronization between 3D design software and data sharing platform. When one party modifies the data, the other party will update it immediately.

[0056] Data conflict replacement module: In the data sharing platform building module, when the platform integrates multi-source data and encounters data conflicts, the data conflict replacement module is enabled to generate fusion values ​​and replace the original conflicting data with the fusion values.

[0057] Transmission encryption module: used for data encryption transmission in the optical cable laying three-dimensional design module and the data sharing platform construction module;

[0058] The transmission encryption module adopts SSL / TLS encryption; the transmission encryption module adopts SSL / TLS encryption technology to protect the data transmission between the optical cable laying three-dimensional design module and the data sharing platform construction module, strictly prevent the security risks of data leakage and tampering, consolidate the information security line of the design system, and protect the key design data of the substation and the core technology assets of the enterprise.

[0059] Obtain substation data and use 3D modeling software to build a 3D model of the substation;

[0060] Based on the 3D model of the substation, each professional selects the appropriate 3D design software according to their functions to realize the 3D design of optical cable laying;

[0061] Data sharing platform building module:

[0062] It is used to build a data sharing platform to achieve real-time synchronization between 3D design software and the data sharing platform. When one party modifies the data, the other party will update it immediately. It breaks down information barriers, and each professional team can grasp the latest design dynamics in real time and adjust the plan in time, which greatly improves the efficiency of design collaboration and reduces communication costs and design errors caused by information lag and version differences.

[0063] Data conflict replacement module: In the data sharing platform building module, when the platform integrates multi-source data and encounters data conflicts and inconsistencies, the data conflict replacement module is enabled to generate fusion values ​​and replace the original data with conflicts;

[0064] In the data sharing platform building module, when the platform integrates multi-source data and encounters data value conflicts and inconsistent data boundaries, a fuzzy logic algorithm is used to provide a fuzzy data boundary to determine whether the data with data value conflicts are all within the fuzzy data boundary. If one of the conflicting data values ​​is not within the fuzzy data boundary, the data conflict replacement module will not be started. If the data with data value conflicts are all within the fuzzy data boundary, the data conflict replacement module will be used to calculate the fusion value, and then it will be determined again whether the fusion value is within the fuzzy data boundary. If not, the fusion value will not be used to replace the conflicting data value. If so, the fusion value will be used to replace the conflicting data value.

[0065] In the data sharing platform building module, before processing the data, the data conflict replacement module divides the data into different categories, establishes an independent temporary storage area for each type of data, and sets a conflict difference threshold for each type of data. When the platform integrates multi-source data and there are conflicts and inconsistencies in the multi-source data, the maximum data value in the conflicting multi-source data is subtracted from the minimum data value. When the difference is less than the conflict difference threshold, the data conflict replacement module is used to calculate the fusion value and replace the original data values ​​with the fusion value;

[0066] When the difference is greater than the conflict difference threshold, the data generation algorithm of the grey system is used to pre-process the conflicting multi-source data, and then the data conflict replacement module is used to calculate the fusion value, and the fusion value is used to replace the original data value with differences;

[0067] Some data sequences may be incomplete or highly volatile. The data generation algorithm of the grey system is used to preprocess the conflicting multi-source data. The data conflict replacement module can fuse data based on more stable and regular data, thereby obtaining more reasonable fusion values ​​to replace the original data that may have problems.

[0068] In the data sharing platform building module, before the data conflict replacement module processes the data, the K-Means clustering algorithm is used to cluster and divide the data into different categories according to the data attributes;

[0069] The K-Means clustering algorithm is used to cluster and divide data into different categories according to data attributes, and a conflict difference threshold is set for each type of data. The data conflict replacement module is used to generate a fusion value for the conflicting data with small difference, and the fusion value is used to replace the original data with differences. The data with large difference is first preprocessed with the data generation algorithm of the gray system and then the data conflict replacement module is used to generate a fusion value to ensure the rationality of the fusion value and improve the accuracy of data fusion.

[0070] The use of K-Means clustering algorithm helps to better sort out messy multi-source data and divide data categories more clearly. Compared with simply dividing according to data attributes, it is more flexible and accurate. It enables the data conflict replacement module to better adapt to the inherent distribution law of data when dealing with data conflicts in different clusters, thereby obtaining a more reasonable fusion value.

[0071] In an optional embodiment, in the data conflict replacement module, the fusion value is generated as follows:

[0072] Assume that there are i data sources of multi-source data, and each of the i data sources provides i data values: x1, x2, ..., xi, where i is a positive integer;

[0073] Scoring the reliability of i data sources:

[0074] Through the hierarchical analysis method, the reliability assessment of data sources is decomposed into multiple levels, a hierarchical structure model is established, a judgment matrix is ​​constructed, and the weight vectors of the elements at each level are calculated. Finally, the comprehensive weight of each data source, i.e., the reliability score, is obtained.

[0075] Assume that the reliability scores R of i data sources are: R1, R2, ..., Ri;

[0076] Assume that the weights w of i data sources are: w1, w2, ..., wi;

[0077] Then the initial weights of the i data sources are:

[0078]

[0079] Then the calculation equation of the fusion value F is:

[0080] F=w1×x1+w2×x2+...+wi×xi;

[0081] The fusion value is directly fed back to the 3D collaborative design model and various professional design links to avoid design errors caused by deviations from a single data source.

[0082] When faced with data conflict problems when the platform integrates multi-source data, the data conflict replacement module is used to generate fusion values, and the fusion values ​​are used to replace the original data with conflicts, so as to solve the conflict problems when the platform integrates multi-source data in a targeted manner. When faced with data conflict problems when the platform integrates multi-source data and the data boundaries are inconsistent, the fuzzy logic algorithm is used to provide fuzzy data boundaries to determine whether the conflicting data meets the fusion conditions and avoid unreasonable fusion. By replacing the original data with conflicts with fusion values, a reliable basis is provided for design decisions.

[0083] like Figure 2 A three-dimensional collaborative design method for optical cables in smart substations is shown, comprising the following steps:

[0084] Obtain substation data and use 3D modeling software to build a 3D model of the substation;

[0085] Based on the 3D model of the substation, each professional selects the appropriate 3D design software according to their functions to realize the 3D design of optical cable laying;

[0086] Build a data sharing platform to achieve real-time synchronization between 3D design software and data sharing platform. When one party modifies the data, the other party will update it immediately.

[0087] In the data sharing platform building module, the K-Means clustering algorithm is used to cluster and divide the data into different categories according to the data attributes, and set the conflict difference threshold for each type of data;

[0088] When the platform integrates multi-source data and there are conflicts and inconsistencies in the multi-source data, the maximum data value in the conflicting multi-source data is subtracted from the minimum data value. When the difference is less than the conflict difference threshold, the data conflict replacement module is used to calculate the fusion value, and the fusion value is used to replace the original data values ​​with differences; when the difference is greater than the conflict difference threshold, the data generation algorithm of the gray system is used to pre-process the conflicting multi-source data, and then the data conflict replacement module is used to calculate the fusion value, and the fusion value is used to replace the original data values ​​with differences;

[0089] When the platform integrates multi-source data and encounters data value conflicts and inconsistent data boundaries, a fuzzy logic algorithm is used to provide a fuzzy data boundary to determine whether the data with data value conflicts are all within the fuzzy data boundary. If one of the conflicting data values ​​is not within the fuzzy data boundary, the data conflict replacement module will not be started. If the data with data value conflicts are all within the fuzzy data boundary, the data conflict replacement module will be used to calculate the fusion value, and then it will be determined again whether the fusion value is within the fuzzy data boundary. If not, the fusion value will not be used to replace the conflicting data value. If so, the fusion value will be used to replace the conflicting data value.

[0090] When the fusion value is not used to replace the conflicting data values, the traditional manual screening and manual adjustment methods are required to deal with the data conflict, rather than not processing it.

[0091] In summary, this patent application comprehensively optimizes the three-dimensional collaborative design process of optical cables for smart substations, improves design efficiency, quality and safety, and helps to promote substation construction projects efficiently and with high quality.
