Description

Technical Field

[0001] This invention relates to the field of intelligent cabling technology, and in particular to an intelligent cabling design and offline simulation verification system for substation secondary cables. Background Technology

[0002] Substation secondary cable routing design involves the integration and analysis of various data, including equipment location and channel attributes. Current technologies rely heavily on manual data collection and correlation, lacking a systematic integration mechanism. This makes it difficult to achieve accurate spatial matching of equipment and channel information. Furthermore, path planning and parameter calculation depend on the designer's experience and judgment, lacking scientific methods for the quantitative analysis of key parameters such as cable bending radius and three-dimensional spatial position, easily leading to unreasonable parameter settings. In addition, existing technologies lack comprehensive offline simulation verification methods, failing to provide full-scale virtual verification of the routing scheme and making it difficult to identify potential spatial interference problems during the routing process. Problems can only be discovered and rectified during the actual construction phase, resulting in insufficient scientific rigor and accuracy in the overall design process.

[0003] In traditional substation secondary cable routing design processes, high levels of manual intervention lead to low design efficiency. Furthermore, design errors caused by subjective judgment can easily result in routing schemes that do not match actual site conditions. This not only increases adjustment costs during construction but also affects the overall quality of cable installation and the convenience of subsequent operation and maintenance. Simultaneously, the lack of effective path optimization mechanisms often leads to temporary corrective measures for interference issues during routing, making it difficult to develop standardized, interference-free routing schemes. Consequently, the reliability and feasibility of the design outcomes cannot be effectively guaranteed. Therefore, improving the efficiency and quality of substation secondary cable routing design has become an urgent problem to be solved. Summary of the Invention

[0009] In a preferred embodiment, when the spatial deployment module performs deployment planning for the cable to be deployed, using the three-dimensional spatial location information as a deployment reference and combining it with the cable attributes of the cable to be deployed, to obtain the spatial deployment characterization of the cable to be deployed, it is specifically used for: The trajectory points of the cable to be laid are used as the spatial orientation reference for the cable to be laid. The cable properties of the cable to be laid are defined by the cable outer diameter, bending radius multiple, and weight per unit length. Based on the cable properties, the cable to be laid is divided into grids to obtain a grid of possible locations for the cable to be laid. Based on the bending radius multiple, the feasibility of bending through the grid of possible locations is determined to obtain the final location of the cable to be laid. Map the grid coordinates of the final deployment location to a three-dimensional spatial coordinate system to obtain the spatial coordinate points of the channel segment of the cable to be deployed; Connect the spatial coordinate points in directional order to obtain the spatial layout characterization of the cable to be laid.

[0010] In a preferred embodiment, the spatial deployment module performs grid-based subdivision of the cable to be deployed based on the cable attributes to obtain a grid of deployable locations for the cable, specifically for: Based on the channel identifier in the three-dimensional spatial location information, the boundary coordinates of the cross-sectional profile and the position coordinates of obstacles within the cross-section are obtained from the channel attribute information, and the boundary coordinates and the position coordinates are used as the cross-sectional shape parameters of the cable to be laid.

[0012] In a preferred embodiment, when the interference detection module performs a peripheral interference check on the cable to be laid based on the offline simulation verification scenario to obtain the interference verification characterization of the cable to be laid, it is specifically used for: An indexing rule is constructed for the offline simulation verification scenario to obtain the spatial index structure of the offline simulation verification scenario; Based on the spatial index structure, a spatial domain range search is performed on the virtual entity of the cable to be laid to obtain the spatial domain of the cable to be inspected. Based on the spatial domain of the cable to be inspected, the offline simulation verification scenario is filtered to obtain candidate interference objects for the cable to be laid. Spatial contour analysis is performed on the candidate interference object to obtain the spatial coordinate boundary of the candidate interference object; The spatial intersection of the spatial coordinate boundary with the spatial boundary coordinate of the spatial domain of the cable to be inspected is compared to obtain the comparison characterization of the cable to be laid. If the comparison indicates the existence of an intersection, then the boundary coordinates and intersection volume of the intersection region are extracted, and the boundary coordinates and intersection volume are used as the interference position and interference amount of the cable to be laid. The interference position and interference amount are correlated and recorded to obtain the interference verification characterization of the cable to be laid.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention achieves parameterized and digitalized control of the entire process of secondary cable wiring in substations through a multi-module collaborative intelligent design process. From the accurate acquisition and association of equipment location and channel attributes, to the scientific construction of path topology, and the quantitative calculation of key parameters such as bending radius and three-dimensional spatial position, all are completed through standardized algorithms and logic, which greatly improves the accuracy and efficiency of wiring parameter calculation. At the same time, the grid-based layout planning based on cable attributes makes the cable spatial layout more scientific and reasonable, effectively ensuring the adaptability of wiring design to the actual working conditions of substations.

[0014] 2. This invention enables a comprehensive virtual reconstruction of cable routing through an offline simulation verification scenario. Combined with interference detection using a spatial index structure, it can accurately identify the interference location and amount of cable routing. Then, through a verification and optimization module, it can make targeted adjustments and reconstructions to problematic paths, thus realizing offline simulation verification and interference-free optimization of the cabling scheme. This significantly improves the reliability and feasibility of the cable routing scheme. At the same time, the intelligent operation of the entire process reduces the subjective error of manual design, resulting in a dual improvement in the overall quality and efficiency of substation secondary cable routing design.

[0022] like Figure 1 The figure shown is a system architecture diagram of a substation secondary cable intelligent wiring design and offline simulation verification system provided in an embodiment of the present invention.

[0023] The intelligent wiring design and offline simulation verification system 100 for substation secondary cables described in this invention can be installed on a cloud server. In terms of implementation, it can be used as one or more service devices, or as an application installed on the cloud (e.g., a mobile service operator's server, server cluster, etc.), or it can be developed into a website. Depending on the functions implemented, the intelligent wiring design and offline simulation verification system 100 for substation secondary cables may include a data acquisition and association module 101, a topology relationship construction module 102, a parameter calculation module 103, a spatial layout module 104, an offline simulation module 105, an interference detection module 106, and a verification and optimization module 107. The module described in this invention can also be called a unit, which refers to a series of computer program segments that can be executed by the processor of an electronic device and can perform a fixed function, stored in the memory of the electronic device.

[0024] In this embodiment of the invention, in the intelligent cabling design and offline simulation verification system for substation secondary cables, each of the above modules can be implemented independently and can be called upon with other modules. This "calling" can be understood as one module connecting to multiple modules of another type and providing corresponding services to those connected modules. In the intelligent cabling design and offline simulation verification system for substation secondary cables provided by this embodiment of the invention, the applicable scope of the system architecture can be adjusted by adding modules and directly calling them without modifying the program code, achieving cluster-based horizontal expansion to quickly and flexibly expand the system. In practical applications, the above modules can be set in the same device or different devices, or they can be set in a virtual device, such as a service instance in a cloud server.

[0025] The following describes the components and workflow of the intelligent wiring design and offline simulation verification system for substation secondary cables, using specific embodiments as examples: The data acquisition and association module 101 is used to acquire the equipment location information and channel attribute information of the cable to be laid, and to associate and integrate the equipment location information and the channel attribute information to obtain the initial wiring parameters of the cable to be laid. In this embodiment of the invention, when the data acquisition and association module performs the function of acquiring the device location information and channel attribute information of the cable to be laid, and associating and integrating the device location information and the channel attribute information to obtain the initial wiring parameters of the cable to be laid, it is specifically used for: Extract the coordinates of the substation cabinets and the coordinates of the terminal blocks within the cabinets as the equipment location information of the substation; The geometric dimensions, endpoint coordinates of the routing segments, and cross-sectional shape parameters of the cable trenches, cable trays, and protective pipes in the substation are read as channel attribute information of the substation. Spatially correlate the device location information and the channel attribute information to obtain the association information of the cable to be laid; The associated information is stored in a hierarchical and categorized manner to obtain the initial wiring parameters of the cable to be laid.

[0026] The system traverses all cabinet entities from the 3D digital model of the substation, directly reading the X, Y, and Z coordinates of each cabinet in 3D space. Simultaneously, it delves into the internal hierarchical structure of the cabinets, locating the installation position of each set of terminal blocks one by one, collecting the relative coordinates of each set of terminal blocks inside the cabinet and their absolute coordinates in the overall space of the substation, and summarizing and organizing all cabinet coordinates and terminal block coordinate information to form the equipment location information of the substation.

[0027] From the civil engineering and electrical design drawings of the substation, the overall length, internal width, and depth data from bottom to top of the cable trench are read one by one. The cross-sectional dimensions of the upper and lower flanges and web of the cable tray are read. The external diameter, internal wall thickness, and overall length data of the protective pipe are read. At the same time, the starting and ending coordinates of the cable trench cable tray and protective pipe's respective routing segments are collected, as well as the rectangular or trapezoidal cross-sectional shape data of the cable trench, the trough or trapezoidal cross-sectional shape data of the cable tray, and the circular cross-sectional shape data of the protective pipe. All the above data are summarized and organized to form the channel attribute information of the substation.

[0028] Based on the spatial coordinates of the cabinets and terminal blocks in the equipment location information, the endpoint coordinates of the cable trench trays and protective pipes in the channel attribute information are matched one by one. By judging the proximity of spatial locations, the correspondence between each set of cabinet terminal blocks and the connectable cable trench trays and protective pipes is established, the spatial connection path from the cabinet terminal blocks to the channel entrance is clarified, and all correspondences and connection paths are summarized to obtain the association information of the cables to be laid.

[0029] According to the different voltage levels, cable functions, and voltage grades of the substation, the associated information is divided into layers. Then, according to the channel type of the cable trench, cable tray, and protective pipe, the layered information is further classified. All the classified information is stored according to the preset data structure to ensure that each piece of information corresponds to the specific equipment channel and cable type, thus obtaining the initial wiring parameters of the cable to be laid.

[0030] The beneficial effects are that by directly and accurately collecting the coordinates of the cabinet terminal blocks and the full-dimensional attribute information of the channels from the 3D model and design drawings, the errors and omissions of manual measurement are avoided. The established spatial correspondence realizes the seamless connection between equipment and channel information. The hierarchical and classified storage method makes the initial wiring information clear and searchable, providing complete and reliable data support for subsequent cable path planning, interference detection and optimization adjustment, and significantly improving the accuracy and efficiency of substation secondary cable wiring design.

[0031] The topology construction module 102 is used to perform a traversal analysis of the channel occupancy status of the cable to be laid based on the initial wiring parameters, obtain the matching channel of the cable to be laid, and determine the path topology of the cable to be laid based on the matching channel. In this embodiment of the invention, when the topology construction module performs a traversal analysis of the channel occupancy status of the cable to be laid based on the initial wiring parameters to obtain the suitable channel of the cable to be laid, and determines the path topology of the cable to be laid based on the suitable channel, it is specifically used for: The channel attribute information of the cable to be laid is parsed and mapped to obtain the physical connection relationship of the channel attribute information; Using the channel segments of the channel attribute information as nodes and the physical connection relationships as edges, construct the topology connectivity graph of the cable to be laid; Based on the topology connectivity graph, the path of the cable to be laid is filtered to obtain the suitable channel for the cable to be laid. The identification information and sequential connection relationship in the adapter channel are stored in a structured manner to obtain the path topology of the cable to be laid.

[0032] The channel attribute information contained in the initial wiring parameters is analyzed in all dimensions. The actual connection ports and connection routes of each channel segment in the cable trench, cable tray and protective pipe are sorted out. The actual connection between each channel segment is mapped and restored one-to-one, and the actual connection status between all channel segments is fully presented, so as to obtain the physical connection relationship of the channel attribute information.

[0033] Each independent cable trench segment, cable tray segment, and protective pipe segment in the channel attribute information is extracted as a basic unit. Each basic unit is set as an independent node in the topology connectivity graph. The connectivity between each channel segment in the physical connection relationship is set as the edge connecting each node. According to the actual connection order and positional relationship of each channel segment, all nodes and edges are combined in an orderly manner to build a topology connectivity graph of the cable to be laid that can completely reflect the overall connectivity of the channel.

[0034] Based on the deployment requirements of the cable to be laid, a full traversal of all complete paths consisting of nodes and edges in the topology graph is performed. The current occupancy and available space of each channel segment in each path are checked. Paths with occupancy conflicts or insufficient space are eliminated. Complete paths that fully meet the cable deployment space requirements and connectivity requirements are selected. All channel segments contained in the path are integrated to obtain the suitable channel for the cable to be laid.

[0035] Extract the unique identifier information of each channel segment in the adapter channel, sort out the sequential connection order and connection position information between each channel segment in the adapter channel, and enter and store the unique identifier information and sequential connection relationship in an orderly manner according to the preset structured data format to ensure that the identifier and connection relationship of each channel segment correspond one by one and can be quickly retrieved, so as to obtain the path topology relationship of the cable to be laid.

[0036] The beneficial effects are that by parsing and mapping the channel attribute information, the real physical connection relationship is restored, so that the construction of the topology connectivity graph has a precise actual basis. The path filtering based on the topology connectivity graph can quickly locate the matching channel that meets the deployment requirements, avoiding the time-consuming filtering of invalid paths. The structured storage of the matching channel identifier and connection relationship makes the path topology relationship clear and can directly provide an orderly path basis for subsequent parameter calculation, which greatly improves the scientificity and efficiency of cable path planning, while ensuring the accuracy and reusability of the path topology relationship.

[0037] The parameter calculation module 103 is used to quantify and analyze the spatial morphological constraints of the cable to be laid based on the path topology relationship, so as to obtain the bending radius parameter and three-dimensional spatial position information of the cable to be laid. In this embodiment of the invention, when the parameter calculation module performs quantification and analysis of the spatial morphological constraints of the cable to be laid based on the path topology relationship to obtain the bending radius parameter and three-dimensional spatial position information of the cable to be laid, it is specifically used for: Based on the path topology, the endpoints of the channel segment of the cable to be laid are calibrated to obtain the centerline endpoint coordinates of the cable to be laid. Based on a preset fixed step size, the intermediate points of the adjacent endpoints of the center line endpoint coordinates are inserted to obtain the encrypted cable trajectory points of the cable to be laid, and the three-dimensional coordinates of the encrypted cable trajectory points are used as the three-dimensional spatial position information of the cable to be laid. Neighborhood curvature clustering analysis is performed on the trajectory points of the encrypted cable to obtain the bend feature points of the cable to be laid. The feature points of the bend are fitted and merged to obtain the bend segment of the cable to be laid, and the coordinates of the starting point, the middle point and the ending point of the bend segment are extracted. The bending radius parameter of the cable to be laid is calculated based on the coordinates of the starting point, the intermediate point, and the ending point of the curved section.

[0038] The formula for calculating the bending radius parameter is as follows: ; in, The bending radius parameter is... The coordinate vector of the starting point coordinates. Let be the coordinate vector of the intermediate point. The coordinate vector of the endpoint coordinates. Let be the magnitude of the vector.

[0039] Based on the connection sequence and spatial position of each channel segment in the path topology, the spatial endpoints of each independent cable trench segment, cable tray segment, and protective pipe segment are accurately marked, the starting and ending spatial positions of the centerline of each channel segment are determined, these spatial positions are converted into corresponding three-dimensional coordinate information, and the relevant coordinate information of all channel segments is summarized to obtain the coordinates of the centerline endpoints of the cable to be laid.

[0040] A unified preset fixed step size is determined. Using this step size as the spacing standard, several spatial intermediate points are inserted sequentially between every two adjacent endpoints in the coordinates of the centerline endpoints. All the inserted intermediate points and the original centerline endpoints together form the encrypted cable trajectory points of the cable to be laid. The three-dimensional coordinates of the X-axis, Y-axis and Z-axis of each encrypted cable trajectory point are extracted. The three-dimensional coordinates of all encrypted cable trajectory points are integrated to obtain the three-dimensional spatial position information of the cable to be laid.

[0041] For each encrypted cable trajectory point, its corresponding spatial neighborhood is defined, the curvature value of the curve formed by all encrypted cable trajectory points within the neighborhood is calculated, encrypted cable trajectory points with curvature values ​​within the same feature interval are aggregated and classified, key points that can reflect the bending characteristics of the cable path are selected, and all key points are summarized to obtain the bending feature points of the cable to be laid.

[0042] The curve feature points are arranged in an orderly manner according to the continuity of spatial location. The curve feature points on the same curve path are merged and combined by curve fitting to form an independent curve segment that can completely reflect the curve direction of the cable. The spatial points of each curve segment are defined, and the starting spatial coordinates, intermediate spatial coordinates and ending spatial coordinates of each curve segment are extracted to obtain the starting point coordinates, intermediate point coordinates and ending point coordinates of the curve segment.

[0043] Based on the coordinates of the starting point, intermediate point, and ending point of the curve segment, a specific value reflecting the curvature of the curve segment is derived through spatial coordinate calculation. This value is used as the characteristic index of the curve segment corresponding to the cable to be laid. By summarizing the characteristic index of all curve segments, the bending radius parameter of the cable to be laid is obtained.

[0044] The bending radius parameter is generated by the coordinate vectors of the starting point, the intermediate point, and the ending point. The coordinate vectors of the starting point, the intermediate point, and the ending point are all collected from the actual points along the secondary cable laying path of the substation. The magnitude of the vector is obtained by taking the square root of the sum of the squares of the components of the coordinate vector. The cross product of the vectors is obtained by taking the difference after cross-multiplying the corresponding components of the two coordinate vectors and then taking the magnitude.

[0045] The bending radius parameter is used to quantify the degree of bending of the arc segment formed by the starting point, intermediate point and ending point on the secondary cable laying path of the substation. It directly reflects the bending state of the cable on this segment of the path and provides a quantitative basis for the compliance verification of cable laying.

[0046] When the starting point, the middle point, and the ending point are collinear, the magnitude of the cross product of the two coordinate vectors approaches zero, and the bending radius parameter approaches infinity. When the area of ​​the triangle formed by the three points increases, the bending radius parameter increases accordingly. When the magnitude of the cross product of the two coordinate vectors increases, the bending radius parameter decreases accordingly.

[0047] The beneficial effects are that by accurately calibrating the endpoints of the channel segments and inserting intermediate points, the three-dimensional spatial location information of the cable is presented in a refined manner, providing a precise spatial basis for cable layout. With the help of neighborhood curvature clustering analysis and curve feature point fitting and merging, the curve segments of the cable path can be accurately identified and key coordinates can be extracted. The bending radius parameter calculated based on these coordinates can quantitatively reflect the spatial morphological constraints of the cable, providing a core quantitative indicator for the feasibility judgment of subsequent cable layout through bends. Overall, the accuracy and comprehensiveness of cable spatial morphology analysis are improved, ensuring the scientific nature of subsequent layout planning.

[0048] The spatial deployment module 104 is used to plan the deployment of the cable to be deployed by using the three-dimensional spatial location information as a deployment reference and combining the cable attributes of the cable to be deployed, so as to obtain the spatial deployment characterization of the cable to be deployed. In this embodiment of the invention, when the spatial deployment module performs deployment planning for the cable to be deployed using the three-dimensional spatial location information as a deployment reference and combining the cable attributes of the cable to be deployed, and obtains the spatial deployment characterization of the cable to be deployed, it is specifically used for: The trajectory points of the cable to be laid are used as the spatial orientation reference for the cable to be laid. The cable properties of the cable to be laid are defined by the cable outer diameter, bending radius multiple, and weight per unit length. Based on the cable properties, the cable to be laid is divided into grids to obtain a grid of possible locations for the cable to be laid. Based on the bending radius multiple, the feasibility of bending through the grid of possible locations is determined to obtain the final location of the cable to be laid. Map the grid coordinates of the final deployment location to a three-dimensional spatial coordinate system to obtain the spatial coordinate points of the channel segment of the cable to be deployed; Connect the spatial coordinate points in directional order to obtain the spatial layout characterization of the cable to be laid.

[0049] The spatial deployment module, based on the cable attributes, performs grid-based subdivision of the cable to be deployed, obtaining a grid of deployable locations for the cable. Specifically, it is used for: Based on the channel identifier in the three-dimensional spatial location information, the boundary coordinates of the cross-sectional profile and the position coordinates of obstacles within the cross-section are obtained from the channel attribute information, and the boundary coordinates and the position coordinates are used as the cross-sectional shape parameters of the cable to be laid. The outer diameter of the cable to be laid is used as the basic unit size for grid division, and the channel section cross-sectional width range and channel section cross-sectional height range of the cable to be laid are determined according to the boundary coordinates. The width range and height range of the channel section are divided at equal intervals to obtain the initial grid of the cable to be laid; The initial grid is used to mark the effective deployment area, thereby obtaining the grid of possible deployment locations for the cable to be deployed.

[0050] The encrypted cable trajectory points obtained by the parameter extraction and calculation module are arranged in an orderly manner according to the extension direction of the cable path. The orderly arranged encrypted cable trajectory points are used as the spatial orientation reference of the cable to be laid, and the overall spatial extension direction and path of the cable are determined by this reference.

[0051] The actual external diameter of the cable to be laid, the bending radius multiple required by the cable specification, and the actual weight per unit length of the cable are statistically analyzed. The three types of values ​​reflecting the characteristics of the cable itself are integrated as cable attributes, providing basic data support for the cable itself in subsequent deployment planning.

[0052] Based on the channel identifier carried in the three-dimensional spatial location information, a precise search is performed on the channel attribute information included in the initial wiring parameters to extract the coordinate information of the cross-sectional contour boundary of the corresponding channel in the spatial coordinate system. At the same time, the coordinate information of all obstacles inside the channel cross-section in the spatial coordinate system is extracted. The boundary coordinates of the cross-sectional contour and the position coordinates of the obstacles inside the cross-section are integrated as the cross-sectional shape parameters of the cable to be laid.

[0053] Using the outer diameter of the cable to be laid as the basic unit size for grid division, and referring to the boundary coordinates in the cross-sectional shape parameters, determine the maximum and minimum value ranges of the cross-section of the corresponding channel segment of the cable to be laid in the width direction, and at the same time determine the maximum and minimum value ranges of the cross-section of the channel segment in the height direction, so as to obtain the width range and height range of the cross-section of the channel segment of the cable to be laid.

[0054] Based on the basic unit size corresponding to the cable outer diameter, the cross-sectional width range of the channel section to be laid is divided into equal-spaced transverse sections. At the same time, the cross-sectional height range of the channel section to be laid is divided into equal-spaced longitudinal sections using the same basic unit size. The grid cells formed after the transverse and longitudinal divisions together constitute the initial grid of the cable to be laid.

[0055] By comparing the position coordinates of obstacles within the cross-section with the cross-sectional shape parameters, the grid cells in the initial grid that coincide with the position coordinates of the obstacles are marked as invalid deployment areas, and the grid cells in the initial grid that do not coincide with the obstacles but are within the coordinate range of the cross-sectional outline boundary are marked as valid deployment areas. This completes the calibration of the valid deployment areas of the initial grid and yields the deployable position grid for the cable to be laid.

[0056] Referring to the bending radius multiple in the cable properties, calculate the minimum bending space required for the cable to be laid at the bending position. Compare this minimum bending space with the space dimensions of each grid cell in the bending area of ​​the available laying position grid. Grid cells that cannot meet the minimum bending space requirement are eliminated, while grid cells that meet the bending space requirement are retained. At the same time, the load-bearing adaptability of the grid cells is considered in combination with the weight per unit length of the cable, and finally the final laying position of the cable to be laid is determined.

[0057] Extract the grid coordinates of all grid cells in the final deployment location, and accurately convert each grid coordinate into the corresponding three-dimensional spatial coordinates according to the coordinate transformation rules of the three-dimensional spatial coordinate system. Integrate these transformed three-dimensional spatial coordinates to obtain the spatial coordinate points of the channel segment of the cable to be laid.

[0058] All spatial coordinate points of the channel segments are reordered according to the extension order corresponding to the spatial direction reference of the cable to be laid. The sorted spatial coordinate points of the channel segments are then connected in sequence by straight lines to form a complete spatial layout path diagram of the cable, thus obtaining the spatial layout representation of the cable to be laid.

[0059] The beneficial effects are as follows: using encrypted cable trajectory points as a spatial reference ensures the accuracy of cable layout paths; combining cable properties with layout planning ensures that the planning scheme is highly compatible with the actual characteristics of the cable; grid-based division based on cable outer diameter enables refined utilization of channel cross-sectional space; the feasibility judgment of bending based on bending radius multiples effectively avoids the problem of cable bending not conforming to specifications; and the spatial layout representation formed by coordinate mapping and orderly connection can intuitively and accurately present the three-dimensional layout status of the cable, providing a complete and accurate layout basis for subsequent offline simulation verification. Overall, it improves the scientificity, standardization and accuracy of cable spatial layout planning, ensuring dual compatibility between the layout scheme and channel space and cable characteristics.

[0060] The offline simulation module 105 is used to construct an offline simulation verification scenario for the cable to be laid based on the deployment characteristics. In this embodiment of the invention, when the offline simulation module executes the offline simulation verification scenario of constructing the cable to be deployed based on the deployment characteristics, it is specifically used for: The spatial layout characterization is analyzed to obtain the spatial coordinate point sequence and cable outer diameter of the cable to be laid; The spatial coordinate point sequence is concatenated to obtain the linear geometric object of the cable to be laid; Using the linear geometric object as the axis, the outer diameter of the cable to be laid is extended radially in space to obtain a virtual entity of the cable to be laid; Based on the cross-sectional profile and direction of the cable to be laid, a hollow tubular virtual channel for the cable to be laid is generated, and the virtual entity is nested inside the hollow tubular virtual channel. The nested virtual entities are spatially associated with the hollow tubular virtual channel to obtain an offline simulation verification scenario for the cable to be laid.

[0061] All spatial coordinate points contained in the spatial deployment representation are extracted and organized in the order of cable routing to form an ordered sequence of spatial coordinate points of the cable to be deployed. At the same time, the outer diameter value of the cable to be deployed is retrieved from the cable attributes to complete the feature analysis of the spatial deployment representation.

[0062] According to the sequential arrangement of the coordinate points in the spatial coordinate point sequence, all coordinate points are connected in series by spatial lines to form a continuous line that can completely reflect the spatial direction of the cable to be laid, thus obtaining the linear geometric object of the cable to be laid.

[0063] Using a linear geometric object as the central axis of spatial extension, and taking half the outer diameter of the cable as the radial extension distance, the spatial radial extension is carried out equally along each spatial direction of the central axis. The closed spatial entity formed by the extension is the virtual entity of the cable to be laid.

[0064] The cross-sectional profile parameters and orientation parameters of the corresponding channel for the cable to be laid are retrieved from the channel attribute information. A hollow tubular structure consistent with the actual channel cross-section is constructed based on the cross-sectional profile parameters. The spatial orientation of the hollow tubular structure is then adjusted according to the orientation parameters to generate a hollow tubular virtual channel for the cable to be laid that matches the actual channel. The virtual entity is placed inside the hollow tubular virtual channel to ensure that the spatial orientation of the virtual entity is completely consistent with the spatial orientation of the hollow tubular virtual channel, thus realizing the nesting of the virtual entity inside the hollow tubular virtual channel.

[0065] The spatial location information of the nested virtual entities and the hollow tubular virtual channels is bound together to establish a spatial relationship between the two. The specific spatial location and relative arrangement of the virtual entities within the hollow tubular virtual channels are clarified. By integrating the bound virtual entities, the hollow tubular virtual channels, and their spatial relationship, an offline simulation verification scenario for the cable to be laid is obtained.

[0066] The beneficial effects are that the core spatial data of cable layout can be accurately extracted by analyzing the characteristics of spatial layout, providing a precise basis for the construction of simulation scenarios. The radial extension with linear geometric objects as the axis can realistically restore the actual spatial shape of the cable. The hollow tubular virtual channel generated by matching the actual channel makes the simulation scenario highly consistent with the actual working conditions of the substation. The nesting and spatial association of virtual entities and virtual channels can construct an offline simulation verification scenario that can completely restore the cable layout state, providing a realistic and accurate virtual verification environment for subsequent interference detection, and ensuring the reliability and accuracy of the interference detection results.

[0067] The interference detection module 106 is used to perform peripheral interference checks on the cable to be laid based on the offline simulation verification scenario, and obtain the interference verification characterization of the cable to be laid. In this embodiment of the invention, when the interference detection module performs a peripheral interference check on the cable to be deployed based on the offline simulation verification scenario to obtain the interference verification characterization of the cable to be deployed, it is specifically used for: An indexing rule is constructed for the offline simulation verification scenario to obtain the spatial index structure of the offline simulation verification scenario; Based on the spatial index structure, a spatial domain range search is performed on the virtual entity of the cable to be laid to obtain the spatial domain of the cable to be inspected. Based on the spatial domain of the cable to be inspected, the offline simulation verification scenario is filtered to obtain candidate interference objects for the cable to be laid. Spatial contour analysis is performed on the candidate interference object to obtain the spatial coordinate boundary of the candidate interference object; The spatial intersection of the spatial coordinate boundary with the spatial boundary coordinate of the spatial domain of the cable to be inspected is compared to obtain the comparison characterization of the cable to be laid. If the comparison indicates the existence of an intersection, then the boundary coordinates and intersection volume of the intersection region are extracted, and the boundary coordinates and intersection volume are used as the interference position and interference amount of the cable to be laid. The interference position and interference amount are correlated and recorded to obtain the interference verification characterization of the cable to be laid.

[0068] Based on the three-dimensional spatial distribution characteristics of virtual entities and hollow tubular virtual channels in offline simulation verification scenarios, retrieval rules are set according to spatial coordinate intervals. At the same time, corresponding association rules between spatial objects and coordinate intervals are established. The two types of rules are integrated into standardized index rules. Based on these index rules, a spatial index structure for offline simulation verification scenarios that can achieve rapid spatial retrieval is built.

[0069] Retrieve all spatial coordinate intervals associated with the virtual entities of the cable to be laid in the spatial index structure, delineate the entire range occupied by the virtual entities in the three-dimensional space according to the coordinate intervals, and accurately define and describe the three-dimensional space range to obtain the spatial domain of the cable to be inspected.

[0070] Based on the three-dimensional spatial coordinate range of the spatial domain of the cable to be inspected, a full-range domain screening is performed in the offline simulation verification scenario to extract all spatial objects whose spatial range may contact or overlap with the spatial domain of the cable to be inspected. All these spatial objects are then summarized to obtain candidate interference objects for the cable to be laid.

[0071] The three-dimensional spatial shape of each candidate interference object is analyzed in all dimensions, and the maximum and minimum coordinate values ​​of each candidate interference object in each direction in three-dimensional space are accurately extracted. These coordinate values ​​are used to define the spatial contour range of the candidate interference object and obtain the spatial coordinate boundary of the candidate interference object.

[0072] The spatial boundary coordinates of the spatial domain of the cable under inspection and the spatial coordinate boundary of the candidate interference object are extracted respectively. The coordinate intervals of the two sets of coordinates in the three directions of X-axis, Y-axis and Z-axis in three-dimensional space are compared one by one to determine whether there is any overlap between the two sets of coordinate intervals. Based on the judgment result, the corresponding judgment result information is formed to obtain the comparison characterization of the cable to be laid.

[0073] When the comparison and characterization show that there is an intersection between the spatial coordinate boundary of the cable under inspection and the spatial coordinate boundary of the candidate interference object, all boundary coordinates of the intersection part in three-dimensional space are accurately extracted. At the same time, the actual volume of the intersection part is calculated according to the three-dimensional space volume calculation rules. The extracted boundary coordinates of the intersection area are used as the interference position of the cable to be laid, and the calculated intersection volume is used as the interference amount of the cable to be laid.

[0074] For each interference location, a corresponding interference quantity is matched. The interference location and the interference quantity are associated one by one using a key-value pair storage format. At the same time, the cable channel segment and candidate interference object type corresponding to the interference location are recorded. The information of all associated records is integrated and summarized to obtain the interference verification characterization of the cable to be laid.

[0075] The beneficial effects are as follows: by constructing a spatial index structure, the spatial domain of the cable under inspection is quickly and accurately retrieved, which greatly improves the efficiency of interferometry detection. The domain screening based on the spatial domain range can comprehensively extract candidate interference objects, avoiding the omission of interference objects. The precise determination of spatial intersection is achieved by comparing the three-dimensional coordinates one by one. The extraction of the boundary coordinates and volume of the intersection area can quantitatively reflect the interference state. Finally, the association record makes the interference verification characterization have clear correlation and traceability, providing accurate and comprehensive interference data support for subsequent review and optimization, and ensuring the accuracy and completeness of the interference detection results.

[0076] The verification and optimization module 107 is used to verify and adjust the path topology based on the interference verification characterization to obtain an interference-free cabling scheme for the cable to be laid.

[0077] In this embodiment of the invention, when the verification and optimization module performs verification and adjustment of the path topology based on the interference verification characterization to obtain an interference-free cabling scheme for the cable to be laid, it is specifically used for: Multi-dimensional feature analysis is performed on the interferometric verification characterization to obtain the interference position identifier, interference type identifier, and interference boundary data of the interferometric verification characterization; Based on the interference position identifier, the node location of the path topology is performed to obtain the path nodes to be verified for the cable to be laid, and the node occupancy status data and adjacent channel reserve data of the path nodes to be verified are extracted. Based on the interference type identifier and the node occupancy status data, the conflict type of the path node to be reviewed is determined to obtain the path adjustment constraint data of the cable to be laid. Based on the path adjustment constraint data, the adjacent channel surplus data is matched for compliance to obtain the alternative detour channel data of the cable to be laid, and the channel occupancy data in the path node to be reviewed is replaced with the alternative detour channel data to obtain the optimized local path topology data of the cable to be laid. The optimized local path topology data is logically concatenated with the unadjusted portion of the path topology relationship to obtain an interference-free cabling scheme for the cable to be laid.

[0078] All related information stored in the interferometric verification characterization is comprehensively and multidimensionally decomposed and analyzed to accurately extract specific information for identifying the specific location of the interference, specific identifiers for distinguishing specific types of interference, and relevant data that can reflect the spatial boundary of the interference region. Thus, the interference location identifier, interference type identifier, and interference boundary data of the interferometric verification characterization are obtained respectively.

[0079] The interference location markers are matched one by one with the node markers of each channel segment in the path topology. Based on the matching results, the path node corresponding to the interference location is accurately located in the path topology, and the path node to be verified for the cable to be laid is obtained. At the same time, the current channel resource occupancy data of the path node to be verified and the remaining usable space data of all adjacent channels of the node are retrieved from the preset channel data repository and extracted as node occupancy status data and adjacent channel reserve data of the path node to be verified.

[0080] By combining the specific type of interference reflected by the interference type identifier and the resource occupancy status of the path node to be reviewed presented by the node occupancy status data, the spatial conflict type of the path node to be reviewed is accurately determined according to the preset conflict determination rules. Based on the determination results, the relevant constraints such as spatial range, channel type, and deployment specifications that the path node needs to follow when making path adjustments are clarified, and the path adjustment constraint data of the cable to be deployed is obtained.

[0081] Using path adjustment constraint data as the core judgment basis, a comprehensive compliance verification and matching is performed on the remaining space, connectivity, and deployment specification adaptability of all adjacent channels in the adjacent channel surplus data. Adjacent channels that fully meet the path adjustment constraint requirements and have usable conditions are selected. The identification information, spatial parameters, connectivity relationships, etc. of these channels are integrated to obtain the alternative detour channel data of the cable to be laid. Then, the original channel occupancy data of the path nodes to be reviewed in the path topology relationship is replaced with the alternative detour channel data to complete the adjustment and optimization of local path nodes and obtain the optimized local path topology data of the cable to be laid.

[0082] The optimized local path topology data is seamlessly logically spliced ​​with the original path topology data that has not interfered with or been adjusted, according to the path connectivity order and connection relationship. This ensures that the spliced ​​path topology relationship remains complete and standardized in terms of spatial connectivity and node connection, and integrates to form a completely new cable path topology relationship without spatial interference, resulting in an interference-free cabling solution for the cable to be laid.

[0083] The beneficial effects are as follows: by analyzing the multi-dimensional features of the interference verification characterization, the core interference data required for review and optimization can be accurately extracted, providing a clear direction for path adjustment. The node positioning based on the interference position identifier enables the accurate locking of the problem path, avoiding the efficiency loss caused by indiscriminate review. Combining the conflict judgment of interference type and node occupancy status makes the path adjustment constraints more targeted and ensures the rationality of the adjustment direction. The alternative detour channels screened by compliance matching can effectively solve the spatial interference problem. The method of local optimization and overall splicing retains the original reasonable path while solving the interference. The final interference-free cabling scheme not only ensures the spatial compliance of cable laying, but also takes into account the scientificity and integrity of the path, greatly improving the practicality and reliability of the cable laying scheme.
