Description

Technical Field

[0001] This invention relates to the field of interior design technology, and more specifically to a visual collaborative platform and method based on interior design. Background Technology

[0002] As the building decoration industry gradually develops towards digitalization and intelligence, interior design and construction are also gradually transforming from traditional manual management to information-based and collaborative approaches. Interior decoration projects involve multiple aspects such as space planning, material selection, multi-process cross-construction, and on-site environmental management. Traditional interior design and construction models still have many problems. Therefore, it is crucial to develop a visual collaborative method based on interior design.

[0003] There are still some shortcomings in the visualization and collaboration of existing interior design, which are reflected in the following aspects: (1) In the existing technology, the design information and the actual construction information are disconnected. Interior design is mainly based on two-dimensional drawings and three-dimensional renderings. It is difficult to achieve real-time linkage between design results and on-site construction procedures, material usage and process nodes. There are a lot of information errors between the designer, the construction party and the management party, and their information perception cannot achieve uniformity in the time dimension.

[0004] (2) Existing construction methods are all arranged according to the contractor's experience sequence, without taking into account the material pollution generation coefficient, construction time, on-site ventilation, temperature and humidity, light and other environmental conditions to quantitatively analyze pollution release. This can easily lead to the instantaneous concentration of pollutants exceeding the standard during construction, endangering the health of construction workers, and resulting in large amounts of residual indoor pollutants and long purification cycles after completion. At the same time, the visualization of the construction process and pollution status is insufficient and lacks a dynamic update mechanism. Existing indoor design platforms focus too much on the basic display of progress, cost and quality, and lack an integrated and visualized presentation of information such as construction process breakdown, pollution level, environmental parameters, concentration changes, and safety thresholds. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the present invention aims to provide a visual collaborative platform and method based on interior design.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The first aspect of the present invention provides a visual collaborative method based on interior design, including: S1, breaking down each construction process based on interior design information and predicting the pollution information corresponding to each construction process.

[0007] S2. Obtain environmental information within a preset time period.

[0008] S3. Based on the various processes of interior design, the pollution information corresponding to each process, and the environmental information within the preset time period, analyze the construction sequence corresponding to each process within the preset time period.

[0009] S4. Build a visualization platform to display interior construction design information and determine whether to update the construction sequence.

[0010] A second aspect of the present invention provides a visual collaborative platform based on interior design, comprising: a process decomposition module: used to decompose each construction process based on interior design information and predict pollution information corresponding to each construction process.

[0011] Environmental information acquisition module: used to acquire environmental information within a preset time period.

[0012] Construction sequence prediction module: This module is used to analyze the optimal construction sequence for each process within a preset time period based on the various processes of interior design, the pollution information corresponding to each process, and the environmental information within a preset time period.

[0013] Visualization module: Used to build a visualization platform to display interior construction design information and determine whether to update the construction sequence.

[0014] The beneficial effects of this invention are as follows: By decomposing interior design information, this invention realizes the transformation of design data into construction procedures, and the deep integration and coordination of interior design information with actual construction, solving the problems of design and construction disconnect, untimely information transmission, and low coordination efficiency. Simultaneously, based on constraints, it predicts the specific construction sequence of each construction procedure, ensuring the safety of on-site construction personnel and minimizing residual indoor pollution after completion. Furthermore, through the linkage of two-dimensional views and three-dimensional BIM models, it provides an integrated and visualized presentation of spatial structure, procedure decomposition, construction progress, pollution information, and environmental information, supporting real-time viewing, filtering, positioning, and interaction, making the construction process transparent and management intuitive.

Obviously, the drawings described below are only some embodiments of the present invention.

[0017] Figure 2 This is a schematic diagram of the platform structure connection of the present invention. Detailed Implementation

[0018] 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, and 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.

[0019] Reference Figure 1 As shown, the present invention provides a visual collaboration method based on interior design, including: S1, breaking down each construction process based on interior design information and predicting the pollution information corresponding to each construction process.

[0020] It should be noted that pollutants generated during indoor construction mainly include VOCs, formaldehyde, benzene compounds, and particulate matter such as dust.

[0021] In a specific example, the process of breaking down each construction process based on interior design information and predicting the pollution information corresponding to each construction process is as follows: obtaining interior design information from the design center, which includes interior space information, material information, and construction specification information.

[0022] It should be noted that the spatial information includes the interior functional zoning (living room, bedroom, kitchen, bathroom, etc.), the dimensions of each space, the distribution of walls (load-bearing / non-load-bearing walls), and the location of doors and windows; the material information includes the decoration materials for each interior functional zone (such as wall materials: latex paint, wallpaper, diatomaceous earth; floor materials: tiles, wood flooring, stone; ceiling materials: gypsum board, aluminum composite panels; water and electricity materials: pipes, wires, waterproof coatings, etc.), material specifications, and usage.

[0023] First, based on the indoor space information and construction specifications, each primary process is decomposed. Then, the next construction step corresponding to each primary process is recorded as the secondary process of each primary process. The above steps are repeated until the decomposition of each level of process is completed.

[0024] It should be noted that when a certain level of process corresponds to more than one next construction process, that level of process corresponds to multiple level-two processes.

[0025] It should be noted that each first-level process includes water and electricity renovation, wall construction, floor construction, and ceiling construction.

[0026] For example, when the first-level process is the wall construction process, the second-level process is the wall finishing process, and the third-level process is the wall base treatment. The wall base treatment includes removing plaster, sanding, and applying putty, etc.; the wall finishing process includes applying stripes or tiles to the wall after the base treatment is completed.

[0027] Query the pollution generation coefficients of the materials used in each construction process, and combine the pollution generation coefficients of the materials used in each construction process with the construction time to record the pollution information.

[0028] It should be noted that the pollution generation coefficients of the materials used in each construction process can be found in the 2021 edition of the "Pollution Generation and Discharge Coefficient Handbook". For example, the pollution generation coefficient of cement dust is 120 kg / ton; and the VOC pollution generation coefficient of solvent-based coatings is 0.3 kg / L, etc.

[0029] It should be noted that the construction duration is determined by the construction unit based on the interior design information, and no specific limit is set here.

[0030] S2. Obtain environmental information within a preset time period.

[0031] In a specific example, the environmental information includes ventilation information, lighting information, and indoor temperature and humidity, wherein the ventilation information includes the ventilation duration and air circulation rate during daily indoor construction; and the lighting information includes the lighting duration and illuminated area of ​​the construction area during daily indoor construction.

[0032] It should be noted that the ventilation duration during daily construction is obtained from the construction unit and is generally equal to the daily construction duration; the indoor temperature and humidity are set to be the same as the outdoor temperature and humidity; at the same time, light and wind information for a preset time period is obtained from the meteorological department, and the indoor environment is simulated based on the light and wind information for the preset time period, so as to obtain the daily indoor air circulation rate, light duration and light area of ​​the construction area. The light information includes light duration and light intensity, and the wind information includes wind speed and wind direction.

[0033] It should be noted that the preset time period is the longest time period corresponding to the light and wind information that the meteorological department can query.

[0034] S3. Based on the construction procedures of the interior design, the pollution information corresponding to each construction procedure, and the environmental information within the preset time period, analyze the optimal construction sequence for each construction procedure within the preset time period.

[0035] In a specific example, the process of analyzing the optimal construction sequence for each construction procedure within a preset time period based on the construction procedures of the interior design, the pollution information corresponding to each construction procedure, and the environmental information within a preset time period is as follows: input each construction procedure, the pollution information corresponding to each construction procedure, and the environmental information within a preset time period into a pre-trained construction sequence decision model, and output the optimal construction sequence for each construction procedure within a preset time period through the construction sequence decision model.

[0036] In a specific example, the constraints of the construction sequence decision model are that the instantaneous concentration of pollutants during construction is less than a set concentration threshold and the indoor pollutant residue is minimized after construction is completed.

[0037] It should be noted that the set concentration thresholds were obtained by consulting relevant technical documents. For example, the Occupational Exposure Limits for Hazardous Factors in the Workplace (GBZ2.1) and the Code for Indoor Environmental Pollution Control of Civil Building Engineering (GB50325) stipulate that the PC-TWA threshold for VOCs at an 8-hour time weighted average concentration is 500 mg / m³. 3 The formaldehyde PC-STEL threshold is 0.1 mg / m³. 3 .

[0038] In a specific example, the training process of the construction sequence decision model is as follows: First, the data set of the construction sequence decision model is obtained by simulation. The data set is divided into a training set and an optimization set according to a preset ratio. Then, the text features, sequence features and numerical features in the data set are encoded, quantized, mapped, and normalized respectively.

[0039] LightGBM was used as the core prediction model, and a constraint judgment layer was embedded at the model output to obtain the basic architecture of the construction sequence decision model. The constraint judgment layer includes constraints on the instantaneous concentration of pollutants and constraints on the amount of indoor pollutants remaining after construction.

[0040] It should be noted that the instantaneous concentration constraint for pollutants is: Where W represents the amount of materials used in the process, k represents the pollution generation coefficient, v represents the pollutant volatilization rate, Q represents the ventilation volume (air circulation rate × indoor space volume), and t represents the construction time of the process; the indoor pollutant residue after construction is constrained to be... Where i is the process number and n is the total number of processes. and These represent the total ventilation volume and the total concentration of volatile pollutants during the construction period. and These represent the material consumption and pollution coefficient of the i-th process, respectively. This represents the construction time of the i-th process.

[0041] The infrastructure of the construction sequence decision model is trained and optimized using training and optimization sets, and then the construction sequence decision model is output.

[0042] It should be noted that the dataset is divided into a training set and an optimization set in a 7:3 ratio. During the training and optimization of the construction sequence decision model's infrastructure using the training and optimization sets, a weighted multi-objective loss function is employed: Loss = 0.7 * safety index feature value + 0.3 * residual index feature value. The safety index feature value represents the penalty loss (e.g., mean squared error, MSE) for samples with instantaneous concentration exceeding the standard; the residual index feature value represents the mean squared error between the predicted residual amount and the actual optimal residual amount.

[0043] It should also be noted that the core parameters of the model (such as the learning rate of LightGBM) are tuned through grid search or Bayesian optimization algorithms. The constraint satisfaction rate and pollution residue reduction rate of the validation set are used as evaluation indicators. When the constraint satisfaction rate of the validation set is <95%, the dataset is supplemented by simulation and retraining is performed. When the residue reduction rate is <10%, the weights of the loss function are adjusted until the model meets the following conditions: constraint satisfaction rate ≥98% and residue reduction rate ≥15%.

[0044] After the construction sequence decision model is trained, the model is encapsulated as an API interface and connected to the constructed visualization platform.

[0045] In a specific example, the simulation obtains a data set for the construction sequence decision model. The specific process is as follows: retrieve design information of historical interior design projects of the same type from the data center, break down each construction process, and then retrieve the material usage, environmental information, construction sequence, instantaneous concentration monitoring value of pollutants, and residual concentration value of pollutants after construction for each construction process.

[0046] After preprocessing the construction procedures, material usage, environmental information, construction sequence, instantaneous pollutant concentration monitoring values, and post-construction pollutant residual concentration values ​​of various historical similar interior design projects, an indoor environmental simulation software was used to simulate the construction process of these projects. The construction sequence of each procedure was changed to obtain the instantaneous pollutant concentration monitoring values ​​and post-construction pollutant residual concentration values ​​for historical similar interior design projects with the same construction procedures, material usage, and environmental information but different construction sequences. Thus, the construction procedures, material usage, environmental information, construction sequence, and the corresponding instantaneous pollutant concentration monitoring values ​​and post-construction pollutant residual concentration values ​​for these historical similar interior design projects were comprehensively recorded as the data set for the construction sequence decision model.

[0047] It should be noted that preprocessing includes outlier removal, missing value completion, and data standardization. Outlier removal, missing value completion, and data standardization are all existing technologies and will not be elaborated on here.

[0048] S4. Build a visualization platform to display interior construction design information and determine whether to update the construction sequence.

[0049] In a specific example, the visualization platform is used to display interior construction design information. The specific process is as follows: The visualization platform uses a combination of two-dimensional planar views and three-dimensional spatial views to realize the visualization of the interior space structure.

[0050] A tree diagram is used to visualize the breakdown of construction procedures.

[0051] Trend charts are used to visualize changes in environmental and pollution information.

[0052] Visualize the optimal construction sequence using Gantt charts.

[0053] It should be noted that the visualization platform obtains spatial structure data by parsing the interior design CAD / BIM model, and binds construction procedures, pollution information, environmental information, construction sequence and interior space coordinates; then it renders a two-dimensional plan view based on Canvas / SVG, and builds a three-dimensional spatial view based on Three.js. The two-dimensional and three-dimensional views are linked in real time. Through layer control, the platform realizes the integrated display of interior space structure, construction procedures, construction sequence, pollution information and environmental information, and supports selecting areas to view corresponding detailed information.

[0054] The decomposed construction procedures are processed into a hierarchical tree structure in JSON format, and attributes such as construction location and materials are added to each construction procedure node. The tree diagram is rendered based on a visualization chart component, which supports node collapsing / expanding, hovering to view details, and filtering by conditions, so as to realize the visualization display of the construction procedure decomposition.

[0055] It collects environmental and pollution information from the construction site in real time and processes it in a structured manner according to the timeline; it renders trend curves based on line graph components, displays the safety threshold of pollutants with red dashed lines, highlights periods exceeding the standard in red, supports timeline scaling, multi-dimensional curve switching and overlay, and realizes a visual display of changes in environmental and pollution information.

[0056] Simultaneously, the optimal construction sequence output by the construction sequence decision model is structured into a "process-time-region-pollution level" format; the construction sequence is rendered based on the Gantt chart component, with the X-axis as the time axis and the Y-axis as the process name. The task bar is colored according to the pollution information, and the corresponding environmental information is displayed when hovering. Process filtering, time adjustment, and result export are supported to achieve a visual display of the optimal construction sequence.

[0057] In a specific example, the process of determining whether to update the construction sequence is as follows: After any construction process is completed, taking the end time of that process as the starting time point, environmental information within a preset time period is obtained. The uncompleted construction processes, the pollution information corresponding to each construction process, and the environmental information within the preset time period are input into a pre-trained construction sequence decision model. The construction sequence decision model outputs the optimal construction sequence corresponding to each construction process within the preset time period. The output optimal construction sequence is compared with the original optimal construction sequence. If they are the same, the construction sequence is not updated; otherwise, the output optimal construction sequence is updated to the optimal construction sequence.

[0058] It should be noted that during the construction process, the optimal construction sequence of the remaining procedures can be re-determined based on the completed procedures and real-time environmental information, realizing dynamic iteration and adaptive optimization of the construction plan, improving the adaptability to changes in on-site working conditions, weather fluctuations, and deviations in construction progress, and ensuring the continuous achievement of environmental protection and safety goals throughout the entire process.

[0059] It should also be noted that the construction sequence analyzed in this invention refers to the construction sequence between construction procedures of the same level. For the construction sequence between construction procedures of different levels, the construction sequence of the lower-level construction procedure must take precedence over the construction sequence of the higher-level construction procedure. For example, the construction sequence of the third-level construction procedure is greater than the construction sequence of the second-level construction procedure and then the construction sequence of the first-level construction procedure.

[0060] Reference Figure 2 As shown, the present invention provides a visual collaborative platform based on interior design, including: a process decomposition module: used to decompose each construction process based on interior design information and predict the pollution information corresponding to each construction process.

[0061] Environmental information acquisition module: used to acquire environmental information within a preset time period.

[0062] Construction sequence prediction module: This module is used to analyze the optimal construction sequence for each process within a preset time period based on the various processes of interior design, the pollution information corresponding to each process, and the environmental information within a preset time period.

[0063] Visualization module: Used to build a visualization platform to display interior construction design information and determine whether to update the construction sequence.

[0064] It should be noted that during indoor construction, the concentration of pollutants emitted by construction materials varies under different ventilation and lighting conditions, which also affects the residual indoor pollution after the construction is completed. Due to the limitations of the construction environment (the inability to use fans or other means to accelerate air circulation, which may aggravate indoor dust pollution), existing technologies do not have suitable means to control pollutants and reduce the safety risks for construction workers during indoor construction. This invention adjusts the construction sequence based on environmental information, allowing for the construction of processes with more severe pollutant volatilization when the air circulation rate is high. This greatly reduces indoor pollution residue while ensuring the safety of construction workers.

[0065] This invention first breaks down each construction process based on interior design information and predicts the pollution information corresponding to each construction process to obtain environmental information within a preset time period. Based on each construction process in the interior design, the pollution information corresponding to each construction process, and the environmental information within the preset time period, it analyzes the optimal construction sequence for each construction process within the preset time period. This realizes the transformation of design data into construction processes, and achieves deep integration and coordination between interior design information and actual construction. It solves the problems of design and construction disconnect, untimely information transmission, and low coordination efficiency. At the same time, through the linkage of two-dimensional views and three-dimensional BIM models, it provides an integrated and visual presentation of spatial structure, process breakdown, and construction sequence, making the construction process transparent and management intuitive.
