Description

Technical Field

[0001] The present invention relates to the technical field of digital installation, and particularly to a digital management method for mechanical installation based on BIM digital modeling. Background Art

[0002] Traditional mechanical installation management mostly relies on manual experience and static planning, and it is difficult to dynamically coordinate the construction progress and resource allocation in multiple regions. It often leads to low efficiency and resource waste due to path conflicts and unreasonable priorities. Especially in complex projects, problems such as the intersection of equipment transportation paths and the spatial coupling of construction areas are prone to cause process conflicts. The existing methods lack a scientific quantification of installation priorities and a dynamic adjustment mechanism, and it is difficult to accurately predict the installation progress and optimize the equipment start-stop strategy, resulting in high energy consumption and poor coordination.

[0003] With the popularization of BIM technology, its application in construction visualization and collision detection has been relatively mature. However, there are still deficiencies in how to deeply combine the BIM model to achieve dynamic intelligent management of mechanical installation.

[0015] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. Embodiment 1

[0016] Referring to Figure 1 as shown, this embodiment proposes a digital management method for mechanical installation based on BIM digital modeling, including: Perform 3D modeling on the mechanical installation space based on the BIM model, and divide the installation space into several independent construction areas; Achieve precise division of construction areas through BIM 3D modeling, avoid the risk of equipment collision caused by spatial overlap in traditional plane planning, and improve construction safety; provide a structured data basis for subsequent dynamic priority adjustment; Determine the installation priority of each construction area according to the location attributes of each construction area and the equipment transportation path; Scientifically quantify the initial priority by combining the transportation path and location attributes, solve the blindness problem of traditional empirical scheduling, significantly reduce the probability of path conflict; improve construction efficiency by reasonably allocating resources and reducing the idle waiting time of equipment; Obtain the current installation progress status of each construction area; Real-time progress monitoring supports a dynamic feedback mechanism, avoids resource misallocation caused by information lag, and improves the transparency of the construction status; combined with the BIM model visualization interface, multi-department collaborative management is realized, communication costs are effectively reduced, and installation tasks are ensured to be updated synchronously with the actual progress; Call historical project data, and combine the simulation analysis of the BIM model to predict the mechanical installation completion volume in the future period; Based on the prediction model of historical data and BIM simulation, significantly improve the prediction accuracy of the installation volume, avoid resource waste caused by manual estimation deviation; dynamic prediction supports risk anticipation, adjusts the construction plan in advance, and reduces the risk of construction period delay; Based on the predicted mechanical installation completion volume, determine the target construction areas where equipment installation needs to be carried out; Through data-driven screening of target areas, achieve focused resource investment, significantly improve the construction efficiency of key areas; avoid premature occupation of equipment in non-key areas, reduce resource idleness problems, and ensure the optimal matching of equipment and tasks; Send installation instructions to the BIM collaborative management platform of the target construction area, activate the construction equipment in the target area and start the installation process; Send standby instructions to the BIM collaborative management platform of non-target construction areas, and adjust the construction equipment in non-target areas to a low-energy standby state.

[0017] Based on the accurate instruction delivery of the BIM platform, achieve one-key start of equipment and automated process control, greatly reduce manual operation errors; centrally activate the equipment in the target area, significantly improve equipment utilization rate, and support remote collaborative operations, reducing the complexity of on-site management. The intelligent standby strategy for equipment in non-target areas effectively reduces the overall energy consumption, meeting the requirements of green construction; extend the service life of equipment through the low-power mode, reduce maintenance costs, and avoid mechanical wear caused by frequent start and stop, ensuring construction continuity. Embodiment 2

[0018] Referring to Figure 2 as shown, based on Embodiment 1, this embodiment further proposes to determine the installation priority of each area according to the location attributes of each construction area and the equipment transportation path, specifically including: Based on the location attributes of each construction area, determine the equipment transportation path intersection relationship between each construction area within the mechanical installation space; Referring to Figure 3 as shown, the specific method steps are as follows: Based on the location attributes of the construction area, determine at least one transportation path from the entrance of the mechanical installation space to the location of the construction area, denoted as the equipment transportation path of the construction area; Denote each other construction area passed by each equipment transportation path of the construction area as the equipment transportation intersection area of the construction area; Summarize all the equipment transportation paths of the construction area to obtain the equipment transportation path set of the construction area; Summarize all the equipment transportation intersection areas of the construction area to obtain the equipment transportation intersection area set of the construction area; Summarize the equipment area set that takes the construction area as the equipment transportation intersection area to obtain the transportation center area set of the construction area; The equipment transportation path sets, equipment transportation intersection area sets, and transportation center area sets of all construction areas constitute the equipment transportation path intersection relationship between each construction area within the mechanical installation space.

[0019] For example, there are two transportation paths from the entrance of the mechanical installation space to construction area A, namely B→C→A and D→C→A, then both B→C→A and D→C→A are the equipment transportation paths of construction area A; Based on the fact that both B→C→A and D→C→A are the equipment transportation paths of construction area A, then construction areas B, C, and D involved in B→C→A and D→C→A are all the equipment transportation intersection areas of construction area A; Summarize the equipment transportation paths of construction area A, that is, the set composed of B→C→A and D→C→A is the equipment transportation path set of construction area A; Summarize the equipment transportation intersection areas of construction area A, that is, the set composed of construction areas B, C, and D is the equipment transportation intersection area set of construction area A; Since B→C and D→C are also the equipment transportation paths of construction area C, then construction area C also takes construction areas B and D as the equipment transportation intersection areas, so at least construction areas A and C are included in the transportation center area set of construction areas B and D.

[0020] Based on the cross-relationship of equipment transportation paths between construction areas, determine the transportation center index for each construction area; Specifically, referring to Figure 4 as shown, the transportation center index of the construction area is determined by the following steps: Based on the attributes of the equipment to be installed in the construction area, determine the initial importance index of the construction area. When there is no forward or backward association between the equipment in each area, usually the initial importance index of all construction areas is set to , when there is a forward or backward association between the equipment in each area, the initial importance index of the construction area ranked ahead is set higher than that of the construction area ranked behind; Based on the basic theory of the Pagerank algorithm, combined with the initial importance index of each construction area, construct a transportation center index evaluation formula; Based on the transportation center index evaluation formula, perform at least one iterative calculation to obtain the transportation center index of the construction area; Among them, the transportation center index evaluation formula is specifically:

[0021] In the formula, is the transportation center index calculated for the i-th construction area in the k-th iteration, is the damping coefficient, is the total number of construction areas, is the set of transportation center areas of the i-th construction area, is the j-th element in the set of transportation center areas of the i-th construction area, is the total number of elements in the set of equipment transportation paths corresponding to j, is the number of elements including the i-th construction area in the set of equipment transportation paths corresponding to j, is the transportation center index calculated for j in the (k - 1)-th iteration; Among them, is the initial importance index of the i-th construction area.

[0022] In the traditional Pagerank algorithm, the out-link probability of each node to its out-link nodes is the same. However, in the analysis of regional centrality in this solution, this analysis method is not applicable. For example, in the relationship listed above, construction area A is the transportation center area of construction area C. Since construction area A needs to pass through construction area C regardless of which equipment transportation path it takes, at this time, construction area C, as the equipment transportation intersection area of construction area A, is an inevitable passing area of construction area A. Then the probability of the association of construction area A to construction area C is 100%. Therefore, based on the basic theory of the Pagerank algorithm in this solution, the formula of the Pagerank algorithm is specifically improved, using " ”As the correlation probability between the construction area and the equipment transportation crossing area, it realizes the high-precision identification and calculation of the transportation center index of the construction area.

[0023] By dynamically setting the initial importance index by combining the relevance of equipment attributes and constructing a transportation centrality evaluation model based on the improved Pagerank algorithm, comprehensively considering the path crossing relationship and equipment dependency logic, accurately quantify the influence of the transportation network in the construction area. Optimize the transportation center index through iterative calculation, adaptively identify high-frequency crossing nodes and key path-dependent areas, realize dynamic adjustment of resource priorities, effectively reduce the risk of transportation path conflicts, reduce equipment waiting and detour time, and at the same time ensure the continuity of the front and back processes, significantly improve the multi-region collaborative construction efficiency and the global coordination of mechanical installation, and provide scientific decision-making support for resource optimization allocation in complex scenarios.

[0024] According to the ascending order of the transportation center index, the additional installation priorities of each construction area are arranged in turn.

[0025] By systematically analyzing the equipment transportation paths in the construction area and their crossing areas, accurately construct a path topology relationship network for the mechanical installation space, and effectively solve the problem of low transportation efficiency caused by path conflicts in traditional methods. Dynamically identify key transportation nodes based on the path crossing relationship, such as construction areas frequently traversed by paths in other areas, predict potential congestion risks and optimize transportation routes in advance, reduce equipment waiting and detour time; at the same time, by summarizing the transportation center area set, provide data support for priority evaluation, ensure that resources are preferentially allocated to areas with strong path dependence, avoid construction interference and resource waste caused by path crossing, and overall improve the coordination and transportation efficiency of mechanical installation. Example 3

[0026] Refer to Figure 5 As shown, on the basis of Example 2, this example further proposes to call historical project data and combine the simulation analysis of the BIM model to predict the mechanical installation completion volume in the future period, specifically including: Taking a day as a cycle, call historical project data to determine the historical mechanical installation completion volume in each cycle; Set a simulation analysis data volume, denoted as X, and take the historical mechanical installation completion volume in the X cycles closest to the current moment as the analysis data; Using the analysis data as a sample, predict the mechanical installation completion volume in the next cycle.

[0027] Specifically, the mechanical installation completion volume in the next cycle can be represented by the average value of the analyzed data or calculated by linearly regressing the historical mechanical installation completion volume in X cycles to analyze the linear change trend. The specific calculation steps for calculating by linearly regressing the historical mechanical installation completion volume in X cycles are as follows: Number the historical mechanical installation completion volumes in X cycles in order from the farthest to the nearest in time; Taking the historical mechanical installation completion volume in the cycle as the dependent variable and the number as the independent variable, construct a unary linear regression equation between the historical mechanical installation completion volume and the number; Substitute X + 1 into the unary linear regression equation between the historical mechanical installation completion volume and the number to obtain the mechanical installation completion volume in the next cycle.

[0028] By dynamically collecting historical installation data on a daily cycle and combining the recent X - cycle samples for predictive analysis, the timeliness and accuracy of predicting the mechanical installation completion volume are effectively improved. Based on the rolling - updated historical data screening mechanism, old data interference is excluded, the fluctuation trend of construction efficiency is accurately captured, and dynamic adjustment of resource allocation is supported; at the same time, by predicting the installation volume in the next cycle, equipment and manpower inputs are planned in advance, avoiding resource shortages or idleness caused by inaccurate task volume estimation, significantly reducing the risk of project duration delays, providing real - time data support for construction decisions, and realizing the intelligent and forward - looking optimization of mechanical installation management.

[0029] Furthermore, in this embodiment, determining the target construction area where equipment installation needs to be carried out based on the predicted mechanical installation completion volume specifically includes: Extract the construction areas in order of the installation priority of the construction areas from high to low, and accumulate the mechanical installation task volumes extracted until the accumulated value of the mechanical installation task volumes of the extracted construction areas is greater than or equal to the predicted mechanical installation completion volume in the next cycle; Record the extracted construction area as the target construction area where equipment installation needs to be carried out.

[0030] Through the dynamic priority sorting and predicted task volume matching mechanism, the target construction area is accurately screened, ensuring that high - priority areas are allocated resources first and avoiding resource waste caused by low - priority areas occupying equipment prematurely. This method combines real - time prediction data with priority logic to achieve the dynamic balance between task volume and construction capacity, effectively focus on the critical path construction, reduce equipment idling in non - essential areas, and at the same time ensure the continuity of highly dependent processes, significantly improving resource utilization efficiency and project progress controllability, and reducing the risk of project duration delays caused by resource misallocation.

Its innovation lies in: Quantifying the regional priority based on the transportation network centrality algorithm to effectively avoid path conflicts and resource contention; Dynamically adjusting the target construction area through historical data and simulation prediction to significantly improve equipment utilization rate and installation efficiency; At the same time, accurately controlling the start and stop states of equipment based on the BIM collaborative platform, switching the equipment in non-target areas to the low-power standby mode to reduce the overall energy consumption.
