[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0057] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0058] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0059] See also Figure 1 As shown, the present invention provides a BIM-based interior decoration planning method, comprising:

[0060] S1. Acquire three-dimensional model data of interior space decoration and record it as reference data, wherein the reference data includes size information and color information;

[0061] S2. Create corresponding decorative elements in the three-dimensional model of the interior space according to the filling requirements of the benchmark data, and perform simulated layout;

[0062] S3. Determine the construction process according to the location information of the decorative elements, collect the construction progress in real time, and generate a construction progress report;

[0063] S4. Evaluate the decoration status of each construction process according to the construction progress report, wherein the decoration status includes a normal state and an abnormal state;

[0064] Under normal conditions, it indicates that the construction progress of the corresponding construction process is normal, and the completion time node of the corresponding construction process is predicted simultaneously;

[0065] Under abnormal conditions, it indicates that the construction progress of the corresponding construction process is delayed, and the progress delay amount is output synchronously, and then the construction plan is adjusted according to the progress delay amount.

[0066] As described in the above steps S1-S4, as people's demand for interior decoration continues to increase, the demand for decoration drawings is more stringent, but often the same drawing requires multiple people to operate, and communication is also required through the two-dimensional drawing, and the real interior layout cannot be perceived. In this embodiment, it is first necessary to obtain the three-dimensional model data of the interior space decoration and record it as benchmark data. The benchmark data not only includes size information, but also covers color information, providing a detailed reference basis for subsequent decoration planning. Next, according to the filling requirements in the benchmark data, corresponding decorative elements are created in the three-dimensional model of the interior space. The decorative elements can be walls, floors, etc., and the decorative elements are placed in appropriate positions in the three-dimensional model through simulated layout to achieve the best visual effects and functional requirements. After the layout of the decorative elements is completed, the specific construction process is determined according to the location information of the decorative elements. To ensure the smooth progress of the construction, during the construction process In the process, construction progress information will be collected in real time and a construction progress report will be generated. The construction progress report will record the completion status of each construction stage and provide real-time progress feedback to project managers. Based on the construction progress report, the decoration status of each construction process can be evaluated. The decoration status can be divided into normal status and abnormal status. In the normal status, it indicates that the construction progress of the corresponding construction process is in line with expectations and the project is progressing smoothly. At this time, the completion time node of the corresponding construction process can be predicted synchronously to provide a reference for subsequent work arrangements. However, in the abnormal status, it indicates that the construction progress of the corresponding construction process is lagging behind and has failed to achieve the expected goal. At this time, it is necessary to synchronously output the progress lag, analyze the reasons for the lag, and adjust the construction plan based on the progress lag. In this way, the construction delay can be corrected in time to ensure that the project can be completed on schedule, ensure the consistency of the decoration effect with the original design intention, and better control the construction progress and cost.

[0067] In a preferred embodiment, when acquiring the three-dimensional model data of the interior space decoration, a laser scanner is used to measure the size information of the interior space decoration, and a high-definition camera is used to capture the color information of the interior space decoration, and the size information and color information of the interior space decoration are summarized as benchmark data.

[0068] In this embodiment, in the process of obtaining the three-dimensional model data of the interior space decoration, the corresponding laser scanner is first used to accurately measure the interior space to obtain its size information. The laser scanner can quickly and accurately capture every corner and detail of the interior space, thereby ensuring the accuracy of the size information. At the same time, a high-definition camera is used to photograph the interior space decoration to capture its rich color information. The high-definition camera can capture subtle color differences and layers to ensure the authenticity and delicacy of the color information. The size information obtained by the laser scanner and the color information captured by the high-definition camera are then integrated through professional data processing software to ensure that the size information and color information can be seamlessly connected to form a complete three-dimensional model data of the interior space decoration, providing reliable benchmark data for subsequent design, modification and construction.

[0069] In a preferred embodiment, according to the filling requirements of the reference data, the steps of creating corresponding decorative elements in the three-dimensional model of the indoor space and performing a simulated layout include:

[0070] S201, obtaining decoration style and material information required by the user;

[0071] S202, applying the decoration style and material information to the three-dimensional model of the interior space based on BIM to form decorative elements with decorative effects;

[0072] S203, laying out the decorative elements in the three-dimensional model of the interior space to simulate the actual decorative layout;

[0073] If the decorative element cannot be filled in the three-dimensional model of the interior space, the size of the decorative element is adjusted until the decorative element fits the three-dimensional model of the interior space. Otherwise, the next decorative element that needs to be filled is continued to be filled.

[0074] As described in the above steps S201-S203, in order to meet the user's decoration needs in the interior space design, it is necessary to create and layout the corresponding decoration elements in the three-dimensional model. First, it is necessary to obtain the user's specific needs in detail, including the desired decoration style and the selected material information, and use BIM (Building Information Modeling) technology to apply the decoration style and material information selected by the user to the three-dimensional model of the interior space, so that decorative elements with specific decorative effects can be created. The decorative elements will be accurately integrated into the three-dimensional model, making the entire design process more intuitive and efficient. After creating the decorative elements, it is necessary to layout these elements in the three-dimensional model of the interior space. The purpose of the simulated layout is to In order to ensure that the effect of decorative elements in the actual space can meet the expectations, and at the same time, it is convenient for users to intuitively see the final effect in the early stage of design, if it is found during the layout process that some decorative elements cannot adapt to the three-dimensional model of the interior space, that is, they cannot be smoothly filled into the specified position, the sizes of these decorative elements will be adjusted. The adjustment process will continue until all decorative elements can perfectly adapt to the three-dimensional model of the interior space. On the contrary, if the decorative elements can be smoothly filled into the interior space, the next decorative element to be filled will continue to be laid out and adjusted according to user needs to ensure that the layout of decorative elements in the three-dimensional model of the interior space meets both the user's aesthetic needs and the constraints of the actual space.

[0075] In a preferred embodiment, the step of evaluating the decoration status of each construction process according to the construction progress report includes:

[0076] S401, collecting the construction progress of the corresponding construction process from the construction progress report;

[0077] S402, obtaining a preset standard progress, and comparing the standard progress with the construction progress;

[0078] If the construction progress lags behind the standard progress, the decoration status of the corresponding construction process will be recorded as an abnormal state, and an alarm signal will be issued simultaneously;

[0079] If the construction progress is equal to or ahead of the standard progress, the decoration status of the corresponding construction process will be recorded as normal.

[0080] As described in the above steps S401-S402, in order to evaluate the decoration status of each construction process, it is first necessary to carefully collect the construction progress data corresponding to each construction process and the pre-set standard progress data from the construction progress report. The standard progress data is pre-set according to the project plan and construction plan, and is used as a benchmark for evaluating the construction progress. The standard progress data is then compared with the construction progress collected from the construction progress report. During the comparison process, if it is found that the construction progress is obviously behind the preset standard progress, action will be taken immediately. Specifically, the decoration status of the corresponding construction process will be recorded as an abnormal state, and an alarm signal will be issued simultaneously. The alarm signal is issued to promptly notify project management personnel and related teams so that they can take quick measures to solve the problem of lagging construction progress and ensure that the project can be completed on time. On the contrary, if it is found through comparison that the construction progress is equal to or ahead of the standard progress, the decoration status of the corresponding construction process will be recorded as a normal state, which means that the construction progress is in line with expectations, the project is progressing smoothly, and no additional intervention measures are required.

[0081] In a preferred embodiment, after the abnormal state is output, an evaluation period is constructed with the node where the abnormal state occurs as the starting point;

[0082] Set multiple evaluation nodes within the evaluation period, and collect the construction progress of the corresponding construction process under each evaluation node;

[0083] If the construction progress of the corresponding construction process at each evaluation node is lagging behind, the decoration status of the construction process will be immediately anchored as abnormal;

[0084] If there is a construction progress in the evaluation node that is equal to or ahead of the standard progress, it indicates that the abnormal state of the corresponding construction process is a transient phenomenon, and the abnormal state is converted to a normal state.

[0085] In this embodiment, after the abnormal state is detected, it is necessary to construct an evaluation period with the specific node where the abnormal state occurs as the starting point. During the evaluation period, multiple evaluation nodes will be set so that we can collect and record in detail the construction progress of each construction process under the evaluation node. Specifically, the construction process under each evaluation node will be tracked in detail to ensure that the specific situation of the construction progress can be accurately understood. If it is found that the progress of each construction process lags behind the predetermined planned progress at the evaluation node, then the decoration status of these construction processes will be immediately determined to be an abnormal state. However, if it is found that the progress of some construction processes is equal to or exceeds the standard progress in the evaluation node, then it indicates that the abnormal state of the corresponding construction process is only temporary, rather than a persistent problem. In this case, the previously marked abnormal state will be converted to a normal state to reflect the actual progress of the construction process, which will help to more accurately evaluate and manage various states in the construction process and ensure the smooth progress of the construction project.

[0086] In a preferred embodiment, the step of predicting the completion time node of the corresponding construction process includes:

[0087] Obtain the amount of advanced completion of the corresponding construction process under normal conditions and record it as a prediction condition parameter;

[0088] Obtain a prediction function, input the prediction condition parameters into the prediction function, and record the output result of the prediction function as the predicted demand duration;

[0089] Based on the predicted demand duration, the current time node is offset, and the offset result is recorded as the predicted completion time node of the construction process.

[0090] In this implementation, in order to accurately predict the completion time node of the construction process, it is first necessary to obtain the advance completion amount of the corresponding construction process under normal conditions. The advance completion amount refers to the part of the construction process that has been completed without any delays and unexpected situations. The advance completion amount is recorded and used as a prediction condition parameter. Secondly, a prediction function needs to be obtained, and the completion time of the construction process is predicted based on the input prediction condition parameters, where the expression of the prediction function is: , where Indicates the predicted demand duration, Indicates the total amount of construction, Indicates the required construction volume at the current node. represents the prediction condition parameter, Indicates the number of statistics of the amount completed ahead of time. It represents the construction speed at the current node. The prediction function is run to get the output result, and then the predicted demand time is determined. Finally, the current time node needs to be offset according to the predicted demand time, that is, the current time node is pushed back by the predicted demand time to get the predicted completion time node of the construction process.

[0091] In a preferred embodiment, the step of outputting the progress lag includes:

[0092] Obtain the duration of the abnormal state, and set multiple parallel nodes within the duration;

[0093] Collect the progress delay of the corresponding construction process at each parallel node and record it as the evaluation condition parameter;

[0094] Obtain a calculation function, input the evaluation condition parameters into the calculation function, and record the output result of the calculation function as the progress lag.

[0095] In this implementation, in order to describe the output progress lag in detail, first, it is necessary to obtain the duration of the abnormal state, which specifically involves continuous monitoring and recording of abnormal situations occurring in the project to determine the time points when the abnormal state starts and ends. After determining the duration of the abnormal state, it is necessary to set multiple parallel nodes within the duration, and the time period between adjacent parallel nodes can be one day, one week, etc., and then it is necessary to collect the progress lag of the corresponding construction process under each parallel node, determine the gap between the construction progress and the planned progress under each parallel node, and record it as an evaluation condition parameter for subsequent analysis and calculation, and then introduce a preset measurement function, the expression of the measurement function is: , where Indicates the progress lag, represents the number of parallel nodes, It represents the evaluation condition parameters under each parallel node, calculates the progress lag according to the input evaluation condition parameters, inputs the evaluation condition parameters under each parallel node into the measurement function, and obtains the output result through the calculation process of the measurement function. The output result will be recorded as the specific progress lag, thereby providing corresponding reference basis for project management and decision-making.

[0096] In a preferred embodiment, the step of adjusting the construction plan according to the progress delay includes:

[0097] Get the progress lag;

[0098] Obtain the allowable adjustment amount between adjacent parallel nodes;

[0099] A planning function is obtained, and the progress lag and the allowable adjustment amount are input into the planning function together, and the output result of the planning function is recorded as the demand control period.

[0100] In this implementation, in order to adjust the construction plan according to the specific progress lag, it is necessary to first obtain the current progress lag, and then obtain the allowable adjustment amount between adjacent parallel nodes. In the construction plan, adjacent parallel nodes usually refer to those construction activities that can be carried out simultaneously or need to be coordinated, so as to determine the maximum adjustment range that can be made without affecting the overall progress. Next, it is necessary to obtain the preset planning function, where the expression of the planning function is: , where Indicates the demand regulation period, Indicates the allowable adjustment amount, It represents the duration between parallel nodes. The progress lag and the allowable adjustment are used as input parameters and input into the planning function. The output of the planning function is recorded as the demand control period. During this period, the construction team needs to work according to the new plan to ensure that the project can be completed on time and minimize the impact of progress lag.

[0101] See also Figure 2 , a BIM-based interior decoration planning method, using the above BIM-based interior decoration planning method, including:

[0102] A data acquisition module, the data acquisition module is used to acquire the three-dimensional model data of the interior space decoration and record it as reference data, wherein the reference data includes size information and color information;

[0103] The simulation module is used to create corresponding decorative elements in the three-dimensional model of the interior space and perform simulated layout according to the filling requirements of the benchmark data;

[0104] Monitoring module, which is used to determine the construction process according to the location information of the decorative elements, collect the construction progress in real time, and generate a construction progress report;

[0105] A status evaluation module is used to evaluate the decoration status of each construction process according to the construction progress report, wherein the decoration status includes a normal status and an abnormal status;

[0106] Under normal conditions, it indicates that the construction progress of the corresponding construction process is normal, and the completion time node of the corresponding construction process is predicted simultaneously;

[0107] Under abnormal conditions, it indicates that the construction progress of the corresponding construction process is delayed, and the progress delay amount is output synchronously, and then the construction plan is adjusted according to the progress delay amount.

[0108] In the above, the system includes a data acquisition module, a simulation module, a monitoring module and a status evaluation module. The data acquisition module is responsible for collecting the three-dimensional model data required for interior space decoration and recording these data as benchmark data. The benchmark data not only includes the size information of the interior space, but also covers the color information, providing an accurate reference basis for subsequent decoration design. After acquiring the benchmark data, the simulation module creates corresponding decorative elements in the three-dimensional model of the interior space according to the filling requirements in the benchmark data. The decorative elements can be furniture, lamps, decorations, floors and walls, etc. The main function of the simulation module is to simulate the layout of decorative elements. Through BIM technology, designers can intuitively see the placement effect of decorative elements in three-dimensional space, so as to optimize and adjust them to ensure that the final decorative effect meets the design requirements. The monitoring module is responsible for real-time monitoring of the construction process of decorative elements, determining the construction process according to the location information of the decorative elements, and collecting the construction progress in real time. Through the monitoring module, the project manager can generate a construction progress report to keep abreast of the progress of the project. The construction progress report not only helps the project manager to grasp the construction progress, but also serves as an important basis for subsequent evaluation and adjustment of the construction plan. The status evaluation module evaluates the decoration status of each construction process based on the construction progress report. The decoration status can be divided into normal status and abnormal status. In the normal status, it indicates that the construction progress of the corresponding construction process is in line with expectations. The project manager can simultaneously predict the completion time node of the corresponding construction process to ensure that the project proceeds as planned. In the abnormal status, it indicates that the construction progress of the corresponding construction process is lagging behind. At this time, the status assessment module will synchronously output the progress lag and adjust the construction plan according to this lag, in order to restore the normal construction progress as soon as possible and reduce the losses caused by project delays.
