Description

Technical Field

[0001] This invention belongs to the field of substation construction technology, and in particular relates to a method for establishing a substation construction model based on BIM. Background Technology

[0002] Building Information Modeling (BIM) is a novel approach to architectural design and management. It integrates various building information, including structural details, materials, and equipment, to create a digital building model. BIM has a wide range of applications, playing a crucial role in the design, construction, and operation phases of a building. A substation is a location in a power system that transforms voltage and current, receiving and distributing electrical energy. Substations within power plants are step-up substations, whose function is to boost the voltage of electricity generated by generators before feeding it into the high-voltage power grid. During substation construction, a BIM-based construction model is used to provide a more intuitive understanding of the construction process.

[0003] In existing technologies, substation construction models cannot predict the construction progress, nor can they prepare work and materials in advance based on the predicted construction progress, which is not conducive to the construction process.

[0004] Therefore, there is an urgent need for a new technical solution to address this problem. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide a BIM-based method for establishing a substation construction model to address the technical problem in the prior art that the substation construction model cannot predict the construction progress and cannot prepare work and materials in advance based on the predicted construction progress, which is not conducive to the construction process.

[0006] The method for establishing a BIM-based substation construction model includes the following steps, which are performed sequentially:

[0007] S1: Establish a substation construction model and build a system framework. The system framework includes a construction data acquisition module, a BIM platform, a data extraction module, a data filtering module, a data comparison module, a difference judgment module, a substation construction model, a model update module, an update data extraction module, a change calculation module, and a construction prediction module.

[0008] S2: Real-time data of the substation construction process is collected through the construction data acquisition module and transmitted to the BIM platform for integration and storage to achieve information sharing;

[0009] S3: Extract construction data from the BIM platform through the data extraction module, filter out variables that affect the substation construction model through the data filtering module, and construct the substation construction model based on the filtering results;

[0010] S4: The data comparison module compares the data collected when building the construction model with the data collected after building the model. The difference judgment module detects the difference in the data. If a difference is detected, the model update module extracts the difference data and dynamically updates the construction model.

[0011] S5: The difference data is extracted by the data extraction module, the change is quantified by the change calculation module, and the construction prediction module predicts the construction progress based on the daily change.

[0012] The system framework also includes a progress recording module, a progress extraction module, a progress comparison module, a difference calculation module, a prediction accuracy calculation module, a difference cause analysis module, an output display module, and a data storage module;

[0013] The output display module receives the predicted construction progress from the construction prediction module and displays it visually; the progress recording module receives the quantified change from the change calculation module and records the actual construction progress; the progress comparison module extracts the actual construction progress through the progress extraction module and compares it with the predicted construction progress; the difference calculation module quantifies the predicted progress comparison results and traces the root cause of the deviation through the difference cause analysis module; the prediction accuracy calculation module evaluates the reliability of the construction progress prediction based on the predicted progress comparison results; and the data storage module stores the real-time data of the selected variables.

[0014] The progress comparison module includes a predicted progress extraction unit, an actual progress extraction unit, a progress comparison unit, and a report output unit; the report output unit generates a comparison analysis report, which visually displays the deviation between the predicted and actual progress.

[0015] The system framework also includes an identity verification module; the identity verification module includes a construction worker login unit, a management personnel login unit, a supervisor login unit, an information verification unit, and a login authorization unit; the information verification unit controls the scope of data access through set role permissions.

[0016] The construction data acquisition module includes a construction data acquisition unit, a data processing unit, a data classification unit, a traceability registration unit, and a data upload unit. The data types acquired by the construction data acquisition unit include the number of construction personnel, the status of construction equipment, the inventory of construction materials, construction progress milestones, construction drawing versions, and building structural parameters. The data processing unit is used to process the acquired data and remove useless or duplicate data. The data classification unit is used to classify the processed data. The traceability registration unit is used to register the classified data for traceability, marking the data and associating it with the identity of the data acquisition personnel to ensure data traceability.

[0017] The data comparison module includes an initial data extraction unit, a post-construction data extraction unit, a data comparison unit, and an output unit. The initial data extraction unit is used to extract model variable data when building the model. The post-construction data extraction unit is used to extract construction data after the model is built. The data comparison unit is used to compare the two extracted sets of data, and the data comparison unit uses a threshold algorithm to determine whether the data difference triggers a model update.

[0018] The BIM platform includes an information sharing module, a model building module, a simulation module, and a detection and evaluation module. The information sharing module enables construction personnel, management personnel, and supervisors to share substation construction information. The model building module is used to build a three-dimensional building model based on the received data. The simulation module is used to simulate the substation's lighting, ventilation, daylighting, and energy consumption. The detection and evaluation module is used to perform collision detection and structural analysis on the substation.

[0019] The construction prediction module is based on machine learning algorithms and dynamically adjusts the prediction model parameters by combining historical change trends to improve the accuracy of long-term progress prediction.

[0020] The change calculation module is used to output the change amount. If the output change amount exceeds the preset threshold, an early warning signal is triggered, indicating abnormal data collection or deviation from the construction plan, and the model update is suspended until manual verification.

[0021] Through the above design scheme, the present invention can bring the following beneficial effects:

[0022] The construction data acquisition module collects data during the substation construction process and transmits the collected data to the BIM platform. The BIM platform integrates and stores the construction data to achieve information sharing. The data extraction module extracts the substation construction data stored in the BIM platform and transmits the extracted data to the data filtering module. The data filtering module filters the received data to identify variables that affect the substation construction model. The substation construction model is then built based on the data filtered by the data filtering module.

[0023] The data comparison module compares the data collected during the construction model building process with the data collected after the model is built. The comparison data is then transmitted to the difference judgment module, which performs difference analysis on the data. When a difference is found, the model update module extracts the difference data and updates the construction model. The update data extraction module extracts the difference data and transmits the extracted data to the change calculation module. The change calculation module calculates the change and transmits the change to the construction prediction module. The construction prediction module predicts the construction progress based on the daily change.

[0024] This invention can predict the construction progress and prepare work and materials in advance based on the predicted construction progress, so as to ensure the normal and continuous progress of construction. Attached Figure Description
