Description

Technical Field

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

[0002] Currently, with the development of computer technology in the construction industry, Building Information Modeling (BIM) has become very popular because it can visualize the overall progress of the project.

[0003] The existing technology for construction site progress management has the following defects:

[0004] 1. Construction progress management is usually presented in the form of Gantt charts and network construction drawings, which cannot intuitively reflect which component of the building corresponds to the construction process of a specific development task.

[0005] 2. There are also many factors that hinder construction during the construction of the building, such as the discovery of hidden cemeteries and important pipelines. These obstacles are collectively referred to as risk sources. The specific way in which the risk source affects the normal construction of the construction site cannot be reflected intuitively, and can only be recorded in text, which is inconvenient to use. Summary of the invention

[0006] The purpose of the present invention is to provide a technical solution of a construction site progress management method and system based on 3D BIM in view of the deficiencies in the prior art. The construction site progress management method can not only form a 3D Gantt chart in a visual way, but also present each BIM component in a 3D visual form, which can effectively express the construction progress and reflect the expected effect and completion progress that the building can achieve on a specified date. Moreover, after the entire building is completed, the 3D Gantt chart can be used to complete the time backtracking and display the corresponding building component information in sequence. The construction site progress management system is based on a 3D BIM model. By directly binding tasks to each building component in the scene, the attributes of each component are reflected in a 3D visual way, which greatly improves the intuitiveness of the construction site progress management and can effectively manage and constrain the construction progress.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A construction site progress management method based on three-dimensional BIM, characterized by comprising the following steps:

[0009] Step 1: Import the 3D BIM model, obtain the geometric structure and topological structure by parsing the BIM model, and store the topological structure tree in the relational database;

[0010] Step 2: For the topology structure tree of the BIM model, set the attributes of each component through progress editing and store them in the relational database;

[0011] Step 3: Identify the risk sources that occur during the construction process in the BIM model, bind them to the corresponding BIM components, and then save the risk source information in the relational database;

[0012] Step 4. Display the task bar corresponding to each component through progress display and filter by current time.

[0013] This construction site progress management method can not only form a three-dimensional Gantt chart in a visual way, but also present each BIM component in a three-dimensional visual form, which can effectively express the construction progress and reflect the expected effect and completion progress that the building can achieve on the specified date. Moreover, after the entire building is completed, the three-dimensional Gantt chart can be used to trace back the time and display the corresponding building component information in sequence.

[0014] Furthermore, when the 3D BIM model in Step 1 is imported, the model file is read and parsed by the 3D BIM engine.

[0015] Furthermore, the attributes in step Step 2 include construction progress information, which is bound to the BIM components. When the BIM model is imported into the system, the BIM components are selected one by one and the construction progress information is filled in. During the construction process, the progress completion information of the BIM components is continuously updated. The construction progress information includes the task ID and the start and end time of the task.

[0016] Furthermore, the risk sources in Step 3 include discovering hidden targets and obstacles caused by one's own reasons.

[0017] Furthermore, the filtering by current time in step 4 specifically includes the following steps:

[0018] Step 4.1 Make the components whose time has passed visible, and make the components whose time has not yet arrived virtual;

[0019] Step 4.2 Components that match the construction time are displayed in primary colors, and components that do not match the construction time are displayed in warning colors;

[0020] Step 4.3 The components that are under construction are displayed in a faded manner. The higher the completion percentage, the darker the color.

[0021] A construction site progress management system based on three-dimensional BIM, characterized by: including:

[0022] 3D BIM engine, used to read and parse the geometric and topological structures of BIM models, and also as a rendering engine, providing the progress display module with rendering basis;

[0023] The model import module is used to import the three-dimensional BIM model, obtain the topological structure tree of the BIM model, and store the topological structure tree in the relational database;

[0024] The progress editing module is used to set the attributes of each component through progress editing according to the topological structure tree of the BIM model and store them in the relational database;

[0025] The process management module is used to identify the risk sources that occur during the construction process in the BIM model, bind them to the corresponding BIM components, and then save the risk source information in the relational database;

[0026] And the progress display module is used to display the task bar corresponding to each component and filter by current time.

[0027] The construction site progress management system is based on the three-dimensional BIM model. By directly binding tasks to each building component in the scene, the attributes of each component are reflected in a three-dimensional visual way, which greatly improves the intuitiveness of the construction site progress management and can effectively manage and constrain the construction progress.

[0028] Furthermore, when the 3D BIM model is imported, the model file is read and parsed by the 3D BIM engine.

[0029] Furthermore, the attributes include construction progress information, which is bound to the BIM components. When the BIM model is imported into the system, the BIM components are selected one by one and the construction progress information is filled in. During the construction process, the progress completion information of the BIM components is continuously updated. The construction progress information includes the task ID and the start and end time of the task.

[0030] Furthermore, risk sources include obstacles caused by hidden goals and self-cause.

[0031] Furthermore, filtering by current time specifically includes the following steps:

[0032] Make components whose time has passed visible, and components whose time has not yet arrived virtual;

[0033] Components that match the construction time are displayed in primary colors, and components that do not match the construction time are displayed in warning colors;

[0034] Components that are under construction are displayed in a faded manner. The higher the completion percentage, the darker the color.

[0036] 1. The construction site progress management method of the present invention can not only form a three-dimensional Gantt chart in a visual way, but also present each BIM component in a three-dimensional visual form, which can effectively express the construction progress and reflect the expected effect and completion progress that the building can achieve on a specified date. Moreover, after the entire building is completed, the three-dimensional Gantt chart can be used to trace back the time and display the corresponding building component information in sequence.

[0037] 2. The construction site progress management system of the present invention is based on a three-dimensional BIM model. By directly binding tasks to each building component in the scene, the attributes of each component are reflected in a three-dimensional visual manner, which greatly improves the intuitiveness of construction site progress management and can effectively manage and constrain the construction progress.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only embodiments of a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0043] In the following description, specific embodiments of the present invention will be described with reference to steps and symbols of operations performed by one or more computers, unless otherwise stated. Therefore, it will be understood that these steps and operations, which are several times referred to as being performed by a computer, include manipulation by a computer processing unit of electronic signals representing data in a structured form.

However, the principles of the present invention are described in the above text, which does not represent a limitation, and those skilled in the art will understand that the various steps and operations described below can also be implemented in hardware.

[0044] As used herein, the terms "component," "module," "system," "interface," "process," and the like are generally intended to refer to a computer-related entity: hardware, a combination of hardware and software, software, or software in execution. For example, a component can be, but is not limited to, a process running on a processor, a processor, an object, an executable application, a thread of execution, a program, and / or a computer. By way of illustration, both an application running on a controller and the controller can be components.

[0045] Moreover, the claimed subject matter may be implemented as a method, apparatus, or article of manufacture that uses standard programming and / or engineering techniques to produce software, firmware, hardware, or any combination thereof to control a computer to implement the disclosed subject matter. The term "article of manufacture" as used herein is intended to include a computer program that can be accessed from any computer-readable device, carrier, or medium. Of course, those skilled in the art will recognize that many modifications may be made to this configuration without departing from the scope or spirit of the claimed subject matter.

[0046] like Figure 1 As shown, a construction site progress management method based on three-dimensional BIM of the present invention comprises the following steps:

[0047] Step 1: Import the 3D BIM model, obtain the geometric structure and topological structure by parsing the BIM model, and store the topological structure tree in the relational database;

[0048] When a 3D BIM model is imported, the model file is read and parsed through the 3D BIM engine.

[0049] Step 2: For the topology structure tree of the BIM model, set the attributes of each component through progress editing and store them in the relational database;

[0050] The properties include construction progress information, which is bound to the BIM components. When the BIM model is imported into the system, the BIM components will be selected one by one and the construction progress information will be filled in. During the construction process, the progress completion information of the BIM components will be continuously updated. The construction progress information includes the task ID and the start and end time of the task.

[0051] The task ID and the model component ID form a corresponding relationship, and the task ID and the model component ID are mapped through a mapping table, as shown in Table 1:

[0052] Task ID Component ID Other attributes 1 Other attributes 2 …… T012 C5054 Cement beams on the second floor 60*80 T013 C5055 East side column of the second floor 60*60 T014 C5056 South side column of the second floor 60*60

[0053] Table 1

[0054] As shown in Table 1, through the construction task ID, its component ID can be quickly queried in this table. Similarly, the corresponding construction task ID can also be quickly queried according to the component ID.

[0055] Step 3: Identify the risk sources that occur during the construction process in the BIM model, bind them to the corresponding BIM components, and then save the risk source information in the relational database;

[0056] Risk sources include hidden targets and obstacles caused by one's own reasons.

[0057] Discover hidden targets, such as ancient tombs, underground pipelines, caves, underground rivers, surface buildings that need to be demolished, etc. These targets already exist before construction and need to be processed according to specific procedures before construction can continue.

[0058] If there are obstacles caused by one's own reasons, such as accidental damage to construction equipment and facilities, shortage of construction materials, etc., construction cannot continue until these problems are resolved.

[0059] Risk sources are usually not effectively anticipated before construction begins. As the construction process progresses, they emerge one by one, forming obstacles to the construction process. This information will also be marked as an attribute on the BIM model on the BIM component. Usually, the attribute is filled in on the corresponding BIM component if the construction of the component is hindered.

[0060] Step 4. Display the task bar corresponding to each component through progress display and filter by current time.

[0061] Filtering by current time includes the following steps:

[0062] Step 4.1 Make the components whose time has passed visible, and make the components whose time has not yet arrived virtual;

[0063] Step 4.2 Components that match the construction time are displayed in primary colors, and components that do not match the construction time are displayed in warning colors;

[0064] Step 4.3 The components that are under construction are displayed in a faded manner. The higher the completion percentage, the darker the color.

[0065] This construction site progress management method can not only form a three-dimensional Gantt chart in a visual way, but also present each BIM component in a three-dimensional visual form, which can effectively express the construction progress and reflect the expected effect and completion progress that the building can achieve on the specified date. Moreover, after the entire building is completed, the three-dimensional Gantt chart can be used to trace back the time and display the corresponding building component information in sequence.

[0066] like Figure 2 As shown, a construction site progress management system based on three-dimensional BIM of the present invention includes:

[0067] 3D BIM engine, used to read and parse the geometric and topological structures of BIM models, and also as a rendering engine, providing the progress display module with rendering basis;

[0068] The model import module is used to import the three-dimensional BIM model, obtain the topological structure tree of the BIM model, and store the topological structure tree in the relational database;

[0069] When a 3D BIM model is imported, the model file is read and parsed through the 3D BIM engine.

[0070] The progress editing module is used to set the attributes of each component through progress editing according to the topological structure tree of the BIM model and store them in the relational database;

[0071] The properties include construction progress information, which is bound to the BIM components. When the BIM model is imported into the system, the BIM components will be selected one by one and the construction progress information will be filled in. During the construction process, the progress completion information of the BIM components will be continuously updated. The construction progress information includes the task ID and the start and end time of the task.

[0072] The construction progress information needs to be detailed to each BIM component. The construction progress information of any BIM component can include when the construction starts, when the construction ends, the current completion percentage, etc. It is bound to the BIM component as a fixed attribute.

[0073] The process management module is used to identify the risk sources that occur during the construction process in the BIM model, bind them to the corresponding BIM components, and then save the risk source information in the relational database;

[0074] Risk sources include hidden targets and obstacles caused by one's own reasons.

[0075] Discover hidden targets, such as ancient tombs, underground pipelines, caves, underground rivers, surface buildings that need to be demolished, etc. These targets already exist before construction and need to be processed according to specific procedures before construction can continue.

[0076] If there are obstacles caused by one's own reasons, such as accidental damage to construction equipment and facilities, shortage of construction materials, etc., construction cannot continue until these problems are resolved.

[0077] Risk sources are usually not effectively anticipated before construction begins. As the construction process progresses, they emerge one by one, forming obstacles to the construction process. This information will also be marked as an attribute on the BIM model on the BIM component. Usually, the attribute is filled in on the corresponding BIM component if the construction of the component is hindered.

[0078] And the progress display module is used to display the task bar corresponding to each component and filter it according to the current time. Especially when there is an abnormal construction progress, the three-dimensional components can be distinguished by color and a three-dimensional visual early warning can be issued.

[0079] Filtering by current time includes the following steps:

[0080] Make components whose time has passed visible, and components whose time has not yet arrived virtual;

[0081] Components that match the construction time are displayed in primary colors, and components that do not match the construction time are displayed in warning colors;

[0082] Components that are under construction are displayed in a faded manner. The higher the completion percentage, the darker the color.

[0083] The construction site progress management system is based on a three-dimensional BIM model. By directly binding tasks to each building component in the scene, the properties of each component are reflected in a three-dimensional visual way, which greatly improves the intuitiveness of construction site progress management and can effectively manage and constrain the construction progress. The task bar of the Gantt chart can reflect the task progress, and at the same time supports task progress warning, task visualization tracing and deduction.

[0084] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to achieve basically the same technical effects are all included in the protection scope of the present invention.
