Detailed Implementation

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

Therefore, they should not be construed as limitations on the present invention.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, "a plurality of sets" means two or more sets, "a plurality of pieces" means two or more pieces, and "a number" means one or more, unless otherwise explicitly specified.

[0022] Building Information Modeling (BIM) is a platform that integrates building information throughout the entire building lifecycle. The integrated information includes information from various models such as building models, structural models, plumbing models, and HVAC models, and is used to provide data support during the design, construction, and operation and maintenance phases of any building object.

[0023] Specifically, the design of any building involves the design of multiple systems such as water supply and drainage systems and heating and ventilation systems. When designing the electrical system of a building based on a BIM platform, it is necessary to combine the equipment parameters of the equipment that need to be powered in the existing water supply and drainage system, heating and ventilation system, and other systems.

[0024] Currently, the design of electrical systems is usually carried out by professionals who identify and extract the required equipment parameters from multiple systems. However, different systems rely on technicians in this field for design, and the equipment parameters in these systems also rely on manual input by technicians. Due to human subjective factors, there may be data loss or data abnormalities during input, which leads to low accuracy in the power distribution design when professionals design power distribution based on the equipment parameters in the system.

[0025] Furthermore, power distribution design also relies on the subjective judgment of professionals, and requires their personal experience to perform load calculations, phase balancing, circuit optimization, and other tasks based on the equipment parameters entered for each system, resulting in low efficiency in power distribution design.

[0026] At the same time, when professionals are designing power distribution systems, they also need to produce corresponding power distribution system diagrams, i.e., electrical system single-line diagrams. This requires professionals to draw them manually and label the equipment and lines in the power distribution system diagram one by one, which results in a large workload and further reduces the efficiency of power distribution design.

[0027] Furthermore, when the requirements for power distribution design change, it is necessary to rely on professionals to manually update or adjust data such as the number, location, and type of equipment in the power distribution system diagram, which also presents a large workload problem and further reduces the efficiency of power distribution design.

[0028] Based on this, the present invention discloses a power distribution method based on a BIM platform. By obtaining the electrical equipment information of each electrical device in a building object from the BIM platform, including the device location information, at least one power consumption area in the building object is determined. Based on the location information of each device, the installation location of at least one distribution box in the power consumption area is determined. According to the location information of each device, the device pairing relationship between each distribution box and the electrical device is determined. Based on the device pairing relationship and the installation location of the distribution box, a power distribution scheme for the building object is generated. Power is then distributed to the electrical devices based on the power distribution scheme. This method enables the generation of a power distribution scheme for a building object based on the electrical equipment information of the electrical devices in the BIM platform, improving the accuracy and efficiency of power distribution design.

[0029] See Figure 1 , Figure 1 The diagram illustrates a step-by-step flowchart of a power distribution method based on a BIM platform according to an embodiment of the present invention, which may specifically include the following steps: S101, Obtain the electrical equipment information of each electrical device in the building object from the BIM platform.

[0030] The term "building object" can refer to any object requiring power distribution design. Power distribution design refers to the design of power distribution for electrical equipment within the building object, including energy allocation and circuit planning. Electrical equipment can be any device that requires electrical energy, such as air valves and exhaust fans in the HVAC field, or water supply pump sets and drainage pumps in the water supply and drainage field. Equipment information can be information related to the equipment, specifically including equipment location information and equipment load information. Equipment location information indicates the location of the equipment within the building object, while equipment load information indicates the load on the equipment during actual use, including its rated power, load level, and operating conditions.

[0031] When electrical distribution design is required for a building object, the electrical equipment information of each electrical device in the building object can be obtained from the BIM platform.

[0032] In practical applications, when the water supply and drainage system and the heating and ventilation system of a building have been designed, the relevant personnel will enter the design drawings of the water supply and drainage system, the design drawings of the heating and ventilation system, and the equipment parameters related to the electrical equipment in each system into the BIM platform. Thus, when the power distribution design of the building needs to be carried out, the electrical equipment information of each electrical device in the building can be obtained from the BIM platform.

[0033] S102, Identify at least one electrical area within the building object.

[0034] Among them, the electricity-consuming area can be the area in the building that needs to use electricity, that is, the area in the building where there are electrical equipment.

[0035] After obtaining the electrical equipment information of each electrical device in the building object, the building information of the building object can be obtained.

[0036] Specifically, building information can describe the internal structure of a building object, specifically its object model. Building information can include both two-dimensional and three-dimensional structural information. The object module of a building object can be a three-dimensional model built based on its two-dimensional and three-dimensional structural information, and this three-dimensional model can be imported into the BIM platform.

[0037] After obtaining the building information of the building object, multiple planned areas in the building object can be determined from the building information. Based on the equipment location information of the electrical equipment in the building object, the area in the building object where the electrical equipment exists is determined as the power consumption area, thus obtaining at least one power consumption area in the building object.

[0038] S103, based on the location information of each device, determine the installation location of at least one distribution box in the power consumption area.

[0039] The installation location of the electrical box can be the location where the distribution box is installed.

[0040] After identifying at least one power consumption area, the installation location of at least one distribution box in the power consumption area can be determined based on the equipment location information of each electrical device.

[0041] In practical applications, the distance between any location in the power supply area and each electrical device can be determined based on the device location information of each device. For any given location, the sum of the distances between that location and each electrical device can be determined, thus obtaining the sum of the distances between each location and each electrical device. After obtaining the sum of the distances between each location and each electrical device in the power supply area, the sums of the distances between each location and each electrical device can be sorted, and the location with the smallest sum can be selected as the installation location for the electrical box.

[0042] S104, based on the location information of each device, determine the device pairing relationship between each distribution box and the electrical equipment.

[0043] Among them, the equipment pairing relationship can be the pairing relationship between the distribution box and the electrical equipment, that is, the relationship of which electrical equipment the distribution box is used to distribute power to.

[0044] After obtaining the installation location of the electrical box, the power distribution relationship between each electrical device and each electrical device can be determined based on the device location information of each electrical device and the installation location of each electrical distribution box. That is, the relationship of which electrical devices the distribution box is used to distribute power to can be determined, and the device pairing relationship between each distribution box and the electrical device can be obtained.

[0045] In practical applications, for each distribution box, the distance between the distribution box and each electrical device can be determined based on the device location information of each electrical device and the installation location of the distribution box. The distance between the distribution box and the electrical device is then compared with a preset distance threshold. This allows the distribution box to be designated as the device for which it distributes power to electrical devices that are less than the distance threshold, while the distribution box is designated as the device for which it does not need to distribute power to electrical devices that are more than the distance threshold. This establishes the device pairing relationship between the distribution box and each electrical device. Similarly, the power distribution relationship between each distribution box and each electrical device can be obtained.

[0046] As an example, when the distance between any electrical device and any two distribution boxes is less than the distance threshold, for that electrical device, the distance between the electrical device and each distribution box can be compared to determine the distribution box with the shortest distance as the distribution box used to distribute power to that electrical device.

[0047] S105, Based on the equipment pairing relationship and the electrical box installation location, generate a power distribution scheme for the building object, and distribute power to the electrical equipment based on the power distribution scheme.

[0048] The power distribution scheme may include the power distribution path from each electrical device to the distribution box, and the power distribution path may be the path of the line between the distribution box and the electrical device.

[0049] After obtaining the equipment pairing relationship, the power distribution path from each electrical device to the distribution box can be determined based on the equipment pairing relationship and the installation location of the distribution box, thus obtaining the power distribution scheme of the building object. Based on the power distribution scheme, the lines and distribution boxes are laid out, and then the distribution box can distribute power to the electrical devices through the determined power distribution path.

[0050] In one embodiment of the present invention, S105 may include S1051 to S1052: S1051, Determine the wiring area in the building object based on the building information of the building object.

[0051] The wiring area can be any area within the building where wires or cables can be laid.

[0052] After obtaining the equipment pairing relationship, the wiring areas in the internal structure of the building object that can be used to lay wires or cables can be determined based on the building information.

[0053] It is important to understand that the wiring between the distribution box and the electrical equipment is generally made of wires or cables. These wires or cables are usually run in cable trays, which are typically suspended from the ceiling and have a certain installation height. When the wiring encounters internal structures such as structural walls or columns, the cable tray cannot pass through them. Therefore, the area containing the internal structures such as structural walls and columns in the building can be determined as an area where wiring is not allowed. The area outside the internal structures such as structural walls and columns is the area where wires or cables can be laid.

[0054] S1052, based on the wiring area, equipment pairing relationship and electrical box installation location, determine the shortest path from each electrical device to the distribution box as the power distribution path, and generate a power distribution scheme that distributes power to the electrical devices according to the power distribution path.

[0055] After determining the wiring area, the distribution box corresponding to each electrical device can be determined based on the device pairing relationship. That is, the distribution box used to distribute power to the electrical device can be determined. After obtaining the distribution box corresponding to each electrical device, multiple feasible paths between the electrical device and the corresponding distribution box can be determined in the wiring area based on the device location information of each electrical device and the installation location of each distribution box. Then, the shortest path can be determined from the multiple feasible paths as the power distribution path from the electrical device to the distribution box, and a power distribution scheme is generated to lay wires or cables between the electrical device and the corresponding distribution box along this power distribution path. Thus, a power distribution scheme is obtained to lay wires or cables between each electrical device and the distribution box to distribute power to the electrical device.

[0056] In practical applications, the installation locations of electrical equipment and distribution boxes, as well as the area between the electrical equipment and the distribution boxes, can be abstracted into a two-dimensional grid. The electrical equipment is taken as the starting grid, and the installation location of the distribution box is taken as the ending grid. Based on the location of the wiring area, the passable and impassable areas in the two-dimensional grid are determined. Then, the A* heuristic path search algorithm can be used to iteratively calculate the estimated cost value of each grid from the starting grid to the ending grid. The path with the lowest estimated cost value is the shortest path, which is the power distribution path of the electrical equipment.

[0057] As an example, after determining the power distribution path, the type of cable or wire corresponding to the electrical equipment can be selected based on the model of the electrical equipment. For example, when the electrical equipment is a fan with a primary load, the corresponding cable type can be a fire-resistant cable, and when the electrical equipment is a fan with a secondary load, the corresponding cable type can be a flame-retardant cable.

[0058] In one embodiment of the present invention, the method may further include the following steps: Based on the power distribution plan, equipment information, and preset power distribution templates, power distribution design drawings are generated.

[0059] Among them, the power distribution template can be a pre-made, reusable format template based on the drawing requirements of the electrical system, including standardized graphics and parameter sets of various types of electrical equipment and components. The power distribution design drawings can be standardized technical drawings used to guide power distribution construction. The power distribution design drawings can include labeling information of distribution boxes, electrical equipment, and power distribution paths. The labeling information can include the circuit number, identification, model, specifications, etc. of the distribution boxes, electrical equipment, and power distribution paths.

[0060] Specifically, the labeling information for power distribution routes can also include information such as the cable tray number, dimensions, and installation height.

[0061] After obtaining the power distribution plan, a format template corresponding to the electrical equipment can be selected from the preset power distribution templates, and the information of the electrical equipment can be entered into the parameters of the format template. Then, based on the standardized graphics corresponding to the electrical equipment and the set of entered parameters, an initial power distribution design drawing can be generated. According to the power distribution path of each electrical equipment and the distribution box in the power distribution plan, the connection between the electrical equipment and the distribution box can be made in the initial power distribution design drawing to obtain the final power distribution design drawing.

[0062] As an example, the power distribution scheme also includes the type of cable or wire selected for each electrical device, and the type of cable or wire selected can be entered into the parameters of the format template to obtain the parameter set of the format template.

[0063] Specifically, the parameter set of the format template can include a cable list, which can include information about the cable or wire selected for each electrical device, such as cable number, start point, end point, model, specifications, length, etc.

[0064] In one embodiment of the present invention, before generating power distribution design drawings based on the power distribution scheme, electrical equipment information, and a preset power distribution template, the following steps may be included: The power distribution plan is displayed to the user. When the user's modification operation on the power distribution plan is detected, the modification operation is responded to and the power distribution plan is modified to obtain the modified power distribution plan. Based on the modified power distribution plan, the steps of generating power distribution design drawings are performed according to the power distribution plan, electrical equipment information and preset power distribution template.

[0065] The correction operation allows users to modify the power distribution plan, including adjusting electrical equipment, distribution boxes, and power distribution paths.

[0066] After obtaining the power distribution plan, a visual interface can be generated based on the plan and pushed to the relevant users, such as through SMS, mini-program notifications, application information, third-party links, etc., so that the power distribution plan can be displayed to the users.

[0067] When the power distribution plan is presented to the user, the user can modify the power distribution plan according to their needs. The system can detect the modification operation performed by the user in real time. When the modification operation is detected, the system will respond to the modification operation and modify the power distribution plan to obtain the modified power distribution plan. Based on the modified power distribution plan, the system will perform the step of generating power distribution design drawings according to the power distribution plan, electrical equipment information and preset power distribution template.

[0068] In this embodiment of the invention, by obtaining the electrical equipment information of each electrical device in a building object from a BIM platform, including the device location information, at least one electrical area in the building object is determined. Based on the location information of each device, the installation location of at least one distribution box in the electrical area is determined. According to the location information of each device, the device pairing relationship between each distribution box and the electrical device is determined. Based on the device pairing relationship and the installation location of the distribution box, a power distribution scheme for the building object is generated. Power is then distributed to the electrical devices based on the power distribution scheme. This enables the generation of a power distribution scheme for the building object based on the electrical equipment information of the electrical devices in the BIM platform, improving the accuracy and efficiency of power distribution design.

[0069] See Figure 2 , Figure 2 The present invention illustrates a flowchart of another power distribution method based on a BIM platform according to an embodiment of the present invention, which may specifically include the following steps: S201: Obtain the electrical equipment information of each electrical device in the building object from the BIM platform.

[0070] S202, Identify at least one electrical zone within the building object.

[0071] S203, based on the equipment load information, equipment location information and the maximum power distribution load of the distribution box of the electrical equipment in the power consumption area, divide all electrical equipment in the power consumption area into at least one power distribution list.

[0072] The equipment load information can be the electrical load of the electrical equipment. The power distribution list can be represented as an energy allocation list, i.e., a detailed table of how electrical energy is allocated. The power distribution list can include at least one electrical device, and different target locations can correspond to different power distribution lists. The target location can be determined based on the equipment location information of all electrical devices in the power distribution list. The maximum power distribution load can be the maximum load of electrical energy that the distribution box can allocate.

[0073] After determining the power consumption area, for each power consumption area, the equipment load information and equipment location information of each electrical device in the power consumption area can be determined, as well as the maximum power distribution load of the distribution box. Then, based on the equipment load information, equipment location information and maximum power distribution load of the electrical devices in the power consumption area, all electrical devices in the power consumption area can be divided into at least one power distribution list.

[0074] In one embodiment of the present invention, S203 may include S2031 to S2033: S2031, determine the total load information of the power consumption area based on the equipment load information of the electrical equipment in the power consumption area.

[0075] The total load information can be the sum of the electrical loads of all electrical devices in the power consumption area.

[0076] After determining the power consumption area, for each power consumption area, the total power load of each electrical device in that area can be calculated to obtain the total load information of that power consumption area, thus obtaining the total load information of each power consumption area.

[0077] S2032, Based on the total load information and the maximum power distribution load, determine the expected number of distribution boxes in the power consumption area.

[0078] The desired quantity can be the number of distribution boxes required to distribute power to electrical equipment in the power consumption area.

[0079] After obtaining the total load information for each power consumption area, the number of distribution boxes required for each power consumption area can be determined based on the total load information of the power consumption area and the maximum power distribution load of the distribution box, thus obtaining the expected number of distribution boxes for the power consumption area, and thus obtaining the expected number of distribution boxes for each power consumption area.

[0080] For example, the building object includes an electrical area A, and the total load information of electrical area A can be 145kw. The maximum power distribution load of the distribution box can be 50kw. It can be determined that in order to meet the normal operation of all electrical equipment in electrical area A, 145kw of power needs to be allocated to electrical area A. That is, at least 3 distribution boxes need to be equipped for electrical area A to meet the power demand of electrical area A. Thus, the expected number of distribution boxes in electrical area A is 3.

[0081] S2033, based on the expected number of distribution boxes and the equipment load information and equipment location information of the electrical equipment, cluster all electrical equipment in the power consumption area using a preset clustering algorithm to obtain at least one power distribution list.

[0082] The number of power distribution lists can be the same as the expected number of power distribution boxes. Clustering algorithms can be used to cluster power devices based on the distance between them and the sum of their load information.

[0083] Specifically, clustering algorithms can be mean clustering algorithms, such as the K-means clustering algorithm.

[0084] After obtaining the expected number of distribution boxes in each power consumption area, for each power consumption area, the expected number of distribution boxes can be determined as the number of clusters obtained by clustering. Based on the equipment location information, equipment load information and the determined number of clusters for each electrical device, a preset clustering algorithm is used to cluster all electrical devices in the power consumption area to obtain at least one power distribution list.

[0085] The specific clustering process is as follows: Multiple target electrical devices are identified from all electrical devices in the power consumption area, and their location information is used as cluster centers. The number of target electrical devices is the same as the number of sets. Based on the location information of each electrical device, the distance from each device to each cluster center is determined. For each device, the distance between it and each cluster center is obtained, and the device is assigned to the cluster center with the shortest distance, resulting in multiple sets of electrical devices. Based on the load information of each device, the total load of each set of electrical devices is calculated. For any set of electrical devices, if the total load of the set exceeds the maximum distribution load of the distribution box, the device with the longest distance in that set is assigned to another set of electrical devices, until the total load of that set is less than or equal to the maximum distribution load of the distribution box. After obtaining the set of electrical equipment that has been redistributed, the average position of all electrical equipment in each set can be calculated based on the equipment location information of each electrical equipment. This average position is the new cluster center. The above steps are repeated to iteratively calculate the position of the cluster center until the position of the cluster center no longer changes, or the number of iterations reaches a threshold, or the change in the cluster center is less than the threshold. The set of electrical equipment clustered by the final cluster center is used as the power distribution list, resulting in at least one power distribution list.

[0086] S204, Based on the equipment location information of all electrical equipment in the power consumption area, determine at least one target location in the power consumption area.

[0087] The target location can be the optimal location in the power consumption area for installing the distribution box. The optimal location can be represented as the location with the smallest sum of distances to each electrical device in the power consumption area.

[0088] After identifying at least one power consumption area, for each power consumption area, at least one target location can be determined based on the equipment location information of all electrical devices in that power consumption area.

[0089] In practical applications, the geometric center point between all electrical devices in a given electrical area can be calculated based on the device location information of all electrical devices; this is the target location. Specifically, based on the device location information of each electrical device, the three-dimensional coordinates of the device within the building object can be determined, and the average values ​​of the three-dimensional coordinates of each device along the x-axis, y-axis, and z-axis within the building object can be calculated; these average values ​​are then used to determine the geometric center point.

[0090] As an example, all electrical devices in the power consumption area can be divided into multiple sets of electrical devices, and the geometric center point between all electrical devices in each set of electrical devices can be calculated to obtain multiple target locations, that is, each set of electrical devices corresponds to one target location.

[0091] In one embodiment of the present invention, different target locations correspond to different power distribution lists, and the target locations are determined based on the equipment location information of all electrical devices in the power distribution list.

[0092] In practical applications, for each power consumption area, at least one power distribution list can be determined in that power consumption area. Based on the equipment location information of all electrical equipment in each power distribution list, the geometric center point between all electrical equipment in each power distribution list is calculated, which is the target location of each power distribution list, thereby obtaining at least one target location.

[0093] S205 identifies multiple installable areas within an electrical area.

[0094] The installable area can be any area in the power consumption area that can be used to install a distribution box.

[0095] After determining at least one target location, multiple installable areas can be identified within the power supply area.

[0096] In practical applications, since distribution boxes are generally installed on structural walls, it is not recommended to install them on load-bearing walls within the building. Therefore, the areas containing all structural walls other than load-bearing walls within the electrical area can be considered suitable installation areas for distribution boxes.

[0097] S206, Based on the target location, determine at least one target installable area from all installable areas, and determine the location of the target installable area as the installation location for the distribution box.

[0098] The target installable area can be the installable area with the shortest distance to the target location among all installable areas.

[0099] After identifying multiple installable areas, the installable area with the shortest distance to the target location can be selected as the target installable area, and the location of the target installable area can be determined as the installation location of the distribution box.

[0100] In practical applications, once multiple target locations are determined, the target installable area corresponding to each target location can be determined sequentially. Specifically, for each target location, the installable area with the shortest distance from that target location can be selected from all installable areas, thus obtaining the target installable area corresponding to each target location.

[0101] S207, determine the distribution box corresponding to each power distribution list, and determine the equipment pairing relationship between each distribution box and the electrical equipment based on the mapping relationship between the power distribution list and the distribution box.

[0102] After obtaining at least one power distribution list, for each power distribution list, the target location corresponding to the power distribution list can be determined, and the target installation area corresponding to the target location can be determined. Then, the power distribution box installed in the target installation area can be determined as the power distribution box corresponding to the power distribution list, thus obtaining the power distribution box corresponding to each power distribution list.

[0103] After obtaining the distribution box corresponding to each distribution list, the equipment pairing relationship between each distribution box and the electrical equipment can be determined based on the mapping relationship between the distribution list and the distribution box, that is, based on the correspondence between each distribution list and the distribution box.

[0104] In practical applications, for each power distribution list, it is possible to determine all electrical devices in the power distribution list that are powered by the corresponding power distribution box. This allows for the establishment of a pairing relationship between all electrical devices in the power distribution list and the corresponding power distribution box, thus obtaining the device pairing relationship between each power distribution box and the electrical device.

[0105] S208, Based on the equipment pairing relationship and the installation location of the electrical box, generate a power distribution scheme for the building object, and distribute power to the electrical equipment based on the power distribution scheme.

[0106] In this embodiment of the invention, by obtaining the electrical equipment information of each electrical device in a building object from a BIM platform, at least one electrical area in the building object is determined. Based on the equipment load information, equipment location information, and maximum power distribution load of the distribution box of the electrical devices in the electrical area, all electrical devices in the electrical area are divided into at least one power distribution list. Based on the equipment location information of all electrical devices in the electrical area, at least one target location in the electrical area is determined. Multiple installable areas in the electrical area are determined. Based on the target location, at least one target installable area is determined from all installable areas, and the location of the target installable area is determined as the installation location of the distribution box. The distribution box corresponding to each power distribution list is determined, and based on the mapping relationship between the power distribution list and the distribution box, the equipment pairing relationship between each distribution box and the electrical device is determined. Based on the equipment pairing relationship and the installation location of the distribution box, a power distribution scheme for the building object is generated, and power is distributed to the electrical devices based on the power distribution scheme. This enables the generation of a power distribution scheme for the building object based on the electrical equipment information of the electrical devices in the BIM platform, improving the accuracy and efficiency of power distribution design.
