Description

Technical Field

[0001] The present invention relates to the technical field of modular component pre-assembly technology, and in particular to a modular component pre-assembly simulation system and method based on BIM technology. Background Art

[0002] With the continuous advancement of technology, digital technology has been widely used in the field of construction. Among them, digital simulation pre-assembly technology is a technological innovation that has been widely used in large-scale steel structure projects in recent years. Digital simulation pre-assembly technology refers to the simulation of steel structure parts to be assembled through BIM modeling and simulation technology before actual construction, simulating the assembly process of the structure, and predicting and solving problems in the assembly process, such as collision testing, so as to increase construction sales and reduce construction risks.

[0003] However, in the application of pre-assembly systems, there may be situations where modules need to be changed due to practical factors. The existing technology often requires another collision test to be performed for the BIM model update after the change, and the parameter change of one module often causes the parameter change of multiple other modules. The collision test of different modules will be a tedious workload. Therefore, it is worth studying how to effectively analyze and predict the occurrence of collision events based on historical data models when module change events occur to reduce the algorithm complexity and data storage space pressure of layout collision tests. Summary of the invention

[0004] The purpose of the present invention is to provide a modular pre-assembly simulation system and method based on BIM technology to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: a modular pre-assembly simulation method based on BIM technology, the method comprising the following specific steps:

[0006] Step S100: extracting module change events recorded after the pre-assembly of module parts using BIM technology. Module change events refer to events in which the corresponding parameters of module parts are changed after pre-assembly and the BIM model is updated. Each change of a module part is recorded as a module change event. Extract all module change events recorded in the same BIM model, determine the initial changed module parts of each module change event and the corresponding associated module group;

[0007] Step S200: Based on the associated module group, searching for the collision test event after the associated module group is updated in the BIM model in each module change event and recording the collision test parameters; analyzing the parameter change index of each associated module group;

[0008] Step S300: based on the parameter change index of each associated module group, extracting collision test parameters under a number of collision test events corresponding to the same associated module group and the number of modules in the associated module group, and constructing a first change response model of the same type of associated module group;

[0009] Step S400: Based on the first change response model, respond to and judge the change operation after the pre-assembly of the real-time module parts and issue an early warning.

[0010] Avoid algorithm processing pressure and storage space pressure caused by the splicing system when processing multiple change events.

[0011] Further, determining the initial changed module components and the corresponding associated module groups of each module change event includes the following specific processes:

[0012] Initial change module refers to a module in which parameters of the first pre-assembled module or parts contained in the module are changed based on the BIM model in a module change event;

[0013] Obtaining the path planning of the initial change module recorded in the pre-assembly system, extracting the module having a direct connection path with the initial change module from the path planning as the first module and generating a first module set A1, wherein the direct connection path refers to the path formed by adjacent connected module components in the path planning;

[0014] Extract other module components updated based on the BIM model before the next module change event occurs as second module components and generate a second module component set A2;

[0015] The first module component set A1 and the second module component set A2 are combined to form an associated module group corresponding to the initial module component; and the initial changed module component is stored and recorded in the corresponding associated module group.

[0016] The purpose of analyzing the associated module group is to quickly determine other modules that need to change parameters when the module changes based on the BIM model, saving the system space and time for analyzing the parameters of each module, and improving the convenience of model changes and modifications from the perspective of data dependency.

[0017] Furthermore, step S200 includes the following specific steps:

[0018] Step S210: The collision test events include hard collision, soft collision and time collision. The collision test parameters include the collision module object and hard collision parameters of the hard collision, the collision module object and soft collision parameters of the soft collision and the response update time interval T1 of the collision module object recorded in the time collision in the BIM model. The collision module object includes at least two modules, and at least one module is a module in the associated module group.

[0019] Step S220: taking the module marked as the collision module object in the associated module group as an analysis unit, and when other collision module objects in the same collision test event recorded in the analysis unit do not belong to the module in the associated module group, the names of other collision module objects are associated and stored;

[0020] Step S230: Obtain the path length L1 recorded in the path planning corresponding to the initial change module in each analysis unit for the collision module component, where the path length refers to the difference between the pre-assembly sequence number in the path planning where the collision module component is located and the pre-assembly sequence number corresponding to the initial change module; obtain the number of parameter types N1 and the parameter change amount E1 of the parameter values ​​of the collision module component before and after the change in each analysis unit, where E1=e1-e2, where e1 represents the parameter value after the corresponding type parameter is changed, and e2 represents the parameter value before the corresponding type parameter is changed, using the formula:

[0021] D1=c1×(L1 / L0)+c2×(N1 / N0)+c3×[(1 / N1)∑(E1 / e1)];

[0022] Calculate the independent change index D1 of the collision module in each analysis unit, where L0 represents the total path length of the collision module in the path planning corresponding to the initial change module, the total path length refers to the total sequence number recorded after the initial change module pre-joining judgment is realized, N0 represents the total number of parameter types recorded corresponding to the collision module; c1, c2 and c3 represent the corresponding reference coefficients, c1+c2+c3=1, and c1, c2 and c3 are all greater than zero;

[0023] Step S240: extract the independent change index D1 corresponding to all analysis units recorded in the associated module group, and calculate the corresponding parameter change index F in each associated module group, F=(1 / m)∑D1, where m represents the total number of analysis units recorded in the associated module group.

[0024] Furthermore, step S300 includes the following specific steps:

[0025] Step S310: The same type of associated module group means that the modules recorded in the associated module group are the same, and the minimum response update time interval T of the collision module object recorded in the time collision in the collision test parameters of the same type of associated module group in the BIM model is extracted. min , the minimum time interval T of the response update min As the dependent variable parameter of the associated module group under the corresponding collision test event;

[0026] Step S320: Take each parameter change index F recorded in the same type of associated module group as independent variable one, and the actual collision module component ratio R1 recorded in the corresponding module change event as independent variable two, R1=R2 / R0, wherein R2 represents the number of collision module components that are actually hard collisions and soft collisions in the associated module group in the corresponding module change event; R0 represents the number of module components in the associated module group; take independent variable one and independent variable two as input values, and the dependent variable parameters recorded in the corresponding module change event as output values; construct a first change response model t, t=k1×F+k2×R1+ε; substitute several groups of input values ​​and output values ​​recorded in the same type of associated module group, calculate the corresponding correlation coefficients k1, k2 and error term ε, and generate the first change response model corresponding to each type of associated module group.

[0027] Further, step S400 includes the following:

[0028] Step S410: obtaining the real-time initial change module corresponding to the change operation after the pre-assembly of the real-time module is completed, traversing the historical associated module group to determine the real-time associated module group corresponding to the real-time initial change module, extracting the parameter type recorded in each module in the real-time associated module group, matching the collision module object and parameters recorded in the same historical associated module group, and when the same parameter type and the same corresponding collision module object exist in real time, outputting the corresponding module of the real-time associated module group as a suspicious collision module;

[0029] Step S420: Based on the suspected collision module, a warning output of the collision type and the collision module object is performed; and the suspected collision module is substituted as the collision module into the calculation parameter change index F in step S200, and the real-time estimated collision module ratio is obtained, and substituted into the corresponding first change response model to output the minimum value T0 of the estimated response update time interval;

[0030] Step S430: Based on the estimated minimum response update time interval T0, an early warning signal is transmitted to remind the real-time splicing module to update all associated module groups based on the BIM model within the T0 time range after the real-time change of the module.

[0031] Because time collisions may occur if the BIM model fails to update all the modules that need to be changed in a timely manner beyond the T0 time range; this application combines historical data analysis from the perspective of data models to effectively save the collision test calculation time and cost of the overall pre-assembled modules when changing some modules in real time, and can ensure collision assessment warnings after the changes, so that after the changes are confirmed and the BIM model is updated, timely warnings can be effectively made for the collision risks caused by the changed modules, not only from the conventional hard collisions and soft collisions, but also effectively predicting the time collisions caused by the failure to update the BIM model in a timely manner.

[0052] Example: Figure 1As shown, the present invention provides a modular pre-assembly simulation system and method technical solution based on BIM technology, a modular pre-assembly simulation method based on BIM technology, and the method includes the following specific steps:

[0053] Step S100: extracting module change events recorded after the pre-assembly of module parts using BIM technology. Module change events refer to events in which the corresponding parameters of module parts are changed after pre-assembly and the BIM model is updated. Each change of a module part is recorded as a module change event. The parameters include position parameters, model type parameters, etc. Extract all module change events recorded in the same BIM model, determine the initial changed module parts of each module change event and the corresponding associated module group;

[0054] Step S200: Based on the associated module group, searching for the collision test event after the associated module group is updated in the BIM model in each module change event and recording the collision test parameters; analyzing the parameter change index of each associated module group;

[0055] Step S300: based on the parameter change index of each associated module group, extracting collision test parameters under a number of collision test events corresponding to the same associated module group and the number of modules in the associated module group, and constructing a first change response model of the same type of associated module group;

[0056] Step S400: Based on the first change response model, respond to and judge the change operation after the pre-assembly of the real-time module parts and issue an early warning.

[0057] Avoid algorithm processing pressure and storage space pressure caused by the splicing system when processing multiple change events.

[0058] Determine the initial changed module and the corresponding associated module group of each module change event, including the following specific processes:

[0059] Initial change module refers to a module in which parameters of the first pre-assembled module or parts contained in the module are changed based on the BIM model in a module change event;

[0060] Obtaining the path planning of the initial change module recorded in the pre-assembly system, extracting the module having a direct connection path with the initial change module from the path planning as the first module and generating a first module set A1, wherein the direct connection path refers to the path formed by adjacent connected module components in the path planning;

[0061] Extract other module components updated based on the BIM model before the next module change event occurs as second module components and generate a second module component set A2;

[0062] The first module component set A1 and the second module component set A2 are combined to form an associated module group corresponding to the initial module component; and the initial changed module component is stored and recorded in the corresponding associated module group.

[0063] The purpose of analyzing the associated module group is to quickly determine other modules that need to change parameters when the module changes based on the BIM model, saving the system space and time for analyzing the parameters of each module, and improving the convenience of model changes and modifications from the perspective of data dependency.

[0064] Step S200 includes the following specific steps:

[0065] Step S210: The collision test events include hard collision, soft collision and time collision. The collision test parameters include the collision module object and hard collision parameters of the hard collision, the collision module object and soft collision parameters of the soft collision and the response update time interval T1 of the collision module object recorded in the time collision in the BIM model. The collision module object includes at least two modules, and at least one module is a module in the associated module group.

[0066] Step S220: taking the module marked as the collision module object in the associated module group as an analysis unit, and when other collision module objects in the same collision test event recorded in the analysis unit do not belong to the module in the associated module group, the names of other collision module objects are associated and stored; one analysis unit only records one collision module;

[0067] Step S230: Obtain the path length L1 recorded in the path planning corresponding to the initial change module in each analysis unit for the collision module component, where the path length refers to the difference between the pre-assembly sequence number in the path planning where the collision module component is located and the pre-assembly sequence number corresponding to the initial change module; obtain the number of parameter types N1 and the parameter change amount E1 of the parameter values ​​of the collision module component before and after the change in each analysis unit, where E1=e1-e2, where e1 represents the parameter value after the corresponding type parameter is changed, and e2 represents the parameter value before the corresponding type parameter is changed, using the formula:

[0068] D1=c1×(L1 / L0)+c2×(N1 / N0)+c3×[(1 / N1)∑(E1 / e1)];

[0069] Calculate the independent change index D1 of the collision module in each analysis unit, where L0 represents the total path length of the collision module in the path planning corresponding to the initial change module, the total path length refers to the total sequence number recorded after the initial change module pre-joining judgment is realized, N0 represents the total number of parameter types recorded corresponding to the collision module; c1, c2 and c3 represent the corresponding reference coefficients, c1+c2+c3=1, and c1, c2 and c3 are all greater than zero;

[0070] As shown in the embodiment: if the collision module recorded by the analysis unit is a collision module object recorded in time collision, then the corresponding parameter variation e1 is the response update time interval T1 of the corresponding collision module in the BIM model, and e2 is the response splicing time interval of the collision module after the previous module is spliced ​​in the pre-splicing process based on the path planning;

[0071] Step S240: extract the independent change index D1 corresponding to all analysis units recorded in the associated module group, and calculate the corresponding parameter change index F in each associated module group, F=(1 / m)∑D1, where m represents the total number of analysis units recorded in the associated module group.

[0072] Step S300 includes the following specific steps:

[0073] Step S310: The same type of associated module group means that the modules recorded in the associated module group are the same, and the minimum response update time interval T of the collision module object recorded in the time collision in the collision test parameters of the same type of associated module group in the BIM model is extracted. min , the minimum time interval T of the response update min As the dependent variable parameter of the associated module group under the corresponding collision test event; the difference in the parameters recorded in the collision test event is due to the different change requirements of the module parts based on the BIM model; and the collision test event will be recorded after each module change event in the history record;

[0074] Step S320: Take each parameter change index F recorded in the same type of associated module group as independent variable one, and the actual collision module component ratio R1 recorded in the corresponding module change event as independent variable two, R1=R2 / R0, wherein R2 represents the number of collision module components that are actually hard collisions and soft collisions in the associated module group in the corresponding module change event; R0 represents the number of module components in the associated module group; take independent variable one and independent variable two as input values, and the dependent variable parameters recorded in the corresponding module change event as output values; construct a first change response model t, t=k1×F+k2×R1+ε; substitute several groups of input values ​​and output values ​​recorded in the same type of associated module group, calculate the corresponding correlation coefficients k1, k2 and error term ε, and generate the first change response model corresponding to each type of associated module group.

[0075] Step S400 includes the following:

[0076] Step S410: obtaining the real-time initial change module corresponding to the change operation after the pre-assembly of the real-time module is completed, traversing the historical associated module group to determine the real-time associated module group corresponding to the real-time initial change module, extracting the parameter type recorded in each module in the real-time associated module group, matching the collision module object and parameters recorded in the same historical associated module group, and when the same parameter type and the same corresponding collision module object exist in real time, outputting the corresponding module of the real-time associated module group as a suspicious collision module;

[0077] Step S420: Based on the suspected collision module, the warning outputs the collision type and the collision module object; and substitutes the suspected collision module as the collision module into the calculation parameter change index F in step S200, and obtains the real-time estimated collision module ratio, and substitutes it into the corresponding first change response model to output the minimum value of the estimated response update time interval T0; the real-time estimated collision module ratio is based on the ratio of the number of suspected collision modules with collision types of hard collision and soft collision to the total number of all modules in the associated module group;

[0078] Step S430: Based on the estimated minimum response update time interval T0, an early warning signal is transmitted to remind the real-time splicing module to update all associated module groups based on the BIM model within the T0 time range after the real-time change of the module.

[0079] Because time collisions may occur if the BIM model fails to update all the modules that need to be changed in a timely manner beyond the T0 time range; this application combines historical data analysis from the perspective of data models to effectively save the collision test calculation time and cost of the overall pre-assembled modules when changing some modules in real time, and can ensure collision assessment warnings after the changes, so that after the changes are confirmed and the BIM model is updated, timely warnings can be effectively made for the collision risks caused by the changed modules, not only from the conventional hard collisions and soft collisions, but also effectively predicting the time collisions caused by the failure to update the BIM model in a timely manner.
