Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to an information management system for prefabricated buildings based on BIM. Background Art

[0002] The core of BIM is to establish a virtual three-dimensional model of a building project and use digital technology to provide a complete building project information database that is consistent with the actual situation. This information database not only contains geometric information, professional attributes, and status information describing building components, but also contains status information of non-component objects (such as spaces and movement behaviors). With the help of this three-dimensional model containing building project information, the degree of information integration of building projects is greatly improved, thus providing a platform for the exchange and sharing of project information for relevant stakeholders of building projects.

[0003] After retrieval, a Chinese invention patent with the patent number CN107958101A discloses an information management system and method for prefabricated buildings based on BIM, including productizing house types, establishing a model for integrated civil engineering and decoration design; splitting components of the integrated design model to form a BIM model; combining the BIM model with the construction sequence to form a 4D progress model, and using the 4D progress model to simulate the construction site; managing the production, transportation, installation, and operation and maintenance of components through the BIM model. The present invention provides platform support for the information management of prefabricated buildings and helps the development of prefabricated buildings.

[0004] However, the above system can only provide platform support for the information management of prefabricated buildings during use, ensuring the service life of prefabricated buildings, but lacks the control and adjustment of the overall progress of the building project during the construction process, and it is also difficult to effectively solve the problems of faults and costs in the project. Therefore, an information management system for prefabricated buildings based on BIM is needed. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies in the prior art, such as the lack of control and adjustment of the overall progress of the building project during the construction process, and the difficulty in effectively solving the problems of faults and costs in the project, and to propose an information management system for prefabricated buildings based on BIM.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An information management system for prefabricated buildings based on BIM, including a BIM-based management host. The interior of the management host includes a database, an information data system, a central processing system, a management module, an alarm module, a construction time entry module, and a work log upload module. The database inputs external BIM building information. The information data system collects information data in the current construction project. The interior of the information data system includes a data collection module, a data entry module, a data processing module, and a building fault acquisition module;

[0008] The information data system is communicatively connected to the central processing system. The interior of the central processing system includes a cost total module, a model establishment module, a model comparison module, and a progress identification module. The central processing system generates a BIM data model based on the information in this construction project, identifies the progress of the project according to the generated BIM data model, and at the same time calculates the total cost of the project according to the progress of the project;

[0009] The central processing system is communicatively connected to the management module. The interior of the management module includes a project adjustment module, a fault resolution module, a cost comparison module, an influencing factor calculation module, and a cost total module. The management module adjusts the progress of the project in real time. At the same time, the management module processes the problems existing in the project. The management module judges the influencing factors between each module of the project according to the input information.

[0010] The above technical solution further includes:

[0011] Staff enter the daily construction time through the construction time entry module, and staff upload the daily work log through the work log upload module.

[0012] The data collection module collects data of the construction project. The collected content includes the quantity of raw materials consumed in a single-day project, the acceptance pass rate of the construction project, and the attendance rate of construction workers. The data collection module transmits the collected data to the data entry module.

[0013] The data entry module enters the received data. The entered data is transmitted to the database for storage. The data entry module transmits the data to the data processing module. The data processing module preliminarily processes the data according to the timeliness of the data, retains the data with the highest timeliness, and at the same time the building fault acquisition module summarizes the problems existing in the entered data to generate a building fault summary report.

[0014] The model establishment module generates a BIM information model based on the information collected in the information data system. The generated BIM information model is compared with the remaining models in the database through the model comparison module, and then deep learning is performed to correct the BIM information model.

[0015] Each work node of the construction project is split according to the corrected BIM information model, and then the split nodes are combined into corresponding modules. The progress recognition module calculates the completion degree of each module according to the acquired information data, and the cost total module calculates the total funds required for the project in real time according to the funds consumed by the module progress.

[0016] The project adjustment module adjusts the subsequent construction direction according to the daily completion of the construction project in the central processing system. The fault resolution module processes the existing faults according to the generated building fault summary report. When the fault resolution module cannot handle the faults, the fault resolution module transmits the data to the alarm module, and an alarm is issued through the alarm module to accelerate the evacuation of surrounding personnel.

[0017] The cost comparison module traces the capital deviation existing in the construction process according to the total cost in the cost total module. The influencing factor calculation module calculates the modules composed of project nodes and calculates the influencing factors of the modules on the overall construction. The efficiency conversion module converts the influencing factors in the influencing factor calculation module into the construction efficiency of the building, and makes overall allocation of the modules with high construction efficiency and the modules with low construction efficiency.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, during use, through the data acquisition module, data entry module, and data processing module in the information data system, the data of the construction project can be effectively acquired and processed. At the same time, through the coordinated use of the cost total module, model establishment module, model comparison module, and progress recognition module inside the central processing system, a BIM information model is generated according to the data in the information data system, and the generated BIM information model is compared with the remaining models in the database through the model comparison module, and then deep learning is performed to correct the BIM information model. The corrected BIM information model can split each work node of the construction project, and then the cost total module calculates the total funds required for the project in real time according to the funds consumed by the module progress.

[0020] 2. In the present invention, the engineering adjustment module adjusts the subsequent construction direction according to the daily completion situation of the construction project in the central processing system, and the influence factor calculation module calculates the components of the module to calculate the influence factors of the module on the overall construction. The efficiency conversion module converts the magnitude of the influence factors in the influence factor calculation module into the construction efficiency, and coordinates and distributes the modules with high construction efficiency and low construction efficiency, thereby greatly improving the efficiency and safety of the construction project.
