BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0018] 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.

[0019] The present invention provides Figure 1A method for space planning in a prefabricated substation based on a BIM model is shown, comprising the following steps: Step 1: Obtain the 3D BIM model of the substation prefabricated building; Step 2: Based on the BIM model, conduct a digital analysis of the activity space of the construction equipment in the substation, and use the space utilization algorithm to calculate the optimal activity range required by the equipment during the construction process; Step 3: Use the space utilization algorithm to optimize the number, model and configuration of construction equipment and determine its optimal layout and travel path in combination with the specific task requirements and equipment characteristics during the construction process; Step 4: Generate the installation plan and construction path planning of the construction equipment, and dynamically adjust and optimize according to the preset construction tasks; Step 5: Schedule and manage construction equipment based on the optimized construction plan, and provide real-time feedback to monitor construction progress and adjust the investment of construction resources.

[0020] Through the space utilization algorithm based on the BIM model, the optimization of equipment investment, activity range and path in the construction of substation prefabricated buildings is achieved. This technology can intelligently calculate the optimal number and model of equipment, optimize the activity range and travel path of equipment, reduce equipment redundancy and conflict, improve construction efficiency, reduce construction costs, and ensure the controllability of construction progress, quality and safety through real-time feedback and dynamic adjustment, significantly improving the utilization rate of construction resources and the overall construction management level.

[0021] Among them, the three-dimensional BIM model of step 1 includes the spatial layout of each equipment in the substation, the activity path of the construction equipment and the equipment size information.

[0022] The specific steps of step 1 include: Step 1.1: Obtain the 2D architectural design drawings of the substation, including but not limited to plan, elevation and section drawings, and convert them into a 3D BIM model; Step 1.2: Based on the equipment layout and installation requirements in the design drawings, the electrical equipment in the substation, including but not limited to transformers, switchgear and distribution equipment, are modeled in the 3D BIM model according to the design requirements; Step 1.3: Extract the building structure, equipment installation points, pipelines, wiring and air conditioning system from the drawings and integrate them into the 3D BIM model; Step 1.4: Obtain the dimensions, performance parameters and activity range data of the construction equipment from the construction equipment supplier and the project management team, and set them up as a parametric model in the 3D BIM model.

[0023] The digital analysis in step 2 includes equipment activity space demand analysis, spatial conflict detection and optimization, construction area space division, and simulation and visualization analysis.

[0024] The space utilization algorithm in step 2 specifically includes the following steps: Obtain equipment size and working scope. The BIM model provides the size and volume of each equipment and the minimum space required for movement during construction. Through the device volume V 设备 And the minimum activity space V 活动 Calculate the space utilization U using the following formula: ; By optimizing space utilization, the optimal range of activity required by the equipment can be obtained. The optimal range of activity refers to the spatial area where construction equipment can operate freely and perform tasks on the construction site. This area not only takes into account the size and operating range of the equipment, but also the safety distance of the surrounding environment, coordination between equipment, and mutual interference of other construction resources (such as personnel, materials, etc.). The goal of the optimal range of activity is to maximize the equipment's work efficiency while avoiding conflicts between equipment and equipment, and between equipment and the construction environment. When calculating the optimal range of activity, the space utilization algorithm needs to determine the most suitable activity area based on equipment size, task requirements and environmental constraints. This calculation focuses on space allocation, the scope of equipment use and the relationship between equipment and surrounding space to ensure maximum utilization of space during construction.

[0025] The space utilization algorithm in step 3 includes: Combined with the needs of the construction task, the optimal number of each type of equipment is determined. The quantitative optimization of equipment is carried out by minimizing an objective function, and its formula is: , where C i is the space occupied by the i-th type of equipment, N i is the number of equipment of type i, T 施工 For the construction time, by optimizing N i To maximize space utilization; According to the optimization results of the number of devices, the activity path planning of the equipment is carried out. The planning goal of the equipment path is to minimize the total moving distance of the equipment. The path formula is: , where D 路径i is the moving path length of the i-th device.

[0026] Path planning refers to determining the optimal route for construction equipment to travel from one location to another. Path planning not only considers the equipment's driving path on the construction site, but also factors such as traffic flow within the construction site, interactions between equipment, obstacles, construction progress, and safety. Its goal is to plan an efficient and conflict-free path to reduce equipment driving distances, avoid collisions between equipment, and improve construction progress. During the path planning process, the space utilization algorithm focuses on evaluating the relationship between the equipment's driving path and the environment, ensuring that the equipment can move along the shortest and conflict-free path while avoiding obstacles and conflicts with other equipment. In some cases, path planning also needs to be adjusted dynamically to cope with real-time changing conditions at the construction site.

[0027] The optimal range of movement algorithm focuses on the working area that the equipment can cover within the construction site, ensuring that the equipment can fully operate in space without interfering with other equipment or the construction environment. Its core is the rational allocation and utilization of space; the path planning algorithm focuses on the coordination of the equipment's movement trajectory and the environment, ensuring that the equipment can reach its destination safely and efficiently, avoiding path conflicts, equipment congestion or unnecessary path waste. Its focus is on how to find the most suitable route and optimize the driving distance; therefore, the two algorithms have different focuses: the range of movement optimization focuses more on spatial layout and space utilization, while the path planning optimization focuses on the optimal selection and dynamic adjustment of the equipment's route. By using these two algorithms respectively, the equipment's working efficiency, the utilization of construction space, and the control efficiency of construction progress can be maximized.

[0028] Among them, the dynamic adjustment and optimization in step 4 includes adjusting the activity range and path planning of construction equipment according to the real-time data of construction progress, personnel flow, and equipment operation status, and adjusting the activity range and path planning of construction equipment through real-time data feedback to adapt to the actual changes of the construction site. Its main purpose is to timely adjust the task execution plan and path of construction equipment according to the dynamic changes of construction progress, personnel flow, equipment operation status, etc., to ensure the efficiency, safety and smooth progress of the construction process.

[0029] Among them, the installation plan and construction path planning in step 4 are displayed in real time through the BIM model visualization tool, and construction personnel and managers can perform intuitive operations and decisions based on the visualization interface.

[0030] Among them, the scheduling management in step 5 includes construction equipment scheduling and construction resource scheduling. Construction equipment scheduling includes equipment task allocation, equipment scheduling priority, and equipment resource coordination. Based on the construction task plan and equipment availability, the scheduling system automatically assigns specific tasks to each device. For example, in the construction plan, it is specified that certain cranes need to complete equipment lifting work in a specific time period and area. The scheduling system will assign the corresponding equipment to operate according to the task requirements; according to the task priority and equipment workload, the scheduling system can automatically adjust the priority of the equipment. For example, when some tasks are of high urgency, the system will give priority to scheduling necessary equipment to ensure the smooth progress of high-priority tasks; on-site usually requires multiple devices to work together, and the scheduling management will ensure that the collaborative work between equipment does not cause Conflicts can be avoided, and the order of operations can be reasonably arranged according to the working area, load, operating space and other requirements of the equipment. Construction resource scheduling includes personnel scheduling and management, construction materials and equipment scheduling. According to the construction progress, task requirements and construction period, the scheduling system will make reasonable arrangements for the construction personnel. For example, certain tasks requiring high professional skills may require specific operators, while ordinary tasks can be completed by other personnel. Through dynamic personnel scheduling, personnel can be deployed according to actual needs to ensure the smooth completion of construction tasks. In addition to equipment and personnel, material scheduling in the construction process is also crucial. Scheduling management needs to ensure that construction materials are in place in a timely manner and coordinate the reasonable coordination of equipment and materials. For example, the work of a certain equipment requires specific material support, and the scheduling system will ensure the timely supply of materials according to the task progress.

[0031] Among them, the real-time feedback in step 5 is the real-time feedback of various data and information in the construction site and equipment operation to the project management system, which is used by management personnel to understand the construction progress, equipment status, and resource usage. The real-time feedback includes construction progress feedback, equipment status feedback, resource utilization feedback, task execution deviation feedback, construction site environment feedback, and construction safety feedback.

[0032] Construction progress feedback refers to comparing the planned progress with the actual progress, and promptly displaying progress deviations for adjustment and optimization. It helps project managers determine whether there are construction delays and whether resources or construction strategies need to be adjusted. Feedback content includes real-time display of task completion status, progress delays, completed workload, unfinished workload, etc. Feedback forms include progress bars, construction progress reports, and deviation warnings. In the construction progress management system, the actual completion status of each task and the gap between the planned progress are displayed in the form of Gantt charts or progress bars. The progress of various tasks and sub-tasks is fed back to managers in the form of charts, pie charts, bar charts, etc., clarifying which tasks have been completed and which tasks are behind schedule. When the gap between the actual progress and the planned progress exceeds a certain threshold, the system will automatically trigger a deviation alarm and alert the project manager.

[0033] Equipment status feedback includes information such as the equipment's operating conditions, usage efficiency, and fault status. It can help project managers promptly understand whether the equipment can perform tasks as planned and whether it needs to be repaired or replaced. The feedback content includes the equipment's current status (such as running, idle, faulty, etc.), equipment load, remaining working time, equipment failure, and troubleshooting time.

[0034] Resource utilization feedback involves real-time monitoring of the use of construction resources (including equipment, personnel, and materials) to ensure the rational allocation and efficient use of resources. The feedback content includes personnel's work situation (such as working hours, task completion status), material usage (such as inventory, supply status), equipment workload, etc.

[0035] Task execution deviation feedback refers to the system monitoring the quality and quantity deviations of task completion during the construction process, and feeding back this information to managers to help them adjust construction resources or processes. The feedback content includes the quality of task completion, actual workload, deviation type (such as workload deviation, time deviation, quality deviation), etc.

[0036] Environmental conditions at the construction site (such as weather, temperature, humidity, etc.) will also affect the construction progress and resource allocation. Real-time feedback of environmental data can help construction managers reasonably adjust construction plans and resource allocation. The feedback content includes climate changes (such as temperature, humidity, rainfall, wind speed, etc.) and other environmental factors that affect construction.

[0037] Safety management is also an important part of construction management. Safety issues at the construction site need to be monitored and fed back in real time to ensure the safety of construction workers. The feedback content includes safety hazards, accidents, dangerous areas, etc. at the construction site.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
