Description

Technical Field

[0002] Against the backdrop of an accelerating global energy transition, hydropower, as a key component of clean, renewable energy, is experiencing a new peak in its development and construction. Hydropower station construction projects are large-scale and technically complex, and cable laying, as a critical link in power transmission, plays a decisive role in the safe and stable operation of the entire hydropower station.

[0003] In the past, cable routing was manually drawn during the planning phase of cable laying, making it difficult to fully consider electromagnetic interference between cables, spatial avoidance, and future equipment expansion requirements. During construction, the lack of real-time monitoring prevented timely detection of issues such as excessive cable tension and substandard bend radii. These potential risks could easily lead to cable failures during later operation.

[0004] To meet the requirements of intelligent and refined management of the entire process of hydropower station project design, construction, operation and maintenance, and to improve the efficiency and quality of hydropower station construction, existing technologies propose to lay cables through 3D simulation. However, since current 3D software is not specifically designed for cable laying in hydropower stations, it is difficult to accurately and quickly complete cable path planning when faced with massive cable laying scenarios such as hydropower stations. Summary of the Invention

[0056] The embodiments of the present invention provide a cable laying method, device and system for solving the technical problem that it is difficult to accurately and quickly complete cable path planning when faced with massive cable laying scenarios such as hydropower stations because current three-dimensional software is not specifically used for cable laying in hydropower stations.

[0057] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0058] See also Figure 1 , Figure 1 A flowchart of the steps of a cable laying method provided in an embodiment of the present invention.

[0059] The present invention provides a cable laying method, comprising:

[0060] Step 101: upon receiving a construction facility drawing and a rule selection instruction, cable routing is planned on the construction facility drawing according to the constraints specified in the rule selection instruction to obtain an initial cable routing plan;

[0061] Construction facility drawings refer to engineering drawings that record the structures of facilities to be constructed. In this embodiment, they refer to engineering drawings for hydropower stations, etc., where a large number of cables are laid, the equipment power is high, and the cable types need to be strictly separated to avoid signal misoperation.

[0062] Rule selection instructions refer to instructions generated in response to user trigger actions on the visual operation layer, which are used to specify constraint conditions.

[0063] In this embodiment, by receiving the construction facility drawings uploaded by the construction unit, the drawings contain detailed information such as the building structure and equipment location. At the same time, the rule selection instructions input by the operator through the human-computer interaction interface are received to clarify the constraints that need to be followed in this cable path planning. The construction facility drawings are processed using image recognition technology and spatial analysis algorithms. The position, direction, size, and distribution of other obstacles of the bridge are identified. According to the constraints in the rule selection instructions, such as the minimum bending radius limit of the cable, the radius of the cable turning point is ensured to meet the requirements when planning the bridge path; according to the load-bearing capacity of the bridge, the positions of cables of different quantities and specifications on the bridge are reasonably allocated. Through the path search algorithm, the initial laying path of the cable is generated to form an initial laying plan.

[0064] Among them, the constraints include parallel and priority sorting. Parallel means that all constraints must be met at the same time during the cable path planning process. Priority sorting means that at least one constraint can be met in descending order of priority. For example, the priority from high to low is: fewer turns > same model and specification go on one floor > cables go on the lower bridge first. You can choose whether to use "same model and specification go on one floor" and "cables go on the lower bridge first" in the constraints and adjust the priority order.

[0065] In one example of the present invention, step 101 may include the following sub-steps:

[0066] When receiving the construction facility drawings and rule selection instructions, select the corresponding constraint conditions according to the rule selection instructions;

[0067] Parse the construction facility drawings to obtain multiple layers of planned facilities;

[0068] The cable path is planned for each layer of facilities to be planned according to the constraints, and the initial laying plan is obtained respectively.

[0069] In this embodiment, upon receiving construction facility drawings and rule selection instructions input by the operator via the visual operation layer, corresponding constraints are selected from a pre-set rule library in accordance with the rule selection instructions. These constraints may include, but are not limited to, cable physical properties (such as minimum bend radius, maximum allowable tensile force, etc.), construction safety regulations (such as safe distances from flammable and explosive areas, etc.), electrical performance requirements (such as spacing requirements for cables of different voltage levels), and spatial limitations of construction facilities (such as cable tray size and available space, etc.).

[0070] To facilitate the subsequent presentation of the cable laying plan in a 3D model, construction facility drawings can be parsed using image recognition and data analysis to identify planned facilities at different levels within the drawings. This includes, but is not limited to, building floor structures, electrical equipment distribution, and the routing of cable bridges and pipelines. For example, cable laying at a hydropower station typically involves complex, multi-layered structures, with a massive amount of cable laying required for each level of planned facilities. After parsing the construction facility drawings, edge detection and feature extraction techniques are used to identify various elements within the drawings, such as building walls, doors and windows, the outlines of electrical equipment, and the shape and location of cable bridges and pipelines. Using 3D modeling techniques, a 3D model of the construction facility is constructed based on the identified elements. During the modeling process, the facilities at different levels are layered to accurately define the spatial scope and structural characteristics of each level. Furthermore, each facility element is assigned corresponding attribute information, such as material, size, and load-bearing capacity. The constructed three-dimensional model and related attribute information are further organized and analyzed to extract key information related to cable path planning, such as the available space of facilities on each floor and the distribution of obstacles.

[0071] After obtaining the constraints and relevant information about the planned facilities, an intelligent path planning algorithm is used to plan the cable paths for each floor of the planned facilities, based on the selected constraints. During the planning process, the starting and ending points of each cable type, the spatial layout of the facilities on each floor, and the constraints are comprehensively considered to determine the optimal routing path for each cable type within each floor, and an initial routing plan is generated for each floor. The starting point is typically the location of the power supply equipment or distribution box, and the ending point is the location of the electrical equipment. Based on the selected constraints, the cable routing path is restricted and optimized. For example, if the constraints specify a minimum bending radius for the cable, the path planning ensures that the radius of all turns meets this requirement. If there are safety distance requirements from flammable and explosive areas, these areas are avoided by a certain distance during path planning.

[0072] Optionally, the constraint condition includes at least one of the following:

[0073] When the difference in the planned cable lengths is less than the preset gap threshold, the planned path with the least number of turns is selected;

[0074] When the planned cable length difference is less than the preset gap threshold, the planned path of the lower bridge is selected;

[0075] When the difference in the planned cable lengths is less than the preset gap threshold, the planned path with existing cables of the same model and specifications is selected;

[0076] When the detour length of the planned path exceeds the preset detour threshold and the excess capacity percentage has not reached the maximum value, a planned path that can exceed the capacity is selected;

[0077] When there are necessary points, connect each necessary point in sequence.

[0078] The cable planning length difference refers to the length difference between the two planned paths generated by using the path planning algorithm to plan the path of a certain cable.

[0079] In this embodiment, the constraint conditions are used to constrain the planned path selected during the path planning process. After the user selects at least one constraint condition through the rule selection instruction, the cable path planning is performed for each layer of the planned facilities. Specifically, during the cable path planning process, if the difference in the planned cable lengths is less than the preset difference threshold, the planned path with the least number of turns can be selected, and / or the planned path of the lower bridge can be selected, and / or the planned path where cables of the same model and specification already exist can be selected. This solves the problem of cable skipping, and at the same time, long cables are preferentially laid in the lower layer of the bridge. The first cable passing through the bridge determines the model and specification of the cables that are preferentially passed through in the current bridge; the weight is the length of the cables with the same model and specification in the path.

[0080] Furthermore, when cable routing involves detours, rule selection commands can be used to configure detour thresholds and over-capacity percentages. To determine whether a detour exists, the shortest path length is compared with the cable's length. If the acceptable length does not exceed the set value, the acceptable path is selected. If the over-capacity length does not exceed the set value, the over-capacity path is selected. Otherwise, the acceptable path is selected. If the acceptable path is unavailable, the over-capacity path is selected. If the over-capacity path also fails, the cable is considered unavailable.

[0081] For the necessary points during cable laying, the user can enter them sequentially when defining the constraints. When planning the cable path, each necessary point is checked to see if it affects the connectivity of the current node, the subsequent necessary points, and the destination. Connectivity means that there is a path from the current node to the subsequent necessary node 1; there is a path from the subsequent necessary node 1 to the subsequent necessary node 2; ... there is a path from the subsequent necessary node n to the destination, such as Figure 2 shown.

[0082] Step 102: rearrange the cables in the common path in the initial laying plan according to the cable attributes to obtain an intermediate laying plan;

[0083] In this embodiment of the present invention, cable routing is a holistic process, targeting each floor of planned facilities. Therefore, connections between facilities on each floor, such as vertical bridges, may conflict with each other, or interfere with the routing of cables in the common path. Therefore, it is necessary to further rearrange the cables in the common path to reduce the impact between signal cables and power cables. Specifically, information about the cables in the common path from the initial routing plan is extracted, including attributes such as each cable's voltage level, purpose, outer diameter, and quantity. Classification is performed based on the cable attributes, with high-voltage power cables grouped in one category and low-voltage control cables in another. Based on the classification results, the cables in the common path are rearranged. For example, high-voltage cables are placed on the upper or outer sides of the bridge to reduce electromagnetic interference with other cables. Cables with larger outer diameters are preferentially placed in locations with ample bridge space to ensure a compact and reasonable cable arrangement, resulting in an intermediate routing plan.

[0084] In one example of the present invention, step 102 may include the following sub-steps S11-S12:

[0085] S11. Comparing the priorities of the cables in the common path in the initial laying plan according to the cable attributes to obtain the cable priority of each cable in the common path;

[0086] Furthermore, the cable attributes include the number of cables, the cable voltage level, and the cable usage type; S11 may include the following sub-steps:

[0087] The cables in the common path in the initial laying plan are divided according to the cable usage type to obtain multiple groups of intermediate cables;

[0088] Sort the intermediate cables in each group from most to least according to the number of cables to obtain the initial cable priority;

[0089] The initial cable priorities are adjusted from high to low according to the cable voltage levels to obtain the cable priority of each cable in the public path.

[0090] In an embodiment of the present invention, in a cable laying project, information on all cables in a common path in the initial laying plan is obtained, including detailed parameters such as the cable model, specification, and purpose. Intermediate cables are divided according to the type of cable use. Each group of intermediate cables is sorted in order from the largest to the smallest number of cables. Using a sorting algorithm (such as bubble sort, quick sort, etc.), the group with the largest number of cables is placed in front, and the group with the smallest number is placed in the back, thereby obtaining an initial cable priority order. Based on the initial cable priority, each priority is adjusted from high to low according to the voltage level. For cables in the same priority group, if there is a difference in voltage level, the priority of the cable with the higher voltage level is further increased.

[0091] For example, cables marked as "power" are grouped as power cables, cables marked as "control" are grouped as control cables, cables marked as "communication" are grouped as communication cables, and so on. If the power cable group is the largest, followed by the control cable group, and the communication cable group is the smallest, the initial priority order is power cable group > control cable group > communication cable group. Within the power cable group, if there are cables of both 10kV and 380V voltage levels, the 10kV power cable is prioritized over the 380V power cable. Through such adjustments, the precise cable priority of each cable within the common path is ultimately determined, providing a scientific basis for subsequent cable laying and arrangement.

[0092] like Figure 3 As shown, in this embodiment, the cables in the common path are compared pairwise. If there are multiple common paths, the comparison process is divided into multiple segments to consider the cable priority.

[0093] S12. Rearrange the cables in the public path according to their priorities from high to low to obtain an intermediate laying plan.

[0094] After determining the cable priority for each cable group, rearrange the cables within the common path. During the rearrangement process, prioritize the placement of high-priority cables, taking into account factors such as cable bend radius and spacing requirements to ensure a tight and reasonable cable arrangement. High-priority cables are placed on the upper levels of the bridge or near equipment to minimize crosstalk and interference with other cables, resulting in a central routing solution.

[0095] Taking the above cable priority as an example, the high-priority 10kV power cable can be laid first. Based on the structure of the bridge, it can be placed on the upper layer of the bridge and as close to the equipment end as possible to reduce the number of crossings and bends with other cables. During the laying process, use clamps to secure the cables to ensure that they meet the bending radius requirements and maintain a certain spacing. Next, lay the 380V power cable and place it in a suitable position below the 10kV power cable. Then lay the control cables and communication cables in sequence, arranging them reasonably according to their priority and actual conditions. During the arrangement process, pay attention to avoid electromagnetic interference between different types of cables. For example, maintain a certain safe distance between communication cables and power cables to obtain an intermediate laying plan.

[0096] Step 103: If there is a laying conflict in the intermediate laying plan, the intermediate laying plan is updated according to a preset optimization rule to obtain a target cable laying plan.

[0097] After the generation of the intermediate laying plan is completed, although the cables in the common path have been rearranged, there may be laying conflicts such as crossing and overlapping between different levels. For this reason, the intermediate laying plan can be further comprehensively checked, and computer simulation technology can be used to check whether there is any crossing or overlapping between the cables, and whether the distance between the cables and the edge of the bridge and other equipment meets safety regulations. If a laying conflict is found, the preset optimization rules are activated. For example, for two crossed cables, their priority is determined. If one is a low-priority control cable and the other is a high-priority power cable, the path of the low-priority control cable is adjusted first. When adjusting the path, check again whether the rule constraints are met, such as whether it exceeds the range of the bridge and whether the minimum bending radius requirements are violated. After multiple adjustments and optimizations, until all laying conflicts are eliminated, the final target cable laying plan is obtained.

[0098] In one example of the present invention, step 103 may include the following sub-steps:

[0099] If there is a laying conflict in the middle laying plan, and the location of the laying conflict is the vertical bridge, determine whether the opening direction of the vertical bridge is consistent with the opening direction of the horizontal bridge connected at both ends;

[0100] If the opening direction of only one end is inconsistent, reverse the horizontal bridge;

[0101] If the opening directions at both ends are inconsistent, reverse the vertical bridge;

[0102] If there is a routing conflict in the middle routing scheme, and the routing conflict occurs at the horizontal bridge, the cable priority at both ends of the horizontal bridge is determined;

[0103] Set the cable crossover point at the weakest end of the cable priority;

[0104] When all laying conflicts are eliminated, the intermediate laying plan at the current moment is determined as the target cable laying plan.

[0105] In an embodiment of the present invention, after the generation of the intermediate laying plan is completed, there may still be some laying conflicts caused by the facility structure, in order to minimize the adverse effects of cable crossing and overlapping. At this time, the intermediate laying plan can be further tested for laying conflicts to determine the specific locations of crossing and overlapping. If it is detected that there is a laying conflict in the intermediate laying plan, and the location of the laying conflict is the vertical bridge, it is further determined whether the opening direction of the vertical bridge is consistent with the opening direction of the horizontal bridge connected at both ends. If there is an inconsistency in the opening direction of a single end, the horizontal bridge is reversed, and its connection position is determined as the reversal point, such as Figure 4 Inversion point 3. If the opening directions of the vertical bridge and the horizontal bridge connected at both ends are inconsistent, in order to reduce resource consumption, the vertical bridge is reversed at this time, and the connection positions at both ends are the reversal points, such as Figure 4 If the opening directions are consistent, the current positions of the vertical and horizontal bridges are maintained.

[0106] In addition, if the horizontal bridge extends to the vertical bridge, that is, the left and right sides of the horizontal bridge remain unchanged and extend to the vertical bridge, if the opening direction of the horizontal bridge is consistent with the opening direction of the vertical bridge itself, the horizontal bridge does not need to be reversed in the forward and reverse directions; otherwise, it needs to be reversed, and the joint is the reversal point.

[0107] In another example of the present invention, if there is a laying conflict in the intermediate laying plan, and the location of the laying conflict is the horizontal bridge, a priority conflict may occur, that is, Figure 5 As shown, the left side has a strong priority relationship, and the right side has a weak priority relationship. The reasons may include but are not limited to the narrow space and complex turns of the left bridge, which requires priority to ensure the passage of important cables and give them a strong priority; the right side has ample space and simple laying, so the cable priority is relatively weak; or the left side is connected to core production equipment and the right side is connected to ordinary lighting equipment. The left cable has a higher priority because the associated equipment is more critical. The cable priority of various cables at both ends of the horizontal bridge can be located. To avoid cable crossing at the bridge, the cable intersection can be set at the end with the weakest cable priority, such as Figure 6 When all laying conflicts are eliminated, the intermediate laying plan at the current moment is determined as the target cable laying plan.

[0108] Furthermore, the method further comprises:

[0109] If the location of the laying conflict is a horizontal bridge and the first user's check information is received, the intersection point of the cables is set at the end with the strongest cable priority to obtain a new middle laying plan.

[0110] In this embodiment, the first user selected information that crossover is allowed at the four-way connector. After receiving the user's selection of this option, the crossover point of the cable can be set at the end with the strongest cable priority, such as Figure 7 shown.

[0111] In addition, it also includes the second user check information, specifically the priority crossing at the upper and lower bridges. When the user checks this option, regardless of whether the first user check information exists, the two cables will cross at the right position, such as Figure 6 shown.

[0112] In one example of the present invention, the method further includes:

[0113] When there is no routing conflict in the intermediate cable routing plan, the intermediate cable routing plan is determined as the target cable routing plan.

[0114] In this embodiment, if there is no laying conflict in the intermediate laying plan, it indicates that there is no unclear priority relationship in the intermediate cable laying plan at this time, and the plan can be directly determined as the target cable laying plan for output.

[0115] In addition, in order to improve the visualization convenience of the cable laying process in this embodiment, a split-screen display can be performed on the PC side, with one part of the screen outputting a two-dimensional drawing of the cable laying process, and the other part of the screen displaying a three-dimensional model that is updated in real time based on the two-dimensional drawing.

[0116] In an embodiment of the present invention, upon receiving a construction facility drawing and a rule selection instruction, cable routing is performed on the construction facility drawing according to the constraints specified in the rule selection instruction to obtain an initial cable routing plan. Cables in the initial routing plan that are on a common path are rearranged according to their attributes to obtain an intermediate routing plan. If routing conflicts exist within the intermediate routing plan, the intermediate routing plan is updated according to preset optimization rules to obtain a target cable routing plan. Thus, by accurately selecting constraints, thoroughly analyzing the construction facility drawings, and scientifically planning cable routing, an initial cable routing plan that better meets actual construction needs can be generated, effectively avoiding routing conflicts and unreasonable layouts, and effectively improving the safety and stability of subsequent cable routing.

[0152] like Figure 9 As shown, this embodiment provides a cable laying system, which includes a visual operation layer of communication connection, a business layer, an application support layer and an infrastructure layer, wherein a cable laying device is built into the business layer.

[0153] It should be noted that the infrastructure layer is used to build the hardware and software foundation for system operation and is key to ensuring stable system operation. This layer encompasses hardware such as servers and storage devices, as well as software such as operating systems, middleware, and databases, including the basic network environment. Relying on professional data storage technology and architecture, the system efficiently stores and rapidly retrieves the massive and complex data involved in the cable laying process, such as cable model specifications, routing, laying parameters, and operation and maintenance records. Furthermore, it utilizes multiple encryption methods and backup and recovery capabilities to comprehensively ensure data security and integrity, providing a solid foundation for the system to access accurate data at any time.

[0154] The application support layer serves as the "intelligent hub" that maintains the operation of the system, closely connecting the upper-level applications and the underlying infrastructure. On the one hand, in order to meet the upper-level service requirements such as complex cable laying planning, simulation, and operation and maintenance management, it is equipped with a powerful computing engine that can process various algorithms at lightning speed, accurately solve the optimal path, reasonably layout cable arrangements and other difficult problems. On the other hand, it integrates various advanced technical components, such as graphics rendering components to help realistically display three-dimensional models, physical simulation components to simulate the mechanical properties of cables, and then cooperates with smooth process processing modules to standardize the full-process business logic from design to construction and operation and maintenance. At the same time, it opens rich and stable interface services, seamlessly connects to external design software, monitoring equipment, etc., and fully empowers the system to have powerful and flexible application capabilities. It includes but is not limited to the following services or interfaces:

Furthermore, data backup and recovery mechanisms ensure data security and integrity, providing reliable data support for subsequent operation and maintenance and data analysis.

[0165] Digital Planning Module (F03-F06): Leveraging advanced 3D modeling software, a realistic 3D model of the cable laying process is constructed based on the hydropower station's detailed design drawings, equipment layout, and actual on-site topography. Within the model, construction personnel can intuitively visualize the cable laying path, direction, and spatial relationship with surrounding equipment. By simulating different laying schemes and integrating them with construction process requirements and equipment connection needs, the cable laying plan is optimized. For example, the cable path can be adjusted within the model to avoid collisions with other equipment or pipelines, and the cable arrangement can be optimized to improve the spatial utilization of the cable channel. This system allows construction personnel to experience the cable laying process, proactively identify and resolve potential issues, and ensure the feasibility and rationality of the construction plan. The cable laying device in this embodiment of the present invention can implement its cable laying function based on the functionality of this digital planning module.

[0166] Construction Process Monitoring Module (F07-F08): The system receives construction data uploaded by the data acquisition layer in real time and displays it intuitively on the interface. Construction managers can view the real-time progress and key parameters of cable laying anytime and anywhere through computer terminals.

[0167] Collaborative Management Module (F01-F08): Builds a collaborative work platform between design, construction, and operations and maintenance departments. The design department can upload the latest design drawings and change information to the platform, which the construction and operations and maintenance departments can access and view in real time. Construction personnel review the design results and conduct secondary cable design based on them. The system pre-plans cable routes and displays the actual spatial location of cables. The operations and maintenance department can also use the platform to obtain key information about the construction process in advance, preparing for subsequent equipment maintenance. This platform enables real-time information sharing and efficient communication between departments, breaking down information barriers between departments and improving collaborative work efficiency.

[0168] It should be noted that the functions of F01 to F08 are described as follows:

Unified data standards and information exchange mechanisms ensure seamless integration and efficient collaboration across all aspects, breaking the barriers of traditional construction models characterized by independent processes and poor information flow. Data analysis technologies are fully utilized to deeply mine and analyze the massive amounts of data generated during the construction process. Valuable information, such as construction quality trends, equipment operating status, and potential risk warnings, is extracted from real-time cable laying data. These analytical results provide a scientific basis for construction decision-making, enabling refined and intelligent construction management. The designed construction management system boasts excellent compatibility and seamless integration with various existing hydropower station management systems, such as equipment management systems, project management systems, and monitoring systems, enabling data sharing and business collaboration.
