Description

TECHNICAL FIELD

[0002] Building Information Modeling (BIM) is a building informatization tool widely used in the field of building. BIM is based on three-dimensional digital information technology, and data of all stages such as planning, design, construction and operation are contained in a 3D model. BIM is a detailed digital expression of information related to a project. A complete BIM can associate data, processes and resources at different stages of a building project life cycle, and is a complete description of an engineering object that can be used by all parties involved in a construction project.

[0003] In the prior art, real-time BIM models at different time nodes are compared with standard BIM models. If the comparison is inconsistent, it is determined that the construction progress information input at the time node is incorrect or does not have reference value. However, in the actual construction process, the real-time BIM model at a time node may not correspond to the standard BIM model due to non-human factors. However, in the later stage, the real-time BIM model is consistent with the corresponding standard BIM model at other time nodes by accelerating the progress of the project. At this time, the construction information at the time node and the other time nodes in the process also has reference value.

[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 effectiveness of the construction information at each time node in the entire construction process and manage the information accordingly based on the effectiveness.

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the application more clear, the following will combine the drawings in the embodiments of the application to clearly and completely describe the technical solutions in the embodiments of the application. Obviously, the described embodiments are some embodiments of the application, not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the application.

[0014] Please refer to Figure 1It shows a flow chart of a substation construction progress information management method based on BIM technology.

[0015] As shown in Figure 1 The substation construction progress information management method based on BIM technology specifically includes the following steps: Step S101, obtain the construction node information of different substation construction areas at each time node in a preset time period, and generate a BIM model corresponding to the different substation construction areas according to the construction node information, to obtain at least one BIM model sequence, wherein one BIM model sequence is associated with one substation construction area.

[0016] In this step, there are multiple construction areas in the substation construction process, for example, main control building construction area, 220kV power distribution device construction area, 500kV transformer area and cable channel area, therefore, the above areas are all defined as substation construction areas. One time node corresponds to one BIM model, therefore, different BIM models of one substation construction area are generated at different time nodes, and the BIM models of different time nodes are sorted based on the time sequence, to obtain the BIM model sequence corresponding to the substation construction area.

[0017] The construction node information can be but is not limited to text information, for example, recorded and stored in the management computer by the construction management personnel every day or at intervals of a certain number of days at the construction site, that is, to record and store the current construction node information, such as the name, location and construction plan days of the substation construction area B currently under construction. During project supervision, the supervisor can obtain the construction node information such as the name of the substation construction area B currently under construction from the management computer, and then obtain the BIM model of the corresponding substation construction area B based on the name of the building component B. In other embodiments, the construction node information can be obtained by computer recognition based on the current construction site image.

[0018] Step S102, based on the construction type of each substation construction area, the at least one BIM model sequence is divided by using a preset sequence division strategy to obtain at least one BIM model sequence set, and according to a preset abnormality identification strategy, it is judged whether the number of abnormal BIM models in a certain BIM model sequence is greater than a first preset threshold, wherein the certain BIM model sequence is any sequence in a certain BIM model sequence set.

[0019] In this step, in the substation construction management, the construction type refers to the professional classification of the construction area according to the process characteristics, resource demand or risk level. The specific implementation needs to be combined with the electric power construction specification (such as GB50966-2014). For example, the main structure construction area (such as the main control building construction area, the fire wall construction area) is defined as the civil engineering type; the high-voltage equipment installation construction area (such as the 220kV power distribution device construction area) is defined as the electrical type; and the concealed engineering construction area (such as the cable channel area) is defined as the comprehensive type.

[0020] It should be noted that the construction type of each substation construction area is obtained, and at least one BIM model sequence corresponding to the same construction type is clustered to obtain at least one BIM model sequence clustering set; the sequence coupling degree of each BIM model sequence in a certain BIM model sequence clustering set is determined, and each sequence coupling degree is further clustered according to different coupling ranges to obtain at least one sequence coupling degree clustering set; a certain BIM model sequence clustering set is divided based on the at least one sequence coupling degree clustering set to obtain at least one BIM model sequence set, wherein the sequence coupling degrees of the BIM model sequences in a BIM model sequence set are within the same coupling range.

[0021] For example, the BIM model sequence corresponding to the main control building construction area within the preset time period is the first BIM model sequence (first BIM model a1, first BIM model a2, first BIM model a3, first BIM model a4); and the BIM model sequence corresponding to the fire wall construction area within the preset time period is the second BIM model sequence (second BIM model b1, second BIM model b2, second BIM model b3, second BIM model b4).

[0022] Further, the first BIM model in a certain BIM model sequence is defined as an initial BIM model, the model similarity between other BIM models in the certain BIM model sequence and the initial BIM model is obtained, as well as the time interval between the other BIM models and the initial BIM model, the ratio of the model similarity and the time interval is calculated to obtain each model coupling degree, and each model coupling degree is added to obtain a certain sequence coupling degree of a certain BIM model sequence.

[0023] The determination process of the model similarity is as follows: The BIM model is converted into a standard format (such as IFC), and the key components (for example, only the components related to the current construction stage are extracted).

[0024] The BIM model is subjected to lightweight processing, and unnecessary details (such as bolts, welds and other small components) are removed.

[0025] Feature extraction: Geometric features: Calculate the bounding box, volume, surface area, etc. of the model.

[0026] Attribute features: Extract the attributes of key components, such as type, status (under construction, completed), material, etc.

[0027] Topological features: Extract the connection relationship between components (such as the connection between pipes and valves).

[0028] Similarity calculation: For two BIM models (BIM model A and BIM model B), extract the above features respectively, and then compare them.

[0029] Geometric similarity: Calculate the overlap rate of the bounding boxes of the corresponding components of the two models, where the expression is: geometric similarity = (volume of BIM model A ∩ BIM model B) / (volume of BIM model A ∪ BIM model B), ∩ represents intersection, and ∪ represents union. Attribute similarity: Calculate the similarity of attribute vectors using cosine similarity. The attributes of each component (such as type code, status code, etc.) are composed into a vector, and then the attribute vector similarity of the corresponding components of the two models is calculated, and the average value is taken.

[0030] Topological similarity: Compare the connection graphs of the two BIM models. Use graph matching algorithms (such as Graph Edit Distance) to calculate the similarity of the graphs.

[0031] Model similarity: Weighted average the above geometric similarity, attribute similarity and topological similarity, the expression is: model similarity = w1 * geometric similarity + w2 * attribute similarity + w3 * topological similarity, w1, w2, w3 are the weights of geometric similarity, attribute similarity and topological similarity respectively. w1, w2, w3 can be adjusted according to the construction type. For example, in the civil construction stage, the geometric similarity weight is higher; in the equipment installation stage, the attribute similarity and topological similarity weights are higher.

[0032] For example, the first BIM model sequence (first BIM model a1, first BIM model a2, first BIM model a3, first BIM model a4), the second BIM model sequence (second BIM model b1, second BIM model b2, second BIM model b3, second BIM model b4).

[0033] The model similarity between the first BIM model a1 and the first BIM model a2, the model similarity between the first BIM model a1 and the first BIM model a3, and the model similarity between the first BIM model a1 and the first BIM model a4 in the first BIM model sequence are determined respectively. The ratio between each model similarity and the corresponding time interval is calculated to obtain each model coupling degree, and each model coupling degree is added 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.

[0034] In addition, according to the preset abnormal identification strategy, whether the number of abnormal BIM models in a BIM model sequence is greater than a first preset threshold includes: The model similarity between each BIM model in a BIM model sequence and the corresponding standard BIM model is obtained, and whether each model similarity is greater than a preset similarity threshold is determined. If a certain model similarity is not greater than the preset similarity threshold, a certain BIM model corresponding to the certain model similarity is defined as an abnormal BIM model, otherwise the certain BIM model is defined as a normal BIM model. Whether the number of abnormal BIM models in a BIM model sequence is greater than a first preset threshold is determined. The corresponding standard BIM model refers to the standard BIM model corresponding to different time nodes, and the model similarity between each BIM model and the corresponding standard BIM model can also be obtained according to "model similarity = w1*geometric similarity + w2*attribute similarity + w3*topological similarity".

[0035] In this embodiment, the first BIM model is taken as a reference anchor point, and by calculating the similarity ratio between the subsequent model and the reference and the time interval, the rate of progress state deviation from the original plan in unit time is accurately quantified, so that each BIM model sequence with the same rate is divided into the same set, which facilitates determining whether the cause of a certain abnormal BIM model in a certain BIM model sequence is accidental or non-accidental according to the analysis result of whether the BIM model of other same time nodes is normal when the number of abnormal BIM models in a certain BIM model sequence is greater than a first preset threshold, so as to execute different management strategies.

[0036] In one specific embodiment, after judging whether the number of abnormal BIM models in a certain BIM model sequence is greater than a first preset threshold, if it is not greater than 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 end and pre-alarmed. In this way, even if the abnormal BIM models in a certain BIM model sequence are misjudged, the user can quickly identify the cause of the abnormal BIM models again due to the small amount of data of the transmitted construction node information, and according to the identification result, the user can perform manual storage or other operations.

[0037] In step S103, if it is greater than the first preset threshold, the position information of a certain abnormal BIM model in the certain BIM model sequence is obtained, the target BIM models corresponding to the position information are searched in other BIM model sequences, and it is judged whether the number of abnormal target BIM models is greater than a second preset threshold, wherein the abnormal target BIM models are abnormal BIM models in each target BIM model, and the other BIM model sequences are all BIM model sequences after the certain BIM model sequence is removed from the certain BIM model sequence set.

[0038] In one specific embodiment, after judging whether the number of abnormal target BIM models is greater than the second preset threshold, if it is not greater than the second preset threshold, it is judged whether the BIM model adjacent to the certain abnormal BIM model in the certain BIM model sequence is a normal BIM model; if it is a normal BIM model, the abnormal construction node information corresponding to the certain abnormal BIM model is directly transmitted to the user end and pre-alarmed; if it is not a normal BIM model, the abnormal construction node information corresponding to the certain abnormal BIM model is associated with the construction node information corresponding to the BIM model adjacent to the certain abnormal BIM model to obtain an abnormal association relationship, and the construction node information corresponding to the certain abnormal BIM model is stored according to the abnormal association relationship.

[0039] For example, when the number of abnormal target BIM models is not greater than the second preset threshold, it indicates that the cause of the abnormal BIM model at the time node is probably caused by human factors. In order to identify whether it is caused by human factors, at this time, it is judged whether the BIM model adjacent to the abnormal BIM model in a certain BIM model sequence is a normal BIM model. If the adjacent BIM model is a normal BIM model, it indicates that it is probably caused by construction node information collection error or other human factors, thereby causing the abnormal BIM model constructed at the time node, and therefore, the user needs to be warned to adjust the BIM model at the time node. If the adjacent BIM model is an abnormal BIM model, it indicates that it is probably caused by non-human factors (weather factors), and therefore, even if the BIM model at this time is abnormal, the corresponding construction node information is also of reference value, and therefore, needs to be stored.

[0040] It should be noted that the storage of the construction node information corresponding to the abnormal BIM model according to the abnormal association relationship is specifically: Suppose that a certain abnormal BIM model, a first BIM model and a second BIM model are all abnormal, wherein the first BIM model and the second BIM model are two BIM models adjacent to the certain abnormal BIM model, therefore, the abnormal association relationship between the certain construction node information corresponding to the certain 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 is constructed and stored, so that the certain construction node information, the first construction node information and the second construction node information can be synchronously queried through the abnormal association relationship in the subsequent, so that the change process of the entire abnormal construction node information can be obtained.

[0041] In step S104, if greater than the second preset threshold, the abnormal construction node information corresponding to the certain abnormal BIM model is associated with the construction node information of a certain target BIM model to obtain a target association relationship, wherein the certain target BIM model is a normal BIM model adjacent to the certain abnormal BIM model and having a time node greater than that of the certain abnormal BIM model in the certain BIM model sequence.

[0042] In step S105, the abnormal construction node information with the target association relationship and all normal construction node information in the certain BIM model sequence are stored, and other construction node information is directly transmitted to the user end and warned, wherein the other construction node information is abnormal construction node information without the target association relationship.

[0043] In this step, an abnormal BIM model is associated with a target BIM model and stored, and when the user queries the abnormal construction node information corresponding to the abnormal BIM model, the normal construction node information of the target BIM model can be displayed synchronously, so that the whole life cycle can be evaluated, which has more practical significance than querying single abnormal construction node information.

[0044] To sum up, the method of the application determines the sequence coupling degree of each BIM model sequence in a certain BIM model sequence clustering set, and re-clusters each sequence coupling degree according to different coupling ranges to obtain at least one sequence coupling degree clustering set, and divides a certain BIM model sequence clustering set based on the at least one sequence coupling degree clustering set to obtain at least one BIM model sequence set, which can cluster BIM model sequences with the same construction progress as much as possible, and find a target BIM model corresponding to a certain position information in other BIM model sequences, the purpose of which is to find an abnormal target BIM model with the same or similar construction behavior, and by judging whether the number of abnormal target BIM models is greater than a second preset threshold value, it can be more accurately distinguished whether the reason for the existence of a certain abnormal BIM model is accidental (information input error) or non-accidental (bad weather leading to inability to construct), and then different information management methods are executed, and to sum up, the application can effectively improve the accuracy and decision-making efficiency of the substation construction progress information management, and provides reliable support for the whole life cycle digital management of the engineering project.
