Description

Technical Field

[0001] The present invention relates to the field of marine engineering technology, and in particular to a construction monitoring method and system based on a BIM model. Background Art

[0002] Since marine engineering involves multiple projects, there are a lot of safety risks in the construction process. Using traditional methods for real-time monitoring not only has delays, but also has low monitoring accuracy. It often requires technical personnel to monitor on site, which is cumbersome to operate.

[0003] At present, the accuracy of monitoring can be improved and the monitoring operation can be simplified by constructing a BIM model (Building Information Modeling) of marine engineering and then using the model for monitoring. However, the marine engineering BIM model often involves monitoring of structural integrity, engineering electromechanical, environmental impact assessment, construction progress, materials and marine topography and geology, which makes it impossible to monitor different BIM models at the same time, thereby making the monitoring efficiency and accuracy low. At the same time, only the marine engineering BIM model is used for monitoring. However, due to the different progress and construction efficiency of different construction teams in actual construction, the construction progress of the same marine engineering structure is not completely different, resulting in the marine engineering BIM model being unable to actually reflect the current specific real-time situation. As the scale of marine engineering projects increases, this error will be magnified, making it impossible to use it in actual engineering monitoring. Summary of the invention

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Embodiment 1

[0046] Please refer to Figure 1 , a construction monitoring method based on a BIM model provided by an embodiment of the present invention, comprising the following steps S101-S105:

[0047] Step S101: Generate a three-dimensional BIM model based on the target marine engineering design plan, obtain a construction schedule, and integrate the construction schedule into the three-dimensional BIM model to generate a four-dimensional BIM model.

[0048] In this embodiment, marine engineering is a complex field involving the development of marine resources, design, construction and maintenance of marine structures, and the application of BIM model technology in marine engineering can improve the efficiency and safety of design, construction and operation. The BIM model can provide a three-dimensional view, making the design intent more intuitive and easy to understand, and BIM helps to identify and resolve conflicts and inconsistencies in the design. It can also simulate the performance of buildings, such as structural strength, electromechanical operation, energy efficiency, lighting analysis, stress analysis, etc., and then automatically generate detailed construction drawings and documents to achieve construction planning and progress management, and in the later stage, it can also operate and maintain marine engineering.

[0049] As a preferred solution of this embodiment, generating a three-dimensional BIM model based on the target marine engineering design solution, obtaining a construction schedule, and combining the construction schedule into the three-dimensional BIM model to generate a four-dimensional BIM model specifically includes:

[0050] Based on the design drawings and preset specifications in the target marine engineering design plan, a terrain model, a structural model and an electromechanical model of the target marine engineering are created; the terrain model, the structural model and the electromechanical model are integrated to generate a three-dimensional BIM model; a construction schedule is obtained, and according to the construction schedule, a timeline corresponding to the three-dimensional BIM model is generated, and the timeline is combined with the three-dimensional BIM model to construct a four-dimensional BIM model.

[0051] In this embodiment, the target marine engineering design scheme includes design drawings and preset specifications, wherein the design drawings include but are not limited to technical document drawings, model geometry data, material attribute data, material performance data, design parameter specifications, and material supply chain information, and the preset specifications include but are not limited to project scope objectives, laws and regulations, legal standards, and environmental impact assessments, etc. The terrain model, structural model, and electromechanical model of the target marine engineering can be created by using the data of the design drawings such as technical document drawings, model geometry data, material attribute data, material performance data, design parameter specifications, and material supply chain information, as well as the design specifications combined with the project scope objectives, laws and regulations, legal standards, and environmental impact assessments, etc.

[0052] In this embodiment, the terrain model, the structural model and the electromechanical model are three key components of the three-dimensional BIM model. The terrain model, the structural model and the electromechanical model respectively reflect different types of information to support the planning, design, construction and operation of the construction project. Among them, the terrain model can reflect geographical information including the geographical location of the site, the surrounding environment, the terrain undulations, the geomorphic features, etc., and can also reflect the surface characteristics (such as coasts, vegetation, water bodies, roads, existing buildings, etc.), soil conditions (soil type, bearing capacity, permeability, etc.) and environmental data (climatic conditions, wind direction, sunshine analysis, etc.); and the structural model can reflect the architectural elements, material properties, mechanical properties, construction details and safety requirements of marine engineering. Among them, the architectural elements include the structural design of walls, floors, roofs, beams, columns, foundations, etc., the material properties include the type, strength, durability, weight, etc. of the structural materials, the mechanical properties include the bearing capacity, stability, seismic performance, etc. of the structure, the construction details include structural connections, prefabricated components, construction sequence and methods, and the safety requirements include the safety standards and specifications of the structure, including fire protection, wind protection, and earthquake resistance. The electromechanical model can reflect the piping system, electrical system, HVAC system, equipment information, control system and equipment maintenance operations in marine engineering. The piping system includes water supply and drainage pipes, heating and cooling pipes, ventilation pipes, etc. The electrical system includes cable wiring, electrical equipment, lighting system, power distribution system, etc. The HVAC system includes the layout and design of the HVAC (High Voltage Alternating Current, heating, ventilation and air conditioning) system. The equipment information includes the specifications and performance of electromechanical facilities such as pumps, fans, boilers, and air-conditioning units. The control system includes the building management system (BMS), energy management system (EMS) and other automated control systems. Maintenance operations include equipment maintenance plans, operation manuals and performance monitoring.

[0053] In this embodiment, the independent terrain model, structural model and electromechanical model are imported into a shared BIM environment, including but not limited to Revit, ArchiCAD, Bentley, etc., and the models are integrated into a unified BIM model using the link or merge function to coordinate the models. The collision detection tool of the BIM software is used to check the conflicts between different models, so that the model is adjusted to resolve the conflicts and ensure the coordination of the structure and electromechanical system with the terrain and building structure. Finally, data integration is performed to ensure that the information in all models (such as materials, dimensions, performance parameters, etc.) is consistent, and then the model is updated to reflect the latest design changes and construction information, so that the terrain model, structural model and electromechanical model can be integrated to generate the final three-dimensional BIM model.

[0054] In this embodiment, by acquiring and parsing the construction schedule, the timeline of the construction progress corresponding to the target marine project can be obtained, and then the timeline can be combined with the three-dimensional BIM model, and finally a four-dimensional BIM model of the relationship between time and three-dimensional structure can be constructed, so as to realize the simulated construction of the four-dimensional BIM model at the same time or the same construction stage, thereby obtaining the simulated construction data corresponding to the same construction stage.

[0055] Step S102: Perform construction simulation according to the four-dimensional BIM model, and obtain simulated construction data of each construction stage in the construction simulation.

[0056] As a preferred solution of this embodiment, the construction simulation is performed according to the four-dimensional BIM model, and the simulated construction data of each construction stage is obtained in the construction simulation, which specifically includes:

[0057] The time schedule for the construction simulation of the four-dimensional BIM model is set, and corresponding data acquisition interfaces are respectively added to the terrain model, the structural model and the electromechanical model in the four-dimensional BIM model, and each data acquisition interface is mapped for data acquisition; based on the time schedule, the construction simulation of the four-dimensional BIM model is performed, so that in the construction simulation, the construction data of the terrain model, the structural model and the electromechanical model in each construction stage are obtained from each data acquisition interface as simulated construction data.

[0058] In this embodiment, a time schedule is set for the construction simulation of the four-dimensional BIM model, and corresponding data acquisition interfaces are added to the terrain model, structural model and electromechanical model integrated into the four-dimensional BIM model for mapping, so that the construction simulation of the four-dimensional BIM model is carried out based on the time schedule. The construction process of the four-dimensional BIM model simulation technology includes construction sequence, schedule and resource allocation, etc., so that in the construction simulation, the construction data corresponding to the terrain model, structural model and electromechanical model in each construction stage are obtained from each data acquisition interface as simulated construction data.

[0059] Step S103: According to the preset inspection route of the target marine project, the target marine project is inspected and the inspection data is acquired in real time, so as to calibrate the inspection data according to the preset inspection route, generate the real-time construction data of the current target marine project, and then determine the actual construction stage of the current target marine project according to the real-time construction data.

[0060] As a preferred solution of this embodiment, the target marine project is inspected according to the preset inspection route of the target marine project, and the inspection data is obtained in real time, so as to calibrate the inspection data according to the preset inspection route, generate the real-time construction data of the current target marine project, and then determine the actual construction stage of the current target marine project according to the real-time construction data, which specifically includes:

[0061] In response to the user setting a corresponding preset inspection route according to the target marine project and the four-dimensional BIM model, and generating corresponding paths and inspection points according to the preset inspection route, and sending the paths and inspection points to the inspection robot, so as to control the inspection robot to inspect the target marine project; wherein the inspection points are stop points for the inspection robot to collect data, and the paths connect the inspection points; during the inspection process of the inspection robot, real-time inspection data of each inspection point is obtained, and the real-time inspection data of each inspection point is calibrated and analyzed according to the preset inspection route and the four-dimensional BIM model, so as to generate construction data corresponding to each inspection point as the real-time construction data of the current target marine project; according to the real-time construction data, the construction stage of each area of ​​the current target marine project is determined, and the construction stages of each area are aggregated to obtain the actual construction stage of the current target marine project as a whole.

[0062] In this embodiment, by responding to the user based on the target marine project and the four-dimensional BIM model, a preset inspection route designed by the user is obtained, and by setting the preset inspection route, a path and inspection points corresponding to the target marine project are generated, and the path and inspection points are sent to the inspection robot (or corresponding inspection equipment, data acquisition equipment, etc.) to control the inspection robot to inspect the target marine project.

[0063] In this embodiment, the inspection robot collects on-site data of the target marine project. Construction data can be collected on-site by using mobile devices, RFID tags, scanners and other tools, or on-site construction personnel can register the inspection robot on the path, so that construction progress information can be recorded and uploaded in a timely manner.

[0064] In this embodiment, during the inspection process of the inspection robot, the real-time inspection data of each inspection point is obtained, and then the real-time inspection data of each inspection point is analyzed by calibrating the preset inspection route and combining the four-dimensional BIM model, so that the real-time construction data of each inspection point in the corresponding area of ​​the four-dimensional BIM model can be obtained, and the construction stage of each area of ​​the current target marine project can be determined through the real-time construction data. For example, the construction stages of different areas may not be the same. For example, the target marine project may include area A, area B and area C, and the construction stage includes foundation construction, structural construction, upper module installation, pipeline and cable installation, electromechanical equipment installation, mooring system installation, integrity testing and debugging, and safety emergency response preparation. When area A and area C are in the construction stage of structural construction, area B may be in the foundation construction or other construction stages. Therefore, the construction stages of various regions can be aggregated to obtain the actual construction stage of the current target marine project as a whole. For example, when regions A and C are in the construction stage of structural construction, and region B is in the construction stage of foundation construction, regions A, B, and C are clustered to determine the item with the most identical construction stages, namely, the construction stage of structural construction, as the actual construction stage of the current target marine project as a whole.

[0065] Step S104: Determine the corresponding simulated construction data through the actual construction stage, perform a first comparison between the simulated construction data and the real-time construction data, and identify abnormal construction data based on the comparison result, thereby performing data positioning on the four-dimensional BIM model based on the abnormal construction data, and obtain the simulated construction data corresponding to the abnormal construction data as abnormal comparison data; wherein the simulated construction data and the real-time construction data both include a number of projects and their corresponding data information.

[0066] As a preferred solution of this embodiment, the corresponding simulated construction data is determined through the actual construction stage, the simulated construction data is first compared with the real-time construction data, and abnormal construction data is identified according to the comparison result, so as to locate the data of the four-dimensional BIM model according to the abnormal construction data, and obtain the simulated construction data corresponding to the abnormal construction data as the abnormal comparison data, which specifically includes:

[0067] Through the actual construction stage, the simulated construction data corresponding to the stage is determined in the four-dimensional BIM model; the data information corresponding to each project between the simulated construction data and the real-time construction data is compared for the first time, so as to determine that the data information of the same project between the simulated construction data and the real-time construction data exceeds the second preset threshold; if there is at least one project whose data information exceeds the second preset threshold, the data information of the project is marked as abnormal construction data, and the abnormal construction data is located based on the four-dimensional BIM model, and the corresponding model area to be corrected and the construction stage to be corrected are identified, so as to obtain the simulated construction data corresponding to the model area to be corrected and the construction stage to be corrected in the four-dimensional BIM model as abnormal comparison data.

[0068] In this embodiment, by determining the current actual construction stage of the target marine project, the simulated construction data corresponding to the actual construction stage can be determined in the four-dimensional BIM model, for example, the simulated construction data corresponding to the construction stage of the structure can be determined. Then, the data information corresponding to each project between the simulated construction data and the real-time construction data is first compared to determine that the data information of the same project between the simulated construction data and the real-time construction data exceeds the second preset threshold; wherein the second preset threshold can be set according to the actual situation. For example, with respect to real-time construction data, there are three different projects in region A (including: project A1, project A2 and project A3), and there are two different projects in region B and region C (region B includes project B1 and project B2, and region C includes project C1 and project C2); and with respect to simulated construction data, there are three different projects in region A' (including: project A1', project A2' and project A3'), and there are two different projects in region B' and region C' (region B' includes project B1' and project B2', and region C' includes project C1' and project C2'), and by comparing the data information between project A1 and project A1', project A2 and project A2', ..., project C2 and project C2', it is possible to determine which project's data information exceeds the second preset threshold, and mark the data information of the project as abnormal construction data.

[0069] In this embodiment, the abnormal construction data is located based on the four-dimensional BIM model, and the corresponding model area to be corrected and the construction stage to be corrected are identified, that is, the construction stage of the project and data information (that is, the corresponding area) corresponding to the abnormal construction data is re-determined, so as to obtain the simulated construction data corresponding to the model area to be corrected and the construction stage to be corrected in the four-dimensional BIM model as abnormal comparison data. For example, in the actual construction data, area A and area C are in the construction stage of structural construction, and area B is in the construction stage of foundation construction. However, due to clustering, area B is planned as the overall construction stage of structural construction, resulting in the first comparison of the project and data information with area B are also the project and data information in the construction stage of structural construction, resulting in different comparisons of construction data in different construction stages, resulting in large error information, that is, the construction data of area B is divided into abnormal construction data, so the four-dimensional BIM model is used to re-determine the project and data information corresponding to area B and its actual construction stage, and obtain the simulated construction data of area B in the foundation construction stage, which is marked as abnormal comparison data.

[0070] As a preferred solution of this embodiment, it also includes:

[0071] If there is no data information of any project exceeding the second preset threshold, the target marine project is inspected again according to the preset inspection route of the target marine project.

[0072] In this embodiment, if there is no data information of any project that exceeds the second preset threshold, it means that the construction stages of various areas of the actual target marine engineering are consistent and unified, so there is no need to perform a second comparison, and the target marine engineering can be continuously re-inspected according to the preset inspection route of the target marine engineering.

[0073] Step S105: Perform a second comparison between the abnormal comparison data and the abnormal construction data, mark and warn the items corresponding to the data information exceeding the first preset threshold, and realize construction monitoring of the target marine engineering.

[0074] As a preferred solution of this embodiment, the abnormal comparison data and the abnormal construction data are compared for the second time, and the items corresponding to the data information exceeding the first preset threshold are marked and warned to realize the construction monitoring of the target marine engineering, which specifically includes:

[0075] A second comparison is performed on the abnormal comparison data and the abnormal construction data to determine whether the data information of the same project between the abnormal comparison data and the abnormal construction data exceeds a first preset threshold; if there is at least one project whose data information exceeds the first preset threshold, the project corresponding to the data information exceeding the first preset threshold is marked and warned; if there is no project whose data information exceeds the first preset threshold, feedback that the target marine project is under normal construction is generated and displayed.

[0076] In this embodiment, a second comparison is performed between the abnormal comparison data and the abnormal construction data, so that it can be determined whether the data information of the same project between the abnormal comparison data and the abnormal construction data exceeds the first preset threshold. If there is at least one project whose data information exceeds the first preset threshold, it means that there is a construction deviation in the project in this area at this stage, which requires manual intervention and continuous monitoring. If there is no project whose data information exceeds the first preset threshold, it means that the current target marine project is in a normal construction stage and no intervention is required. Among them, the first preset threshold can be set according to the actual situation.

[0077] It should be noted that the items in the construction data may include, but are not limited to, construction permits and approvals, review of construction drawings and documents, procurement of construction equipment and materials, site clearing and leveling, construction of construction roads and temporary facilities, setting up of construction fences and safety facilities, access to construction water and electricity, foundation treatment and reinforcement, foundation excavation, laying of foundation cushions, foundation concrete pouring or pile foundation construction, steel bar binding and formwork installation, concrete pouring, installation and welding of steel structures, construction of walls and floor slabs, exterior wall construction (including masonry, curtain wall or prefabricated panel installation), roof structure and waterproofing layer construction, door and window installation, wiring and equipment installation of electrical systems, pipe installation of water supply and drainage systems, installation of HVAC systems, installation of fire protection systems, decoration of interior walls and floors, installation of ceilings and lighting systems, installation of interior partitions and furniture, installation of exterior lighting and signs, testing of building management systems, commissioning of electrical and mechanical systems, testing of safety systems, inspection and acceptance of construction quality, compilation and submission of construction documents, repair of construction defects, etc. The data information corresponding to different projects may be different. For example, the data information corresponding to the steel structure installation and welding projects include the steel structure material, installation positioning, welding standards and strength data, etc., while the data information corresponding to the pipeline installation projects of the water supply and drainage system may be pipeline material parameters and installation location data, etc. In addition, the data information corresponding to different projects can also be set according to different marine engineering construction facilities.

[0078] Implementing the above embodiments has the following effects:

[0079] The technical solution of the present invention generates a four-dimensional BIM model by combining the generated three-dimensional BIM model with the construction schedule, so that different projects, models, etc. in the four-dimensional BIM model can be simulated based on the same time or construction stage, and the simulated construction data corresponding to each construction stage can be obtained. At the same time, it can also obtain real-time inspection data based on the preset inspection route of the target marine engineering, thereby generating real-time construction data of the current target marine engineering, and determining the actual construction stage of the entire corresponding to the current target marine engineering. Finally, a first comparison is performed with the simulated construction data in the four-dimensional BIM model to determine the presence of abnormal data, thereby avoiding the situation in which the construction progress of the same marine engineering structure is not completely different due to the different progress and construction efficiency of different construction teams in actual construction, reducing the user's monitoring workload and complexity, so as to realize a second comparison of the abnormal comparison data and the abnormal construction data, and at the same time, the project corresponding to the data information exceeding the first preset threshold is marked and warned, thereby achieving more efficient and higher-precision marine engineering monitoring, and also improving the user's use experience.
