[0018] The overall concept of the technical solution provided in this application is as follows: This application provides a method, device, and platform for monitoring building construction safety using BIM. By combining BIM technology with real-time data acquisition, dynamic safety monitoring and intelligent early warning of the construction site can be achieved.
[0019] Specifically, firstly, a 3D BIM model is constructed as the monitoring platform by acquiring basic information about the target construction site; secondly, a distributed sensor network is used to collect real-time data on the behavioral trajectories of construction personnel and the operational data of construction equipment, and this real-time data is visualized in the BIM model to achieve a dynamic presentation of the construction site status; thirdly, the real-time construction status is analyzed based on a safety constraint model to identify warning behaviors of construction personnel and equipment and generate warning identification results; finally, corresponding alarms are triggered based on the warning identification results, and the safety management system is linked to respond and process, enabling timely handling of safety hazards.
[0020] After introducing the basic principles of this application, various non-limiting embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0021] Example 1, as Figure 1 As shown in the embodiment of this application, a method for monitoring building construction safety using BIM is provided, the method comprising: S100: Determine the target construction site and obtain basic data information of the target construction site.
[0022] Specifically, the first step is to identify the target construction site that requires safety monitoring and obtain its basic information. Basic information refers to various fundamental information related to the construction site, including environmental, geographical, personnel, and equipment information.
[0023] By acquiring basic information about the target construction site, the necessary data foundation is provided for subsequent BIM modeling, thereby enabling accurate modeling of the construction site.
[0024] S200: Based on the aforementioned basic data information, construct a three-dimensional BIM model of the target construction site.
[0025] Specifically, after acquiring basic data, a 3D BIM model of the target construction site is constructed based on this data. Using BIM modeling software, information from the basic data regarding the site's layout and spatial structure is converted into a 3D model, and information about construction personnel and equipment is integrated into this model. Specifically, first, the basic 3D structure of the construction site is constructed based on the basic data, including terrain, buildings, roads, and other infrastructure. Then, information such as activity areas for construction personnel and working areas for construction equipment is added to this basic structure, enabling the 3D BIM model to fully represent the overall layout and information distribution of the construction site.
[0026] By constructing a 3D BIM model, a basic digital platform is provided for subsequent real-time data acquisition and safety monitoring.
[0027] S300: Real-time collection of behavioral trajectory data of construction personnel at the target construction site, and collection of equipment operation data of construction equipment at the target construction site.
[0028] Specifically, a distributed sensor network is deployed at the target construction site to collect real-time data on construction personnel and equipment. For construction personnel, their real-time location coordinates are collected, recording their movement trajectories on the construction site, thus obtaining behavioral trajectory data. This data reflects the activities and movement patterns of the construction personnel on the construction site. For construction equipment, its operational status data is collected, including equipment operating parameters, operating position, and operational status. This data reflects the real-time operation of the construction equipment.
[0029] By collecting this data in real time, we can provide data support for subsequent visualization and safety monitoring in the BIM model.
[0030] S400: Visualize the behavior trajectory data and the equipment operation data in the 3D BIM model to obtain the real-time construction status of the target construction site.
[0031] Specifically, the collected behavioral trajectory data and equipment operation data are imported into the constructed 3D BIM model for visualization, thereby obtaining the real-time construction status of the target construction site. Specifically, the real-time location of construction personnel is displayed in the 3D BIM model as dynamic markers, and their movement path is shown through trajectory lines. Simultaneously, the operation data of construction equipment is displayed in the model as equipment icons and parameter labels, reflecting the real-time working status of the equipment.
[0032] By visualizing data in a 3D BIM model, the real-time construction status of the construction site can be intuitively grasped, including the distribution and movement of construction personnel and the operating status of construction equipment, providing a visual basis for subsequent safety monitoring and early warning.
[0033] S500: Identify warning operation behaviors based on the real-time construction status and obtain warning identification results. The warning operation behaviors include operation behaviors of construction personnel and construction equipment that do not meet safety standards.
[0034] Specifically, the early warning operation behaviors include those of construction personnel and equipment that do not meet safety standards. Specifically, a pre-set safety constraint model is used to analyze the real-time construction status. For construction personnel, this identifies whether they have entered hazardous areas or engaged in unsafe behaviors such as excessive crowding. For construction equipment, it primarily identifies whether its operating parameters exceed safe ranges and whether equipment spacing meets safety requirements.
[0035] By identifying early warning actions based on real-time construction status, potential safety hazards at the construction site can be detected promptly, enabling real-time monitoring of construction safety. The early warning identification results visually reflect the safety status of the construction site, providing a basis for subsequent early warning processing.
[0036] S600: Trigger an alarm based on the warning identification result and link the security management system for response processing.
[0037] Specifically, when the early warning identification result indicates a safety hazard, the corresponding alarm will be automatically triggered. For different types of early warning identification results, corresponding emergency response plans will be generated. These plans will be sent to the safety management system, which will then execute the appropriate safety measures according to the preset processing procedures.
[0038] By triggering alarms and linking them with the safety management system, potential safety hazards at the construction site can be detected and addressed promptly, thereby effectively preventing safety accidents and improving the level of safety management at the construction site.
[0039] Furthermore, the basic data information includes site foundation information and construction foundation information, wherein the construction foundation information includes construction personnel information and construction equipment information; based on the basic data information, a 3D BIM model of the target construction site is constructed, including: S210: Based on the basic data information, extract the site basic information, and construct the first BIM model of the target construction site according to the site basic information; S220: Based on the basic data information, extract the construction equipment information, associate the construction equipment information with the first BIM model, and generate a second BIM model; S230: Based on the basic data information, extract the construction personnel information, associate the construction personnel information with the second BIM model, and obtain the three-dimensional BIM model of the target construction site.
[0040] Specifically, the basic data information includes site basic information and construction basic information. Site basic information includes the topography, spatial dimensions, and geographical coordinates of the construction site; construction basic information includes construction personnel information and construction equipment information. Construction personnel information includes the number of construction personnel, their job categories, and their certification status, while construction equipment information includes equipment type, equipment parameters, and equipment quantity.
[0041] When constructing a 3D BIM model based on basic data, the process begins with extracting site foundation information from the basic data. This information is then used to build the first BIM model of the target construction site. This first BIM model primarily includes basic terrain, buildings, roads, and other infrastructure information. Next, construction equipment information is extracted from the basic data and linked to the first BIM model to generate a second BIM model. This second model adds information such as the spatial layout and parameters of the construction equipment to the infrastructure model. Finally, construction personnel information is extracted from the basic data and linked to the second BIM model, resulting in a complete 3D BIM model. This model not only includes site and equipment information but also integrates information such as the distribution and job positions of the construction personnel.
[0042] By constructing the model in stages, the final 3D BIM model can comprehensively reflect various information on the construction site, providing a complete digital foundation for subsequent safety monitoring.
[0043] Furthermore, real-time data on the behavioral trajectories of construction workers at the target construction site and data on the operational status of construction equipment at the target construction site are collected, including: S310: Constructing a distributed sensor network; S320: Collect the location coordinates of the construction personnel and the operating status data of the construction equipment through the distributed sensor network; S330: Based on the location coordinate information, determine the actual location of the construction worker, and generate the behavior trajectory data according to the actual location; S340: The operating status data is summarized according to time sequence to generate the device operating data.
[0044] Specifically, firstly, a distributed sensor network is constructed. This network, through the deployment of multiple sensor nodes, achieves comprehensive sensing coverage of the construction site, providing fundamental network support for data collection. Secondly, real-time data collection from the construction site is conducted through the distributed sensor network. For construction personnel, their real-time location coordinates are collected; for construction equipment, operational status data, including operating speed, workload, and location information, are collected. Then, based on the collected location coordinates, the actual location of the construction personnel on the construction site is determined. By continuously recording the actual location of the construction personnel, behavioral trajectory data reflecting their movement is generated, which reveals the activity patterns of the construction personnel. Simultaneously, the collected equipment operating status data is organized and summarized in chronological order to generate complete equipment operating data. This data includes the operating parameters of the equipment at different points in time, reflecting the operating trends of the equipment. Through real-time data collection of personnel and equipment at the construction site, a data foundation is provided for subsequent safety monitoring.
[0045] Furthermore, constructing a distributed sensor network includes: S311: Configure location tags for construction personnel at the target construction site; S312: Configure an operation status acquisition device for the construction equipment at the target construction site; S313: Connect the positioning tag and the running status collector to the backend management terminal to generate the distributed sensor network.
[0046] Specifically, firstly, location tags are installed on construction workers at the target construction site. These tags are small, portable devices that can be worn on workers' safety helmets or work clothes, transmitting real-time location information via a built-in positioning module. These tags are characterized by low power consumption and high precision, ensuring continuous operation. Secondly, operational status data acquisition devices are installed on the construction equipment at the target site. These devices collect operating parameters such as operating speed, workload, and location information through sensors. Then, the location tags and operational status data acquisition devices are wirelessly connected to a backend management system. The backend management system receives data from each acquisition device through a unified data interface, forming a distributed sensor network covering the entire construction site. This enables comprehensive monitoring of personnel and equipment at the construction site, providing the hardware foundation for data collection.
[0047] Furthermore, based on the real-time construction status, the early warning operation behavior is identified, and the early warning identification result is obtained, including: S510: Construct a first safety constraint model, identify early warning operation behaviors based on the first safety constraint model for the real-time construction status, and obtain a first identification result. The first safety constraint model is a safety constraint model for the construction personnel. S520: Construct a second safety constraint model, identify early warning operation behaviors based on the second safety constraint model for the real-time construction status, and obtain a second identification result. The second safety constraint model is a safety constraint model for the construction equipment. S530: Summarize the first identification result and the second identification result to generate the warning identification result.
[0048] Specifically, firstly, a primary safety constraint model is constructed for construction workers. This model is based on the safety operating procedures for construction workers and includes constraints such as the hazard level of the construction area and personnel density limits. By analyzing the real-time construction status based on this model, unsafe behaviors of construction workers can be identified, such as entering hazardous areas or excessive personnel gathering, and a primary identification result can be generated.
[0049] Secondly, a second safety constraint model for construction equipment is constructed. This model is based on the safety operation specifications for construction equipment and includes constraints such as equipment operating parameter limits and safe distances between equipment. Analyzing the real-time construction status based on this model can identify abnormal operating states of the equipment, such as overspeeding or excessively close proximity of equipment, and generate a second identification result.
[0050] Subsequently, the first and second identification results are systematically summarized to generate a complete early warning identification result. This result comprehensively reflects the various safety hazards existing at the construction site, providing a basis for judgment in subsequent early warning handling.
[0051] Furthermore, a first security constraint model is constructed, including: S511: Divide the target construction site into multiple construction areas; S512: Determine the regional hazard level and regional personnel density threshold for each of the construction areas based on their safety levels; S513: Based on the area hazard level, the area population density threshold, and the three-dimensional BIM model, generate a first safety constraint model.
[0052] Specifically, to construct the first safety constraint model, the target construction site is first divided into zones. Based on the spatial layout and construction progress, the entire construction site is divided into multiple functional construction areas, such as construction work areas, material storage areas, and machinery and equipment areas. Secondly, safety parameters are set for the safety level of each construction area. Based on the functional characteristics and operational risks of each area, the hazard level of each area is determined, and a corresponding area hazard degree is set. Simultaneously, based on safety regulations, personnel density thresholds are set for each area to control the degree of personnel gathering within the area. Then, the area hazard degree and personnel density thresholds are correlated with the 3D BIM model to generate the first safety constraint model. This model combines the spatial information of the construction site with safety constraints, achieving spatialized safety management of construction personnel activities.
[0053] Furthermore, a second security constraint model is constructed, including: S521: For the construction equipment at the target construction site, determine the threshold range of operating parameters; S522: Based on the aforementioned operating parameter threshold range, construct the operating parameter constraint space for the construction equipment; S523: Determine the safe operating distance of the construction equipment based on the spatial position relationship of the construction equipment in the three-dimensional BIM model; S524: Generate the second safety constraint model based on the operating parameter constraint space, the safe operating distance, and the three-dimensional BIM model.
[0054] Specifically, to construct the second safety constraint model, firstly, the threshold ranges of operating parameters are determined for various construction equipment at the target construction site. Based on the equipment's technical specifications and safe operating procedures, safety threshold ranges are set for parameters including operating speed, workload, and operating time. Secondly, based on the set operating parameter threshold ranges, an operating parameter constraint space for the construction equipment is constructed. This constraint space defines the safety boundaries of the equipment's operating parameters, providing a basis for judging the equipment's operating status.
[0055] Then, based on the spatial distribution of construction equipment in the 3D BIM model, the positional relationships between the equipment are analyzed to determine the safe operating distances that need to be maintained between various types of equipment. These distances take into account factors such as the equipment's working range and operational characteristics. Next, the constraints of operating parameters, spatial constraints, and safe operating distances are linked to the 3D BIM model to generate a second safety constraint model. This model provides comprehensive constraints on the operating status and spatial position of construction equipment, offering evaluation criteria for the safety monitoring of construction equipment.
[0056] Furthermore, based on the warning identification result, an alarm is triggered, and the security management system is linked to perform response processing, including: S610: Determine whether the warning recognition result is the first recognition result or the second recognition result; S620: When the warning identification result is the first identification result, a safety warning for construction personnel is triggered, and an emergency response plan for construction personnel is generated; S630: When the warning identification result is the second identification result, a construction equipment safety warning is triggered, and an emergency response plan for the construction equipment is generated; S640: The emergency response plan is sent to the safety management system for execution.
[0057] Specifically, firstly, the warning identification results are categorized to determine whether the result is a primary identification result targeting construction personnel or a secondary identification result targeting construction equipment, thus determining the subsequent handling direction. When the warning identification result is a primary identification result, i.e., unsafe behavior by construction personnel is detected, a safety warning for construction personnel is triggered. Simultaneously, a corresponding emergency response plan is generated based on the warning type, such as issuing evacuation orders and adjusting personnel distribution. When the warning identification result is a secondary identification result, i.e., abnormal condition of construction equipment is detected, a safety warning for construction equipment is triggered. Simultaneously, a corresponding emergency response plan is generated based on the warning type, such as equipment deceleration and emergency shutdown. Afterwards, the generated emergency response plan is sent to the safety management system through the system interface. Upon receiving the emergency response plan, the safety management system will carry out the corresponding emergency response work according to the preset execution process, thereby achieving timely warning and rapid handling of safety hazards and effectively improving the safety level of the construction site.
[0058] In summary, the construction safety monitoring method using BIM provided in this application has the following technical effects: The process begins with identifying the target construction site and acquiring its basic information to support subsequent modeling and monitoring. Based on this information, a 3D BIM model of the target construction site is constructed, providing a platform for real-time monitoring and allowing for a clear visual representation of the site's status. Real-time data collection of worker behavior and equipment operation data enables continuous monitoring of the construction site. This data is then visualized within the 3D BIM model, providing a dynamic and intuitive understanding of the site's condition. Based on the real-time construction status, warning actions are identified, and these actions, which do not meet safety standards, are used to promptly detect potential safety hazards. Alarms are triggered based on these warnings, and the safety management system is activated to respond to any safety hazards detected, ensuring the safety of the construction site.
