Description

Technical Field

[0001] This invention belongs to the field of construction progress information management technology, and in particular relates to a method and system for managing substation construction progress information based on BIM technology. Background Technology

[0002] Building Information Modeling (BIM) is a widely used building information tool in the construction field. Based on three-dimensional digital information technology, BIM includes all data from planning, design, construction, and operation stages in a 3D model. It is a detailed digital representation of relevant information for an engineering project. A complete BIM can link data, processes, and resources at different stages of the building project lifecycle. It is a complete description of the engineering object and can be widely used by all parties involved in the construction project.

[0003] In existing technologies, real-time BIM models at different time points are usually compared with standard BIM models. If the comparison is inconsistent, it is determined that the construction progress information at that time point is incorrect or has no reference value. However, in the actual construction process, due to non-human factors, the real-time BIM model at a certain time point may not correspond to the standard BIM model. However, by accelerating the project progress later, the real-time BIM model can be made consistent with the corresponding standard BIM model at other time points. In this case, the construction information at a certain time point and other time points in this process are equally valuable for reference.

[0004] Therefore, there is an urgent need for a substation construction progress information management method and system based on BIM technology to accurately identify the validity of building information at each time point in the entire construction process and to manage the information accordingly based on its validity. Summary of the Invention

[0005] This invention provides a method and system for managing substation construction progress information based on BIM technology, which solves the technical problem that the validity of construction information at each time point in the entire construction process cannot be accurately identified, resulting in low accuracy of substation construction progress information management.

[0006] In a first aspect, the present invention provides a method for managing substation construction progress information based on BIM technology, comprising:

[0007] Obtain construction node information for different substation construction areas at various time nodes within a preset time period, and generate BIM models corresponding to the different substation construction areas based on the construction node information to obtain at least one BIM model sequence, wherein one BIM model sequence is associated with one substation construction area.

[0008] Based on the construction type of each substation construction area, a preset sequence division strategy is used to divide the at least one BIM model sequence to obtain at least one set of BIM model sequences. According to a preset anomaly identification strategy, it is determined whether the number of abnormal BIM models in a certain BIM model sequence is greater than a first preset threshold. The certain BIM model sequence is any sequence in a certain set of BIM model sequences.

[0009] If the number of abnormal BIM models exceeds the first preset threshold, the location information of an abnormal BIM model in a certain BIM model sequence is obtained, and a target BIM model corresponding to the location information is searched in other BIM model sequences. It is then determined whether the number of abnormal target BIM models exceeds the second preset threshold. The abnormal target BIM model is the abnormal BIM model in each target BIM model, and the other BIM model sequence is all BIM model sequences in the set of BIM model sequences excluding the BIM model sequence.

[0010] If it exceeds the second preset threshold, the abnormal construction node information corresponding to the abnormal BIM model is associated with the construction node information of a target BIM model to obtain the target association relationship. The target BIM model is a normal BIM model in the BIM model sequence that is adjacent to the abnormal BIM model and whose time node is greater than the time node of the abnormal BIM model.

[0011] The abnormal construction node information with target association in a certain BIM model sequence and all normal construction node information are stored, and other construction node information is directly transmitted to the user terminal and an alert is issued. The other construction node information is abnormal construction node information without target association.

[0012] Secondly, the present invention provides a substation construction progress information management system based on BIM technology, comprising:

[0013] The acquisition module is configured to acquire construction node information of different substation construction areas at various time nodes within a preset time period, and generate BIM models corresponding to the different substation construction areas based on the construction node information, thereby obtaining at least one BIM model sequence, wherein one BIM model sequence is associated with one substation construction area.

[0014] The first judgment module is configured to divide the at least one BIM model sequence based on the construction type of each substation construction area using a preset sequence division strategy to obtain at least one set of BIM model sequences, and to determine whether the number of abnormal BIM models in a certain BIM model sequence is greater than a first preset threshold according to a preset anomaly identification strategy, wherein the certain BIM model sequence is any sequence in a certain set of BIM model sequences.

[0015] The second judgment module is configured to, if the number of abnormal BIM models exceeds a first preset threshold, obtain a location information of an abnormal BIM model in a certain BIM model sequence, search for a target BIM model corresponding to the location information in other BIM model sequences, and determine whether the number of abnormal target BIM models exceeds a second preset threshold. The abnormal target BIM model is an abnormal BIM model among the various target BIM models, and the other BIM model sequences are all BIM model sequences in the set of certain BIM model sequences excluding the certain BIM model sequence.

[0016] The association module is configured to, if the value is greater than a second preset threshold, associate the abnormal construction node information corresponding to a certain abnormal BIM model with the construction node information of a certain target BIM model according to a preset association strategy to obtain a target association relationship. The certain target BIM model is a normal BIM model in the certain BIM model sequence that is adjacent to the certain abnormal BIM model and whose time node is greater than the time node of the certain abnormal BIM model.

[0017] The management module is configured to store abnormal construction node information with target association in a certain BIM model sequence, as well as all normal construction node information, and directly transmit other construction node information to the user terminal and issue an alert. The other construction node information refers to abnormal construction node information without target association.

[0018] Thirdly, an electronic device is provided, comprising: at least one processor and a memory communicatively connected to the at least one processor, wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the steps of the substation construction progress information management method based on BIM technology according to any embodiment of the present invention.

[0019] Fourthly, the present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein when the program instructions are executed by a processor, the processor performs the steps of the substation construction progress information management method based on BIM technology according to any embodiment of the present invention.

[0020] This application discloses a BIM-based substation construction progress information management method and system. The method determines the sequence coupling degree of each BIM model sequence in a given BIM model sequence cluster set, and further clusters each sequence coupling degree according to different coupling ranges to obtain at least one sequence coupling degree cluster set. Based on this at least one sequence coupling degree cluster set, the method further divides the given BIM model sequence cluster set to obtain at least one BIM model sequence set. This approach can cluster BIM model sequences with similar construction progress as much as possible, and search for target BIM models corresponding to a certain location information among other BIM model sequences. The purpose is to find abnormal target BIM models with the same or similar construction behaviors. By determining whether the number of abnormal target BIM models exceeds a second preset threshold, the method can accurately identify whether the cause of an abnormal BIM model is accidental or not accidental, and then implement different information management methods. In summary, this invention can effectively improve the accuracy and decision-making efficiency of substation construction progress information management, providing reliable support for the digital management of the entire lifecycle of engineering projects.

[0024] Figure 3 This is a schematic diagram of the structure of an electronic device provided in an embodiment of the present invention. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1The diagram shows a flowchart of a substation construction progress information management method based on BIM technology according to this application.

[0027] like Figure 1 As shown, the substation construction progress information management method based on BIM technology specifically includes the following steps:

[0028] Step S101: Obtain construction node information for different substation construction areas at various time nodes within a preset time period, and generate BIM models corresponding to the different substation construction areas based on the construction node information, thereby obtaining at least one BIM model sequence, wherein one BIM model sequence is associated with one substation construction area.

[0029] In this step, there are multiple construction areas during the substation construction process, such as the main control building construction area, the 220kV power distribution equipment construction area, the 500kV transformer area, and the cable trench area. Therefore, all of these areas are defined as substation construction areas. One time node corresponds to one BIM model; therefore, a substation construction area will generate different BIM models at different time nodes. The BIM models from different time nodes are then sorted according to chronological order to obtain a sequence of BIM models corresponding to the substation construction areas.

[0030] Construction milestone information can be, but is not limited to, textual information. For example, it can be recorded daily or at regular intervals at the construction site and stored in a management computer. This means recording and storing current construction milestone information, such as the name, location, and planned number of days for the substation construction area B currently under construction. During project supervision, supervisors can retrieve construction milestone information, such as the name of the substation construction area B currently under construction, from the management computer, and then obtain the corresponding BIM model of the substation construction area B based on the name of building component B. In other embodiments, construction milestone information can be obtained by computer recognition based on images of the current construction site.

[0031] Step S102: Based on the construction type of each substation construction area, the at least one BIM model sequence is divided using a preset sequence division strategy to obtain at least one set of BIM model sequences. Then, according to a preset anomaly identification strategy, it is determined whether the number of abnormal BIM models in a certain BIM model sequence is greater than a first preset threshold. The certain BIM model sequence is any sequence in a certain set of BIM model sequences.

[0032] In this step, within substation construction management, construction type refers to the professional classification of construction areas based on process characteristics, resource requirements, or risk levels. Specific implementation must adhere to power construction standards (such as GB50966-2014). For example, the main structure construction area (e.g., main control building construction area, firewall construction area) is defined as a civil engineering type; the high-voltage equipment installation construction area (e.g., 220kV power distribution equipment construction area) is defined as an electrical type; and the concealed works construction area (e.g., cable trench area) is defined as a comprehensive type.

[0033] It should be noted that the construction types of each substation construction area are obtained, and at least one BIM model sequence corresponding to the same construction type is clustered to obtain at least one BIM model sequence cluster set; the sequence coupling degree of each BIM model sequence in a certain BIM model sequence cluster set is determined, and each sequence coupling degree is clustered again according to different coupling ranges to obtain at least one sequence coupling degree cluster set; based on at least one sequence coupling degree cluster set, a certain BIM model sequence cluster set is divided to obtain at least one BIM model sequence set, wherein the sequence coupling degree of each BIM model sequence in a BIM model sequence set is within the same coupling range.

[0034] For example, within a preset time period, the BIM model sequence corresponding to the main control building construction area is the first BIM model sequence (first BIM model a1, first BIM model a2, first BIM model a3, first BIM model a4); within a preset time period, the BIM model sequence corresponding to the firewall construction area is the second BIM model sequence (second BIM model b1, second BIM model b2, second BIM model b3, second BIM model b4).

[0035] Furthermore, the first BIM model in a certain BIM model sequence is defined as the initial BIM model. The model similarity between other BIM models in a certain BIM model sequence and the initial BIM model, as well as the time interval between other BIM models and the initial BIM model, are obtained. The ratio of model similarity to time interval is calculated to obtain the coupling degree of each model. The coupling degrees of each model are added together to obtain the sequence coupling degree of a certain BIM model sequence.

[0036] The process for determining model similarity is as follows:

[0037] Convert the BIM model to a standard format (such as IFC) and extract key components (e.g., extract only the components relevant to the current construction phase).

[0038] Lightweighting of the BIM model involves removing unnecessary details (such as bolts, welds, and other small components).

[0039] Feature extraction:

[0040] Geometric features: the bounding box, volume, surface area, etc. of the computational model.

[0041] Attribute characteristics: Extract the attributes of key components, such as type, status (under construction, completed), material, etc.

[0042] Topological features: Extracting the connection relationships between components (such as the connection between pipes and valves).

[0043] Similarity calculation:

[0044] For two BIM models (BIM model A and BIM model B), the above features are extracted respectively, and then compared.

[0045] Geometric similarity: Calculates the bounding box overlap rate of corresponding components of two models, where the expression is: Geometric similarity = (volume of BIM model A ∩ volume of BIM model B) / (volume of BIM model A ∪ volume of BIM model B), where ∩ represents the intersection and ∪ represents the union;

[0046] Attribute similarity: Cosine similarity is used to calculate the similarity of attribute vectors. The attributes of each component (such as type encoding, state encoding, etc.) are combined into a vector, then the similarity of the attribute vectors of corresponding components in the two models is calculated, and the average value is taken.

[0047] Topological similarity: Compares the connection graphs of two BIM models. Graph similarity is calculated using graph matching algorithms such as Graph EditDistance.

[0048] Model similarity:

[0049] The weighted average of the geometric similarity, attribute similarity, and topological similarity is expressed as: Model Similarity = w1 * Geometric Similarity + w2 * Attribute Similarity + w3 * Topological Similarity, where w1, w2, and w3 are the weights of geometric similarity, attribute similarity, and topological similarity, respectively. w1, w2, and w3 can be adjusted according to the construction type. For example, in the civil construction phase, geometric similarity has a higher weight; in the equipment installation phase, attribute similarity and topological similarity have higher weights.

[0050] For example, the first BIM model sequence (first BIM model a1, first BIM model a2, first BIM model a3, first BIM model a4), and the second BIM model sequence (second BIM model b1, second BIM model b2, second BIM model b3, second BIM model b4).

[0051] The model similarity between BIM models a1 and a2, a3 and a4 in the first BIM model sequence is determined separately. The ratio between each model similarity and its corresponding time interval is calculated to obtain the coupling degree of each model. These coupling degrees are then summed to obtain the sequence coupling degree of the first BIM model sequence. Similarly, the sequence coupling degree of the second BIM model sequence can be obtained.

[0052] Furthermore, based on a preset anomaly detection strategy, determining whether the number of abnormal BIM models in a given BIM model sequence exceeds a first preset threshold includes:

[0053] The process involves obtaining the model similarity between each BIM model in a given BIM model sequence and its corresponding standard BIM model, and determining whether the similarity of each model is greater than a preset similarity threshold. If the similarity of a model is not greater than the preset similarity threshold, the BIM model corresponding to that model is defined as an abnormal BIM model; otherwise, the BIM model is defined as a normal BIM model. The process also determines whether the number of abnormal BIM models in a given BIM model sequence exceeds a first preset threshold. The corresponding standard BIM model refers to the standard BIM model corresponding to different time points. The model similarity between each BIM model and its corresponding standard BIM model can also be obtained using the formula: "Model Similarity = w1 * Geometric Similarity + w2 * Attribute Similarity + w3 * Topological Similarity".

[0054] In this embodiment, the first BIM model is used as a benchmark anchor point. By calculating the ratio of the similarity between subsequent models and the benchmark to the time interval, the rate at which the progress status deviates from the original plan per unit time is accurately quantified. This allows BIM model sequences with the same rate to be grouped into the same set. This makes it easier to determine whether the cause of an abnormal BIM model in a certain BIM model sequence is accidental or non-accidental, based on the analysis results of whether other BIM models at the same time node are normal, after the number of abnormal BIM models in a certain BIM model sequence exceeds a first preset threshold. This allows for the implementation of different management strategies.

[0055] In one specific embodiment, after determining whether the number of abnormal BIM models in a certain BIM model sequence exceeds a first preset threshold, if it does not exceed the first preset threshold, the construction node information corresponding to the normal BIM models in the certain BIM model sequence is stored, and the construction node information corresponding to the abnormal BIM models in the certain BIM model sequence is directly transmitted to the user terminal with an alert. In this way, even if an abnormal BIM model in a certain BIM model sequence is misjudged, the small amount of transmitted construction node information allows the user to quickly re-identify the cause of the abnormal BIM model, and based on the identification result, the user can perform manual storage or other operations.

[0056] Step S103: If the number of abnormal BIM models exceeds the first preset threshold, obtain the location information of an abnormal BIM model in the BIM model sequence, search for the target BIM model corresponding to the location information in other BIM model sequences, and determine whether the number of abnormal target BIM models exceeds the second preset threshold. The abnormal target BIM model is the abnormal BIM model among the target BIM models, and the other BIM model sequences are all BIM model sequences in the BIM model sequence set after removing the BIM model sequence.

[0057] In one specific embodiment, after determining whether the number of abnormal target BIM models is greater than a second preset threshold, if it is not greater than the second preset threshold, then it is determined whether the BIM model adjacent to the abnormal BIM model in the BIM model sequence is a normal BIM model; if it is a normal BIM model, then the abnormal construction node information corresponding to the abnormal BIM model is directly transmitted to the user terminal and an alert is issued; if it is not a normal BIM model, then the abnormal construction node information corresponding to the abnormal BIM model is associated with the construction node information corresponding to the adjacent BIM models to obtain an abnormal association relationship, and the construction node information corresponding to the abnormal BIM model is stored according to the abnormal association relationship.

[0058] For example, if the number of abnormal target BIM models is no greater than a second preset threshold, it indicates that the cause of the BIM model abnormality at that time point may be due to human factors. To determine whether it is caused by human factors, it is necessary to check whether the BIM models adjacent to an abnormal BIM model in a certain BIM model sequence are normal BIM models. If the adjacent BIM models are normal BIM models, it indicates that it is highly likely due to errors in the collection of construction node information or other human factors, resulting in the abnormality of the BIM model built at that time point. Therefore, it is necessary to issue a warning to the user so that the user can adjust the BIM model at that time point. If the adjacent BIM models are abnormal BIM models, it indicates that it is highly likely due to non-human factors (weather factors). Therefore, even if the BIM model is abnormal at this time, its corresponding construction node information is still valuable for reference and needs to be stored.

[0059] It should be noted that, based on the abnormal association relationship, the construction node information corresponding to a certain abnormal BIM model is stored as follows:

[0060] Suppose that a certain abnormal BIM model, a first BIM model, and a second BIM model are all abnormal. The first and second BIM models are adjacent to the abnormal BIM model. Therefore, anomaly relationships are constructed and stored between the construction node information corresponding to the abnormal BIM model, the first construction node information corresponding to the first BIM model, and the second construction node information corresponding to the second BIM model. This allows for subsequent synchronous queries of the construction node information, the first construction node information, and the second construction node information through these anomaly relationships, enabling the retrieval of the entire change process of the abnormal construction node information.

[0061] Step S104: If the value is greater than the second preset threshold, then the abnormal construction node information corresponding to the abnormal BIM model is associated with the construction node information of a target BIM model to obtain the target association relationship. The target BIM model is a normal BIM model in the BIM model sequence that is adjacent to the abnormal BIM model and whose time node is greater than the time node of the abnormal BIM model.

[0062] Step S105: Store the abnormal construction node information with target association in a certain BIM model sequence and all normal construction node information, and directly transmit the other construction node information to the user terminal and issue an alert. The other construction node information is abnormal construction node information without target association.

[0063] In this step, an abnormal BIM model is associated with a target BIM model and stored. When a user queries the abnormal construction node information corresponding to an abnormal BIM model, the normal construction node information of the target BIM model can be displayed simultaneously. This enables a full lifecycle assessment and is more practical than querying a single abnormal construction node.

[0064] In summary, the method of this application determines the sequence coupling degree of each BIM model sequence in a certain BIM model sequence cluster set, and further clusters each sequence coupling degree according to different coupling ranges to obtain at least one sequence coupling degree cluster set. Based on at least one sequence coupling degree cluster set, the certain BIM model sequence cluster set is divided to obtain at least one BIM model sequence set. This method can cluster BIM model sequences with the same construction progress as much as possible, and search for target BIM models corresponding to a certain location information in other BIM model sequences. The purpose is to find abnormal target BIM models with the same or similar construction behavior. By judging whether the number of abnormal target BIM models is greater than a second preset threshold, it is possible to more accurately identify whether the cause of a certain abnormal BIM model is accidental (information entry error) or non-accidental (severe weather prevents construction), and then execute different information management methods. In summary, this invention can effectively improve the accuracy and decision-making efficiency of substation construction progress information management, and provide reliable support for the digital management of the entire life cycle of engineering projects.

[0069] In other embodiments, the present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein when the program instructions are executed by a processor, the processor performs the substation construction progress information management method based on BIM technology in any of the above method embodiments.

[0070] In one embodiment, the computer-readable storage medium of the present invention stores computer-executable instructions, which are configured as follows:

[0071] Obtain construction node information for different substation construction areas at various time nodes within a preset time period, and generate BIM models corresponding to the different substation construction areas based on the construction node information to obtain at least one BIM model sequence, wherein one BIM model sequence is associated with one substation construction area.

[0072] Based on the construction type of each substation construction area, a preset sequence division strategy is used to divide the at least one BIM model sequence to obtain at least one set of BIM model sequences. According to a preset anomaly identification strategy, it is determined whether the number of abnormal BIM models in a certain BIM model sequence is greater than a first preset threshold. The certain BIM model sequence is any sequence in a certain set of BIM model sequences.

[0073] If the number of abnormal BIM models exceeds the first preset threshold, the location information of an abnormal BIM model in a certain BIM model sequence is obtained, and a target BIM model corresponding to the location information is searched in other BIM model sequences. It is then determined whether the number of abnormal target BIM models exceeds the second preset threshold. The abnormal target BIM model is the abnormal BIM model in each target BIM model, and the other BIM model sequence is all BIM model sequences in the set of BIM model sequences excluding the BIM model sequence.

[0074] If it exceeds the second preset threshold, the abnormal construction node information corresponding to the abnormal BIM model is associated with the construction node information of a target BIM model to obtain the target association relationship. The target BIM model is a normal BIM model in the BIM model sequence that is adjacent to the abnormal BIM model and whose time node is greater than the time node of the abnormal BIM model.

[0075] The abnormal construction node information with target association in a certain BIM model sequence and all normal construction node information are stored, and other construction node information is directly transmitted to the user terminal and an alert is issued. The other construction node information is abnormal construction node information without target association.

[0079] In one implementation, the aforementioned electronic device is used in a BIM-based substation construction progress information management system for a client application, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to:

[0080] Obtain construction node information for different substation construction areas at various time nodes within a preset time period, and generate BIM models corresponding to the different substation construction areas based on the construction node information to obtain at least one BIM model sequence, wherein one BIM model sequence is associated with one substation construction area.

[0081] Based on the construction type of each substation construction area, a preset sequence division strategy is used to divide the at least one BIM model sequence to obtain at least one set of BIM model sequences. According to a preset anomaly identification strategy, it is determined whether the number of abnormal BIM models in a certain BIM model sequence is greater than a first preset threshold. The certain BIM model sequence is any sequence in a certain set of BIM model sequences.

[0082] If the number of abnormal BIM models exceeds the first preset threshold, the location information of an abnormal BIM model in a certain BIM model sequence is obtained, and a target BIM model corresponding to the location information is searched in other BIM model sequences. It is then determined whether the number of abnormal target BIM models exceeds the second preset threshold. The abnormal target BIM model is the abnormal BIM model in each target BIM model, and the other BIM model sequence is all BIM model sequences in the set of BIM model sequences excluding the BIM model sequence.

[0083] If it exceeds the second preset threshold, the abnormal construction node information corresponding to the abnormal BIM model is associated with the construction node information of a target BIM model to obtain the target association relationship. The target BIM model is a normal BIM model in the BIM model sequence that is adjacent to the abnormal BIM model and whose time node is greater than the time node of the abnormal BIM model.

[0084] The abnormal construction node information with target association in a certain BIM model sequence and all normal construction node information are stored, and other construction node information is directly transmitted to the user terminal and an alert is issued. The other construction node information is abnormal construction node information without target association.

Based on the construction type of each substation construction area, a preset sequence division strategy is used to divide the at least one BIM model sequence to obtain at least one set of BIM model sequences. According to a preset anomaly identification strategy, it is determined whether the number of abnormal BIM models in a certain BIM model sequence is greater than a first preset threshold. The certain BIM model sequence is any sequence in a certain set of BIM model sequences. If the number of abnormal BIM models exceeds the first preset threshold, the location information of an abnormal BIM model in a certain BIM model sequence is obtained, and a target BIM model corresponding to the location information is searched in other BIM model sequences. It is then determined whether the number of abnormal target BIM models exceeds the second preset threshold. The abnormal target BIM model is the abnormal BIM model in each target BIM model, and the other BIM model sequence is all BIM model sequences in the set of BIM model sequences excluding the BIM model sequence. If it exceeds the second preset threshold, the abnormal construction node information corresponding to the abnormal BIM model is associated with the construction node information of a target BIM model to obtain the target association relationship. The target BIM model is a normal BIM model in the BIM model sequence that is adjacent to the abnormal BIM model and whose time node is greater than the time node of the abnormal BIM model. The abnormal construction node information with target association in a certain BIM model sequence and all normal construction node information are stored, and other construction node information is directly transmitted to the user terminal and an alert is issued.
