Description

Technical Field

[0001] The present invention relates to the technical field of engineering project management, and in particular to an automatic engineering progress measurement system based on BIM technology. Background Art

[0002] With the development and construction of cities, the construction industry has also been fully developed. Since construction projects have long cycles, high construction difficulty, and involve many people, there are many issues of progress monitoring and cost control in the process of construction projects. Therefore, in order to ensure the normal and smooth progress of construction projects, it is necessary to monitor the progress of construction projects;

[0003] The existing engineering project management system cannot be intelligently associated with the progress engineering structure, and it is difficult to intuitively display the engineering progress, making it difficult to directly judge the difference between the current engineering progress and the expected engineering progress. In addition, the existing engineering project management system cannot directly and automatically calculate the remaining engineering cycle and automatically measure, which will affect the management efficiency of the engineering progress. For this reason, we propose an automatic engineering progress measurement system based on BIM technology. Summary of the invention

[0007] The engineering data acquisition module collects historical engineering data through various means, processes the data, and transmits the processed data to the database module;

[0008] A database module is used to establish a database, which can receive and store data transmitted by the engineering data acquisition module and transmit the data to the model training module;

[0009] The BIM model building module is used to create the BIM model and improve the BIM model structure according to the project requirements and characteristics until the BIM model can accurately reflect the actual situation of the project.

The BIM model training unit is used to receive data transmitted by the database module and use the historical data in the database module to train and verify the BIM model, so as to improve the prediction accuracy of the BIM model. The BIM model storage unit is used to store the BIM model that meets the training requirements.

[0011] The project information input module is used to input the current project information and transmit the project information to the progress display module and the project entity structure association module;

[0012] The progress display module is used to receive the current project information transmitted by the project information input module, and can interact with the BIM model in the BIM model storage unit in real time, use the current project information to associate with the BIM model, simulate the current project through the BIM model and the current project information, and transmit the simulation data to the progress comparison module, which can intuitively display the project progress through the display screen in different forms of color;

[0013] The progress comparison module is used to provide an interactive interface to help managers input the current construction progress, compare the current construction progress with the drill progress in the progress display module, and display the difference between the actual progress and the predicted progress in different forms, and transmit the comparison data to the engineering entity structure association module;

[0014] The engineering entity structure association module associates the model training module with the engineering entity structure to achieve automatic measurement and judgment of construction progress and output value, thereby improving engineering management efficiency.

[0015] As a further solution of the present invention: the engineering data acquisition module collects information on multiple past completed projects through a project management system, construction log, progress plan report, acceptance report and construction contract. The engineering information includes construction period, project volume, staffing, construction progress, building structure, construction time and construction material information, and cleans, organizes and converts the acquired engineering information into a format that can match the model training module.

[0016] As a further solution of the present invention: the database module is inserted with an information encryption unit and an information editing unit. The information encryption unit uses a PSA encryption algorithm to ensure the data security of the engineering information in the database during transmission and storage. The information editing unit can provide an information editing window to facilitate manual modification of abnormal data and ensure the accuracy of the engineering data.

[0017] As a further solution of the present invention: the BIM model building module is provided with deep network learning technology, and uses Unreal Engine to create a BIM model based on the scale, volume, function and design requirements of the current engineering project.

[0018] As a further solution of the present invention: the BIM model training unit in the model training module is provided with a convolutional neural network technology, the BIM model training unit can receive the data processed by the database module, and divide the processed data set into a training set and a test set, the ratio of the training set to the test set is 7:3, the BIM model is trained by the training set through the convolutional neural network technology, the BIM model is trained by a large amount of data to adjust its own parameters, so as to accurately predict new data, the trained BIM model is verified by the test set, the accuracy of the model is verified by inputting the test set into the BIM model, the generalization ability and accuracy of the BIM model are tested by evaluating the performance of the model on the data, until the calculation accuracy of the BIM model reaches more than 98%, and then the hyperparameters of the BIM model are tuned according to the performance results of the model to further improve the performance and generalization ability of the BIM model, and then the trained model is stored in the BIM model storage unit.

[0019] As a further solution of the present invention: the engineering information input module includes construction period, engineering volume, staffing situation, construction progress, building structure, construction time and construction material information, and uses Bentley MicroStation to convert the input information into a format that can be recognized by the BIM model.

[0020] As a further solution of the present invention: the progress display module can transmit the input engineering information data to the BIM model, and the BIM model analyzes the time of each construction process according to the input engineering information. The construction process includes foundation treatment, main structure construction, exterior wall construction, roof construction, indoor partition wall, floor paving, ceiling construction, interior decoration, electrical equipment installation, water heating equipment installation, air conditioning equipment installation and system debugging. The construction times of foundation treatment, main structure construction, exterior wall construction, roof construction, indoor partition wall, floor paving, ceiling construction, interior decoration, electrical equipment installation, water heating equipment installation, air conditioning equipment installation and system debugging are T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15, T16, T17, T18, T19, T20, T21, T22, T23, T24, T25, T26, T27, T28, T29, T30, T31, T3210 , T 11 and T 12 , the total construction time of the entire project can be calculated. The specific calculation formula is as follows:

[0021] T 总 =T1+T2+T3+T4+T5+T6+T7+T8+T9+T 10 +T 11 +T 12

[0022] Among them, T 总 Indicates the total construction time of the entire project;

[0023] Then the total construction time of the whole project is T 总 Divide into 100 equal parts, use red, yellow and green to represent different stages. The initial stage of the project is red, representing the beginning of the project. As the project progresses, the progress gradually transitions to yellow, indicating that the project is gradually advancing. Finally, when the project is close to completion, the progress will reach dark green, indicating that the project is about to end. This color matching method can be displayed in real time on the interactive interface, which can intuitively reflect the progress of the project and help monitor and evaluate the actual situation of the project progress. The specific code to achieve this display effect is as follows:

[0024]

[0025] The above code uses the matplotlib library to draw the progress bar, analyzes the project progress from the BIM model as the predicted progress, and transmits the time data and predicted progress data of each construction process to the progress comparison module through the progress display module.

[0026] As a further solution of the present invention: the progress comparison module can provide an interactive interface, and the staff can input the project progress of the current project and the time from the start of construction to the present in the interactive window, and then compare the current actual project progress with the predicted progress, calculate the actual project progress and the predicted progress for comparison, and then calculate the time difference between the actual project progress and the predicted progress. The time difference can be used to intuitively judge the project gap between the current actual project progress and the predicted progress, which is convenient for management personnel to adjust the construction speed according to the construction period.

[0027] As a further solution of the present invention: the engineering entity structure association module can automatically associate the construction progress information in the BIM model, and realize automatic measurement of the construction progress by comparing it with the actual situation of the current project, and estimate the construction time required for the remaining project according to the current construction progress and construction speed, and calculate the time required to complete the remaining project according to the current progress according to the completed project volume and the time consumed. The specific calculation formula is as follows:

[0028]

[0029] Where: T n It indicates the time required to complete the remaining work according to the current progress, W a Indicates the amount of work that has been completed, W Z Indicates the total amount of the project, T0 is the time consumed;

[0030] When T n ≤T g -T0 means that the project can be completed within the design period according to the current construction speed, so the construction speed does not need to be accelerated unless necessary;

[0031] When T n >T g -T0 means that the current construction speed cannot be completed within the design period of the project, so it is necessary to speed up the construction;

[0032] Where: T g Represents the design duration market of the project.

[0033] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. The present invention trains the BIM model by collecting historical engineering data and automatically associates the BIM model with the engineering structure, thereby realizing the intuitive display and automatic measurement of the engineering progress. This association enables engineering managers to intuitively observe the progress of the current project through the BIM model. By representing the progress of the project at different stages with three colors: red, yellow, and green, the initial stage of the project is red, and as the project progresses, it gradually transitions to yellow and finally reaches dark green. Managers can understand the actual progress of the project at a glance. This intuitive color matching method is displayed in real time on the interactive interface, which helps to monitor and evaluate the actual situation of the project progress, making the management of the project progress more intuitive and efficient.

[0035] 2. The present invention provides a comparison between the actual project progress and the predicted progress through a progress comparison module. By calculating the time difference between the actual project progress and the predicted progress, managers can intuitively understand the gap between the current project progress and the expected plan. This comparison can help managers adjust the construction speed in time to ensure that the project is completed on time. Through automatic measurement and predicted progress comparison, managers can better understand the progress of the project and take timely measures to ensure the smooth progress of the project.

[0036] 3. The present invention trains the BIM model through advanced technologies such as deep network learning technology and convolutional neural network technology, and adjusts the model parameters through a large amount of data to improve the accuracy and generalization ability of the BIM model. This technical means enables the system to more accurately predict the progress of the project, help managers better plan and adjust the progress of the project. Through automated data processing and model training, the system can accurately analyze project information and provide timely feedback, thereby improving the efficiency and accuracy of project management, helping managers better control the progress of the project, and reducing management costs and risks.

[0084]

[0085] Where: T n It indicates the time required to complete the remaining work according to the current progress. a Indicates the amount of work that has been completed, W Z Indicates the total amount of the project, T0 is the time consumed;

[0086] When T n ≤T g -T0 means that the project can be completed within the design period according to the current construction speed, so the construction speed does not need to be accelerated unless necessary;

[0087] When Tn >T g -T0 means that the current construction speed cannot be completed within the design period of the project, so it is necessary to speed up the construction;

[0088] Where: T g Represents the design duration market of the project.

This intelligent project management method helps to reduce management costs and risks, enables managers to better control the progress of the project, and ensures the successful completion of the project.

[0090] When in use, the BIM model is trained through advanced technologies such as deep network learning technology and convolutional neural network technology, and the model parameters are adjusted through a large amount of data to improve the accuracy and generalization ability of the BIM model. This technical means enables the system to more accurately predict the progress of the project and help managers better plan and adjust the progress of the project. Through automated data processing and model training, the system can accurately analyze project information and provide timely feedback, thereby improving the efficiency and accuracy of project management, helping managers better control the progress of the project and reducing management costs and risks.

[0092] The first step is to collect multiple completed engineering information from the project management system, construction log, progress plan report, acceptance report and construction contract through the engineering data acquisition module, and clean, organize and convert the information into a format that matches the form of the model training module. Then, the database module inserts the information encryption unit and the information editing unit to ensure the data security of the engineering information during transmission and storage, and provides an information editing window for manual modification of abnormal data to ensure the accuracy of the engineering data.

[0093] The second step is to use deep network learning technology to establish a BIM model. The model is based on the scale, function and design requirements of the current engineering project.
