Description

Technical Field

[0001] The present invention relates to the technical field of construction site layout, and in particular to a project intelligent management method based on digital twins. Background Art

[0002] With the continuous development of the times, more and more requirements are placed on the construction environment of the construction site. Not only higher requirements are put forward for the management of noise, light pollution, dust pollution, etc. at the construction site, but also requirements are put forward for the construction unit in terms of personnel, machines, materials, methods, and environment. At the same time, the construction unit also needs to minimize energy waste and cost expenditure during the construction process.

[0003] The traditional construction site layout method is as follows:

[0004] 1. Choice of temporary office and living area: mainly divided into arrangement within the red line and off-site rental. The arrangement within the red line needs to be combined with the surplus of on-site space. If the surplus is large, the implementation is more feasible, otherwise it is more difficult. Compared with the implementation within the red line, off-site rental requires additional application and increases costs, but the advantage is that it has less impact on on-site construction.

[0005] 2. Site layout of the construction site operation area: According to the building height and the key parts of material lifting, the optimal vertical transportation equipment is manually analyzed, and the material yard stacking position is considered in combination with the location of the vertical transportation equipment, and finally a plane site layout diagram is formed to guide the on-site implementation; inadequate consideration (such as the location of the tower crane and the selection of the tower crane model) will directly affect the construction period and equipment rental time, and will also lead to construction inconvenience and increase time cost and expenses;

[0006] The traditional construction site layout method has the following problems:

[0007] 1. Influence of human factors: Traditional construction site layout methods often rely on human experience, without more scientific judgment, and will not be evaluated in combination with local hydrological and meteorological factors, which may lead to energy waste (such as: the improper location of temporary office and living areas increases the use of air conditioners, thereby increasing electricity consumption). Since each project location and working conditions are different, the traditional construction site layout method cannot quickly obtain a scientific and reasonable site layout plan suitable for different projects. In the subsequent implementation process, unreasonable layouts are found and then modified, which increases time costs and expenses, and causes more energy consumption and pollution to the internal and external environments of the construction site.

[0008] 2. Information islands: Traditional construction site layout methods often lack the collection and sharing of real-time data, resulting in information opacity, affecting decision-making efficiency, and the existence of information islands.

[0009] 3. Weak response capability to emergencies: Traditional construction site layout methods are difficult to quickly adjust to emergencies (such as changes in Party A's needs and climate change), and the response capability is insufficient;

[0010] 4. Insufficient visualization: The traditional construction site layout method lacks three-dimensional visualization tools, resulting in an incomplete understanding of the overall situation and insufficient consideration of the construction site layout plan (such as the location of the tower crane and the selection of the tower crane model, which will directly affect the construction period and equipment rental time). It will also lead to construction inconvenience and increased time and expenses; it cannot create a comfortable and green construction site working environment, and cannot respond to the pollution generated on site in a targeted and timely manner. Summary of the invention

[0011] The present invention aims to provide an intelligent project management method based on digital twins to solve the problems that traditional construction site layout methods are greatly affected by human factors, have information islands, have weak response capabilities to emergencies, and lack visualization.

[0072] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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.

[0073] Example 1

[0074] like Figure 1-Figure 4 As shown, this embodiment proposes a project intelligent management method based on digital twins, including the following steps:

[0075] S1: Import the historical data of all built projects into the digital twin platform, and extract the historical data of built projects around the new project according to the location of the new project; analyze the extracted historical data of the built projects, diagnose the problems and improvement space in the built projects, optimize the built projects, and obtain the optimization plan for the built projects around the new project.

[0076] Among them, the digital twin platform can adopt Siemens MindSphere, PTC ThingWorx, Microsoft Azure Digital Twins, etc.

[0077] Historical data includes basic project information (name, number, type, etc.), cost data (material costs, labor costs, equipment costs, etc.), time data (planned construction period, actual construction period, etc.), resource usage data (human resource usage, material usage, equipment usage, etc.), and quality data (quality inspection report, rework rate, etc.).

[0078] There are two sources of historical data for all built projects:

[0079] 1. Directly connect the original similar platform data to this digital twin platform;

[0080] 2. Deploy sensor networks for existing projects and collect relevant data of existing projects through sensor networks. Sensor networks include sensors for energy monitoring, load management monitoring, air smart sensors, noise monitoring sensors, vibration sensors, temperature and humidity sensors, structural health monitoring sensors, etc.

[0081] Diagnose problems and room for improvement in existing projects, including material loss, time loss, human resource loss, etc.

[0082] A spatial coordinate system is established in the digital twin platform, the distance between the components of the existing projects around the new project is calculated, the area of ​​each area of ​​the site is calculated, the volume of earthwork or other materials is estimated, the safety distance is calculated, a resource scheduling model is established, the working time is calculated, and collision detection is performed, so as to facilitate the analysis of the extracted historical data of the existing projects, facilitate the diagnosis of problems and improvement space in the existing projects, and obtain optimization plans for the existing projects around the new project.

[0083] (1) Space coordinate system:

[0084] It is used to construct a three-dimensional coordinate system for the construction site, usually expressed as: P(x, y, z), where x, y, and z represent the position of the site in three dimensions respectively.

[0085] (2) Distance calculation:

[0086] It is often necessary to calculate the distance between various locations on a construction site. For example, the distance d between point A (x1, y1, z1) and point B (x2, y2, z2) can be calculated using the following formula:

[0087]

[0088] (3) Area calculation:

[0089] When arranging the venue, it is necessary to calculate the area of ​​different areas. For example, the area A of the rectangular area can be calculated using the following formula:

[0090] A=l×w

[0091] Where l is the length of the field and w is the width of the field.

[0092] For irregular areas, you can use the integration method or divide it into multiple regular shapes for calculation.

[0093] (4) Volume calculation:

[0094] When you need to estimate the volume of earthwork or other materials, you can use the following formula:

[0095] V=A×h

[0096] Where A is the area of ​​the cross section of the earth or other material, and h is the height of the earth or other material.

[0097] (5) Calculation of safety distance:

[0098] Construction sites often require safety distances. For example, set a safety distance between workers and machinery. s :

[0099] d s = k × D

[0100] Where k is the safety factor and D is the operating radius of the equipment or worker.

[0101] (6) Establish resource scheduling model:

[0102] In construction projects, the scheduling of resources usually follows an optimization algorithm, such as linear programming. Assuming that the total cost C needs to be minimized, it can be expressed as:

[0103]

[0104] Among them, c i is the cost of the ith resource, and x is the usage of the ith resource.

[0105] (7) Calculation of working hours:

[0106] The time forecast of the construction task can be calculated by the weighted average method:

[0107]

[0108] Among them, O is the optimistic time, M is the most likely time, and P is the pessimistic time.

[0109] (8) Perform collision detection:

[0110] Maintaining safety is critical on construction sites, and collision detection algorithms are often needed to avoid collisions between equipment and personnel.

[0111] The plane can be represented as: A i *x+B i *y+C i *z+D=0, that is, N i *P+D=0, where N i =(A i ,B i ,C i ) is the normal vector of the plane, and the normal vector of the plane is defined to point to the front of the plane. P = (x, y, z) is any point in the plane, and D is the distance from the plane to the origin. When determining the positional relationship between point M and the plane, the coordinates of point M can be substituted into the calculation of N i *M+D, if N i *M+D>0, indicating that point M is in front of the plane. If N i *M+D<0, it means that point M is behind the plane. When judging the positional relationship between point M and the convex polyhedron (judging whether point M is inside the convex polyhedron), if point M has N for all faces of the convex polyhedron i *M+D<0, then a collision occurs if point M has N for at least one face of the convex polyhedron i *M+D>0, then no collision occurs.

[0112] S2: Use big data technology to create new projects in real scenarios through the digital twin platform.

[0113] Acquiring data from real scenarios includes establishing a data collection layer, a data transmission layer, a data storage and processing layer, and a digital twin modeling layer, and establishing connections between them in sequence;

[0114] Building the data collection layer includes:

[0115] Arrange sensor network: Set up various sensors, such as temperature sensors, humidity sensors, displacement sensors, cameras, etc., to collect environmental data in real time.

[0116] Conduct drone monitoring: Use drones to conduct on-site monitoring, take aerial photos of large areas, and provide high-definition images and videos.

[0117] Establishing the data transmission layer includes:

[0118] Establish a communication network: Use high-speed communication technologies such as 5G and Wi-Fi to connect the sensor network to the communication network to ensure real-time transmission of data to the cloud or local server.

[0119] Perform edge computing: Set up edge devices on site to process some data, reduce the burden on the cloud, and improve response speed.

[0120] Building the data storage and processing layer includes:

[0121] Establish cloud storage: store all collected data in the cloud platform for remote access and analysis;

[0122] Perform data integration: Use data processing techniques to integrate data from different sources, clean and pre-process data.

[0123] Building the digital twin modeling layer includes:

[0124] Conduct 3D modeling: Use BIM (Building Information Modeling) technology to build a 3D model of the construction site, including building structure, equipment, and site layout.

[0125] Conduct physical modeling and simulation: Incorporate actual site data to continuously update digital models and conduct enhanced simulation of physical properties.

[0127] Step S3 specifically includes:

[0128] S3-01: Arrange office and living areas;

[0129] Analyze and determine the open space or non-main buildings within the red line site through big data intelligent analysis software (such as real-time closed area 3D modeling based on the Beidou satellite positioning system, etc.), and then obtain various temporary construction plans for office and living areas through BIM technology in accordance with the enterprise's standardized temporary construction standards;

[0130] Combined with local hydrological and meteorological information, various temporary construction plans are analyzed for lighting, the natural lighting conditions of the room are evaluated, and the temperature changes and heat distribution in the room are predicted;

[0131] According to the temperature changes and heat distribution in the room, the temporary construction plan is optimized to try to keep the temperature in the room within the suitable temperature range for human body;

[0132] Determine 3-10 optimized temporary construction plans, and simultaneously generate the plan drawings, 3D renderings, estimated construction costs, and operation and maintenance costs of the plans;

[0133] After the decision of the project leadership, a temporary construction plan is selected, and construction drawings (including plan view, axonometric view, and clear insulation and thickening areas) and material usage tables are exported;

[0134] Carry out construction according to the construction drawings, monitor the construction process, provide timely feedback, and continuously optimize and adjust the construction process.

[0135] When the off-site land leasing method is adopted, firstly, the open space close to the construction site is analyzed according to the satellite data, and then according to the optimization scheme obtained in step S1, various temporary construction schemes for office and living areas are obtained and optimized.

[0136] Among them, the non-main buildings refer to foyers, auxiliary rooms, etc.

[0137] In the process of obtaining temporary construction plans through BIM technology, standardized family library models can be used to achieve the purpose of rapid design and subsequent standardized construction.

[0138] The temporary construction plan obtained through BIM technology can directly provide the material consumption of the temporary construction plan, and provide accurate construction costs based on the operating cost situation.

[0139] Optimization of temporary construction plans includes: optimizing building structure design, building orientation, window location and size, and building materials. For example, for directions with stronger light, insulation measures can be added in that direction of the building to reduce subsequent air-conditioning energy consumption.

[0140] S3-02: Arrange the construction site;

[0141] First, create a project BIM model, including the project implementation model, the surrounding terrain of the site, and the building model. Then, according to the building conditions, automatically generate a variety of tower crane layout models, and analyze the domestic lifting load requirements combined with the tower crane model. The project decision-maker determines the preliminary vertical mechanical transportation plan based on the analysis data. Then, according to the site conditions, formulate a temporary construction access road plan through big data intelligent analysis software, and then determine the temporary storage yard plan.

[0142] Next, the equipment rental costs for each plan are derived, and the time for installing and dismantling the tower crane is provided to facilitate the control of the tower crane rental costs and assist in optimizing the construction schedule; the material setting costs and the maximum amount of material yard stacking for each plan are derived to provide a basis for the on-site material supply plan, and even a material delivery plan can be provided; the power supply requirements for the construction site equipment of each plan are derived, and temporary power distribution lines on the construction site are reasonably formulated to avoid energy waste.

[0143] Select a construction plan, monitor the construction process, provide timely feedback, and continuously optimize and adjust the construction process.

[0144] The access road route can be selected as a circular route or a single-line route according to the working conditions of the construction site. Among them, the single-line route requires a vehicle turning area.

[0145] S3-03: Arrange the garden-style construction site;

The barrier formed by landscape vegetation can reduce the impact of noise pollution in the site on the outside world, and use vegetation to collect dust, so as to achieve a combination of permanent and temporary, create an environment in the construction site in advance, and improve the construction completion schedule.

[0147] S4: Implement monitoring and feedback mechanisms to provide a basis for adjusting the layout of new projects and provide historical data for subsequent new projects.

[0151] Deploy drones to patrol and photograph sites, acquiring high-resolution images and videos.

[0152] For data transfer:

[0153] The collected data is transmitted to the central database in real time via wireless networks (such as 5G, Wi-Fi), ensuring the reliability and timeliness of the data for further analysis.

[0154] Perform real-time analysis:
