Description

Technical Field

[0001] The present invention relates to the technical field of construction informationization, and in particular to a construction informationization management system and method based on BIM. Background Art

[0002] Building information modeling technology is widely used in construction, changing the traditional building design and construction methods and improving efficiency and accuracy. During the construction process, the software integrates on-site data collection and feedback functions, and uses drones, sensors and other data collection equipment on the construction site to capture progress in real time and compare and analyze with the BIM model to control the construction progress and detect damage in a timely manner.

[0003] There are two ways to compare information on the construction site. One is to compare the latest collected data with the old data collected before, and then compare and analyze the changed part with the BIM model. The other is to directly compare and analyze the latest data with the BIM model. The first method will be very fast in the early stage of data collection, but the amount of analysis will increase. The second method only needs to be compared and analyzed once, but the analysis will always be slow. The existing technology generally only adopts one of the solutions in a certain construction, and cannot better avoid the shortcomings of both. Therefore, it is necessary to design a BIM-based construction information management system and method that takes into account both analysis accuracy and speed. Summary of the invention

[0004] The purpose of the present invention is to provide a BIM-based construction information management system and method to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a BIM-based construction information management system and method, including a BIM model analysis module, an information management module, and a comparison implementation module. The BIM model analysis module is used to import the BIM finished model and analyze the data volume and structural complexity of each BIM finished model. The information management module is used to determine the information comparison method of the BIM model in combination with time information. The comparison implementation module uses drones and sensors to collect BIM model information at the construction site and compares it with the BIM finished model, as well as determines the frequency of components in the BIM model participating in the information comparison according to the construction progress.

[0006] According to the above technical solution, the BIM model analysis module includes a model import module, a data volume statistics module, a structural complexity statistics module, and a component annotation module. The model import module is electrically connected to the data volume statistics module, the structural complexity statistics module, and the component annotation module. The model import module is responsible for importing the BIM finished model data for subsequent analysis. The data volume statistics module is used to count and evaluate the size of the space occupied by the BIM finished model to obtain the volume of the BIM finished model. The structural complexity statistics module is used to analyze the component complexity of the BIM finished model. The component annotation module is used to mark and distinguish each component in the BIM finished model.

[0007] The information management module includes a completed construction statistics module, a comparison speed calculation module, and a comparison method determination module. The comparison method determination module is electrically connected to the comparison speed calculation module. The completed construction statistics module is used to count the progress information during the construction process. The comparison speed calculation module is used to calculate the comparison speed according to the current data volume and structural complexity of the BIM model. The comparison method determination module is used to determine the method of comparing the BIM model information of the construction site with the BIM finished product model information;

[0008] The comparison implementation module includes an information collection module, an information comparison module, and a comparison participation decision module. The information collection module is electrically connected to the comparison method determination module and the information comparison module. The comparison participation decision module is electrically connected to the component marking module. The information collection module is used to receive the BIM model information collected at the construction site. The information comparison module is used to compare the BIM model information collected at the construction site with the BIM finished product model to determine whether they are in compliance. The comparison participation decision module is used to determine the frequency of component participation in information comparison in the BIM model.

[0009] BIM-based construction information management methods include:

[0010] S1. Import the BIM finished model data through the model import module, count and evaluate the space occupied by the imported BIM finished model, count the complexity of the BIM finished model, mark and distinguish each component in the BIM finished model, and derive the properties of each component;

[0011] S2. During the construction process, the BIM model information collected at the construction site is compared with the BIM finished model to determine whether it is in compliance, control the construction progress and detect damage in a timely manner;

[0012] S3. Collect progress information during the construction process to obtain the data volume and structural complexity of the current BIM model, and decide whether the BIM model should adopt an analysis mode that compares the latest data with the previous data or a mode that directly compares and analyzes with the BIM model under the current progress.

[0013] S4. According to the properties of the components in the BIM model, the frequencies of participating in the comparison and analysis are set for the components in the BIM model.

[0014] According to the above technical solution, in S1, the calculation method of the space occupied by the BIM finished model is as follows: first, the overall space occupied by the BIM finished model ∑S is calculated. i That is, the amount of data. Then, the sizes of each component in the BIM finished model are {S1, S2, …, S i}, read the connection relationship file in the BIM finished model. The complexity of the BIM finished model is the number of connection relationships between components R, where the number of connection relationships involved in each component is {R1, R2, …, R i}, where i is the number of components. Since each component has at least one connection relationship and there must be components with more than two connection relationships, ∑R i >R.

[0015] According to the above technical solution, in S3, the specific method for obtaining the data volume and structural complexity of the current BIM model is:

[0016] S3-1. As long as the components in the BIM model of the construction site are detected to be consistent with the components in the BIM finished model, it is judged that the component has been completed. The components that have been completed under the current construction progress are scanned at fixed intervals T. Let the number of components that have been completed be k, then the data volume of the BIM model is ∑S k , the complexity of the BIM model is ∑R k The data volume and structural complexity analysis index of the BIM finished model is X = μ∑S i +δR, the construction progress index of the current BIM model is Where μ is the weight coefficient of data volume to analysis volume index, δ is the weight coefficient of structural complexity to analysis volume index, α is the weight coefficient of data volume to construction progress, β is the weight coefficient of structural complexity to construction progress, and α+β=1.

[0017] According to the above technical solution, in S3, the specific method for determining the analysis mode adopted by the BIM model under the current progress is:

[0018] S3-2. First, according to the size of the BIM finished model analysis index X, it is determined whether a single analysis mode or a combination of two analysis modes is used. When X≤X0, it is judged that the data volume of the BIM finished model is small and the structural complexity is low. When comparing and analyzing, only the mode of directly comparing and analyzing with the BIM model is used. When X>X0, it is judged that the data volume of the BIM finished model is large and the structural complexity is high. When comparing and analyzing, the analysis mode of comparing the latest data with the previous data is used in the early stage, and the mode of directly comparing and analyzing with the BIM model is used in the later stage.

[0019] S3-3. The construction progress index needs to be judged only when X>X0. When the construction progress index of the current BIM model is Y×100%≥a%, the construction is judged to be in the later stage, and a mode of direct comparison and analysis with the BIM model is adopted. When the construction progress index of the current BIM model is Y×100%<a%, the construction is judged to be in the early stage, and an analysis mode of comparing the latest data with the previous data is adopted.

[0020] According to the above technical solution, in S4, the method for determining the inherent properties of the components in the BIM model is:

[0021] S4-1. The analysis quantity index of a component in the BIM finished model and the space occupied by the component itself S i and the structural complexity R of the component itself i Related, specifically the component analysis index Z = μS i +δR i ;

[0022] The specific method for setting the frequency of participating in the comparison analysis is:

[0023] S4-2. The more complex the component, the lower the frequency of comparison and analysis. Since the entire BIM model is scanned at a fixed period T, the component is scanned at nT periods, and nT = τZ, where τ is the conversion factor between the component's analysis quantity index and the scanning interval period.

[0024] According to the above technical solution, in S2, when a damaged component is found, the component is adjusted from a constructed state to an unconstructed state, and is removed from the current BIM model until the component conforms to the corresponding component in the BIM finished model again.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention analyzes and sorts the data volume and structural complexity of each BIM model on the construction site; for BIM models with large data volume and high structural complexity, an analysis mode of comparing the latest data with previous data is more inclined to be adopted in the early stage of information collection; and a mode of directly comparing and analyzing with the BIM model is more inclined to be adopted in the later stage; for BIM models with small data volume and low structural complexity, a mode of directly comparing and analyzing with the BIM model is more inclined to be adopted; at the same time, the frequency of participating in the comparison and analysis is determined according to the properties of the components within the BIM model, so as to achieve a balance between analysis accuracy and analysis speed.
