Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit or scope of the invention, which is therefore not limited to the specific embodiments disclosed below.
The technical problems to be solved by the invention are as follows: aiming at the current assembly type building, the assembly type scheme generating tool which is high in efficiency, strong in reusability and capable of being flexibly adjusted is provided. In order to solve the above-mentioned problems, the inventors have studied the related patent technologies before designing the solution of the present invention, and have found the following.
Chinese patent application No. 202211498194.3 discloses an assembly rate computing platform for an assembled building based on an IFC model, which can perform IFC standardization on non-IFC components, but cannot classify components which are easy to process in batches, and cannot classify similar items, and cannot automatically screen and generate a proper assembly rate design scheme for whether assembly is performed or not.
Chinese patent application No. 201811148798.9 discloses a building outline model generation method, which can identify the outline of a building member, classify the outline, and disassemble the outline according to different building parts, so that the outline model generation method is convenient for prefabricated production of assembly. But cannot automatically generate a construction solution and cannot dynamically adjust an assembly solution.
Chinese patent application No. 202110721034.X discloses a BIM-based assembly rate calculation method, based on a BIM model, the assembly rate of the BIM model can be automatically calculated under the guidance of user instructions, and although user interaction is realized, complicated user selection workload is increased, and an assembly scheme cannot be automatically generated.
Chinese patent application No. 202110711780.0 discloses an assembled building information model design platform, which enables an assembled design to realize the co-design and cooperation of each component, but at the same time, cannot generate an assembly rate and a scheme thereof.
Therefore, none of the above solutions solves the technical problems to be solved by the present invention. The inventors classified the existing problems and continued intensive studies as follows.
(1) Aiming at the problem of assembly rate design efficiency: complicated manual calculation or point selection is used for calculating the assembly rate, the efficiency is low, the limitation of trial and error always exists, the experience of manual selection is also relied on, and the whole assembly scheme is time-consuming to select and has low efficiency.
(2) Problems in terms of implementation feasibility for assembly rate design: the assembly type components used for calculation are manually selected, and the proper assembly rate of 'splicing' is removed, so that the selection is more random, and for the assembly type, the components with strong reusability are the mode with higher assembly efficiency, so that the existing building components are required to be classified and classified according to reusability, and the later assembly is facilitated.
(3) Problems in terms of design flexibility for assembly rate design: in the design, different from other industrial screening problems, the flexible replacement requirement on products is not high, the design problem of the assembly rate is complex, other professional requirements (such as water resistance, fire resistance, beam slab holes and the like) need to be comprehensively considered, and part of components need to be flexibly adjusted in the assembly scheme or not, so that a building or structural designer can conveniently globally adjust the assembly scheme of the whole building.
In combination with the above, the technical problems to be solved by the invention and the realization thinking are further clarified: there is a need for a tool for automatically generating an assembly plan that achieves efficient reuse classification at a early stage of assembly plan generation, and that can be dynamically adjusted and planned at a later stage of assembly plan generation.
In view of the above technical problems, the method for generating the construction horizontal component assembly scheme provided by the invention can classify the construction components according to the condition of multiplexing feasibility, automatically generate the assembly scheme (whether to assemble) under the condition of the assembly rate designated by a user, and dynamically adjust (must assemble or prohibit to assemble) the construction components based on the scheme. Finally, the user-approved assembly rate scheme is obtained after user confirmation.
The method comprises the following steps: the invention achieves the purposes of quickly identifying and reading the user input plane component and quickly generating the assembly scheme according to the input assembly rate by creating the arithmetic unit on the low-code platform. The invention realizes the purpose of flexibly controlling whether building components need to be assembled by designers through the early-stage interactive design; classifying the input building components in the same type, and intensively selecting or discarding the same type of building components to realize the improvement of the component multiplexing rate of the building components with the assembly rate and the enhancement of the implementation operability of the assembly prefabrication production; on the basis of similar multiplexing, a dynamic planning and temperature reduction algorithm taking a preset assembly rate as a final target is designed, and under the condition of ensuring interaction of designers, the assembly scheme of the rest building components is dynamically planned, so that the preset assembly rate target is realized. The method is a prototype algorithm design, and has good cross-platform application potential.

Ra=（Sa1+Sh1_a1）/（（Sa1+Sna1）+（Sh1_a1+Sh1_na1））=（Sa1+Sh1_a1）/（Sh-So）。
while the member Ca1 that must be assembled and the member Cna1 that is prohibited from being assembled are designated by the user through the interaction.
Then, the fitting ratio Ra1 for the free fitting member: ra1 = sh1_a1/Sh1.
Thus, the free-fitting component fitting rate Ra1 can be solved from the ideal horizontal component fitting rate Ra: ra1 = sh1_a1/sh1= ((Sh-So) ×ra-Sa 1)/Sh 1.
Wherein:
lv is the vertical component layer (column and shear wall), cv is the vertical component, sv is the sum of the areas of the column and the shear wall vertical component, sh1_na1 is the area of component Ch1_na1 which is not required to be assembled, sh1_a1 is the area of component Ch1_a1 which is required to be assembled.
Lo is the hole pattern layer, co is the hole, so is the sum of the hole areas.
Lh is the (beam) horizontal member layer, ch is the horizontal member, and Sh is the sum of the areas of the horizontal members.
La is the layer that must be assembled, ca1 is the horizontal member that must be assembled, sa1 is the sum of the areas of the horizontal members that must be assembled.
Lna is the no-fit layer, cna1 is the no-fit horizontal member, and Sna1 is the area summation of the no-fit horizontal member.
Ch1 is a freely assembled horizontal member, and is all horizontal members after the horizontal member Ch removes the necessary assembled horizontal member Ca1 and the prohibited assembled horizontal member Cna 1.
Ra is the ideal target assembly rate of the horizontal component input by a user, ra1 is the assembly rate of the horizontal component which is freely assembled, raz is the assembly rate of the horizontal component of the automatic generation scheme, and Razz is the assembly rate of the horizontal component of the generation scheme after the interactive adjustment of the user.
Since Ra1 is already solved from Ra at this time, whether or not the member is assembled and the number of the assembled member are not clearly defined for the freely assembled horizontal member Ch 1. In order to reduce the production cost of the assembled component, improve the prefabricated template multiplexing rate of the assembled component and facilitate the subsequent calculation of the assembled scheme, the freely assembled horizontal component Ch1 is divided into types according to the graphic characteristics (the prefabricated replicability) and numbered in sequence according to the types, and the similar components are taken as a group of characteristics to consider whether the same components are assembled or not. Ra1 is input S43 with the categorized component sequence Ch1 with the component number for generating an assembly plan.
S43, an assembly scheme generating algorithm.
The assembly type scheme generating algorithm module automatically solves the non-assembly horizontal component scheme under the control of the non-assembly rate 1-Ra1 based on dynamic programming and a temperature reduction algorithm; the ratio of the sum of the areas of the non-assembled horizontal members of the scheme to the total area of all the free-assembled horizontal members Ch1 is defined as the free non-assembly rate; the algorithm target of the free non-assembly rate is closest to but not more than 1-Ra1, the limited non-assembly horizontal component scheme obtained under the control of the algorithm target strips the part of the free assembly component which does not need to be assembled with the component Ch1_na1, and the rest free assembly component is the non-assembly rate horizontal component scheme which needs to be assembled with the component Ch1_a1, so that the free assembly horizontal component Ch1 can be obtained.
The specific algorithm flow is as follows:

Defining a fetching function: a certain component group existing in the container pool is randomly taken out, and the assembly scheme (0 or 1 switch of the non-assembly scheme group) is correspondingly adjusted.
Defining a put function: a certain set of components that does not exist in the container pool is randomly placed and the assembly scheme (0 or 1 switch of the non-assembly scheme set) is adjusted accordingly.
A core iteration function is defined.
Three external transfer parameters are defined: (1) optimal scheme, (2) temperature parameter, (3) balancing times.

If it is in the non-assembled container pool, it is fetched (call fetch function) and other component groups are placed (call put function) in the non-assembled container pool.
But if the component group is not in the non-assembled container pool, then the existing component group already in the non-assembled container pool is placed directly (call put function) or replaced (call fetch or put function).
And calculating the caching result of the current temporary test solution, and calling a statistical function to solve the area of the non-assembled component of the test solution.
If the assembly rate exceeds 1-Ra1, the area of the unassembled component is larger than the capacity of the unassembled container pool, the solution is illegal, and when illegal solution is encountered, the solution is skipped, and the solution does not meet the basic assembly rate Ra1 requirement.
If the value of the temporary solution temp is better than the value of the historical optimal solution, the global optimal solution is updated, and the test solution is stored as an optimal assembly solution (a copy function is called).
If the value of the temporary solution temp is better than the value of the current solution now, the new solution is accepted directly and the test solution is stored as the existing assembly solution (the copy function is called).
Otherwise, it will be considered to accept the solution and define g as the judgment parameter of the natural exponent power, g=1.0 (temp-now)/T.
(g must be less than 0 because the temporary solution temp < the current solution now at this time), T is the temperature parameter passed by the main function to the iterative function, and T is a positive number.
If the random number between one (0, 1) is smaller than the g-th power of the natural constant e, then the inferior solution is accepted and the test solution is stored as an existing non-assembly solution.

User information is input by the user at the time of S2, and meanwhile, the user specifies that the target assembly rate of the case is 0.7 (70.00%), the maximum beam width is 0.3m and the drawing tolerance is 0.005m.
After the building plan is automatically generated by the method of the invention, as shown in fig. 3, the calculation is performed in the figure, and the user is prompted that the actual assembly rate is 0.700472. In fig. 3, the grid-like filling area 100 is a fitting member, and the star-like filling area 200 is a cast-in-place (non-fitting) member.
