[0052] The embodiment provides a mechanical and electrical engineering resource configuration method based on spatial coupling degree. Figure 1 The flowchart of the mechanical and electrical engineering resource configuration method based on spatial coupling degree according to the embodiment of the present application is shown in Figure 1 The flowchart includes the following steps:

[0053] In step S101, based on the mapping relationship between the pre-constructed WBS task and the BIM component, the process method of each BIM component is determined, and the process bounding box of each BIM component is generated according to the process method and the three-dimensional model of the component.

[0054] Through the BIM model, a BIM space corresponding to the physical space 1:1 is established, and a progress plan with space and room as the minimum granularity is generated based on the sub-item plan.

[0055] Specifically, a mapping network of WBS task and BIM component is constructed, the room and WBS are associated by identifying the BIM component in the BIM room bounding box, a plan space column item is formed, all components within the same BIM room range are extracted with the room as the dimension, and a room task is generated.

[0056] In the whole engineering range, three-dimensional space division is performed through the BIM model, a spatial topology relationship network is established, and a standardized spatial attribute naming system is established.

[0057] Select the existing physical boundaries in the project, and divide the space in the BIM model: vertical components (such as load-bearing walls, permanent partition fences) form the vertical boundary of the space, horizontal components (such as floor slabs, etc.) divide the range of the plane partition, and dynamic components (such as movable partitions, temporary fences) define the flexible space edge. Define the category attributes of the divided rooms, which are divided into public space (transportation, processing, stacking, etc.) and construction space. A space can be a public space or a construction space. Table 1 is a rule table for naming based on space attributes according to an embodiment of the present application.

[0058] Table 1

[0059]

[0060] By identifying the space edge relationship in the BIM component, the topological relationship between spaces is automatically established. For example: the path connection between space A and space B on the same floor (the horizontal connection between space A and space B on the same floor is established through the door structure and / or other spaces), which is determined as the first relationship (ADJ); for example, the path connection between space C and space D on different floors (the vertical connection between space C and space D on different floors is established through the elevator space, etc.), which is determined as the second relationship (BH). Table 2 is a basic table of space attributes according to an embodiment of the present application.

[0061] Table 2

[0062]

[0063] Establish the space topological relationship to form the topological relationship coding rule: space ID_topological type_associated space ID (for example: B201_ADJ_B205 indicates that space B201 and B205 are spaces on the same floor and path connected; A101_ADJ_A102, A101_ADJ_A103, indicates that space A101 is a public transportation space for A102, A103). Table 3 is a topological relationship-space attribute coding table according to an embodiment of the present application, as shown in Table 3, A101 belongs to a public transportation space, and is used as a transportation space for A102, A103, and D101.

[0064] Table 3

[0065]

[0066] In some embodiments, the step S101 of generating a bounding box of each BIM component according to the three-dimensional model of the process method and the component includes:

[0067] In step S1011, a component bounding box of the BIM component is generated according to the three-dimensional model.

[0068] Step S1012, based on the process method and the component bounding box, determine the process occupied space of the BIM component.

[0069] Step S1013, based on the continuous operation process and the space constraint condition, correct the process occupied space to obtain the process bounding box of each BIM component.

[0070] Take a space or a room as the granularity of resource planning configuration, extract the BIM components in the space and the key attributes of the BIM components, and the key attributes include the elevation of the BIM component, the XYZ coordinates of the minimum coordinate system bounding box (AABB) of the BIM component, and the WBS task to which the BIM component belongs. On the one hand, the process method is selected to determine the process, and on the other hand, the physical space bounding box of the BIM component is determined.

[0071] Specifically, based on the BIM component three-dimensional model, the attributes (such as coordinates and dimensions) of the BIM component are extracted, the physical entity occupation space is established, the axis-aligned bounding box (AABB) and the oriented bounding box (OBB) of the component are generated. The covariance matrix of the triangular mesh vertex of the component is calculated, and the eigenvectors are the main axes of the OBB. Among them, the axis-aligned bounding box (AABB) is used to determine the process occupied space, and the oriented bounding box (OBB) is used for subsequent component space coupling degree analysis.

[0072] By extracting the attributes of the BIM component, combining the WBS task and the BIM mapping, the mapping of WBS and industry quota, the process method of the component is determined, and the resources (such as machinery, tools, etc.) involved are determined according to the process method used by the component. Table 4 is a WBS task-BIM component-quota ternary mapping table according to an embodiment of the present application.

[0073] Table 4

[0074]

[0075] According to the selected resource configuration type, the process of the physical bounding box of the component is expanded to form the process occupied space. It should be noted that in the present embodiment, the occupation space is established for different processes such as manufacturing, transportation, installation, detection, etc.

[0076] Define the basic process space required by each process, and form the space bounding box The space occupied by each component is represented by its axis-aligned (AABB) bounding box, which uses two pairs of diagonal point coordinates p min =(x min ,y min ,z min ) and p max =(x max ,y max ,z max) precisely describe the geometric boundary. The definition ensures that the bounding box is aligned with the global coordinate system, facilitating spatial calculations. Among them, p min , p max are diagonal coordinate points, x min , y min , z min are near point XYZ axis coordinates, x max , y max , z max are far point XYZ axis coordinates.

[0077] Different process tools (such as trolleys, cranes, ladders, mobile scaffolding, etc.) will cause differences in the space occupied by the component process. By tool size correction, the bounding box boundary needs to be expanded:

[0078]

[0079] x' min is the near point x-axis coordinate of the process occupancy bounding box after considering the tool occupancy size, x' max is the far point x-axis coordinate of the process occupancy bounding box after considering the tool occupancy size, , is the difference in the expansion of the x-axis process occupancy size. The y-axis and z-axis are expanded in the same way.

[0080] Table 5 is a tool occupancy standard table according to an embodiment of the present application. As shown in Table 5, a is the basic occupancy length without the help of occupancy tools to complete the process; b is the occupancy width without the help of occupancy tools to complete the process; h is the occupancy height without the help of occupancy tools to complete the process; A is the physical space occupancy length of the occupancy tool; B is the physical space occupancy width of the occupancy tool; H is the physical space occupancy height of the occupancy tool.

[0081] Table 5

[0082]

[0083] The occupancy space B i (P) of the process P of the component i is represented by the following formula:

[0084]

[0085] In some embodiments, step S1013 includes:

[0086] Step S201, based on the Boolean AND operation, merging the process occupancy space corresponding to the consecutive operation process, obtaining the process bounding box.

[0087] The consecutive operation needs to merge multiple process bounding boxes, and take the maximum range B process . Let the bounding box of the adjacent process of the consecutive operation be Bi , B j , which is a Boolean AND operation:

[0088]

[0089] Step S202, determine whether the process occupies the space to meet the space constraints, if not, reselect the process used utensils, to correct the process of space occupation, according to the process of space occupation after the correction of the process of bounding box.

[0090] In the case of meeting the specification requirements, the use of space utensils is affected by the general space where the BIM component is located, the physical space of the BIM component, the public space and other space attributes, for example, the finished activity scaffold is limited by the floor height T i (floor), T +1 (installation height), TTRANSPORT_[space code] (read the public transport space height related to the topological relationship ID of the space where the component is located) limit, the direction boundary of the bounding box needs to meet:

[0091]

[0092] Where M(T) is the height set of all related public spaces. If there is a case of exceeding the limit, the model of the space utensil needs to be reselected, or the use of the space utensil is not considered.

[0093] With reference to Figure 1 , after obtaining the process bounding box, step S102 is performed.

[0094] Step S102, determine the parameter value of each process parameter based on the process bounding box and the process sequence, and perform construction priority sorting of the component according to the parameter value and the weight corresponding to each process parameter, wherein the process parameter includes a space relationship parameter and a sequence relationship parameter.

[0095] According to whether the public space SP is occupied, the relationship between the process bounding boxes (whether it contains, the number of collisions, etc.), the relationship between the process bounding box and the component physical bounding box, and the number of subsequent processes, the component installation priority is calculated.

[0096] In some embodiments, the space relationship parameter includes a first process parameter, a second process parameter, a third process parameter, and a fourth process parameter, and the sequence relationship parameter includes a fifth process parameter;

[0097] The first process parameter is used to represent whether the process bounding box occupies the public space.

[0098] The first process parameter is used to represent the spatial relationship between the process occupied space and the public space, and the process priority is high when it does not occupy the public space, and the process priority is low when it occupies the public space. The first process parameter has the highest weight level.

[0099] The second process parameter is used to represent the inclusion relationship between the bounding boxes of each process.

[0100] The third process parameter is used to represent the coupling degree of the completed component and other process bounding boxes.

[0101] The third process parameter is the number of collisions between the completed component and other process bounding boxes.

[0102] The fourth process parameter is used to represent the intersection relationship between the bounding boxes of each process.

[0103] The fifth process parameter is used to represent the number of subsequent processes of the current process.

[0104] The weights of the first process parameter, the second process parameter, the third process parameter, the fourth process parameter and the fifth process parameter decrease in turn.

[0105] Within the room range, assuming that there are n components in total, the sorting sequence L is obtained by arranging in descending order of key(k) (the larger value is arranged first). The sorting operator is used:

[0106] L=sort_desc(key(k j )), j∈{1,2,...,n}

[0107] Wherein, the sequence position index j∈{1,2,...,n} satisfies: the larger the value of key(k j ), the component k j is arranged in the position earlier, the priority is higher, and j is smaller (i.e. the sorting is earlier). The sequence L=(k1, k2,.... kn) satisfies:

[0108] key(k1)≥key(k2)≥...≥key(k n )

[0109] Based on the weighted sum model, the standardized attributes are combined with the weights to obtain the key value key(k):

[0110] key(k) =ω1f1’(k)+ω2f2’(k)+ω3f3’(k)+ω4f4’(k)+ω5f5’(k)

[0111] Wherein, f1’(k) is the value of the first process parameter, f2’(k) is the value of the second process parameter, f3’(k) is the value of the third process parameter, f4’(k) is the value of the fourth process parameter, and f5’(k) is the value of the fifth process parameter; ωi ωi is the weight corresponding to each parameter. The weight ω i satisfies ω1>ω2>ω3>ω4>ω5 to ensure that high-priority attributes (such as whether to touch public space) dominate the comparison. The weight is set in an exponentially decaying form to ensure the priority order in a numerical manner:

[0112] ω i =10 i+a(5-i) , i=1,2,3,4,5

[0113] where a is a non-zero natural number. When a is 2, ω1is 10 9 , ω2is 10 7 , ω3is 10 5 , ω4is 10 3 , and ω5is 10 1 .

[0114] The calculation formula of each process parameter is:

[0115] f i ’(k) =f i (k) / R i , i=1,2,3,4,5

[0116] where R i is the theoretical maximum value or upper bound of parameter i to ensure f i ’(k)∈[0,1]. Optionally, f i ’(k) adopts the rounding standard with a maximum of one decimal place.

[0117] In some embodiments, step S102 includes:

[0118] Step S1021, in the case where the process bounding box occupies the public space, setting the parameter value of the first process parameter to 0.

[0119] Step S1022, in the case where the process bounding box does not occupy the public space, setting the parameter value of the first process parameter to 1.

[0120] The parameter value of the first process parameter is calculated as follows:

[0121]

[0122] If the process bounding box occupies the public space, then ; if the process bounding box does not occupy the public space, then .

[0123] In some embodiments, step S102 further includes:

[0124] Step S1023, if the first process bounding box is completely inside the second process bounding box, it is considered that the first process bounding box and the second process bounding box have a containing relationship.

[0125] Step S1024, for the process bounding boxes having a containing relationship, a space tree is constructed, and according to the depth of the process bounding box in the space tree, the parameter value of the second process parameter is determined.

[0126] The parameter value of the second process parameter is calculated as follows:

[0127] f2(k) =d max -d(k)

[0128] wherein d max is the maximum depth of the space tree, d(k) is the depth of the current process bounding box, the depth of the root node is 0, and the value range is [0, d max ]. The deeper the depth of the process bounding box in the space tree, the later the sorting.

[0129] The third process parameter represents the spatial relationship between the completed component and other component process bounding boxes, that is, the coupling degree sorting (optionally, the coupling degree is represented by the number of collisions) of occupying other component process spaces caused by completing a component, and the higher the coupling degree, the later the process.

[0130] The parameter value of the third process parameter is calculated as follows:

[0131] f3(k) =C max -C(k)

[0132] wherein C max is the maximum number of collisions, and C(k) is the number of collisions caused by the completion of the current component with other process bounding boxes. It should be noted that here, after the completion of the component, the coupling degree (number of collisions) between the directional bounding box (OBB) of the component and other process bounding boxes is analyzed.

[0133] The fourth process parameter represents the number of intersection relationships between process bounding boxes, that is, the coupling degree sorting between process bounding boxes, and the higher the coupling degree, the later the process.

[0134] The parameter value of the fourth process parameter is calculated as follows:

[0135] f4(k) =I max -I(k)

[0136] wherein I max is the maximum number of intersections, and I(k) is the number of intersections between the current process bounding box and other process bounding boxes.

[0137] The fifth process parameter represents the number of subsequent processes corresponding to the process. According to the priority of the subsequent processes, the longer the time, the higher the priority.

[0138] The parameter value of the fifth process parameter is calculated according to the following formula:

[0139] f5(k) = S(k)

[0140] Where S(k) is the number of subsequent processes corresponding to the current process.

[0141] The priority sorting in this embodiment can be modified according to the actual engineering situation. For example, when the common space T, the function related room completes the component installation or other alternative public space appears, the common space SP is determined to be eliminated, triggering the space occupation coupling degree sorting engine to reorder. It should be noted that when the construction space component corresponding to the common space T is completed, the common space T is eliminated, and the space constraint determination of the component k is changed to a non-touching state.

[0142] The BIM components in the space range are calculated according to the quota caliber, the BIM components are calculated according to the quota artificial day consumption, and the "BIM component-WBS-space" is established to calculate the ternary mapping period, and the WBS task in the room bounding box is calculated according to the quota period. Table 6 is a BIM component-WBS-space ternary mapping table according to an embodiment of the present application.

[0143] Table 6

[0144]

[0145] Through the above method, according to the start time of the collection project, considering the flow construction sequence requirements between rooms, the BIM component process priority order of all spaces in the target project is calculated by the space occupation coupling degree sorting engine.

[0146] Continue to refer to Figure 1 After the construction priority is sorted, step S103 is performed.

[0147] Step S103, build a resource total pool and a task set in the construction period, and generate a resource competition model based on the resource total pool, the task set and the construction priority sorting result.

[0148] A total resource pool is established for each period (e.g., a day or a week), and the resources include but are not limited to various types of labor, key tools, equipment, and materials. A resource upper limit is set for each period of the resource pool, for example, the team A has a total of 120 labor days of human resources available for distribution in the day. The components that have been sorted are subjected to resource competition in each period (day / week), and the components with high sorting priority are preferentially allocated resources. If there is a change in the public space (the public space is transformed into an associated construction area, disappears, or is transferred, etc.) in each period, the spatial coupling degree sorting and resource competition are re-performed.

[0149] The resource pool vector R is:

[0150]

[0151] where j is the resource type, J is the set of resource types, k is the time, and r jk is the total upper limit of resource j on the kth day.

[0152] The "WBS-BIM component-space" ternary mapping relationship is extracted, and the task set k is established on the kth day.

[0153]

[0154] u i represents the ith task, and N is the total number of tasks.

[0155] In some embodiments, the total resource pool includes a daily total resource, and the task set includes priority tasks and ordinary tasks; step S103 specifically includes:

[0156] Step S1031, determine the unit time consumption resource of each period of the priority task, and determine the unit time remaining resource according to the unit time consumption resource and the unit time total resource.

[0157] Step S1032, based on the unit time remaining resource and the construction priority sorting result of each ordinary task, a resource competition model is constructed.

[0158] For example, when the unit time is a day, u ij represents the daily resource j demand of task i, and priority is the priority task set in the task set (there are tasks that must be constructed first objectively), and tes is the ordinary task set in the task set

[0159] The resource occupation of the priority task is considered:

[0160] r jk ’ = r jk - upj

[0161] wherein, u pj is the total amount of resources j occupied by daily priority task p, r jk ’ is the total amount of remaining resources j on the kth day.

[0162] In step S104, the construction strategy and the resource allocation strategy corresponding to the construction strategy are obtained according to the resource competition model and the resource condition of the resource total pool.

[0163] According to the construction priority ranking result of the resource competition model, the resources are allocated to the priority task first, and then the remaining resources are allocated to the ordinary task. Specifically, according to the measured engineering quantity in the space range, the standard quota consumption of the process, and the time limit for the project, the spatial constraint upper limit of the resource quantity is considered, and the resource quantity is arranged.

[0164] It should be noted that the resource total pool can be adjusted according to the actual situation, for example, when the resource total pool of a certain resource is not used for many days, the resource total pool is reduced to save cost.

[0165] In actual engineering, the resource pool upper limit can be temporarily increased to consider the rush period. In addition, at the end of each period or when the public space SP is eliminated, the space occupancy coupling degree sorting engine and the construction resource competition model need to be re-executed. Figure 2 is a resource competition model running flowchart according to an embodiment of the present application.

[0166] Through the above steps, according to the process method of the BIM component, a three-dimensional "process bounding box" representing the space required for the construction of each component is automatically generated, not only considering the component itself, but also considering the space required for dynamic construction. Space conflicts and work surface interference that may occur during construction can be discovered and avoided in advance, ensuring the reliability and executability of the progress plan.

[0167] Quantifying the space relationship and process sequence into calculable process parameters, and combining with the weight, realizes the automatic sorting of the construction priority, avoids the deviation and mistake of subjective judgment, and improves the accuracy of decision-making.

[0168] The resource competition model realizes the precise input of resources, avoids the idle and accumulation of resources in the construction site, and solves the problem of low utilization rate of mechanical and electrical engineering resources.

[0169] It should be noted that the steps shown in the above flowchart or the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
