Description

Technical Field

[0001] The present application relates to the field of building construction technology, and in particular to a bolt construction control method and system in a building construction scenario. Background Art

[0002] During the construction process, bolts need to be installed to connect and fix the building structure. The traditional bolt installation method is generally determined by manual measurement and layout to determine the installation position and installation method (embedded depth, elevation, exposed length) of the bolts. This operation is easily affected by the construction site environment or human influence, resulting in the actual installation position of the bolt being disconnected from the pre-designed installation drawing position and position deviation, which in turn affects the installation effect. In other words, the traditional manual bolt construction method has the problems of large installation errors and poor installation quality, so it needs to be improved. Summary of the Invention

[0003] In order to reduce bolt installation errors and optimize the bolt installation effect during construction, the present application provides a bolt construction control method and system in a construction scenario.

[0004] In a first aspect, the present application provides a bolt construction control method in a building construction scenario, comprising:

[0005] Receive construction instructions, obtain and analyze the construction scenarios corresponding to the construction instructions, and build the corresponding BIM models;

[0006] Based on the construction scenario, calling a preset decision tree to match a bolt installation plan for the BIM model; wherein the bolt installation plan includes at least bolt attributes and installation parameters;

[0007] The corresponding bolt installation scheme is simulated in the BIM model to generate an installation effect; the installation effect is combined with the bolt installation scheme and then outputted so that construction personnel can know the bolt installation scheme.

[0008] By adopting the above technical solutions, the decision tree rule library replaces manual experience to ensure that the bolt properties are strictly and highly matched with the construction scenario. Simulation and rehearsal operations are used to expose potential conflicts and performance defects in advance. The BIM model integrates the data of the entire design, construction and operation and maintenance cycle to improve the intelligence and high precision of the bolt construction process and optimize the construction and installation quality of the bolts.

[0009] Optionally, the construction scenario corresponds to scenario parameters and installation effect indicators;

[0010] The method further comprises:

[0011] Whenever a bolt installation plan is generated, the correspondence between the bolt installation plan, the construction scenario and the BIM model is stored;

[0012] Regularly perform multi-dimensional effect analysis on the bolt properties in the bolt installation plans stored in the historical period, wherein the multi-dimensional effect analysis includes at least the installation effect analysis of a single bolt and the installation effect analysis of any combination of bolts among the bolts matched by the bolt installation plan;

[0013] According to the results of the multi-dimensional effect analysis, a reusable bolt combination is mined, and the reusable bolt combination includes combination characteristics and installation effect indicators. The preset decision tree is updated using the reusable bolt combination obtained by mining; wherein, the combination characteristics include at least bolt attributes, installation parameters, and scenario parameters.

[0014] By adopting the above technical solution, reusable bolt combinations are extracted from historical data so that they can be migrated to subsequent new scenarios for reuse, thereby reusing their installation effects and giving full play to the synergistic effect of the bolt group. In addition, this application uses intelligent analysis instead of manual experience summary to derive reusable bolt combinations, to ensure that the reusable bolt combinations are supported by data.

[0015] Optionally, the periodic multi-dimensional effect analysis of the bolt properties in the bolt installation schemes stored in the historical period further includes:

[0016] Based on the bolt installation schemes stored in historical periods and their corresponding construction scenarios, virtual bolt addition and deletion adjustment operations are performed in the corresponding construction scenarios. The installation effects after the adjustment operations are simulated and evaluated, and beneficial combinations are discovered as reusable bolt combinations.

[0017] By adopting the above technical solution, considering that the reusable bolt combinations excavated from historical periods are limited and difficult to cover complex new scenarios, this solution further proposes to realize the virtual reconstruction of historical construction scenes from the existing layout through virtual addition and deletion, and simulate the installation effect, so as to actively expand the reusable bolt combinations and improve the combination diversity. The newly expanded samples are used to realize the iterative optimization of the preset decision tree, thereby improving the coverage of the preset decision tree and the matching accuracy of the matched bolts.

[0018] Optionally, the method further includes:

[0019] Whenever a reusable bolt assembly is generated, predicting the overall life of the reusable bolt assembly;

[0020] Based on the reusable bolt combination, the installation effect of the corresponding reusable bolt combination is simulated when each bolt in the reusable bolt combination fails individually; the degree of influence of each bolt in the reusable bolt combination on the installation effect of the reusable bolt combination to which it belongs is determined according to the installation effect obtained by the simulation, and the degree of influence is added to the installation effect of the corresponding reusable bolt combination; the degree of influence at least includes the degree of attenuation of the bolt on the overall life.

[0021] By adopting the above technical solution, the chain reaction effect of the failure of a single bolt in a reusable bolt combination on the overall installation effect is predicted, and the degree of impact is quantified based on the impact. Therefore, when a bolt installation plan containing the reusable bolt combination is output after a subsequent successful match, the construction personnel can know the overall life of the reusable bolt combination and the degree of attenuation of the overall life of each bolt, so that the construction personnel can make targeted preventive response plans in advance.

[0022] Optionally, the method further includes:

[0023] For a target bolt in a reusable bolt assembly whose attenuation degree exceeds a preset threshold, analyzing the failure cause of the target bolt and the corresponding failure scenario, and establishing a conflict relationship between the target bolt and the corresponding failure scenario; wherein, if the conflict relationship is satisfied, the target bolt will fail in the corresponding failure scenario;

[0024] The preset decision tree is updated according to the conflict relationship, so that when the construction scene includes scenario parameters corresponding to the failure scene, the bolts matched by the prediction decision tree do not include the target bolt.

[0025] By adopting the above technical solution, in order to avoid only considering the physical scenario when matching bolts and ignoring functional requirements (such as earthquake resistance and moisture resistance), which in turn leads to the risk of hidden failure and the inability to distinguish whether the failure is caused by installation errors, material mismatch or unmet scenario functions, the failure effect of each bolt and the corresponding failure scenario are analyzed, and the decision tree is reversely optimized based on the conflict relationship. For example, a new failure prediction layer is added to the decision tree, and when the construction scenario includes a failure scenario, the matching of the target bolt is prioritized.

[0026] Optionally, the installation parameters include an installation location;

[0027] The calling of a preset decision tree to match a bolt installation solution for the BIM model further includes:

[0028] According to the installation position of each matched bolt, a tolerance domain is defined for each matched bolt, and the installation effect corresponding to the bolt installation scheme when each matched bolt is at different positions within the corresponding tolerance domain is calculated;

[0029] A mapping relationship between the installation position and the installation effect is generated, and the mapping relationship is added to the corresponding bolt installation solution.

[0030] By adopting the above technical solution, by defining the allowable range of installation positions (tolerance domain) for each bolt, the changing pattern of the installation effect of the bolt at different positions within the tolerance domain is calculated, making it easier for construction personnel on site to know and control the construction accuracy of the bolts.

[0031] Optionally, the method further includes:

[0032] Generating candidate installation sequences for all bolts in the reusable bolt assembly, and simulating the installation process of the reusable bolt assembly in the BIM model according to each candidate installation sequence;

[0033] Calculating a maximum offset error corresponding to each candidate installation sequence based on a tolerance domain of each bolt in the reusable bolt assembly, wherein the maximum offset error refers to an offset relative to the coordinates of a center point of the tolerance domain;

[0034] The candidate installation sequence with the smallest maximum offset error is taken as the optimal installation sequence, and the corresponding relationship between the reusable bolt combination and the optimal installation sequence is stored;

[0035] Whenever a bolt installation plan is generated, and the generated bolt installation plan includes a reusable bolt combination, the corresponding optimal installation sequence is added to the corresponding bolt installation plan.

[0036] By adopting the above technical solution, when actually installing each bolt in the bolt combination, in order to avoid the problem of excessive position offset of the overall bolt combination caused by the superposition of bolt deviations, the present application proposes to use the actual position of the installed bolts as a constraint condition for subsequent bolt positioning in real time during the installation process, so as to reduce the overall position offset of the bolt combination.

[0037] In a second aspect, the present application provides a bolt construction control system in a construction scenario, which adopts the following technical solutions:

[0038] A construction scene model building module is used to receive construction guidance instructions, obtain and analyze the construction scene corresponding to the construction guidance instructions, and build a corresponding BIM model;

[0039] A bolt installation scheme matching module is used to call a preset decision tree based on the construction scenario to match a bolt installation scheme for the BIM model; wherein the bolt installation scheme includes at least bolt attributes and installation parameters;

[0040] The installation effect preview output module is used to simulate the corresponding bolt installation plan in the BIM model to generate an installation effect; the installation effect is combined with the bolt installation plan and then output so that construction personnel can know the bolt installation plan.

[0041] In a third aspect, the present application provides a bolt construction control device in a construction scenario, comprising a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and execute any of the methods described in the first aspect.

[0042] In a fourth aspect, the present application provides a computer-readable storage medium storing a computer program that can be loaded by a processor and execute any of the methods described in the first aspect.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] In this application, a decision tree rule library is used instead of manual experience to ensure that bolt properties are strictly and highly matched with the construction scenario. Simulation and rehearsal operations are used to expose potential conflicts and performance defects in advance. The BIM model integrates data from the entire design, construction, and operation and maintenance cycle to improve the intelligence and high precision of the bolt construction process and optimize the construction and installation quality of the bolts.

[0045] Furthermore, reusable bolt combinations are extracted from historical data so that they can be migrated to subsequent new scenarios for reuse, thereby reusing their installation effects and giving full play to the synergistic effect of the bolt group. In addition, this application uses intelligent analysis instead of manual experience to derive reusable bolt combinations, ensuring that the reusable bolt combinations are supported by data.

[0046] Furthermore, the chain reaction effect of the failure of a single bolt in the reusable bolt combination on the overall installation effect is predicted, and the degree of impact is quantified based on the impact. Therefore, when the bolt installation plan with the reusable bolt combination is output after a subsequent successful matching, the construction personnel can know the overall life of the reusable bolt combination and the degree of attenuation of the overall life of each bolt, so that the construction personnel can make targeted preventive response plans in advance.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0051] The following is combined with Figure 1-2 This application is described in further detail.

[0052] The embodiment of the present application discloses a bolt construction control method in a construction scenario (hereinafter referred to as the construction control method), which aims to analyze the construction scenario and provide construction personnel with a bolt installation plan before they start construction on site for reference. The bolt installation plan includes bolt selection, bolt installation parameters, etc., which replaces manual experience installation, improves the intelligence and high precision of the bolt installation process, and optimizes the construction and installation quality of the bolts. The execution subject of the construction control method is a bolt construction control system in a construction scenario (hereinafter referred to as the construction control system). Figure 1 , specifically explains the execution process of the construction control system for the construction control method.

[0053] S101, receiving construction guidance instructions, obtaining and analyzing the construction scenes corresponding to the construction guidance instructions, and building a corresponding BIM model.

[0054] During implementation, construction workers can access the construction control system via a webpage and enter and trigger construction instructions in a pre-set input box on the construction control system's access interface. For example, if they enter "offshore wind turbine tower foundation," the construction control system extracts keywords from the construction instructions based on a pre-set knowledge graph and AI large model. Based on the keyword library corresponding to each pre-set construction scenario in the knowledge graph, the construction control system ultimately analyzes and determines the construction scenario corresponding to the construction instruction. For example, based on the keywords extracted from the above construction instruction, "wind turbine tower foundation" and "ocean," the construction scenario obtained by matching these keywords can be a wind turbine tower foundation scenario. The corresponding construction scenario specifically includes the physical structure and scenario parameters. The physical structure is "wind turbine tower foundation," and the scenario parameters are "ocean C5 corrosion resistance, 8-degree seismic resistance, and 50 m / s wind load resistance." The construction control system is used to build a tower foundation model (e.g., using Revit) based on the physical structure of the construction scenario. Based on the scenario parameters, it imports the model into ANSYS and adds the corresponding environmental loads.

[0055] S102: Based on the construction scenario, a preset decision tree is called to match a bolt installation plan for the BIM model; wherein the bolt installation plan includes at least bolt properties and installation parameters.

[0056] During implementation, installation parameters include installation location (specifically, the 3D coordinates of the bolts on the BIM model) and embedded depth. The construction control system first uses finite element analysis (FEM) to identify high-stress areas within the BIM model. It then employs the Voronoi algorithm to generate an initial bolt distribution. A gradient descent algorithm is then used to determine the optimal layout, adjusting the layout to meet minimum spacing constraints (according to GB50017). For example, the distance between edge bolts and the concrete edge must be ≥1.5d = 54mm (for M36 bolts) and the center-to-center distance must be ≥3d = 108mm. The system then outputs the total number of bolts obtained from the matching and their 3D coordinates on the BIM model. Concrete parameters are dynamically bounded, and the embedded depth of the bolts is determined through a dual calculation of concrete bond strength and pullout resistance. Furthermore, the installation torque tolerance for bolts in high-stress areas (e.g., ±3%) is stricter than that for bolts in non-high-stress areas (e.g., ±5%).

[0057] Next, based on the preset decision tree, the bolt properties are determined for each of the above-mentioned bolts, combined with the corresponding installation location and the physical structure and scene parameters of the construction scene. Accordingly, the decision tree contains decision nodes for determining the physical structure and scene parameters. The final output bolt properties can include material (such as stainless steel), bolt surface treatment process (such as anti-rust coating), and type (such as hydraulic nut), and finally the matching is completed.

[0058] S103, simulating the corresponding bolt installation plan in the BIM model to generate an installation effect; merging the installation effect with the bolt installation plan and outputting the result so that construction personnel can know the bolt installation plan.

[0059] During implementation, the corresponding positions in the BIM model are marked according to the distribution positions of the bolts obtained through matching, and the bolt properties of the corresponding bolts are added to the marked positions. The installation effect is specifically manifested in the tightening effect of the bolts after installation. Accordingly, the construction control system obtains the stress data of the aforementioned marked BIM model through finite element analysis, and uses Miner's linear cumulative damage theory to calculate the estimated service life. The stress conditions of all positions in the BIM model can be further displayed in the form of a stress cloud map, and the stress magnitude can be described in the form of a color scale. Correspondingly, a life distribution cloud map with a color scale can also be used to visually describe the service life of all positions in the BIM model; thus, the stress data and estimated service life are finally used as installation effect indicators to represent the installation effect. Finally, a bolt installation plan with installation effect is output for construction personnel to use as a reference for bolt installation.

[0060] Optionally, the construction control method further includes the following steps:

[0061] Whenever a bolt installation plan is generated, the correspondence between the bolt installation plan, the construction scenario and the BIM model is stored;

[0062] Regularly perform multi-dimensional effect analysis on the bolt properties in the bolt installation plans stored in the historical period. The multi-dimensional effect analysis includes at least the installation effect analysis of a single bolt and the installation effect analysis of any combination of bolts in the bolt installation plan.

[0063] Based on the results of the multi-dimensional effect analysis, reusable bolt combinations are mined. The reusable bolt combinations include combination features and installation effect indicators. The mined reusable bolt combinations are used to update the preset decision tree. The combination features include at least bolt attributes, installation parameters, and scenario parameters.

[0064] Based on the bolt installation schemes stored in historical periods and their corresponding construction scenarios, virtual bolt addition and deletion adjustments are performed in the corresponding construction scenarios. The installation effects after the adjustments are simulated and evaluated, and beneficial combinations are discovered as reusable bolt combinations.

[0065] During implementation, construction personnel can regularly inspect the usage of bolts after completing the installation, and upload the usage status to the construction control system. Accordingly, the construction control system can regularly conduct multi-dimensional effect analysis on the installed bolts in combination with the corresponding construction scenarios and BIM models. The specific analysis includes the installation effect analysis of a single bolt and the installation effect analysis of the corresponding bolt combination when any number of bolts are combined to form a bolt combination.

[0066] For example, the analysis of the installation effect of a single bolt can be specifically as follows: a wireless force sensor (such as a piezoelectric film) is used to measure the preload force of a single bolt, and the preload force attenuation rate is calculated. The construction control system is used to identify the loosening characteristic frequency (such as a sudden increase in energy in the 5-15Hz frequency band) through vibration spectrum analysis.

[0067] The installation effect analysis of the bolt assembly can be as follows: the stress transfer path between the bolts in the bolt assembly is monitored by a strain gauge array (for example, the edge bolt bears 60% of the load), and the vibration synchronization of all bolts in the bolt assembly is detected by a phase analyzer (for example, the ideal phase difference is set to ≤10°).

[0068] Based on the above analysis results, bolt combinations whose installation effects meet preset conditions (preset conditions can be predefined manually) are discovered as reusable bolt combinations. For example, the DBSCAN algorithm is used to cluster high-performance combinations (for example, "stainless steel M20 + carbon steel M16, with a spacing of 200mm" has a 40% increase in service life in corrosion scenarios). The Apriori algorithm is used to discover frequent combination rules (for example, "shear bolts + seismic washers" have an 85% probability of appearing in beams). The bolt properties, installation parameters, and corresponding installation effects of each bolt in the reusable bolt combination are associated with each other.

[0069] The construction control system also loads historical BIM models and imports corresponding data such as bolt distribution and bolt properties. Finite element simulation identifies high-stress areas (e.g., stress ≥ 80% of yield strength) and low-efficiency areas (e.g., stress ≤ 20% of yield strength). It then implements a virtual addition and deletion strategy, which includes adding bolts with different properties in high-stress areas (e.g., replacing M16 with M20 or adding diagonal reinforcement bolts) and removing redundant bolts in low-efficiency areas (e.g., increasing spacing from 150mm to 200mm). After executing this virtual addition and deletion strategy, the construction control system calculates the adjusted installation performance indicators and selects bolt combinations whose installation performance indicators meet preset conditions (i.e., beneficial combinations) as reusable bolt combinations. Finally, these new reusable bolt combinations are injected into the decision tree rule library to optimize the decision tree.

[0070] Optionally, the construction control method further includes the following steps:

[0071] Whenever a reusable bolt combination is generated, the overall life of the reusable bolt combination is predicted;

[0072] Based on the reusable bolt combination, the installation effect of the corresponding reusable bolt combination is simulated when each bolt in the reusable bolt combination fails individually. The influence of each bolt in the reusable bolt combination on the installation effect of the corresponding reusable bolt combination is determined based on the simulated installation effect, and the influence degree is added to the installation effect of the corresponding reusable bolt combination. The influence degree at least includes the degree of attenuation of the bolt's overall life.

[0073] For target bolts in a reusable bolt assembly whose attenuation degree exceeds a preset threshold, the failure cause of the target bolt and the corresponding failure scenario are analyzed, and a conflict relationship between the target bolt and the corresponding failure scenario is established; if the conflict is satisfied, the target bolt will fail in the corresponding failure scenario.

[0074] The preset decision tree is updated according to the conflict relationship so that when the construction scenario contains scenario parameters corresponding to the failure scenario, the bolts matched by the prediction decision tree do not contain the target bolt.

[0075] In practice, combined with the above technical content, it can be seen that when analyzing the installation effect, an installation effect index of the estimated service life will be obtained, and the overall life here can be considered as the estimated service life obtained above.

[0076] Bolt failure refers to bolt breakage, loosening, or corrosion. Accordingly, the construction control system is used to simulate bolt breakage by removing bolts from the BIM model, and then analyze the stress redistribution of the remaining bolts in the reusable bolt assembly. The construction control system is also used to simulate bolt loosening by reducing bolt stiffness (e.g., returning the preload to zero), and then calculate the vibration transmission change for all bolts in the reusable bolt assembly. The construction control system is also used to gradually reduce the cross-sectional area of ​​the bolts to simulate failure phenomena such as load-bearing capacity degradation and bolt corrosion.

[0077] The construction control system uses the difference in installation performance before and after the simulation as a specific representation of the attenuation level. Bolts with attenuation levels above a preset threshold are then selected as target bolts. Based on the correspondence between bolt types, failure causes, and scenarios resulting from these failure causes (hereinafter referred to as failure scenarios) stored in a preset bolt failure mode library, the system analyzes the failure causes and corresponding failure scenarios for the target bolts. For example, the failure of ordinary carbon steel M16 is caused by salt spray corrosion (0.2mm annual corrosion), and the corresponding failure scenario is a marine environment. In other words, in this failure scenario, ordinary carbon steel M16 will fail due to salt spray corrosion. Another example is that 8.8-grade large hexagonal head bolts are prone to loosening (i.e., the failure cause) due to high-frequency vibration in seismic scenarios (i.e., failure scenarios).

[0078] The construction control system is used to establish a conflict relationship between the target bolt and the failure scenario, and inject the conflict relationship as a negative rule into the preset decision tree rule library, that is, a new failure prediction layer is added to the preset decision tree, so that when traversing the preset decision tree according to the construction scenario to match the bolts, the bolt properties that have a conflict relationship with the scenario parameters of the construction scenario are preferentially excluded; accordingly, when a target bolt with an attenuation degree higher than a preset degree threshold appears in the reusable bolt combination, the scenario parameters of the reusable bolt combination are adaptively adjusted to delete the scenario parameters of the failure scenario that has a conflict relationship with the target bolt from the scenario parameters. This operation is to adjust the applicable scenario of the reusable bolt combination, indicating that the reusable bolt combination is not applicable to the failure scenario.

[0079] Optionally, after "calling a preset decision tree to match a bolt installation plan for the BIM model" in S102, the following steps are further included:

[0080] According to the installation position of each matched bolt, a tolerance domain is defined for each matched bolt, and the installation effect corresponding to the bolt installation scheme when each matched bolt is at different positions within the corresponding tolerance domain is calculated;

[0081] Generate a mapping relationship between the installation position and the installation effect, and add the mapping relationship to the corresponding bolt installation plan.

[0082] Construction control methods also include:

[0083] Generate candidate installation sequences for all bolts in the reusable bolt assembly, and simulate the installation process of the reusable bolt assembly in the BIM model according to each candidate installation sequence;

[0084] Based on the tolerance domain of each bolt in the reusable bolt combination, the maximum offset error corresponding to each candidate installation sequence is calculated. The maximum offset error refers to the offset relative to the coordinates of the center point of the tolerance domain.

[0085] The candidate installation sequence with the smallest maximum offset error is taken as the optimal installation sequence, and the corresponding relationship between the reusable bolt combination and the optimal installation sequence is stored;

[0086] Whenever a bolt installation plan is generated and the generated bolt installation plan contains a reusable bolt combination, the corresponding optimal installation sequence is added to the corresponding bolt installation plan. Whenever the generated bolt installation plan contains a reusable bolt combination, the corresponding optimal installation sequence is added to the corresponding bolt installation plan.

[0087] During implementation, the construction control system will determine a three-dimensional spatial domain (i.e., tolerance domain) in the form of an interval for each bolt based on the three-dimensional coordinates of the installation position of each bolt (hereinafter referred to as the initial coordinate point) and the preset tolerance value, and the tolerance domain includes the initial coordinate point.

[0088] Then, the construction control system discretely samples within the tolerance domain of each bolt to form a coordinate set consisting of actual installation coordinate points. For example, if the actual coordinate point is x, x ∈ [x_min, x_max], [x_min, x_max] is the corresponding coordinate set.

[0089] Then, each actual installation coordinate point is used as the bolt installation position, and the installation effect is analyzed using the previous analysis scheme, so as to finally obtain the installation effect of the bolt at different positions within the tolerance domain (that is, at different actual installation coordinate point values). That is, when the installation position of the bolt obtained by matching is expressed in the form of an interval, all possible installation effects are adaptively output; a mapping relationship between the installation effect and the actual installation coordinate point is established, and the mapping relationship is added to the bolt installation plan and output together with the bolt installation plan for construction personnel to know.

[0090] In addition, the construction control system is also used to generate all possible installation sequences of all bolts in the reusable bolt combination based on the number of bolts contained in the reusable bolt combination (i.e., candidate installation sequences, which are used to describe the installation sequence of the bolts during actual installation). For example, if the reusable bolt combination includes A, B, and C, the corresponding candidate installation sequences include: A, B, C; A, C, B; B, A, C; B, C, A; C, A, B; C, B, A.

[0091] Then, for each candidate installation order, proceed as follows:

[0092] Traverse each bolt in the candidate installation sequence. If it is the first bolt, determine the actual installation coordinate point of the first bolt as the edge coordinate of its coordinate set (such as the maximum coordinate point or the minimum coordinate point).

[0093] Next, for all bolts except the first one, find a location within its tolerance range that meets the following conditions as the actual installation coordinate point:

[0094] For the i-th bolt, select the actual installation coordinate point i from its corresponding tolerance domain so that the distance between the actual installation coordinate point i and each of the previous i-1 bolts is greater than the preset distance value u, and the coordinate point closest to the edge coordinate of the corresponding tolerance domain is selected when the above conditions are met.

[0095] After determining the actual coordinate points of all bolts in the reusable bolt combination, the distance values ​​of the actual coordinate points of each bolt from the center of the corresponding tolerance domain are superimposed and used as the maximum offset error of the corresponding candidate installation sequence.

[0096] In the above manner, the maximum offset error corresponding to all candidate installation sequences of the same reusable bolt combination is obtained, and the candidate installation sequence corresponding to the minimum value of all maximum offset errors is selected as the optimal installation sequence of the corresponding reusable bolt combination. The correspondence between the reusable bolt combination and the corresponding optimal installation sequence is stored so that when the reusable bolt combination is subsequently called to generate a bolt installation plan, the optimal installation sequence can be output accordingly.
